Embodiment 1

[0031] Such as figure 1 As shown, the heating and cooling system of the metal mold involved in the present embodiment 1 includes: the metal mold 1 and the metal mold 2 of the A molding machine 8a and the metal mold 3 and the metal mold of the B molding machine 8b for molding raw materials such as molding resins. The mold 4 is switched to supply steam or warm water as the heating medium, and the temperature adjustment device 10 as the cooling water of the cooling medium; the steam heating unit 30 that sends steam to the temperature adjustment device 10; the warm water that sends warm water to the temperature adjustment device 10 The heating unit 35; the cooling unit 40 that circulates the cooling water; and according to the control of the temperature regulating device 10, the above-mentioned metal mold 1, metal mold 2, metal mold 3, and metal mold 4 are vacuumized, rapidly expanded, and blown, etc., And put into the above-mentioned two molding support parts 80 as in-mold cleaning...

Embodiment 2

[0105] Next, refer to Figure 7 to Figure 9 A multiple heating and cooling system for a metal mold according to Embodiment 2 of the present invention will be described.

[0106] The multiple heating and cooling system of the metal mold involved in this embodiment 2 basically has the same structure as the multiple heating and cooling system of embodiment 1, and is characterized in that Figure 7 The shown two-material molding machine 68 replaces the A molding machine 8a and the B molding machine 8b of the first embodiment.

[0107] In the above-mentioned two-material molding machine 68, as Figure 7 As shown, a movable side metal mold (first mold core) 103 connected with the above-mentioned turning disk 102 is arranged on the rear part A side of the movable platform 101 with the turning disk 102, and the movable side metal mold 103 is arranged and fixed. A side mold (first cavity) 104, a take-out gate 105, and a rear cylinder (primary side plasticizing device) 106 supported b...

Abstract

The present invention provides a mold multiple heating and cooling system which, for a plurality of molding machines (8a,8b), allows a single temperature control apparatus to be used to selectively supply steam or warm water, or cooling water for carrying out molding, and eliminates the need for separately installing a venting apparatus. The mold heating and cooling system pertaining to the present embodiment 1 includes a steam heating unit (30), a warm water heating unit (35), and a cooling unit (40) which feed steam, warm water, and cooling water, respectively, to molds (1 to 4) for two molding machines (8a,8b) that include an in-mold temperature sensor TC1 to TC4, respectively. A single temperature control apparatus (10) is disposed between the units and the respective molds (1 to 4) of the two molding machines (8a,8b), connected by a piping therebetween. Control means (50) which, on the basis of a temperature detected by each in-mold temperature sensor (TC1 to TC4) disposed in the respective molds (1 to 4), determines the temperature of the respective molds (1 to 4) on a previously stored temperature determination program for controlling selective supply and discharge of steam or warm water, or cooling water to / from the respective molds (1 to 4) of the two molding machines (8a,8b) according to a molding cycle for each molded article therefor. A mold vacuum system (80) carries out sucking and discharging of the gas and air inside the respective molds (1 to 4), and air blowing for the respective molds under the control of the control means (50).

Description

technical field [0001] The present invention relates to a multiple heating and cooling system of metal moulds, which can use one temperature regulating device to switchably supply steam, warm water and cooling water to a plurality of molding machines for molding, and does not need to be additionally provided with an exhaust device. Background technique [0002] In the past, various heating and cooling systems for metal molds have been proposed. They use temperature control devices to send steam, warm water, and cooling water to the metal molds of molding machines such as injection molding machines and hot presses, and repeat the heating and molding of the metal molds. Forming of products and cooling of metal molds. [0003] However, at present, there is no heating and cooling system for obtaining molded products by switchingly supplying steam, warm water, and cooling water to a plurality of molding machines or two-material molding machines using a single temperature control ...
