[0030] Reference Figure 1 , a front cover 100 is proposed, which is a rectangular groove structure. The four side walls of the front cover 100 are respectively provided with two buckle groups 110, and the buckle groups 110 include two adjacent side plates 111. The side plates 111 are provided with through holes 112 for passing the lock rod for fixing. In the related art, the front cover 100 is manufactured by injection molding, but the buckle groups 110 need to be processed again after molding, which requires additional labor costs and has low production efficiency.

[0031] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, which is a front cover injection mold proposed by the utility model, includes a base 200, a pillar 300, a rear template 400, a front template 500, a runner template 600 and a top template 700 arranged in sequence from bottom to top, and two pillars 300 are provided, which are arranged on both sides of the top surface of the base 200 for supporting the rear template 400, the top template 700 is provided with a glue injection nozzle 710, and the runner template 600 is provided with a glue injection channel, and the glue injection channel is connected to the glue injection nozzle 710. The front template 500 is provided with an upper mold core, and the rear template 400 is provided with a lower mold core 410 and four side cores 420. The four side cores 420 are arranged vertically in pairs in a rectangular shape around the lower mold core 410. The upper mold core cover is provided on the lower mold core 410, and cooperates with the side core 420 and the lower mold core 410 to form a cavity. The side of the side core 420 facing the lower mold core 410 is a molding surface, and the molding surface is provided with two molding convex edges 421. Adjacent positions on both sides of the molding convex edges 421 are provided with penetrating sockets 422. The sockets 422 are plugged with molding plates 430. The molding plates 430 extend out of the sockets 422 and form molding grooves 423 with the convex edges for molding the side plates 111. The molding plates 430 are provided with bosses 431. The bosses 431 are located in the molding grooves 423, and the ends of the bosses 431 abut against the side walls of the convex edges to form the through holes 112. It is understandable that the lower mold core 410, the upper mold core and the four side mold cores 420 cooperate to form a mold cavity, wherein the lower mold core 410 and the upper mold core mainly cooperate to form the main part of the front cover 100, including its groove structure and the mesh bottom plate, and the side mold cores 420 respectively correspond to the side walls with the buckle group 110. It should be noted that the side mold core 420 is formed by the molding plate 430 and the molding convex edge 421 to form a molding groove 423 to correspond to the shape structure of the side plate 111, and the molding plate 430 is provided with a convex column 431, and the end of the convex column 431 abuts against the side wall of the molding convex edge 421 to form the corresponding through hole 112 on the side plate 111. The four side mold cores 420 are all of similar structure, so as to realize the single injection molding of the front cover 100 without additional processing, reduce labor costs, and improve production efficiency. It is easy to understand that the top template 700 is provided with a glue injection nozzle, the flow channel template 600 is provided with a glue injection channel, and the base 200, the support 300, etc. are conventional settings in the field and are not elaborated here.

[0032] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6, the part of the molding plate 430 extending out of the socket 422 is the molding part 432, and the protrusion 431 is located on the side wall of the molding part 432. Furthermore, positioning steps 423 are provided between the two sockets 422 on both sides of the molding convex edge 421, and the inner side wall of the molding part 432 abuts against the positioning steps 423 to limit the molding plate 430 from extending into the socket 422. It can be understood that the molding plate 430 and the side core 420 are split structures. When it is needed, the molding plate 430 is inserted from the molding surface to the other side away from the molding part 432 toward the socket 422 until the molding part 432 abuts against the positioning steps 423 to complete the installation, and the displacement of the molding plate 430 is limited to ensure that the molding groove 423 is not deformed, so as to ensure the molding effect of the buckle assembly 110.

[0033] Reference Figure 6 Furthermore, in some embodiments, a positioning notch 433 is provided at the bottom of the molding plate 430, and a positioning boss is provided at the side core 420. The positioning notch 433 can be snapped into the positioning boss to position the length of the molding plate 430 extending out of the socket 422. That is, during installation, when the positioning notch 433 is snapped into the positioning boss, it is convenient for workers to quickly determine the installation position of the molding plate 430 and the distance of the insertion into the socket 422, and the positioning notch 433 can also play a certain limiting role to prevent the molding plate 430 from falling off.

[0034] Reference Figure 4 The side wall of the lower mold core 410 close to the side mold core 420 is provided with a clearance notch, and the position of the clearance notch corresponds to the position of the plug 422 of the side mold core 420. Further, the lower mold core 410 is provided with a molding convex plate 411, and the molding convex plate 411 cooperates with the molding groove 423 to cooperate with the molding buckle group 110. To ensure the airtightness of the entire cavity, prevent the need for trimming and cleaning after molding due to glue leakage, and ensure the product processing effect.

[0035] Reference Figure 3 In some embodiments, the side core 420 is connected to a slider, which is slidably connected to the rear template 400. The slider is provided with a guide groove, and the front template 500 is provided with a guide column. When the front template 500 is placed against the rear template 400, the guide column is inserted into the guide groove. When the front template 500 moves away from the rear template 400, the guide column disengages from the guide groove and drives the slider to move away from the lower mold core 410, so as to quickly separate the molding groove 423 and the formed buckle group 110 to prevent product damage during demolding.

[0036] Reference Figure 3In other embodiments, cylinders 800 are provided on the four sides of the rear template 400, and the piston rod ends of each cylinder 800 are respectively connected to sliders, and drive the sliders to move so that the four side cores 420 are gathered or separated. The cylinders 800 can be used to quickly position and demold the side cores 420, thereby improving production efficiency and preventing damage caused by the molding groove 423 and the buckle group 110 not being separated during demolding.

[0037] It should be noted that the base 200 is provided with a ejector assembly, which passes through the rear template 400 and connects to the lower mold core 410 to drive the lower mold core 410 to eject the molded front cover 100. The ejector assembly facilitates rapid demolding and improves processing efficiency.

[0038] The utility model also provides a front cover manufacturing device, which uses the front cover injection mold as described above.

[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
