Technical Field

The invention relates to a high polymer molding processing technology, in particular to a mold exchange mechanism of a linear multi-mold station molding processing machine.

Background

In a conventional polymer molding process technology using linear multi-mold stations, a raw material supply unit such as an injection unit or an extrusion unit is moved along a linear rail between a plurality of linearly arranged mold stations, and a polymer raw material is supplied to molds located in the mold stations, thereby performing a polymer molding operation.

The material supply unit, which is traditionally located in a mobile position, is fixed at a fixed material injection mold station in the new chinese patent No. M542562, and then a carrying unit moves a mold, which is located in the material injection mold station and receives the material, to other molding mold stations for molding, and the technology disclosed in the prior art of the new patent can fix the material supply unit, change the carrying unit to carry the mold, and move the mold with a smaller energy demand, thereby achieving the effect of saving resources.

The deficiency of the technology disclosed in the new patent makes it still not ideal in terms of efficiency and resource utilization, in the new patent, the position of the injection molding station to which the raw material supply unit is fixed is located at the end of the straight line, and the conveying unit can only perform one mold movement in one conveying stroke, for example, when the conveying unit takes out one mold from the injection molding station for conveying, the molding station of the first object is required to be empty and to receive the mold to be conveyed, and then another mold is conveyed from the molding station of the second object to the injection molding station to receive the material, so that, while the conveying unit conveys the mold, the injection molding station is in an empty state, and the supply process of the raw material can be performed again after the carrying unit carries another mold back, so that the novel patent is difficult to have higher efficiency or better resource utilization.

Disclosure of Invention

It is therefore a primary object of the present invention to provide a die exchange mechanism for a linear multi-die station molding machine that allows die change for a single die station in a single cycle of travel.

The mold exchanging mechanism of the linear multi-mold station molding machine according to the present invention is to exchange molds in a mold station by a mold exchanging unit, and the mold exchanging unit is capable of simultaneously carrying two molds and moving the two molds carried thereby, so that the molds in a single mold station can be moved out first, and then the molds carried in advance can be moved in, thereby exchanging the molds in the single mold station.

More specifically, the mold exchanging mechanism of the linear multi-mold station molding machine includes a plurality of mold stations arranged in sequence at equal intervals along a virtual reference line; a raw material supply unit fixed on a fixed address; a guide unit which is positioned at one side of the plurality of mould stations which are arranged in a straight line, extends a preset length in parallel with the reference straight line and is adjacent to the plurality of mould stations; a plurality of dies movably located in the plurality of die stations, respectively; the mould exchanging unit is movably arranged on the guiding unit and is guided by the guiding unit to perform reciprocating displacement along the reference straight line.

The mold exchanging unit has one base for holding at least two molds, one first moving part set on the base and capable of making the first combining end capable of combining with and separating from the molds in the extending position near the mold stations and the retracting position far from the mold stations to reciprocate linearly for moving the molds, and one second moving part set on the base and separated from the first moving part to make the second combining end capable of combining with and separating from the molds in the extending position near the mold stations and the retracting position far from the mold stations to reciprocate linearly for moving the molds.

The two molds carried by the base part by the mold exchange unit can be horizontally juxtaposed or vertically layered, and the first moving part and the second moving part are horizontally juxtaposed or vertically layered according to different mold carrying manners, for example, when the two molds are horizontally juxtaposed, even if the first moving part and the second moving part are horizontally juxtaposed, they are also horizontally juxtaposed on the base part.

Furthermore, in order to reduce the moving distance of the single moving cycle of the die exchange unit, the raw material supply unit is addressed to the middle section of the reference straight line, so that the die exchange unit takes the position of the raw material supply unit as the center, and the distance between the raw material supply unit and the two ends of the reference straight line is shortened, so that the moving time and the moving distance of the single moving cycle after the raw material supply unit goes one time are shortened.

The invention has the beneficial effects that: the mold exchanging mechanism of the linear multi-mold station molding processing machine can replace a mold for a single mold station in a single moving period, so as to overcome the defect of poor efficiency and resource utilization caused by taking out the mold or putting in the mold for the single mold station in the single moving period in the prior art.

Detailed Description

Referring to fig. 1 to 5, a mold exchanging mechanism 10 of a linear multi-mold station molding machine according to a preferred embodiment of the present invention mainly includes a plurality of mold stations 20, a plurality of molds 30, a material supplying unit 40, a guiding unit 50, and a mold exchanging unit 60.

The plurality of mold stations 20 are arranged in a linear shape at equal intervals along a virtual reference straight line a, and the specific number thereof is thirteen in this embodiment, and the mold station located at the center of the reference straight line a is used as a material injection mold station for performing a polymer material supply process, and the other twelve mold stations are used as molding mold stations for performing a polymer molding process.

The plurality of molds 30 are multi-piece molds formed by stacking a plurality of mold plates one on top of the other, and form a mold chamber space for receiving the polymer raw material between the stacked mold plates, so as to receive the polymer raw material supplied from the raw material supply unit 40 and mold the raw material in the mold chamber space.

The raw material supply unit 40 is a conventional injection molding apparatus, and is located at one side of a line where a plurality of molding stations 20 are arranged, and is fixedly positioned beside the injection molding station, so that a polymer raw material is supplied to a corresponding mold located in the injection molding station at the fixedly positioned address position.

The guiding unit 50 is a conventional linear guiding technology, and is located at a side of the plurality of mold stations 20 different from the raw material supplying unit 40, and has a base 51 in structure, a pair of parallel linear guiding members 52 are fixed on the base 51, extend along the reference line a, and are close to the positions of the plurality of mold stations 20 for providing a linear guiding direction parallel to the reference line a, a plurality of sliding members 53 are respectively slidably disposed on the guiding members 52, and can be reciprocally linearly displaced along the guiding direction of the plurality of guiding members 52, a rack 54 is fixed on the base 51, and a power member 55 is engaged with the rack 53 by a gear.

The mold exchanging unit 60 has a plate-shaped base 61 fixed to the sliding members 53 and the power member 55 at the bottom side, a first moving portion 62 and a second moving portion 63 are arranged in parallel and spaced apart from each other on the top side of the base 61, and the spacing distance between the first moving portion 62 and the second moving portion 63 is equivalent to the spacing distance between the molds in two adjacent mold stations 20, accordingly, the mold exchanging unit 60 is guided by the guide 52 using the power member 55 as the power source through the engagement between the gear of the power member 55 and the rack 54, moves between the mold stations 20 along the reference line a, and can move different molds by the first moving portion 62 and the second moving portion 63 in a single movement cycle of one round to achieve the mold exchanging effect;

more specifically, the first moving portion 62 has a pair of first guide bars 621 in the form of a long straight bar, which are parallel to each other and are fixed on the upper side of the base portion 61 in a spaced manner, a long axis of the first slider 622 is perpendicular to the reference straight line a, a pair of first guide bars 621 are slidably disposed on the first slider 622, and linearly and reciprocally movable along the major axis of the first guide bars 621, a first driving member 623 constituted by a fluid pressure cylinder member is fixedly provided on the base 61, the output shaft extends above the base 61, a first coupling end 624 is disposed at the shaft end of the output shaft of the first driving member 623 and is fixedly connected to the pair of first sliding blocks 622, the first coupling end 624 is capable of performing a reciprocating displacement perpendicular to the direction of the reference line a under the power action of the first driving element 623 and the guidance provided by the pair of first sliders 622 and the pair of first guide bars 621;

the second moving portion 63 has the same structure as the first moving portion 62, i.e. it has a pair of second guide bars 631 identical to the first guide bars 621, a pair of second sliders 632 identical to the first sliders 622, a second driving member 633 identical to the first driving member 623, and a second coupling end 634 identical to the first coupling end 624.

Accordingly, the first moving portion 62 and the second moving portion 63 respectively drive the first coupling end 624 and the second coupling end 634 to move linearly and reciprocally between an extended position and a retracted position by the power provided by the first driving element 623 and the second driving element 633, so as to move the mold within a respective mold changing stroke of reciprocal movement.

Furthermore, in order to facilitate the combination and separation between the mold exchanging unit 60 and the molds 30, the molds 30 each have a plate-shaped mold seat 31 for the respective mold plates to be overlapped thereon, and a pair of clamping holes 32 are respectively formed on the mold seats 31, and at least an opening is formed on the bottom plate surface of the mold seat 31.

The first combining end 624 has a plate-shaped first sliding seat 6241, which is fixed to the pair of first sliding blocks 622 by the bottom plate surface, and a pair of first locking posts 6242 for locking with the locking holes 32 are protruded on the first sliding seat 6241.

The second coupling end 634 is identical in structure to the first coupling end, and has a second slide 6341 identical to the first slide and a pair of second posts 6342 identical to the first posts.

When the mold is located in the corresponding mold station, the mold clamping or mold releasing procedure is performed by the existing mold clamping mechanism in the mold station, so that the height of the mold is changed, specifically, as shown in fig. 6, when the mold 30 is locked in the mold station 20, it is pushed up and clamped between the upper and lower mold clamping bases, and conversely, when the mold 30 is released in the mold station, the mold 30 is lowered to a position lower than that of fig. 6, as shown in fig. 7;

when the mold 30 moves up and down as shown in fig. 6 and 7, only the first combining end 624 or the second combining end 634 needs to be located at the protruding position, the first locking post 6242 or the second locking post 6342 thereof is located on the shaft of the locking hole 32 corresponding to the mold 30, so that when the mold 30 descends as shown in fig. 7, the mold seat 31 can be locked with the first combining end 624 or the second combining end 634, and conversely, when the mold 30 ascends as shown in fig. 6, the mold 30 can be separated from the first combining end 624 or the second combining end 634.

When the mold exchanging mechanism 10 of the linear multi-mold station molding machine is used, the first moving part 62 and the second moving part 63 move different molds, so that the mold exchanging unit 60 can simultaneously move two molds between two adjacent mold stations and the base part in one moving period, and can also move two molds in different mold stations or the same mold station at different times.

When the mold exchanging mechanism 10 of the linear multi-mold station molding machine is used to exchange molds for different mold stations, not only the mold 30 removal or mold 30 insertion operation can be performed for two adjacent mold stations 20 as shown in fig. 8, but also the mold 30 'removal or mold 30 ″ insertion operation can be performed for the same mold station 20' as shown in fig. 11 and 12 depending on the actual application requirement, as well as the mold exchanging mechanism 10 of the linear multi-mold station molding machine can be used to perform the mold 30 'removal and mold 30 ″ insertion operation for the same mold station 20' as shown in fig. 9 and 10.
