Description

[Detailed description of the invention] [Industrial application field] The present invention provides a mold support that supports the mold with a predetermined distance from the floor when the mold is placed on the floor. Regarding jigs.

[Prior art and its problems] As shown in FIG. 3, conventionally, when a press molding mold 1 is removed from a press machine (not shown) and lowered onto a floor 2 by a crane or the like, the mold If the mold 1 is placed directly on the floor 2, the floor 2 will be damaged, so normally the mold 1 is placed on the sleepers 3.

However, in this case, due to the difficulty in adjusting the position of the suspended mold 1, the worker must hold the sleeper 3 below the mold 1 while suspending the mold 1, as shown in the figure. Since the position of the sleeper 3 had to be adjusted according to the position of the mold 1, there was a problem in that the hanging work was dangerous.

In addition, the sleeper 3 not only had low durability, but also had the problem that pieces of wood that had come off from the sleeper 3 were attached to the mold 1.

[Means for Solving the Problems] The inventor of the present invention proposed that the grooves for attaching to a press machine (for example, 5 in FIG. 3) which are normally provided on the mounting flanges on both sides of the mold (for example, 4 in FIG. 3) ),
We devised a mold support jig that uses this groove as a positioning part.

Specifically, it is a mold support jig that is inserted into a groove formed in a mounting flange of a mold to support the mold, and is mounted in a direction substantially perpendicular to the contact surface with the lower surface of the mounting flange. The elastic member has a stepped through hole that extends through the mounting flange and has an inner diameter one step larger near the lower surface of the mounting flange, and the elastic member supports the mold from the lower side of the mounting flange. a first rigid member having a through hole that is fitted into a large portion; and a first rigid member that is fitted into the through hole of the elastic member on the lower side of the first rigid member and penetrates into the inside that is installed inside the elastic member. a second rigid member having a hole, and a shaft member that is inserted through the through holes of the first rigid member and the second rigid member and has a tip portion that projects above the mounting flange through the groove of the mounting flange. a retaining portion disposed at the tip of the shaft member and engaging the outer peripheral portion of the groove above the mounting flange to prevent the shaft member from coming off from the groove; Between the head formed at the rear end of the shaft member inside the through hole of the second rigid member and the flange that protrudes when the inner wall surface of the through hole of the second rigid member faces toward the shaft member. It is characterized by being equipped with a compressed biasing spring.

[Operations and effects of the invention] As described above, the mold support jig according to the invention has the following features:
The components include an elastic member, first and second rigid members, and a shaft member, and each member has the following functions.

(i) Elastic member...Eases the impact between the mold and the floor when the mold is placed on the floor, and ensures sufficient flexibility between the jig, the mold, and the floor. do.

(ii) (First and second rigid members... serve as core metals for the elastic member, regulate the amount of deflection of the elastic member, and maintain a predetermined distance between the mold and the floor surface.

(iii) Shaft member: Positions the jig relative to the mold by fitting into the groove of the mold.

This mold support jig has the following advantages.

(a) It can be easily attached to the mounting groove from the side of the mold while the mold is being suspended, and after installation it can be lowered together with the mold, allowing extremely safe hanging work.

(a) This jig is smaller than sleepers, lightweight and easy to carry.

(C) This jig has a simple structure and is excellent for mass production.

(d) Since the amount of deflection of the elastic member is regulated by the rigid member, molds of various weights can be accommodated.

(e) Since the mounting groove originally provided in the mold is used as the mounting part, there is no need for any modification on the mold side.

[Example] An embodiment of the present invention will be described below.

As shown in FIG. 1, the mold support jig 6 according to this embodiment has an elastic cylindrical member 7 made of urethane rubber.
The first and second metal rigid cylinder members 8 and 10 (elastic cylinder member 7
(deflection amount regulation and posture holding member) and a collar 1 whose lower end is in contact with the upper surface of the first rigid cylindrical member 8.
1, and a washer 1 that comes into contact with the upper end of the collar 11.
2, biasing spring 13, and both rigid cylindrical members 1
0, 8, a socket bolt 14 that passes through the collar 11 and the washer 12, and a nut 15 that is screwed into the socket bolt 14 on the upper surface side of the washer 12.

To explain in more detail, the elastic cylinder member 7 is
It is an elastic member referred to in the claims column of the utility model registration of this specification, and an upward step 17 is formed in the upper part of the hole 16, and a first rigid cylindrical member is formed in the upward step 17. 8 is abutted from above, and a downward step 18 is formed at the lower part of the hole 16, and an outward flange 20 at the lower end of the second rigid cylindrical member 10 is abutted from below against the downward step 18. There is.

When the mold 1 is not placed, a clearance C ₁ is provided between the rigid cylindrical members 8 and 10, while
A clearance C ₂ is provided between each upper end of the first rigid cylindrical member 8 and the elastic cylindrical member 7 , and a clearance C ₃ is provided between each lower end of the second rigid cylindrical member 10 and the elastic cylindrical member 7 . With these clearances C ₂ and C ₃ ,
The upper end of the first rigid cylindrical member 8 and the second rigid cylindrical member 10
The lower ends of the elastic cylinder member 7 are located inwardly in the vertical direction from the upper and lower ends of the elastic cylindrical member 7, respectively.

The biasing spring 13 is attached to the socket bolt 1
4 and the inward flange 22 at the upper end of the second rigid cylindrical member 10.
0 upward to force the outward flange 20 into pressure contact with the downward step 18, while the socket bolt 14
is biased downward. When the socket bolt 14 is urged downward by the urging spring 13, the washer 12, collar 11, and first rigid cylindrical member 8 are integrally urged downward via the nut 15.
The first rigid cylindrical member 8 is pressed against the upward step portion 17 .

In this way, in this embodiment, the socket bolt 1
The jig 6 can be easily assembled by simply screwing together the jig 4 and the nut 15.

However, when lowering the mold 1 onto the floor 2,
With the mold 1 suspended by a crane or the like, prepare an appropriate number of jigs 6, lift the socket bolt 14 upward together with the washer 12 against the biasing force of the biasing spring 13, and in this state attach the collar 11 to the metal. Type 1
When the spring 1 is fitted into the mounting groove 5 of the
3, the washer 12 comes into contact with the upper surface of the flange 4 around the groove 5, while the elastic cylindrical member 7
comes into contact with the lower surface of the flange 4 around the groove 5, and the jig 6
is attached to mold 1. Thereafter, the mold 1 is finally suspended with the jig 6 attached.

In that case, if the mold 1 is relatively light, the elastic cylindrical member 7 will bend and each clearance C ₁ , C ₂ , C ₃ will decrease slightly, but
Between the rigid cylindrical member 8 and the mold 1 and the second rigid cylindrical member 10
The mold 1 can be supported while leaving a gap between the mold 1 and the floor surface 2.

On the other hand, if the mold 1 is heavy, the clearance C ₁ ,
C ₂ and C ₃ are removed, both rigid cylindrical members 8 and 10 come into contact with each other, and the mold 1 is connected to the first rigid cylindrical member 8.
, the floor surface 2 comes into contact with the second rigid cylindrical member 10 .
However, even in that case, both rigid cylindrical members 8, 1
0, the mold 1 never comes into direct contact with the floor surface 2. In other words, in the above embodiment, the maximum vertical deflection amount C _MAX (=C ₁ +C ₂ +C ₃ ) of the elastic cylinder member 7 is defined by both the rigid cylinder members 8 and 10.
