The movable seats 4 can slide freely on the multiple guide columns 3.

[0028] like Figure 2 , Figure 3 as well as Figure 5 As shown, in this embodiment, two guide grooves 5 are provided on one side of the movable base 4, and the two guide grooves 5 are symmetrically distributed. A slide bar 6 is slidably installed in the guide groove 5. A first mold base 7 is fixedly connected to one side of the slide bar 6. Positioning slots 8 are provided on the surfaces of the two slide bars 6 that are far apart from each other. Two symmetrical mounting slots 9 are provided inside the movable base 4. A slider 10 is slidably installed in the mounting slot 9. A limiting protrusion 11 is fixedly connected to one end of the two sliders 10 that are close to each other, and the limiting protrusion 11 can be embedded in the positioning slot 8. A compression spring 16 is provided inside the mounting slot 9. A movable rod 17 is fixedly connected to block 10. A pull ring 18 is fixedly connected to one end of the movable rod 17 that extends outside the movable seat 4. During the cleaning of the first mold seat 7, the pull ring 18 is used to drive the slider 10 to move in the mounting groove 9 through the movable rod 17, so that the two limiting protrusions 11 are removed from the positioning slot 8, thereby releasing the limiting effect of the limiting protrusions 11 on the slider 6. Then, by using the sliding cooperation between the guide groove 5 and the slider 6, the slider 6 can be pulled out from the guide groove 5, so that the first mold seat 7 can be removed from the movable seat 4 for cleaning.

[0029] like Figure 4As shown, in this embodiment, one of the support plates 2 has two mounting plates 13 installed on one side by connecting bolts 12. A second mold base 14 is fixed between the two mounting plates 13, and the second mold base 14 is fixed to one side of the first mold base 7. During the cleaning of the second mold base 14, by loosening multiple connecting bolts 12, the fixing of the two mounting plates 13 can be released, and the second mold base 14 can be removed for cleaning. This allows the first mold base 7 and the second mold base 14 in the structure to be removed, facilitating the cleaning of the mold with residual material, ensuring the normal operation of subsequent work, and avoiding affecting the quality of the injection molded product.

[0030] It is worth noting that in this embodiment, one end of the compression spring 16 is fixedly connected to the slider 10, and the movable rod 17 passes through the compression spring 16. When the cleaned first mold seat 7 is reassembled on the movable seat 4, the two sliders 6 are inserted into the guide groove 5 by utilizing the sliding cooperation between the guide groove 5 and the slider 6.

During the injection molding process into the mold cavity, by controlling the hydraulic rod 24, one end of the hydraulic rod 24 drives the fixed frame 25 to move together, so that the movable seat 4 moves together with the fixed frame 25. The movable seat 4 pushes the first mold seat 7, so that the first mold seat 7 moves closer to the second mold seat 14, and the first mold seat 7 and the second mold seat 14 are fitted together, so that the two form a mold cavity. Then, through the setting of the feed pipe 15, the molten plastic can be injected into the connected mold cavity through the feed pipe 15.
