In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0052] Example 1

[0053] Referring to Figures 1-9 As shown, a glove processing blow molding mold with cooling function is provided, which comprises a mold body 100 and a cooling device 200 arranged inside the mold body 100. The mold body 100 comprises a mold bottom shell 110 and a mold top shell 120 arranged directly above the mold bottom shell 110. The mold top shell 120 and the mold bottom shell 110 are symmetrical structures. A model groove 111 is formed on the surface of the mold bottom shell 110. A blow molding hole 112 is formed on one end of the model groove 111. A through hole 113 is formed at the bottom of the blow molding hole 112. An installation cavity is formed at the bottom of the mold bottom shell 110. A refrigeration fin 114 is arranged in the installation cavity. A cooling cavity 115 is formed inside the mold bottom shell 110. An exhaust hole 116 is formed in the side wall of the mold bottom shell 110 and communicates with the cooling cavity 115. The cooling device 200 at least comprises:

[0054] A heat insulation assembly 210, which comprises a partition plate 211 arranged in the cooling cavity 115. The partition plate 211 divides the cooling cavity 115 into a refrigeration cavity and a heat dissipation cavity. The refrigeration cavity is located below the partition plate 211, and the heat dissipation cavity is located above the partition plate 211. A ventilation hole 213 is formed on the surface of the partition plate 211, which is used to communicate the refrigeration cavity and the heat dissipation cavity.

[0055] A flow guide assembly 220, which comprises a connecting column 221 sliding in the through hole 113. A sleeve rod 222 is connected to the bottom of the connecting column 221. A return spring 223 is arranged on the outer periphery of the sleeve rod 222. A sleeve 224 is slidingly connected to one end of the sleeve rod 222. The sleeve 224 is fixed to the bottom of the refrigeration cavity. The excess gas in the model groove 111 can be guided into the cooling cavity 115 by the flow guide assembly 220, so as to reasonably utilize the gas and improve the demolding efficiency.

[0056] In use, the mold top shell 120 is placed on the top of the mold bottom shell 110. The blow molding machine enters the model groove 111 through the blow molding hole 112. The pressure generated by the blow molding machine during the blow molding process causes the model to be blown open and collide. At this time, the pressure generated by the excess gas pushes the connecting column 221 to move downward. The connecting column 221 moves downward to deform the return spring 223. The connecting column 221 is separated from the through hole 113. At this time, the gas enters the refrigeration cavity through the through hole 113. The refrigeration fin 114 works to cool the refrigeration cavity. Therefore, the gas in the refrigeration cavity becomes cool. The cool gas enters the heat dissipation cavity through the ventilation hole 213 and contacts the outer wall of the model groove 111, so that the model groove 111 is cooled, and the gas is reasonably utilized.

[0057] In addition, in order to prolong the time of the gas contacting with the refrigeration cavity and improve the refrigeration efficiency of the gas, a plurality of flow guide plates 214 are arranged at the bottom of the partition plate 211 in the refrigeration cavity, the plurality of flow guide plates 214 are arranged in a cross manner, for prolonging the time of the gas passing through the refrigeration cavity, one end of part of the flow guide plates 214 is in contact with one end of the inner wall of the mold bottom shell 110, the other end of part of the flow guide plates 214 is in contact with the other end of the inner wall of the mold bottom shell 110, so that the plurality of flow guide plates 214 form an "S" shaped channel, thereby increasing the time of the gas contacting with the refrigeration cavity.

[0058] Further, in order to prevent the service spring 223 from reducing the service life due to the long time contact with the high-temperature gas, an outer periphery of the connecting column 221 is sleeved with a mounting block 225, the mounting block 225 has a tapered structure with a small diameter at the top and a large diameter at the bottom, when the gas passes through the through hole 113, the gas blows to the outer wall of the mounting block 225, the inclination of the outer wall of the mounting block 225 guides the gas and diffuses the gas to the four directions, thereby avoiding the direct contact between the gas and the service spring 223.

[0059] Still further, in order to improve the heat dissipation efficiency of the mold body 100, a temperature insulation cavity is arranged in the partition plate 211, and a temperature insulation layer 215 is arranged in the temperature insulation cavity, for insulating the temperature between the refrigeration cavity and the heat dissipation cavity, when the high-temperature gas enters the refrigeration cavity, the high-temperature gas will not transmit the temperature to the heat dissipation cavity through the partition plate 211, which means that the gas after being cooled will not heat up quickly when entering the heat dissipation cavity.

[0060] Embodiment 2

[0061] In order to realize the secondary utilization of the exhaust gas, the following improvements are made on the basis of Embodiment 1:

[0062] Please refer to Figure 10 As shown in the figure, the side wall of the mold bottom shell 110 is provided with a return pipe 230, one end of the return pipe 230 passes through the mold bottom shell 110 and communicates with the heat dissipation cavity, the other end of the return pipe 230 passes through the mold bottom shell 110 and communicates with the connecting pipe 212, when the gas in the heat dissipation cavity is exhausted, the gas enters the connecting pipe 212 again through the return pipe 230, because the exhaust gas is cooled, the temperature of the exhaust gas will be lower than the temperature of the gas in the mold groove 111, thereby improving the cooling efficiency of the mold body 100, and achieving the reasonable utilization of the gas.

[0063] Embodiment 3

[0064] In order to prevent the gas from running out of the exhaust hole 116 when the blow molding machine is pulled out from the blow molding hole 112, the following improvements are made on the basis of Embodiment 1:

[0065] Please refer to Figure 11As shown in the figure, the outer wall of the mold bottom shell 110 is provided with a plurality of mounting holes 240 at the outer periphery of the air exhaust hole 116, and a mounting spring 241 is arranged in the mounting hole 240. One end of the mounting spring 241 is connected with a sliding rod 242, the sliding rod 242 slides in the mounting hole 240, one end of the sliding rod 242 is fixedly connected with a disc 243. When the blow molding machine continuously injects air, the pressure in the heat dissipation cavity is too large, and the pressure pushes the disc 243 to make the gas exhaust. When the blow molding machine stops blowing, the mounting spring 241 drives the sliding rod 242 to reset, and the sliding rod 242 is attached to the air exhaust hole 116 to prevent the cooled gas from flowing out of the air exhaust hole 116, which affects the cooling performance of the mold body 100.

[0066] Embodiment 4

[0067] In order to facilitate the opening of the mold bottom shell 110 and the mold top shell 120, the following improvements are made on the basis of embodiment 1:
