Description

Technical Field

[0001] This utility model relates to the field of leather bowl forming, and in particular to a cold-resistant leather bowl precision forming device. Background Technology

[0002] Cold-resistant sealing cups, as a key sealing component, are widely used in various low-temperature environments in mechanical equipment. In their production process, precision molding equipment is a core tool for ensuring product quality and production efficiency.

[0003] In existing technologies, during molding, conventional hydraulic equipment is typically used to drive a pressure head downwards, extruding rubber or other cold-resistant materials placed in a mold. During the demolding stage, manual operation is mostly relied upon, with workers using experience and simple tools such as pry bars and clamps to try to separate the molded rubber cup from the mold. Some semi-automated equipment uses a simple ejection device to push the rubber cup out of the mold, but this method lacks precise control.

[0004] However, simple ejector-type demolding devices lack targeted demolding design, often resulting in uneven stress on the leather cup, leading to incomplete demolding or damage during the demolding process. To address this issue, a cold-resistant leather cup precision molding device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cold-resistant leather bowl precision molding device, which aims to solve the problem of difficult demolding in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cold-resistant leather bowl precision forming device, comprising a forming device, a processing table fixedly connected to the forming device, a hydraulic cylinder fixedly connected to the top of the forming device, a forming pressure head fixedly connected to the output end of the hydraulic cylinder, a demolding mechanism provided on the forming device, the demolding mechanism comprising a demolding top plate, the demolding top plate being embedded in the outer wall of the top of the processing table, a fixing plate fixedly connected to the outer wall of the output end of the hydraulic cylinder, a threaded plate slidably connected to the inner wall of the fixing plate, and a hook fixedly connected to the outer wall of the threaded plate.

[0007] As a further description of the above technical solution: the shape of the demolding top plate is H-shaped.

[0008] As a further description of the above technical solution: a motor is fixedly connected to the top outer wall of the fixed plate, and a screw is fixedly connected to the output end of the motor through a coupling. A limit plate is rotatably connected to the end of the screw away from the motor, and the inner wall of the threaded plate is threadedly connected to the outer wall of the screw.

[0009] As a further description of the above technical solution: a limiting rod is fixedly connected to the molding equipment, and the outer wall of the limiting rod is slidably connected to the inner wall of the fixing plate.

[0010] As a further description of the above technical solution: there are two screws, and the two screws are connected by a synchronous belt assembly.

[0011] As a further description of the above technical solution: the number of the limiting plates is three, and the two ends of the other screw are respectively rotatably connected to the outer walls of the other two limiting plates.

[0012] As a further description of the above technical solution: a positioning mechanism is provided on the fixed plate, the positioning mechanism includes a limiting rail, a sliding plate is slidably connected to the outer wall of the limiting rail, a hinge plate is hinged to the top outer wall of the sliding plate, and the outer wall of the hinge plate is fixedly connected to the outer wall of the threaded plate.

[0013] As a further description of the above technical solution: the outer wall of the slide plate near the output end of the hydraulic cylinder is arc-shaped.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the extension rod of the hydraulic cylinder is controlled to retract, which drives the fixed plate and hook to rise. By utilizing the shape of the H-shaped demolding top plate, the molded cold-resistant leather cup can be stably and efficiently removed from the processing table. This avoids the problems of product damage or low demolding efficiency caused by the difficulty of demolding in traditional demolding methods, and effectively improves production efficiency and product quality.

[0016] 2. In this utility model, when the two threaded plates are close together, the arc-shaped outer wall of the slide plate is in contact with the outer wall of the telescopic rod at the output end of the hydraulic cylinder. At this time, the position of the threaded plates can be corrected and positioned, which can prevent the threaded plates from deviating during movement and ensure that the hook can accurately hook the four corners of the demolding top plate. This ensures the accuracy and stability of the demolding mechanism, improves the reliability of the entire equipment operation, and reduces demolding failure or product quality problems caused by component position deviation.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a precision molding device for cold-resistant leather bowls, comprising a molding device 1, a processing table 2 fixedly connected to the molding device 1 for molding the cold-resistant leather bowls, a hydraulic cylinder 3 fixedly connected to the top of the molding device 1, and a molding pressure head 4 fixedly connected to the output end of the hydraulic cylinder 3. The hydraulic cylinder 3 controls the raising and lowering of the molding pressure head 4 through a telescopic rod at the output end, and shapes the cold-resistant leather bowls in the processing table 2 by lowering it. The molding device 1 is provided with a demolding mechanism 5, which includes a demolding top plate 501. The demolding top plate 501 can... To aid in demolding and prevent problems with successful demolding, a demolding top plate 501 is embedded in the outer wall of the top of the processing table 2. The embedded method facilitates limiting and also makes it easy to pull out. A fixing plate 502 is fixedly connected to the outer wall of the output end of the hydraulic cylinder 3. The fixing plate 502 can rise and fall with the rising and falling of the forming head 4. A threaded plate 505 is slidably connected in the inner wall of the fixing plate 502, which plays a sliding limiting role for the threaded plate 505. A hook 506 is fixedly connected to the outer wall of the threaded plate 505. The threaded plate 505 can move, thereby driving the hook 506 to move.

[0026] Reference Figure 2 - Figure 4The demolding top plate 501 is H-shaped. Hooks 506, when positioned apart, can hook onto the four corners of the demolding top plate 501, thus pulling it upwards for easy demolding. A motor 503 is fixedly connected to the top outer wall of the fixing plate 502. The output end of the motor 503 is fixedly connected to a screw 504 via a coupling. The operation of the motor 503 drives the screw 504 to rotate. The end of the screw 504 furthest from the motor 503 is rotatably connected to a limit plate 508, which provides a limiting and load-bearing effect for the screw 504. The inner wall of the threaded plate 505 is threaded onto the outer wall of the screw 504. The rotation of the screw 504 drives the threaded plate 505 to move, and the threaded plate 505 slides within the inner wall of the fixing plate 502, providing a limiting effect and allowing displacement. The screw 504 is a bidirectional threaded rod with two threaded plates 505 symmetrically arranged on the positive and negative threads. 05. Under the rotation of screw 504, the two threaded plates 505 move closer or further apart. A limiting rod 507 is fixedly connected to the molding equipment 1. The limiting rod 507 limits the lifting and lowering of the fixed plate 502. The outer wall of the limiting rod 507 is slidably connected to the inner wall of the fixed plate 502. There are two screws 504. The two screws 504 are connected by a synchronous belt assembly 509. The synchronous belt assembly 509 consists of two sprockets and a chain. The two sprockets are respectively sleeved on the outer walls of the two bidirectional threaded rods. The two sprockets are connected by a chain. When the motor 503 drives one screw 504 to rotate, it can drive the other screw 504 to rotate synchronously through the synchronous belt assembly 509. There are three limiting plates 508. The two ends of another screw 504 are rotatably connected to the outer walls of the other two limiting plates 508. The other two limiting plates 508 provide a limiting and load-bearing effect for the other screw 504.

[0027] Reference Figure 3 - Figure 5 A positioning mechanism 6 is provided on the fixed plate 502. The positioning mechanism 6 includes a limiting rail 601. A sliding plate 602 is slidably connected to the outer wall of the limiting rail 601. The limiting rail 601 limits the sliding plate 602. A hinge plate 603 is hinged to the top outer wall of the sliding plate 602. When the two threaded plates 505 move away from each other, the sliding plate 602 can be moved. The outer wall of the hinge plate 603 is fixedly connected to the outer wall of the threaded plate 505. The outer wall of the sliding plate 602 near the output end of the hydraulic cylinder 3 is arc-shaped. When the two threaded plates 505 are close together, the outer wall of the sliding plate 602 is in contact with the outer wall of the telescopic rod at the output end of the hydraulic cylinder 3 for correction and positioning, preventing the two threaded plates 505 from deviating in position.

[0028] Working Principle: By controlling the start of hydraulic cylinder 3, the telescopic rod at its output end extends, driving the forming head 4 connected to it to descend. At this time, the cold-resistant leather cup raw material placed on processing table 2 is gradually squeezed and shaped under the pressure of forming head 4. After the cold-resistant leather cup is shaped, motor 503 is started, and the screw 504 at the output end of motor 503 begins to rotate. Since screw 504 is a bidirectional threaded rod, and two threaded plates 505 connected by threads on its outer wall are symmetrically distributed on the positive and negative threads, when screw 504 rotates, the two threaded plates 505 will move away from each other along the inner wall of fixed plate 502 under the action of the threads. When the two threaded plates 505 move away from each other to a suitable position, hook 506 can hook the four corners of demolding top plate 501. Since demolding top plate 501 is embedded in the top outer wall of processing table 2, the telescopic rod of hydraulic cylinder 3 is controlled to retract, driving fixed plate 502 and hook 506 to rise. This pulls the demolding top plate 501 upward. Because the demolding top plate 501 is H-shaped, its special shape allows the molded cold-resistant cup to be better removed from the processing table 2 during the pulling process, completing the demolding operation. The limiting rail 601 on the fixed plate 502 limits the sliding plate 602. The hinge plate 603 hinged to the top outer wall of the sliding plate 602 is fixedly connected to the outer wall of the threaded plate 505. When the two threaded plates 505 move away from or close to each other, they will drive the sliding plate 602 to slide on the limiting rail 601. The outer wall of the sliding plate 602 near the output end of the hydraulic cylinder 3 is arc-shaped. When the two threaded plates 505 are close together, the arc-shaped outer wall of the sliding plate 602 is in contact with the outer wall of the telescopic rod at the output end of the hydraulic cylinder 3. This allows for convenient correction and positioning of the threaded plate 505 when not in use, preventing deviations during subsequent movement and ensuring the accuracy and stability of the demolding mechanism 5.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
