[0015] (Three) beneficial effects

[0016] When the mold needs to be shelled, the memory spring in the push-out mechanism is used for one-time ejection. When the mold is initially poured, the memory spring becomes soft due to heat. When the mold cools down, the memory spring also cools down. The cooled memory spring becomes hard and restores its original shape, which ejects the mold by a certain length, achieving the effect of preliminary pushing out. Subsequently, the mold can be ejected twice through the extrusion mechanism, avoiding the effect of incomplete shelling at one time. The second ejection can effectively reduce the deformation and scratches of the product, ensure the appearance and size precision of the finished product, especially for complex-shaped parts. Through the setting of the cooling mechanism, the distance of the cooling mechanism close to the mold is adjusted to control the cooling temperature. Controlling the cooling temperature can shorten the cooling time after molding and speed up the demolding speed of the product, thereby increasing the production frequency. Uniform cooling can reduce surface defects, thereby improving the appearance quality of the finished product. BRIEF DESCRIPTION OF DRAWINGS
