[0028] In the description of the present utility model, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0029] Please refer to Figure 1-6As shown, the utility model is a tooling fixture for injection molding production and installation of inserts, including a fixed plate 1, a fixed plate 2 and a movable plate 3 parallel to the horizontal plane, the movable plate 3 is arranged between the fixed plate 1 and the fixed plate 2, the bottom surface of the fixed plate 1 is provided with a plurality of evenly distributed fixed columns 6, the fixed columns 6 penetrate the fixed plate 2 and are fixedly connected to the fixed plate 2, and a detachable contact head 9 which is in the same plumb line as the axis of the fixed column 6 is arranged below the fixed columns 6, the fixed plate 2 is also penetrated by a plurality of evenly distributed insert placement tubes 4 and is fixedly connected to the insert placement tube 4, and the bottom end of the movable plate 3 is fixedly provided with a contact head 9 which cooperates with the insert placement tube 4 The push rod 5 passes through the top of the insert placement tube 4 and is slidably connected with the insert placement tube 4. A holding handle 101 is provided on one side of the fixed plate 1. In this embodiment, the insert placement tube 4 is used to place the insert. The movement of the movable plate 3 can drive the push rod 5 to move downward to eject the insert. The distance from the end of the detachable contact head 9 away from the movable plate 3 to the movable plate 3 is slightly larger than the distance from the end of the insert placement tube 4 away from the movable plate 3 to the movable plate 3. When using the tooling fixture, the detachable contact head 9 first contacts the mold to prevent collision between the insert placement tube 4 and the mold. If the detachable contact head 9 is worn, the detachable contact head 9 can be removed for replacement.

[0030] Among them, a smooth groove 601 is opened upward on the bottom surface of the fixed column 6, and the bottom end of the smooth groove 601 is penetrated by the top end of the connecting column 8 and is slidably connected with the connecting column 8. An external thread section 801 is provided at the lower end of the outer wall of the connecting column 8, and an internal thread groove 901 is opened downward on the top surface of the detachable contact head 9. The bottom end of the connecting column 8 penetrates the internal thread groove 901 and the external thread section 801 is threadedly connected with the internal thread groove 901. In this embodiment, the detachable contact head 9 is threadedly connected to the connecting column 8 through the cooperation of the internal thread groove 901 and the external thread section 801, and can be quickly disassembled and replaced after the detachable contact head 9 is damaged.

[0031] Among them, the top surface of the smooth groove 601 is fixedly connected to one end of the hydraulic shock absorber 7, and the other end of the hydraulic shock absorber 7 is fixedly connected to the top of the connecting column 8. In this embodiment, when the detachable contact head 9 collides with the mold, the hydraulic shock absorber 7 will be deformed. The hydraulic shock absorber 7 has a buffering effect on the detachable contact head 9, preventing the detachable contact head 9 from a rigid collision with the mold and reducing the impact force on the detachable contact head 9. When the hydraulic shock absorber 7 is compressed to the shortest, the distance from the end of the detachable contact head 9 away from the movable plate 3 to the movable plate 3 is still slightly larger than the distance from the end of the insert placement tube 4 away from the movable plate 3 to the movable plate 3.

[0032] Among them, the moving plate 3 is penetrated by the fixing column 6 and is slidably connected to the fixing column 6. A smooth column 10 is fixedly arranged at the top end of the moving plate 3. The smooth column 10 penetrates through the first fixing plate 1 and is slidably connected to the first fixing plate 1. A pressing handle 11 is fixedly arranged at the top end of the smooth column 10. A first return spring 12 is sleeved outside the ejector rod 5. The two ends of the first return spring 12 are respectively fixedly connected to the second fixing plate 2 and the moving plate 3. In this embodiment, pressing the pressing handle 11 drives the moving plate 3 to move downward. The downward movement of the moving plate 3 drives the ejector rod 5 to move downward to eject the insert. The fixing column 6 plays a guiding role in the movement of the moving plate 3 to ensure the smooth movement of the moving plate 3. After the insert is ejected and the pressing handle 11 is released, the first return spring 12 drives the moving plate 3 to reset.

[0033] Among them, a second return spring 13 is sleeved outside the fixing column 6. The two ends of the second return spring 13 are respectively fixedly connected to the second fixing plate 2 and the moving plate 3. After the pressing handle 11 is released, the second return spring 13 will also generate elastic force to drive the moving plate 3 to reset together with the first return spring 12. The second return spring 13 can also strengthen the connection between the moving plate 3 and the second fixing plate 2.

[0034] It can be understood that, firstly, the detachable contact head 9 of the present utility model is threadedly connected to the connecting column 8 through the cooperation of the internal thread groove 901 and the external thread section 801, and can be quickly disassembled and replaced after the detachable contact head 9 is damaged. Secondly, the fixing column 6 used to connect the first fixing plate 1 and the second fixing plate 2 plays a guiding role in the movement of the moving plate 3 to ensure the smooth movement of the moving plate 3.

[0035] A specific application of this embodiment is as follows: The user first places the insert in the insert placing cylinder 4, then holds the tooling fixture by holding the handle 101, and then moves the tooling fixture close to the mold. The detachable contact head 9 first contacts the mold to prevent collision between the insert placing cylinder 4 and the mold. When the detachable contact head 9 contacts the mold, the hydraulic shock absorber 7 will deform. The hydraulic shock absorber 7 plays a buffering role for the detachable contact head 9 to prevent rigid collision between the detachable contact head 9 and the mold and reduce the impact force received by the detachable contact head 9. The detachable contact head 9 is threadedly connected to the connecting column 8 through the cooperation of the internal thread groove 901 and the external thread section 801 and can be quickly disassembled and replaced after the detachable contact head 9 is damaged. After the tooling fixture is placed in the appropriate position, the user presses the pressing handle 11 to drive the moving plate 3 to move downward close to the second fixing plate 2. The downward movement of the moving plate 3 drives the ejector rod 5 to move downward to eject the insert. The fixing column 6 plays a guiding role in the movement of the moving plate 3 to ensure the smooth movement of the moving plate 3. After the insert is ejected and the pressing handle 11 is released, the first return spring 12 and the second return spring 13 drive the moving plate 3 to reset.
