The first plate includes mainboard body 1a, the runner saddle being arranged on mainboard body, and sprue is arranged on runner saddle,
Spot pouring mouth number is 6 to 12, and each spot pouring mouth is circumferentially uniformly distributed along sprue.
The spot pouring mouth is arranged in the first template, and runner saddle includes that trumpet assembly runner plate 1b and some runner plates are spelled
Block 1c.
The pusher rod axis overlap with mold cavity axis, and core is provided with the guide section 3a being slidably matched with charging ram.Will
The workpiece of molding is rotor class workpiece, and it possesses central axis, the centrally disposed place of charging ram (pusher rod axis and mold cavity axis
Overlap), be conducive to allowing forming part stress evenly when forming part is ejected, further ensure and be difficult during part removal
It is impaired.The presence of guide section, then can lift the moving stability of charging ram.
The first plate is provided with some promotion isolating constructions 71 for promoting the first template, and first plate is provided with least one
Protection core-pulling mechanism 72, protects pulled core structure to include limited block 721 and the core pulling oil cylinder 722 for driving limited block to move, and takes out
The cylinder body of core oil cylinder is connected with first plate, and limited block is provided with for stretching into the spacing head 721a in sprue.
The promotion isolating construction includes auxiliary ejection oil cylinder 711, and the cylinder body of auxiliary ejection oil cylinder is connected with first plate, aids in
The piston rod of ejection cylinder is provided with the impeller for promoting the first template to move away from first plate direction.
After forming parts, spacing head is in sprue, thus spacing head can with sprue in solidify material (solidification
Liquid metal) combine, so as to effectively hold the waste material solidified in spot pouring mouth, can be preferably between part and waste material during the guarantee demoulding
Break, further, since the presence of spacing head, allows waste material to occur in that intensity part (weakness) on the weak side, so as at this more
Easily it is pulled off, so in the demoulding, can effectively force waste material weakness fracture in spot pouring mouth, after fracture, position limiting slide block is taken out again
Core, waste material can the smoothly demoulding in sprue.
