Description

Novel rear mold lifter structure

Technical Field

The utility model relates to the technical field of dies, in particular to a novel rear die lifter structure.

Background

The conventional pitched roof structure of the existing mold is ejected by matching an pitched roof, a pitched roof positioning block and a pitched roof sliding seat with an ejector plate, and some ejector plates are pushed out and products requiring secondary ejection and tripping of internal buckling positions need to be matched by using the ejector pin, otherwise, mold stripping can not be achieved, so that the ejector plate needs to be used for the mold, the size is increased, and the production cost is increased.

Disclosure of Invention

In order to overcome the defects and shortcomings in the prior art, the utility model aims to provide a novel rear die inclined top structure, which solves the problem that the size of a die is increased due to the fact that a thimble is required to be used for demolding in certain products.

The utility model is realized by the following technical scheme:

a novel rear mold lifter structure comprises a rear mold core, a push plate, a rear mold base plate, a rear mold insert and a hook block, wherein the rear mold core, the push plate and the rear mold base plate are sequentially attached, the rear mold insert is fixedly arranged on the rear mold base plate, and the hook block is fixedly arranged on the push plate; the rear mold base plate is positioned between the hook block and the rear mold insert, the first through hole is formed in the rear mold base plate, a sliding seat is arranged in the first through hole in a sliding mode, the hook block extends into the first through hole and abuts against the lower end of the sliding seat, and a limiting groove communicated with the first through hole is formed in the lower end of the rear mold insert; the slide is also connected with an inclined top which penetrates through the rear die insert and protrudes into the rear die core.

The lower end of the first through hole is communicated with a second through hole, and the sliding seat is connected with a plug screw which extends into the second through hole in a protruding mode.

The plug screw sleeve is provided with a spring, and two ends of the spring are respectively connected with the sliding seat and the bottom end of the second through hole.

The number of the sliding seats, the number of the hook blocks and the number of the inclined tops are two, and the two sliding seats, the hook blocks and the inclined tops are symmetrically arranged relative to the rear mold insert respectively.

The utility model has the beneficial effects that:

the problem of some products lead to the mould volume increase because of must using thimble demolding is solved: according to the novel rear mold pitched roof structure, the rear mold insert is fixed on the rear mold seat plate, the hook block is fixed on the push plate, the shovel base pull plate is arranged on the floating plate, when a mold is opened, the push plate is pushed to move upwards through the injection molding machine, the hook block can hook the sliding seat to move upwards, and meanwhile, the pitched roof is driven to eject a product out of the rear mold insert. When the pitched roof retracts inwards for a certain stroke, the limiting groove at the bottom end of the rear mold insert limits the sliding block to ascend, and meanwhile, the hook block is separated from the sliding seat, so that the total stroke of the pitched roof is limited, and the mold stripping is completed.

The structure of the utility model has no thimble and thimble plate, and can reduce the size of the mould, thereby reducing the tonnage of the required injection molding machine and lowering the production cost.
