[0031] The utility model is further described below in conjunction with embodiments.

[0032] Embodiment 1:

[0033] In order to solve the problem that most of the existing injection molding devices have a relatively simple structure, when the lithium battery needs to be demoulded after processing, the edge of the lithium battery may stick to the inside of the mold, which is inconvenient to use. Therefore, the following solution is disclosed. For details, please refer to Figure 2 and Figure 3The top of the lower mold 11 and the bottom of the sliding plate 2 are both provided with contact grooves 131, and the contact blocks 13 and the contact grooves 131 are both provided with multiple groups, and the other ends of the multiple corresponding contact blocks 13 extend to the corresponding lower mold 11 and the interior of the upper mold 21, respectively. The other ends of the contact blocks 13 are fixedly connected to the connecting plate 132, and the top of the connecting plate 132 is fixedly connected to the return spring 133, and the other end of the return spring 133 is fixedly connected to the lifting block 134, and the other ends of the multiple lifting blocks 134 extend to the inner side of the corresponding lower mold 11 and the bottom of the upper mold 21. When the lithium battery to be processed needs to be placed in the lower mold 11, the knob 121 can be turned at this time, and the knob 121 drives the threaded rod 1 22 rotates to make the sliding block 123 move, and the lower mold 11 is moved out from the inner side of the fixed base 1. At this time, the lithium battery can be placed inside the lower mold 11 for injection molding. When the operation is completed, the sliding plate 2 drives the upper mold 21 to separate from the lower mold 11. Since the multiple groups of contact blocks 13 lose their pressing force, the contact blocks 13 move inside the contact groove 131 under the joint action of the connecting plate 132 and the return spring 133, thereby making the multiple groups of lifting blocks 134 move on the inner side of the lower mold 11 and the bottom of the upper mold 21. At this time, the auxiliary demoulding operation can be performed, so that the edge of the lithium battery can be assisted to lift up during demoulding, thereby improving the use effect.

[0034] Embodiment 2:

[0035] In order to solve the problem that the existing injection molding device is generally cooled by direct air cooling, which is slow and cannot perform demoulding operation more quickly, affecting the efficiency of the device, the following solution is disclosed. For details, please refer to Figure 4 and Figure 5, a cooling mechanism 15 is also fixedly connected to the top of the fixed base 1, a condenser 151 is fixedly connected to the inside of the cooling chamber 14, the cooling mechanism 15 matches the condenser 151, a conductive sheet group 152 is also fixedly connected to the inside of the fixed base 1, the sliding block 123 is made of conductive material, and the sliding block 123 matches the conductive sheet group 152, a driving motor 153 is also fixedly connected to the inside of the fixed base 1, the driving motor 153 and the cooling mechanism 15 are both electrically connected to the conductive sheet group 152, a reciprocating screw 154 is fixedly connected to the output end of the driving motor 153, a fan module 155 is threadedly connected to the outer side of the reciprocating screw 154, and the fan module 155 is slidably connected to the bottom of the condenser 151, when the lithium battery inside the lower mold 11 needs to be cooled to facilitate faster demoulding, the cooling mechanism 15 is started at this time, and the cooling mechanism The mechanism 15 cools the liquid inside the condenser 151 so that the condenser 151 can emit cold air. At this time, the drive motor 153 is started, and the drive motor 153 drives the reciprocating screw 154 to rotate, so that the fan module 155 reciprocates inside the fixed base 1, so that the cooling and cold air dissipation rate of the condenser 151 can be faster, thereby improving the cooling rate of the lithium battery. When the user turns the knob 121 to move the lower mold 11 on the top of the fixed base 1, the sliding block 123 is disengaged from the conductive sheet group 152, so that the drive motor 153 and the cooling mechanism 15 lose power, which can prevent the cooling mechanism 15, the drive motor 153 and the fan module 155 from starting when demolding, thereby saving energy, achieving the effect of faster demolding of the lithium battery, and improving the use efficiency of the device.
