Supply method and supply apparatus of semi-solid metal

Abstract

A supply apparatus supplies a semi-solid metal to a molding apparatus having an injection sleeve formed with an opening portion and a plunger provided progressively/regressively at an inner portion of the injection sleeve. The supply apparatus includes a crucible in a shape of a cylinder containing a semi-solid metal, a carry arm for grabbing to move the crucible, and a control apparatus for controlling the carry arm. The control apparatus inserts a front end portion of a gutter mounted to the crucible into the opening portion of the injection sleeve by a predetermined angle to inject the semi-solid metal to a side of a direction of advancing the plunger more than at a position formed with the opening portion at inside of the injection sleeve.

1 . A supply method of a semi-solid metal for supplying the semi-solid metal to a molding apparatus having an injection sleeve formed with an opening portion and a plunger progressively/regressively provided at an inner portion of the injection sleeve, the supply method comprising:
 a first step of producing the semi-solid metal from a molten metal at an inner portion of a vessel in a shape of a cylinder; and   a second step of supplying the semi-solid metal in the vessel to the inner portion of the injection sleeve by inserting a front end of the vessel into the opening portion of the injection sleeve by an arbitrary angle;   wherein at the second step, the semi-solid metal is injected to a side in a direction of advancing the plunger more than at the opening portion.   
   
   
       2 . The supply method according to  claim 1 , wherein a gutter is provided on a front end side of the vessel; and
 wherein at the second step, a front end of the gutter is inserted into the opening portion by the arbitrary angle and the semi-solid metal is injected from the front end of the gutter.   
   
   
       3 . The supply method according to  claim 2 , wherein the gutter is configured to be attachable and detachable to and from the vessel. 
   
   
       4 . A supply apparatus of a semi-solid metal for supplying the semi-solid metal to a molding apparatus having an injection sleeve formed with an opening portion and a plunger progressively/regressively provided at an inner portion of the injection sleeve, the supply apparatus comprising:
 a vessel in a shape of a cylinder for containing the semi-solid metal;   a carry arm for grabbing and moving the vessel; and   a controlling apparatus for controlling the carry arm;   wherein the control apparatus inserts a front end of the vessel into the opening portion of the injection sleeve by an arbitrary angle and injects the semi-solid metal in the vessel on a side in a direction of advancing the plunger more than at the opening portion.   
   
   
       5 . The supply apparatus according to  claim 4 , wherein the carry arm includes a gutter capable of being connected to the vessel;
 wherein the controlling apparatus connects the gutter to the vessel, inserts a front end of the gutter into the opening portion by the arbitrary angle, and injects the semi-solid metal from the front end of the gutter.   
   
   
       6 . The supply apparatus according to  claim 5 , wherein the gutter is constituted by a shape of a groove.
