Abstract

A die assembly structure comprises an upper die and a lower die, wherein the upper die comprises an upper cover board and an upper cover containing an inner kernel, the lower die comprises a lower cover and a lower cover board, a forming cavity containing soles is formed between the lower cover and the inner kernel, cooling conduits are opened in the upper die and the lower die, and the cooling conduits are communicated with an external cooling circulating pipe line. The utility model adopts the technique of evacuating in the die assembly, abandons the mode of drilling air cavities on the die assembly, makes finished products with no air holes, makes the die assembly not deform and break easily, and increases the service life of the die assembly, simultaneously, as adopting the circulating cooling mode in the die assembly, the die assembly structure has good stability and circulating use of water, reduces the use of water, thereby saving manufacturing cost.

Description

A kind of mould structure

Technical field

The utility model relates to a kind of mould, the mould structure that vacuumizes in specifically a kind of mould.

Background technology

In the existing mould, be subjected to the resistance of gas in order to eliminate EVA (ethene-acetate ethylene copolymer) material foaming displacement after the thermal expansion, adopted the mode in hole of on mould, inflating, though solved the resistance of gas, but because the existence of pore makes the product after the moulding that in kind the existence be arranged in appearance, influenced the attractive in appearance of finished product, portioned product is also bad because of exhaust, moulding not exclusively becomes waste product, and production efficiency is lower; In addition, after mould uses a period of time, also can occur filling in dead pore and need inflate the situation in hole again,, cause die deformation easily and break, shorten the service life of mould because the pore that mould is beaten is many.After formed product is finished, generally mold shell is washed by water to cool off and make the finished product typing with normal-temperature water, the cooling owing to outside mould, wash by water, can be subjected to the influence of air themperature and water temperature, product approval effect instability is a mould outwash water cooling mode owing to what adopt simultaneously, and water can not be reused, caused a large amount of consumption of water, also there has been certain unfavorable factor in environment protection emission.

The utility model content

The technical problems to be solved in the utility model provides the mould structure that vacuumizes in a kind of mould.

In order to solve the problems of the technologies described above, the utility model by the following technical solutions:

A kind of mould structure, comprise upper die and lower die, this patrix comprises the loam cake cover plate and contains the loam cake of interior benevolence, this counterdie comprises lower cover and lower cover cover plate, be formed with the die cavity that holds sole between lower cover and the interior benevolence, all offer cooling pipe in the described upper die and lower die, cooling pipe is communicated with the external refrigeration circulation line.

As the improvement to such scheme, the cooling pipe in the upper die and lower die is connected mutually and is communicated with the external refrigeration circulation line.And cooling pipe is the S font and is distributed in the upper die and lower die.In upper die and lower die, also be provided with the cooling slotted eye that is used to connect external refrigeration circulation line and cooling pipe.

As further improvement of these options, also offer the vacuum hole that is communicated with die cavity at upper die and lower die.

The utility model has adopted the technology that vacuumizes in mould, given up the mode in hole of inflating on mould, not only makes the calm hole of finished product, does not also make mould yielding and break, and has increased the service life of mould; Simultaneously, owing to adopt hydronic mode in mould, good stability, water can be recycled, and has reduced water, has saved production cost.

Description of drawings

Accompanying drawing 1 is the utility model cross-sectional view; Accompanying drawing 2 is the structural representation of the upper and lower mould front view of the utility model.

The specific embodiment

For the ease of those skilled in the art's understanding, structural principle of the present utility model is further described below in conjunction with the drawings and specific embodiments:

Shown in accompanying drawing 1,2, this programme disclose a kind of in mould, vacuumize and mould in the mould structure that cools off.

This programme comprises patrix 2, counterdie 3, this patrix comprises loam cake cover plate 22 and contains the loam cake 21 of interior benevolence 24, counterdie 3 comprises lower cover 31 and lower cover cover plate 32, also be fixed with handle 4 on described loam cake cover plate 22 and the lower cover cover plate 32, handle 4 is used for mould is fixed on the work board, at patrix 2, all offer cooling pipe 7 in the counterdie 3, cooling pipe 7 is communicated with the external refrigeration circulation line, be formed with the die cavity 8 that holds sole between lower cover 31 and the interior benevolence 24, when mould heat be heated after, the technology matched moulds moulding that employing vacuumizes in mould, make EVA (ethene-acetate ethylene copolymer) material foaming back displacement after the thermal expansion not be subjected to the resistance of gas, give up the mode in hole of on mould, inflating fully, make the calm hole of footwear mould of moulding, embodied attractive in appearancely, also increased service life of mould.

Cooling pipe 7 in patrix 2, the counterdie 3 series connection mutually is communicated with the external refrigeration circulation line.In order to quicken cooling velocity, cooling pipe 7 is the S font and is distributed in patrix 2, the counterdie 3.In patrix 2, counterdie 3, also be provided with the cooling slotted eye 6 that is used to connect external refrigeration circulation line and cooling pipe 7.Cooling water is entered in the cooling pipe 7 through cooling slotted eye 6 by the external refrigeration circulation line patrix 2, counterdie 3 is cooled off, water through patrix 2, counterdie 3 enters cool cycles utilization once more in the external refrigeration circulation line again, saved water, reduce production cost, also improved production efficiency.

Simultaneously, also offer the vacuum hole 5 that is communicated with die cavity 8 at patrix 2, counterdie 3.

In addition, the utility model not only is used for the production of footwear mould, also can be used for producing physical culture protective articles such as knee-pad, handguard wrist.

The foregoing description is the preferable implementation of the utility model; in addition; all right other implementations of the utility model need to prove that any conspicuous replacement is all within the utility model protection domain under the prerequisite that does not break away from the present utility model design.
