Abstract

The utility model provides an O-shaped ring double-layer die structure, which comprises upper dies and lower dies, wherein a plurality of O-shaped ring die cavities are formed between the upper dies and the lower dies, the upper dies and the lower dies comprise two respectively and respectively form a first group of dies and a second group of dies, wherein the lower die of the first group of dies is fixedly installed on the upper surface of the upper die of the second group of dies, supporting blocks are installed on the lower surface of the upper die or/and the upper surface of the lower die which is matched with the upper die, and a gap which is provided for glue materials to flow freely and is communicated with the O-shaped ring die cavities is formed after the upper die and the lower die are buckled. Electric heating pipes are respectively installed in the lower die of the first group of dies and the upper die of the second group of dies. Two rows of idler wheels are respectively installed on two sides of the lower die of the second group of dies. The O-shaped ring double-layer die structure is used to connect un-pressed flashing edges into pieces, and press and vulcanize the flashing edges, thereby avoiding the generation of holding glue, dies can be taken in pieces, and the production efficiency can be greatly improved.

Description

O type circle double stack mold structure
Technical field:
The utility model relates to the rubber processing mould, a kind of specifically O type circle double stack mold structure.
Background technology:
Along with the economic develop rapidly of China, the output of automobile rubber spare and accessory parts is also in growth at full speed, and automobile rubber parts secondary industry steps into the stage of ripeness, but wherein the mode of production of some product has much room for improvement.O type circle is a BOSCH brake system of car whole world project, is used for the sealing of vacuum booster, and is strict, do not allow any defective, has multiple dimensions.Traditional O type circle production method has 3 kinds at present:
First kind is mould single movingly chamber moulding, and this mode is suitable for bigger O type circle, and defective is a single chamber delivery, and mould is taken off glue and deflashing difficulty, inefficiency easily.
Second kind is dull and stereotyped O type circle, and die cavity directly mills out on template, and this kind is suitable for the very little O type circle of diameter, and shortcoming is that size is restricted.
The third is the structure of dull and stereotyped band core rod, and this structure die cavity also is to mill out on template, and profiled member is located with core rod, is suitable for the O type circle of intermediate diameters, and it is serious that shortcoming is that product is taken off glue.
Above traditional structure all exists takes off the serious problem of glue, and mainly being EPDM rubber under the situation of pressurized not, sulfuration produces, and causes qualification rate low and production efficiency is low, and then has influence on economic benefit of enterprises.
The utility model content:
The utility model provides a kind of O type circle double stack mold structure, and the overlap of pressurized not is linked to be sheet and pressurized sulfuration, has solved the glue problem of taking off.
Technical solutions of the utility model:
O type circle double stack mold structure, include upper die and lower die, be formed with a plurality of O type circle die cavitys between the upper die and lower die, described upper die and lower die respectively have two, constitute first, second group mould respectively, wherein the counterdie of first group of mould is fixedly mounted on the upper surface of the patrix of second group of mould, and described patrix lower surface is or/and the counterdie upper surface that is mated is equipped with back-up block, form in patrix and the involutory back of counterdie for sizing material flow freely and with the gap of O type circle die cavity UNICOM.
Be separately installed with electric heating tube in the patrix of the counterdie of described first group of mould and second group of mould.The counterdie both sides of described second group of mould are separately installed with row's roller.
The utility model advantage:
The utility model will be not the overlap of pressurized be linked to be sheet and pressurized sulfuration, the generation of having avoided taking off glue so also can the full wafer delivery, significantly enhances productivity.
Description of drawings:
Fig. 1 is a sectional structure schematic diagram of the present utility model.
Fig. 2 is the utility model counterdie structural representation.
The specific embodiment:
O type circle double stack mold structure, include patrix 1, counterdie 2, be formed with a plurality of O type circle die cavitys between patrix 1, the counterdie 2, patrix 1, counterdie 2 respectively have two, constitute first, second group mould respectively, wherein the counterdie 2 of first group of mould is fixedly mounted on patrix 1 upper surface of second group of mould, and described patrix 1 lower surface is or/and counterdie 2 upper surfaces that are mated are equipped with back-up block 3, form in patrix 1 and counterdie 2 involutory backs for sizing materials flow freely and with the gap 4 of O type circle die cavity UNICOM.Be separately installed with electric heating tube in the counterdie 2 of first group of mould and the patrix 1 of second group of mould, counterdie 2 both sides of second group of mould are separately installed with row's roller.

Claims (3)
