Abstract

The utility model discloses a kind of anti-wire drawing sprue bush；It is made of sprue bush and anti-wire drawing piece；The sprue bush has sprue, and anti-wire drawing piece is fixedly mounted on the sprue end of sprue bush；The anti-wire drawing on piece offers discharge port, which is connected to the sprue of sprue bush.Since the anti-wire drawing piece of the utility model is fixedly mounted on the sprue end of sprue bush, the discharge port of anti-wire drawing on piece is connected to the sprue of sprue bush, reduce the product wall thickness of sprue end, it is effective to shorten cooling time, so that sprue end, in curdled appearance, wire drawing phenomenon will not be generated in demoulding.

Description

Anti- wire drawing sprue bush

Technical field

The utility model relates to a kind of injection molds, more particularly to a kind of anti-wire drawing sprue bush.

Background technique

Plastics injection mould is the tool for producing plastic products, very widely used.In plastic products injection molding, note It moulds molding product and needs the one-step cooling time before demoulding.As shown in Figure 1A, Figure 1B, traditional sprue bush is in formed product Afterwards, since the product wall thickness B for being located at sprue end 10 is thicker, longer cooling time is needed, wire drawing 101 is otherwise easy to appear Phenomenon.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-wire drawing sprue bush for effectivelying prevent wire drawing phenomenon to generate.

To achieve the above object, the technical solution of the utility model is:

The utility model is a kind of anti-wire drawing sprue bush；It is made of sprue bush and anti-wire drawing piece；The sprue bush has Sprue, anti-wire drawing piece are fixedly mounted on the sprue end of sprue bush；The anti-wire drawing on piece offers discharge port, should go out Material mouth is connected to the sprue of sprue bush.

The discharge port of the anti-wire drawing on piece is in cross.

Deep gouge is offered on the inner face of the sprue bush, which is located at the sprue end of sprue bush；Described Anti- wire drawing piece is fixedly mounted in the deep gouge of sprue bush and the discharge port of anti-wire drawing on piece is connected to the sprue of sprue bush.

After adopting the above scheme, it is made of due to the utility model sprue bush and anti-wire drawing piece, anti-wire drawing piece is fixedly mounted Discharge port in the sprue end of sprue bush, anti-wire drawing on piece is connected to the sprue of sprue bush, reduces sprue end Product wall thickness, it is effective to shorten cooling time, so that sprue end, in curdled appearance, it is existing that wire drawing will not be generated in demoulding As.

The utility model is further described in the following with reference to the drawings and specific embodiments.

Specific embodiment

As shown in Figure 1 and Figure 2, the utility model is a kind of anti-wire drawing sprue bush；It is made of sprue bush 1 and anti-wire drawing piece 2.

The sprue bush 1 has sprue 11, offers deep gouge 12 on the inner face of sprue bush 1, which is located at 11 end of sprue of sprue bush 1.

Discharge port 21 is offered on the anti-wire drawing piece 2, anti-wire drawing piece 2 is fixedly mounted in the deep gouge 12 of sprue bush 1 And the discharge port 21 on anti-wire drawing piece 2 is connected to the sprue 11 of sprue bush 1.In the present embodiment, the discharging on anti-wire drawing piece 2 Mouth 21 is in cross.

Working principle of the utility model is:

As shown in figures 3 to 6, the utility model forms cross by increasing anti-wire drawing piece 2, the end of sprue waste material 20 Shape waste material 201 reduces the wall thickness of 1 sprue of sprue bush, 11 end, i.e. the wall thickness C of sprue waste material 20, effectively shortens cold But the time makes 20 end of sprue waste material, in curdled appearance, will not generate wire drawing phenomenon in demoulding.

The above, only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this Range should still belong to this reality that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description In the range of being covered with new patent.
