Time-delay ejection mechanism

Technical Field

The utility model belongs to the technical field of dies, and particularly relates to a time delay ejection mechanism.

Background

When the mould in the existing market is used, the corresponding ejection device is required to eject the product inside, the ejector pin is required to be ejected in a delayed manner when the mould is ejected, but the ejector pin of the forming machine is arranged below the delayed ejector pin, so that the problem that the delayed ejector pin interferes with the ejector pin of the forming machine exists.

Disclosure of Invention

In order to solve the problems in the prior art, the utility model provides a time-delay ejection mechanism. The device has a simple structure, and the problem of interference between the lower part of the delay thimble and the ejection column of the forming machine is avoided by arranging the delay block; the delayed ejection is realized by the mutual matching of the ejection column, the delay block, the spring and the ejector pin.

In order to achieve the above purpose, the technical scheme of the utility model is a time delay ejection mechanism, which comprises a movable die core, an ejector pin plate, an ejector pin bottom plate and a bottom plate which are sequentially arranged from top to bottom; an ejection column is arranged in the bottom plate, one end of the ejection column extends into the thimble bottom plate, the thimble bottom plate is provided with a delay block, and a distance for delay movement of the delay block relative to the ejection column is arranged between the ejection column and the delay block;

one end of the delay thimble penetrates through the thimble plate and then contacts with the delay block, and the other end of the delay thimble extends into the movable mould core; one end of the thimble B penetrates through the thimble plate and then contacts with the thimble bottom plate, and the other end of the thimble B extends into the movable mould core; the ejector pin plate is provided with a groove, and the spring is arranged in the groove and connected with the delay block.

The radial dimension of one end of the delay thimble and one end of the thimble B are larger than the radial dimension of the other end of the delay thimble and one end of the thimble B.

Further, the delay block is U-shaped.

Further, the spring and the delay block and the ejection column are on the same axis.

By adopting the technical scheme, the utility model can obtain the following technical effects: the device has a simple structure, and the problem of interference between the lower part of the delay thimble and the ejection column of the forming machine is avoided by arranging the delay block; the delayed ejection is realized by the mutual matching of the ejection column, the delay block, the spring and the ejector pin.

Detailed Description

The utility model is described in further detail below with reference to the attached drawings and to specific embodiments: the utility model will be further described by way of examples.

As shown in fig. 1-2, the present embodiment provides a time-delay ejection mechanism, which includes a movable mold core 5, an ejector plate 6, an ejector bottom plate 7 and a bottom plate 8 sequentially arranged from top to bottom;

an ejection column 4 is arranged in the bottom plate 8, one end of the ejection column 4 extends into the thimble bottom plate 7,

the ejector pin bottom plate 7 is provided with a delay block 3, and a distance for delay movement of the delay block 3 relative to the ejector column 4 is arranged between the ejector column 4 and the delay block 3;

one end of the delay thimble 1 penetrates through the thimble plate 6 and then contacts with the delay block 3, and the other end of the delay thimble 1 extends into the movable mould core 5; one end of the thimble B9 penetrates through the thimble plate 6 and then contacts with the thimble bottom plate 7, and the other end of the thimble B9 extends into the movable mould core 5;

the ejector plate 6 is provided with a groove, and the spring 2 is arranged in the groove and connected with the delay block 3.

The spring 2 is used for ejecting and resetting.

One end radial dimension of the delay thimble 1 and the thimble B9 is larger than the other end radial dimension.

Further, the delay block 3 is U-shaped.

Further, the spring 2, the delay block 3 and the ejection column 4 are on the same axis.

Further, the pitch distance is 5mm.

The workflow and principle of the utility model are as follows:

when the product needs to be taken out, the mold opening and ejection actions are started: the ejector pin B9, the ejector pin 4 and other parts move upwards, the delay block 3 and the delay ejector pin 1 do not move at this time, the ejector pin 4 just abuts against the lower surface of the delay block 3 when the moving stroke, namely 5mm, is finished, then as shown in fig. 2, the delay ejector pin 1, the delay block 3 and other parts start to move upwards, and then the ejection and die opening actions are completed.

While the utility model has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
