Annealing device for plastic products

Abstract

The invention discloses an annealing device for plastic products. The annealing device comprises a box body, wherein a work box is fixedly connected between the two opposite sides of an inner wall ofthe box body through a fixing plate, and a motor is fixedly connected with the bottom of the inner wall of the box body; the output shaft of the motor is fixedly connected with a shelf through a transmission and a rotating device, and the bottom of the outer wall of the box body is fixedly connected with a bearing plate; one side of the top of the bearing plate is fixedly connected with an oil tank, and one side, close to the oil tank, of the bottom of the inner wall of the box body is fixedly connected with an oil pump; one side of the top of a fixing plate is fixedly connected with a circulating air pump, and an air heater is fixedly connected between the two opposite sides of the outer wall of the work box and the inner wall of the box body through a supporting plate; the bottom of theinner wall of the work box is fixedly connected with a heating disc, and one side of the top of the inner wall of the box body is fixedly connected with a control box. The invention relates to the technical field of plastic product processing. The annealing device for the plastic products has the advantages of simple operation, optional annealing method, stable annealing temperature, ensuring of annealing quality and improvement on processing efficiency.

Description

technical field [0001] The invention relates to the technical field of plastic product processing, in particular to an annealing device for plastic products. Background technique [0002] In the production and molding process of injection molded products, due to the uneven plasticization of raw materials or the uneven temperature of the mold during injection molding, the cooling rate of the product is inconsistent during molding, resulting in uneven crystallization, orientation and shrinkage of the product, resulting in the product. Internal stress, due to the effect of internal stress in the product, the performance of the product changes or deformation or cracks occur during use or storage. For large deformation or cracking, annealing treatment is required for some products after molding. Generally, the annealing treatment is to immerse the products in hot oil or hot water, or in the hot air circulation, and adjust the annealing temperature according to the different types...
