[0005] The purpose of this invention is to address the aforementioned technical problems by providing a tire molding die that assists in demolding, thus preventing the tire from easily sticking to the die and causing tire damage.
[0006] In view of this, the present invention provides a tire molding mold for assisting demolding, comprising a base, a motor fixedly connected to the inner wall of the base, a fitting block fixedly connected to the output end of the motor, a rotating seat fitted to the top of the fitting block, a lower mold fixedly connected to the top of the rotating seat, a demolding push rod fixedly connected to the inner wall of the base on one side of the motor, a connecting plate fixedly connected to the output end of the demolding push rod, connecting grooves provided at both ends of the connecting plate, a sliding plate movably connected in the grooves of the connecting plate, a telescopic stop fixedly connected to one end of the sliding plate, a rotating ring attached to the outer wall of the telescopic stop, a telescopic support rod slidably connected to the inner wall of the rotating seat fixedly connected to the top of the rotating ring, and an ejector pin fixedly connected to the top of the telescopic support rod;
[0007] A mold closing assembly, located above the base, is used to perform a mold closing operation on the lower mold.
[0008] Based on the above structure, the demolding push rod works by driving the connecting groove to slide vertically through the connecting plate. The sliding of the connecting groove drives the telescopic block to slide horizontally through the sliding plate. This causes the telescopic block to drive the six sets of telescopic support rods to slide vertically through the rotating ring. The sliding of the telescopic support rods drives the ejector pin to lift the formed tire in the lower mold, thereby realizing the demolding operation of the tire and avoiding the tire from sticking to the mold.
[0009] Preferably, the interlocking block is cross-shaped. In this embodiment, by setting the cross-shaped interlocking block, the motor drives the rotating seat to rotate through the interlocking block, which in turn drives the tire material inside the lower mold to rotate. The centrifugal force generated by the rotation of the tire material is used to perform the tire forming operation.
[0010] Preferably, the connecting groove is inclined, and the connection part of the telescopic abutment and the rotating ring is inclined. In this embodiment, it is convenient for the connecting groove to slide horizontally through the sliding plate, so that the telescopic abutment drives the six sets of telescopic support rods to slide vertically through the rotating ring. The sliding of the telescopic support rods drives the ejector pin to lift the formed tire in the lower mold.
[0011] Preferably, the telescopic support rods are provided in six sets, and the six sets of telescopic support rods are distributed in a circle at equal angles about the center of the rotating ring. The center of the rotating ring coincides with the central axis of the lower mold. In this embodiment, the telescopic block drives the six sets of telescopic support rods to slide vertically through the rotating ring. The sliding of the telescopic support rods drives the ejector pin to lift the formed tire in the lower mold, thereby improving the stability of tire demolding.
[0012] Preferably, the mold clamping assembly includes:
[0013] A column is fixedly connected to the side wall of the base. A mold-closing push rod is fixedly connected to the inner wall of the column. A lifting plate is fixedly connected to the output end of the mold-closing push rod. A connecting frame is fixedly connected to the bottom end of the lifting plate. A lifting seat is screwed to the bottom end of the connecting frame. An upper mold is fixedly connected to the bottom end of the lifting seat. An injection port fixedly connected to the outer wall of the connecting frame is screwed to the top end of the upper mold. A limit rod is fixedly connected to the bottom edge of the lifting seat. A limit cylinder fixedly connected to the top end of the rotating seat is sleeved on the outer wall of the limit rod. In this embodiment, the mold-closing push rod drives the lifting plate to slide vertically. The sliding of the lifting plate drives the upper mold at the bottom end of the lifting seat to fit with the lower mold at the top end of the rotating seat through the connecting frame. At the same time, the lifting seat drives the limit rod to slide vertically along the groove of the limit cylinder, improving the accuracy of the lower mold and the upper mold.
[0014] Preferably, the lower mold and the upper mold are located on the same vertical line, and the center of the connecting frame coincides with the center of the upper mold. In this embodiment, the lifting plate slides through the connecting frame to drive the upper mold at the bottom of the lifting seat to fit against the lower mold at the top of the rotating seat.
[0015] Preferably, there are two sets of limiting rods, which are symmetrical about the upper mold. In this embodiment, the lifting seat drives the limiting rods to slide vertically along the groove of the limiting cylinder, thereby improving the accuracy of the lower mold and the upper mold.
[0016] The beneficial effects of this utility model are:
[0017] 1. The tire forming mold for auxiliary demolding is equipped with a limiting rod and a limiting cylinder. The lifting plate slides through the connecting frame to drive the upper mold at the bottom of the lifting seat to fit with the lower mold at the top of the rotating seat. At the same time, the lifting seat drives the limiting rod to slide vertically along the groove of the limiting cylinder, thereby improving the accuracy of the lower mold and the upper mold.
[0018] 2. This tire molding die for assisting demolding uses six sets of telescopic support rods. The demolding push rod works by driving the connecting groove to slide vertically through the connecting plate. The sliding of the connecting groove drives the telescopic block to slide horizontally through the sliding plate. This causes the telescopic block to drive the six sets of telescopic support rods to slide vertically through the rotating ring. The sliding of the telescopic support rods drives the ejector pin to lift the molded tire in the lower mold, thus realizing the demolding operation of the tire. Attached Figure Description

[0028] The mold closing assembly is located above the base 1 and is used to perform the mold closing operation on the lower mold 5.
[0029] Based on the above structure, the demolding push rod 6 works by driving the connecting groove 8 to slide vertically through the connecting plate 7. The sliding of the connecting groove 8 drives the telescopic block 10 to slide horizontally through the sliding plate 9. This causes the telescopic block 10 to drive the six sets of telescopic support rods 12 to slide vertically through the rotating ring 11. The sliding of the telescopic support rods 12 drives the ejector pin 13 to lift the formed tire in the lower mold 5, thereby realizing the demolding operation of the tire.
[0030] In one embodiment, the shape of the interlocking block 3 is cross-shaped.
[0031] In this embodiment, by setting a cross-shaped interlocking block 3, the motor 2 drives the rotating seat 4 to rotate through the interlocking block 3, which in turn drives the tire material inside the lower mold 5 to rotate. The centrifugal force generated by the rotation of the tire material is used to perform the tire forming operation.
[0032] In one embodiment, the connecting groove 8 is inclined, and the connection between the telescopic block 10 and the rotating ring 11 is also inclined.
[0033] In this embodiment, the connecting groove 8 slides through the sliding plate 9 to drive the telescopic block 10 to slide horizontally, so that the telescopic block 10 drives the six sets of telescopic support rods 12 to slide vertically through the rotating ring 11. The telescopic support rods 12 slide to drive the ejector pin 13 to lift the formed tire in the lower mold 5.
[0034] In one embodiment, six sets of telescopic support rods 12 are provided, and the six sets of telescopic support rods 12 are distributed in a circular shape with equal angles about the center of the rotating ring 11, and the center of the rotating ring 11 coincides with the central axis of the lower mold 5.
[0035] In this embodiment, the telescopic block 10 drives six sets of telescopic support rods 12 to slide vertically through the rotating ring 11. The sliding of the telescopic support rods 12 drives the ejector pin 13 to lift the formed tire in the lower mold 5, thereby improving the stability of tire demolding.
[0036] In one embodiment, the mold clamping assembly includes:
[0037] The column 14 is fixedly connected to the side wall of the base 1. The inner wall of the column 14 is fixedly connected to the mold closing push rod 15. The output end of the mold closing push rod 15 is fixedly connected to the lifting plate 16. The bottom end of the lifting plate 16 is fixedly connected to the connecting frame 17. The bottom end of the connecting frame 17 is screwed to the lifting seat 18. The bottom end of the lifting seat 18 is fixedly connected to the upper mold 19. The top end of the upper mold 19 is screwed to the injection port 20 which is fixedly connected to the outer wall of the connecting frame 17. The bottom edge of the lifting seat 18 is fixedly connected to the limiting rod 21. The outer wall of the limiting rod 21 is sleeved with the limiting cylinder 22 which is fixedly connected to the top end of the rotating seat 4.
[0038] In this embodiment, the mold closing push rod 15 drives the lifting plate 16 to slide vertically. The lifting plate 16 slides through the connecting frame 17 to drive the upper mold 19 at the bottom of the lifting seat 18 to fit with the lower mold 5 at the top of the rotating seat 4. At the same time, the lifting seat 18 drives the limiting rod 21 to slide vertically along the groove of the limiting cylinder 22, thereby improving the accuracy of the lower mold 5 and the upper mold 19.
[0039] In one embodiment, the lower mold 5 and the upper mold 19 are located on the same vertical line, and the center of the connecting frame 17 coincides with the center of the upper mold 19.
[0040] In this embodiment, the lifting plate 16 slides through the connecting frame 17 to drive the upper mold 19 at the bottom of the lifting seat 18 to fit against the lower mold 5 at the top of the rotating seat 4.
[0041] In one embodiment, two sets of limiting rods 21 are provided, and the two sets of limiting rods 21 are symmetrical about the upper mold 19.
[0042] In this embodiment, the lifting seat 18 drives the limiting rod 21 to slide vertically along the groove of the limiting cylinder 22, thereby improving the accuracy of the lower mold 5 and the upper mold 19.
[0043] In this embodiment, the tire molding mold for assisted demolding is used in the following way: First, the lower mold 5 and the upper mold 19 are closed. The mold closing push rod 15 drives the lifting plate 16 to slide vertically. The lifting plate 16 slides through the connecting frame 17 to make the upper mold 19 at the bottom of the lifting seat 18 fit with the lower mold 5 at the top of the rotating seat 4. At the same time, the lifting seat 18 drives the limiting rod 21 to slide vertically along the groove of the limiting cylinder 22, thereby improving the accuracy of the lower mold 5 and the upper mold 19.
[0044] Next, the staff injects tire material into the cavity between the lower mold 5 and the upper mold 19 through the injection port 20. Then, the motor 2 drives the rotating seat 4 to rotate through the interlocking block 3, which in turn drives the tire material inside the lower mold 5 and the upper mold 19 to rotate. The centrifugal force generated by the rotation of the tire material is used to form the tire.
[0045] Finally, the mold closing push rod 15 reverses its operation, causing the lower mold 5 and the upper mold 19 to separate. Then, the demolding push rod 6 works to drive the connecting groove 8 to slide vertically through the connecting plate 7. The sliding of the connecting groove 8 drives the telescopic stop block 10 to slide horizontally through the sliding plate 9. This causes the telescopic stop block 10 to drive the six sets of telescopic support rods 12 to slide vertically through the rotating ring 11. The sliding of the telescopic support rods 12 drives the ejector pin 13 to lift the formed tire in the lower mold 5, thus realizing the demolding operation of the tire.
