In addition, since the size of the mold is as large as 2 to 3 m square, it is not possible to determine which position the temperature should be targeted for control for each system.
Furthermore, if each position of the 120 systems is individually control

Embodiment Construction

[0037] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.

[0038] Such as figure 1 As shown, the mold temperature control system 1 of this embodiment controls the temperature of the mold 3 by changing the flow rate of cooling water controlled at a certain flow rate during production in the die-casting machine 2 that produces (casts) aluminum die-casting products. system. The mold 3 constitutes a part of the die casting machine 2 and includes a fixed mold 4 provided in an injection device and a movable mold 5 provided in a mold clamping device.

[0039] Temperature sensors 6 (˜6n) including thermocouples or resistance temperature sensors are attached to various parts of the mold 3 (fixed mold 4 and movable mold 5 ). The temperature sensor 6 detects the highest temperature, the lowest temperature, the average temperature and the current temperature of the mold 3 in the production cycle in real time. The detected temper...

Abstract

Provided is a mold temperature control system capable of reliably performing temperature management even in a large mold having a large number of systems. This mold temperature control system (1) controls the temperature of a mold (3) of a die casting machine (2), and is provided with: a temperature sensor (6) that detects the temperature of each part of the mold (3); a flow rate controller (17) for controlling the instantaneous flow rate of the cooling water at each part of the cooling mold (3); and a control device (7) that acquires the mold temperature detected by the temperature sensor (6), calculates the deviation between the target mold temperature and the current mold temperature for each production cycle, converts the deviation into a flow rate value, and transmits the flow rate value to the flow rate controller (17). And the mold temperature control system (1) is formed so as to vary the flow rate of the cooling water controlled at a certain flow rate within one injection during production.

Description

technical field [0001] The present invention relates to a mold temperature control system for controlling the temperature of a mold of a die casting machine. Background technique [0002] In a die-casting machine for casting aluminum die-casting products, regarding the mold, since molten aluminum enters the center of the mold at every injection, temperature control based on cooling is important. In particular, when the size of the mold becomes larger, unevenness in temperature tends to occur at each location. To eliminate this unevenness in temperature, it is necessary to use an appropriate amount of cooling water at an appropriate location to dissipate heat, and it is necessary to change cooling for each location. water volume. However, since a large mold has many parts, the management method is complicated, and it is difficult to manage it by a conventional method. [0003] If you look at the literature on the management method in the past, there are, for example, the mo...
