Abstract
The utility model discloses a radiator gland-strip compression-molding-forming die that is used for the cooling system of the engine, which comprises an upper die and a lower die, wherein, an upper die core is arranged inside the upper die; a lower die core is arranged inside the lower die; a die cavity is arranged between the upper die and the lower die; the periphery of the die cavity is provided with a tearing groove. The die is used to produce a gland strip of an engine cooling system through a vacuum sulfuration craftwork; the surface of the gland strip product is free from pastiness; the flash is removed at one time; the output per shift is large; the size and the performance of the product are stable, thus completely meeting standard requirements of the high-performance EPDM gland strip and meeting the development requirements of the automobile industry.
Description
Technical field
The utility model relates to a kind of mould, specifically is a kind of engine-cooling system radiator sealing strip mould.
Background technology
Along with developing rapidly of auto industry, the sealing strip that uses in the car engine cooling system has been proposed to bear temperature requirement up to more than 150 ℃, EPDM rubber adopts peroxide vulcanizing system can satisfy this requirement preferably.But the sizing material that adopts peroxide vulcanizing system sulfidation easily and oxygen react, cause the sealing strip surfaces of tacky, and cure time is longer; Because product self is big and long, cavity quantity was less when mould generally designed simultaneously.Sulfurizing mould adopts the injection moulding vulcanization mould abroad, and the die cavity number is few, and class's output is little, and equipment has high input, single products manufacturing cost height.
The utility model content
The purpose of this utility model provides a kind of engine-cooling system radiator sealing strip compression molding mould, mould is designed to compression molding torn edges mould, equipment adopts the compression molding make-up machine that vacuumizes, and sulfuration process adopts the quick one section deoxygenation sulfuration of high temperature to add the method for post vulcanization typing.Vulcanize that the product surface that is not clamminess, the die cavity number is many, production efficiency is high, cost is low, steady quality.
The technical solution of the utility model is as follows:
A kind of engine-cooling system radiator sealing strip compression molding mould, it is characterized in that including upper die and lower die, upper mold core is installed in the patrix, lower mold core is installed in the counterdie, between the upper and lower mould die cavity is arranged, around the described upper and lower model cavity torn edges groove is arranged, the counterdie core rod has the torn edges groove in each hole.
Described torn edges groove structure adopts hexgonal structure, and the torn edges groove is high the facing directly of 0.2-0.4mm near die cavity one side.
In described torn edges slot pitch die cavity distance is 0.1-0.15mm.
The present invention is that a kind of sealing strip of peroxide vulcanizing system that is applicable to utilizes the torn edges mould on the evacuated flat panel vulcanizer, and takes the quick one step cure moulding of high temperature to add the product manufacture of constant temperature post vulcanization typing mode.
The release chamber of the utility model torn edges mould torn edges slot pitch is generally 0.1-0.15mm (product allows overlap to be generally 0.3-0.4mm), and mould structure adopts the compression molding structure, and the product overlap takes torn edges to handle.Torn edges groove structure adopts hexgonal structure, and is processing facing directly of 0.2-0.4mm by die cavity one side, guarantees that the disposable removing of torn edges is clean, can not leave overlap.
The utility model mould need be to produce on 550mm * 600mm and the above vacuum vulcanization press at hot plate, and temperature keeps stable when guaranteeing to vulcanize, and sulfuration process is taked the quick one step cure moulding of high temperature, 190 ℃, 2.5 minutes; Add the typing of constant temperature post vulcanization, 170 ℃, 1 hour.
During production, mould is installed on the vacuum vulcanization press, by pressure, curing temperature, the cure time of setting the vacuum vulcanization press with vacuumize the deoxygenation time, temperature reaches the back profiled member is contained in the mold cavity, by the beginning key, vulcanizing press carries out matched moulds, feeding automatically, pressurization, vacuumize, the depanning automatically of sulfuration back is finished in sulfuration in the stipulated time, take out product, one step cure is finished.Carry out deburring after the product depanning, overlap can disposablely tear totally. and carry out the post vulcanization of product then, guarantee that properties of product are stable, size, outward appearance meet standard-required.

Fig. 3 is that the utility model B-B is to cutaway view.
The specific embodiment:
A kind of engine-cooling system radiator sealing strip compression molding mould, include patrix 1, counterdie 2, upper mold core 3 is installed in the patrix 1, lower mold core 4 is installed in the counterdie 2, between the upper and lower mould 1,2 die cavity 5 is arranged, torn edges groove 6 is arranged, porose torn edges groove 7 in the lower mold core 4 around the described upper and lower model cavity.Torn edges groove 6 structures adopt hexgonal structure, and torn edges groove 6 is high the facing directly of 0.2-0.4mm near die cavity 5 one sides, and torn edges groove 6 is 0.1-0.15mm apart from die cavity 5 distances.
Claims (3)
1. an engine-cooling system is with radiator sealing strip compression molding mould, it is characterized in that including upper die and lower die, upper mold core is installed in the patrix, lower mold core is installed in the counterdie, between the upper and lower mould die cavity is arranged, around the described upper and lower model cavity torn edges groove is arranged, the counterdie core rod has the torn edges groove in each hole.
2. engine-cooling system according to claim 1 is characterized in that with radiator sealing strip compression molding mould described torn edges groove structure adopts hexgonal structure, and the torn edges groove is high the facing directly of 0.2-0.4mm near die cavity one side.
