Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an ejection structure for a thermoforming mold for automotive parts. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the processing of automotive parts; thermoforming is the process of heating thermoplastic sheets to a softening temperature, making them in a highly elastic and plastic state, and then applying pressure (such as vacuuming, compressed air or mechanical pressure) to make the sheet fit into the mold cavity, and after cooling, it is shaped into a product.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Thermoforming Mold for Automotive Parts," patent application number: 201921278426.8. Both the punch and die have internal cooling channels. The fixing plate is movably connected to an electromagnetic slide rail via an electromagnetic slider. A first clamping plate and a second clamping plate are provided on the side of the fixing plate near the die. A cylinder is installed at the top of the fixing plate, and a fan is installed on the side of the fixing plate near the die. This invention, through the cooperation of the cylinder, the first clamping plate, and the second clamping plate, clamps the sheet material, improving the mold closing process. The device offers enhanced safety features during processing and can clamp sheets of varying thicknesses, improving its applicability. The movement of the fixed plate, driven by an electromagnetic slide rail, replaces manual feeding and unloading, reducing the workload. Cooling of the mold, facilitated by a fan and cooling channels, shortens cooling time and improves work efficiency. However, after processing, the thermoforming mold makes material removal inconvenient due to the thermoplastic material adhering tightly to the mold, requiring a lengthy and slow clamping process. This reduces the efficiency of subsequent processing and impacts the overall processing progress.

[0004] Therefore, it is necessary to design and modify the thermoforming mold to effectively prevent its slow material handling efficiency. Utility Model Content
