Abstract

Equipment for checking the characteristics of an injection moulding tool, comprising a chamber which can heat and melt a fusible material such as wax and expel the material by use of a pneumatic ram via a nozzle which fits the tool gate so as to fill the mould cavity with a liquid which may be frozen in situ. The outlet nozzle incorporates a valve. Suitable for filling moulds to check for cavity dimensions, undercuts, parting line misalignment or other faults, i.e. for checking tool design during tool manufacture. Simulates use of an injection moulding machine and material for filling the tool, with much lower costs and need for space than using an actual injection moulding machine. The injected liquid indicates parting line flaws etc. by leaking readily. The solidified melt reproduces cavity form and detail.
