Additional mould locking device of indirect extrusion casting

Abstract

An additional mould-locking apparatus for indirect extrusion casting features that an additional mould-locking pull rod is used between upper and lower mould seats, its one end is fixed to lower mould seat, its another end has a mould-locking gap regulating block, and a hydraulic cylinder is fixed to a connecting plate for upper mould and its seat for driving the mould-locking block in order to lock or unlock mould.

Description

technical field

[0001] The invention relates to squeeze casting, in particular to an additional clamping device which can increase the clamping force and realize mold clamping and pouring during the indirect squeeze casting process by using a vertical press. Background technique

[0002] Squeeze casting is a process in which a certain liquid or semi-solid metal is injected into a metal mold cavity, and then mechanical static pressure is applied to make it crystallize, solidify and form under pressure. Among them, indirect squeeze casting can produce large, complex and dimensionally accurate parts, which is the main development direction. The equipment currently used in squeeze casting production in my country is mainly obtained by improving the general vertical press. Its main procedures and features are: 1) Preheating the mold, opening the upper and lower molds in turn to clean the cavity and spray paint; 2) Manually pour the alloy solution into the...
