Description

The oblique top of Plastic chair die assembly mould emptier

Technical field

The utility model relates to the oblique top of a kind of Plastic chair die assembly mould emptier, belongs to the mould of plastics field.

Background technology

At present, Plastic chair generally all is through the mould of plastics single injection-molded, and it is fast to have a process velocity, and cost is low, characteristics such as can reclaim, and is widely used in restaurant, tourist attraction, meeting room and family etc.The main structure of Plastic chair comprises chair pin, seat support and the chair back; But the seat support of some Plastic chair is provided with handrail; And,, form the groove of a similar back-off with handrail design camber handrail for the profile that makes chair is more attractive in appearance; When the Plastic chair demoulding, be stuck in easily in the mould, cause demoulding difficulty.

Summary of the invention

The purpose of the utility model is in order to overcome the shortcoming of prior art; Provide a kind of through Xie Ding and the combination of straight top; Earlier product jack-up is broken away from die cavity, the handrail back-off is deviate from smoothly, then by the oblique top of the Plastic chair die assembly mould emptier that ejects the whole demoulding of oil cylinder drive Plastic chair.

The technical scheme of the oblique top of the utility model Plastic chair die assembly mould emptier is: comprise upper mould plate and lower bolster, cope match-plate pattern connects solid plate down, and the mould pin is installed on the lower bolster; In the mould pin top board is set, connects push rod on the top board, on the mould pin moving platen is installed; The chair pin is set in the moving platen inserts, moving platen, chair pin insert and solid plate between be shaped on die cavity, the Plastic chair of moulding is arranged in the die cavity; Plastic chair is provided with handrail, and the back side of handrail is fluted, it is characterized in that installing on the described top board oblique slide; Tiltedly connect angle ejector rod on the slide, angle ejector rod matches with the back side groove of handrail, and described push rod stretches into moving platen and inserts with the chair pin and contact; Installation ejects support on the lateral wall that the chair pin is inserted, and ejects to install on the support to eject oil cylinder, ejects oil cylinder and connects liftout plate; Liftout plate connects knock-pin, and knock-pin passes the chair pin and inserts and contact with the seat support back side of Plastic chair.

The oblique top of the Plastic chair die assembly mould emptier of the utility model during the demoulding, at first is to drive moving platen and solid plate die sinking by injection machine power, after the die sinking; Top board action drives angle ejector rod and the push rod jack-up that makes progress, on the one hand; Matching with the back side groove of handrail in the top of angle ejector rod, angle ejector rod is upwards being skidded off, on the other hand in the jack-up from groove; Push rod drives the upwards operation of inserting of chair pin, and Plastic chair is stayed on the chair pin inserts, and the chair back of Plastic chair is deviate from from moving platen; At last, eject oil cylinder work and drive liftout plate, liftout plate drives knock-pin; Knock-pin contacts with the seat support back side of Plastic chair, and Plastic chair jack-up on the chair pin is inserted is deviate from outside the mould, and the Plastic chair demoulding is accomplished.This programme adopts Xie Ding and straight compound mode of pushing up, and simple in structure, cost is economized, and ejects through secondary, by ejecting oil cylinder Plastic chair is ejected outside the mould at last, and action is stable, reliable.

The oblique top of the Plastic chair die assembly mould emptier of the utility model; Described chair pin is provided with guide pillar in inserting; Upper and lower two of guide pillar connects solid plate and moving platen respectively, and guide pillar is inserted the chair pin and under push rod drives, operated steadily the inserted guide effect of mould pin.
