Field of the Invention The present invention relates to a small-sized injection molding machine which can be moved and installed manually. [0002] The conventional small injection molding machine, even if the injection device and the mold clamping device are downsized, to secure the installation place for the hydraulic pump and the like, the machine base is the injection device and the mold clamping device. Since it is formed larger than the device and the machine base is simply a downsized version of the normal structure, even if everything including the mold is lightened by downsizing, the crane is still used as before. They are being lifted and moving. In addition, the mold temperature controller is separately installed and the mold is heavy enough to be held by hand, so the mold replacement is manual work, but there is no place for placing the mold on the machine stand For this reason, it may be more troublesome than when the mold is changed using the device. The present invention has been conceived in order to solve the above-mentioned problems in a small injection molding machine, and an object thereof is to form a machine base by a box-shaped body having a rectangular planar shape and a tall shape. By using the inside of the machine and the upper surface of the machine, the injection molding machine is compacted, the upper surface of the machine is used as a work table, and the caster adopts a new compact size that can be moved manually. An object of the present invention is to provide an injection molding machine. According to the present invention for the above object, a machine base is formed by a tall box having a rectangular planar shape and a caster and a stand are attached to the bottom of the box. The machine stand can be moved and installed manually, and various devices and equipment necessary for injection and mold clamping, mold temperature controller, etc. are stored inside the machine stand, and the machine is injected on the opposite side of the upper surface of the machine. The device and the mold clamping device are arranged side by side in a longitudinal direction, and the operation side on the top of the machine base is formed on a work table. [0005] In such a configuration, all the devices and equipment as an injection molding machine are collectively provided on a machine that can be moved by casters. Therefore, the installation place only needs to secure the installation space of the machine. There is no need to separately install a mold temperature controller as in conventional small injection molding machines,
It requires simplicity that can be easily moved. In addition, the space secured on the operation side of the upper surface of the machine allows the upper surface of the machine to be conveniently used as a work table for mold replacement and maintenance. FIG. 1 shows a hydraulic molding machine as an example. 1 is a machine base, 2 is an injection device installed on the upper surface of the machine base, 3 is a mold clamping device, and both are mold clamping devices. Are covered by a cover 4. The injection device 2 has a screw diameter 14 in the heating cylinder.
mm and an injection capacity of about 6.2 cubic centimeters per shot. Further, the mold clamping device 3 is a small one having both a mold clamping stroke and a minimum mold thickness of 110 mm and a tie bar interval of about 102 mm. The machine 1 has a length of 1425 mm and a height of 11
The plane shape of about 00 mm and the width of about 490 mm is made of a rectangular and tall box, and the casters 5 are attached to the four corners of the bottom of the box together with the stand member 6. It has to double. [0008] As shown in FIG.
A mold cooling means such as a chiller unit cooler 9, a water tank 10, and a cooling water pump 11, and a mold temperature controller 12, which is vertically divided by a partition plate 7 on a floor plate 8 below the partition plate 7. The power cord reel 13 and the like are stored. Above the partition plate 7, a hydraulic pump 14 and an oil tank 15, and a hydraulic drive means such as a valve device 16 of a hydraulic circuit connecting them are accommodated. Storage room 1 (not shown)
8 are sectioned. The injection device 2 and the mold clamping device 3 are installed in the longitudinal direction so as to be shifted toward the non-operating side of the upper surface of the machine base. A table 19 is formed. On a partition plate below the mold closing position of the mold clamping device 3, a shooter 20 of a molded product opened at the front plate 1a of the machine base 1 is provided.
A pusher 21 is attached to the upper side of the side of the injection device. Reference numeral 22 denotes a viewing window of the water meter of the chiller unit cooler 9, reference numeral 23 denotes a switch installation portion, reference numeral 24 denotes a hopper, and reference numeral 25 denotes a controller monitor. In the small-sized injection molding machine having such a configuration, a female worker who is less powerful than a male worker can be easily transferred by holding the pusher 21 with his / her hand and pushing. Can be easily installed at a predetermined place. In addition, since all the devices and equipment necessary for injection molding are installed in the machine base 1, the installation space is sufficient in the installation space of the machine base 1, and since all the driving of the molding machine is performed in the machine base, And the operating side on the upper surface of the machine
Since 9 is set, a jig, a mold, and the like are placed on the work table 19, and operations such as maintenance and mold replacement can be easily performed. Although the above embodiment is an example of a hydraulic injection molding machine, even in the case of an electric injection molding machine,
Since the electric motor and the like necessary for driving the injection device and the mold clamping device can be housed in the upper part of the machine base 1 instead of the hydraulic pump 14 and the oil tank 15, the present invention is directed to a small hydraulic type injection molding machine as shown in the figure. However, the present invention is not limited to this.
