Abstract

A core pulling mechanism for a positioning ejection block of an injection mold comprises a fixed mold template and a movable mold template, a molded plastic product is arranged between the fixed template and the movable template, and one side of the plastic product is matched with a core puling ejection block. The core pulling mechanism is characterized in that a counter bore is arranged in the core pulling ejection block, and internally provided with a screw, the screw penetrates through the counter bore to be connected with the fixed template, a spring is arranged on the outer wall of the screw, one end of the spring is contacted with the counter bore, the other end of the spring is contacted with the fixed template, a pressing plate is installed in the fixed template, an inclined chute is arranged in the pressing plate, and the outer side wall of the core pulling ejection block is matched with the inclined chute. In the technical scheme, the mode that the ejection block is ejected by the spring is adopted, and the core pulling distance ejected by the spring is small, so that the compactness of the mold can be improved, the strength of the mould can be enhanced, the service life is long, simultaneously the ejection block can be processed easily, the installation is convenient, the expense is low and the cost is saved.

Description

Injection mold location bullet piece core-pulling mechanism
Technical field
The utility model relates to a kind of injection mold location bullet piece core-pulling mechanism, belongs to the plastic moulds technology field.
Background technology
The core-pulling mechanism of at present existing mould generally mostly is the dynamic model slide block structure, and promptly sliding in a side of mould moving platen is provided with slide block, connects Angle Pin under solid plate, and Angle Pin passes slide block, and drives slide block to sliding outside to inside under the effect of mould open/close mould power.The shortcoming that this structure exists is: slide block is loosed core apart from big, and clamp force is big, and corresponding mould volume also increases, and causes the injection machine model also to increase, and causes resources of production waste.
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 spring top to play block mode, compact conformation, simple, easy for installation, processing and manufacturing difficulty is lower, looses core apart from little, does not influence the injection mold location bullet piece core-pulling mechanism of mould volume size.
The technical scheme of the utility model injection mold location bullet piece core-pulling mechanism is: comprise mould solid plate and moving platen, the plastic product that moulding is arranged between solid plate and the moving platen, one side of plastic product matches with the bullet piece of loosing core, it is characterized in that being shaped on counterbore in the described bullet piece of loosing core, screw is arranged in the counterbore, screw passes counterbore and connects solid plate, the screw outer wall is equipped with spring, one of spring contacts with counterbore, the other end of spring contacts with solid plate, pressing plate is installed in solid plate, is shaped on oblique chute in the pressing plate, the lateral wall of the bullet piece of loosing core matches with oblique chute.
Injection mold of the present utility model location bullet piece core-pulling mechanism, during the demoulding, moving platen is driven by injection machine power and moves downward, the bullet piece of the loosing core template of swaying in synchrony under the elastic force effect of spring outwards moves downward along oblique chute, loose core bullet piece and plastic product are disengaged, after sliding into certain distance, the counterbore of loosing core in the bullet piece contacts with screw, the bullet piece of loosing core is held by screw and is no longer moved downward, and moving platen continues to move downward, be with plastic product to deviate from fully from the solid plate and the bullet piece of loosing core, the ejecting mechanism by mould ejects plastic product outside the mould at last, and the demoulding is finished.This programme adopts the spring top to play block mode, and what spring was upspring looses core apart from little, can improve the compactedness of mould, increases the intensity of mould, long service life, and bullet piece handling ease is easy for installation simultaneously, and expense is low, saves cost.
Injection mold of the present utility model location bullet piece core-pulling mechanism is installed wearing plate on the described moving platen, and wearing plate touches with the bottom connection of the bullet piece of loosing core, and anti-template has been arranged, and moving platen does not does not wear and tear, and wearing plate plays upwards to compress the bullet piece of loosing core simultaneously.Be equipped with drag hook on the described moving platen, the bottom of the slide block of loosing core is shaped on the hook groove, and drag hook matches with the hook groove, and during die sinking, drag hook moves downward, drive the bullet piece of loosing core along oblique chute outwards to lower slider, loose core bullet piece and plastic product are disengaged.

Fig. 1 is the utility model injection mold location bullet piece core-pulling mechanism matched moulds view;
Fig. 2 is the utility model injection mold location bullet piece core-pulling mechanism die opening state schematic diagram.
The specific embodiment
The utility model relates to a kind of injection mold location bullet piece core-pulling mechanism, as Fig. 1, shown in Figure 2, comprise mould solid plate 1 and moving platen 2, the plastic product 3 that moulding is arranged between solid plate and the moving platen, one side of plastic product 3 matches with the bullet piece 4 of loosing core, it is characterized in that being shaped on counterbore 5 in the described bullet piece 4 of loosing core, screw 6 is arranged in the counterbore, screw 6 passes counterbore and connects solid plate 1, and screw 6 outer walls are equipped with spring 7, and of spring 7 contacts with counterbore 5, the other end of spring 7 contacts with solid plate 1, pressing plate 8 is installed in solid plate 1, is shaped on oblique chute 9 in the pressing plate, the lateral wall of the bullet piece 4 of loosing core matches with oblique chute 9.During the demoulding, moving platen 2 is driven by injection machine power and moves downward, sway in synchrony under the elastic force effect of spring 7 template 5 of the bullet piece 4 of loosing core outwards moves downward along oblique chute 9, the bullet piece 4 of loosing core is disengaged with plastic product 3, after sliding into certain distance, the counterbore 5 of loosing core in the bullet piece 4 contacts with screw 6, the bullet piece 4 of loosing core is held by screw 6 and is no longer moved downward, and moving platen 2 continues to move downward, be with plastic product 3 from the solid plate 1 and the bullet piece 4 of loosing core, to deviate from fully, ejecting mechanism by mould ejects plastic product outside the mould at last, and the demoulding is finished.This programme adopts the spring top to play block mode, and what spring was upspring looses core apart from little, can improve the compactedness of mould, increases the intensity of mould, long service life, and bullet piece handling ease is easy for installation simultaneously, and expense is low, saves cost.Wearing plate 10 is installed on the described moving platen 2, and wearing plate 10 touches with the bottom connection of the bullet piece 4 of loosing core, and anti-template has been arranged, and moving platen does not does not wear and tear, and wearing plate plays upwards to compress the bullet piece of loosing core simultaneously.Be equipped with drag hook 11 on the described moving platen 2, the bottom of the bullet piece 4 of loosing core is shaped on hook groove 12, and drag hook 11 matches with hook groove 12, and during die sinking, drag hook moves downward, drive the bullet piece of loosing core along oblique chute outwards to lower slider, loose core bullet piece and plastic product are disengaged.
