A mold is composed of various parts, and different molds are composed of different parts according to the different required products. The core function of a mold is to process the shape of a product by changing the physical state of the molding material. For example, in injection molding, plastic particles melt at high temperature and are then injected into the mold to cool and form; in die casting, metal melts at high temperature and is injected into the mold under pressure to form the required shape. The design and manufacture of molds require highly precise processes and strict quality control to ensure that the products produced meet the design specifications and performance requirements. This tool plays a key role in the manufacturing industry.

[0036] Working principle: When demoulding is required, manually pull the pull rod 6 to move. When the pull rod 6 moves, it will drive the moving plate 8 to move. When the moving plate 8 moves, it will squeeze the compression spring 7. When the moving plate 8 moves to the required position, the spring 18 will push the first clamping block 14 outwards, so as to be clamped and fixed with the first clamping groove 13. When the moving plate 8 moves, it will drive the connecting rod 9 to move. When the connecting rod 9 moves, it will drive the ejector plate 10 to move at the same time. At the same time, press the button 11 to squeeze the first clamping block 14, so that the first clamping block 14 slides into the inside of the moving plate 8. When the first clamping block 14 slides into the inside of the moving plate 8, the compression spring 7 will push the connecting rod 9 and the ejector plate 10 downwards, so as to facilitate the ejection and demoulding of the formed product.

[0037] When closing or separating the mold, manually drive the rotary knob 5 to rotate. When the rotary knob 5 rotates, it will drive the rotary rod 19 to rotate. When the rotary rod 19 rotates, it will drive the gear 20 to rotate at the same time. When the gear 20 rotates, it will drive the first rack plate 21 and the second rack plate 22 to move at the same time. When the first rack plate 21 and the second rack plate 22 move, they will drive the second clamping block 17 to move, so that the second clamping block 17 disengages from the second clamping groove 16. When the second clamping block 17 disengages from the second clamping groove 16, it is convenient to separate the first mold 1 and the second mold 2. On the contrary, it is convenient to connect and fix the first mold 1 and the second mold 2, so as to facilitate mold closing.
