Description

A kind of slide block combination locking mechanism of die casting
Technical field
The present invention relates to the design and manufaction technical field of die casting, specifically a kind of slide block combination locking mechanism of die casting.
Background technology
Die casting is a large class in mould.In recent years, along with China's automobile, the developing rapidly of motorcycle industry, Die Casting Industry has welcome the new period of development.But meanwhile, also the comprehensive mechanical property of die casting, life-span and mould structure etc. are had higher requirement.
Die casting is a kind of production process of precision, but has several factors but can affect the final size change of die casting.Change in size can be divided into again linear change (mainly causing owing to shrinking), the mobile dislocation between mould, die parting line, foundry goods and mould warpage, and die casting parameter, looses core and draft angle etc.But the final size having any must remember die casting change just depends in part on mould and die accuracy, it also has close relationship with following factor: the normal fluctuation of mould temperature in press casting procedure, injection temperature, cooling velocity, the structure etc. of casting stress release and mould.For reducing the change in size of final products, necessary strict production control operation, optimizes mould structure.
The current structure due to die casting becomes increasingly complex, and is generally used at the structure top shoe of die casting.And in press casting procedure, the mould invalidation that slide block mechanism causes not due to clamp force happens occasionally, the serious mould that also can cause bursts apart, independent locking block device often acts on not quite, and its maximum shortcoming is exactly make the profile of mould increase, therefore a kind of combination locking mechanism is devised in order to address this problem us, this mechanism can effectively avoid slide block not tight, loosen, the defects such as mould bursts apart, this not only substantially increases slide block and mold use life-span, and can ensure that the final size of die casting is stablized, and then raising product percent of pass, reduce the cost that mould is safeguarded.
Summary of the invention
