Description

A kind of mould Lifting Device

Technical field

The utility model relates to a kind of mould, particularly relates to a kind of various diels use mould Lifting Device that are suitable for.

Background technology

At present, the Lifting Device behind the mould product flange roughly can be divided into four classes:

1, lever connecting rod structure, its advantage: simple in structure, certain applicability is arranged.Its weak point: effect is relatively poor, and production efficiency is low, and labour intensity is big;

2, simple and easy bullet roof construction, its advantage: simple being suitable for; Shortcoming: presentation quality is relatively poor, and guiding accuracy is lower;

3, monoblock type bullet roof construction, its advantage: efficient height, precision height.Its weak point: processing difficulties, it is bigger to adjust difficulty;

4, airlift mechanism, its advantage: precision height, use are extensively.Its weak point: take installing space, cost is higher.

The utility model content

The purpose of this utility model is to overcome deficiency of the prior art, provides that a kind of applicability is wide, guiding accuracy is high, easy adjustment, the small and exquisite mould Lifting Device of volume.

The purpose of this utility model is achieved by following technical proposals: comprise guide pillar, sleeve, liftout spring, the ejection block securing member at the band end; Described guide pillar is installed in the sleeve, and the liftout spring is set between the two; The opening part of described sleeve is installed limited block by the limited block securing member; Described guide pillar is provided with the breach step that stops guide pillar rotation and the up stop of restriction guide pillar away from the position of the corresponding limited block in the outside of an end of liftout spring.

Described guide pillar adopts the ejection block securing member that ejection block is installed away from an end of liftout spring.

Described liftout spring adopts the compression spring.

The working face of described ejection block and the contact-making surface of product coupling.

Compared with prior art, the utlity model has following advantage: simple and reasonable, be easy to install and adjust, the operating accuracy height, the production efficiency height, labour intensity is low, and cost is low.Be suitable in all stamping dies, using.

Description of drawings

Accompanying drawing is the utility model one example structure schematic diagram.

Among the figure: 1-ejection block, 2-guide pillar, 3-sleeve, 4-liftout spring, 5-pore, 6-limited block, 7-limited block securing member, 8-breach step, 9-ejection block securing member.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

With reference to accompanying drawing, the utility model comprises guide pillar 2, sleeve 3, liftout spring 4, the ejection block securing member 9 at the band end; Described guide pillar 2 is installed in the sleeve 3, and liftout spring 4 is set between the two; The opening part of described sleeve 3 is installed limited block 6 by limited block securing member 7; Described guide pillar 2 is provided with the breach step 8 that stops guide pillar 2 rotations and restriction guide pillar 2 up stops away from the position of the corresponding limited block 6 in the outside of an end of liftout spring 4.

Described guide pillar 2 adopts ejection block securing member 9 that ejection block 1 is installed away from an end of liftout spring 4.

Described liftout spring 4 adopts the compression spring.

The working face of described ejection block 1 and the contact-making surface of product coupling.

Pore 5 is fabrication hole simultaneously.

The utility model provides a kind of assembled Lifting Device, has realized flexible and convenient installation, liftout accurately and effectively, can solve the liftout problem behind the finished product flange after the punch forming well.

Change the ejection block 1 of different operating face, to adapt to the finished product after the various punch formings.

In the present embodiment, liftout spring 4 adopts the compression spring.Constitute the structure of compression spring in conjunction with guide pillar 2, sleeve 3.The compression spring is positioned in the guide pillar 2 of band blind hole in advance, follows guide pillar and spring are inserted the band sleeve 3 at the end in the lump, adopts limited block securing member 7 that limited blocks 6 are installed then, rotates in sleeve 3 with up stop and the prevention guide pillar 2 that limits guide pillar 2.Said modules is installed in the diel.

The course of work: touch ejection block 1 when patrix is descending earlier, compress spring stress simultaneously and be compressed gradually, ejection block 1 sinks to the precalculated position; During the patrix backhaul, under the active force of compression spring, ejection block 1 rises, with the die that ejects after the punch forming.

In addition, can also be according to actual needs, in diel, adopt the quantity and the installation site of a plurality of the utility model mould Lifting Device, and ejection stroke and Lifting Device height can be adjusted flexibly by changing spring and guide pin bushing length, and the working face of ejection block 1 is determined with the profile of specific product.

Claims (5)
