Abstract
A kind of injection mold large injection force cast gate structure-improved, it comprises front cavity (1) and rear cavity (2), it is characterized in that: in described front cavity (1), be provided with front runner (101), rear runner (201) is provided with in described rear cavity (2), described front runner (101) and rear runner (201) are connected in front cavity (1) and rear cavity (2) interface, and described front runner (101) internal diameter is larger than rear runner (201) internal diameter.The utility model under doing simply improved situation to existing mold cast gate, can provide the injection force of cast gate greatly, is conducive to the plastic material flowing under molten condition, is conducive to the shaping of product.
Description
Technical field
The utility model belongs to injection molding technology field, specifically just relates to a kind of injection mold large injection force cast gate structure-improved.
Background technology
Injection molded is a kind of important means of product shaping, injection molded utilizes the plastic material principle that changes of shape at high temperature under high pressure, plastic mould is used various plastic material to be made into the process of the product required for people, in general, plastic mould is for the shaping built-up plastics mould of compression moulding, extrusion molding, injection, blowing and low ratio foamed, it mainly comprises dynamic model, cover half and core rod, and dynamic model and cover half are equipped with die cavity, and die cavity is built with core rod.Existing common plastic mould is all form after injecting plastic mould by injection machine after the melting of plastic cement raw material.
Now commercially the quality of a lot of plastic cement products more and more in, volume is also increasing, but with owing to being limited to the speciality that plastic material flows in the molten state, only ensureing under certain injection pressure condition, plastic material under molten condition just can flow, and therefore, the cast gate of existing injection mold can not be accomplished very large, injection time is caused to extend, the at substantial energy.
Utility model content
The purpose of this utility model is exactly the limited technological deficiency of the injection force that can be formed for existing injection moulding die casting mouth, a kind of injection mold large injection force cast gate structure-improved is provided, can under simply improved situation be done to existing mold cast gate, the injection force of cast gate is provided greatly, be conducive to the plastic material flowing under molten condition, be conducive to the shaping of product.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of injection mold large injection force cast gate structure-improved, it comprises front cavity and rear cavity, it is characterized in that: in described front cavity, be provided with front runner, rear runner is provided with in described rear cavity, described front runner and rear runner are connected in front cavity and rear cavity interface, and described front runner internal diameter is larger than rear runner internal diameter.
Further, one end oral area of described front runner and rear flow passage is step-likely to reduce gradually, and oral area is that taper and rear runner are connected.
Further, described rear runner and front runner are connected one end and are expanded into taper gradually backward.
Beneficial effect
A kind of injection mold large injection force cast gate structure-improved that the utility model provides, under doing simply improved situation to existing mold cast gate, can provide the injection force of cast gate greatly, is conducive to the plastic material flowing under molten condition, is conducive to the shaping of product.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.、
Embodiment
As shown in Figure 1, a kind of injection mold large injection force cast gate structure-improved, it comprises front cavity 1 and rear cavity 2, it is characterized in that: in described front cavity 1, be provided with front runner 101, rear runner 201 is provided with in described rear cavity 2, described front runner 101 and rear runner 201 are connected in front cavity 1 and rear cavity 2 interface, and described front runner 101 internal diameter is larger than rear runner 201 internal diameter.
One end oral area that described front runner 101 is communicated with rear runner 201 is step-likely to reduce gradually, and oral area is that taper and rear runner 201 are connected.
Described rear runner 201 is connected one end with front runner 101 and is expanded into taper gradually backward.
A kind of injection mold large injection force cast gate structure-improved that the utility model provides, under doing simply improved situation to existing mold cast gate, can provide the injection force of cast gate greatly, is conducive to the plastic material flowing under molten condition, is conducive to the shaping of product.
