Abstract

PURPOSE:To improve the strength of a casting by opening the other end of a plunger sleeve having an injection plunger at one end into a cavity and filling a molten metal from a holding furnace into a plunger sleeve by an electromagnetic pump in a way as to avoid intrusion of air into the molten metal. CONSTITUTION:A cavity 14 is formed of a stationary die 11 and a moving die 15 and one end of a plunger sleeve 29 having an injection plunger 30 is opened into the cavity 14. When an electromagnetic pump 24 is operated after the dies 11, 15 are brought into tight contact with each other, a molten metal 21 is poured from a holding furnace 22 via a tapping pipe 23 and nozzles 25-27 into the sleeve 29. Since the cavity 14 communicates with the atm., the molten metal 21 fills the inside of the sleeve 29 without contg. air. The casting obtd. by injecting the molten metal 21 into the cavity 14 by the plunger 30 has improved strength and airtightness.

ドチャンバダイカストマシンヲ提供することにある。Conventional cold chamber die casting machines generally pump up the molten metal from the holding furnace into a ladle or the like and then pour it into the plunger sleeve, so air remains in the plunger sleeve. This air is drawn into the molten metal when the injection plunger is moved forward and injected, resulting in gas porosity occurring in the product, increasing the strength of the product, and reducing the strength and airtightness of the product. In addition, a solidified layer was generated in the plunger sleep portion during advancement at a low injection speed, and this solidified layer was caught in the product and degraded the quality, and remained in the biscuit portion, reducing the casting pressure. 1゛゛ [Object of the invention] The present invention eliminates such drawbacks, and its purpose is to:
To provide a cold chamber die casting machine which prevents gas and coagulation layer from being involved in the product.

を特徴にしている。The cold chamber die casting machine of the present invention includes a fixed die, a movable die, a holding furnace that is installed near the fixed die plate to which the fixed die is attached, and stores molten metal therein, and surrounds the outlet pipe of the holding furnace. An electromagnetic pump, a plunger sleep with one end opened in the cavity formed by both molds and an injection plunger fitted in the other end, and a nozzle that guides the molten metal from the tapping pipe to the plunger sleep. It is characterized by filling the molten metal with an electromagnetic pump to prevent air from being drawn in when the injection plunger moves forward.

When the electromagnetic pump 24 is operated, the molten metal 21 is injected from the holding furnace 22 into the plunger sleep 27 through the tapping pipe 23 and the nozzles 25 to 27. At this time, one end of the plunger sleep 27 opens into the cavity 14 and the cavity 14 communicates with the atmosphere through a narrow gap, so the molten metal 21 flows through the plunger sleep 27 without involving air.
satisfy. Next, when the injection plunger 28 is moved forward (leftward in the figure), the molten metal 21 is injected into the cavity 14. As described above, since the molten metal in the plunger sleep 27 does not contain air, no air is drawn into the molten metal 21 as the injection plunger 28 moves forward.

Air is no longer drawn in when the injection plunger moves forward. As a result, gas porosity does not occur in cast products, resulting in high strength and airtightness. Furthermore, since the plunger sleep is filled with molten metal, the temperature drop of the molten metal is small and injection can be performed at a low speed, and the formation of a solidified layer is also reduced due to the small drop in temperature of the plunger sleep. This also has the advantage of increasing the quality of the cast product and extending the life of the mold.
