Description

Technical Field

[0001] This utility model belongs to the field of demolding tool technology, specifically relating to a demolding tool suitable for rubber parts with complex shapes. Background Technology

[0002] The demolding tool for complex-shaped rubber parts is a precision demolding device designed specifically for irregularly shaped rubber products. It is mainly used to solve the problem of damage to complex-structured rubber parts caused by traditional demolding methods. Through innovative mechanical structure and buffer system, this tool achieves safe and non-destructive demolding of rubber products with complex features such as curved surfaces and inverted edges.

[0003] Traditional demolding mechanisms mostly use a single drive method, which is difficult to adapt to the demolding requirements of irregularly shaped rubber parts and is prone to product deformation or damage. The buffer system has a simple design and lacks a multi-stage shock absorption structure. The demolding impact force directly affects the mold life. Therefore, a demolding tool suitable for complex-shaped rubber parts is proposed. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example

[0024] Reference Figure 1-4 This is an embodiment of the present invention, which provides a demolding tool suitable for rubber parts with complex shapes, including,

[0025] The base plate 101, the support rod 102 fixedly installed on the surface of the base plate 101, the operation box 103 fixedly connected to the end of the support rod 102, the demolding assembly 104 set at the bottom of the operation box 103, the buffer assembly 105 used in conjunction with the operation box 103, the mold 106 snapped into the inner cavity of the operation box 103, the cover plate 107 snapped into the end of the operation box 103, and the through hole 108 opened on the surface of the cover plate 107.

[0026] The demolding assembly 104 includes a drive component 104a and a mating component 104b that is used in conjunction with the drive component 104a.

[0027] The drive component 104a includes a fixed block 104a-1, a connecting block 104a-2 fixedly connected to the surface of the fixed block 104a-1, a crank 104a-3 rotatably connected to the side surface of the connecting block 104a-2, a handle 104a-4 hinged to the surface of the crank 104a-3, a limiting frame 104a-5 sleeved on the outer surface of the handle 104a-4, and a limiting rod 104a-6 fixedly connected to the side surface of the limiting frame 104a-5.

[0028] The mating component 104b includes a sliding frame 104b-1 fixedly connected to the side wall of the fixed block 104a-1, a sliding column 104b-2 inserted into the end of the limiting rod 104a-6, a rotating rod 104b-3 sleeved on the outer surface of the sliding column 104b-2, and a rotating shaft 104b-4 rotatably connected to the end of the rotating rod 104b-3.

[0029] Specifically, the operator drives the crank 104a-3 to rotate via the handle 104a-4, which in turn moves the limiting frame 104a-5 and the limiting rod 104a-6, causing the slide column 104b-2 to slide along the trajectory of the slide frame 104b-1. The rotating rod 104b-3 converts the linear motion of the slide column 104b-2 into the rotational motion of the rotating shaft 104b-4, forming a multi-angle flexible demolding force. The buffer assembly 105 absorbs the demolding impact through the synergistic effect of the telescopic cylinder 105a-2 and the spring 105a-4. The rubber parts inside the mold 106 achieve non-destructive demolding under the progressive force of the rotating shaft 104b-4, while the through hole 108 of the cover plate 107 ensures smooth venting during the demolding process.

[0030] The buffer assembly 105 includes a buffer component 105a and a load-bearing component 105b used in conjunction with the buffer component 105a.

[0031] The buffer component 105a includes a baffle 105a-1, a telescopic cylinder 105a-2 fixedly connected to the bottom of the baffle 105a-1, a telescopic rod 105a-3 inserted into the center of the telescopic cylinder 105a-2, a spring 105a-4 sleeved on the outer surface of the telescopic rod 105a-3, and a locking block 105a-5 fixedly connected to the bottom of the telescopic rod 105a-3.

[0032] The load-bearing component 105b includes an elastic block 105b-1 that engages with the locking block 105a-5, a locking plate 105b-2 that engages with the end of the elastic block 105b-1, a reinforcing block 105b-3 that is fixedly installed on both sides of the locking plate 105b-2, a rotating rod 105b-4 that is hinged to the side surface of the reinforcing block 105b-3, and a stabilizing block 105b-5 that is rotatably installed at the end of the rotating rod 105b-4.

[0033] It should be noted that when an impact force is generated during the demolding process, the baffle 105a-1 first bears the pressure and pushes the telescopic cylinder 105a-2 to compress. The telescopic rod 105a-3 performs initial shock absorption under the buffering effect of the spring 105a-4. The locking block 105a-5 transmits the remaining impact force to the elastic block 105b-1 for secondary buffering. The locking plate 105b-2 disperses the force through the reinforcing blocks 105b-3 on both sides. At the same time, the rotating rod 105b-4 drives the stabilizing block 105b-5 to adaptively adjust the angle, forming a buffer protection. Through the synergistic effect of the telescopic mechanism and the elastic load-bearing structure, the impact force is absorbed and dispersed step by step, which not only protects the mold 106 from damage, but also ensures the smooth progress of the demolding process, effectively improving the demolding quality of complex-shaped rubber parts and the service life of the mold 106.

[0034] In use, the crank handle 104a-3 drives the limiting mechanism, causing the sliding column 104b-2 to move along a predetermined trajectory. This motion is then converted into a multi-angle rotational demolding force via the rotating rod 104b-3 and the rotating shaft 104b-4, achieving flexible demolding of complex shapes. Simultaneously, the innovatively designed buffer system, through the inclusion of buffer components 105, achieves gradient absorption and dispersion of impact force. This device, through the organic combination of precise mechanical transmission and an intelligent buffer system, ensures both the integrity and accuracy of demolding irregularly shaped rubber parts and effectively protects the lifespan of the mold 106.

[0035] In summary, the drive component transforms manual operation into precise multi-angle demolding force, ensuring complete demolding of irregularly shaped rubber parts; the buffer component 105 effectively absorbs demolding impact, significantly extending the service life of the mold 106; the modular design and ventilation structure make operation more convenient and efficient. This device solves the problem of poor adaptability of traditional tools to complex shapes, improving demolding quality and production efficiency.
