Description

Technical Field

[0001] The utility model relates to the technical field of rubber ring processing, in particular to a molding device for processing a crusher rubber dustproof ring. Background Art

[0002] In the production process of rubber dust rings, injection molds are used for molding.

[0003] However, after the existing rubber dust ring is formed, burrs and flash are easily generated at the parting line and are difficult to polish, which makes it difficult for the joint surface of the sealing ring body to fit the inner wall of the valve hole well, and then easily causes oil leakage at the joint between the valve hole and the sealing ring body. Therefore, in order to solve the above-mentioned problems, some technologies have proposed relevant technical structures to assist the use of molding devices. For example, there is a utility model patent with a publication number of CN212717983U, which proposes a sealing ring and a mold for manufacturing a sealing ring. By avoiding the outer parting line and the joint surface, burrs and flash are located at the outer parting line, while the joint surface is relatively smooth and flat, so that the joint surface of the sealing ring body can fit better with the inner wall of the valve hole, thereby reducing the oil leakage at the joint between the valve hole and the sealing ring body.

[0004] From the above disclosed technical content, theoretically speaking, the implementation of the relevant technical structure is conducive to the processing of rubber rings, but the material overflowing from the rubber rings during the processing will stick to the surface of the template, and the material sticking to the surface of the template is not easy to be cleaned. Even when the staff takes out the rubber rings after processing, they will come into contact with sticky materials, and the sticky materials have a certain temperature. When the staff cuts the molded rubber rings, there is a risk of being burned by high temperature, resulting in injuries to the staff. Utility Model Content

[0030] Working principle: When in use, first, after the rubber ring is processed and formed, the retraction of the output shaft inside the hydraulic cylinder 9 is used to drive the separation of the upper module 1 and the lower module 2. At this time, the movement of the guide rod 19 on the inner wall of the support plate 10 plays a guiding role in the vertical movement of the upper module 1. Then, the power supply of the rotating motor 18 is turned on. After the rotating motor 18 is turned on, it drives the rotation of the ball screw 801. Due to the threaded connection between the ball screw 801 and the ball nut 802, the ball screw 801 rotates in a circular manner and drives the vertical lifting movement of the ball nut 802. When the ball nut 802 moves, the extension rod 6 is connected to the inner wall of the fixed rod 5 through the connection of the connecting rod 803. When the extension rod 6 moves upward, it drives the top plate 3 to move inside the lower module 2 through the connection of the moving plate 4. At this time, the rubber ring formed inside the lower module 2 can be ejected, which is convenient for the staff to take the formed rubber ring. Finally, the moving plate 4 also drives the telescopic movement of the round rod 14 inside the sleeve 16, thereby reinforcing the stability of the lifting movement of the top plate 3.
