Description

Technical Field

[0001] This utility model relates to the field of silicone parts manufacturing technology, specifically to a part-removing mechanism suitable for encapsulating liquid silicone parts in injection molded parts. Background Technology

[0002] Injection molding with liquid silicone coating is a composite manufacturing process. Liquid silicone is coated onto the surface of an injection-molded plastic substrate to form a functional component that combines rigidity and elasticity. During the production of injection-molded liquid silicone coatings, a molding die is typically used to hold the part in place. To improve part removal efficiency during production, a part removal mechanism is needed. However, current part removal mechanisms still have the following shortcomings:

[0003] For example, patent document CN221677935U discloses a part-retrieving mechanism for liquid silicone injection molded parts in plastic packaging. This part-retrieving mechanism for liquid silicone injection molded parts in plastic packaging not only realizes automatic part-retrieving and unloading of liquid silicone injection molded parts in plastic packaging, but also automatically embeds the part to be injected, effectively improving the production efficiency of liquid silicone injection molded parts in plastic packaging. However, since the product and the sprue are not on the same mold side, the embedding and retrieval mechanism needs to be detached from the mold surface and rotated alternately to retrieve the product and the sprue. The embedding and retrieval cycle is too long, increasing production costs and resulting in low production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a part-removing mechanism suitable for injection-molded parts containing liquid silicone parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a part-removing mechanism suitable for encapsulating liquid silicone parts in injection molded parts, comprising a fixing component and a removal component. The fixing component is an integrated structure, and a fixing plate is installed on the lower side of the fixing component. A support frame is installed on the lower side of the fixing plate, and a positioning rod is provided on the front side of the support frame. The removal component is disposed on the surface of the support frame, and the removal component includes a driving cylinder, a gripper body, a support connecting frame, and a fixed suction nozzle. The driving cylinder is disposed at both ends of the front side of the support frame, and a gripper body is provided on the front side of the driving cylinder, with a sprue held inside the gripper body. A support connecting frame is installed on the rear side of the support frame, and the support connecting frame is an integrated structure. A fixed suction nozzle is provided on the rear side of the support connecting frame.

[0006] Furthermore, the supporting connecting frame has a built-in vacuum negative pressure mechanism, and the fixed suction nozzle is connected to the vacuum negative pressure mechanism.

[0007] Furthermore, the fixing plate is an integrated structure, and the rear side of the fixing plate is connected to the front side of the upper end of the support connecting frame.

[0008] Furthermore, the rear side of the drive cylinder is tightly connected to the front side of the support frame, and eight sets of drive cylinders and gripper bodies are correspondingly arranged.

[0009] Furthermore, the upper side of the fixing member is fixed to the frame, and the rear side of the fixing frame is provided with an installation member.

[0010] Furthermore, the front side of the mounting component is provided with an embedding assembly for embedding the plastic part, and the embedding assembly includes a movable hydraulic cylinder, a front support plate, a limiting telescopic rod, and a limiting frame.

[0011] Furthermore, the movable hydraulic cylinder is located on the front side of the upper end of the mounting component, and a front support plate is installed at the front end of the movable hydraulic cylinder.

[0012] Furthermore, a limiting telescopic rod is provided on the rear side of the front support plate, and the rear end of the limiting telescopic rod is connected to the front side of the fixed frame. A limiting frame is provided on the front side of the front support plate.

[0013] This utility model provides a part-retrieving mechanism suitable for encapsulating liquid silicone parts in injection molded parts, which has the following beneficial effects:

[0014] 1. This utility model features a take-out assembly comprising a drive cylinder, gripper body, support frame, and fixed suction nozzle. In use, the lower end of the device is placed between the male and female molds. A positioning rod positions the left side of the drive cylinder on the support frame relative to the mold. The drive cylinder is then activated, causing the gripper body to grasp the sprue in the female mold. Simultaneously, a vacuum negative pressure mechanism drives the fixed suction nozzle to extract liquid silicone product from the male mold. This allows the device to employ a double-sided take-out module, enabling simultaneous removal of the sprue and product without the need for alternating rotation. It offers advantages such as simple and reliable structure, reduced manual insertion and removal time, long service life, increased production efficiency, and improved production capacity.

[0015] 2. This utility model incorporates an embedding component, which includes a movable hydraulic cylinder, a front support plate, a limiting telescopic rod, and a limiting frame. In use, the limiting frame fixes the plastic part, and the lowering device positions the front support plate against the mold core. Activating the movable hydraulic cylinder moves the front support plate forward, which in turn moves the plastic part forward, embedding it into the cavity of the mold core. The extension and retraction of the limiting telescopic rod limits the movement of the front support plate, enabling rapid embedding of the plastic part and further improving production efficiency.
