A wax cooler for a wax injection machine

Abstract

The invention belongs to the machinery field, particularly relates to a heat exchange device, and mainly relates to the processing technical field of a wax cooler of a wax injection machine. The wax cooler of the wax injection machine comprises a heat conduction oil cavity horizontally arranged and a spiral pipe formed through winding once and horizontally arranged, wherein the spiral pipe is arranged in the heat conduction oil cavity, the heat conduction oil cavity is a straight pile, a first end plate and a second end plate are respectively fixed at two ends of the straight pile, a wax feed channel, a heat conduction oil discharge channel and a temperature measurement hole are formed in the first end plate, a wax discharge channel, a heat conduction oil feed channel, another temperature measurement hole and a cold oil feed channel are formed in the second end plate, an inlet and an outlet of the spiral pipe are respectively communicated with the wax feed channel and the wax discharge channel, the heat conduction oil discharge channel and the heat conduction oil feed channel are communicated with the heat conduction oil cavity, and the cold oil feed channel is communicated with the heat conduction oil cavity. By adopting the structure, the wax cooler of the wax injection machine guarantees constant temperature effects, and then controls wax temperature well, and achieves stable performance for the wax injection machine.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a heat exchange device, mainly in the technical field of manufacturing a cooler. Background technique [0002] The existing wax injection machine cooler is a multi-section double-layer tube, and there is a gap between the double-layer tubes for medium circulation. When it is in use, it adopts a wave-shaped setting to reduce the occupied space. The manufacture of this heat exchange tube is relatively Complicated, especially the welding of the end and the bending part is difficult, and the manufacturing cost is high; the cooler on the wax injection machine is used for cooling and constant temperature of the wax to ensure that the wax can be injected into the mold smoothly, and the above cooler requires a long time for the wax to pass through. The distance between the wax and the air is large, and the accuracy of the wax temperature cannot be guaranteed; during the working process of the wa...
