Technical Field

The invention relates to a foaming mold, in particular to a foaming mold structure.

Background

At present, a foaming mold can be divided into a hard foaming type and a soft foaming type according to the material of a foaming product, the two types of molds need a specific cavity to complete the molding operation of the product, the mold molding needs the characteristic of quenching and sudden heating, so the requirement on the material of the mold cavity is high, the aviation-grade aluminum material is generally adopted for processing, the quenching and sudden heating performance of the aluminum material is good, and the manufacturing of the cavity of a foaming part can be well met.

The wearing and tearing of die cavity die joint can be produced to the foaming part mould of aluminium system in life cycle, the die joint can lead to the fact inhomogeneous clearance when the upper and lower mould closes the mould, and the raw and other materials of foaming part are liquid, it is better at aluminium system mould heat shaping in-process mobility, raw and other materials can spill over through the clearance of upper and lower die cavity die joint wearing and tearing, it has a large amount of deckle edges to cause the product, cause the product qualification rate to reduce, and the workman gets rid of deckle edge's process more loaded down with trivial details, need carry out aluminum product welding process to the die joint of mould die cavity during the maintenance, then reuse digit control machine tool to process, the maintenance duration is.

Disclosure of Invention

In view of the above drawbacks, the present invention provides a foaming mold structure to solve the above technical problems.

The purpose of the invention is realized by the following technical scheme:

the utility model provides a foaming mold structure, including last mould and with go up mould complex lower mould, the lower mould is equipped with the die cavity that is used for the product shaping, it is equipped with the mould die joint to go up the mould lower surface, the lower mould upper surface is equipped with the lower mould die joint, the lower mould die joint with the inclined plane of die cavity junction for having the direction function, the inclined plane is by the periphery to the center from high to low slope, and this kind of structure setting is favorable to liquid foaming part raw and other materials in aluminium system mould thermoforming in-process, is difficult to spill over through the clearance of upper and lower die cavity die joint, and liquid foaming part raw and other materials have the trend of flow direction die cavity, and not excessive, just so causes the product to have a large.

Furthermore, the inclined angle of the inclined surface relative to the horizontal plane is 15-30 degrees, the angle is proper, if the angle is too large, the die closing difficulty of the upper die and the lower die is increased, a gap is easy to exist, and the manufacturing difficulty is increased; if the angle is too small, the liquid flow is not facilitated.

Further, the lower die parting plane comprises a high side lower die horizontal plane and a low side lower die horizontal plane, and the inclined planes comprise a high side lower die inclined plane and a low side lower die inclined plane; the height of the inclined surface of the high-side lower die is lower than the horizontal plane of the high-side lower die; the height of the low-side lower die inclined plane is lower than the horizontal plane of the low-side lower die; first arc-shaped connecting surfaces are arranged between the inclined surface of the high-side lower die and the horizontal surface of the high-side lower die and between the inclined surface of the low-side lower die and the horizontal surface of the low-side lower die.

Furthermore, a first arc transition section is arranged between the upper part of the first arc connecting surface and the horizontal plane of the high-side lower die or the horizontal plane of the low-side lower die, and a second arc transition section is arranged between the lower part of the first arc connecting surface and the inclined plane of the high-side lower die or the inclined plane of the low-side lower die.

Further, the bottom slope of die cavity sets up, the lateral wall vertical setting of die cavity, the inclined plane with the contained angle between the lateral wall of die cavity is the obtuse angle.

Furthermore, the upper die parting surface comprises a high-side upper die horizontal surface, a low-side upper die horizontal surface and a middle bump inclined surface, second arc-shaped connecting surfaces are arranged between the high-side upper die horizontal surface and the bump inclined surface, two ends of the bump inclined surface are respectively provided with an inclined angle matched with the inclined surfaces, when the upper die and the lower die are closed, the bump inclined surface covers the upper part of the die cavity, and two ends of the bump inclined surface are contacted with the inclined surfaces.

Further, a third arc-shaped transition section is arranged between the horizontal plane of the upper die on the high side and the horizontal plane of the upper die on the low side and the second arc-shaped connecting surface.

Further, the horizontal plane of the high-side upper die is matched with the horizontal plane of the high-side lower die; the low side upper die level is matched with the low side lower die level; when the upper die and the lower die are assembled, gaps exist between the horizontal plane of the upper die on the high side and the horizontal plane of the lower die on the high side, between the horizontal plane of the upper die on the low side and the horizontal plane of the lower die, and between the first arc-shaped connecting surface and the second arc-shaped connecting surface, so that the quenching and quenching processes are facilitated.

Further, the foaming mold structure is made of aluminum material.

The parting surface of the foaming mould structure is an inclined surface with a guiding function, the inclined surface inclines from the periphery to the center from high to low, the structural arrangement is favorable for the liquid foaming part raw material to have the tendency of flowing to a mould cavity and not easily overflow through a gap in the heating and forming process of the aluminum mould, so that the product is easily subjected to a large amount of burrs, and the specific advantages are as follows:

(1) the inclined surface has a certain guiding function, so that the liquid raw material does not overflow, and burrs are avoided;

(2) the auxiliary use equipment of the die is reduced, the precision influence of errors on the die is reduced, the repeated errors of the parting line of the upper die and the lower die are improved, and the qualification rate of the die for producing products is improved;

(3) go up mould die joint and lower mould die joint and all set up arcwall face and a plurality of arc changeover portion, make the mould die closing process more flexible from top to bottom, effectively improve mould life, and easy maintenance.
