[0013] 1. This utility model provides a stamping die base, which includes an upper die base, a back release plate, and a lower die base arranged sequentially from top to bottom. Two sets of connecting components are provided between the upper die base and the lower die base. The overall structure is simple and reasonably designed. The connecting components include a lower fixed base and an upper fixed base disposed on the lower fixed base. A nylon rope is provided between the lower fixed base and the upper fixed base. The lower fixed base includes a lower body, which is a hollow cavity structure with an opening at one end. A return spring and an inner sliding plate connected to the return spring are provided in the cavity of the lower body. Multiple unlocking limit blocks are fixed on the upper end face of the inner sliding plate. The upper fixed base includes an upper body, which is a hollow cavity structure with openings at both ends. The device contains a slide block with multiple positioning pins fixed around its circumference. These pins pass through the upper body from top to bottom and connect to multiple unlocking limit blocks. A nylon rope connects to the inner slide plate and the slide block at both ends. During operation, the operator holds the handle and lifts the slide block upwards, causing the nylon rope to pull the inner slide plate and the unlocking limit blocks upwards. This pushes the positioning pins upwards, separating them from the lower fixed seat. This allows the upper mold base to separate from the back release plate or vice versa, completing the unlocking process. The entire unlocking process can be completed simply by the operator using the handle, eliminating the hassle of disassembly with tools. The disassembly process is quick and convenient, making maintenance easier and more practical.

At this time, the top of the positioning post 425 is located within the upper seat 421, and its bottom is located within the lower seat 411, so that the lower fixed seat 41 and the... The upper fixed seat 42 cannot be separated. At this time, the upper mold seat 1 and the back release plate 2 or the back release plate 2 and the lower mold seat 3 are fixed together. They can only be separated when the positioning pin 425 is completely retracted into the upper seat body 421. Multiple positioning pins 425 are respectively set in multiple shallow side grooves 4212, and multiple positioning pins 425 can move in the vertical direction. Multiple shallow side grooves 4212 are each provided with deep side grooves 4213. Multiple positioning pins 425 pass through multiple shallow side grooves 4212 and contact the inner wall of multiple deep side grooves 4213, so that the positioning pins 425 can only move in the vertical direction and will not shake.

[0028] Working principle: Please refer to the following again. Figures 1 to 4 In the operation of this utility model, taking the multiple sets of connecting components 4 arranged between the upper mold base 1 and the back release plate 2 as an example: multiple positioning pins 425 pass through the upper body 421 in the vertical direction and are in contact with multiple magnets 4143, so that the positioning pins 425 and the unlocking limit block 414 become one unit. Since the lower body 411 is fixed on the back release plate 2 and the upper body 421 is fixed on the upper mold base 1, the upper mold base 1 and the back release plate 2 are kept connected. When it is necessary to disassemble and maintain the upper mold base 1 and the back release plate 2... When the operator holds the operating handle 424 and lifts it upward, the slide block 422 will move multiple positioning pins 425 upward, causing the multiple positioning pins 425 to separate from the multiple magnets 4143. Then, they will retract into multiple deep side grooves 4213, while the multiple unlocking limit blocks 414 will always be located inside the lower seat body 411. At this time, there is no connection between the lower seat body 411 and the upper seat body 421, so that the upper mold base 1 and the back release plate 2 can be separated, which facilitates maintenance work and realizes tool-free disassembly and assembly.
