Abstract

PURPOSE:To facilitate the inspection and adjustment of machinery by constituting a machine stand of an upper frame, a lower frame and the support frame supporting the upper frame with respect to the lower frame so as to have a rectangular parallelepiped shape and eliminating transverse frames in a left and right direction only from one of the end parts in the front and rear direction of the longitudinal frames in the front and rear direction of the lower frame to form empty space to arrange peripheral machinery in said space. CONSTITUTION:A machine stand 1 is constituted of an upper frame 7, a lower frame 6 and a support frame 8 and formed into a rectangular parallelepiped structure as a whole. The upper frame 7 consists of longitudinal frames 9, 9 juxtaposed in a front and rear direction and transverse frames 10, 10 connected by the frames 9, 9 and the empty space 5 perfectly opened in the front and rear direction is formed at the part where one of the transverse frames 12 is eliminated. A temp. conditioner 17 equipped with casters is pushed in the empty space 5 to be received therein. Therefore, the inspection or adjustment of peripheral machinery such as the temp. conditioner 17 and the alteration of the connection to a main body can be easily performed by drawing out the peripheral machinery from the machine stand.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base of an injection molding machine.

[0002]

2. Description of the Related Art In an injection molding machine, as shown in FIG. 2, a mold clamping unit 2 and an injection unit 3 are usually mounted on a machine base 1 having a frame structure in which mold materials are assembled in a rectangular parallelepiped shape as a whole. The space inside the machine base 1 is used as a housing portion for various components necessary for driving the injection molding machine and a molded product take-out portion. Various components include power panels, control-related equipment, hydraulic and pneumatic equipment.

However, since the electric injection molding machine does not have components such as a pump and an accumulator as compared with the hydraulic injection molding machine, the machine base 1 has a lot of empty space. In a small-sized injection molding machine as shown in FIG. 2, the supporting structure in front of the machine base 1 (on the side of the mold clamping unit 2) is also omitted, and a complete empty space 4 is formed below the front part of the mold clamping unit 2. In a large-sized injection molding machine, as shown in FIG. 3, a frame-shaped machine base 1 is formed up to the front end to support the weight of the mold clamping unit 2 and the injection unit 3. Space 5 is not used for anything.

On the other hand, a peripheral device of the injection molding machine such as a temperature controller, a manual input device with a display device of a separate type, or a resin drying device requires a relatively large space and narrows a working space. Attempts have been made to store these in the above-mentioned empty space in the machine.

However, for example, if the temperature controller is to be stored in the space 5, the weight is as much as 50 kg, and it is difficult to store such a heavy object in the space 5 by overcoming the lower frame 6 of the machine base 1. Requires great difficulty and attention. Also,
In this way, the once-stored liquid circulation hose of the temperature controller must be sewn in a narrow space to be connected to the mold, which requires complicated work every time the mold is replaced. Even in the case of other peripheral devices, there is an inconvenience that the fixing means for the machine base 1 must be released each time the inspection is performed and the device must be taken out of the machine base.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide an injection molding machine capable of easily storing a heavy peripheral device such as a temperature controller in an empty space of the machine base 1.

[0007]

A machine base of an injection molding machine has a rectangular parallelepiped structure including an upper frame, a lower frame, and a support frame supporting the upper frame with respect to the lower frame. The lower frame has a frame structure including a vertical frame in the front-rear direction and a horizontal frame in the left-right direction. However, a horizontal frame is not provided on at least one of the front and rear ends of the lower frame.

[0008]

[Function] The front and rear ends of the lower frame without the horizontal frame have no obstacles that must be overcome when storing the peripheral devices, in other words, are completely opened to the front or the rear. Provides storage space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the front part of an injection molding machine in which a mold clamping unit 2 is mounted on a machine base 1. Other configurations of the injection molding machine are not different from the conventional ones, and thus the description thereof will be omitted.

The machine base 1 is composed of an upper frame 7, a lower frame 6, and a support frame 8 for supporting the upper frame 7 with respect to the lower frame 6, and has a rectangular parallelepiped structure as a whole. The upper frame 7 is, in this embodiment,
This is a frame structure including vertical frames 9 and 9 arranged in parallel in the front-rear direction and horizontal frames 10 and 10 in the left-right direction that are connected to each other.
Like the upper frame 7, the lower frame 6 includes vertical frames 11, 11 arranged in parallel in the front-rear direction, and horizontal frames 12 in the left-right direction that combine these.
It is a frame structure provided with 12. However, the lower frame 6 does not have the horizontal frame 12 at the front end. The upper frame 7 and the lower frame 6 are composed of a plurality of pillar frames 8 arranged on the left and right sides as described above.
Are joined together to form a rectangular parallelepiped frame structure.

Reference numeral 13 is a level adjusting mount, and reference numeral 14 is a door for closing a storage portion formed in the central portion of the machine base 1. That is, in the front part of the machine base 1, there is no horizontal frame 12 in the lower part, and a storage space 15 that is completely open in the front-rear direction is formed.

A temperature controller 17 having casters 16 is pushed into the storage space 15 from the front and stored. When storing, the liquid circulation hose 18 is connected to the mold attached to the mold clamping unit 2 in advance and then pushed in. Reference numeral 19 is an operation and display unit of the temperature controller 17.

The input device with a display device, the resin drying device, and the like are also provided with casters, and can be housed by pushing them after wiring to the main body of the injection molding machine. When inspecting and adjusting the stored peripheral equipment or changing the connection to the main body of the injection molding machine, pull out the peripheral equipment from the machine base.

Even if the horizontal frame 12 is missing at the front and rear ends of the lower frame 6 of the machine base 1, a plurality of other horizontal frames 1 are also provided.
2 connects the left and right vertical frames 11, 11, so that the machine base 1
There is no particular hindrance in terms of strength. If the milling of the upper surface of the machine stand is affected, the horizontal frame 12 of the lower frame 6
The horizontal frame is temporarily welded to the part where the
Alternatively, it is possible to sufficiently deal with the problem by connecting the left and right vertical frames with a jig.

The above is an embodiment. As the lower frame 6 and the upper frame 7 in the machine base 1, not only a combination of a vertical frame and a horizontal frame but also a plate body may be used. In addition, the completely opened storage space 15 may be formed in the rear portion of the machine base 1.

[0016]

The space inside the machine base can be effectively used. It is easy to work because it can be stored in the storage space of the machine base without lifting heavy peripheral devices. It is easy to inspect and adjust the stored peripheral devices and change the connection to the injection molding machine body.
