Abstract
The utility model discloses a core-pulling mechanism simple in structure. The core-pulling mechanism simple in structure comprises a front cavity, a rear core, a sliding block core, an insert pin, a return spring, a swinging plate and a return pin, wherein the sliding block core is arranged in a cavity between the front cavity and the rear core in a transverse direction; the insert pin perforates through the rear core in a vertical direction; the inner end of the insert pin perforates in or retracts from the cavity and then is clamped or released from a groove of the sliding block core; the outer end of the insert pin perforates out of the rear core and is propped against the swinging plate with the middle part which is hinged with the bottom surface of the rear core; the other end of the swinging plate is propped against the outer end of the return pin which movably perforates in the rear core; the outer section of the insert pin is sleeved by the return spring. Since the insert pin is driven to move up and down due to the driving of the return spring and the up-and-down movement of the return pin, the insert pin is clamped with the sliding block core and released from the sliding block core. The core-pulling mechanism has the advantages of reliable action and simple structure.
Description
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of core-pulling mechanism simple in structure.
Background technology
Plastic injection mould is the instrument of producing plastic products, applies very extensive.In plastic products injection moulding, because there are side opening or indent in the inside of some plastic products, plastic part cannot take out from mold cores after moulding.The method solving is at present to adopt moving core, and after plastic part moulding, moving core takes out together with plastic part from mould, and then tries every possible means core to take out.This method is time-consuming, effort, cannot meet mass-produced requirement.
Utility model content
The purpose of this utility model is to provide a kind of reliable in action, core-pulling mechanism simple in structure.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of core-pulling mechanism simple in structure, and it comprises front mould, rear mold, slide block fuse, pin, back-moving spring, pendulum plate, reset pin; Described slide block fuse is along being horizontally installed in the die cavity between front mould and rear mold, described pin is longitudinally located in rear mold, the inner of pin penetrates or exits holding after die cavity or deviates from the groove of slide block fuse, the outer end of pin passes one end that rear mold and middle part be hinged on the pendulum plate of rear mold bottom surface and leans, and the other end of pendulum plate leans with the outer end that is actively located in the reset pin in rear mold; Described back-moving spring is socketed in outer section of pin, and the two ends of back-moving spring lean respectively on the countersunk head of section outside rear mold bottom surface and pin.
The utility model also comprises oil cylinder, and the outer end of described slide block fuse is connected with the piston rod of oil cylinder by core-pulling mechanism, and the cylinder body of oil cylinder is fixed on the outer wall of rear mold.
Adopt after such scheme, because the utility model comprises pin, back-moving spring, pendulum plate, reset pin, drive and the moving up and down of the pin that resets by back-moving spring, driving pin moves up and down, realize pin and the holding of slide block fuse and disengaging, the utlity model has reliable in action, advantage simple in structure.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Brief description of the drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is matched moulds state diagram of the present utility model;
Fig. 3 is die opening state figure of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is a kind of core-pulling mechanism simple in structure, and it comprises front mould 1, rear mold 2, oil cylinder 3, slide block fuse 4, pin 5, back-moving spring 6, pendulum plate 7, reset pin 8.
Described slide block fuse 4 is along being horizontally installed in the die cavity between front mould 1 and rear mold 2, and the outer end of slide block fuse 4 is connected with the piston rod of oil cylinder 3 by core-pulling mechanism 9, and the cylinder body of oil cylinder 3 is fixed on the outer wall of rear mold 2; Described pin 5 is longitudinally located in rear mold 2, the inner of pin 5 penetrates or exits holding after die cavity or deviates from the groove of slide block fuse 4, the outer end of pin 5 passes rear mold 2 and leans with one end that middle part is hinged on the pendulum plate 7 of rear mold 2 bottom surfaces, and the other end of pendulum plate 7 leans with the outer end that is actively located in the reset pin 8 in rear mold 2; Described back-moving spring 6 is socketed in outer section of pin 5, and the two ends of back-moving spring 6 lean respectively on the countersunk head 51 of outer section of rear mold 2 bottom surfaces and pin 5.
Operation principle of the present utility model:
1, as shown in Figure 3, when die sinking, when front mould 1 separates with rear mold 2, rear mold 2 pins 5 retreat pin 5 under back-moving spring 6 effects, and pin 5 departs from slide block fuse 4; By oil cylinder 3(as shown in Figure 1) band movable slider fuse 4 retreats; Ejecting product.
2, as shown in Figure 2, when matched moulds, oil cylinder 3(is as shown in Figure 1) first slide block fuse 4 is pushed, to avoid pin 5 and slide block fuse 4 to collide, now, act on rear mold 2 pins 5 are pushed to original position by the reset pin 8 that is arranged on front mould 1.
Emphasis of the present utility model is just: adopt the lever construction being mainly made up of pendulum plate.
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
