Description

A kind of braking automobile braking rubbery membrana dermalis mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of braking automobile braking rubbery membrana dermalis mould.

Background technology

Usually the design of die joint will directly influence the complexity and the manufacturing cost of mould, and the quality of product is exerted an influence.As the big complicated thin-walled class rubber part of size, at first, the appropriate design of die joint is particularly important: similar mould is initially two plate structures, depth of cavity is dark and the groove of back-off occurred, and the utmost point is unfavorable for processing, and mould is in knockout course, occur cracking easily, cause product rejection; Secondly, lack center guide pillar, and guide pillar does not have corresponding guide pin bushing all around, monolateral phenomenon will appear in product like this; Do not have air discharge duct in the structure, product is prone to mashed bubble phenomenon; The nothing left hopper, the product overlap is thicker; Non-trimming UNICOM groove, mould deflashing efficient is low; Torn edges slot pitch die cavity is far away excessively, the product of producing, and then need the artificial manual scissors that uses to remove rubber component product slitter edge, the a large amount of artificial scissors that use of this needs go the way of rubber component product slitter edge to enhance productivity, because causing product to exist, manual work mode do not eliminate clean slitter edge, product easily by quality problems such as sharp instrument scuffing such as scissors yet, not only do not reach the torn edges effect, also can cause product quality to descend; In addition, consider from client's angle, will cause the braking automobile brake failure, personal safety can not get ensureing.

The utility model content

At above defective, the braking automobile braking rubbery membrana dermalis mould that the purpose of this utility model provides a kind of processing that makes the production qualification rate improve, be convenient to mold cavity greatly, torn edges is respond well, steel hardness is higher, anti-corrosion and heat conductivility is preferable, can increase the service life is to solve many deficiencies of prior art.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of braking automobile braking rubbery membrana dermalis mould, comprise cope match-plate pattern, middle template, lower bolster, adopt bolt respectively with cope match-plate pattern, lower bolster, two fixedly backing plate be assembled into the whole upper and lower mould that forms, template and lower bolster are connected in described, described lower bolster middle part edge is joined lower mold core one, joins lower mold core two with the lower bolster edge of lower mold core one adjacent position; Its cope match-plate pattern middle part is respectively equipped with center guide pin bushing and guide pillar two with an end, and its lower bolster middle part is respectively equipped with center guide pillar and guide pillar one with an end, and this center guide pillar is connected with center guide pin bushing secure fit; Wherein the template two ends are respectively equipped with guide pin bushing one and guide pin bushing two and are connected with set guide pillar one, the guide pillar of all the other two templates respectively.The outside of described cope match-plate pattern and lower bolster respectively is provided with a fixing backing plate, adopts 20 ° of gradients to cooperate between described cope match-plate pattern and the lower bolster and is connected.

The beneficial effect of braking automobile described in the utility model braking rubbery membrana dermalis mould is: appearance looks elegant, dimensionally stable, bad defective are few, improved product percent of pass greatly, and help die cavity processing, help taking numerical control car, numerical control to mill the processing mode of combination, improve the service life of mould.Mainly show as:

(1) mould adopts three plate structures, is divided into the upper, middle and lower mould, and counterdie wherein adopts core rod edge allotment of labor skill, has made things convenient for the processing of mold cavity;

(2) design torn edges groove, air discharge duct, surplus glue groove, overlap UNICOM groove apart from the die cavity appropriate location on the mould die joint, the effect of torn edges groove is to improve road, back arrangement efficient, reduction cost of human resources, makes product appearance attractive in appearance; The effect of air discharge duct is the air in the mould when discharging matched moulds, prevents that mashed bubble phenomenon from appearring in product; The effect of surplus glue groove is the unnecessary sizing material of shunting, makes the product overlap thinner; The effect of overlap UNICOM groove is that torn edges groove and overlap are coupled together, and purpose is to have improved the efficient of removing overlap;

(3) adopt center guide pillar, guide pin bushing between the mould of upper, middle and lower and several guide pillars, the guide pin bushing that are positioned at around the template position, the location is accurate like this, and product is difficult for monolateral; Guide pillar, the complete use of guide pin bushing can not cause guide pillar directly to contact with mould and cause die wear;

(4) some back-off position of model cavity is not adopted spark machined but is adopted the moulding cutter to process, because the mold cavity surface roughness of spark machined is lower, can not satisfy the assembly performance requirement of product; Occur cracking easily in assembling process, cause skidding malfunctioning, consequence is just hardly imaginable;

(5) adopt new die steel, this mould steel hardness height, the polishability performance is good and anti-corrosion thermal conductivity is good;

(6) the mold cavity surface is carried out chromium plating and is handled, like this surface smoothness height, corrosion-resistant, service life of having prolonged mould.
