Description
Technical field
The utility model is related to the technical field of injection mold, especially a kind of injection molding machine runners suitable for small pieces
Structure, more particularly to its mechanical connecting structure.
Background technology
With the development of modern industry, plastic products substitution iron and steel parts are more and more, and the technology of mold also constantly pushes away
It is old go out it is new, be also to rack one's brains to update new Tool and Die Technology on improving plastic material utilization rate.
There is class product itself volume very little, there are no raw material weight weight, wastage of material in mold runner for single product weight
It is very serious, but after runner is shortened, cause flow velocity too fast, cause pipeline internal pressure larger.
Invention content
The purpose of this utility model is to provide a kind of injection molding machine flow passage structures suitable for small pieces, effectively shorten
The length of runner passes through and improves runner inner wall structure and realize unhurried current.Overcome shortcoming and defect existing in the prior art.
To achieve the goals above, the technical solution of the utility model is：A kind of injection molding machine stream suitable for small pieces
The top of road structure, including cope plate and lower template, cope plate is equipped with one piece of positioning pressuring plate, and locating ring is equipped at positioning pressuring plate,
The lower part of cope plate is embedded with one piece of upper internal model, and the top of lower template is embedded with one piece of core insert, upper internal model with above and below core insert
Runner mouth to lower recess is formed at corresponding matching, the top of upper internal model, and the inner cavity of the runner mouth is in inverted cone-shaped, runner mouth lower end
Upper internal model in be equipped with the sprue of a genesis analysis, sprue inner cavity is in coniform, and internal diameter is smaller at the upper end of sprue,
Internal diameter is more than internal diameter at upper end at the lower end of sprue, and the lower end of sprue is equipped with a straight tube, the lower end of sprue and straight tube
Middle section is connected to, and four upper forming cavities are respectively equipped at upper internal model lower surface, be respectively equipped at core insert upper surface four with it is upper
The lower forming cavity of forming cavity cooperation, upper forming cavity are spliced into a complete forming cavity up and down with lower forming cavity, and straight tube is close to two
The both sides at end are respectively equipped with a connector, and each connector connects a forming cavity, and straight tube is connected to by connector with forming cavity, mainstream
The ratio of road cavity volume and forming cavity cavity volume is 1:1, spiral groove is formed from top to bottom on cavity wall in sprue.
The utility model discloses a kind of injection molding machine flow passage structures suitable for small pieces, shorten the length of mold sprue
Degree, eliminates traditional moulds cumbersome glue-feeding system and its component, reduces the waste of raw material.So that mould structure is simpler
Change, is conducive to maintenance, effectively improves safety and the practicability of die apparatus.

The utility model discloses a kind of injection molding machine flow passage structures suitable for small pieces, are different from the prior art
In：Including cope plate 1 and lower template 2, the top of cope plate 1 is equipped with one piece of positioning pressuring plate 3, and locating ring is equipped at positioning pressuring plate 3
4, the lower part of cope plate 1 is embedded with one piece of upper internal model 5, and the top of lower template 2 is embedded with one piece of core insert 6, upper internal model 5 with it is lower interior
Runner mouth 7 to lower recess is formed at about 6 corresponding matching of mould, the top of upper internal model 5, and the inner cavity of the runner mouth 7 is in inverted cone-shaped,
Be equipped with the sprue 8 of a genesis analysis in the upper internal model 5 of 7 lower end of runner mouth, 8 inner cavity of sprue in coniform, sprue 8
Internal diameter is smaller at upper end, and internal diameter is more than internal diameter at upper end at the lower end of sprue 8, and the lower end of sprue 8 is equipped with a straight tube 9,
The lower end of sprue 8 is connected to 9 middle section of straight tube, is respectively equipped with four upper forming cavities at 5 lower surface of upper internal model, on core insert 6
Be respectively equipped with four lower forming cavities coordinated with upper forming cavity at surface, upper forming cavity and lower forming cavity be spliced into up and down one it is complete
Whole forming cavity 10, straight tube 9 are respectively equipped with a connector 11 by the both sides of two close end, and each connector 11 connects a forming cavity
10, straight tube 9 is connected to by connector 11 with forming cavity 10, and the ratio of 8 cavity volume of sprue and 10 cavity volume of forming cavity is 1:
1, spiral groove is formed from top to bottom on cavity wall in sprue 8, and the width of groove body narrows from top to bottom, can effectively control stream
Speed.
