Description

Technical Field

[0001] This application relates to the field of injection molding equipment technology, and specifically to a straightening structure for straightening inserts. Background Technology

[0002] Ejector pins (also known as push pins, ejector pins, or support pins) are common components in injection molds. They are mainly used to create holes, through holes, or blind holes in the product during the injection molding process, or to eject the product for demolding. Existing injection molding machine ejector pins are relatively slender and are easily bent during injection molding. When an ejector pin is bent, it needs to be replaced, which seriously affects the machine's efficiency. Utility Model Content

[0003] To address the problem of bent inserts in existing injection molding machines, this application provides a straightening structure for straightening inserts. The specific technical solution of this application is as follows:

[0004] A straightening structure for straightening a pin includes: an injection-molded component and a pin disposed on the injection-molded component. The straightening structure further includes: a telescopic member, a telescopic cylinder, and a clamp. The clamp is fixedly disposed in the injection-molded component, and the telescopic cylinder is movably disposed in the injection-molded component via the telescopic member. The lower end of the clamp is provided with a jaw-type clamping structure, and the lower end of the jaw-type clamping structure is sleeved on the upper end of the pin. The outer surface of the jaws at the lower end of the clamp is arc-shaped. The telescopic cylinder is sleeved on the lower end of the clamp, and a clamping inclined surface is provided in the telescopic cylinder. When the telescopic cylinder moves up and down under the action of the telescopic member, the jaws at the lower end of the clamp clamp clamp or release the pin under the action of the clamping inclined surface.

[0005] Furthermore, the straightening structure includes a support block and a connecting column. The clamp is fixedly mounted on the support block, and the connecting column passes through the support block, with one end connected to the telescopic cylinder and the other end connected to the telescopic component.

[0006] Furthermore, the support block is provided with screws, and the clamp is fixedly mounted on the support block by the screws.

[0007] Furthermore, the telescopic component is a pneumatic cylinder or a hydraulic cylinder.

[0008] Furthermore, the number of connecting posts is 2, and the connecting posts are located on both sides of the clamp.

[0009] Furthermore, the bottom of the connecting column is provided with a threaded portion, and the connecting column is fixed to the telescopic cylinder through the threaded portion.

[0010] Furthermore, the injection-molded component is provided with a telescopic groove, and the telescopic cylinder is disposed on the telescopic groove. The telescopic cylinder is screw-shaped, and a spring is sleeved on the lower end of the telescopic cylinder. The spring is located between the bottom of the telescopic groove and the telescopic cylinder.

[0011] Furthermore, the jaws of the clamp are provided with teeth, and the upper end of the insert pin is provided with a toothed mating part that mates with the teeth.

[0012] Furthermore, the insert has a diameter of 1.0 mm and a length of 500 mm.

[0013] Compared with existing technologies, the advantages of this application are as follows: The straightening structure described in this application, through the cooperation of a telescopic cylinder and a clamp, utilizes the mechanical action of the clamping inclined surface to quickly and accurately straighten bent inserts. The clamping jaws of the clamp can firmly fix the insert, ensuring that the insert will not slip during the straightening process, thereby improving the reliability and stability of the straightening effect. Because the outer surface of the jaws at the lower end of the clamp is designed as an arc, this structure can evenly distribute pressure when clamping the insert, avoiding damage to the insert due to excessive local pressure, thereby protecting the structural integrity of the insert and extending its service life.

[0025] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of this application, making the technical solution and its beneficial effects clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, but should not be construed as limiting it.

[0026] like Figure 1 and Figure 6As shown, the present invention provides a straightening structure for straightening inserts, which is reasonably designed, easy to operate, and can effectively improve straightening efficiency and accuracy.

[0027] The straightening structure includes the following main components: Injection molded component 1: serving as the main frame of the entire straightening structure and used to fix other components. Insert pin 2: the component to be straightened, mounted on injection molded component 1. Telescopic component 3: providing power to enable the telescopic cylinder 4 to move up and down. Telescopic cylinder 4: connected to telescopic component 3, moving up and down on injection molded component 1 under the action of telescopic component 3. Clamping member 5: used to clamp the insert pin 2, fixedly mounted in injection molded component 1.

[0028] The lower end of the clamping member 5 is provided with a jaw-type clamping structure 6, and the lower end of the jaw-type clamping structure 6 is sleeved on the upper end of the insert pin 2. The telescopic cylinder 4 is sleeved on the lower end of the clamping member 5, and the telescopic cylinder 4 is provided with a clamping inclined surface 7 inside. When the telescopic cylinder 4 moves up and down under the action of the telescopic member 3, the jaws at the lower end of the clamping member 5 clamp or release the insert pin 2 under the action of the clamping inclined surface 7. That is, when the telescopic cylinder 4 moves upward, the clamping inclined surface 7 applies pressure to the jaws, causing the jaws to clamp the insert pin 2; when the telescopic cylinder 4 moves downward, the clamping inclined surface 7 does not apply pressure to the jaws or the pressure applied to the jaws decreases, and the jaws release the insert pin 2. The outer surface of the jaws at the lower end of the clamping member 5 is arc-shaped. This structure can better enable the jaws to cooperate with the clamping inclined surface 7 to clamp the insert pin 2, thereby improving the clamping effect.

[0029] In one embodiment, the straightening structure further includes a support block 8 and a connecting column 9. The clamp 5 is fixedly mounted on the support block 8, and the connecting column 9 passes through the support block 8, with one end connected to the telescopic cylinder 4 and the other end connected to the telescopic component 3. This design makes the entire straightening structure more stable and also facilitates the connection and transmission between the components.

[0030] In one embodiment, the support block 8 is provided with screws 10, and the clamp 5 is fixedly mounted on the support block 8 by the screws 10. This fixing method is simple and reliable, and facilitates the disassembly and replacement of the clamp 5.

[0031] In one embodiment, the telescopic member 3 is a pneumatic cylinder or a hydraulic cylinder. The pneumatic or hydraulic cylinder provides stable power, ensuring smooth and reliable up-and-down movement of the clamp 5.

[0032] In one embodiment, the number of connecting posts 9 is two, and the connecting posts 9 are located on both sides of the clamp 5. This design can better balance the force on the clamp 5 and improve the stability of the straightening process.

[0033] In one embodiment, the bottom of the connecting post 9 is provided with a threaded portion 11, and the connecting post 9 is fixed to the telescopic cylinder 4 through the threaded portion 11. The threaded connection method is simple and reliable, and facilitates installation and disassembly.

[0034] In one embodiment, the injection-molded component 1 is provided with a telescopic groove 12, and the telescopic cylinder 4 is disposed on the telescopic groove 12. The telescopic cylinder 4 is screw-shaped, and a spring 13 is sleeved on the lower end of the telescopic cylinder 4. The spring 13 is located between the bottom of the telescopic groove 12 and the telescopic cylinder 4. The design of the spring 13 can provide a certain buffering effect to prevent excessive pressure on the insert pin 2 during the straightening process, thereby protecting the insert pin 2 from damage. The spring 13 also generates a thrust on the telescopic cylinder 4, increasing the pressure of the clamping inclined surface 7 of the telescopic cylinder 4 on the jaws, so that the jaws firmly clamp the insert pin 2, improving the straightening effect of the insert pin 2.

[0035] In one embodiment, the jaws of the clamp 5 are provided with teeth 14, and the upper end of the insert pin 2 is provided with a toothed mating part 15 that mates with the teeth 14. This design can further enhance the friction between the clamp 5 and the insert pin 2, ensuring a more reliable clamping effect, and also helps to improve the straightening accuracy.

[0036] The straightening structure of this invention, through its unique design, effectively solves the problem of the insert pin 2 being easily bent and difficult to repair during use in injection molding machines, significantly improving the working efficiency of the injection molding machine and the service life of the insert pin 2. Specific technical effects are as follows:

[0037] 1. Through the cooperation of the telescopic cylinder 4 and the clamp 5, and utilizing the mechanical action of the clamping inclined plane 7, the bent insert 2 can be straightened quickly and accurately. The jaw clamping structure 6 of the clamp 5 can firmly fix the insert 2, ensuring that the insert 2 will not slip during the straightening process, thereby improving the reliability and stability of the straightening effect.

[0038] 2. Because the outer surface of the jaws at the lower end of the clamp 5 is designed to be arc-shaped, this structure can evenly distribute pressure when clamping the insert 2, avoiding damage to the insert 2 due to excessive local pressure, thereby protecting the structural integrity of the insert 2 and extending its service life.

[0039] 3. Traditional injection molding machines typically require downtime to replace the insert 2 after it is bent, which not only wastes time but may also delay production. The straightening structure of this invention can repair the insert 2 without stopping the machine, reducing downtime caused by insert 2 replacement and significantly improving the production efficiency of the injection molding machine.

[0040] 4. This straightening structure is suitable for various specifications of insert pins 2, exhibiting good versatility and adaptability. Whether the insert pin 2 is slender or thicker, effective straightening can be achieved by adjusting the positions of the telescopic cylinder 4 and the clamping piece 5, meeting the needs of different injection molds.

[0041] In summary, the straightening structure of the present invention provides an efficient, reliable and economical solution for the repair of the insert 2 in the injection molding machine, and has significant technical effects and practical value.
