Description

Thin wall product processing is with preventing protection mould that splits

Technical Field

The utility model discloses a relate to injection mold technical field especially relates to a thin wall product processing is with preventing protection mould that splits.

Background

When a thin-wall product is subjected to injection molding, if a porous plastic product exists, fluid enters a cavity from a pouring gate and converges at the tail end of the cavity, and because the fluid is divided when entering the cavity, a weld mark is formed at the intersection of two plastic strands at the tail end of the cavity, and because of the weld mark, the product has poor strength at the joint, is easy to break and cannot bear normal working load. Meanwhile, in the injection molding process, the injection speed is too high, the cooling time of the plastic part is controlled improperly, so that the local temperature is uneven, the mold exhaust system is poor, bubbles are formed inside the product due to the fact that gas is not discharged timely and the like, the strength of the product is greatly reduced due to the existence of the bubbles, a user cannot be satisfied, and the cost is greatly wasted.

Through the above analysis, the problems and defects of the prior art are as follows: the existing thin-wall product forms a weld mark during injection molding, so that the product has poor strength at a joint and is easy to break and cannot bear normal working load.

the inside integration of moulding mould is provided with the moulding chamber, it has the passageway to run through inside the mould to push up, the joint of mould upper portion has the inlet pipe.

In one embodiment, a flash cavity is integrally formed in the bottom die, and air holes are formed in the lower side of the bottom die and communicated with the flash cavity.

In one embodiment, the top die channel is communicated with the inlet of the top of the shaping cavity, and the outlet of the feeding pipe is fixedly connected with the inlet of the channel.

In one embodiment, the flash chamber inlet is fixedly connected to the fluid junction in the shaping chamber.

In one embodiment, the plastic-shaped cavity is a vented cavity.

In one embodiment, the top mold, the shaping mold and the bottom mold are silicone molds.

The utility model discloses a technical scheme that embodiment provided can include following beneficial effect:

first, the utility model discloses a set up the flash chamber, can make the fluid converge at the flash intracavity, prevent that the product from appearing dissolving and connect the trace to improve the intensity of porose product, avoided the easy cracked problem of porose product.

Secondly, silica gel is used as a top die, a shaping die and a bottom die, so that the product is easy to demould after being formed, and the production cost is low; the air holes can discharge air in the fluid, further increasing the strength of the product and reducing the waste of materials.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.
