Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to an injection mold with a multi-layer flow diversion structure. Background Art

[0002] Injection mold Injection molding, as one of the important molding methods in plastic processing, is widely used in various fields of industrial production. With the increasing application of plastic products, people have higher and higher requirements for the precision, surface quality and strength of plastic products. Injection mold is a tool for producing plastic products; it is also a tool that gives plastic products a complete structure and precise size.

[0003] Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and melted plastic into the membrane cavity by the injection molding machine, and the molded product is obtained after cooling and solidification. The injection mold is an important process equipment for the production of various industrial products. With the rapid development of the plastics industry, various CNC machining processes are used in the processing of injection molds. The most widely used are CNC milling and machining centers. CNC wire cutting and CNC EDM are also widely used in CNC mold machining.

[0004] Wire cutting is mainly used in the processing of various straight-wall molds, such as concave and convex molds in stamping processing, inserts and sliders in injection molds, electrodes for electrospark machining, etc. For mold parts with very high hardness, as well as mold cavities or cores of rotating bodies, such as injection molds for bottles and basins, and forging molds for shafts and discs, the application of CNC drilling machines in mold processing can also help improve processing accuracy and shorten processing cycles.

[0005] In order to improve production efficiency, the injection mold in the prior art is provided with multiple injection molding cavities in some injection molds, wherein the multiple injection molding cavities are connected to the injection channel through a diversion device. When the injection liquid flows in the diversion device, due to heat loss, part of the injection liquid solidifies inside the diversion device. In order to solve the above technical problems, relevant patents have been proposed in the prior art, such as a Chinese patent with application number 202322840359.7, authorization announcement number CN221161330U, and name "A injection liquid diversion structure for a lightweight automobile injection mold". The above patent discloses an injection liquid diversion structure for a lightweight automobile injection mold, including a bottom plate, a mold assembly is provided on the top of the bottom plate through a pair of support plates, the mold assembly includes an upper mold and a lower mold matched with the upper mold, and the lower mold is arranged on the top of the support plate; a plurality of molding cavities are provided in the lower mold, and an injection main pipe for injection of injection liquid is provided in the upper mold, and a plurality of diversion pipes are connected to the bottom of the injection main pipe through a diversion valve, and a diversion duct docking with the molding cavity is provided in the diversion pipe.

[0006] The injection liquid diversion structure in the above patent is to inject the injection liquid from the injection port of the injection main pipe, and then the injection liquid injected into the injection main pipe is diverted through the diverter valve to the diverter conduit in the diverter pipe, and finally the injection liquid flows from the diverter conduit to the molding cavity. Injection molds such as the above patents can meet work needs to a certain extent. It is known that when the mold is performing injection molding, the injection liquid will enter the mold cavity through the injection port through the diverter channel. Before entering the mold cavity, the diverter channel needs to be filled first, and then the injection liquid from the outside enters the diverter channel. Under the action of pressure, the injection liquid in the diverter channel will be squeezed into the mold cavity for injection molding.

[0007] However, after the injection molding operation of the mold is completed, there will be no more injection molding liquid from the outside world entering the shunt channel. After the injection molding liquid is cooled and formed, the shunt channel will be blocked. For this reason, in the prior art, after the injection molding operation is completed, water is usually used to rinse the inside of the shunt channel, which can make the inside of the shunt channel unobstructed to a certain extent. However, when the injection molding liquid after cooling and forming is bonded to the inner wall of the shunt channel, water cannot rinse the impurities on the inner wall of the shunt channel clean. When the injection molding operation is performed next time, the injection molding liquid with a relatively large pressure will mix the impurities on the inner wall of the shunt channel together and enter the mold cavity for injection molding operation, which will affect the quality of the injection molded product. At the same time, in a batch of products that have just been injected, it is not certain which part is mixed with impurities. In order to improve the overall yield rate of the product, the product needs to be deeply tested, which will lead to an increase in the cost of production, and there are certain shortcomings.
