Description

Plastic chair mold releasability mechanism
Technical field
The utility model relates to a kind of mould emptier of plastic chair mould, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, the plastic chair of using in the daily life for example, plastic chair mainly comprises chair pin, seat support and the chair back three parts composition, therefore, the height of a chair is generally all than higher, if adopt traditional mould to produce, the plastic chair forward is arranged in the mould, during the demoulding, the ejection height height of plastic chair, demoulding difficulty.Particularly require the opening stroke of injection machine long, therefore, need large-scale injection machine just can produce, cost investment is big.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of employing horizontal ejection device, reduce mold height, shorten opening stroke, save cost, being applicable to the plastic chair mold releasability mechanism that middle-size and small-size injection machine is produced.
The technical scheme of the utility model plastic chair mold releasability mechanism is: comprise mold cavity plate and core plate; the chair back cavity block is installed in the cavity plate; the chair back core is installed in the core plate to be inserted; between inserting, chair back cavity block and chair back core constitute the chair back die cavity; it is characterized in that horizontally set chair pin seat support cavity block between described cavity plate and the core plate; constitute chair pin seat support die cavity between chair pin seat support cavity block and cavity plate and the core plate; chair pin seat support die cavity and chair back die cavity are formed the plastic chair die cavity; the moulding plastics chair is arranged in the plastic chair die cavity; at chair pin seat support cavity block both sides outer wall demoulding oil jar is installed; the piston rod of demoulding oil jar connects cavity plate; the end of chair pin seat support cavity block is provided with top board; connect push rod on the top board; push rod passes chair pin seat support cavity block and contacts with the plastic chair seat support; the bottom of top board connects the piston rod that ejects that ejects oil cylinder, and the push rod that ejects on the oil cylinder drive top board ejects action.
Plastic chair mold releasability of the present utility model mechanism; during work; at first drive core plate and cavity plate and the die sinking of chair pin seat support cavity block by injection machine power; core plate moves downward; make the backrest core part demoulding of plastic chair; then demoulding oil jar action; the piston rod of demoulding oil jar promotes cavity plate, because cavity plate is to be fixed on the template of injection machine, therefore; chair pin seat support cavity block is subjected to reaction force and moves downward; make the backrest die cavity part demoulding of plastic chair, at this moment, the complete demoulding of the back part of plastic chair; and chair pin and seat bottom part are still on chair pin seat support cavity block; at this moment, eject cylinder action, the push rod on the drive top board withstands on the bottom of plastic chair seat support; plastic chair chair pin is ejected chair pin seat support cavity block, and the plastics demoulding is finished.The plastic chair of this programme adopts horizontal ejection device, reduces mold height, and opening stroke is short, is specially adapted to middle-size and small-size injection machine production, saves cost investment greatly.
Plastic chair mold releasability of the present utility model mechanism, described chair pin seat support cavity block end is equipped with base plate, and eject oil cylinder and be installed on the base plate, plate with the end, it is easy for installation, firm to eject oil cylinder.Flexibly connected by guide pillar between described cavity plate, chair pin seat support cavity block and the core plate, guide pillar is easy to connect, reliable, and chair pin seat support cavity block and core plate move up and down smooth and easy.
