Problems solved by technology

[0004] The present invention solves the problems caused by the difficulty in cleaning the internal structure of conventional molds, the high rate of loss and wear and corrosion, and the inability to reprocess the existing molded shell, which cannot be modified twice after casting, and cannot realize the production of complex internal structures and complex cross-sections. The cost is high and the maintenance cost is high; the existing blow molding or mechanical deformation and other methods have uneven pressure during the mold forming process, the surface of the produced sample is not smooth, and it is prone to fracture and damage; the existing mold has a single function and can only Carrying out one deformation can not be deformed multiple times according to the needs of users in temperature gradients, and the controllability is low, so as to provide a mold for shape memory polymer blister

Abstract

The invention relates to a mold used for plastic suction of shape memory polymers. By adoption of the mold used for plastic suction of the shape memory polymers, the defects that in the prior art, secondary modification cannot be achieved after a plastic shell is cast, and an internal complex structure and a complex variable section cannot be manufactured; the internal structure of a conventional mold is difficult to clean, the wastage and the wear corrosion rate are high, the cost is high due to the fact that reprocessing is not available, and the maintenance cost is high; by adoption of an existing blow molding or mechanical deformation way or other existing ways, the pressure is nonuniform in the mold forming process, the surface smoothness of a manufactured sample is poor, and fracture damage is likely to occur; and an existing mold is simplex in function, can only deform once and cannot deform multiple times based on the temperature gradient according to requirements of users, and the degree of controllability is low are overcome. The mold comprises an upper mold body and a lower mold body, wherein the upper mold body and the lower mold body are buckled together to form a cuboid, and a mold cavity is machined in the cuboid in the length direction. The mold is applied to the field of plastic suction of the shape memory polymers.

Description

technical field [0001] The invention relates to a shape memory polymer blister mould, in particular to a multi-brush deburring device with a gear box. Background technique [0002] Molds play an important role in traditional manufacturing and can be used for device forming and external winding. However, with the continuous advancement of demand and technology, the precision and cross-section complexity of molds are becoming more and more demanding. Traditional metal molds show In view of the disadvantages of difficulty in stripping, inability to reuse, and poor corrosion resistance, sand molds and plaster molds that have emerged later also have defects such as insufficient surface finish, low hardness and strength, and poor vibration resistance to varying degrees. [0003] Shape memory polymer is a special polymer material by molecular combination and modification of polymers. Under certain conditions, the material is given a certain shape under the action of the outside wo...
