Efficient cooling device for plastic mold

The efficient cooling device comprises a base, a plastic mold body is fixedly connected to the center of the top of the base through bolts, a circulating pump and a flow guide frame are fixedly connected to the center of the interior of the base through bolts, and the circulating pump is located below the flow guide frame. And a first cooling liquid cavity channel is formed in the plastic mold body. According to the efficient cooling device for the plastic mold, through mutual cooperation of a first auxiliary flow pipe, a flow guide pipe and a second auxiliary flow pipe, part of cooling liquid of a flow guide frame can be input into a first cooling liquid cavity channel and a second cooling liquid cavity channel in different positions, and the cooling liquid with the low temperature is provided for the first cooling liquid cavity channel and the second cooling liquid cavity channel; therefore, the problem that the cooling effect of the rear half section of the plastic mold body is poor due to the fact that th
