Abstract

PURPOSE: An automatic temperature controller for a die is provided to keep the uniform temperature in a pipe by proportionally controlling the variable heat capacity of an input part and an output part using a variable motor value. CONSTITUTION: Detected values of detecting parts(7,9) are controlled by controlling variable motor values(3,10). To keep the uniform temperature in a pipe, the detected values of the detecting parts is controlled to be the same by proportionally controlling an inlet part and an outlet part. Therefore, rapid cooling or overheating is prevented. According to precise control of temperature, temperature management of a die becomes easy. Additionally, accumulation of saturated steam in the pipe due to rapid cooling and overheating is avoided.

Description

Mold Temperature Controller {MOLD Automation Controll.}

The present invention relates to an automatic mold temperature control method, and more particularly, to detect the input side and the output shaft calorific value in the detector and operate the variable electric valve to proportionally control the variable calorific value, such as rapid cooling overheating according to the conventional fixed deterministic control method. Solved the problem

In the control method of the variable electric valve by temperature deviation, the input side controls the output side and the output side controls the input side in a variable proportion.

In other words, the value generated in the same or in proportion to the input control temperature value and the exit control temperature value is approached to the mold temperature or the room temperature to be used to keep the amount of heat in a pipeline constant.

1 is a proportional variable electric valve and the detection unit used in the present invention

2 is input side control method

3 is a mold management control method

4 is an output side control method

Hereinafter, described in detail by the accompanying drawings as follows.

Figure 2 is to control the heat amount by detecting the temperature value of the heater tank by the input control method, the low temperature of the sprinkler flows into the mold and quenched, and the value of the detector drops sharply and the difference between the operating temperature value is severe and continues to heat To generate excess steam.

3 is a method of controlling the mold temperature, a value different from the temperature of the media management can be generated. Also, there is a problem in not taking an even distribution of temperature values.

4 is a power control method, the temperature control value between the inlet side and the outlet side is not proportional to each other, and the adjustment range of the heat quantity is too large or too short, the rapid cooling or overheating occurs. In order to solve the problem, as shown in Fig. 1, the detection of (7) and (9) is controlled by controlling the variable electric valves of (3) and (10), and the detection of (7) is performed to maintain a constant temperature in the pipeline. In order to make the value and detection value of (9) equal, the inlet and outlet sides were controlled proportionally.

As described above, the present invention is easy to maintain the temperature control of the mold by controlling the proportional variable to prevent rapid cooling, overheating and fine adjustment.
