Description
Technical field
The present invention relates to mould applications, specifically, plastics suction mould is just being used in the back suction that specially refers to a kind of modified form.
Background technology
The various tool and the product that are used in daily production, the life arrive base, the fuselage cover of lathe greatly, and little shell to embryo head screw, button and various household electrical appliance has confidential relation with mould invariably.The shape of mould is determining the profile of these products, and the crudy of mould and precision are also just determining the quality of these products.Because the difference of the material of various products, outward appearance, specification and purposes, mould are divided into non-plastic moulds such as casting die, forge mould, compression mod, stamping die, and plastic mould.
Along with engineering plastics the improving constantly of aspects such as intensity and precision, the range of application of plastic products is also in continuous expansion, the shared ratio of plastic products just rapidly increases.A working of plastics reasonable in design often can replace a plurality of traditional metal parts.Along with the consumption of plastic product constantly rises the also corresponding continuous growth of the application of plastic mould.According to the difference of forming method, mould of plastics mainly contains injecting molding die, extrusion molding mould, plastics sucking moulding mould, highly foamed polystyrene mould etc.
What cost was minimum in the plastics suction mould is plaster mold, secondly is to electroplate copper mold, and the most expensive is aluminum dipping form.The plastics suction mould structure is comparatively simple, uses very extensive.But general pressure is lower during the plastics suction mould moulding, because too high suction can cause the product surface out-of-flatness, even in drawing process, inhales bad product, so general plastic uptake product can only be accomplished the 50mm degree of depth.
In addition, thermoplastic plastic plate, sheet material general temperature after the production line transmission is on the low side, and existing plastics suction mould can not carry out the temperature heating to plastic plate, sheet material, and plastic plate, sheet material and plastics suction mould contact the back and further reduce temperature, thereby are unfavorable for stretching; To the plastic product of back-off is arranged, temperature is on the low side after the moulding is not easy the demoulding.Therefore, be necessary existing plastics suction mould structure is improved, stretched sheet improves product surface smoothness and product yield better.
Summary of the invention
The object of the present invention is to provide a kind of back suction of modified form just using plastics suction mould,, overcome the deficiency in the conventional art, thereby realize the object of the invention through the improvement of structure is just being carried out in traditional back suction with plastics suction mould.
The technical problem that the present invention solved can adopt following technical scheme to realize:

Said punch structure is provided with some row, and on the parallel base plate that is distributed in die holder, said punch structure comprises projection, boss and connecting portion; Said projection is arranged at the two ends of punch structure; The outside of projection is pressed close to the side plate of base plate and is left the gap, evenly is provided with some boss between the said projection, all links to each other through connecting portion between projection and boss and boss and the boss; The cross section of said connecting portion one end is trapezoidal; The cross section of the connecting portion other end is " T " shape, and a side of two adjacent connecting portions constitutes trapezoidal, and opposite side constitutes inverse-T-shaped; Said projection, boss and connecting portion are equipped with aperture, are used for the hard sheet of vacuum suction thermalization.
In one embodiment of the invention, said die main body is an aluminum dipping form.
In one embodiment of the invention, said first side plate and the 3rd side plate are provided with three convexities, and second side plate and the 4th side plate are installed and be provided with two convexities.
In one embodiment of the invention, the cross section of said convexity is " L " shape, and protruding height longitudinally is less than horizontal length.
In one embodiment of the invention, the other end of said connecting portion is provided with boss structure.
In one embodiment of the invention, said punch structure is provided with 8 row, and every row punch structure comprises 2 projections, 7 boss and 8 connecting portions.
Beneficial effect of the present invention is: improves the smoothness and the product percent of pass of product surface, reduced cost, simultaneously aborning can better stretched sheet, and improve the smoothness and the product percent of pass of product surface, also convenient follow-up stripping operation.
Description of drawings
Fig. 1 is just using the structural representation of plastics suction mould for the back suction of a kind of modified form of the present invention.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with the specific embodiment, further set forth the present invention.
