DETAILED DESCRIPTION

[0024] See also Figures 1-4 ,

[0025] Embodiment 1: A refrigerator drawer mounting hole processing mold, comprising a mounting plate 1, a lower mold 2 is arranged on the top of the mounting plate 1, an injection mold groove 3 is opened in the middle of the top of the lower mold 2, an injection mold groove 3 is opened on the side wall of the injection mold groove 3, and a glue injection head 5 is arranged at the end of the injection mold channel 4, limiting screws 6 are evenly arranged around the top of the lower mold 2, and fastening nuts 7 are arranged on the limiting screws 6, and a quick demolding component 8 is arranged on the top of the lower mold 2.

[0026] The quick demolding assembly 8 includes an upper mold 801 arranged on the top of the lower mold 2. A mold groove abutting block 802 is arranged at the bottom of the upper mold 801. A top moving groove 803 is opened at the top end of the upper mold 801. A bottom connecting groove 804 is opened at the bottom of the mold groove abutting block 802. A closing connecting plate 805 is arranged in the bottom connecting groove 804. Two abutting insertion holes 806 are symmetrically opened on the inner wall of the bottom connecting groove 804. A demolding push rod 807 is inserted into the abutting insertion hole 806.

[0027] The bottom end of the demolding push rod 807 is rotatably connected to the top surface of the closing connecting plate 805. The top end of the demolding push rod 807 penetrates through the upper mold 801 and extends into the top moving groove 803. A push rod connecting plate 808 is arranged at the top end of the demolding push rod 807. Two limiting insertion slots 809 are symmetrically opened on both sides of the inner wall of the top moving groove 803. The end of the push rod connecting plate 808 extends into the limiting insertion slot 809. A top connecting frame 810 is arranged at the top end of the upper mold 801. A pushing screw rod 811 is threadedly inserted in the middle of the top connecting frame 810.

[0028] The bottom end of the pushing screw rod 811 is rotatably connected to the middle of the top end of the push rod connecting plate 808. Fixing screw rods 812 are arranged around the top end of the mold groove abutting block 802. The top ends of the fixing screw rods 812 all penetrate through the upper mold 801 and extend into the top moving groove 803. Fixing nuts 813 are sleeved on the top ends of the fixing screw rods 812. Limiting through holes 814 are evenly opened around the upper mold 801. The top ends of the limiting screw rods 6 all penetrate through the limiting through holes 814.

[0029] Embodiment Two: The difference between this embodiment and Embodiment One is that, among them, the thickness of the closing connecting plate 805 is the same as the depth of the bottom connecting groove 804.

[0030] So that the closing connecting plate 805 is inserted inside the bottom connecting groove 804 and can be flush with the bottom horizontal surface of the mold groove abutting block 802.

[0031] Embodiment Three: The difference between this embodiment and Embodiment One is that, among them, both ends of the top connecting frame 810 extend to the side edges of the top of the top moving groove 803 and are connected to the upper mold 801 through the arranged connecting blocks.

[0032] So that the top connecting frame 810 is fixed at the top end of the upper mold 801 and will not block the disassembly of the fixing nut 813 at the top of the fixing screw rod 812.

[0033] Embodiment Four: The difference between this embodiment and Embodiment One is that, among them, a handle facilitating rotation is arranged at the top end of the pushing screw rod 811.

[0034] So that it is more convenient for the user to rotate the pushing screw rod 811.

[0035] In this embodiment, during the actual production of the existing processing die for the refrigerator drawer installation holes, due to the irregular shape of the die for the drawer installation holes, it is difficult to quickly remove the die during the demolding process. If forced to pull, irreversible damage will be caused to the die, which is not convenient for the user to demold and use.

[0036] In summary, during the specific implementation, when the user injects liquid into the internal injection mold cavity 3 through the injection head 5 and the injection runner 4, and after molding by the cooperation of the mold cavity abutting block 802 and the injection mold cavity 3, when the molded product adheres to the outside of the mold cavity abutting block 802, the user can remove the fastening nut 7 at the top of the limit screw 6 and take out the quick demolding assembly 8 from above the lower mold 2.

[0037] Next, the user can rotate the push screw 811. Since the push screw 811 is threadedly inserted in the middle of the top connecting frame 810, the push screw 811 can move downward. And the two ends of the push rod connecting plate 808 extend into the limit slot 809. Therefore, the push rod connecting plate 808 will only be pushed downward by the push screw 811. The bottom end of the push rod connecting plate 808 is connected with two demolding push rods 807.

[0038] The bottom end of the demolding push rod 807 passes through the abutting jack 806 and is connected with the closing connecting plate 805. Thus, the closing connecting plate 805 can be pushed downward below the mold cavity abutting block 802, so as to push the molded product adhering to the surface of the mold cavity abutting block 802 and separate the product from the surface of the mold cavity abutting block 802.

[0039] And because the mold cavity abutting block 802 and the upper mold 801 are inserted on the upper mold 801 through the set fixing screw 812, it is more convenient for the user to remove the mold cavity abutting block 802 from the upper mold 801, which is convenient for the user to repair and maintain the mold cavity abutting block 802.
