Description

Technical Field

[0001] The invention belongs to the technical field of metal casting, and in particular relates to a copper product demoulding device. Background Art

[0002] The existing Chinese patent database discloses a patent named "A Coil Spring Controlled Die Casting Machine", application number CN202210306797.2, application date 2022-03-25, a coil spring controlled die casting machine, comprising a frame, an injection unit, a workbench and a hot furnace provided on the frame; an injection unit, the injection unit being mounted on the frame, the injection unit being connected to the hot furnace, and being used to supply the casting medium in the hot furnace to the workbench; the present invention controls one end of the slider mold by driving a motor and a coil spring, and when the molded When the casting is stuck in the slider mold, the rotating coil spring is deformed by the extrusion pressure of the U-shaped plate and gradually accumulates force. After deformation to a certain extent, the coil spring detaches from the left side of the U-shaped plate and then resets. When resetting, it hits the U-shaped plate, causing the slider mold to vibrate. By setting up U-shaped plates with different vertical sections, the slider mold vibrates twice, with the first vibration amplitude being smaller and the second vibration amplitude being larger. This can better separate the casting from the slider mold, achieve better demoulding effect, improve the yield rate, and greatly reduce the labor intensity of workers.

[0003] In the demoulding process of the prior art, the speed and force of the ejector pin during its movement remain constant, resulting in insufficient instantaneous impact force when the ejector pin moves to the mold cavity, thereby reducing the demoulding efficiency. Therefore, this scheme aims to propose a copper product demoulding equipment that can perform energy storage operation, increase the instantaneous impact force when the ejector pin is at the bottom of the mold cavity, and improve the demoulding effect. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that in the prior art, the ejection speed and force of the ejector pin during the demoulding process remain constant, resulting in insufficient instantaneous impact force when the ejector pin moves to the mold cavity, thereby reducing the demoulding efficiency. In order to improve its shortcomings, the present invention provides a copper product demoulding device.

[0005] To achieve the above object, the present invention is achieved through the following technical solutions:

[0006] The cam is secured to the upper edge of the second support frame, and the cam is secured to the lower edge of the second support frame by a spring.

[0007] As a preferred solution, the first slide and the second slide are provided with four groups, and are enclosed in a square arrangement. The enclosed push rods are arranged toward the outside of the workbench, the first slide and the second slide are suspended and fixedly connected to the surface of the workbench, a slide groove is provided at the bottom of the first slide, the bottom of the first sliding block extends to the outside of the slide groove, and a shaft is provided at the bottom of the first slide protruding from the slide groove. A rotating disk is rotatably connected to the upper surface of the workbench, and a plurality of swing arms are integrally provided on the outer circumference of the rotating disk, and a first waist-shaped groove is provided on the free end of the swing arm, and each shaft is located in the corresponding first waist-shaped groove. A driving device for controlling the swing of the rotating disk is provided on the lower surface of the workbench.

[0008] As a preferred solution, the limit block includes a connecting section fixedly connected to the second slide, and a second waist-shaped groove is provided on the connecting section. The direction of the second waist-shaped groove is consistent with the length direction of the second slide, and two fixing bolts are inserted in the second waist-shaped groove. A number of connecting holes are spaced apart on the upper surface of the second slide, and the two fixing bolts are screwed to any two adjacent connecting holes.

[0009] As a preferred solution, the first slide is U-shaped, and both ear plate sections of the first slide are integrally provided with inner flanges, and the second slide has the same structure as the first slide.

[0010] As a preferred solution, a guide rod is provided on the inner end surface of the fixing seat, one end of the first compression spring is sleeved on the guide rod, a blind hole is opened on the end surface of the second sliding block, and the other end of the first compression spring is connected to the bottom of the blind hole.

[0011] As a preferred solution, a supporting column is provided at the bottom of the workbench.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Due to the coordinated arrangement of the first sliding block, the second sliding block, the wedge block, and the limit block, the second sliding block squeezes the first compression spring to store energy, which is quickly released when it moves to the limit block, thereby increasing the instantaneous impact force when the ejector moves to the mold cavity, thereby improving the demoulding effect;

[0014] 2. The coordinated setting of the rotating disk and the swing arm utilizes the limited space on the workbench to set up multiple sets of ejector pins, so that the ejection action of multiple sets of ejector pins can be performed synchronously, thus realizing batch demoulding;

[0015] 3. The adjustable setting of the limit block can adjust the compression amount of the first compression spring when the second sliding block moves to the limit block, thereby adjusting the impact force when the ejector rod is ejected and changing the instantaneous speed when the ejector rod moves to the mold cavity, so as to facilitate adaptation and adjustment according to castings of different sizes. This device is suitable for industrial production and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

A second compression spring 12 is sleeved on the screw 11 located in the groove 9, and a locking nut 13 is screwed on the screw 11 outside the second sliding block 5. The wedge surface of the wedge block 10 is set toward the front end of the second slide 3, and a limiting cam 14 is provided on the top of the wedge block 10. A limiting block 15 is provided on the second slide 3. The end face of the limiting block 15 is provided with an inclined surface that contacts the limiting cam 14, and a driving cam 16 for squeezing the wedge block 10 to move along the second slide 3 is provided on the side of the first sliding block 4 facing the second sliding block 5. There are four groups of first slides 2 and second slides 3, which are enclosed in a square shape. The enclosed push rods 6 are all arranged toward the outside of the workbench 1. The first slide 2 and the second slide 3 are suspended and fixedly connected to the surface of the workbench 1. A slide groove 17 is provided at the bottom of the first slide 2. The bottom of the first sliding block 4 extends to the outside of the slide groove 17. A shaft 18 is provided at the bottom of the first slide 2 protruding from the slide groove 17. A rotating disk 19 is rotatably connected to the upper surface of the workbench 1. A plurality of swing arms 20 are integrally provided on the outer peripheral surface of the rotating disk 19. A first waist-shaped groove 21 is provided on the free end of the swing arm 20. Each shaft 18 is located in the corresponding first waist-shaped groove 21. A driving device for controlling the swing of the rotating disk 19 is provided on the lower surface of the workbench 1. The limit block 15 includes a connecting section 22 fixedly connected to the second slide 3. A second waist-shaped groove 23 is provided on the connecting section 22. The direction of the second waist-shaped groove 23 is consistent with the length direction of the second slide 3. Two fixing bolts 24 are inserted into the second waist-shaped groove 23. A plurality of connecting holes 25 are spaced apart on the upper surface of the second slide 3. The two fixing bolts 24 are screwed into any two adjacent connecting holes 25.
