For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0026] In one embodiment of the present invention, Figures 1 to 4 As shown, a one-mold multi-cavity mold is provided, including an injection molding component 10, a molding component 20 and a positioning component 30, wherein the injection molding component 10 is respectively installed inside the positioning component 30 and the molding component 20, and the molding component 20 is installed inside the positioning component 30;

[0027] The molding assembly 20 includes a first mold cavity 201 and a second mold cavity 202. The first mold cavity 201 is opened inside the positioning assembly 30, and the second mold cavity 202 is opened inside the positioning assembly 30 and away from one end of the first mold cavity 201. The manifold 103, the drainage pipe 104 and the manifold plate 105 in the injection molding assembly can control the production and molding of the products inside the first mold cavity 201 and the second mold cavity 202, thereby reducing the output of manpower and improving the production accuracy. At the same time, the setting of the ejection assembly 40 facilitates the ejection of the products after the production of the first mold cavity 201 and the second mold cavity 202, thereby solving the problem of easy cracking of the mold and improving the practicality.

[0028] Specifically, by setting the first mold cavity 201 and the second mold cavity 202, multiple products can be produced simultaneously in the same mold, which shortens the production cycle and improves production in the same mold, thereby ensuring consistency of product quality and improving practicality.

[0029] The positioning assembly 30 includes a lower mold base 302, a fixed mold 307 and a movable mold 308. The lower mold base 302 is installed at one end of the fixed mold 307, the fixed mold 307 is installed inside the lower mold base 302, and the movable mold 308 is installed on the upper surface of the fixed mold 307. The first mold cavity 201 is opened inside the movable mold 308, and the second mold cavity 202 is opened inside the fixed mold 307.

[0030] Specifically, through the setting of the fixed mold 307, the shape and size of the fixed mold 307 are fixed, and the mold inside the second mold cavity 202 will also be fixed, thereby improving the quality and consistency of the fixed mold 307 during mass production and improving practicality. Through the setting of the movable mold 308, the movable mold 308 is movable during the production process, and the movable mold 308 can be moved during the opening and closing process of the mold, which is convenient for taking out the finished product and filling the raw materials, thereby realizing the practicality of one mold with multiple cavities.

[0031] The positioning assembly 30 includes an upper mold base 301, a placement plate 305 and a limit plate 306. The upper mold base 301 is installed on the upper surface of the placement plate 305, the placement plate 305 is installed inside the upper mold base 301, the limit plate 306 is installed on the lower surface of the placement plate 305, and the placement plate 305 is located between the upper mold base 301 and the limit plate 306.

[0032] Specifically, when the injection molding component 10 needs to be fixed, the plate 305 can be used to further support the internal components of the injection molding component 10 to avoid deviation and shaking when the product is injected, thereby improving the stability of the injection molding component 10. The limiting plate 306 is provided to further limit the internal components of the injection molding component 10 to avoid deviation of the injection molding component 10 when the product is injected, thereby improving the stability of the injection molding component 10.

[0033] The positioning assembly 30 includes a positioning guide post 303 and a positioning guide sleeve 304 . The positioning guide post 303 is installed inside the placement plate 305 . The positioning guide sleeve 304 is opened inside the movable mold 308 . The positioning guide sleeve 304 is connected to the positioning guide post 303 .

[0034] Specifically, when the injection mold is closed, in order to avoid displacement, the positioning guide column 303 can be used to drive the entire injection mold to be matched and connected with the positioning guide sleeve 304, so that the product after injection molding is consistent with the designed size, and at the same time, the deviation is reduced to within the allowable deviation range, thereby improving the overall stability.

[0035] The injection molding assembly 10 includes an injection port 101 and an injection nozzle 102 . The injection port 101 is disposed inside the upper mold base 301 . The injection nozzle 102 is disposed at one end of the injection port 101 . The injection port 101 is connected to the injection nozzle 102 .

[0036] Specifically, when the injection mold is to be produced, the injection molding raw material must first be transferred to the inside of the injection nozzle 102 through the injection port 101, and then the injection nozzle 102 transfers the injection molding raw material to the inside of the diversion tube 103, so that several diversion tubes 103 can transfer the raw material to the inside of the drainage tube 104 again, and the drainage tube 104 can transfer the raw material to the inside of the diversion plate 105, and then the diversion plate 105 transfers the injection molding raw material to the inside of the molding component 20, thereby realizing the simultaneous production of multiple products in the same mold, shortening the production cycle, and at the same time improving the production in the same mold, ensuring the consistency of product quality, and improving practicality.

[0037] The injection molding assembly 10 includes a diverter pipe 103 , a drainage pipe 104 and a diverter plate 105 . The diverter pipe 103 is opened at one end of the injection nozzle 102 , the drainage pipe 104 is opened at one end of the diverter pipe 103 , and the diverter plate 105 is installed on the lower surface of the limiting plate 306 .

[0038] An ejection assembly 40 is provided inside the diverter plate 105. The ejection assembly 40 includes an ejection plate 401 and an inclined ejector 402. The ejection plate 401 is installed at the bottom of the diverter plate 105, and the inclined ejector 402 is installed inside the diverter plate 105. The inclined ejector 402 is connected to the diverter plate 105. The fixed mold 307 is located between the movable mold 308 and the lower mold base 302.

[0039] Specifically, after the injection molding of the mold is completed, in order to facilitate the removal of the mold after the injection molding is completed, the ejector plate 401 can be moved. When the ejector plate 401 moves, the inclined ejector 402 set inside the diverter plate 105 will be driven to move upward, so as to facilitate the ejection of the product inside the movable mold 308, and facilitate the operator to take out the product after the injection molding is completed, thereby saving a lot of manpower and material resources. At the same time, the problem that the mold cannot be ejected well after the injection molding and the mold is prone to cracking has been solved, thereby improving practicality.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
