Especially when the upper and lower hot plates move to close the mold and apply pressure, it cannot ensure the same mold closing height, and thus cannot ensure the same thickness of hot molded products. Content of the Utility Model
[0003] Object of the Invention: The object of the utility model is to overcome the deficiencies in the prior art and provide an automatic adjusting mechanism for the equal height of hot molded products that realizes automatic control, ensures the same mold closing height, and thus achieves the same thickness of hot molded products.
[0004] Technical Solution: To solve the above technical problems, an automatic adjusting mechanism for the equal height of hot molded products described in the utility model includes a top plate. A upper hot plate is provided below the top plate, and a lower hot plate is provided below the upper hot plate. Two or four groups of automatic adjusting mechanisms are provided on both sides of the top plate. The automatic adjusting mechanism includes a connecting seat connected to the top plate. An installation seat is provided below the connecting seat. A stepping motor is provided at one end of the installation seat. The stepping motor is connected to a precision lead screw slide table group. The precision lead screw slide table group includes a lead screw and a slide table provided on the lead screw. An equal height step limit block is provided on the slide table. The equal height step limit block is composed of multiple steps with equal heights. A travel guiding group is provided at the other end of the installation seat.
[0005] Further, two groups of the automatic adjusting mechanisms are provided and are respectively arranged in the middle of both sides of the top plate.
[0006] Further, four groups of the automatic adjusting mechanisms are provided and are respectively arranged at the four corners of the top plate.
[0007] Further, the equal height step limit block is provided between the upper hot plate and the lower hot plate.
[0008] Further, the steps on the equal height step limit block gradually increase from one side of the upper hot plate to the outside.
[0009] Further, one end of the lead screw is connected to the travel guiding group.
[0010] Beneficial effects: Compared with the prior art, the remarkable advantages of the present utility model are as follows: The overall structure of the present utility model is reasonably arranged, and it mainly consists of the following components: a stepper motor, a precision lead screw slide table group, an equal-height step limit block, a traveling guide group, an upper hot plate, and a lower hot plate. It is composed of two or four automatic adjustment mechanisms, which are arranged on both sides or four corners of the upper hot plate and the lower hot plate. The equal-height step limit block is made into multiple step sizes with the same height, driven by two or four closed-loop stepper motors, uniformly controlled by a PLC, guided by the precision lead screw slide table group and the traveling guide group, and enters between the upper and lower hot plates simultaneously from both sides of the heating plate. The entry and exit positions of each group are the same, ensuring that the corresponding limit heights are also the same. Therefore, when the upper and lower hot plates move to close the mold and apply pressure, the mold closing height is ensured to be the same, thereby achieving the purpose of the same thickness of the hot-molded products. Since the thickness of each limit block has a corresponding entry and exit distance value of the stepper motor from zero to the corresponding thickness, when in use, only the entry and exit distance value needs to be set to automatically control the required limit thickness of the limit block during mold closing.

Two groups of automatic adjustment mechanisms 4 are provided on both sides of the top plate 1, and they are respectively arranged in the middle of both sides of the top plate 1. The automatic adjustment mechanism 4 includes a connecting seat 5 connected to the top plate 1. An installation seat 6 is provided below the connecting seat 5. A stepping motor 7 is provided at one end of the installation seat 6. The stepping motor 7 is connected to a precision screw slide table group. The precision screw slide table group includes a screw rod 8 and a slide table 9 arranged on the screw rod 8. An equal-height step limit block 10 is provided on the slide table 9.

[0017] The overall structure of the utility model is reasonably arranged and mainly consists of the following components: a stepping motor, a precision screw slide table group, an equal-height step limit block, a traveling guide group, an upper hot plate, and a lower hot plate. It is composed of two or four automatic adjustment mechanisms, which are arranged on both sides or four corners of the upper hot plate and the lower hot plate. The equal-height step limit block is made into multiple step sizes with the same height. Driven by two or four closed-loop stepping motors and uniformly controlled by a PLC, it enters between the upper and lower hot plates from both sides of the heating plate through the precision screw slide table group and the traveling guide group. The entry and exit positions of each group are the same, ensuring that the corresponding limit heights are also the same. Thus, when the upper and lower hot plates move to close the mold and apply pressure, the mold closing height is the same, thereby achieving the purpose of the same thickness of the hot molded product. Since the thickness of each limit block has a corresponding entry and exit distance value of the stepping motor from zero to the corresponding thickness, when in use, only the entry and exit distance value needs to be set to automatically control the required limit thickness of the limit block during mold closing.
