[0034] Injection unit, connected to the hot runner plate 2; the injection unit penetrates through the upper template 11, the hot runner plate 2, the connecting plate 31 and the front mold 41, and is communicated with the injection cavity 43, and the injection unit is used to inject the plastic melt into the injection cavity 43 for molding;

[0035] Lower template 12, arranged at the lower end of the bottom plate 32.

[0036] Optionally, in this embodiment, the quickly replaceable and diversified injection mold includes an upper template 11, a hot runner plate 2, a connecting plate 31, a front mold 41, a rear mold 42, an injection unit, and a lower template 12. The hot runner plate 2 is disposed at the lower end of the upper template 11, and the hot runner plate 2 can accurately control the temperature of the plastic melt in the runner, that is, ensure the temperature of the plastic melt in the injection unit, and ensure the fluidity and injection performance of the plastic. The connecting plate 31 is disposed at the lower end of the hot runner plate. A bottom plate 32 is provided at the lower end of the connecting plate 31. An accommodating cavity is formed by enclosing between the connecting plate 31 and the bottom plate 32, and the accommodating cavity is used for placing the front mold 41 and the rear mold 42. The front mold 41 is disposed in the accommodating cavity, the rear mold 42 is disposed at the lower end of the front mold 41, and an injection cavity 43 is formed by enclosing between the rear mold 42 and the front mold 41. The injection cavity 43 is used for injection molding of products. An insert groove 13 is formed on the upper template 11, and the insert groove 13 sequentially penetrates through the upper template 11, the hot runner plate 2, the connecting plate 31, and the front mold 41. The lower end of the insert groove 13 is also connected to the rear mold 42. Since there are multiple product models, for example, the product has round holes, square holes, oval holes, or no holes. During the product manufacturing process, different types of products need to be manufactured by replacing different molds, that is, replacing the injection inserts placed in the injection cavity 43. Removing the upper template 11, the hot runner plate 2, the connecting plate 31, and the front mold 41 in sequence requires a large amount of time and labor, and the time cost and labor cost are relatively high. Through the setting of the insert groove 13, since the insert groove 13 penetrates through the upper template 11, the hot runner plate 2, the connecting plate 31, and the front mold 41 and is connected to the rear mold 42, that is, when the injection insert needs to be replaced, a hex key can be inserted into the insert groove 13 to sequentially remove the injection inserts in the front mold 41 and the rear mold 42, and then the replaced injection inserts are placed into the front mold 41 and the rear mold 42, and then product injection is carried out, saving the time for disassembling the mold, reducing the labor cost, and improving the production efficiency of the product. The injection unit is connected to the hot runner plate 2. The injection unit penetrates through the upper template 11, the hot runner plate 2, the connecting plate 31, and the front mold 41 and communicates with the injection cavity 43. The injection unit is used to inject the heated plastic melt into the injection cavity 43 to form a product. The lower template 12 is disposed at the lower end of the bottom plate 32. Through the setting of the above components, the mold replacement time when injecting different models of products is reduced, and the production efficiency of the product is improved.

[0037] In this embodiment, the injection unit includes a plunger 51, a barrel 52, and a nozzle 53. The plunger 51 movably penetrates through the upper template 11. The barrel 52 is used to store and heat the plastic melt. After the heating is completed, the plastic melt moves downward through the movement of the plunger 51. When passing through the hot runner plate 2, the hot runner plate 2 is used to control and adjust the temperature of the plastic melt. The plastic melt flows into the injection cavity 43 through the nozzle 53 and is cooled and formed to complete the injection of the product.

[0038] In this embodiment, the quickly replaceable and diversified injection mold further includes an ejector plate 61 and an ejector base plate 62. The ejector plate 61 is disposed at the lower end of the bottom plate 32, and the ejector plate 61 is connected to the ejector pins. The ejector base plate 62 is disposed at the lower end of the ejector plate 61. After the product is injection molded and the front mold 41 and the rear mold 42 are opened, the ejector plate 61 drives the ejector pins to move upward to eject the product. The ejector base plate 62 provides stable support and positioning for the ejector pins to ensure that the ejector pins can work accurately and reliably during the demolding process. Further, in this embodiment, a spacer block 7 is further disposed between the bottom plate 32 and the lower template 12. The spacer block 7 can fix the upper template 11 and the lower template 12 and bear the pressure of the mold during operation to prevent the mold from deforming or being damaged during the injection molding process.

[0039] In this embodiment, a heat insulation plate 8 is further disposed at the upper end of the upper template 11, and the heat insulation plate 8 is detachably disposed at the upper end of the insert groove 13. The heat insulation plate 8 is used to isolate the heat generated during the injection molding process of the mold to prevent scalding the surrounding staff. And the heat insulation plate 8 is detachably disposed at the upper end of the insert groove 13. When it is necessary to replace the injection insert, the heat insulation plate 8 is opened, and the injection insert is replaced with a hex key. And through the setting of the heat insulation plate 8, it is prevented that foreign impurities enter the injection cavity 43 through the insert groove 13, affecting the injection molding quality of the product.

[0040] In this embodiment, mounting holes are provided on both the upper template 11 and the hot runner plate 2, and the upper template 11 and the hot runner plate 2 are fixedly connected by bolts, which is convenient for subsequent disassembly, replacement or maintenance.

[0041] The above embodiments only represent the implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
