Embodiment 1

[0013] Embodiment one: if figure 1 As shown, a movable pop-up device includes a hydraulic jack 1, a lower backing plate 2 is screwed on the jack rod of the jack 1, and a rubber block 3 is arranged on the lower backing plate, and the rubber block The upper end of 3 is provided with an upper backing plate 4, and the upper backing plate is provided with a jacking block 5, and a locking bolt 6 is arranged on the jacking block.

[0014] In this embodiment, in order to reduce weight, the top block is a hollow top block.

[0015] Suppose there are 100 molds. Originally, each mold needs to be equipped with a pop-up device. Now, only about 10 are needed. This device can be moved, and the height and pressure of the ejector block can be adjusted through a jack. As long as the lower template 8 on the machine tool table 7 is provided with a through hole for bolts to pass through, the jack block jacks up the bolts, drives the top plate 9 to rise, and the workpiece is pushed out of the mold...

Description

technical field [0001] The invention relates to a movable pop-top device and a manufacturing method thereof. Background technique [0002] In sheet metal production, pop-up devices are used in the structures of punching dies, bending dies, and stretching dies. Traditionally, pop-up devices have been considered as part of the die structure. This misunderstanding has led to A lot of waste is generated. [0003] In the mass production of a single product, the pop-up device is often used as a part of the mold and designed as a special purpose. However, in mass production or trial production of multiple varieties, a large amount of money can be saved by using a general movable pop-up device. Contents of the invention [0004] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to provide a movable pop-up device and its manufacturing method, which has good ve...
