Description

TECHNICAL FIELD

[0001] The utility model relates to a material head removing mechanism, and particularly relates to a shell automatic adsorption material head removing mechanism. BACKGROUND

[0002] The injection molding shell is a plastic part obtained by injecting molten plastic into a plastic product mold through pressure and cooling. After molding, the injection molding part will have gate residues of different sizes, i.e., material heads. The conventional operation is to remove the part from the injection molding machine and transfer it to the next process, and then remove the material heads by corresponding equipment and manual operation. When manual operation is adopted, it is difficult to unify the positions of multiple material heads on the shell, and the labor cost is high, and the production efficiency is low. Therefore, equipment is usually used to improve the efficiency. However, when the equipment is used to remove multiple material heads, it is a difficult problem to position the material head clamping mechanism and each material head on the shell. The deviation of the material head cutting position can easily lead to unqualified products, and even cause damage to the shell, affecting the quality stability and production efficiency of the shell.
