Problems solved by technology
[0004] Therefore, the technical problem to be solved by the present invention is to solve the problem that the liquid injection outlet of the existing injection mold is generally above the ejector plate. It must be in a horizontal state, and may directly flow through the ejector plate, resulting in the problem of liquid leakage; for this reason, the present invention provides an injection mold, including: injection molding cavity; ejector plate, used to inject molded parts Ejecting the injection mold; the guide cavity, which runs through the ejector plate; the guide member, which is arranged in the guide cavity, which is close to the side of the injection molding cavity; the guide member and the ejector plate There is an injection gap between them; the guide has a guide channel for the injection molding solution to enter the injection cavity, and the liquid outlet pipe of the injection molding machine enters the guide cavity to pass through the ejector plate and the guide flow channel connected

Embodiment 1
[0031] This embodiment provides a kind of injection mold, such as figure 1 , figure 2 As shown, it includes: an injection molding cavity 17; an ejector plate 2, which is used to eject the injection molded parts out of the injection mold; a guide cavity 3, which runs through the ejector plate 2; a guide member 5, which is arranged on the guide In the flow cavity 3, it is close to the side of the injection molding cavity 17; there is an injection gap between the flow guide 5 and the ejector pin plate 2; The diversion channel 9 of the cavity 17, the liquid outlet pipe of the injection molding machine enters the diversion cavity 3 to pass through the thimble plate 2 and communicate with the diversion channel 9; in this solution, the diversion cavity body 3, through the ejector plate 2; then the liquid outlet pipe of the injection molding machine is passed into the guide cavity 3 to communicate with the guide channel 9 of the guide member 5, and the guide channel 9 is connected w...

An injection mold comprises an injection molding cavity, an ejector pin plate, a flow guide cavity and a flow guide part, wherein the ejector pin plate is used for ejecting an injection molded part from the injection mold; the flow guide cavity penetrates through the ejector pin plate; the flow guide part is arranged in the flow guide cavity and is close to one side of the injection molding cavity; there is an injection molding gap between the flow guide part and the ejector pin plate; and the flow guide part has a flow guide channel used for injection molding solutions to enter the injectionmolding cavity, and an injection molding machine outlet pipe enters the flow guide cavity so as to penetrate through the ejector pin plate to communicate with the flow guide channel. The injection mode aims to solve the problem that a liquid injection outlet of an existing injection mold is usually above an ejector pin plate, when an injection molding machine injects liquid into a liquid injectioninlet of a sprue bush, the liquid injection inlet is not in a horizontal state during liquid injection, the liquid possibly flows into the ejector pin plate directly, and as a result, a liquid leakage phenomena is caused.
Description
technical field [0001] The invention relates to the field of injection molds, in particular to an injection mold. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for endowing plastic products with complete structure and precise size. The plastic material melted by heat is injected into the mold from the nozzle under high pressure, and after cooling, the molded product is obtained. [0003] The sprue sleeve is the flow channel for injecting the molten plastic material from the nozzle of the injection molding machine into the mold. It is a metal fitting connecting the molding mold and the injection molding machine. In the prior art, the injection outlet of the sprue sleeve is generally on the ejector plate. When the injection molding machine injects liquid into the liquid injection inlet of the sprue sleeve, the plastic liquid will enter the injection cavity through the flow channel in the ejector plate, but when the...
