Description

[Detailed Description of the Invention] The present invention relates to a positioning device for a mold moving carriage in a press machine.

As shown in Figures 1 and 2, there are two types of positioning pins (a) in the press for the trolley: round and cross-shaped, and they are provided at two diagonal positions on the trolley for positioning in the front-back and left-right directions. was doing.

In presses for forming long products, an excessive thrust force is applied to the positioning pin a due to the difference in deformation between the cart and the bed C during pressurization, causing problems in the strength and life of the positioning pin a.

The present invention was developed in view of the above circumstances, and its purpose is to improve the strength of the locating pin without applying excessive thrust force to the locating pin during press pressurization.
It is an object of the present invention to provide a positioning device for a mold moving cart that does not require much consideration of its lifespan.

Hereinafter, the present invention will be explained with reference to FIG. 6 and subsequent figures.

In the drawing, 1 is a bed and 2 is a trolley.

A positioning pin 4 for regulating the front-rear direction A, which is long in the left-right direction B, is provided in the corner portion 3 at the rear right side of the bed 1, and a positioning pin 4 for regulating the front-rear direction A, which is long in the left-right direction B, is provided in the corner portion 5 at the front left side of the bed 1. A positioning pin 6 for regulating the longitudinal direction A is provided.

In addition, a positioning pin 7 for regulating the horizontal direction B, which is long in the longitudinal direction A, is provided near the center line C at the rear right side of the bed 1.
A positioning pin 8 for regulation in the left-right direction B, which is long in the front-rear direction A, is provided near the center line C at the front left side of the bed 1.

Elongated holes 9 and 10 are provided in the left-right direction B at positions facing the positioning pins 4 and 6 for regulating the front-back direction A on the bed 1 side of the trolley 2. Elongated holes 11 and 12, which are long in the front-rear direction A, are provided at positions facing the positioning pins 7.8.

The positioning pins 4.6 for regulation in the front-rear direction A are inserted into elongated holes 9 and 10 long in the left-right direction B, and the positioning pins 7.8 for regulation in the left-right direction B are inserted in the long holes 11 long in the front-rear direction A. , 12, the force in the longitudinal direction of the truck 1 is stopped by the regulating positioning pins 4 and 6 in the longitudinal direction A, and the force in the left and right direction of the truck 1 is transferred to the regulating positioning pin 7 in the horizontal direction B.
．． Uke stopped at 8.

The regulating positioning pins 4 and 6 are free in the left-right direction B in the long holes 9 and 10, and the regulating positioning pins 7.8 are free in the longitudinal direction in the long holes 11 and 12. When the pressure is applied, the difference in deformation between the bed 1 and the trolley 2 causes the regulating positioning pin 4. 6. 7. 8, no excessive thrust force is applied.

The present invention has been described in detail above, and the positioning pins 4 and 6 for regulating the longitudinal direction A, which are long in the left-right direction B, are provided on the left and right sides of the upper surface of the bed 1. Positioning pins 7 and 8 for regulation in the left-right direction B are provided, and elongated holes 9 and 10 are provided in the trolley 2 into which the positioning pins 4 and 6 for regulation in the front-back direction A are inserted with a margin in the left-right direction. Elongated hole 11.12 into which the regulating positioning pin 7°8 of B is inserted with a margin in the front and back direction.
Because of this, during press pressurization, excessive thrust force does not act on each positioning pin 4, 6° 7.8 due to the deformation difference between bed 1 and trolley 2, and the strength of positioning pins 4, 6, 7.8
There is no longer a need to consider lifespan so much.
