Abstract

The utility model provides an advance glued structure, includes: advance the solation way, be located advance the gluey runner of solation way end and mould cavity UNICOM, it is the crotch form to advance gluey runner to in mould cavity lateral wall department with die cavity UNICOM. The utility model discloses the advance glued structure who provides, through will advancing gluey gating design for crotch form, by mould side and die cavity UNICOM, can prevent the suburbs effectively after, there is remaining gluey wave point that advances in the product surface, makes that product shaping rear surface is smooth to be leveled, adopt the design that the solation said that scattering shape distributed, can prevent that the subchannel accident from falling into the mould in, cause moulding -die harm mould.

Description

One kind enters plastic structure

Technical field

The application is related to a kind of injection mold, enters plastic structure in more particularly, to a kind of mould.

Background technology

Traditional injection mold, as Figure 1-Figure 4, mainly includes sprue 1 and is located at sprue 1 both sides and master respectively Some sub-runners 2 of runner 1 UNICOM, it enters glue runner 1 and generally enters glue using straight-down negative, and after entering cementing bundle, product 3 surface corresponds to The problem destroying product surface smoothness into glue wave point 4 can be formed at cast gate.

Content of the invention

This utility model provide one kind to enter plastic structure it is intended to solve existing injection mold enter product surface after glue pure in residual Suburbs wave point, destroy product surface smoothness problem.

One kind enters plastic structure, including：Enter glue runner, positioned at described enter glue flow field end and mold cavity UNICOM the glue that enters pour Mouthful, described enter glue cast gate be in hook solid, and in mold cavity side-walls and described die cavity UNICOM.

Described enters plastic structure, wherein, described enter glue runner radially distribute, be provided with positioned at radial center junction Liquid injection port.

Enter plastic structure given by this utility model, be hook solid by glue gate design will be entered, by mould side and type Chamber UNICOM, after being effectively prevented the suburbs, what product surface presence remained enters glue wave point, and after making formed product, smooth surface is put down Whole；Using the design entering the distribution of glue runner dispersion shape, can prevent sub-runner from surprisingly falling in mould, cause pressing mold infringement mould Tool.

Specific embodiment

Combine accompanying drawing below by specific embodiment the application is described in further detail.

What the present embodiment was provided enters plastic structure, as shown in Figure 5 and 7, enters glue runner 5 including radially distribute, It is located at into glue runner 5 end and the cast gate 7 with mold cavity UNICOM.Enter the radial center of glue runner 5 and be provided with liquid injection port 6.As shown in FIG. 6 and 7, cast gate 7 be in hook solid, its top with enter glue runner 5 end UNICOM, the side by mold cavity for the end Wall 8 and die cavity UNICOM.

Using this kind of design, during injection, solution is injected by liquid injection port 6, and by entering glue runner 5 inflow, each enters at glue point Cast gate 7, solution enters in die cavity by cast gate 7 by side wall 8, so avoids to stay into glue wave point in product surface, makes Obtain product surface smooth.

Additionally, existing enter plastic structure, as shown in Fig. 1 and Fig. 4, because sub-runner 2 is arranged at sprue both sides, sub-runner 2 junction points are less, are easier to fall in mould, lead to pressing mold mold damage.And in the present embodiment, enter glue runner 5 radial Distribution, the centre position that it interacts is communicating together, and increase power a little so as to enter glue runner 5 more firm, will not fall into mould In, it is to avoid mold damage.

Above content is further description the application made with reference to specific embodiment it is impossible to assert this Shen Being embodied as please is confined to these explanations.For the application person of an ordinary skill in the technical field, do not taking off On the premise of the present application design, some simple deduction or replace can also be made.

Claims

1. one kind enters plastic structure it is characterised in that including：Enter glue runner, positioned at described enter glue flow field end and mold cavity join Logical enter glue cast gate, described enter glue cast gate be in hook solid, and in mold cavity side-walls and described die cavity UNICOM.

2. enter plastic structure as claimed in claim 1 it is characterised in that described enter glue runner radially distribute, positioned at radiation Shape center junction is provided with liquid injection port.
