Hereinafter, a method of manufacturing a molded article in which a resin part and a metal part of the present invention are integrated using the above-described manufacturing apparatus of the present invention will be described.

First, with the mold open as shown in FIG. It is held by the pilot pin 13.

Next, the mold clamping ram is operated to clamp the mold in the range a shown in the graph of FIG. 22 (see Figure 2).

Furthermore, the mold clamping in the range b shown in the graph of FIG. 8 is proceeded. Then, at this time, the fixed side second template 8 is attached to the stepped screw 1.
6 and compression spring 17, the fixed side first
The distance between the template 7 and the template 7 is maintained. Mold clamping proceeds in this state (see Figure 3). At this time, the resin molding machine is in a state where it can generate a pressing force that enables plastic working.

Furthermore, mold clamping is continued in the range C shown in the graph of FIG. Then, the pressing force becomes larger than the spring force of the compression spring 17, the mold clamping progresses, the space between the fixed side first template 7 and the fixed side second template 8 is narrowed, and the bending punch 1
4 is activated. As a result, both ends of the metal member 36 are bent toward the movable platen 18 by the bending punch 14, and a metal part 42 is formed in the molds 7 and 22 of the resin molding machine (see FIG. 4).

When the above-mentioned plastic working is completed and mold clamping is completed, mold clamping force necessary for injection molding is obtained. While the mold is still in this clamped state, molten resin is injected from an injection molding machine (not shown) at high temperature and pressure, and this resin is spun into sprue 5. Runners 10, 11. Via the gate 44, it is filled and supplied into the fixed cavity 12 and the movable cavity 23.

3 is formed, and the metal part 42 of the bracket and the resin part 43 are integrated.

Then, the above-mentioned resin is cooled for a certain period of time to solidify. Once this resin has solidified, the mold is opened. This mold opening is performed in the opposite direction to the above-described mold clamping process until the mold opens as shown in FIG.

Next, when the ejector 26 is activated and the protruding plates 24 and 25 are pushed up, the ejecting pin 27 fixed to the protruding plate 24 slides and the molded product 40 is taken out from the mold. On the other hand, the runner 45 filled with the sprue 5 and the runners 10 and 11 is removed by the operation of the stripper plate 3.

For example, pressurizing a plastic processing tool by clamping (pressurizing) a resin molding machine, setting a metal part into a resin molding machine by setting a metal member into a resin molding machine, and even putting a molded product into a resin molding machine. It is possible to omit processes such as taking out the metal parts from the plastic processing machine by taking them out of the mold, thereby reducing the number of manufacturing steps and shortening the process time. In addition, the minimum equipment required to perform plastic working in the above-mentioned resin molding machine is, for example, a fixed side second mold plate (punch plate) 81, a bending punch 141, a bending die 2461, a stepped screw 16. By simply equipping the resin molding machine with the compression spring 17, it is possible to omit a plastic working machine dedicated to plastic working performed at the same time as resin molding, and the equipment for the plastic working machine becomes unnecessary. Therefore, compared to conventional manufacturing methods in which plastic processing of metal parts in a plastic processing machine and resin molding in a resin molding machine are performed separately, productivity can be improved and equipment costs can be reduced. .

Furthermore, in the manufacturing method of the present invention in the above-described embodiments, the plastic processing of the metal part 42 and the resin molding are performed using the mold clamping pressure means (mold clamping ram) of the resin molding machine, that is, the same pressure means. Therefore, one of the pressurizing means for plastic working can be omitted.

Furthermore, since the plastic working step is simultaneously performed in parallel with the mold clamping step before the mold clamping step is completed, the process time can be further shortened accordingly.

The apparatus for manufacturing a molded product in which a resin part and a metal part are integrated according to the present invention in this embodiment has the above-mentioned configuration.
The molding of the metal part 42 and the plastic working of the metal part 42 can be performed at the same time. Therefore, the above-described manufacturing method of the present invention can be effectively implemented.

Furthermore, in this embodiment, plastic working and resin molding of the metal part 42 can be performed by the mold clamping pressure means (mold clamping ram) of the resin molding machine, that is, by the same pressure means. , one of the pressure means for plastic working can be omitted. However, since the plastic working process can be carried out simultaneously with the mold clamping process before the mold clamping process is completed, the process time can be further shortened accordingly.

In the above embodiment, the plastic working process is started before the mold clamping process is completed, and the latter half of the mold clamping process and the plastic working process are performed simultaneously, but the mold clamping process is completed. After that, the plastic working process may be started, and the latter half of the mold clamping process and the plastic working process may be performed separately.

Hereinafter, a method of manufacturing a molded article in which a resin part and a metal part of the present invention are integrated using the above-described manufacturing apparatus of the present invention will be described.

First, the metal member 70 is held in a mold, and then the mold is clamped and the punch 64 for punching is activated.

Then, the portion of the metal member 72 surrounded by the two U-shaped open lower portions 1 is punched out by the punch 64 and the die 65, and the punched portion of the metal component 66 is punched out.
and the other metal parts 67 are molded. At this time, the metal part 66 of the above-mentioned punched part is sandwiched between the punching bong 64 and the movable template 22,
On the other hand, the other metal parts 67 are sandwiched between the fixed mold plate 7 and the movable mold plate 22, and these two metal parts 66 and 67 are held at different levels with a gap between them. Furthermore, the edges of the two metal parts 66 and 67 that correspond to the edges of the open lower portion 1 of the metal member 70 before processing protrude into the cavities 68 and 69.

Further, in the second invention, the punched part of the metal part and the other part of the metal part, that is, a plurality of metal parts,
It is possible to mold a molded product that is integrally formed through resin parts. Therefore, a plurality of metal parts can be formed in one process, and the process and equipment for molding metal parts can be further omitted.

Furthermore, the third invention is a pressurizing means for mold clamping of a resin molding machine, that is, the same pressurizing means can perform plastic working and resin molding of metal parts, so that one plastic working The pressurizing means can be omitted. In addition, since the plastic working step is simultaneously performed in parallel with the mold clamping step before the mold clamping step is completed, the process time can be further shortened accordingly.

Moreover, in the fourth invention, the resin molding machine can perform molding of resin parts and plastic working of metal parts at the same time. Therefore, the manufacturing method of the first invention described above can be effectively implemented.

Moreover, the fifth invention provides that the metal parts of the punched part and the metal parts of other parts, that is, the plurality of metal parts,
It is possible to mold a molded product that is integrally formed through resin parts. Therefore, the manufacturing method of the second invention described above can be effectively implemented.

Furthermore, the sixth invention is a pressurizing means for mold clamping of a resin molding machine, that is, the same pressurizing means can perform plastic working and resin molding of a metal part. Moreover, the plastic working process can be performed simultaneously and in parallel with the mold clamping process before the mold clamping process is completed. Therefore, the manufacturing method of the third invention described above can be effectively implemented.
