II, the working principle is as follows:
fig. 7, 8 and 9 show the secondary parting and secondary pushing operation. Fig. 7 shows a state before the mold is opened, when the mold is opened, the fixed mold plate (295) is separated from the movable mold plate (305) first, and when the movable mold plate (305) is separated from the fixed mold plate (295), the first parting is completed. And the movable mould part continues to move backwards, and the product is pulled to the movable mould side. As shown in fig. 8, at this time, the return needle (135) starts to move, because the front end of the sliding block (145) is clamped in the groove (215) of the return needle (135), and the sliding block (145) is connected with the movable template (305), the movable template (305) and the limit screw (335) move together with the return needle (135) under the driving of the sliding block (145), and the supporting plate (325) is stationary, so that the movable template (305) is separated from the supporting plate (325), thereby realizing the second parting; meanwhile, the insert (365) is fixed on the support plate (325) and is stationary, so the movable die core (405) plays a role of pushing the product (395) to push the product (395) out, and the first pushing-out of the die is realized. When the inclined surface (185) on the sliding block (145) is overlapped with the inclined surface (265) on the wedge block (155), the movable die plate (305) still moves for a certain distance along with the return needle (135), and the sliding block (145) cannot continuously move upwards along with the return needle (135) under the resistance of the inclined surface (265) on the wedge block (155). At the moment, the sliding block starts to slide along the T-shaped groove (255) until the front end of the sliding block (145) completely exits the groove (215), the stroke of the limiting screw (335) is also completed, and the movable template (305) stops moving. Under the action that the ejector rod of the press pushes the ejector pin plate, the return needle (135) continues to move, at the moment, the ejector pin (345) moves along with the ejector pin, the product (395) also moves upwards under the pushing of the ejector pin (345), at the moment, the insert needle (385) at the inverted buckle position (375) finishes the stroke, the insert needle (385) stops moving due to the completion of the stroke of the insert needle (385), and then the inverted buckle position (375) can be separated from the insert needle (385) by the elasticity of the inverted buckle position (375) under the action of the pushing force, so that the second pushing is realized.
