Therefore, by the venting opening of the mold, the upper part of the A _ 八uq upper part is shaped, the self-finishing is made by the cavity C and the closed space of the sleeve 30 is vented. When the shot formed by the skin is initially started by the evacuation of the vacuum device 61, there is a system, for example, as shown by the dotted line in Fig. 4, the cold is moved toward the exhaust port 5h. i = 2 is from the cavity C The introduction portion Cin is oriented toward the exhaust port 5h near the most/clothing portion of the die 2. After the start of the exhaust of the front true air device 61, or as shown by the exhaust start, the hydraulic cylinder 77 is driven. The pressing pin 71 is protruded from the inlet C. At this time, the other pressing pin 72 does not move. The |, |, the powder releasing agent ps is supplied from the powder supply device 85 to the pressing pin 71. The supply line for the molding agent is used. The powder release agent PS passes through the supply path of the release agent of the extrusion pin 71, and the opening of the front end portion of the extrusion pin 71 from the dog to the cavity C faces the cavity c.

Next, as shown in Fig. 6, the plunger 4 is lowered toward the arrow so that the front end portion of the plunger 40 is located below the liquid supply port 31h of the solution supply tube 5'. In this state, the powder supply lubricant 85 is supplied from the powder supply device 85 to the lubricant supply path of the extrusion pin 71. As shown in Fig. 6, the front end portion of the self-pressing pin 7 is sprayed with the powder lubricant PG' to the sleeve 3 to apply the powder lubricant pG to the inner circumferential surface of the sleeve 3. After the predetermined amount of the powder lubricant PG is supplied, the supply of the powder lubricant pg from the powder supply device 85 is stopped. After the application of the powder lubricant pG on the inner circumferential surface of the sleeve 30 is completed, the hydraulic cylinder 77 is driven as shown in Fig. 7, so that the front end portion of the extrusion pin 71 is immersed in the moving mold 6. Thereafter, the metal solution ML is supplied into the sleeve 30 through the solution supply tube 5?. Therefore, the metal solution ML is housed in the sleeve 40 in the closed state by the plunger 40. Next, as shown in Fig. 8, the plunger 4A is raised toward the arrow ^, and the front end portion of the plunger 40 moves the liquid supply port of the sleeve 30 to the position where it is closed.

INSTRUCTION OF THE INVENTION (11) ^ When the mold 6 is used, the cast product W moves from the fixed mold 5. f moving the cooker 6 - after moving the moving template 3 to the predetermined position, the drive-out plate 73 is moved in the direction of the arrow, so that the press-out pin 22 2 is used to move the recesses 6a, 6b of the movable mold 6 The mold is released from the moving mold 6 by the extrusion pin; By the above process, the cast product W is obtained. In the case of the f 1 embodiment, the mold cavity c is exhausted in the mold-like mold in which the mold 5 and the mold 6 are closed, and the powder is removed by the flow of the two gas in the cavity c generated by the exhaust gas. The molding agent is sufficiently diffused to adhere to the inner surface of the cavity C. As a result, regardless of the shape of the cavity c, etc., the powder release agent PS can be used. Further, in the present embodiment, the exhaust port 5h for exhausting the cavity C is disposed at the deepest portion of the cavity f, and the extrusion pin 71 protrudes from the introduction path Cin of the cavity C, and is self-pressed. The front end of the pin 71 will be a powder release agent? 3 Jetting toward the mold c side allows the powder release agent PS to pass over the entire cavity c. As a result, coating unevenness of the powder release agent ps does not occur, and the mold release and heat insulation performance of the powder release poly PS can be sufficiently exhibited. Further, in the present embodiment, after the application of the powder release agent ps, the powder lubricant is sprayed toward the sleeve 30 by the front end portion of the extrusion pin 71 in a state of protruding from the concave portion 6b of the movable mold 6. Pg, the powder lubricant PG can be applied to the entire inner circumference of the sleeve 30. Further, in the present embodiment, the powder supply device 85 that supplies the powder release agent PS and the powder lubricant PG to the extrusion pin 71 is removed from the molds 5, 6.
