Description

Technical Field

[0001] This utility model relates to the technical field of powder ring demolding machines, and in particular to a dual-station powder ring demolding machine. Background Technology

[0002] The powder ring demolding machine is a specialized piece of equipment for the automated demolding and separation of powder ring products. It mainly consists of an electric cylinder, a pneumatic cylinder, a pressure sensor, a tray, ejector pins, and a collection box. Its core function is to automatically separate the powder ring from the supporting documents (or carriers): During operation, the documents containing the powder ring are first placed on the tray. The pneumatic cylinder drives the tray to move directly below the electric cylinder. The electric cylinder then moves the ejector pin downwards, inserting it at the junction of the powder ring and the documents, separating the powder ring from the upper and lower layers of the documents. The separated powder ring falls into the collection box below. Subsequently, the ejector pin lifts, and the pneumatic cylinder pushes the tray back to its original position, completing the automatic demolding and collection of the powder ring. It is widely used in production scenarios requiring efficient separation of powder ring products, such as the processing rings for electronic components and precision parts.

[0003] In existing powder ring demolding equipment, some designs use a spring buffer structure at the bottom of the ejector pin and mold plate. While this can prevent damage to some extent, it is significantly inferior to solutions using pressure sensors. The spring buffer structure can only absorb impact force through its own elastic deformation. Its buffering force is fixed and lacks real-time feedback. It cannot dynamically adjust the ejector pin pressure according to the actual bonding strength and separation resistance of the powder ring. When dealing with powder rings of different batches and specifications, improper pressure control can easily lead to powder ring breakage or mold damage. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a dual-station powder ring demolding machine to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a dual-station powder ring demolding machine, including a base frame. A top cover is bolted to the top of the base frame. Two left-right corresponding assembly plates are bolted to the top of the base frame. Two left-right corresponding guide rails are bolted to the top of each assembly plate. A movable seat is slidably connected between the two guide rails.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. During operation, the electric cylinder drives the pressure sensor, which in turn moves the lifting plate and ejector pin downwards. The pressure sensor monitors the pressure changes of the ejector pin on the main body of the powder ring mold in real time. When the pressure exceeds the preset threshold, the control panel receives the signal and controls the electric cylinder to stop.
