Description

A kind of mould of remote control push-and-pull lid

Technical field

Injection mold technology is the utility model is related to, is to be related to a kind of mould of remote control push-and-pull lid specifically.

Background technology

The injection molding of plastic cement products is typically that the sizing material of melting is in product by the plastic injection of melting into mold cavity Plastic cement products are cooled into die cavity, while the sizing material melted cooled and solidified in sizing material passage forms gate waste, reaches top After going out temperature, mold open, plastic cement products and gate waste are taken out, so as to be prepared for injection next time.In process of setting In, gate waste and de- material passage have a certain degree of adhesion, in ejection process gate waste need under force with mould Tool departs from.

As shown in figure 1, the ox horn of existing injection mold, which enters plastic structure 1, includes two arcs of two arc bends 11 and connection The interconnecting part 12 of shape bend 11, interconnecting part 12 be in smooth outer surface column, such ox horn ejection when, ejection part 13 by On thrust after the flexural deformation of interconnecting part 12, due to there is no radian, interconnecting part 12 between ejection part 13 and two arc bends 11 Flexural deformation is not easy, if ox horn leaves mould after further increasing thrust, now, the adhesion pulling force that arc bend 11 is subject to is unexpected Disappearance, the very fast motion upwards of end 111 of arc bend 11, bullet wound product after being contacted with shaped article, ox horn enter plastic structure 1 The action process is referred to as slingshot effect.Because shaped article is plastic cement products, slingshot effect easily damages product, reduces product Qualification rate, while the waste of raw material is caused, increase production cost.

The content of the invention

The purpose of this utility model is to provide a kind of mould of remote control push-and-pull lid, and the mould produces when runner can be avoided to eject Raw slingshot effect and bullet wound product, and enter glue position and do not need secondary operation, be will not leave behind on formed product surface into glue vestige.

To realize such scheme, the utility model provides a kind of mould of remote control push-and-pull lid, including from top to bottom successively Panel, front template and the rear pattern plate of setting, be inlaid with front cavity in front template, be inlaid with rear cavity in rear pattern plate, front cavity and Two interconnected product die cavities, the shape and the shape phase of remote control push-and-pull lid of product die cavity are provided between rear cavity Together；Rear mold insert group is inlaid with rear cavity, rear mold insert group includes the first rear mold insert being oppositely arranged and the second rear mold edge The inside of block, the first rear mold insert and the second rear mold insert surrounds an ox horn and enters plastic structure；The mould of remote control push-and-pull lid is also Including nozzle mouth, nozzle mouth, which sequentially passes through panel, front template and front cavity and enters plastic structure with ox horn, to be connected, and the center of nozzle mouth is opened Provided with runner；Ox horn, which enters plastic structure, includes two symmetrically arranged arc bends, and the first end of arc bend is provided with sharp mouth, Sharp mouth stretches into product type intracavitary, and the second end of two arc bends is connected by interconnecting part, and the Part I of interconnecting part is set Put in rear mold insert group, the Part II of interconnecting part is arranged in front cavity, interconnecting part and flow passage；Ox horn enters plastic structure Lower central opening position be provided with mouth of a river thimble, mouth of a river thimble abuts with interconnecting part, interconnecting part filling pipe end thimble and curved bend The wave point to raise up is provided between road.

One preferable scheme is that the longitudinal section of wave point is arc.

Further preferred scheme is that the longitudinal section of wave point is semicircle.

Scheme still more preferably is that the mould of remote control push-and-pull lid also includes oblique top and tilted footstock, each product type Chamber sets two oblique tops, and the first end of oblique top stretches into product die cavity, and the second end of oblique top is arranged on tilted footstock, the top of oblique top With the shape with being engaged on the inside of remote control push-and-pull lid.

Scheme still further preferably is that fixed plate is arranged with oblique top, and rear pattern plate bottom offers mounting groove, fixed plate It is arranged on by fixture in mounting groove.

Further preferred scheme is that I-shaped groove is offered on tilted footstock, and the second end of oblique top is provided with shoes, shoes with I-shaped groove has the shape being engaged, and shoes is arranged in I-shaped groove, and can be slided in I-shaped groove.

One preferable scheme is that sharp mouth has external port and inner port, straight from inner port to external port point mouth Footpath is gradually reduced.

From such scheme, improve existing ox horn and enter plastic structure, interconnecting part filling pipe end thimble and arc bend it Between the wave point to raise up is set, make ox horn in ejection process be easier deform, ox horn be easier enter from ox horn in plastic structure Depart from, slingshot effect and bullet wound product are produced in ejection so as to avoid ox horn and runner, it is cementing additionally by ox horn is entered The sharp mouth of structure is deep into the inside of product die cavity, and the injecting products raw material in ox horn runner can be made to be flowed directly into by sharp mouth Product type intracavitary is molded, and sharp mouth directly contacts with remote control push-and-pull lid product, during the demoulding and remote control push-and-pull lid product It is automatically separated, it is not necessary to artificial cut cuts processing, so that it is guaranteed that the overall appearance of injecting products, and labor intensity can be reduced.
