[0039] The shape and size of the upper mold base 11 match the shape and size of the lower mold base 21, and the shape and size of the upper mold core 12 match the shape and size of the lower mold core 22, so that during the mold closing process, the upper mold base 11 and the lower mold base 21 and the upper mold core 12 and the lower mold core 22 can fully cooperate and dock with each other to produce the battery cover 200.
[0040] The glue feeding mechanism 30 is installed on the upper mold 10, and is used for feeding glue, and is used for guiding molten plastic into the mold cavity.

[0041] A first glue inlet channel 31 is provided on the glue inlet mechanism 30, and the glue outlet of the first glue inlet channel 31 corresponds to the camera hole of the molded battery cover 200, that is, the molten plastic of the first glue inlet channel 31 flows out along the position of the upper mold core 12 corresponding to the camera hole of the battery cover 200; a second glue inlet channel 41 is provided on the inclined ejection mechanism 40, and the inclined ejection mechanism 40 is partially located at the position of the lower mold core 22 corresponding to the camera hole of the battery cover 200, so that the glue inlet of the second glue inlet channel 41 is connected with the glue outlet of the first glue inlet channel 31, and the molten plastic is guided to the mold cavity through the second glue inlet channel 41, and filled along the inner surface of the battery cover 200, so as to avoid glue inlet from the side of the battery cover 200 and no weld line will be generated.

[0042] The technical solution of the utility model guides the molten plastic to the camera hole passing through the molded battery cover 200 through the cooperation of the first glue feeding channel 31 of the glue feeding mechanism 30 and the second glue feeding channel 41 of the inclined lifting mechanism 40, and feeds the glue along the inner side of the battery cover 200, thereby avoiding the generation of weld lines on the surface of the battery cover 200 due to glue feeding from both sides of the battery cover 200, effectively improving the molding quality of the battery cover 200, and the surface of the battery cover 200 does not need to be sprayed and covered, thereby reducing the production process cost of the battery cover 200, and the mold structure is simple and the cost is low.
[0043] In one embodiment of the utility model, the glue feeding mechanism 30 includes a glue feeding ring 32 and a glue feeding cylinder 33, the glue feeding ring 32 is installed on the top of the upper mold base 11, the glue feeding cylinder 33 is installed in the upper mold base 11 and extends to the upper mold core 12, the upper mold core 12 is provided with a glue injection channel 121, the glue feeding ring 32 is connected to the glue feeding cylinder 33, the glue feeding cylinder 33 is connected to the glue injection channel 121, and the glue injection channel 121 is connected to the glue inlet of the second glue feeding channel 41.
[0044] In detail, the glue feeding mechanism 30 includes a glue feeding ring 32 and a glue feeding cylinder 33. The glue feeding ring 32 is arranged at the top of the upper mold base 11. The glue feeding ring 32 is formed with a glue feeding port. The glue feeding cylinder 33 is installed in the upper mold base 11. The glue feeding ring 32 is connected to the glue feeding.

The glue outlet of the glue feeding cylinder 33 is connected to the glue injection channel 121 of the upper mold core 12. The glue injection channel 121 of the upper mold core 12 is connected to the second glue feeding channel 41. That is, the glue feeding port of the glue feeding ring 32, the channel in the glue feeding cylinder 33 and the glue injection channel 121 of the upper mold core 12 jointly form a first glue feeding channel 31, which is convenient for guiding the molten plastic to the camera hole of the molded battery shell of the upper mold core 12.
[0045] In one embodiment of the utility model, the glue injection channel 121 includes an inlet section 1211, an extension section 1212 and a vertical section 1213 which are interconnected. The inlet section 1211 is connected to the glue feeding cylinder 33.

[0046] It is worth noting that the injection channel 121 of the upper mold core 12 includes an inlet section 1211, an extension section 1212 and a vertical section 1213. Figure 6 and Figure 8 The inlet section 1211 is connected to the glue feeding cylinder 33 to receive the molten plastic injected by the glue feeding ring 32 and the glue feeding cylinder 33. The extension section 1212 is extended along the horizontal direction of the upper mold core 12 to guide the molten plastic to above the position of the camera hole of the molded battery shell of the upper mold core 12. The molten plastic is then guided to the position of the camera hole of the molded battery shell of the upper mold core 12 by the vertical section 1213. The vertical section 1213 is connected to the second glue feeding channel 41 of the inclined top mechanism 40, so that the molten plastic can directly enter from the glue inlet of the second glue feeding channel 41 and enter the mold cavity from the glue outlet of the second glue feeding channel 41 to produce the battery cover 200.
[0047] The mold structure is simple. By designing a glue feed ring 32, a glue feed cylinder 33 and a glue injection channel 121 in the upper mold core 12 and cooperating with the upper mold base 11, the molten plastic can be injected from the camera hole of the upper mold core 12 corresponding to the battery cover 200, and the molten plastic is injected from the top surface of the mold cavity of the lower mold core 22 by the inclined top mechanism 40, and the glue is fed along the inner side surface of the battery cover 200 to produce the battery cover 200, which solves the problem that the glue injection from the side of the battery cover 200 will produce a weld line on the surface of the battery cover 200, improves the molding quality of the battery cover 200, and does not need to spray to cover the surface of the battery cover 200, thereby improving the production efficiency of the battery cover 200 and reducing the production cost.
[0048] In an embodiment of the present invention, the inlet of the inlet section 1211 is flared, and the extension section 1212 is opened along the top surface of the upper mold core 12 toward the bottom.
[0049] In detail, Figure 5The bottom surface of the glue inlet cylinder 33 contacts the top surface of the upper mold core 12, and the inlet section 1211 of the glue injection channel 121 is set in a circular expansion, which can better receive the glue out of the glue inlet cylinder 33. The extension section 1212 is opened along the top surface of the upper mold core 12 toward the bottom. The extension section 1212 can better connect with the inlet section 1211, so that the molten plastic can be better guided from the extension section 1212 to the vertical section 1213.

[0051] Specifically, the second glue inlet 41 of the tilting mechanism 40 is provided with a glue inlet 411 and two glue injection ports 412. The glue inlet 411 is connected to the glue outlet of the first glue inlet 31, and the molten plastic is injected into the mold cavity through the two glue injection ports 412. Since the production of the battery cover 200 requires the design of a gate of a certain length to meet the production requirements, but the gate length is too long, and the later removal of waste is more complicated and difficult, so two glue injection ports 412 are designed to meet the production requirements and facilitate the removal of waste, thereby improving the production efficiency of the battery cover 200.

[0058] In detail, a supporting step 422 is formed on the bull-horn gate insert 42, and the gate inclined ejector 43 is supported on the supporting step 422, so as to facilitate the coordination and positioning of the bull-horn gate insert 42 and the gate inclined ejector 43, and better guide the molten plastic to the mold cavity.

[0063] In addition, in the prior art, the mold is made into an inverted mold, and the hot nozzle is tilted from the middle to inject glue, which can solve the problem of generating weld lines on the surface of the battery cover 200, but the structure of the inverted mold is complex and the cost is high.
