Abstract

A moulding machine for bricks or the like, wherein moulding is accomplished by filling raw material for the bricks in a mould (1) and moulding the material between upper and lower plungers (2, 3) applied with pressure. A mould base (4) has aU-shaped configuration opened at its front side. The moulding machine is so assembled that when the mould (1) is raised, its cross section taken through a collar will not interfere with the cross section of the mould base (4), whereby the mold (1) and the upper and lower plungers (2, 3) are assembled. The assembly is free to telescope through the opening of the base (4). Thus, the moulding machine allows mould exchange to be effected more rapidly and more accurately than with the conventional moulding machine.

Description

Specification

Title of invention ''

Brick which molding machine

The present invention is a proposal of a new technique for improving the work efficiency of a molding machine such as a brick, in order to reduce an excessively large amount of time associated with mold replacement, which has been conventionally performed,

Background art

In Fig. 1, Fig. 2 and Fig. 2, 1 is a mold, 2 and 3 are upper and lower plungers, 4 is a mold stand], and it is attached to the side column of frame 6. The left and right hydraulic cylinders 5 move to the mold stand 4, and the upper hydraulic cylinder 9 moves to the upper banger 2 via the lower bushing block 8. The brick material put into the mold 1 is pressed and formed between the descending upper lance 2 and the fixed lower lance 8. Same as previously known ones ·

There is a hole 13 on the lower surface of the mold base 4], and the downward projecting bin 12 of the mold 1 is fitted to this to determine the mounting position. Therefore, in the example of FIG. Before and after the mold stand 4, a wedge 11 that moves forward and backward by the hydraulic cylinder 10 is mounted in a narrow position, and the wedge 11 moves forward.)) Press it to mold stand 4 and fix it. .

In these conventional brick molding machines, it is necessary to replace the mold 上部 Upper Blunger 2 and-Lower Blunger 3 every time the size and shape of the forming bricks change, and replace them During this period, it is impossible to perform brick forming, of course, so using a conventional box-shaped mold stand would require a large amount of time for replacement and reduce the operating rate of the molding machine. Managare no Kata ·

Disclosure of the invention

The invention of the present application is a mold 1 combined with a fixed size that has been turned away from such extremely low efficiency habits.

It focuses on the idea of a trick that attempts to omit this wasted time by allowing two or three to enter and exit the mold stand 4 quickly. '

The best form to carry out the investigation OMPI In other words, in the present invention, the mold table 4 is formed as a U-shaped open front as shown in FIG. It is important that the pair of the jar 2 and the lower bunger 3 can be freely moved into and out of the mold assembly 4 from this open part. In the position shown in the figure, the new flanged surface of the mold 1 rises above the mold stand 4, and the upper and lower plungers 2, 8 above and below the center of the mold 1, along the movable carriage 16, and at right angles to the plane of the paper. It is assumed that the flange can come into close contact with the bottom of the mold when the mold stand rises.

On the other hand, as shown in FIGS. 1 and 2, the movable Taifu 16 on which the mold 1 is placed has an upwardly projecting bin 15. It is positioned and has a roller 17 at the lower end, which shall move back and forth on the movable rail 19 and the fixed rail 7 in a forward and backward manner. Also, as shown in Fig. 5, a U-shape with an open front is used to prevent interference by the lower banger 8

According to the above structure, the newly exchanged mold 1 and the upper and lower bangers 2 and 3 are mounted on the mold moving carriage 16 and the front open U-shaped mold stand 4 is mounted. Move to the upper center of the mold stand 4 and the end point of the moving carriage 16 is stopped by the stopper 18 attached to the fixed rail. 1? Stop exactly at the center position. ·

Subsequently, the mold base 4 is raised by the hydraulic cylinder 5 which moves the mold table 4 upward and downward, and the flange surface of the mold 1 is formed with the projection bin 12 and the hole 18.

, RE O PI WIPO Guided to the bottom of the mold stand 4 at the correct position. · If the ascent continues further, the mold 1 and the upper and lower blazers 2 and 3 will be dismantled. As shown in the figure, the mold carrier 16 moves to the left and exits outside the press area.

The mold 1 on the mold stand 4 is moved forward by the hydraulic cylinder 10 and the wedge 11]). The mold 1 is crimped to the mold stand 4, and then the mold stand 4 is lifted up. Move the plunger 2 to the plunger block 8, and lower the mold base so that the lower plunger 3 comes into contact with the lower frame of the frame 6. Fix the plunger 3 at the bottom of the frame 6 with a bolt or the like.]? Fix each, and complete the installation work. Take out the mold 1 before use outside the press. working the reverse of the work is the same quick箇単this and ¾ physician But until jar is to be carried out in the upper Symbol mounting work _β

Industrial applicability

It is not easy to move the mold 1 and the upper and lower plungers 2 and 3 separately, avoiding interference of the main body of the brass, and to fix them accurately at the predetermined positions. It is difficult for many people to imagine, but according to Honmei

1. The mold and upper and lower bangers are outside the press

It must be combined at a precise center position in advance.

2. Being in the center of the breath, the positioning is automatically and accurately performed.

3. Vault OMPI to the frame of the upper and lower banger The installation work is easy.

What are the advantages? However, I am convinced that the real benefits of brick molding and similar industries are groundbreaking.]?

Claims

The scope of the claims

A mold, such as a brick, is placed inside and the upper and lower plungers are pressed. During this process, the mold is pressed and supported on a vertically movable mold table. The base was formed in a U-shape with one opening, and the upper and lower bungers fitted in the mold were inserted through the opening to the center of the mold so that they could enter and exit. A brick molding machine that specializes in this.
