Abstract

<P>PROBLEM TO BE SOLVED: To provide a mold in which an aggregate is hard to flow into the under side of a horizontal line bar which can solve the problem that the density of the aggregate becomes lower, and can manufacture a concrete block with a horizontal line having a favorable split skin in the mold for producing the horizontal line for the purpose of a decoration on the molded concrete block. <P>SOLUTION: The horizontal line bar 9 is positioned at a position higher than a specified position, and the aggregate is made to flow into the mold, and pressure is applied to the aggregate top surface by an upper mold press. At the same time, the horizontal line bar 9 is moved downward, and the aggregate under the horizontal line bar is compressed, molding is performed in such a manner that the density of the aggregate may become the same on the top and the bottom of the horizontal line bar. In the vertical movement of the horizontal line bar, the inlet side and the outlet side of the line bar are simultaneously moved, and the put-in/takeout out of the horizontal line bar is smoothly performed. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

Industrial application fields

The present invention relates to a mold for manufacturing a concrete block.

The makeup surface of the conventional concrete block was mainly the split skin with the whole surface, the split skin with the vertical line, or the concrete block with only the vertical line.

Problems to be solved by the invention

The original decorative block decorative line is only a vertical line. The present invention is a molding form for the purpose of creating a horizontal line. The biggest neck that manufactures the block of the horizontal line is that the aggregate does not flow into the underside of the line bar and is difficult to make because of the low density of the aggregate.
If the density of the aggregate is low, the surface of the split skin will be deformed when processed into split skin and a good quality product will not be produced.

Means for solving the problem

In order to achieve the above object, a structure is adopted in which the horizontal line rod of the forming mold can be moved up and down.

Action

As shown above, in the production of a decorative block with a horizontal line, it is impossible to produce a good product unless the aggregate density on the upper and lower sides of the horizontal line bar is uniform. In order to reduce the density of the steel sheet and prevent its drawbacks, the molded line material flows in with the horizontal line rod positioned above a predetermined position. After the aggregate has sufficiently flowed in, if pressure is applied to the upper surface of the aggregate with the upper die press, the horizontal line bar is moved downward and the lower part of the horizontal line bar is compressed to form the aggregate with the same density. Good products can be made.
The horizontal line bar can be moved up and down smoothly by moving the entrance and the receiving port of the line bar at the same time.

The mold of the present invention is provided with cylinders “5” for moving the horizontal line bar up and down before and after the mold. The horizontal line bar “9” is moved in the direction of the arrow “10” and is inserted into the road entrance “6” and the receiving port “7” and fixed.
Before putting the aggregate into the formwork, as shown in FIG. 2, the horizontal line bar “9” is raised upward in the direction of the arrow “11”, and the aggregate is thrown in.
Even if the aggregate is sufficiently charged, the aggregate is thin and the density of the aggregate is low, and a good product cannot be produced. In order to equalize the density of the aggregate, as shown in FIG. 5, the horizontal line rod is moved downward by “11” to eliminate the portion D and press the entire upper surface with the upper press part of “4”. To move the horizontal line bar downward, use the cylinder “5” to keep the horizontal line barway entrance “6” fixed to the piston and the receiving port “7” horizontally. Moving.
The upper die 4 that moves the horizontal line rod in the direction of the arrow shown in FIG. 6 after the whole is sufficiently vibrated and compressed is further lowered to move the upper die press part of the upper die 4 to the lower part of the lower mold frame. The receiving plate 12 is also lowered. As shown in "Fig. 7", the molded product is removed to make one cycle.

The invention's effect

As described above, since the present invention can continuously produce a decorative block with a horizontal line, it can provide products to the market at a low unit price.
In addition, if a block with a horizontal line is provided to the market, it can be combined in various ways at the time of implementation, and it will be a great force for market expansion because it will meet the needs of consumers.
