A conventional vertical injection molding machine will be explained with reference to FIGS. 2 and 3. FIG. 2 is a state diagram showing molding at the first station, and FIG. 3 is a state diagram showing molding at the second station. In the figure, 51 is the first station;
2 is the second station, and each station 51, 5
Each of the lower molds 51a and 52a is placed and fixed on a first slide table 53 and a second slide table 54, respectively. Each of the slide tables 53 and 54 moves along an arrow A (outside) on a slide base 55 formed in an L-shape.
It is arranged to be slidable in the B (inside) direction and the arrow C (outside)-D (inside) direction. Therefore, the lower molds 51a and 52a fixed on each slide table 53 and 54
accesses an injection device (not shown) by alternately moving in direction B or direction D. That is, the first slide table 53 in FIG. 2 and the second slide table 54 in FIG. 3 are placed at the injection molding position.

Note that 57 is a fixed platen, and 58 is a tie bar disposed between the fixed platen 57 and a movable platen (not shown). Further, 59 is a robot that inserts screws, pins, etc. into the mold or takes out the molded product from the mold when the lower molds 51a, 52a move in the A direction or the C direction. The arm portion 60 of the robot 59 can change direction so as to face the second slide table 54 in FIG. 2 and the first slide table 53 in FIG.

It has a plurality of memories that store different molding conditions for each station, and a molding condition output switching means that switches the molding conditions read from each memory according to the station accessing the injection device. The molding condition output switching means outputs the molding condition data read from each memory to the output device.

[0008]

[Operation] According to the present invention, in the molding condition output device of a vertical injection molding machine having a plurality of stations so that a plurality of molds can be used for one injection device as described above, each It has a plurality of memories that store different molding conditions for each station, and a molding condition output switching means that switches the molding conditions read from each of the memories according to the station accessing the injection device,
The molding condition output switching means outputs the molding condition data read from each memory to the output device.

Therefore, when the slide device is operated to alternately select stations and access the injection device, the molding conditions corresponding to each station are read out from the memory and output.
