Description
TECHNICAL FIELD
[0001] The present application relates to the field of process equipment, more particularly, to a demolding tool. BACKGROUND
[0002] In the prior art, for edge closed structure and using male die to form composite product, the common demolding methods are as follows: one is that the negative angle of the profile surface is less than 0.5 degrees, the demolding method is to design a avoiding groove at the flange of the die, and a top die block is embedded above the avoiding groove when the product is laid. When demolding, the top die screw is rotated from below the flange avoiding groove and applies an upward force to the top die block, so as to push the product out of the die body. In this demolding method, the force is directly applied to the composite product, which is easy to cause damage such as delamination and splitting of the product. The second is that the negative angle of the profile surface is greater than 0.5 degrees, and the demolding method is to divide the die body into blocks, which can preferentially pull out the part of the die body without negative angle to leave a gap, and then pull out the remaining blocks in sequence. This demolding method can only be applied to the demolding of small size composite forming die such as ribs and covers. CONTENT OF THE UTILITY MODEL
