Abstract
A plastic bumper internal-drawing demoulding mechanism comprises an upper mold plate and a lower mold plate, wherein the upper mold plate is connected with a cavity, the lower mold plate is provided with an ejector plate and a support block, a straight ejector rod and a lifter rod are mounted on the ejector plate, and an insert is mounted on the support block. The plastic bumper internal-drawing demoulding mechanism is characterized in that an arc-shaped chute is fabricated in the cavity, an inner slider is mounted on one side of the arc-shaped chute and connected with the lifter rod, the inner slider is pierced by a core inside, a compression spring is arranged between the core and the inner slider, and one end of the core contacts with a bumper mounting hole while the other end thereof contacts with the arc-shaped chute. The plastic bumper internal-drawing demoulding mechanism is simple and compact in structure, and adopts an internal drawing structure that the core is mounted in the inner slider which is driven by the lifter rod and then the inner slider drives the core to slide upwards along the arc-shaped chute and to release from the bumper mounting hole. Besides, the lifter rod is driven by power of an injection mold, and then the plastic bumper internal-drawing demoulding mechanism dose not need extra internal-drawing power, thereby reducing production cost.
Description
Technical field
The utility model relate to a kind of plastics bumper in take out mould emptier, particularly relate to bumper (bumper) pilot hole in take out the demoulding.
Background technology
Along with the day by day raising of people to all kinds of lives, industrial goods appearance requirement, as the plastic products of all kinds of articles for use profile coverings, its outward appearance condition becomes the key factor that people estimate product appearance naturally.Wherein whether the goods parting line is exposed on the important appearance (outer surface), and having become influences people and accept one of key element of product.Automotive plastic bumper for example; smooth, attractive in appearance for guarantee insurance thick stick profile; in the existing mold structure; the die joint (line) of bumper is designed in product appearance visible surface die cavity inboard, be about to move on the die joint, be positioned at the maximal projection outline line place bottom surface of bumper (product) in the withdrawing pattern direction; but; after moving on the die joint, the outer mould emptier of taking out that is positioned at the bumper pilot hole under this position does not just have the installation site, causes demoulding difficulty.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide in a kind of employings and take out mode, by the drive of injection machine power, need not to put in addition outer twitch force, and is simple in structure, easy for installation, takes out mould emptier in the low plastics bumper of cost.
The technical scheme of taking out mould emptier in the utility model plastics bumper is: take out mould emptier in the plastics bumper; comprise cope match-plate pattern and lower bolster; cope match-plate pattern connects die cavity; top board and mould pin are installed on the lower bolster; straight push rod and angle ejector rod are installed on the top board; on the mould pin core is installed; it is characterized in that being shaped on arc chute in the described core; one side of arc chute is installed inner slide; angle ejector rod connects inner slide, has fuse to pass in inner slide, and the compression spring is arranged between fuse and the inner slide; one of fuse contacts with the bumper installing hole, and the other end of fuse contacts with arc chute.
Take out mould emptier in the plastics bumper of the present utility model; during the demoulding; at first drive core and die cavity die sinking by injection machine; top board drives straight push rod and angle ejector rod up pushes up; straight top board drives and ejects the jack-up product of inserting; angle ejector rod also drives upwards top of inner slide simultaneously; inner slide drives fuse; fuse upwards slides along the arc chute of core; and under the elastic force effect of compression spring; fuse is deviate from from the bumper installing hole, and promptly fuse is done inwardly motion with respect to inner slide, and fuse breaks away from from installing hole.But after fuse slided into the maximum radian M point position of arc chute, arc chute sloped inwardly after deviating from, and fuse outwards ejects action with respect to inner slide, sticks on the inner slide as fruit product, product and inner slide can be broken away from fully.。This programme is simple in structure, compact, take out structure in the employing, fuse is installed in inner slide, utilize angle ejector rod to drive inner slide, inner slide drives fuse and upwards slides along arc chute, and fuse is deviate from from the bumper installing hole, and angle ejector rod is driven by injection machine power, need not to put interior twitch force in addition, reduce production costs.
Take out mould emptier in the plastics bumper of the present utility model, in the described inner slide compact heap is installed, fuse passes compact heap, and compact heap contacts with the compression spring, and compact heap is pushed down the compression spring, makes the compression spring force big, and fuse is deviate from easily.Described angle ejector rod is connected by screw with inner slide, and is easy to connect, firm.
Description of drawings
Fig. 1 takes out the mould emptier structural representation in the utility model plastics bumper;
Fig. 2 is the A place partial enlarged drawing of Fig. 1.
The specific embodiment
The utility model discloses in a kind of plastics bumper and take out mould emptier; as Fig. 1; shown in Figure 2; comprise cope match-plate pattern 1 and lower bolster 2; cope match-plate pattern connects die cavity 3; top board 4 and mould pin 5 are installed on the lower bolster; straight push rod 6 and angle ejector rod 7 are installed on the top board; core 8 is installed on the mould pin; it is characterized in that being shaped on arc chute 13 in the described core 8, a side of arc chute 13 is installed inner slide 9, and angle ejector rod 7 connects inner slide; in inner slide 9, there is fuse 10 to pass; compression spring 12 is arranged between fuse and the inner slide, and of fuse contacts with bumper 11 installing holes 12, and the other end of fuse contacts with arc chute 13.During the demoulding, at first drive core 8 and die cavity 3 die sinkings by injection machine, top board 4 drives straight push rod 6 and angle ejector rod 7 up pushes up, and straight top board 6 drives and ejects the jack-up product of inserting, and angle ejector rod 7 also drives upwards top of inner slide 9 simultaneously, inner slide 9 drives fuse 10, fuse 10 upwards slides along the arc chute 13 of core 8, and under the elastic force effect of compression spring 12, fuse 10 is deviate from from bumper 11 installing holes 16, be that fuse 10 is done inwardly motion with respect to inner slide 9, fuse breaks away from from installing hole.But after fuse 10 slided into the maximum radian M point position of arc chute 13, arc chute sloped inwardly after deviating from, and fuse 10 outwards ejects action with respect to inner slide 9, sticks on the inner slide 9 as fruit product, product and inner slide can be broken away from fully.This programme is simple in structure, compact, take out structure in the employing, fuse is installed in inner slide, utilize angle ejector rod to drive inner slide, inner slide drives fuse and upwards slides along arc chute, and fuse is deviate from from the bumper installing hole, and angle ejector rod is driven by injection machine power, need not to put interior twitch force in addition, reduce production costs.Compact heap 14 is installed in the described inner slide 9, and fuse 10 passes compact heap, and compact heap 14 contacts with compression spring 12, and compact heap is pushed down the compression spring, makes the compression spring force big, and fuse is deviate from easily.Described angle ejector rod 7 is connected by screw 15 with inner slide 9, and is easy to connect, firm.
