Technical Field
[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for the production and processing of electronic product accessories. Background Technology
[0002] Injection molds are tools used for molding and processing plastic products. They are key equipment in the injection molding process. Among them, injection molds for electronic product parts manufacturing refer to injection molding tools specifically used for manufacturing electronic product parts. They form plastic products of specific shapes and sizes by injecting molten plastic into the mold cavity and then cooling and solidifying it.
[0003] In the production and processing of electronic product components, the injection molds used have the drawback of cumbersome mold change procedures. This drawback makes it difficult to quickly change molds according to needs during actual production, which in turn greatly increases downtime, severely restricts production efficiency, and makes it impossible to effectively improve it. At the same time, the flexibility of the production line is also greatly reduced, making it difficult to adapt to diverse production needs. Utility Model Content
[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the mold changing process of injection molds is complicated when producing electronic product accessories, which makes it difficult to quickly change molds to meet the requirements and increases downtime. To this end, we propose an injection mold for the production and processing of electronic product accessories.
[0005] To achieve the above objectives, this application adopts the following technical solution: an injection mold for manufacturing and processing electronic product accessories, comprising an injection mold base, a pressing seat fixedly connected to the top of the injection mold base, an mounting seat fixedly connected to the top of the injection mold base, an mounting groove provided inside the mounting seat, a template installed inside the mounting groove, square grooves provided on both sides of the template, a first spring fixedly connected inside the square groove, a connecting block fixedly connected to the other end of the first spring, one side of the connecting block slidably connected to the inside of the square groove, through grooves provided on both sides of the mounting seat, the surface of the connecting block slidably connected to the inside of the through groove, a push rod slidably connected to the inside of the through groove, a push plate fixedly connected to one end of the push rod, the surface of the push plate slidably connected to the inside of the through groove, and pull grooves provided on both sides of the template.
[0006] Preferably, both ends of the mounting base are provided with sliding grooves, and an irregularly shaped plate is slidably connected inside the sliding groove, with one end of the irregularly shaped plate slidably connected to the inside of the mounting groove.
[0007] Preferably, a limiting piece is fixedly connected to the surface of the connecting block, and the surface of the limiting piece is slidably connected to the interior of the square groove.
[0008] Preferably, a second spring is slidably connected to the surface of the push rod, one end of the second spring is fixedly connected to the push plate, and the other end of the second spring is fixedly connected to one side of the through groove.
[0009] Preferably, guide grooves are provided at the top and bottom of the surface of the push rod, and guide blocks are fixedly connected to the top and bottom of one side of the through groove. The surface of the guide block is slidably connected to the inside of the wear-resistant wheel.

[0011] Preferably, a rubber pad is installed at the bottom end of the irregularly shaped plate.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, pressing the push rod causes it to push the push plate, which in turn pushes the connecting block out of the through slot. At this point, the template is released from its internal limit within the mounting base, allowing it to be moved out. When it is necessary to connect the mounting base and the template, pressing the connecting block causes it to enter the square slot. The template is then placed inside the mounting base. After releasing the pressure on the connecting block, the elasticity of the first spring automatically pushes the connecting block into the through slot, confining the template inside the mounting base. This design allows for quick mold changes and reduced downtime, improving production efficiency and increasing production line flexibility. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: an injection mold for manufacturing and processing electronic product accessories, including an injection mold base 1, a lower pressure seat 2 fixedly connected to the top of the injection mold base 1, an mounting seat 3 fixedly connected to the top of the injection mold base 1, an mounting groove 4 opened inside the mounting groove 4, a template 5 installed inside the mounting groove 4, square grooves 6 opened on both sides of the template 5, a first spring 7 fixedly connected inside the square groove 6, a connecting block 8 fixedly connected to the other end of the first spring 7, one side of the connecting block 8 slidably connected to the inside of the square groove 6, through grooves 9 opened on both sides of the mounting seat 3, the surface of the connecting block 8 slidably connected to the inside of the through groove 9, a push rod 10 slidably connected inside the through groove 9, a push plate 11 fixedly connected to one end of the push rod 10, and the push plate 11... The template 5 is slidably connected to the inside of the through groove 9. Both sides of the template 5 are provided with pull grooves 12. By pressing the push rod 10, the push rod 10 pushes the push plate 11, which pushes the connecting block 8 out of the inside of the through groove 9. At this time, the limiting position of the template 5 inside the mounting base 3 is released, and the template 5 can be moved out of the inside of the mounting base 3. When it is necessary to connect the mounting base 3 and the template 5, press the connecting block 8, so that the connecting block 8 enters the inside of the square groove 6, and place the template 5 inside the mounting base 3. Then release the pressure on the connecting block 8, and the elasticity of the first spring 7 automatically pushes the connecting block 8 into the inside of the through groove 9, so that the template 5 is restricted inside the mounting base 3. With this setting, quick mold change can be achieved as needed, downtime can be reduced, production efficiency can be improved, and production line flexibility can be enhanced.
[0022] Reference Figure 5As shown in this embodiment: sliding grooves 13 are provided at both ends of the mounting base 3. A shaped plate 14 is slidably connected inside the sliding groove 13. One end of the shaped plate 14 is slidably connected to the inside of the mounting groove 4. By setting the shaped plate 14, when the limit of the template 5 in the mounting base 3 is released, the end of the shaped plate 14 located outside the mounting base 3 is lifted, so that the shaped plate 14 located inside the mounting groove 4 lifts the template 5, so that the template 5 can be lifted upward, making it convenient for the staff to take the template 5 out of the inside of the mounting groove 4, providing convenience for the staff.
[0023] Reference Figure 4 As shown in this embodiment: the surface of the connecting block 8 is fixedly connected to the limiting piece 15, and the surface of the limiting piece 15 is slidably connected to the inside of the square groove 6. By setting the limiting piece 15, the movement position of the connecting block 8 can be effectively restricted, and one end of the connecting block 8 is prevented from coming out of the inside of the square groove 6 due to the elasticity of the first spring 7, thus ensuring the stability of the connection between the template 5 and the mounting base 3.
[0024] Reference Figure 3 As shown in this embodiment: a second spring 16 is slidably connected to the surface of the push rod 10. One end of the second spring 16 is fixedly connected to the push plate 11, and the other end of the second spring 16 is fixedly connected to one side of the through groove 9. By setting the second spring 16 on the surface of the wear-resistant rotating wheel 19, the elasticity of the second spring 16 is connected to the push plate 11. When the operator releases the push rod 10, the elasticity of the second spring 16 drives the push plate 11, and the push plate 11 drives the push rod 10 to reset. There is no need for the operator to manually reset, which provides convenience for the next use.
[0025] Reference Figure 3 As shown in this embodiment: guide grooves 17 are provided at the top and bottom of the surface of the push rod 10, and guide blocks 18 are fixedly connected to the top and bottom of one side of the through groove 9. The surface of the guide block 18 is slidably connected to the inside of the wear-resistant rotating wheel 19. By making the guide block 18 slide inside the wear-resistant rotating wheel 19, the movement of the push rod 10 can be guided, and the push rod 10 can be prevented from shaking when it drives the push plate 11 to move.
[0026] Reference Figure 5 As shown in this embodiment: wear-resistant rollers 19 are installed on both sides of the irregular plate 14. The surface of the wear-resistant rollers 19 is rotatably connected to both sides inside the sliding groove 13. By setting the irregular plate 14, the friction between the irregular plate 14 and the sliding groove 13 can be effectively reduced, making the irregular plate 14 lift the template 5 more smoothly.
[0027] Reference Figure 5As shown in this embodiment: a rubber pad 20 is installed at the bottom of the irregular plate 14. By installing the rubber pad 20, it can effectively prevent the irregular plate 14 from falling rapidly and colliding with the bottom of the mounting groove 4 when the worker releases the lifting of the irregular plate 14, thereby generating noise. At the same time, it provides protection for the bottom of the irregular plate 14.
[0028] Working principle: By pressing the push rod 10, the push rod 10 pushes the push plate 11, causing the push plate 11 to push the connecting block 8 out of the through groove 9. At this time, the limiting position of the template 5 inside the mounting base 3 is released, and the template 5 can be moved out of the mounting base 3. When it is necessary to connect the mounting base 3 and the template 5, press the connecting block 8, causing the connecting block 8 to enter the square groove 6. Place the template 5 inside the mounting base 3, and then release the pressure on the connecting block 8. The elasticity of the first spring 7 automatically pushes the connecting block 8 into the through groove 9, causing the template 5 to be pushed out of the through groove 9. Template 5 is confined inside mounting base 3. This design allows for quick mold changes and reduced downtime, improving production efficiency and production line flexibility. By using the shaped plate 14, when the limiting position of template 5 within mounting base 3 is released, lifting the end of the shaped plate 14 outside mounting base 3 causes the end of the shaped plate 14 inside mounting groove 4 to lift template 5, allowing it to be lifted upwards. This facilitates the removal of template 5 from inside mounting groove 4 by workers, providing convenience. The limiting piece 15 effectively restricts the connection... The movement of block 8 prevents one end of the connecting block 8 from detaching from the inside of the square groove 6 due to the elasticity of the first spring 7, ensuring the stability of the connection between the template 5 and the mounting base 3. A second spring 16 is provided on the surface of the wear-resistant rotating wheel 19. The rebound of the second spring 16 is transmitted through the connecting push plate 11. When the operator releases the pressure on the push rod 10, the rebound of the second spring 16 drives the push plate 11, which in turn drives the push rod 10 to reset. This eliminates the need for manual reset by the operator, providing convenience for the next use. This is achieved by allowing the guide block 18 to move within the wear-resistant rotating wheel... The internal sliding of the wheel 19 can guide the movement of the push rod 10, preventing the push rod 10 from shaking when it drives the push plate 11 to move. By setting the irregular plate 14, the friction between the irregular plate 14 and the sliding groove 13 can be effectively reduced, making the movement of the template 5 by the irregular plate 14 smoother. By installing the rubber pad 20, it can be effectively prevented from falling rapidly and colliding with the bottom of the mounting groove 4 when the worker releases the lifting of the irregular plate 14, thus generating noise. At the same time, it provides protection for the bottom of the irregular plate 14.
