Abstract
The utility model discloses a bicolor hot runner mould, which comprises ejector pins, a positioning round pin, a rear mould insert, a rear mould, a guide sleeve, an upper guide post, a front mould, a front mould insert, a hot runner, a gate, a movable mould and an oil cylinder. The bicolor hot runner mould is applicable to generation of bicolor mould products in one hot runner mould by stripping the mould once. After the mould is closed for pouring in use, the mould is opened, runner excess materials in a semi-finished product are ejected, the movable mould rotates for 180 degrees, the mould is closed for pouring again and opened, the left ejector pin and the right ejector pin are used for ejecting the runner excess materials in the semi-finished product and a finished product respectively, and then the mould is closed for processing of a next batch of products. The bicolor hot runner mould is high in automation degree and production efficiency, low in requirements on operators, and simple in processing. Besides, cost is reduced as production batch is large, the produced products are attractive in appearance, waste products are decreased, product quality is improved, plastic raw materials are saved, and subsequent procedures are not needed.
Description
Technical field
The utility model relates to a kind of double-colored hot runner mould, can satisfy a depanning processing request of double-color mold.
Background technology
In the production process of injection-molded item, the current injection mold that uses widely.Mould product in the past is because the technical limitations majority is monochromatic production, promptly can only be with a kind of plastic material injection mo(u)lding, though like this product appearance of Sheng Chaning be material with or color all rich and varied inadequately.Along with era development, people are more and more higher for the appearance requirement of product now, and the mould product of pursuing more exquisite fashion and individual character has become current a kind of trend.
Double-color mold is in vogue day by day in the market, but also has the mould complexity, the shortcoming that processing cost is high.For the die products of two kinds of colors, need to adopt the quadric injection mould of two width of cloth front moulds and a secondary back mould cooperation, adopt post forming, i.e. two kinds of not necessarily injection moulding, moulding at twice on same mould of plastic material; Product after the depanning taking-up, is put into an other mold again and is carried out the injection mo(u)lding second time from a mold.And the injection mold of continuing to use is all a secondary mould and a mold injects mouth matches, and during production, needs through matched moulds, injection, die sinking, gets the production that a plurality of processing steps such as material are finished product.So whole process of production is comparatively complicated, operation is many, and causes mould and die accuracy to reduce.And product or the phenomenon of peeling off loosening from the stop side of mould after the moulding for the first time of double-color mold ubiquity, cause the bad or mould of the product that molds for the second time to weigh wounded.
The hot flow path technology of plastic injection mould, in mould of plastics processing,, get the nod and affirm, and application widely.At prices of raw and semifnished materials straight rise, line operator today in short supply reduce raw materials consumption, realize production mechanization, be the hope that many plastic products processing enterprise is pursued.The hot flow path technology is exactly to realize a shortcut of this hope.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of double-colored hot runner mould is provided.
Double-colored hot runner mould is characterized in that comprising left thimble, back location round pin, left back mould mold insert, back mould, upper guide bush, upper guide post, prelocalization round pin, front mould, front mould mold insert, left hot flow path, goes up cast gate, right hot flow path, right cast gate, cover half, guide pillar, guide pin bushing, dynamic model, right back mould mold insert, right thimble, dynamic mould fixing plate, pull bar, fastener, middle holder limit, middle holder department, location department, thimble supporting plate upper cylinder, following oil cylinder down down; Be provided with left hot flow path in the cover half, right hot flow path, cover half is provided with cast gate and right cast gate, the front mould mold insert matches by bolting in cover half with front mould, cover half cooperates fixing with dynamic model with upper guide bush by upper guide post, and locate by the prelocalization round pin, dynamic model is fixed in dynamic mould fixing plate by descending guide pillar to cooperate with following guide pin bushing, and by back setting circle finger setting, front mould is fixed by bolt and dynamic model, front mould matches with the front mould mold insert, the front mould mold insert is fixed in dynamic mould fixing plate, left side thimble is installed on dynamic mould fixing plate, right thimble is fixed in the thimble supporting plate, the thimble supporting plate cooperates with middle holder department by middle holder limit and is installed on dynamic mould fixing plate, fastener is installed on dynamic mould fixing plate by bolt, upper cylinder is fixed in dynamic mould fixing plate, and be connected with pull bar by flexible pipe, following oil cylinder is fixed in dynamic mould fixing plate, be connected with the thimble supporting plate by flexible pipe, constitute the first look injection moulding die cavity between front mould mold insert and left back mould mold insert, front mould mold insert and right back mould mold insert constitute the second look injection moulding die cavity, and four left thimbles withstand on hot flow path clout position in the first look injection moulding die cavity, and right thimble withstands on finished product position in the second look injection moulding die cavity.
Use the utility model, can reduce the operation of whole double-color mold cast, enhance productivity, owing to divide the mould matched moulds that the accurate localization round pin is all arranged, guaranteed the accuracy of mould finished product, owing to adopted the hot flow path cast, there is not the runner system restriction of cool time, just can in time eject behind the product forming and hardening.Shorten the product molding cycle greatly, entire making process realizes production mechanization, eliminates subsequent handling, reduces waste product, improves the quality of products, and saves plastic raw materials.The utility model can also make the outward appearance of product more beautiful, is easy to change color and can sprays.
