Heated material forming tool or tool part comprises a single component module and a further module formed of plates and including a temperature control fluid channel

摘要

Tool construction comprises two or more modules joined together. At least one module(2) comprises a single component and at least one additional, heatable, module(3) comprises stacked plates. A channel or channel system(4) in the heatable module is formed by openings in each plate which communicate with each other. Temperature control fluid flows through the channel for heating or cooling the tool or tool part(1). Modules are tightly connected together to prevent fluid leakage. The heating module(3) has one or more fluid inlets(5) and outlets(6). Single component modules(2) have a negative cavity(7) for forming products. Material of the heatable module has a higher thermal conductivity than material used in the other modules. Plates forming heated modules are bonded, soldered or welded together and can be dismantled if necessary. Different thickness plates may be included in a stack. A heating module may be cast directly into a single component module. A stepped outer edge may be created with plates of a heating module and this type of module inserted into a recess with a complentary shape in a single component module.
