Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: a refrigerator base injection mold, including a base 1, a fixed mold 11 fixedly installed on the left side of the base 1, an injection port 12 provided on the right side of the base 1, and a track rod 13 fixedly installed on the left side of the base 1, and further including: The convenient mold changing mechanism 2 is installed on the outer wall of the track rod 13. The convenient mold changing mechanism 2 is used to facilitate quick mold switching. Auxiliary mold changing mechanism 3 is installed on convenient mold changing mechanism 2 and is used to assist the user in operating convenient mold changing mechanism 2. The convenient mold changing mechanism 2 includes a translation seat 21, which is slidably connected to the outer wall of the track rod 13. A through groove 22 is provided on the side of the translation seat 21, and a main shaft 23 is rotatably connected to the inner wall of the through groove 22. A flip table 24 is fixedly sleeved on the outer wall of the main shaft 23. A protruding rod 25 is fixedly installed on the outer wall of the translation seat 21, and a moving block 26 is slidably connected to the outer wall of the protruding rod 25. An elastic element 27 is fixedly installed on the outer wall of the moving block 26, and the end of the elastic element 27 away from the moving block 26 is fixedly installed on the outer wall of the translation seat 21. A pin 28 is fixedly connected to the outer wall of the movable block 26. If the moving mold 242 needs to be replaced, the pin 28 is pulled from the movable block 26 to pull the pin 28 out of the inside of the flip table 24, releasing the rotation lock of the flip table 24. Then the entire flip table 24 can be rotated, and the two moving molds 242 can be replaced. After that, the movable block 26 is released, and the pin 28 can be inserted into the inside of the flip table 24 by the restoring force of the elastic element 27, and the position of the moving mold 242 is locked again, thus completing the quick production changeover.

[0017] As one implementation method in this embodiment, such as Figure 2 As shown, pin 28 is slidably connected to the inner wall of translation seat 21, and the end of pin 28 is movably inserted into the inside of flip table 24. In the initial state, pin 28 is inserted into the inside of flip table 24, and flip table 24 cannot rotate, thus locking the position of moving mold 242.

[0018] As one implementation method in this embodiment, such as Figure 3 As shown, a pull rod 29 is rotatably connected to the outer wall of the movable block 26. During production change, the movable block 26 can be pulled from the pull rod 29. After the pin 28 is removed from the inside of the tilting table 24, the pull rod 29 can be rotated to cause the pull rod 29 to abut against the end of the protrusion 25, locking the pin 28 out of the inside of the tilting table 24 for easy operation.

[0019] As one implementation method in this embodiment, such as Figure 2 As shown, limit blocks 241 are welded to both sides of the tilting platform 24, and movable molds 242 are detachably connected to both sides of the tilting platform 24. The movable molds 242 are installed on the side of the tilting platform 24 by means of bolts and can be replaced when damaged. The limit blocks 241 are used to limit the installation position of the movable molds 242.

[0020] As one implementation method in this embodiment, such as Figure 4 As shown, the auxiliary mold changing mechanism 3 includes a connecting block 31, which is rotatably connected to the outer wall of the translation seat 21. The end of the connecting block 31 is fixedly connected to the end of the main shaft 23. A matching groove 32 is provided on the connecting block 31, and a matching rod 33 is movably inserted into the inner cavity of the matching groove 32. When rotating the flip table 24, it can be done from the connecting block 31 on the outside. Through the connection relationship design of the matching groove 32 and the matching rod 33, the user can disassemble and store the matching rod 33 as a whole when idle.

[0021] As one implementation method in this embodiment, such as Figure 4 As shown, an adapter block 34 is fixedly installed at the end of the connecting rod 33, and a round rod 35 is fixedly installed on the outer wall of the adapter block 34. A threaded groove 36 is opened at the end of the round rod 35, and a threaded rod 37 is threadedly connected in the inner cavity of the threaded groove 36. The user can rotate the connecting block 31 from the round rod 35 for easy operation. The threaded rod 37 can rotate and extend inside the threaded groove 36 to further extend the round rod 35.

[0022] As one implementation method in this embodiment, such as Figure 4 As shown, a handle 38 is fixedly installed at the end of the threaded rod 37. A rubber sleeve 39 is fixedly fitted on the outer wall of the handle 38. A rubber ring 391 is fixedly connected to the outer wall of the rubber sleeve 39. A rubber protrusion 392 is fixedly connected to the outer wall of the rubber ring 391. The user can grip the handle 38. The design of the rubber sleeve 39 improves the grip comfort. The rubber ring 391 is used to improve the axial anti-slip performance, and the rubber protrusion 392 is used to improve the circumferential anti-slip performance.

[0023] Working principle: In use, this structure is installed on the injection molding machine. The drive translation seat 21 slides to the right on the track rod 13, which causes the moving mold 242 and the fixed mold 11 to close. Then, injection molding can be performed from the injection port 12. After cooling, the moving mold 242 and the fixed mold 11 are separated to obtain the refrigerator base product. If the moving mold 242 needs to be replaced, the pin 28 is pulled from the moving block 26, causing the pin 28 to be pulled out from the inside of the flip table 24, releasing the rotation lock of the flip table 24. Then, the flip table 24 can be rotated as a whole, thereby replacing the two moving molds 242. Then, the moving block 26 is released, and the pin 28 can be inserted into the inside of the flip table 24 by the restoring force of the elastic element 27, locking the position of the moving mold 242 again, thus completing the quick production changeover.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
