Abstract

The invention discloses an opening and drawing device of a circuit board stamping die. The opening and drawing device comprises an upper cross arm assembly arranged above an upper die mounting plate and used for pulling the upper die mounting plate. A lower cross arm assembly for supporting a lower die fixing plate is arranged below the upper cross arm assembly and correspondingly above the upper die mounting plate at the same time. A jack for opening and drawing the die is placed between the upper cross arm assembly and the lower cross arm assembly to implement opening and drawing on the die. According to the opening and drawing device, the portable scissor jack is used as a labor-saving mechanism, heavy dies are easily opened and drawn, and portability and labor saving are realized; and according to more important significance, the die is opened and drawn in a vertical state, a guide pillar and guide sleeve assembly of the die is prevented from being damaged during opening and drawing, and therefore the original precision degree of the die is kept.

Description

technical field

[0001] The invention relates to the field of extracting devices, in particular to an extracting device for a stamping die of a circuit board. Background technique

[0002] Printed circuit board stamping die is a professional precision mold developed with the development of the electronics industry. With the demand for improving production efficiency in downstream factories and technological progress, printed circuit boards have been changed from single-piece production to jigsaw production. The stamping die of this printed circuit board also becomes larger, making the die relatively heavy. When assembling, correcting and maintaining circuit board stamping dies, it is inseparable to open the upper die and lower die. To maintain the precision of the mold, it depends on the precision guide post and guide sleeve assembly of the mold device and its maintenance. The gap between the guide post and the guide sleeve is extremely small, and there is lubricating oil b...
