Description

Technical Field

[0001] The utility model belongs to the technical field of automobile battery plastic shell injection molds, and in particular relates to an injection mold for processing automobile battery plastic shells. Background Art

[0002] Battery plastic shells are mostly formed by injection molding, which is done by filling hot raw materials into an injection cavity consisting of an upper mold and a lower mold to form a set battery plastic shell shape, then cooling the injection mold to shape the raw materials, and finally opening the injection mold to demold the battery plastic shell.

[0003] Patent No. CN217395630U discloses a battery plastic shell injection mold that can quickly cool down. The buffer block is set to slow down the speed of the coolant when it flows through the outer cooling cavity, thereby improving the utilization rate of the coolant. The baffle is set to slow down the flow speed of the high-speed wind, so that the cooling wind is in full contact with the heat exchange slot tube, thereby improving the utilization rate of the cooling wind.

[0004] However, when the actual automobile battery shell injection mold is cooled, the coolant is directly introduced into the cooling chamber, and the wind is blown directly to the outer wall of the mold. The mold is cooled by air and water at the same time. Adding a buffer plate inside the cooling box to change the flow rate of the coolant not only absorbs more heat, but also reduces the cooling speed of the mold. The coolant in the cooling chamber is not stirred during cooling, which is not conducive to the cooling and demolding of the mold. Utility Model Content
