According to the utility model, after the mold is opened, the main insert of the slide block can move upwards under the action of the spring force of the slide block spring, so that the buckling position formed at the inner end of the main insert of the slide block always keeps the same height while the slide block loosens the core, and the buckling position is effectively prevented from being pulled and deformed. The utility model has the advantages of simple structure, easy popularization and effective production cost saving.

Description

Mould slide block structure for preventing buckling position from deforming

Technical Field

The utility model relates to an injection mold, in particular to a mold sliding block structure for preventing buckling position deformation.

Background

The plastic injection mold is a tool for producing plastic products and has wide application. In the injection molding of plastic products, because some plastic products 100 (as shown in fig. 1) are relatively large and deep, a push plate is required to eject, at the moment when the movable mold plate and the fixed mold plate are opened, the plastic products 100 are left on the fixed mold side under the action of the holding force of the front mold, and the buckles are easily pulled and deformed.

Disclosure of Invention

The utility model aims to provide a die slide block structure for preventing a buckling position from deforming, which effectively prevents the buckling position from being pulled and deformed.

In order to achieve the purpose, the technical solution of the utility model is as follows:

the utility model relates to a die sliding block structure for preventing buckling position deformation, which comprises a sliding block seat, a sliding block main insert, a spring mounting plate, a sliding block spring and a sliding block screw rod; the middle part of take-up housing has seted up the spout, oblique guide post hole has been seted up in the outside of take-up housing, the inboard sliding connection of slider main mold insert can reciprocate in the spout at take-up housing middle part, the inboard of take-up housing is stretched out and is stretched to the die cavity in the outer end of slider main mold insert, the top and the cross-over connection at the take-up housing spout at the top of take-up housing are fixed to the spring mounting board, the lower extreme of slider screw rod passes rigid coupling at the top of slider main mold insert behind the spring mounting board, slider spring cup joints on the slider screw rod, the top surface at the countersunk head of slider screw rod and spring mounting board is leaned on respectively in the both ends of slider spring, play the effect of upwards stretching slider main mold insert along the take-up housing spout.

The inner end face of the main insert of the sliding block is provided with a buckling block which is square.

After the scheme is adopted, the slide block structure comprises the slide block seat, the slide block main insert, the spring mounting plate, the slide block spring and the slide block screw rod, after the mold is opened, the slide block main insert can move upwards under the action of the spring force of the slide block spring, so that the buckling position formed at the inner end of the slide block main insert is always kept at the same height while the slide block loosens the core, and the buckling position is effectively prevented from being pulled and deformed. The utility model has the advantages of simple structure, easy popularization and effective production cost saving.

The utility model is further described with reference to the following figures and specific embodiments.

Detailed Description

As shown in fig. 2, the utility model relates to a die slide block structure for preventing buckling deformation, which comprises a slide block seat 1, a slide block main insert 2, a spring mounting plate 3, a slide block spring 4 and a slide block screw rod 5.

The middle part of the sliding block seat 1 is provided with a sliding chute 11, the outer side of the sliding block seat 2 is provided with an inclined guide pillar hole 12, the inner side of the sliding block main insert 2 is connected in the sliding chute 11 in the middle part of the sliding block seat 1 in a sliding mode and can move up and down, a limiting mechanism for preventing the sliding block main insert 2 from moving transversely is arranged between the sliding block main insert 2 and the sliding block seat, the outer end of the sliding block main insert 2 extends out of the inner side of the sliding block seat 1 and extends to a cavity, a buckling block 21 is arranged on the inner end face of the sliding block main insert 2, and the buckling block 21 is square; the spring mounting plate 3 is fixed at the top of the sliding block seat 1 and bridged above the sliding chute 11 of the sliding block seat 1, the lower end of the sliding block screw rod 5 penetrates through the spring mounting plate 3 and then is fixedly connected to the top of the sliding block main insert 2, the sliding block spring 4 is sleeved on the sliding block screw rod 5, and two ends of the sliding block spring 4 respectively abut against the countersunk head of the sliding block screw rod 5 and the top surface of the spring mounting plate 3 to play a role of upwards stretching the sliding block main insert 2 along the sliding chute 1 of the sliding block seat.

As shown in fig. 2-5, the working principle of the die of the present invention is applied:

1, the sliding block seat 1 is connected on the fixed die plate 10 in a sliding way, the outer end of the sliding block seat 1 is abutted against an inclined wedge block 50, and an inclined guide post 20 is movably arranged in an inclined guide post hole 12 of the sliding block seat 2 in a penetrating way;

2. the die action is that a parting surface PL1 between the movable die plate 30 and the push plate 40 and a parting surface PL2 between the push plate 40 and the fixed die plate 10 are opened in sequence;

2. the push plate 40 pushes upwards to eject the plastic product 100; in the process that the push plate 40 is pushed out upwards, the main slide insert 2 moves upwards under the action of the spring force of the slide spring 4, so that the buckling positions formed at the inner end of the main slide insert 2 are always kept at the same height while the inclined guide post 20 drives the slide seat 1 to move outwards.

The above description is only a preferred embodiment of the present invention, and therefore should not be taken as limiting the scope of the utility model, which is defined by the appended claims and their equivalents and modifications within the scope of the description.
