It is located at the other end of positioning bolt and repairing mould is locked with copper nut.
The opposite both sides of the upper semi-circle mould and lower half circle mould are both provided with the wing plate for locking, upper semi-circle mould and lower half
Fixed screw, which is corresponded to, on the wing plate of circle mould is equipped with mounting hole respectively.
The thickness 5mm of the wing plate.
A diameter of 10mm of the mounting hole.
The specification of the fixed screw is M8X30.
A diameter of 10mm of the plug hole.
The specification of the positioning bolt and location nut is M12X40.
The utility model uses above technical scheme, convenient to remove mould using the upper semi-circle mould and lower half circle mould divided half-and-half
Tool.The both sides of upper semi-circle mould and lower half circle mould are all welded with wing plate and the design of wing plate mounting hole is consolidated easy to the locking of fixed screw
It is fixed.The effective copper nut for coordinating tap of the setting of location hole, positioning bolt and location nut realizes positioning, ensure that repairing
Mould injection molded shapes, ensure that repair efficiency meets standard and expection.
The utility model is simple in structure, easy to use, and the effect after repairing is preferable, has retrieved because the tap of coil has
Cracking, phenomenon of rupture and scrap coil economic loss.
Brief description of the drawings
