Description

Technical Field

[0001] The utility model relates to the field of injection molding tooling, in particular to an injection molded part gate residual side shear regulating mechanism. Background Art

[0002] like Figure 1 The protective cover product shown is a protective cover for installation on automobile exhaust valves to prevent dust, dirt, or corrosive objects from invading the interior of the exhaust valve. After the protective cover is injection-molded, the very small plastic residue from the gate on the top of the cover needs to be removed to produce a qualified finished product. The traditional method of removing the gate residue is manual, but this method has very low production efficiency. Therefore, a gate residue side-shearing device has been developed, with multiple pneumatic shears fixedly connected to both sides of the side-shearing device. A five-axis robot removes the protective cover product from the injection molding machine using a suction cup mechanism and places it on the side-shearing device. The pneumatic shears are activated and automatically cut off the gate residue. Because different models of protective cover products have different sizes, the existing fixed pneumatic shears cannot be adjusted in height and direction and can only adapt to a single model of protective cover. Therefore, a new side-shearing adjustment mechanism for gate residues of injection molded parts is needed. Utility Model Content
