Abstract

The utility model relates to a kind of constant temperature runner rubber injection mode structure, comprises mutual opposed upper die and lower die, and the top of patrix is provided with the deflector being communicated with patrix, and the top of deflector is provided with controls the temperature-constant plate that sizing material keeps constant temperature.The temperature-constant plate of this constant temperature runner rubber injection mode structure is by the circulation of warm water, the rubber injecting is remained within the scope of stationary temperature, can because of not using for a long time, hardening cause the waste of rubber, overcome high and not high with the mould matching degree defect of traditional cold runner equipment cost; This rubber injection mode structure can be according to the size of mould structure, and appropriate design heater plays energy-conservation effect, low cost of manufacture, and the thermal insulation board being provided with between deflector and patrix, avoids sizing material incipient scorch.

Description

A kind of constant temperature runner rubber injection mode structure
Technical field
The utility model relates to a kind of injection mold structure, especially a kind of constant temperature runner rubber injection mode structure.
Background technology
Rubber mold is divided into press-moulding die, die-casting forming die, injecting molding die and extrusion molding mould etc. according to the difference of mould structure and product producing process, injection molding is mainly that the sizing material that preheats into plastic state is injected to mould first cure through the running gate system of injection mould, existing rubber injecting molding die is all directly by injector, directly the rubber after heating to be injected in the die cavity of mould, after shot technique completes, rubber in injector is not easy to preserve finally as waste disposal, has caused the waste of raw material.In order to overcome the defect of wastage of material, on some moulds, be equipped with cold runner equipment, but cost of investment is very high, and also not high from the outfit degree of different injection moldings yet.
Utility model content
The purpose of this utility model is in order to solve the existing defect of rubber injection mold in prior art, a kind of low cost of manufacture to be provided, and avoids the constant temperature runner rubber injection mode structure of sizing material incipient scorch and waste.
To achieve these goals, the technical solution adopted in the utility model is:
A constant temperature runner rubber injection mode structure, comprises mutual opposed upper die and lower die, and the top of described patrix is provided with the deflector being communicated with patrix, and the top of described deflector is provided with controls the temperature-constant plate that sizing material keeps constant temperature.
Above-mentioned a kind of constant temperature runner rubber injection mode structure, the above and below of described temperature-constant plate is respectively equipped with the glue muzzle He Liuliao road being interconnected, and glue muzzle Yu Liuliao forms sizing material reservoir cavity between road.
Above-mentioned a kind of constant temperature runner rubber injection mode structure, is also provided with passage of heat in described temperature-constant plate, a side of temperature-constant plate is provided with the thermal hole of connecting with passage of heat.
Above-mentioned a kind of constant temperature runner rubber injection mode structure, is provided with thermal insulation board between described deflector and patrix, is equipped with the material guide hole that keeps patrix and constant temperature plate current material road to connect on deflector and thermal insulation board.
Above-mentioned a kind of constant temperature runner rubber injection mode structure, described passage of heat is connected and carries out thermostatted water circulation with extraneous water die heater.
The beneficial effects of the utility model are: the temperature-constant plate of this constant temperature runner rubber injection mode structure is by the circulation of warm water, the rubber injecting is remained within the scope of stationary temperature, can because of not using for a long time, hardening cause the waste of rubber, overcome high and not high with the mould matching degree defect of traditional cold runner equipment cost; This rubber injection mode structure can be according to the size of mould structure, and appropriate design heater plays energy-conservation effect, low cost of manufacture, and the thermal insulation board being provided with between deflector and patrix, avoids sizing material incipient scorch.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For making that the utility model is done further to understand, below with reference to Figure of description and specific embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of constant temperature runner rubber injection mode structure, comprise mutual opposed patrix 1 and counterdie 2, the top of patrix 1 is provided with the deflector 3 being communicated with patrix 1, the top of deflector 3 is provided with controls the temperature-constant plate 4 that sizing material keeps constant temperature, the above and below of temperature-constant plate 4 is respectively equipped with the glue muzzle 5 He Liuliao roads 6 that are interconnected, and glue muzzle forms sizing material reservoir cavity between 5 Yu Liuliao roads 6.
In temperature-constant plate 4, be also provided with passage of heat 7, a side of temperature-constant plate 4 is provided with the thermal hole 8 of connecting with passage of heat 7, and passage of heat 7 is connected and carries out thermostatted water circulation with extraneous water die heater.
Between deflector 3 and patrix 1, be provided with thermal insulation board 9, on deflector 3 and thermal insulation board 9, be equipped with the material guide hole 10 that keeps patrix 1 and temperature-constant plate 4 Liu Liao roads 6 to connect.
Product 11 is arranged between patrix 1 and counterdie 2, the temperature-constant plate of this constant temperature runner rubber injection mode structure is by the circulation of warm water, the rubber injecting is remained within the scope of stationary temperature, can because of not using for a long time, hardening cause the waste of rubber, overcome high and not high with the mould matching degree defect of traditional cold runner equipment cost; This rubber injection mode structure can be according to the size of mould structure, and appropriate design heater plays energy-conservation effect, low cost of manufacture, and the thermal insulation board being provided with between deflector and patrix, avoids sizing material incipient scorch.
Realized continuous production, reduced the generation of runner waste material, made typical products in mass production can realize massive plate press and produce, do not worried causing the cost of material of product to increase due to the generation of runner waste material.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and description, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications; these changes and improvements all fall in claimed scope of the present utility model, and the protection domain that the utility model requires is defined by appending claims and equivalent thereof.
