Technical Field

The invention relates to the technical field of injection molding machines, in particular to a mold locking device and a large-scale injection molding machine device.

Background

In the existing injection molding machine standard, the size of the mold clamping force is in a direct proportion relation with the size of the template, namely the larger the mold clamping force is, the larger the positive body of the template is. In the production of the ribbon, the ribbon is narrow and long, so the requirement on the longitudinal height of a machine is only required, and the requirement on the transverse width is not high. If these long bands are to be produced using only conventional standard injection moulding machines, larger machines are used in order to achieve the clamping force and longitudinal height requirements. Firstly, this causes waste of the machine and also increases the cost for the customer; in addition, since the larger the machine, the longer the production cycle for the sake of smoothness, which is equivalent to reducing the capacity of the customer. Secondly, because the whole machine is enlarged by the template, when some narrow and long molds are used for production, the template is stressed unevenly and generates larger deformation, thereby influencing the qualification rate of products.

Preferably, a stress recess 31 formed concavely is provided at any position on the guide post 3.

The clamping force of the machine reaches more than 1000 tons, and the guide pillar 3 is also forced to bear larger stress. The diameter of the primary stress groove may preferably be about 85.5% of the diameter of the non-stressed groove section in the guide pillar 3. The stress relief groove can increase the toughness of the guide post 3, can offset the deformation generated by the stress of the template, and can improve the capability of the guide post to deform after being stretched.

Preferably, the method further comprises the following steps: a hood 9;

the hood 9 at least surrounds the machine hinge mechanism 1 and the die sleeve 2;

the hood 9 includes: side plates 91 and a top cover plate 92;

the top cover plate 92 is installed above the side plate 91 in a reversible manner; the top cover plate 92 is positioned above the machine hinge mechanism 1 and/or the die case 2.

When the formed workpiece is demoulded, if a mechanical arm is not used for pulling out the product, the product is ejected by the ejector pin structure 6, and the formed workpiece is easily thrown to the machine hinge mechanism 1 while being ejected out of the mould. A formed workpiece is easily clamped on the machine hinge mechanism 1, so that the normal die opening and closing action of the die pushing driving component 4 is influenced; and the clamped formed workpiece can be stuck with lubricating oil of the mechanical hinge mechanism 1 to pollute the surrounding working environment. To avoid this, the present solution arranges the top cover plate 92 above the side plate 91; the side plate 91 is used for preventing an internal workpiece from flying out from the inside and preventing an external object from entering the mold locking device 01; the top cover plate 92 has a flip function and can be flipped 180 degrees backward. During normal work, the top cover plate 92 completely covers the die sleeve 2, the injection molding movable die 5 and the upper part of the machine hinge mechanism 1, a molded workpiece is ejected out and then only falls on the top cover plate 92, the molded workpiece cannot fall in the machine hinge mechanism 1 to influence the work of the machine, and the molded workpiece is easy to clean. When maintenance is required, the front half of the top cover plate 92 can be turned over without affecting maintenance work.

A large scale injection molding machine apparatus comprising: the injection molding machine comprises a mold locking device 01, an injection molding movable mold 5, an injection molding fixed mold 8 and an injection molding machine main body 02;

the mold locking device 01 is the mold locking device 01 of any of the above embodiments; the injection movable die 5 is arranged on the die sleeve 2; the injection fixed die 8 is arranged on the guide pillar 3; the output end of the injection molding machine main body 02 acts on the injection molding fixed die 8 and is used for outputting plastics to the injection molding fixed die 8.

The injection molding machine main body 02 is replaced by a known injection molding machine, and a heating ring of a glue injection mechanism 021 in the injection molding machine main body 02 works to preheat a glue melting cylinder; meanwhile, the injection mechanism moves forwards through the injection moving oil cylinder, so that the injection nozzle props against the injection molding fixed die 8. When the glue melting cylinder reaches the preset temperature, the hydraulic pump drives the hydraulic motor to rotate the glue melting screw in the injection molding machine main body 02 and start glue melting. At this time, the mold locking device 01 simultaneously performs mold closing operation on the injection movable mold 5 and the injection fixed mold 8 through the mold pushing driving assembly 4. During melting, the melting screw rod moves back under the thrust of the molten plastic while rotating. When the melting glue screw rod retreats to the pre-molding position, the melting glue in the melting glue cylinder is indicated to reach the glue amount required by the product. At this time, the injection of the glue can be started, that is, the glue melting screw rod is pushed forward through the glue injection oil cylinder, and the molten plastic is injected into the mold through the injection nozzle. After the mold cavity is filled with the molten plastic, the glue injection mechanism maintains the pressure, so that the molten plastic in the mold cavity cannot flow backwards, and the mold is cooled simultaneously. After the molten plastic in the mold cavity is cooled and solidified, the mold pushing driving assembly 4 performs mold opening operation to separate the injection molding movable mold 5 from the injection molding fixed mold 8, and simultaneously, the output end of the ejector pin structure 6 extends out to push out the plastic product left on the injection molding movable mold 5. This completes one injection molding cycle, followed by the next cycle beginning with the same steps.

The injection movable mold 5 and the injection fixed mold 8 are preferably long and narrow molds.

Preferably, the method further comprises the following steps: an injection molding machine base 03; the injection molding machine base 03 is sequentially provided with a first-stage step 031 and a second-stage step 032 from bottom to top;

the machine hinge mechanism 1 and the die sleeve 2 are movably arranged on the first-stage step 031; the injection fixed mold 8 is mounted on the first-stage step 031; the injection molding machine main body 02 is installed at the second step 032.

In this scheme, with die sleeve 2, the movable mould 5 of moulding plastics and mould plastics cover half 8 and set up in one-level step 031, injection molding machine main part 02 sets up in second grade step 032, and die sleeve 2, the movable mould 5 of moulding plastics and the 8 relative positions of the cover half of moulding plastics are less than injection molding machine main part 02 promptly, have reduced the whole height of machine, have reduced the focus of machine, have improved the machine at the die sinking, the stationarity of mode locking motion in-process reduces the vibrations of machine in the motion.
