が製品品質を左右するといった欠点があった。In the conventional multi-mold mold described above, if there is a difference in the volume of the molding material (hereinafter abbreviated as "tablet") introduced for each bot 2, when the resin is completely press-fitted into each cavity 1, The position of the press-fit plunger 5 becomes uneven, making it difficult to obtain good molding results. For this reason, the fourth
It is necessary to absorb this difference by installing a horizontal isobaric machine (10) using hydraulic pressure or the like as shown in the figure in the multi-mold mold or in the press-fitting mechanism. In this equal pressure mechanism, each press-fitting plunger 5 is inserted into an equal pressure function block 10 via a cylinder piston 7, and pressure oil is supplied to the block 10 from a pressure oil inlet 9 to perform this equal pressure function. The pressure oil chambers 7 are connected by an equal pressure oil communication path 11. As a result, each mechanical part becomes complicated, and the product quality is affected by the quality of the isobaric machine tank.
本発明の目的は、これらの欠点を除き、下型のポット間

止金型を提供することにある。The purpose of the present invention is to eliminate these drawbacks, eliminate the need for an isobaric machine tank by providing a resin flow path between the pots of the lower mold, and
The object of the present invention is to provide a resin-sealed mold for multi-molding, which has a simple structure and can improve product quality.

来る。FIGS. 1 and 2 are a plan view of a lower die of a multi-mold mold according to an embodiment of the present invention, and a side view showing a press-fitting mechanism thereof in partial cross section. The basic structure of this embodiment is the same as that of the conventional multi-mold mold, but it is characterized by having a resin flow path 4 between each of the holes. As shown in FIG. 2, the tablets 1 to 1 put into the plurality of pots 2 are press-fitted into the cavity 1 through the resin introduction i\83 by a press-fitting mechanism that does not have an isobaric machine tank. At this time, by absorbing the difference in volume between the tablets using the resin channel 4, the pressure in all cavities 1 can be made uniform and a good molded product can be obtained.

By providing the resin flow path 4 between each pot 2, it is possible to absorb the difference in tablet volume between each pot 2 and obtain a good molding result. Therefore, there is no need to have an additional isobaric machine tank, and the press-fitting mechanism can be simplified, which has the effect of improving product quality.
