Injection molds can produce high-precision, high-strength, lightweight plastic products to meet the requirements of thinness, beauty, durability, etc.
[0003] However, during the injection process of the mold, the epoxy material tends to directly flush the pores in the runner into the bottom of the mold cavity when passing through the runner. The pores are pressed at the bottom of the cavity, making it impossible for the gas to be discharged, resulting in pores formed inside the product, causing a decrease in product quality.

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such here.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.
[0028] During the mold injection process, the epoxy material easily flushes the pores in the flow channel 2 directly into the bottom of the mold cavity 3 when passing through the flow channel 2, resulting in the inability of gas to be discharged, resulting in the formation of dark pores in the product, and the product cannot meet the design requirements. Therefore, the utility model provides the following solution.
[0029] Combination Figure 1 and Figure 2 The utility model provides an injection mold, including: a body 1, and a flow channel 2 and a cavity 3 formed in the body 1; one end of the flow channel 2 is connected to the cavity 3; the other end of the flow channel 2 is used as an open end for injection; the flow channel 2 is horizontally arranged and constructed as a circuitous structure. In this embodiment, the epoxy material enters the flow channel 2 through the open end of the flow channel 2, flows in the circuitous flow channel 2, and then flows into the cavity 3. When the flow channel 2 is constructed as a circuitous structure, the fluidity of the epoxy material during the injection process is effectively improved, for example, the epoxy material can flow evenly; the epoxy material changes its flow direction along with the shape of the flow channel 2 during the flow process, ensuring that the epoxy material smoothly and evenly fills the cavity 3, avoiding the gas from directly rushing into the bottom of the cavity 3, and avoiding the formation of dark pores inside the product, so as to obtain high-quality products and improve the product yield.
[0030] Furthermore, combined with Figure 1 and Figure 2 , the flow channel 2 includes an inflow section 20, an intermediate section 21 and an outflow section 22 which are connected in sequence; the inflow section 20, the intermediate section 21 and the outflow section 22 are arranged on the same horizontal plane. In this embodiment, the lengths of the inflow section 20, the intermediate section 21 and the outflow section 22 can be adjusted in combination with the layout of the cavity 3 in the body 1, and ultimately the formation of dark pores is avoided. The specific arrangement is not further limited here. Furthermore, the flow channel size can also be adjusted according to the filling speed to meet the production efficiency requirements.
[0031] Furthermore, combined with Figure 1 and Figure 2 , the angle between the inflow section 20 and the middle section 21 is set to an acute angle, and the angle between the middle section 21 and the outflow section 22 is set to an acute angle. Further, the angle between the inflow section 20 and the middle section 21 is set to 30° to 60°, and the angle between the middle section 21 and the outflow section 22 is set to 30° to 60°. Through the above-mentioned arrangement, the epoxy material makes a circuitous flow in the flow channel 2 to avoid dead corners, and effectively discharge the gas in the flow channel 2. After entering the cavity 3, the discharged gas can flow out through the exhaust port provided in the cavity 3 to avoid the gas being filled into the bottom of the cavity 3, to avoid the formation of dark pores inside the injection part formed in the cavity 3 and to avoid defects or unevenness on the surface of the product, thereby improving the yield rate. Further, combined with Figure 1 and Figure 2 , the flow channel 2 is constructed in an "N" shape. In this embodiment, in addition to the "N" shape, the shape of the flow channel 2 can also be adjusted according to the properties of the injection material. For example, the flow channel 2 can be constructed in an "S" shape, and the specific structure is not further limited here. By constructing the flow channel 2 in an "N" shape, it is not easy to punch the pores into the bottom of the cavity 3 during the process of making the injection part, causing the gas to be unable to be discharged, thereby avoiding the formation of dark pores inside the injection part.
[0032] Furthermore, combined with Figure 1 and Figure 2 , the inflow section 20 and the outflow section 22 are arranged in parallel.
[0033] Furthermore, combined with Figure 1 and Figure 2 The runner 2 is connected to the injection machine through the inflow section 20, and the runner 2 is connected to the cavity 3 through the outflow section 22. In this embodiment, the epoxy material enters the runner 2 through the open end of the runner 2 from the injection machine, and enters the cavity 3 after flowing through the runner 2, forming an injection part in the cavity 3.
