Front mold back-off demolding optimization structure

Abstract

The utility model relates to an optimized structure for demoulding a back-off part of a front mould. An existing core pulling structure driven by an oil cylinder is complex in structure, if the oil cylinder stops working and is not found in time, a product directly collides with the core pulling structure during demolding, the risks of mold damage and material waste exist, and the follow-up cleaning cost is increased. The structure comprises a rear mold sliding block arranged at the back-off structure of the product, and is characterized in that a front mold elastic block which also abuts against the back-off structure of the product is arranged on one side of the rear mold sliding block, a drag hook is arranged below the front mold elastic block, the drag hook limits the elastic block to move in the longitudinal direction during mold closing, and when the mold is opened, the elastic block can move in the longitudinal direction. And the front mold elastic block is separated from the drag hook after moving for a certain distance along the demolding direction of the inverted buckle of the product. Under the condition that the spatial position of an existing mold product is not changed, a demolding structure at the inverted buckle is changed into a combined structure of the front mold elastic block and the rear mold sliding block, and a mechanical structure is adopted for demolding, so that the risk during actual production of the mold is reduced, and the problem that the mold structure is complicated is also solved.

[0018] The utility model will be further described in connection with the drawings and specific embodiment.

[0019] As Figures 2-5 Shown in a kind of front mould reverse buckle demoulding optimization structure, including the rear mould sliding block 7 of setting in product 1 reverse buckle structure, located in the rear mould sliding block one side and set up the front mould elastic block 2 of also abutting product reverse buckle, the lower portion of front mould elastic block 2 is provided with draw hook 6, the draw hook 6 limits the longitudinal movement of elastic block 2 when mould is closed, when mould is opened, front mould elastic block 2 is moved a distance in the product reverse buckle demoulding direction and then separates from the draw hook 6.

[0020] In one embodiment, the lower portion of front mould elastic block is provided with elastic block assembly 5, the inner end of the elastic block assembly is provided with horizontal groove, and the draw hook is clamped in the horizontal groove. The draw hook is clamped in the horizontal groove in the initial state to limit the longitudinal movement of elastic block 2 when mould is closed.

[0021] Specifically, a longitudinal through groove is arranged at the center of the front mould elastic block, a limit screw 3 is arranged in the through groove, a spring 4 is arranged on the limit screw 3, and the lower end of the spring abuts against a stopper in the through groove.
