In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0023] In one embodiment, such as Figure 1-4 As shown, a demolding structure for an automotive mold with an anti-stick coating includes a base 1, and further includes:

[0024] The upper mold 4 has a lifting plate 5 above the base 1. The lifting plate 5 has a mounting groove 6 on the side close to the base 1. The upper mold 4 and the lower mold 3 are respectively installed in the two mounting grooves 6. The molds slide into the mounting grooves 6 and are fixed with bolts, making the installation and disassembly of the molds more convenient. The bottom of the upper mold 4 has a guide plate 14, and the top of the lower mold 3 has a guide groove 301. The guide plate 14 slides into the guide groove 301, which can dock and position the two sets of molds. Both the upper mold 4 and the lower mold 3 have a molding cavity. The molding cavity is coated with an anti-stick coating to ensure that the molded parts can be demolded smoothly. The top of the upper mold 4 has an injection port 7.

[0025] The top plate 10 has a connecting groove 401 on the top of the upper mold 4, and a groove 501 on the lifting plate 5. A sealing plate 11 is provided inside the groove 501. Multiple sets of top plates 10 are slidably arranged on the sealing plate 11. The top plates 10 pass through the connecting groove 401 and are flush with the inside of the upper mold 4. A connecting plate 9 is provided on the top of the top plate 10. A support frame 19 is provided on the base 1. A sleeve 20 is provided on the support frame 19. A movable frame 8 is slidably arranged on the top of the sleeve 20. The movable frame 8 is elastically installed inside the sleeve 20 by a spring. The movable frame 8 is connected to the connecting plate 9.

[0026] The docking mechanism is located between the upper mold 4 and the lower mold 3, and is capable of docking the upper mold 4 and the lower mold 3.

[0027] The automotive mold demolding structure with anti-stick coating uses an upper mold 4 and a lower mold 3 to injection mold parts. The guide plate 14 slides into the guide groove 301 to facilitate docking and positioning of the two sets of molds. After the part is formed, the lifting plate 5 drives the upper mold 4 to rise. The connecting plate 9 and the top plate 10 below cannot move. The top plate 10 presses the part downward, causing the part to separate from the inner wall of the upper mold 4. After the upper mold 4 rises to a certain height, the connecting plate 9 contacts the lifting plate 5. The lifting plate 5 is lifted by the top plate 10. The part separates from the top plate 10 by its own gravity, thus realizing the demolding of the part. As an example, the left, right, up, and down positions of the various components shown in the attached figure are only one arrangement. The specific positions are set according to specific needs.

[0028] In one embodiment, such as Figure 1-4 As shown, the docking mechanism includes a fixing block 16, a positioning plate 17, and an insert rod 18. The fixing block 16 is provided on the outside of the upper mold 4, and the positioning plate 17 is provided at the bottom of the fixing block 16.

The positioning plate 17 passes through the positioning hole 231. A fixing plate 24 is provided on the lower mold 3, and the insert rod 18 is slidably provided on the outside of the fixing plate 24. A through hole 171 is provided on the positioning plate 17 to cooperate with the insert rod 18. After the upper mold 4 and the lower mold 3 are docked, the positioning plate 17 passes through the positioning hole 231 to position the upper mold 4 and the lower mold 3.

[0029] In one embodiment, such as Figure 4 As shown, a rotating rod 26 is provided inside the fixed plate 24, and a cam 25 is provided outside the rotating rod 26. The rotating rod 26 drives the cam 25 to rotate, and the cam 25 presses the insert rod 18 to both sides, so that the insert rod 18 passes into the through hole 171 and fixes the positioning plate 17, so that the positioning plate 17 cannot be reset upward.

[0030] In one embodiment, such as Figure 4 As shown, one end of the rotating rod 26 extends out of the fixed plate 24 and is provided with a rotating block 27, and both sides of the cam 25 are in contact with the insertion rod 18.

[0031] In one embodiment, such as Figure 1-3 As shown, a guide rail 2 is provided on the base 1, a movable block 12 is provided on the guide rail 2, and a lifting rod 13 is provided on the movable block 12. The top of the lifting plate 13 is rotatably connected to the lifting plate 5. A lead screw 21 is provided inside the guide rail 2. The two ends of the lead screw 21 are provided with external threads with opposite directions of rotation. A transmission belt 22 is provided between the lead screws 21. A motor 15 is provided outside the support frame 19. The motor 15 and the transmission belt 22 drive the lead screw 21 to rotate. The lead screw 21 drives the two movable blocks 12 to move closer or further apart. The movable blocks 12 drive the lifting plate 5 to move up and down through the lifting plate 13.

[0032] The above embodiments of this utility model provide a demolding structure for an automobile mold with an anti-stick coating. The upper mold 4 and the lower mold 3 are installed and fixed. The motor 15 drives the lead screw 21 to rotate. The lead screw 21 drives the lifting plate 5 to descend through the movable block 12 and the lifting plate 13. The lifting plate 5 drives the upper mold 4 to a position that fits with the lower mold 3, so that the guide plate 14 slides into the guide groove 301. The rotating block 27 is turned, and the insertion rod 18 is inserted into the through hole 171 to fix the positioning plate 17.

[0033] After the part is formed, the lifting plate 5 drives the upper mold 4 to rise, and the top plate 10 presses the part downward, causing the part to separate from the inner wall of the upper mold 4. After the upper mold 4 rises to a certain height, the connecting plate 9 contacts the lifting plate 5, and the lifting plate 5 is lifted by the top plate 10. The part separates from the top plate 10 by its own gravity, thus realizing the demolding of the part.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
