Abstract

(57) [Abstract] [Purpose] To provide a match plate device in which the match plate body on the master plate can be replaced with one touch. [Structure] A frame-shaped support member 3 is provided on an upper surface of a master plate 1 having a through hole 2 penetrating vertically and each of the through holes 2 and 4 is formed.
Are concentrically fixed to each other, and a plurality of stepped holes 6 oriented in the horizontal direction and having a small tip end located inside the supporting member 3 are provided at appropriate intervals. A steel ball 7 is disposed on the tip end side of the stepped hole 6 so as to partially project from the support member 3, and the steel ball 7 is placed inside the stepped hole 6 of the stepped hole 6. A match in which a compression coil spring 8 for urging to the tip side is provided, and a recess 12 is formed at a position inside the support member 3 of the master plate 1 that can be inserted into the support member 3 and faces the steel ball 7. The plate body 11 is detachably mounted by pressing the steel ball 7 against the surface of the recess 12.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an improvement of a match plate device for a mold making machine.

[0002]

[Prior art and problems]

 In the conventional match plate apparatus, the match plate body is generally fixed on the master plate with a large number of bolts, so that in order to replace the match plate body on the master plate, a large number of bolts must be removed and installed. However, the replacement of the match plate body was very troublesome and time-consuming. The present invention has been made to solve the above problems, and an object thereof is to provide a match plate device in which the match plate body on the master plate can be replaced with one touch.

[0003]

[Means for Solving the Problems]

 In order to achieve the above object, the match plate device of the present invention has a frame-shaped support member fixed to the upper surface of a master plate having through holes penetrating vertically and concentric with each through hole. Has a stepped hole with a small diameter at the tip end that is oriented horizontally and is located inside the supporting member. The stepped hole has a steel ball on the tip side inside the stepped hole. Is provided so as to project from the support member, and a compression coil spring for urging the steel ball toward the tip side of the stepped hole is provided in the stepped hole, and the compression coil spring is provided at the position inside the support member of the master plate. Is characterized in that a match plate body which is insertable into a supporting member and has a recess formed at a position facing the steel ball is detachably mounted by pressing the steel ball against the surface of the recess.

[0004]

[Action]

 In such a structure, the body of the match plate placed on the master plate is fixed by a steel ball urged by a compression coil spring. Also, when the match plate body is pushed up from above the master plate, the steel ball is pushed outward of the support member against the repulsive force of the compression coil spring, and as a result, the fixed state of the match plate body to the master plate is released. It will be.

[0005]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. 1. The master plate 1 has a rectangular plate shape, and a rectangular through hole 2 vertically penetrating the central portion thereof. Further, on the master plate 1, a frame-shaped support member 3 is fixed with hexagon socket head bolts 5 and 5 with its through hole 4 concentric with the through hole 2. The supporting member 3 is provided with a plurality of stepped holes 6 oriented in the horizontal direction and having a small tip portion located inside the supporting member 3 at appropriate intervals. A steel ball 7 is disposed on the tip end side in 6 so as to partially project from the support member 3. In addition, a compression coil spring 8 for urging the steel ball 7 toward the tip side of the stepped hole 6 is arranged in the stepped hole 6, and the other end of the compression coil spring 8 has a stepped hole. It is pressed by a plug 9 screwed to the other end of 6. Further, a positioning pin 10 oriented vertically is provided upright inside the above-mentioned supporting member 3 on the master plate 1, and a match plate body 11 is positioned and placed on the positioning pin 10. The match plate body 11 is insertable into the support member 3 and is fixed by pressing the steel ball 7 on the surface of a recess 12 formed on the side surface.

With such a structure, when the match plate body 11 is inserted into the supporting member 3 and placed on the master plate 1, the match plate body 11 is urged by the compression coil spring 8 to be urged by steel. It is fixed by the ball 7. Further, when the match plate body 11 is pushed up from above the master plate 1, the steel balls 7 are pushed outward of the support member 3 by the match plate body 11, and as a result, the match plate body 11 is moved to the master plate 1. The fixed state of is solved.

[0007]

[Effect of the device]

 As is clear from the above description, according to the present invention, the match plate body can be fixed on the master plate simply by placing the match plate body on the master plate, and the match plate body can be pushed up from the master plate. , The match plate itself can be released from the master plate, which has excellent practical effects.
