Abstract

The utility model discloses a novel die. The novel die comprises an upper die and a lower die, wherein the upper die and the lower die respectively comprise a template and a cover plate, wherein the template and the cover plate are internally provided with a cold and hot pipe in casting molding respectively, a water inlet and a water outlet used for being communicated with the cold and hot pipe are arranged on one sides of the front surfaces of the template and the cover plate respectively, the cold and hot pipe is arranged bending in the template and does not keep horizontal with the template, one template comprises a sealing ring and a vacuum pumping pipe, the sealing ring is arranged on the peripheral contact surface between the two groups of template, the vacuum pumping pipe is communicated with a combination space of the two groups of template. According to the novel die, as the cold and hot pipe in casting molding and the vacuum pumping pipe are adopted, the service life of the die is prolonged; the height design of the curved surface of the cold and hot pipe satisfies the requirement of uniform heating or cooling of the dies with different thicknesses; due to the whole loop type design of the cold and hot pipe, the energy consumption is fully and effectively utilized; due to the reasonable combination design of the vacuum pumping pipe and a sealing pipe, the air resistance applied to the EVA (Ethylen/Vinyl Acetate) in the foaming process is reduced and lowered, and a product is easy to form.

Description

A kind of novel die

Technical field

The utility model relates to technical field of mold, relates in particular to a kind of novel die.

Background technology

In the existing mould for the production of sole, in order to eliminate EVA(ethylene-vinyl acetate copolymer after thermal expansion) material foaming displacement and be subject to the resistance of gas, adopted the mode in hole of inflating on mould, although solved the resistance of gas, due to the existence of pore, made the product after moulding have in appearance in kind existence, affect the attractive in appearance of finished product, portioned product is also bad because of exhaust, and moulding not exclusively becomes waste product, and production efficiency is lower; In addition, use after a period of time at mould, also there will be the dead pore of plug and need to again inflate the situation in hole, the pore of beating due to mould is many, easily causes die deformation and breaks, and has shortened the service life of mould.The moulding of product need mold heated to Celsius 150 ° above and be cooled to Celsius below 20 °, generally transfer heat to mould by heat-conducting plate and make its heating, the thickness of mould has affected the time of heating greatly, and heating is by external heat, easily occurs the problem that heating is inhomogeneous.Cooling general with normal-temperature water shower mold shell, but owing to being subject to the impact of air themperature and water temperature, cool time is long, product approval effect is unstable, and water can not recycle, and cost is high, efficiency is low, and environment protection emission is also existed to certain unfavorable factor.

In order to solve the problems of the technologies described above, the patent No. is that 201320342020.8 Chinese utility model patents disclose a kind of mould, adopts and heats cooling mode at mould inside, and take the mode vacuumizing to carry out matched moulds production.But this patented technology only adopts internal pipeline to realize cooling and heating, by the independently multiple water inlets of U-shaped pipe design configurations and delivery port, must organize the auxiliary realization of cold and hot energy supply equipment more, greatly increase energy consumption, especially in the time that mold cavity position thickness is excessive, its internal pipeline is every too far away, and cold and hot conduction must be obstructed, impact heating and cooling effect.

Summary of the invention

Especially, described template comprises lower bolster and cope match-plate pattern, hot and cold tube distributing position in described cope match-plate pattern and described template keep low early and high after ramp type to distribute, and before the hot and cold tube distributing position in described lower bolster and described template keep, high rear low ramp type distributes.

Especially, described cover plate comprises upper cover plate and lower cover, and described upper cover plate and lower cover are respectively with described cope match-plate pattern and lower bolster is detachable is connected.

Especially, on described lower bolster, also comprise that one vacuumizes hole, described in vacuumize hole and be communicated with described vacuum-pumping tube.

Especially, the water inlet in described template and delivery port are arranged on the left and right sides or the positive two ends of described cover plate.

Especially, hot and cold tube in described cover plate and template is separate respectively, and described hot and cold tube is return passage independently.

The beneficial effects of the utility model: the novel die that the utility model provides adopts hot and cold tube and the vacuum-pumping tube of the moulding of casting, extend the service life of mould, the curved surface height design of hot and cold tube meets the mould homogeneous heating of different-thickness or cooling, the bulk loop formula design of hot and cold tube, reduce the use of function auxiliary equipment, fully effectively utilize energy consumption, reasonably vacuum-pumping tube and the design of sealed tube combined type, reduce and reduce the air drag being subject in EVA foaming process, be easy to formed product, independently vacuumize hole and connect back-shaped vacuum-pumping tube, simple in structure, effect is remarkable.

Below in conjunction with accompanying drawing, the utility model is elaborated.
