[0023] Embodiment 1:

[0024] like Figure 1-3 As shown, a plastic product manufacturing mold with convenient demoulding includes a lower mold 1, an upper mold 2, an injection groove 3 and an injection tube 17. The upper mold 2 is arranged on the top of the lower mold 1, the injection groove 3 is opened on the surface of the lower mold 1, and the injection tube 17 is arranged on the top of the upper mold 2. A U-shaped frame 4 is arranged at the bottom end of the lower mold 1, and a screw rod 5 is arranged inside the U-shaped frame 4. One end of the screw rod 5 is sleeved with a contact block 6, and a clamping plate 7 is fixedly installed on the front of the contact block 6. A straight tube 8 is arranged inside the clamping plate 7, and a rotating tube 11 is arranged at one end of the straight tube 8. A liquid storage box 9 is arranged at the bottom of the U-shaped frame 4, and a hose 10 is arranged on the front of the liquid storage box 9. A demoulding agent is injected into the liquid storage box 9. After the demoulding agent is solidified on the surface of the injection groove 3, it can accelerate the demoulding speed of the plastic product and improve the demoulding efficiency of the mold. The hose 10 is made of rubber material and has a certain softness. As the contact block 6 moves, the hose 10 will move and deform accordingly, and the spraying tube 12 can spray the demoulding agent normally.

[0025] Embodiment 2:

[0026] Based on the first embodiment, Figure 1 and Figure 4As shown, the length of the rotating tube 11 is greater than the length of the straight tube 8, the opening diameter of the spraying tube 12 is greater than the opening diameter of the rotating tube 11, one end of the hose 10 is fixedly connected with one end of the straight tube 8, a circulating pump 15 is provided on one side of the liquid storage box 9, and a plurality of bases 16 are provided at the bottom of the lower mold 1. The utility model is a plastic product manufacturing mold that is easy to demold. By arranging a screw rod 5, a U-shaped frame 4, a spraying tube 12 and a liquid guide tube 14, the outer surface of the contact block 6 is in contact with the surface of the U-shaped frame 4. As the screw rod 5 rotates, the contact block 6 can move left and right at one end thereof, and the straight tube 8 is limited inside the clamping plate 7.

[0027] Working principle: The mold for plastic products is a tool that is matched with the plastic molding machine in the plastic processing industry and gives the plastic products a complete configuration and precise size. The molten liquid is guided to the inside of the injection molding tank 3 through the injection tube 17. After waiting for a period of time, the plastic product can be injection molded. The manufacturing mold has sufficient hardness, wear resistance and corrosion resistance. Before the processing and production of plastic products, the surface of the injection molding tank 3 can be sprayed with a release agent. At this time, a certain amount of release agent has been injected into the liquid storage tank 9 in advance. Then, start the circulation pump 15, and the staff can rotate the rotating rod 13 clockwise, which will drive the contact block 6 to move to the right at one end of the screw rod 5, and then drive the straight pipe 8 and the hose 10 to move, thereby increasing the range of spraying the release agent. The release agent can reduce the friction between the mold and the product, thereby reducing scratches and damage on the surface of the product. After the release agent is solidified on the surface of the injection molding tank 3 , which can speed up the demoulding speed of plastic products and improve the demoulding efficiency of the mold. The demoulding agent continues to be transported upward along the inner surface of the hose 10, flows into the inside of the straight tube 8 and the rotating tube 11, and then is sprayed onto the surface of the injection groove 3 through the spraying tube 12. The hose 10 is made of rubber material and has a certain degree of softness. As the contact block 6 moves, the hose 10 will move and deform accordingly. The spraying tube 12 can spray the demoulding agent normally. The outer surface of the contact block 6 is in contact with the surface of the U-shaped frame 4. As the screw rod 5 rotates, the contact block 6 can move left and right at one end thereof. The straight tube 8 is limited inside the clamping plate 7. The clamping plate 7 moves synchronously with the movement of the contact block 6, and then it can drive the rotating tube 11 to move. The rotating tube 11 can rotate at one end of the straight tube 8, so that the angle of the spraying tube 12 can be adjusted, and the demoulding agent can be guided from one end of the liquid guide tube 14 to the internal storage of the liquid storage tank 9.
