Abstract

PURPOSE:To attain ease of setting of an optimum setting value by providing a magnification setting device so as to optimum the control resolution of an electromagnetic flow rate control valve. CONSTITUTION:The injectin operation of a screw 1 is divided into 1-4 speeds depending on the position by an injection speed controller so as to control each injection speed. A pressure oil is delivered to a chamber 5 of an injection cylinder 4 via the electromagnetic flow rate control valve 2 by the control so as to control the position of the screw 1 via a ram 6. This valve 2 is selected by a command from a controller 7 and its setting is performed by a setting section 8. The setting section 8 is provided with a magnification setting device 12 in addition to an injection speed setting device or the like and has a magnification of, e.g., 1/4 or 1/2. In setting the magnification setting device 12 to 1/2 with said setting device set to 35%, it results in the setting of 17.5% so as to attain a minute numeral setting of a figure being the decimal point or below.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control data setting device that is effective when applied to an injection molding machine.

FIG. 1 is a system diagram of an injection speed control device in a conventional injection molding machine, and FIG. 2 is a front view showing a part of the setting panel in the setting section of FIG. Referring to Fig. 1, the injection operation of the screw 1 can be changed from 1 to 4 depending on the position of the screw 1.
To control each speed separately, pressurized oil from the hydraulic source 3 is supplied to the injection cylinder 40 chamber 5 via the electromagnetic flow control valve 2.
, and the screw I is advanced in the direction of the arrow via the ram 6. The electromagnetic flow control valve 2 is switched by a command from a control device 7. Further, details of the setting section 8 in the control device 7 are shown in FIG. 2. In FIG. 2, 9 is a screw rotation speed setting device, 10 is an injection pressure setting device, and 11 is an injection speed setting device.

Next, the case where the injection speed, injection pressure, screw rotation speed, etc. are digitally set prior to operation of the injection molding machine will be demonstrated using the injection speed as an example.

The usage range of the injection speed is predetermined according to the specifications of the injection molding machine to be used, and can be set in the range of 0 to 99%. Injection speed setting device 1 in Fig. 2
When setting ■ to ■4 in 1, Vll-35% of the maximum value,
VI2 = 80% of maximum value, ■3 - 20% of maximum value, VT
4=will be operated at 10% of maximum value.

Since the setting value resolution in this case is 1/100 (1%), for example, ■3 cannot be set to 17.5%. In this case, it is possible to change the number of digits on the setting device to 3, but
This has the drawback that the device is complicated and expensive, and the operation is also complicated.

The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and includes a control data setting device that displays a percentage of the usage area of a controlled object, and a control data magnification setting that selects the set value resolution of the control data setting device. The purpose is to provide a control data setting device with a simple configuration that is capable of setting fine numerical values below the decimal point. be.

Embodiments of the present invention will be described below with reference to the drawings.
This is a control data setting device to which 2 is added. This magnification setting device 12 has a magnification of 171.1/2 in the embodiment shown in FIG.
．． Three types of 1/3 are provided.

Therefore, for example, the injection speed setting device 11 in FIG.
3 to 17.5% of the maximum value, set the magnification to 1/2.
By selecting and setting the percentage setting in ■3 to 35%, V
I3=35%XI/2=17.5%.

Moreover, if the magnification is selected to be 1/4, the value becomes 8.75%, and it becomes possible to set a fine numerical value below the decimal point. Note that it is also possible to provide a magnification other than that shown in FIG. 3.

The present invention is constructed as described in detail above, and by providing one magnification setting device, it is possible to maximize the control resolution of the electromagnetic flow control valve, and the optimum setting value can be easily set. can.
