DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an injection molding machine having an optional box for collectively storing members other than the standard equipment, particularly additional electric components and hydraulic units.

[0002]

2. Description of the Related Art In an injection molding machine 1 (FIG. 4), power and control electric members are arranged inside a base frame 4 on which an injection unit 2 and a mold clamping unit 3 are mounted. In the so-called horizontal injection molding machine 1 in which the injection unit 2 and the mold clamping unit 3 are arranged on the base frame 4 so as to face each other, the inside of the base frame immediately below the injection unit is defined as a space 5 for the electrical component, and The inside of the frame is a space 6 for taking out a molded product.

[0003] On the other hand, the injection molding machine 1 is equipped with peripheral equipment such as a robot for removing a molded product or exchanging a mold, a mold temperature controller or a resin dryer as required. In addition, it is often convenient to equip the injection molding machine 1 with electrical components for control and a hydraulic unit.
For this reason, a box for accommodating electrical components and hydraulic units for peripheral equipment may be added to the injection molding machine 1 as an option according to the customer's order or as an option (an additional option box 7). In this case, the option box 7 is arranged on the back panel (FIG. 4) on the non-operation side of the injection molding machine or inside the base frame immediately below the mold clamping unit so as not to hinder the operation of the injection molding machine by the operator ( (Fig. 5).

However, the option box 7 mounted on the back panel may protrude outward to increase the required installation area as an injection molding machine and interfere with other equipment. Further, since the rear panel can be basically opened and closed by a hinge, the cable from the option box 7 attached to the rear panel also needs to be attached in a movable state, and wiring is troublesome. Furthermore, if the option box 7 is arranged inside the base plate on the mold clamping unit 3 side, this may hinder the removal of the molded product. On the other hand, peripheral devices of the injection molding machine 1 are often arranged at the center of the injection molding machine 1.

[0005]

SUMMARY OF THE INVENTION According to the present invention, the option box can be arranged at a position convenient for connection with peripheral devices without obstructing or increasing the installation area. The task is to provide an injection molding machine.

[0006]

The present invention relates to an injection molding machine in which an injection unit and a mold clamping unit are arranged on a base frame so as to face each other. Injection unit side base frame inside the bottom of the injection unit to provide space and option box additional space for electrical equipment section. The optional box contains power for peripheral devices and
The control electrical components are stored. The space for the expansion of the option box will be on the mold clamping unit side with respect to the space for the electrical unit. The option box may be arranged on the back side of the injection molding machine in the option box additional space.

[0007]

[Action] can be arranged option box to the base frame inside the bottom of the injection unit by a configuration in which a electrical part space and option box additional space inside the base frame beneath the injection unit. The option box can be arranged at the center of the injection molding machine by setting the space for adding an option box on the mold clamping unit side with respect to the space for the electrical unit. By arranging the option box on the back side of the injection molding machine in the option box extension space, the front side of the option box extension space can be effectively used.

[0008]

FIG. 1 shows an injection molding machine 1 having an injection unit 2.
And the mold clamping unit 3 are provided on the base frame 4 so as to face each other. In addition, a resin dryer, a mold temperature controller, a product take-out robot, and the like (not shown) can be employed as peripheral devices. Base frame 4
Is a space under the injection unit 2, a space 5 for an electrical component and a space 8 for adding an option box are provided immediately below the injection unit 2, and a portion directly below the mold clamping unit 3 is a molded product removal space 6. . Inside the base frame immediately below the injection unit 2, the option box extension space 8 is provided on the mold clamping unit 3 side with respect to the electrical component space 5, and is located at the center of the injection molding machine 1 (the center in the longitudinal direction of the base frame).
positioned.

In the electrical component space 5, power and control electrical components 9 (input unit, I / O board, control unit, power unit, various servo units, etc.) for driving and controlling the injection molding machine 1 are provided. It is stored (FIG. 2). The option box 7 is disposed on the back side of the option box extension space 8 via a mounting board 10. The mounting substrate 10 is a sheet metal processed product and is a base frame
The option box 7 is attached so as not to protrude from the back of the injection molding machine 1. The option box 7 contains additional equipment such as a 200 V outlet required for a resin dryer and a mold temperature controller, a 100 V outlet required for a molded product removing robot, and a hydraulic unit for a mold changing machine. Reference numeral 11 denotes a cable, which connects the additional equipment in the option box 7 and the electrical component 9 of the injection molding machine 1 so that the operation of a product removal robot or the like is controlled by the injection molding machine 1. Reference numeral 12 denotes a hole for taking out a cable.
0 is formed.

According to this configuration, the option box 7 is mounted so as to be fitted into the inner space of the base frame 4 and does not project to the rear side. In addition, the injection molding machine 1
Is provided with the peripheral equipment, it is connected to the injection molding machine 1 via the additional equipment of the option box 7, but in this case, the option box 7 is located substantially at the center in the longitudinal direction of the injection molding machine 1. Therefore, the distance between the peripheral device and the option box 7 is short, and the wiring of cables and the like connecting them is short. Also, the cable is long and does not get entangled.

Since the option box 7 does not need to be so large, if it is mounted on the rear side of the option box additional space 8, a space is created on the front side, and consumables such as fuses, air filters, band heaters, etc. are removed. It can be used as a place to store. The above is an example, and the present invention is not limited to the illustrated specific configuration. The option box may be mounted on the front side of the option box additional space 8. How to install the option box is not limited,
The mounting board 10 may not be used.

[0012]

According to the present invention, a space for mounting an option box is provided inside the base frame below the injection unit , so that the option box can be easily mounted on the injection unit and does not protrude from the side or back of the injection molding machine. . Since the option box is located at the center in the longitudinal direction of the injection molding machine, the cables to peripheral devices are short and economical, and can be wired neatly. The base frame inside the bottom of the mold clamping unit can be a dedicated extraction product.
