Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold that facilitates material discharge. Background Technology

[0002] Elastic grinding blocks are grinding tools made of polyurethane or other elastic materials through mold pressing. They have three functions: bearing, cutting, and polishing. They are widely used in many industries such as pharmaceuticals, food, chemicals, and metal processing. They are particularly suitable for crushing granular materials, as well as metal surface polishing, ultra-precision machining, and mold processing. Molten plastic is injected into the mold cavity under high pressure by an injection molding machine. After cooling and solidification by the injection mold, the elastic grinding block is obtained. However, existing injection molds have the disadvantage of being inconvenient to eject material. It is not convenient to eject the elastic grinding block at the same time as the mold is opened, which can easily damage the molded material. Utility Model Content

[0003] The purpose of this utility model is to provide an injection mold that facilitates material discharge, thereby solving the problem mentioned in the background art that existing injection molds are inconvenient for material discharge, making it difficult to eject the elastic grinding block at the same time as mold opening, which can easily damage the molded material.

[0026] Please see Figures 1 to 4 This utility model provides a technical solution: an injection mold for easy material discharge, comprising: a support base 1, a sliding base 3, a moving mold 4, a second support side frame 5, a support side plate 6, a fixed mold 7, a limiting ejector frame 9, an ejector column 10, an inner ejector plate 11, and an ejector pin 14. The sliding base 3 is slidably disposed on the top of the support base 1; the moving mold 4 is fixedly connected to the top of the sliding base 3; the second support side frame 5 is symmetrically fixedly connected to one side of the moving mold 4, and the bottom of the second support side frame 5 is fixedly connected to the sliding base 3; the support side plate 6 is fixedly connected to one side of the second support side frame 5, and the bottom of the support side plate 6 is fixedly connected to the sliding base 3; the fixed mold 7 is fixedly connected to the top of the support base 1; the inner top plate 11 is slidably disposed on the inner side of the second support side frame 5; the ejector pins 14 are symmetrically slidably disposed inside the moving mold 4, and one end of the ejector pins 14 is fixedly connected to the inner top plate 11; the ejector pin 10 is fixedly connected to one side of the inner top plate 11, and the ejector pin 10 is slidably connected to the support side plate 6; the limiting ejector 9 is fixedly connected to the top of the support base 1, and the limiting ejector 9 cooperates with the ejector pin 10.

[0027] It is understood that this utility model controls the device through an external controller and powers it through an external power supply. The output end of the hydraulic cylinder 15 drives the sliding plate 18 to move on the first support side frame 2. The output end of the hydraulic cylinder 15 pushes the sliding plate 18 to move. When the sliding plate 18 moves, it drives the fixed rod 17 to move. When the fixed rod 17 moves, it pushes the support side plate 6, the second support side frame 5, the moving mold 4, and the sliding base 3 to move and adjust on the support base 1, so that the moving mold 4 and the fixed mold 7 are closed. Injection molding is performed through one side of the fixed mold 7. After cooling and forming in the moving mold 4 and the fixed mold 7, when demolding and material removal are required, the hydraulic cylinder 15... The output end pulls the sliding plate 18, fixed rod 17, support side plate 6, second support side frame 5, moving mold 4 and sliding base 3 outward. The moving mold 4 moves away from the fixed mold 7 to complete the mold opening. When the ejector 10 touches one side of the limit ejector 9, it continues to move. At this time, the limit ejector 9 pushes the ejector 10 to move closer to the moving mold 4. The ejector 10 pushes the inner ejector plate 11 and ejector pin 14 to move. The ejector pin 14 ejects the molding material in the moving mold 4. When the inner ejector plate 11 moves, it squeezes the spring 13 on the outside of the first limit slide rod 12. When the moving mold 4 and the fixed mold 7 reclose, the spring 13 will reset and drive the inner ejector plate 11 and each ejector pin 14 to complete the reset.

[0028] Please see Figures 1 to 4 The injection mold for easy material discharge also includes a first support side frame 2, which is fixedly connected to one side of the support base 1. A hydraulic cylinder 15 is installed on one side of the first support side frame 2, and a sliding plate 18 is slidably arranged on the top of the first support side frame 2. The output end of the hydraulic cylinder 15 is fixedly connected to the sliding plate 18. A fixing rod 17 is symmetrically fixedly connected to one side of the sliding plate 18, and one end of the fixing rod 17 is fixedly connected to the support side plate 6.

[0029] It is understood that in this utility model, the sliding plate 18 slides on the first support side frame 2, and the output end of the hydraulic cylinder 15 drives each fixed rod 17 to move through the sliding plate 18. When the fixed rod 17 moves, it drives the support side plate 6, the second support side frame 5, the moving mold 4 and the sliding base 3 to be adjusted synchronously, and performs mold opening and closing adjustment processing on the moving mold 4 and the fixed mold 7.

[0030] Please see Figures 1 to 4 The top of the support base 1 is fixedly connected to the support top plate 8, the fixing rod 17 is slidably connected to the support top plate 8, and one side of the limiting top frame 9 is fixedly connected to the support top plate 8.

[0031] It is understood that this utility model ensures the stability of the adjustment of the fixed rod 17 and the supporting side plate 6 by limiting the sliding of the fixed rod 17 on one side when the sliding plate 18 drives the fixed rod 17 to move.

[0032] Please see Figures 1 to 4The inner top plate 11 has a first limiting slide rod 12 that is slidably installed inside. One end of the first limiting slide rod 12 is fixedly connected to the moving mold 4, and the other end of the first limiting slide rod 12 is fixedly connected to the supporting side plate 6. A spring 13 is sleeved on the outside of the first limiting slide rod 12.

[0033] It is understood that this utility model uses the spring 13 on the outside of the first limiting slide bar 12 to be squeezed when the inner top plate 11 moves. When the moving mold 4 and the fixed mold 7 re-close, the spring 13 will reset and drive the inner top plate 11 and each ejector pin 14 to complete the reset.

[0034] Please see Figures 1 to 4 The first support side frame 2 is symmetrically equipped with a second limiting slide rod 16 inside, and one end of the second limiting slide rod 16 is fixedly connected to the sliding plate 18.

[0035] It is understood that this utility model improves the stability of the sliding plate 18 during adjustment by moving and adjusting the sliding plate 18 through the output end of the hydraulic cylinder 15. When the sliding plate 18 moves and adjusts, it drives the second limiting slide rod 16 on one side to move. The second limiting slide rod 16 slides and limits the sliding with the first support side frame 2.
