Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for a connector plastic housing. Background Technology

[0002] Injection molds generally refer to injection molding, also known as injection molding. It is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, and automated operation.

[0003] A connector plastic housing injection mold with Chinese patent publication number CN220593947U includes a worktable with a placement groove on its top. Support plates are symmetrically connected to the top of the worktable. A lower mold is connected to one side of one support plate, and a hydraulic cylinder is mounted on one side of the other support plate. A hydraulic rod is connected to one end of the hydraulic cylinder, and one end of the hydraulic rod passes through the support plate and is connected to an upper mold. An ejection assembly is installed between one side of the injection molding machine and the lower mold. The ejection assembly includes a bearing installed on one side of the injection molding machine. A screw is rotatably connected to one side of the bearing, and a movable plate is threaded onto the outer wall of the screw. Rods are symmetrically connected to one side of the movable plate, and one end of each rod passes through the lower mold and is connected to a push block.

[0004] In the aforementioned device, when removing the finished product from the two mold cavities, it is necessary to manually twist the screw to make the screw rotate through the bearing, so that the movable plate moves on the screw, thereby driving the push block to move into the two mold cavities of the lower mold through the two rods, so that the push block pushes the finished product out of the mold cavity and into the placement groove. This method requires manual operation and is inefficient.

[0022] First Embodiment

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of the connector plastic housing injection mold provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the outer shell. Figure 3 for Figure 2 The rear view of the casing shown; Figure 4 for Figure 3A partial enlarged view of A is shown. The connector plastic housing injection mold includes a workbench 1. Mounting plate 1 (2) and mounting plate 2 (3) are respectively installed at the left and right ends of the top of the workbench 1. The mold 1 (4) is installed on the right outer wall of mounting plate 1 (2). Circular grooves 19 are formed at both the top and bottom of the right outer wall of mold 1 (4). A rectangular groove 23 is formed inside the left end of mold 1 (4). Two sets of circular grooves 19 are connected to round rods 6. The left ends of the two sets of round rods 6 extend into the rectangular groove 23. A connecting plate 21 is installed between the left ends of the two sets of round rods 6. Circular blocks 7 are installed at the right ends of the two sets of round rods 6. A limiting plate 26 is installed on the outer wall of the two sets of round rods 6. A spring 20 is installed between the left end of the limiting plate 26 and the left inner wall of the circular groove 19. The spring 20 is sleeved on the outside of the round rod 6. Two sets of push rods 2 are installed on the right side wall of the connecting plate 21. 4. The push rod 24 is slidably connected to the groove inside the mold 4. An injection molding machine device 13 is installed on the outer wall of the left end of the mounting plate 2. An injection molding tube 22 is installed between the injection molding machine device 13 and the groove inside the mold 4. A cylinder 12 is installed on the outer wall of the right end of the mounting plate 3. The output end of the cylinder 12 passes through the mounting plate 3 and the output end of the cylinder 12 is installed on the mold 5. Both the upper and lower ends of the outer wall of the left end of the mold 5 are equipped with protrusions 14. A rectangular opening 27 is opened at the top of the workbench 1. The rectangular opening 27 passes through the bottom and front side wall of the workbench 1. Two sets of sliding grooves 10 are opened on the front side wall of the workbench 1. The sliding grooves 10 are connected to the rectangular opening 27. Sliding strips 15 are slidably connected to the inner walls of the two sets of sliding grooves 10. A collection frame 11 is installed between the two sets of sliding strips 15. Several sets of air holes are opened at the bottom of the collection frame 11.

[0024] A mounting plate 25 is installed on the bottom of the workbench 1 near the lower end of the rectangular opening 27. A cooling component 17 is installed on the mounting plate 25, which automatically cools the products inside the collection box 11.

[0025] The cooling component 17 includes a motor 171, which is fixedly installed at the bottom of the mounting plate 25. The output end of the motor 171 extends through to the upper end of the mounting plate 25, and a fan 172 is installed at the output end of the motor 171. The output end of the motor 171 drives the fan 172 to rotate continuously, and the generated airflow continuously enters the collection frame 11 through the air hole. After contacting the product, it cools it down.

[0026] Two sets of guide rods 8 are installed between the mounting plate 1 2 and the mounting plate 2 3. Slider 9 is installed on the front and rear outer walls of the mold 2 5. The slider 9 is slidably connected to the guide rod 8. When the cylinder 12 pushes the mold 2 5 to move left and right, the slider 9 can make the mold 2 5 move stably along the guide rod 8.

[0027] The working principle of the connector plastic shell injection mold provided by this utility model is as follows:

[0028] When mold 4 and mold 5 are closed, the protrusion 14 will squeeze the round block 7, causing the round rod 6 to move the connecting plate 21 to the left side of the rectangular groove 23, so that the ejector rod 24 returns to the inside of the rectangular groove 23. Then, the injection molding machine device 13 injects plastic liquid into mold 4 and mold 5 through the injection tube 22. After a period of time, the output end of the cylinder 12 drives mold 5 to move to the right for demolding. As mold 5 moves to the right, the spring 20 will push the round rod 6 to the right through the limiting plate 26, so that the connecting plate 21 drives the ejector rod 24 to move to the right, thereby ejecting the molded product out of mold 4 and then into the collection frame 11.

[0029] Compared with related technologies, the connector plastic housing injection mold provided by this utility model has the following advantages:

[0030] Beneficial effects:

[0031] Through the interaction of components such as protrusion 14, round block 7, round rod 6, connecting plate 21, rectangular groove 23, ejector rod 24, injection molding machine device 13, injection pipe 22, mold one 4, mold two 5, cylinder 12, spring 20 and limiting plate 26, the molded injection product can be automatically demolded without manual demolding, which is efficient and safe.
