Above-mentioned disintegrating machine is with cutter tooth seat mold, and big thermal center place is provided with internal densener at wall thickness, and cutter tooth seat foundry goods inside can not form shrinkage cavity and shrinkage porosite, helps obtaining closely knit foundry goods, guarantees inherent quality, reaches Design Requirement Drawing.
Above-mentioned disintegrating machine is with cutter tooth seat mold, and big thermal center place is provided with external chill at wall thickness, and cutter tooth seat foundry goods inside can not form shrinkage cavity and shrinkage porosite, helps obtaining closely knit foundry goods, guarantees inherent quality, reaches Design Requirement Drawing.
A kind of disintegrating machine may further comprise the steps with cutter tooth seat plane vertical pouring casting technique:
A. the flat cutter tooth seat core of doing;
B. vertical pouring: cutter tooth seat core erected pour into a mould; On cutter tooth seat bottom and top end machined surface, step gating system is set; Cutter tooth seat top end machined surface is provided with two rising heads, running gate system and rising head all with cutter tooth seat core UNICOM.
Above-mentioned disintegrating machine is with cutter tooth seat plane vertical pouring casting technique, and said running gate system is a staged buffering running gate system.
Above-mentioned disintegrating machine is with cutter tooth seat plane vertical pouring casting technique, and big thermal center place is provided with internal densener at wall thickness, and cutter tooth seat foundry goods inside can not form shrinkage cavity and shrinkage porosite, helps obtaining closely knit foundry goods, guarantees inherent quality, reaches Design Requirement Drawing.
Above-mentioned disintegrating machine is with cutter tooth seat plane vertical pouring casting technique, and big thermal center place is provided with external chill at wall thickness, and cutter tooth seat foundry goods inside can not form shrinkage cavity and shrinkage porosite, helps obtaining closely knit foundry goods, guarantees inherent quality, reaches Design Requirement Drawing.
Adopt technique scheme, the present invention has following advantage: the present invention adopts the plane vertical pouring mode, and running gate system adopts ladder buffer-type running gate system; I.e. two ladder buffer-types sealing refractory brick running channel; External chill combines and dwindles the modulus of foundry goods in adopting, and reduces the method for thermal center, adopts with original same 2 big rising heads to be arranged on the machined surface of cutter tooth end face; Product yield is increased to more than 70%; Rising head must not polished after cutting and putting down, and has reduced labour intensity, has improved the internal quality of casting and surface quality.
Through practice demonstration repeatedly, adopt plane vertical pouring explained hereafter disintegrating machine to use the cutter tooth seat, guaranteed the packing of foundry goods, presentation quality and inherent quality all are guaranteed, casting yield 100%.
