昭６３−６７４５５号に記載されている。2. Description of the Related Art A pair of die sets (sub mold clamping mechanism) having mold opening / closing means at the top and bottom, guide means for moving the die sets laterally, and both of the sub mold clamping mechanisms are at stop positions. The vertical main mold clamping mechanism arranged in the central part, moving means for moving both sub mold clamping devices to alternately move the sub mold clamping mechanism into and out of the main mold clamping mechanism, and vertically in the die set. An alternating injection molding machine consisting of two sets of dies which are divided and attached is described in Japanese Patent Publication No. 63-67455.

りなる。The vertical type main mold clamping mechanism provided in this conventional one is provided with a mold clamping cylinder on an upper plate which is connected by a tie bar and is located above, and a movable plate which guides the tie bar by the mold clamping cylinder. It is configured to pressurize and clamp the die fed together with the die set between the movable platen and the lower platen.

間に介在した案内手段及び移動手段に作用し、長期にわ
たる使用では反復して受ける型締力により案内手段及び
移動手段が損傷し易いことである。One of the problems in such a case is that the mold clamping force acts on the guide means and the moving means interposed between the lower die mounting plate and the lower board of the die set, and the mold clamping force is prolonged. In use, the guide means and the moving means are easily damaged by the mold clamping force repeatedly received.

る。Further, since the mold clamping cylinder having a load is located above, there is a problem in the stability of the molding machine. Further, the injection device is laterally arranged on the side of the vertical main mold clamping mechanism. Due to this, the ejection force acts at a right angle to the clamping force in the vertical direction, so a larger clamping force is required than when the ejection force is opposed to the clamping force, and as a result, it is adopted there. The main mold clamping mechanism of 1 also has a problem that it tends to be large.

にある。The present invention was conceived in order to solve the above-mentioned conventional problems, and its purpose is to lower the mold clamping direction of the main mold clamping mechanism from the lower side to the upper side and vice versa. The main mold clamping mechanism is configured so that the influence of the mold clamping force on the guide means and the moving means can be reduced, and the stability and the simplification of the molding machine can be improved.

ある。According to the features of the present invention according to the above object, an upper pressure receiving plate above the machine base and a lower pressure receiving plate inside the machine base are integrally connected by a tie bar fixed to the machine base, and the lower portion thereof is connected. A main mold clamping mechanism is configured by providing a mold clamping ram on the pressure receiving plate.
The upper pressure receiving plate is provided with the injection device facing downward.

The upper die mounting plate contacts the upper pressure receiving plate of the main die clamping mechanism, and strong die clamping of the die occurs there. In addition, since the injection pressure acts vertically from above with respect to the upward mold clamping force, the mold clamping force can be smaller than when the ejection force acts at right angles to the vertical mold clamping force. It will be.

A plurality of tie bars 32, 32, which are inserted and fixed, are integrally coupled to each other, and a mold clamping cylinder having a mold clamping ram 33 is provided in the central portion of the lower pressure receiving plate 31 thereof.

6, the mold 11 is divided and attached, and one of the molds 11 is sent into the main mold clamping mechanism 3 together with the sub mold clamping mechanism 1B by the driving means, and the sub mold clamping mechanism 33 is driven by the mold clamping ram 33. After the mold 11 is clamped together with 1B, the injection device 4 is lowered and the nozzle is touched, so that the resin can be injected into the mold 11.

く済むようになる。The pressure generated by the mold clamping ram 33 is first transmitted to the lower mold mounting plate 12 via the mold clamping ram abutment portion 19 which is in contact with the mold clamping ram 33 due to the rise, whereby the mold 1
4, the sub mold clamping mechanism 1B rises as shown in FIG. 4, and the upper mold mounting plate 16 moves the upper mold pressure plate 30 of the main mold clamping mechanism 3.
And the mold is strongly clamped there. Further, in this case, since the injection pressure acts perpendicularly on the upward mold clamping force, the mold clamping force exerts the ejection force at a right angle to the vertical mold clamping force. It will be smaller than the case.

なる。When the gate seal after injection is completed,
When the injection device 4 is pulled up and the upper mold mounting plate 16 is maintained in the mold clamping state by the hydraulic cylinder 13 of the sub mold clamping mechanism 1B, the mold clamping ram 33 is returned to its original position to remove the mold clamping force. Since the mechanism 1B can move on the base plate 21, when the electric motor 22 is rotated in the reverse direction, the feed piece member 25 moves so that the sub mold clamping mechanism 1B goes out of the main mold clamping mechanism 3 and instead the adjacent mold clamping mechanism 3 moves. The sub mold clamping mechanism 1A is fed into the main mold clamping mechanism 3.

The mold is opened by the hydraulic cylinder 13 and the molded product is taken out. After the molded product is taken out, the sub mold clamping mechanism 1B is clamped again for the next injection molding.

を圧縮する。Although the above steps are for ordinary injection molding, injection compression molding can also be performed. In this case, first, the gap between the upper pressure receiving plate 30 and the upper die mounting plate 16 is adjusted so as to serve as a compression allowance, and after being sent to the main die clamping mechanism 3, the upper die attaching plate 16 is moved by the hydraulic cylinder 13. The mold is opened until it hits the upper pressure receiving plate 30 to expand the cavity volume in the mold. In this state, after the resin is injected and filled from the injection device 4 into the mold, the mold opening by the hydraulic cylinder 13 is used as the mold clamping. At the same time as switching, the mold clamping force of the main mold clamping mechanism 3 is increased to reduce the cavity volume and compress the resin in the cavity.

As means for this, the hydraulic cylinder 13 and the cylinder of the mold clamping ram 33 are sequentially released or the main pressure is released. It is possible to employ a method in which the mold clamping force is controlled by the hydraulic cylinder 13 after being fed from the mold clamping mechanism 3.

Since positioning can be performed by providing a stopper or controlling the movement position, the present invention is not limited to the positioning described in the embodiment.

The tie bar 32 fixed to the machine base 2 is integrally connected, and the lower pressure receiving plate 31 is provided with the mold clamping ram 33 to configure the main mold clamping mechanism 3 in the alternating injection molding machine, and the upper pressure receiving plate 30 is provided with the injection device 4.

堅牢にする必要がない。Since the sub mold clamping mechanism is pressed against the upper pressure receiving plate fixed above the machine base by the mold clamping ram of the lower pressure receiving plate to perform strong mold clamping of the mold, the mold clamping force is the same as that of the sub mold clamping mechanism. It does not act on the moving means, the guide member, etc. Therefore, it is not necessary to make the moving means, the guide member, etc. particularly robust, unlike the conventional alternating injection molding machines.

て簡素化することができる。Since the mold clamping force is applied upward with respect to the downward ejection force, the mold clamping force is smaller than that when the ejection force acts at right angles to the mold clamping direction. Therefore, the main mold clamping mechanism can be downsized, and the rigidity can be reduced to simplify the structure.

Since the upper pressure receiving plate is equipped with an injection device that is lighter than the mold clamping ram, etc., the stability of the molding machine is improved compared to the conventional one, and the tie bar etc. can be rigid enough to withstand those loads, so there is also a mounting space. The molding machine can be compactly integrated and downsized as a whole without requiring a wide space, and the installation area of the molding machine can be small because the injection device is vertically accommodated in the machine base.
