Abstract
The utility model discloses a mold suitable for preparing radiation crosslinked polypropylene, which comprises a female mold, a male mold and a cover plate. The female mold which is internally provided with a concave mold chamber is positioned below the male mold and is provided with an electric heating plate at the bottom. The cover plate which is fixedly connected through bots is provided at the upper part. The male mold is fixed on the cover plate and is sleeved by a spring. Furthermore the spring is provided at the inside of the cover plate and is fixed to the bottom of the cover plate. The central part of the male mold is provided with a through exhaust hole. The lower end of the exhaust hole is same with a forming space which is formed by the female mold and the male mold. The upper end of the exhaust hole is communicated with the outside of the male mold. According to the utility model, through setting the electric heating plate at the bottom of the female mold, the foaming forming is facilitated. Simultaneously the spring is equipped on the male mold, and the mold pressing between the male mold and the female mold is buffered. A foaming space is formed and the controlling for the foaming forming is facilitated. The male mold is provided with the exhaust hole which is communicated with the foaming space. The foam generated in mold pressing and foaming processes are removed. The performance and qualified rate of the product are improved.
Description
Technical field
The utility model relates to a kind of foaming molding mold, and being specifically related to is the foamed moulded mould that a kind of radiating crosslinked polypropylene is produced, and can be widely used in the foaming manufacture process of expanded materials such as polypropylene.
Background technology
Foams plastic materials such as polypropylene can be widely used in fields such as automobile, refrigeration, building, oil.The die apparatus that existing foaming manufacture process is adopted mostly is provided with injection apparatus, and the meeting leftover waste material must be cleaned previous leftover waste material during secondary injection after spraying first, and this process wastes raw material, and the matting that induced one, and has increased cost.The foaming mould device that Chinese patent CN1846963A is announced, the spray nozzle device that mould is provided with, this device wastes raw material, clean loaded down with trivial details, and its mould structure complexity, coefficient of foaming is wayward, the operating process complexity, particularly in the control of foaming space, more restive, and the product bubble ratio is more, and product percent of pass is low.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, a kind of novel plastic foamed compression molding mould is provided, this mould more helps foaming by in the former bottom electric boiling plate being set, and spring is set on formpiston simultaneously, mold pressing between buffering formpiston and the former, form the foaming space, more help controlling foaming, on formpiston, have the steam vent that communicates with the space of foaming, elimination produces bubble in mold pressing and foaming process, enhance product performance and qualification rate.
The purpose of this utility model realizes by the following technical solutions:
A kind of mould that is applicable to that radiating crosslinked polypropylene is produced, comprise former, formpiston, cover plate, it is characterized in that: below and bottom that the former that inside has a matrix model cavity is positioned at formpiston are provided with electric boiling plate, there is the cover plate that is bolted to connection the top, formpiston is fixing on the cover board, be with spring on the formpiston, and spring is positioned at the inboard of cover plate and is fixed on the bottom of cover plate, have the steam vent of perforation in the middle of the formpiston, the steam vent lower end is identical with the molding space that former and formpiston form, upper end and formpiston exterior.
It on the steam vent described in the utility model side direction exterior with formpiston.
Spring described in the utility model is fixed on the boss of cover plate lower inside, and formpiston passes spring.
Hydraulic press pressure described in the utility model is: 3 MPas---10 MPas.
2 millimeters-4 millimeters of spring steel wire diameter of phi described in the utility model.
Steam vent numerical digit described in the utility model is 2.
Operation principle of the present utility model: earlier foaming raw material is placed on the former bottom, 4 clamping screws that then cover plate covered are locked with former.By the roof jack at top with the formpiston bottom with compressed by foamed products, its pressure is greater than the elastic force energising heating mould of spring, with product by heating to blowing temperature, pressurize, hydraulic press slowly reduces pressure, simultaneously under the effect of elastic force, formpiston rises gradually, and product begins foaming, and by the pore exhaust.Final top pressure is kept to zero, and elastic force returns to original state with formpiston, and foaming is finished.
The utility model compared with prior art has following technique effect:
The utility model is by being provided with electric boiling plate in the former bottom, more help foaming, spring is set on formpiston simultaneously, mold pressing between buffering formpiston and the former, form the foaming space, more help controlling foaming, on formpiston, have the steam vent that communicates with the space of foaming, elimination produces bubble in mold pressing and foaming process, enhance product performance and qualification rate.
Plastic foamed press mold mould device structure described in the utility model is simple, operating process is simple, in this mould, need not clean injection apparatus, runner need be set, so it is residual not have waste material, and coefficient of foaming can be applicable to the usefulness of expanded plastic material formulating experiment by the Stroke Control of spring very much.

The specific embodiment
A kind of mould that is applicable to that radiating crosslinked polypropylene is produced, comprise former 5, formpiston 1, cover plate 2, it is characterized in that: below and bottom that the former 5 that inside has a matrix model cavity is positioned at formpiston 1 are provided with electric boiling plate 8, the top has by the fixedly connected cover plate 2 of bolt 4, formpiston 1 is fixed on the cover plate 2, be with spring 3 on the formpiston 1, and spring 3 is positioned at the inboard of cover plate 2 and is fixed on the bottom of cover plate 2, have the steam vent 6 of perforation in the middle of the formpiston 1, steam vent 6 lower ends are identical with the molding space that former 5 and formpiston 1 form, upper end and formpiston 1 exterior.
Steam vent described in the utility model 6 upper ends are the side direction exterior with formpiston 1.
The utility model mainly is applicable to the preparation radiating crosslinked polypropylene, better foaming.
