Abstract
The invention discloses a mechanism for removing a plastic backrest mold, which comprises an mold upper doubling plate and a mold lower doubling plate, wherein the upper doubling plate is connected with a cushion block; the cushion block is connected with a cavity-shaping insert; a mold support is installed on the lower doubling plate; a core-shaping insert is installed on the mold support; a mold cavity is formed between the core-shaping insert and the cavity-shaping insert; a molded plastic backrest is placed in the mold cavity; and a fixing hole is formed at the bottom of the plastic backrest. The mechanism is characterized in that: the plastic backrest is arranged in the mold cavity in an inclined way; an inclined support is installed on the bottom face of the core-shaping insert; a cylinder with an inclined top is arranged on the inclined support and connected with an inclined ejector plate; the inclined ejector plate is connected with an inclined ejector rod; the inclined ejector rod passes through the core-shaping insert to contact with the fixing hole; and the central line of the inclined ejector rod is consistent with that of the fixing holes. In this scheme, the backrest is placed in the mold in an inclined way, an ejector mechanism is arranged in an inclined way at the same time and the ejector rod of the ejector mechanism corresponds to the fixing hole of the backrest; and thus, the fixing hole is easy to demould, the mold is short, mold materials are saved, and cost is low.
Description
Technical field
The present invention relates to a kind of mechanism for removing plastic backrest mold, belong to the mould of plastics field.
Background technology
Adopt mould of plastics to produce plastic product, the plastic chair of for example using in the daily life, the main structure of plastic chair comprises that chair pin, seat support and the chair back three parts form, therefore, when producing, chair pin, seat support and the chair back can be one-body molded, also can divide body formedly, are connected and fixed by connector again.In order to make connection firm, be shaped with fixing hole on the chair back, therefore more, traditional moulds is when producing the chair back, all chair back forward is arranged in the mould, its benefit is that the fixing hole straight top demoulding is easy, still, because much higher the height of the chair back is, used mould material is also more, particularly when chair back integral body is deviate from, requires the opening stroke of injection machine long, therefore need large-scale injection machine just can produce, cause cost investment to increase.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art; providing a kind of is arranged in the mould the chair back is oblique; while is the other oblique ejecting mechanism that arranges again; the push rod of ejecting mechanism is corresponding with the fixing hole of the chair back; make the fixing hole demoulding easy; mold height is little, and the mould material is economized, the mechanism for removing plastic backrest mold that cost is low.
The technical scheme of mechanism for removing plastic backrest mold of the present invention is: comprise compound plate and lower compound plate on the mould; upper compound plate connects cushion block; cushion block connecting-type cavity insert; the mould pin is installed on the lower compound plate; core is installed on the mould pin to be inserted; core insert and cavity block between form die cavity; the plastics chair back that moulding is arranged in the die cavity; the bottom of the plastics chair back is shaped with fixing hole; it is characterized in that described plastic chair anticline is to being arranged in the die cavity; in the bottom surface that core is inserted inclined support is installed; the oblique top oil cylinder is installed on the inclined support, and the oblique top oil cylinder connects the oblique top plate, and the oblique top plate connects angle ejector rod; angle ejector rod passes core and inserts and contact with fixing hole, and the center line of angle ejector rod is consistent with the center line of fixing hole.
Mechanism for removing plastic backrest mold of the present invention; described plastic chair anticline is to being arranged in the die cavity; namely with the die cavity of the plastics chair back and core oblique opening in cavity block and core are inserted respectively; so the plastics chair back of moulding is also with regard to the oblique mould that is arranged in; its advantage is to save the mould material; reduce mold height; shorten mould open/close line journey; be fit to middle-size and small-size injection machine production; but because the plastic chair anticline is to being arranged in mould; so that the fixing hole of plastic chair back end section is also tilting; the straight top (pin) that is driven by injection machine power can not cooperate with fixing hole, can't the demoulding, therefore; the oblique ejecting mechanism that is driven by the oblique top oil cylinder has been installed in the bottom surface that core is inserted; the angle ejector rod that the oblique top oil cylinder drives passes core and inserts and match with fixing hole, and the center line of angle ejector rod is consistent with the center line of fixing hole, directly with plastics chair back ejection die; simple in structure, the demoulding is easy.
Mechanism for removing plastic backrest mold of the present invention, the head of described angle ejector rod is installed slanted kicking block, and slanted kicking block contacts with fixing hole, and slanted kicking block has been arranged, and angle ejector rod cooperates convenient with fixing hole.
Description of drawings
Fig. 1 is mechanism for removing plastic backrest mold structural representation of the present invention;
Fig. 2 is mechanism for removing plastic backrest mold schematic perspective view of the present invention.
The specific embodiment
The present invention relates to a kind of mechanism for removing plastic backrest mold; such as Fig. 1; shown in Figure 2; comprise compound plate 1 and lower compound plate 2 on the mould; upper compound plate 1 connects cushion block 3; cushion block 3 connecting-type cavity inserts 4; mould pin 5 is installed on the lower compound plate 2; core is installed on the mould pin 5 is inserted 6; core insert 6 and cavity block 4 between form die cavity; the plastics chair back 7 of moulding is arranged in the die cavity, and the bottom of the plastics chair back is shaped with fixing hole 8, it is characterized in that the described plastics chair back 7 oblique being arranged in the die cavity; in insert 6 bottom surface of core inclined support 9 is installed; oblique top oil cylinder 10 is installed on the inclined support 9, and oblique top oil cylinder 10 connects oblique top plate 11, and oblique top plate 11 connects angle ejector rod 12; angle ejector rod 12 passes core and inserts and 6 contact with fixing hole 8, and the center line of angle ejector rod 12 is consistent with the center line of fixing hole 8.The described plastics chair back 7 oblique being arranged in the die cavity of this programme, namely with the die cavity of the plastics chair back 4 and core respectively oblique opening built in cavity block 4 and core insert in 6, so the plastics chair back 4 of moulding is also with regard to the oblique mould that is arranged in, its advantage is to save the mould material, reduce mold height, shorten mould open/close line journey, be fit to middle-size and small-size injection machine production, but because the plastic chair anticline is to being arranged in mould, so that the fixing hole 8 of the plastics chair back 7 bottoms is also tilting, the straight top (pin) that is driven by injection machine power can not cooperate with fixing hole, can't the demoulding, therefore, in insert 6 bottom surface of core the oblique ejecting mechanism that is driven by oblique top oil cylinder 10 has been installed, the angle ejector rod 12 that oblique top oil cylinder 10 drives passes core and inserts and 6 match with fixing hole 8, the center line of angle ejector rod 12 is consistent with the center line of fixing hole 8, directly with plastics chair back ejection die, simple in structure, the demoulding is easy.The head of described angle ejector rod 12 is installed slanted kicking block 13, and slanted kicking block 13 contacts with fixing hole 8, and slanted kicking block has been arranged, and angle ejector rod cooperates convenient with fixing hole.
