Background

The traditional secondary demoulding action is that two groups of row bit groups (a large row bit and a small row bit) are respectively driven to move by two groups of inclined guide pillars through mould opening sequence action, so that secondary demoulding and core pulling are realized, the large row bit is kept to move while the small row bit stops moving, and after the small row bit moves for a certain distance, the large row bit and the small row bit move simultaneously. However, the main drawbacks of this method are: if the large row position and the small row position are driven by the two groups of inclined guide columns, a mold action control assembly needs to be added, the thickness of a template needs to be increased, and the mold opening stroke is increased.

In the prior art, two line position groups can be driven to move by a group of inclined guide posts or an oil cylinder, the movement of a large line position is limited mainly by a positioning glass bead or a limiting clamp, and after a small line position moves for a certain distance, the large line position is driven to overcome the limited resistance of the positioning glass bead or the limiting clamp so that the large line position and the small line position move together, thereby achieving the action of secondary demoulding. The main drawbacks of this method are: if the limiting devices such as the positioning glass beads or the limiting clamps limit the large-row position to realize the secondary demoulding action, the limiting devices such as the positioning glass beads or the limiting clamps have virtual positions, so that the large-row position cannot be completely ensured to stop moving.
