Abstract

The invention relates to the field of mold equipment, in particular to an ejection cold-runner mould of an automobile rubber vent pipe. The ejection cold-runner mould comprises an upper mould plate and a lower mould plate. Inward-concave structures are arranged at corresponding positions of the upper mould plate and the lower mould plate, and mould cores are arranged in the inward-concave structures obtained after the upper mould plate and the lower mould plate are combined. A fixed locating plate is arranged on the upper surface of the upper mould plate. A heat insulation plate is arranged on the upper surface of the fixed locating plate. A constant-temperature plate is arranged on the upper surface of the heat insulation plate. A runner plate is arranged on the upper surface of the constant-temperature plate. A main runner is arranged on the runner plate. Branch sprues are arranged between the main runner and the inward-concave structures of the upper mould plate. Electric heating pipes are arranged in the upper mould plate. According to the ejection cold-runner mould of the automobile rubber vent pipe, by means of the constant-temperature plate, rubber in the branch sprues keeps at needed temperature all the time, and therefore dead rubber is reduced, the raw material waste is reduced, cleaning on the interiors of the branch sprues is reduced, and the processing efficiency is improved.

Description

Automobile rubber breather pipe injection cold runner die
Technical field
The present invention relates to field of die equipment, especially a kind of automobile rubber breather pipe injection cold runner die.
Background technology
Existing injection rubber mold, after the production of each mould completes, needs to clear up its runner, and needs to spend within several minutes, clear up according to the structure of product, can produce more scrap rubber material in the process, cause the serious waste of raw materials for production.Simultaneously existing mould improper do lighter weight product and the shorter product of cure time, reason the sizing material in runner can be removed in each scale removal process, be empty in runner.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and provide a kind of structure simple, the automobile rubber breather pipe injection cold runner die that dead glue in runner produces can be reduced.
In order to achieve the above object, a kind of automobile rubber breather pipe injection cold runner die designed by the present invention, it comprises cope match-plate pattern and lower bolster, cope match-plate pattern and lower bolster corresponding position are provided with concave inward structure, be provided with the mould heart in concave inward structure after cope match-plate pattern and lower bolster combination, the space between the mould heart and concave inward structure forms rubber breather pipe molding space; The upper surface of cope match-plate pattern is provided with stationary positioned plate, the upper surface of stationary positioned plate is provided with thermal insulation board, the upper surface of thermal insulation board is provided with temperature-constant plate, and the upper surface of temperature-constant plate is provided with runner plate; Runner plate is provided with sprue, is provided with a point cast gate between sprue and the concave inward structure of cope match-plate pattern, a point cast gate is vertically arranged and through cope match-plate pattern, stationary positioned plate, thermal insulation board, temperature-constant plate; The inside of cope match-plate pattern is provided with electrothermal tube, and the length direction of electrothermal tube is consistent with the length direction of concave inward structure.
Technique scheme, above cope match-plate pattern, laminating is provided with stationary positioned plate, thermal insulation board and temperature-constant plate successively, each point of all through whole stationary positioned plate of cast gate, thermal insulation board, temperature-constant plate and cope match-plate pattern simultaneously, in use, temperature-constant plate carries out constant temperature process to point cast gate inside, guarantee that point cast gate inside remains the rubber of uniform temperature and certain pressure, thus rubber stuff outgoing can be carried out with the shortest path after the breather pipe of each mould has been produced, raise the efficiency.Reduce the generation of the dead glue of point cast gate inside simultaneously, reduce the waste of raw material.Simultaneously because the sizing material injection time is shorter, it is made to be applicable to the product of the shorter and lighter weight of processing cure time.
As optimization, the structure of described temperature-constant plate is: temperature-constant plate inside is provided with roundabout circulation duct, and the two ends of circulation duct are separately positioned on the sidewall of temperature-constant plate, and wherein one end is as water inlet, the other end is as delivery port, and delivery port, water inlet are all connected with constant temperature cooler.The setting of this structure can make temperature-constant plate inside be connected with constant temperature cooler, thus makes the temperature of temperature-constant plate keep stable, carries out constant temperature process, thus guarantee a point temperature remained constant for the sizing material of cast gate inside to a point cast gate.And when producing the product of only sizing material, can set the temperature of temperature-constant plate, to reach the user demand of different sizing material.
As optimization, described circulation duct is crisscross pipeline composition, and the local location of pipeline is provided with plug, and convoluted conduit is circulated.The setting of this structure, the processing of convenient internal pipeline, and according to the actual requirements, the circulation path of circulation duct can be selected, thus guarantee that the constant temperature stability of temperature-constant plate is high.
Concave inward structure quantity on described cope match-plate pattern is four, and on each concave inward structure, interval is provided with four points of cast gates uniformly, and be all connected with sprue above all point cast gates, sprue forms main charging aperture after centre position is converged.
The automobile rubber breather pipe injection cold runner die that the present invention obtains, described point cast gate adopts straight hole charging, thermal insulation board adopts refractory glass fibre plate, utilize the setting of temperature-constant plate simultaneously, the temperature of the needs that the sizing material of score cast gate inside is remained, thus reduce the generation of dead glue, reduce wastage of material, reduce the cleaning to point cast gate inside, improve working (machining) efficiency.
