The terms used in this specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] Please also refer to Figures 7 to 10 In one embodiment, a front mold 10 for producing a battery cover is formed with an injection groove 101, and the front mold is used to abut against the rear mold 20 to form an injection cavity 201. The front mold is provided with a sliding through hole 102, and the sliding through hole 102 is connected to the injection groove 101. The front mold is provided with a sliding protrusion 410 and a sliding connecting member 430, and the sliding connecting member 430 includes a sliding portion 431 and an abutting portion 432. The abutting portion 432 is convexly provided on the sliding portion 431, and the sliding portion 431 is connected to the sliding protrusion 410. The sliding portion 431 is located in the sliding through hole 102 and is connected to the sliding protrusion 410. The front mold is slidably connected, and the abutment portion 432 is located on the outside of the front mold; the front mold is used to abut against the rear mold 20 when molding the battery cover 20A, the position projection 410 is located in the injection cavity 201, the sliding portion 431 is located in the sliding through hole 102, and the abutment portion 432 abuts against the outer wall of the front mold; the sliding portion 431 is used to slide out of the sliding through hole 102 during demolding, so as to drive the position projection 410 to slide out of the injection groove 101 through the sliding through hole 102, and the abutment portion 432 leaves the outer wall of the front mold.

[0044] In the above-mentioned front mold 10 for producing battery covers, when the mold assembly 10A is injection molded, the position projection 410 and the sliding portion 431 are both slidably connected to the inner peripheral wall of the sliding through hole 102, that is, the sliding portion 431 is at the same height as the position projection 410, avoiding the problem of the sliding portion 431 covering the extended portion of the battery cover 20A and causing a step difference. Similarly, the abutting portion 432 is located on the outside of the front mold, that is, the side wall of the front mold separates the abutting portion 432 from the extended portion of the battery cover 20A, avoiding the problem of the abutting portion 432 abutting against the extended portion of the battery cover 20A and causing a step difference, thereby ensuring the injection molding accuracy of the battery cover 20A.

[0045] Please also refer to Figures 3 and 4 For the traditional front mold, the sliding connector 23b abuts against the inner wall of the first sliding notch 22 and abuts against the rear mold, and the sliding connector 23b is protruded from the sliding protrusion 23a, so that the sliding protrusion 23a can easily slide relative to the side wall of the rear mold during the process of moving away from the injection cavity 201. Due to the gap between the rear mold and the front mold, the sliding protrusion 23a can easily cause wear to the battery cover 20A during the movement, affecting the injection molding accuracy.

[0046] Please also refer to Figures 7 and 8 , and in the front mold of the present application, the slide protrusion 410 is slidably connected to the inner peripheral wall of the sliding through hole 102, thereby avoiding the slide protrusion 410 from moving into the gap between the front mold and the rear mold 20 during the sliding process, that is, causing the slide protrusion 410 and the slide pin 420 to deviate from the moving trajectory, thereby reducing the slide protrusion 410 from wearing the extension groove 12 of the battery cover 20A, and reducing the slide pin 420 from wearing the slide pin hole 15 of the battery cover 20A, thereby ensuring the injection molding accuracy of the battery cover 20A.

[0047] Please also refer to Figures 9 and 10 as well as Figures 12 to 13In one embodiment, the front mold includes a first movable mold 300, a sliding mechanism 400 and a core-pulling mold 100; the first movable mold 300 is used to movably abut against the rear mold 20 to form an injection cavity 201, the sliding through hole 102 is opened on the side wall of the first movable mold 300, and the abutting portion 432 is located on the outside of the first movable mold 300, and the abutting portion 432 movably abuts against the side wall of the first movable mold 300; the side wall of the first movable mold 300 is opened with a first sliding channel 301, and the abutting portion 432 is opened with a second sliding channel 402, and the first sliding channel 301 and the second sliding channel 402 are connected to form a guide column Sliding channel 103; the sliding protrusion 410 and the sliding connecting piece 430 are both arranged on the sliding mechanism 400, and the sliding mechanism 400 is also provided with a sliding drive assembly 440, and the power output end of the sliding drive assembly 440 is connected to the abutment part 432; the core pulling mold 100 is arranged on the side of the first movable mold 300 away from the rear mold 20, and the core pulling mold 100 is provided with a lateral guide column 120, and the lateral guide column 120 is slidably connected to the inner wall of the guide column sliding channel 103; when the first movable mold 300 moves toward or away from the core pulling mold 100, the lateral guide column 120 is slidably connected to the sliding connecting piece 430. It can be understood that when the mold assembly 10A is injected, the lateral guide column 120 is arranged in the second sliding channel 402 to fix the slide protrusion 410 in the injection cavity 201, so that the extension groove 12 of the battery cover 20A is formed; after the injection molding is completed, the lateral guide column 120 slides in the guide column sliding channel 103 of the slide protrusion 410 until the lateral guide column 120 is separated from the slide protrusion 410, so that the power output end of the subsequent slide drive assembly 440 drives the slide protrusion 410 to move away from the injection cavity 201 until the slide protrusion 410 leaves the injection cavity 201, so that the slide protrusion 410 leaves the battery cover 20A, so that the battery cover 20A can be demolded subsequently.

[0048] Please also refer to Figures 9 and 10 In one embodiment, the slide drive assembly 440 is an oil cylinder or a pneumatic cylinder.

[0049] Please also refer to Figure 5 、 Figures 7 and 8 In one embodiment, the slide mechanism 400 further includes a slide pin 420, which is disposed on the side of the slide protrusion 410 facing away from the slide connector 430. It is understood that the slide pin 420 is used to form the slide pin hole 15 of the battery cover 20A. The slide pin 420 is disposed on the side of the slide protrusion 410 facing away from the slide connector 430 to prevent the slide pin 420 from being blocked by the sliding through hole 102 when the power output end of the slide drive assembly 440 drives the slide protrusion 410 and the slide pin 420 to move. This allows the slide protrusion 410 and the slide pin 420 to leave the injection cavity 201 and the battery cover 20A, facilitating subsequent demolding of the battery cover 20A.

[0050] Please also refer to Figures 7 and 8 In one embodiment, the axis of the slider pin 420 is in the same direction as the movement direction of the power output end of the slider drive assembly 440. It is understood that the axis of the slider pin 420 is in the same direction as the movement direction of the power output end of the slider drive assembly 440 to avoid the slider pin 420 being blocked by the sliding through hole 102 when the power output end of the slider drive assembly 440 drives the slider protrusion 410 and the slider pin 420 to move, thereby allowing the slider protrusion 410 and the slider pin 420 to leave the injection cavity 201 and the battery cover 20A, thereby facilitating subsequent demolding of the battery cover 20A.

[0051] Please also refer to Figures 9 and 10 In one embodiment, the core-pulling mold 100 is further provided with a positioning template 110, which is connected to the lateral guide pillars 120. The positioning template 110 is used to connect with the fixed component of the beer machine. It can be understood that the fixed component of the beer machine fixes the positioning template 110 to prevent the lateral guide pillars 120 from moving. At the same time, the first driving component of the beer machine drives the rear mold 20 to move away from the positioning template 110. The first movable mold 300 abuts against the rear mold 20 under the action of gravity, so that the first movable mold 300 and the sliding mechanism 400 also move away from the positioning template 110, thereby causing the lateral guide pillars 120 to slide relative to the inner peripheral wall of the guide pillar sliding channel 103 until the lateral guide pillars 120 are separated from the sliding protrusions 410, so that the subsequent sliding drive assembly The power output end of 440 drives the slide protrusion 410 to move in the direction away from the injection cavity 201 until the slide protrusion 410 leaves the injection cavity 201, so that the slide protrusion 410 leaves the battery cover 20A, so that the battery cover 20A can be demolded later; and under the action of gravity, the first movable mold 300 and the second movable mold 600 are relatively fixed to fix the battery cover 20A in the injection cavity 201, reducing the damage to the battery cover 20A caused by the slide protrusion 410 and the slide pin 420 when they are away from the injection cavity 201, thereby ensuring the quality of the battery cover 20A.

[0052] See also Figure 20 In one embodiment, the first movable mold 300 is provided with a front mold inserting pin 130, which is inserted into the injection cavity 201 of the injection groove 101. It can be understood that when the first movable mold is separated from the second movable mold, the injection cavity 201 is opened. At this time, the battery cover is placed on the second movable mold and moves away from the positioning template 110 with the second movable mold, thereby separating the battery cover from the front mold inserting pin 130 and the injection cavity 201, thereby realizing the demolding of the battery cover 20A.

[0053] See also Figure 3 and Figure 11In a traditional mold, a second sliding notch is opened in the front mold, and a molding protrusion 310 and a slider 150 are provided in the front mold. The slider 150 is protruded from the molding protrusion 310, and the slider 150 is slidably set in the second sliding notch so that the slider 150 is exposed in the second sliding notch; when the mold assembly 10A is injection molded, the molding protrusion 310 is located in the injection cavity 201, and the slider 150 is located on the inner peripheral wall of the second sliding notch and abuts against the rear mold 20. Since the slider 150 is protruded from the molding protrusion 310, the slider 150 not only covers the extension groove 12, but also covers the side wall where the extension part is located, thereby forming a step difference, which makes the injection molding accuracy of the battery cover 20A low. In order to avoid the problem that the battery cover 20A causes a step difference due to the slider 150 abutting against the extension portion during injection molding, thereby reducing the injection molding accuracy, in one embodiment, the first movable mold 300 is further provided with a molding protrusion 310, and the molding protrusion 310 is movably arranged in the injection molding groove 101, the first movable mold 300 is provided with a sliding groove 303 and a through hole 302 connected to the injection molding groove 101, the through hole 302 is connected to the sliding groove 303, the molding protrusion 310 is passed through the through hole 302 and is slidably connected to the first movable mold 300; the core pulling mold 100 is further provided with a front mold shovel base 140 and a slider 150, the slider 150 is slidably arranged in the sliding groove 303, the slider 150 is fixedly connected to the molding protrusion 310, the front mold shovel base 140 is connected to the positioning template 110, the slider 150 is provided with a first sliding inclined hole 104, the first A movable mold 300 is provided with a second sliding inclined hole 304 connected to the sliding groove 303, and the front mold shovel base 140 is slidably set in the second sliding inclined hole 304 and the first sliding inclined hole 104; when the first movable mold 300 moves in the direction away from the positioning template 110, the front mold shovel base 140 slides relative to the second sliding inclined hole 304 and the first sliding inclined hole 104 respectively to drive the slider 150 to move in the direction away from the injection cavity 201, so that the molding protrusion 310 slides away from the injection groove 101; when the first movable mold 300 moves in the direction close to the positioning template 110, the front mold shovel base 140 slides relative to the second sliding inclined hole 304 and the first sliding inclined hole 104 respectively to drive the slider 150 to move in the direction close to the injection cavity 201, so that the molding protrusion 310 is located in the injection groove 101.It can be understood that when the mold assembly 10A is injection molding, the molding protrusion 310 is located in the injection molding cavity 201; after the injection molding is completed, the fixing component of the beer machine fixes the positioning template 110 to prevent the front mold shovel base 140 from moving. At the same time, the first driving component of the beer machine drives the rear mold 20 to move in the direction away from the positioning template 110, and the first movable mold 300 abuts against the rear mold 20 under the action of gravity, so that the first movable mold 300 and the slider 150 move, and then the front mold shovel base 140 guides the slider 150 to move along the inclined surface of the front mold shovel base 140 until the slider 150 leaves the injection molding cavity 201 for the subsequent battery cover 20A demolding; the slider 150 is located outside the through hole 302, that is, the side wall of the first movable mold 300 separates the slider 150 from the extended portion of the battery cover 20A, avoiding the problem of step difference caused by the slider 150 abutting against the extended portion of the battery cover 20A, thereby ensuring the injection molding accuracy of the battery cover 20A.
