[0001] The invention relates to the technical field of injection molds, in particular to a quick positioning injection mold and a use method thereof. Background Art

[0002] An injection mold is a mold for producing plastic products. After the upper and lower molds are closed, the plastic raw material is injected into the mold cavity using an injection device. The plastic raw material is shaped by the mold cavity and finally cooled to obtain the product.

[0003] In the prior art, a Chinese patent with authorization announcement number CN211440926U discloses a diverter plate injection mold for injection molding based on an injection mold, which includes a lower mold, a molding groove is provided on the top of the lower mold, a connecting plate is slidably provided inside the molding groove, and a first plate-shaped cavity is provided inside the connecting plate; a water inlet connecting pipe is provided through one side of the bottom of the connecting plate, and a drainage connecting pipe is provided through the other side of the bottom of the connecting plate; an annular cavity is provided inside the lower mold, and the water inlet connecting pipe and the drainage connecting pipe are both connected to the annular cavity, a water inlet main pipe is provided through one side of the lower mold, and a first drainage main pipe is provided through the other side of the lower mold. The utility model allows the bottom surface of the molding material to be cooled together with its top surface and the surrounding surfaces, thereby preventing the cooling speed of the bottom surface of the product from being slower than the cooling speed of its top surface and the surrounding surfaces, effectively shortening the overall cooling time of the product, and achieving a more ideal actual use effect;

[0004] During the use of the above device, the liquid flowing in the water pipe is used to cool the mold, but the temperature of the mold will also decrease after cooling, which will cause the temperature of the raw material in the injection port (i.e., the channel for injecting the flowing plastic raw material into the mold) to decrease. The raw material with a lowered temperature will affect the flowability, which may easily cause the injection port to be blocked.

[0005] Moreover, in the prior art, a Chinese patent with the authorization announcement number CN214448113U discloses an injection mold, including an upper mold and a lower mold, the upper mold includes an upper mold frame and an upper mold core assembly, the upper mold core assembly includes an upper mold core and a first connecting member, the first connecting member is passed through the upper mold core and connected to the upper mold frame; the lower mold includes a lower mold frame and a lower mold core assembly, the lower mold core assembly includes a lower mold core and a second connecting member, the second connecting member is passed through the lower mold core and connected to the lower mold frame. The connecting member fixes the upper mold core and the lower mold core from the inside, and the upper mold core or the lower mold core can be disassembled and repaired without removing the entire injection mold from the injection molding machine, and during the repair process, the upper mold frame and the lower mold frame can be kept warm continuously. After the repair is completed, the injection mold can quickly restore the production temperature without waiting for the cooled injection mold to heat up as a whole, and the upper mold core and the lower mold core can be quickly disassembled and assembled, which can effectively reduce the man-hours consumed by repairs and improve production efficiency. The utility model also discloses an injection mold system including the above-mentioned injection mold;

[0006] During the use of the above-mentioned device, the upper and lower molds are positioned by the cooperation between the guide pins and the guide pin sleeves when the molds are closed. However, during repeated use, the guide pins and the guide pin sleeves will be worn due to friction. After wear, the gap between the two will increase, thereby affecting the positioning effect between the upper and lower molds, thereby affecting the sealing of the upper and lower molds after the molds are closed. In addition, a certain amount of raw material residues may remain inside the mold after use. If these residues are not cleaned up, it will affect the subsequent product quality.

[0017] Preferably, the liquid inlet hose forms a connecting structure with the heating copper tube fixedly installed inside the heat preservation sleeve, and the high-temperature cooling oil is transported to the inside of the heating copper tube through the liquid inlet hose to heat the injection channel to prevent the plastic raw material from cooling and solidifying.

[0018] Preferably, the heating copper tube forms a connecting structure with the heat exchange box through a liquid outlet hose fixedly installed at the top thereof, and a cooling device for ensuring the final temperature of the cooling oil is fixedly installed at the top of the liquid outlet hose.

The cooling oil inside the heat exchange box is used to exchange heat and cool the liquid in the water-cooling pipe, thereby ensuring the use effect of the water-cooling pipe. After the heat exchange, the cooling oil with increased temperature enters the heating copper tube through the liquid inlet hose. The heating copper tube is used to heat the injection channel and the insulation sleeve is used to keep it warm, so as to avoid the situation where the raw materials inside the injection channel cool down too quickly and condense and block.

[0026] 2. The storage airbag, extrusion cam, take-up wheel and pulling rope are used in coordination. When the upper mold moves downward, the take-up wheel is pulled by the pulling rope to rotate, thereby driving the extrusion cam to rotate under the transmission action between the active bevel gear and the driven bevel gear, so that the extrusion cam squeezes the storage airbag. Finally, the air in the storage airbag enters the interior of the positioning airbag to expand the pressurized airbag, thereby squeezing the positioning rod to keep it in the center of the positioning hole, avoiding positioning deviation and affecting the mold sealing.

[0027] 3. The cleaning nozzle, storage air bag and extrusion device are used in coordination. After the product is taken out of the mold, the upper mold continues to move upward, and the storage air bag is squeezed by the extrusion device, so that the air inside the storage air bag is pressurized and ejected from the cleaning nozzle through the connecting pipe, thereby achieving the purpose of cleaning the residual raw materials in the lower mold.
