Abstract
The utility model discloses an external bracing demoulding mechanism of an automobile bumper injection mould, which comprises an upper compound plate and a lower compound plate. The upper compound plate is connected with a die cavity plate through a cushion block; a die core fixing plate is installed on the lower compound plate; a centre plate is arranged in the die core fixing plate; a centre is connected on the centre plate; a die core embedded lump is installed on the die core fixing plate; a formed automobile bumper is formed between the die core embedded lump and the die cavity plate; barbs are respectively arranged at two ends of the bumper; the demoulding mechanism is characterized in that sliding chutes are respectively arranged on two sides of the die core fixing plate; an external bracing sliding block is arranged in each sliding chute; the tops of the external bracing sliding blocks are matched with the barbs; external bracing cylinders are installed on two side walls of the die core fixing plate; and a piston rod of each external bracing cylinder is connected with each external bracing sliding block. The demoulding mechanism adopts a mode that the external bracing cylinders drive the external bracing sliding blocks to be externally pulled, so that the barbs of the bumper are externally pulled and deformed, and the barbs lose contact with the die core embedded lump; therefore, the structure is simple, and the operation is stable and reliable.
Description
Technical field
The utility model relates to a kind of bumper injection mould and pulls mold mechanism outward, belongs to the mould of plastics field.
Background technology
Adopt injection mold to produce plastic product, as bumper etc., bumper can play protective action, can play decoration function again.Firm for bumper is installed, be shaped on barb at bumper at two ends, when ejecting, product needs earlier barb to be deviate from, adopt traditional mold releasability difficulty
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 that bumper two ends barb is pulled outwardly dynamic deformation, barb and mold cores side are inserted disengage, and the bumper injection mould that helps the demoulding pulls mold mechanism outward.
The technical scheme that the utility model bumper injection mould pulls mold mechanism outward is: comprise compound plate and following compound plate; last compound plate connects cavity plate through cushion block; on the following compound plate core fixing plate is installed; ejector retainner plate is set in the core fixing plate; connect thimble on the ejector retainner plate; core is installed on the core fixing plate to be inserted; core insert and cavity plate between the bumper of moulding is arranged; the two ends of bumper are shaped on barb respectively; it is characterized in that described core fixing plate both sides make chute respectively; the outer slide block that draws is set in the chute; draw the top of slide block to match outward with barb; draw oil cylinder outside on the end walls of core fixing plate, installing, draw the piston rod of oil cylinder to connect the outer slide block that draws outward.
Bumper injection mould of the present utility model pulls mold mechanism outward; during the demoulding; at first insert and the cavity plate die sinking by folding mould power drive core fixing plate and core; make the outer surface demoulding of bumper; at this moment; the two ends barb of bumper wraps on core inserts; can not directly be ejected outside the mould; therefore, draw oil cylinder work outward, drive the outer slide block that draws that matches with barb and outwards slide; it is sliding outward to draw the slide block band barb outward; the distortion of bumper barb position is inserted with core disengage, by thimble and jacking block bumper is ejected outside the mould at last, the demoulding is finished.This programme adopts outer drawing outside the oil cylinder drive to draw slide block to draw mode outward, makes outside the bumper barb position and draws distortion, and barb and core are inserted and disengaged, and be simple in structure, moves reliable and stable.
Bumper injection mould of the present utility model pulls mold mechanism outward, is equipped with wearing plate in the described chute, and wearing plate contacts with drawing slide block outward, and wearing plate has been arranged, and chute does not does not wear and tear.
Description of drawings
Fig. 1 is that the utility model bumper injection mould pulls the mold mechanism structural representation outward.
The specific embodiment
The utility model relates to a kind of bumper injection mould and pulls mold mechanism outward; as shown in Figure 1; comprise compound plate 1 and following compound plate 2; last compound plate 1 connects cavity plate 5 through cushion block 3; core fixing plate 11 is installed on the following compound plate 2; ejector retainner plate 6 is set in the core fixing plate 11; connect thimble 7 on the ejector retainner plate 6; core is installed on the core fixing plate 11 is inserted 8; core insert 8 and cavity plate 5 between the bumper 9 of moulding is arranged; the two ends of bumper 9 are shaped on barb 10 respectively; it is characterized in that described core fixing plate 11 both sides make chute 13 respectively, be provided with in the chute 13 and draw slide block 12 outward, draw the top of slide block 12 to match outward with barb 10; draw oil cylinder 14 outside on the end walls of core fixing plate 11, installing, draw the piston rod 15 of oil cylinder 14 to connect the outer slide block 12 that draws outward.During the demoulding, at first by folding mould power drive core fixing plate 11 and core insert 8 with cavity plate 5 die sinkings, make the outer surface demoulding of bumper 9, at this moment, the two ends barb 10 of bumper 9 wraps in core and inserts on 8, can not directly be ejected outside the mould, therefore, draw oil cylinder 14 work outward, drive the outer slide block 12 that draws match with barb 10 and outwards slides, draw slide block 12 being with barb 10 outer sliding outward, bumper 9 barbs 10 positions are out of shape and core is inserted and 8 disengaged, by thimble and jacking block bumper is ejected outside the mould at last, the demoulding is finished.This programme adopts outer drawing outside the oil cylinder drive to draw slide block to draw mode outward, makes outside the bumper barb position and draws distortion, and barb and core are inserted and disengaged, and be simple in structure, moves reliable and stable.Be equipped with wearing plate 16 in the described chute 13, wearing plate 16 contacts with drawing slide block 12 outward, and wearing plate has been arranged, and chute does not does not wear and tear.
