Under, runner waste material (or product) mechanical hand folder is walked.At present, a lot of mould offside pouring gate structures are improved so that it is can be certainly
The dynamic sprue channel that cuts off coagulates material.But, there are the following problems for existing side gate solidifying material automatic-sheared structure: mould die sinking ejects
Time, need first product is ejected so that sprue channel coagulates material and stays dynamic model, treat product under the effect of flat thimble with sprue channel
After solidifying material departs from, runner ejector pin ejects runner again, i.e. sprue channel is coagulated material and ejects, and it is mainly cut with cast gate by flat thimble
Between disconnected mold insert, formation shearing force is by gate cutting, because cutting off mold insert and flat thimble rigidity and limited strength, so cast gate is not
Can be too big, the cut-out mold insert simultaneously that otherwise cannot break is easily broken off, so being suitable only for smallclothes.For this reason, it may be necessary to a kind of side gate
Shearing device, solves the problems referred to above in the presence of prior art so that it is be applicable to the product that big part, i.e. gate size are bigger
Product.
