Abstract

The utility model discloses a symmetric runner device of a rubber injection mold. The device comprises an injection mold body (1), wherein a plurality of mold cavities (2) are formed in the injection mold body (1); rubber injection ducts (3) are correspondingly and vertically arranged on each mold cavity (2) and are symmetrically arranged on the two sides of each mold cavity (2); a liquid storage groove (4) is formed in the central position of the upper surface of the injection mold body (1) and is communicated with the rubber injection ducts (3) arranged on the mold cavities (2) via runners (5); and the range of the diameter ratio of the runners (5) to the rubber injection ducts (3) is (1: 1) to (1: 1.5). The device effectively solves the problems that scrap edges are produced and the raw materials are wasted in the product production process due to design defects of runners of traditional rubber injection molds, thus increasing the production costs of enterprises.

Description

A kind of Rubber Injection Mold balance runner device
Technical field
The utility model relates to machining apparatus technical field, is specifically related to a kind of Rubber Injection Mold balance runner device.
Background technology
Along with industrialized development, Die Industry has also obtained fast promoting, and mould is as being used for the instrument of formed article, and this instrument has various parts to form, and different moulds consists of different parts.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.In stamping-out, shaping and punching, die forging, cold-heading, extruding, metallic sintered products compacting, compression casting; and in the compression moulding of goods such as engineering plastics, rubber, pottery or the shaping of injection moulding processing; the instrument that has the product of given shape and size in order to make under external force blank become; at present; rubber enterprise is in mould production process; problem due to mold runner design; conventionally can produce a large amount of slitter edges; cause the waste of raw material; and in die cavity, the injection of rubber liquid is inhomogeneous, causes injecting products variable thickness.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of Rubber Injection Mold balance runner device, the utility model not only efficiently solves traditional rubber injection mold due to runner design defect, cause product in process of production, produce slitter edge, waste raw material, thereby the problem that causes enterprise's production cost to increase, and it is inhomogeneous to efficiently solve the interior rubber liquid injection of traditional moulds die cavity, cause injecting products thickness to differ, affect product quality problem.
The utility model is achieved through the following technical solutions:
A kind of Rubber Injection Mold balance runner device, it is characterized in that: comprise injection mould body (1), in injection mould body (1), be provided with a plurality of die cavitys (2), each die cavity (2) all correspondence is vertically installed with injecting glue duct (3), injecting glue duct (3) is symmetricly set in die cavity (2) both sides, injection mould body (1) upper surface center is provided with liquid storage groove (4), liquid storage groove (4) is connected by the upper injecting glue duct (3) arranging of runner (5) and die cavity (2), the diameter of runner (5) diameter and injecting glue duct (3) is 1:1~1:1.5 than scope.
The further improvement project of the utility model is:
It is starting point that described runner (5) be take liquid storage groove (4), to injecting glue duct (3), is terminal, and runner (5) degree of depth from light to dark.
Compared with prior art, there is following advantage in the utility model:
One, the utility model is by adjusting the ratio of flow diameter and injecting glue channel diameter, can reduce runner in rubber injection process and occur flash, thereby reduce the waste of rubber raw materials, flow channel depth from light to dark, can make the rubber liquid in runner, farthest flow into each die cavity, further improved the utilization rate of rubber raw materials.
Two, each die cavity bilateral symmetry of the present utility model is provided with two injecting glue ducts, and die cavity pressure at both sides is balanced, and it is comparatively even that rubber fluid enters die cavity, and injecting products thickness is even.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises injection mould body 1, in injection mould body 1, be provided with a plurality of die cavitys 2, the equal correspondence of each die cavity 2 is vertically installed with injecting glue duct 3, injecting glue duct 3 is symmetricly set in die cavity 2 both sides, injection mould body 1 upper surface center is provided with liquid storage groove 4, and liquid storage groove 4 is connected with the injecting glue duct 3 arranging on die cavity 2 by runner 5, and runner 5 diameters are 1:1~1:1.5 with the diameter in injecting glue duct 3 than scope; Runner 5 be take liquid storage groove 4 as starting point, and to injecting glue duct, 3 is terminal, and runner 5 degree of depth from light to dark.
In sum, the utility model has reached foregoing invention object.

Claims (2)
