The UG software was used to analyze the solid modeling,demoulding taper,and wall thickness uniformity of the breast pump shield,and then the breast pump shield mould was de-signed.According to the four fasteners on the inner wall of the shield,a combination slider struc-ture driven by a dovetail groove block was designed,and the cooling channels with good effect were designed according to the mould structure.The mass production proved that the mould struc-ture was reasonable and the demoulding action was reliable.
