Description

A sand core efficient cooling device

Technical Field

The utility model relates to the technical field of sand core casting production technology, in particular to a sand core high-efficiency cooling device.

Background Art

Sand cores are used to form the cavity in castings during casting production. The sand cores are fixed at specific positions in the sand molds before casting. After casting, the high-temperature liquid metal is cooled and formed through the sand core cooling device. The sand cores are broken to obtain the formed castings.

In the prior art, application No. 202320279439.7 discloses a sand core cooling device, including a conveyor, a bracket, a ventilation pipe and a cooling pipe. The cooling pipe is mounted above the conveyor through the bracket, and the partition layer in the cooling pipe divides the interior of the cooling pipe from top to bottom into an upper flow channel, an air flow channel and a lower flow channel. A plurality of cooling pipes are arranged in the air flow channel, and the two ends of the cooling pipe are connected to the upper flow channel and the lower flow channel respectively. A blower is connected to both ends of the air flow channel through a pipeline. The upper flow channel and the lower flow channel are connected to a coolant circulation pipeline. A plurality of ventilation pipes are distributed between the two cooling pipes along the length direction of the conveyor, and a plurality of air outlets are evenly opened on the ventilation pipe. The structure of the above device is complex, and multiple ventilation pipes and ventilation holes are set for use, which greatly increases the manufacturing cost of the equipment, and there is no special circulation structure, which greatly wastes the amount of coolant. The conveying of sand cores by conveyor belt will cause multiple sand cores to be unable to be fully cooled, and need to be transported to the conveyor belt again for rework and reprocessing, which is time-consuming and labor-intensive.

Currently, no effective solution has been proposed for the problems in the related technologies.
