Description

[Detailed description of the invention] When pressing a large number of products by arranging male and female molds in multiple rows at the bottom of the press, the upper pressing plate can be pressed using a conventional pressing device. In a device that presses the pressed product by pressing the workpieces sequentially at different times on a bed at the bottom of the lower part, the molds are piled up and pressed one after another from the bottom, so there is a difference in the pressing time. In particular, when compacting is performed using a hot press, differences occur in the compacting time and press temperature, resulting in differences in processing conditions, resulting in various inhomogeneous products, which causes inconvenience.

However, the multi-stage molding press machine equipped with the simultaneous pressing device of the present invention is equipped so that the pressing process using the mold of the molding technique can be performed simultaneously under the same conditions. However, it is possible to efficiently press and tighten simultaneously using multiple rows of molds, and it also makes it possible to process excellent products by making them all uniform.

Now, the structure, purpose and effect of the multi-stage forming press equipped with the simultaneous pressing device of the present invention will be explained in detail with reference to the drawings as follows.

This invention is applied to a molding press machine, as shown in Figs. 1, 2, and 3, a cylinder bed 2 and a lower bed 1 are equipped with lowering equipment for a hydraulic or pneumatic cylinder 3 at the upper part.
The mold 15 is inserted and installed between the pressure plate 4 and the intermediate plates 5, 5, arranged in multiple rows (Fig. 5).
Each rack 12, 12', 13, 13', 14 was installed in multiple rows at two locations, front and rear, on both the left and right sides of...
・14', ......, on the shaft 7 installed at the bottom thereof, with the same module pitch as each rack (Fig. 7), with the number of teeth in the ratio of 3:2:1. By engaging the pinnons 8, 8', 9, 9', and 10, 10' so that the ratio of the teeth is 3:2:1, The same effect can be achieved by setting .

Each rack 12/12', 13/13', 14/14
' and each pinion 8, 8', 9, 9', 10, 10' engage, pressure plate 4 and each intermediate plate 5, 5,...
... are lowered at different speeds, in this case at a ratio of 3:2:1 (Fig. 4). It works as well as it can.

Thus, if the multi-stage molding press of the present invention is used, as shown in FIG. Since they are pressed at the same time and processed under the same conditions, it is possible to efficiently produce high-quality products (Figure 6).
