Embodiment Construction

[0021] Exemplary embodiments of the present invention will be described below. It should be noted that the technical scope of the present invention is not limited to the embodiments described below.

[0022] will refer to figure 1 The die casting apparatus 30 according to the embodiment of the present invention will be described. In this manual, for convenience, the figure 1 The right side in is the right side of the die casting equipment 30 and figure 1 A description is provided in the case of the left side of the die casting apparatus 30 on the left side.

[0023] Such as figure 1 As shown in , a mold 1 of a die casting apparatus 30 has a cavity 4, and the mold 1 is provided with a plunger sleeve 2 having a substantially cylindrical shape. The plunger sleeve 2 communicates with the cavity 4 and protrudes leftward from the mold 1 . A plunger tip 3 in a short cylindrical shape is configured to slide rightward in the plunger sleeve 2 to squeeze molten metal 5 such as alum...

Abstract

A die casting apparatus (30) includes: an electromagnetic pump body (40) disposed at a plunger sleeve (2)-side end portion of a molten metal holding furnace (50); and a connecting pipe (41, 42) connected to the electromagnetic pump body (40) and the plunger sleeve (2) to provide communication between the electromagnetic pump body (40) and a molten metal feed port (6), the connecting pipe (41, 42) being separable from the electromagnetic pump body (40). The die casting apparatus (30) further includes a moving mechanism (51) configured to allow the electromagnetic pump body (40) to move between an inclined state where the electromagnetic pump body (40) is inclined with respect to a horizontal plane in the molten metal holding furnace (50) at an angle of approximately 45 degrees and an upright state where the electromagnetic pump body (40) is perpendicular to the horizontal plane in the molten metal holding furnace (50).

Description

technical field [0001] The present invention relates generally to a die casting apparatus, and more particularly to a die casting technique in which casting is performed by injecting molten metal into a cavity of a mold. Background technique [0002] In the die-casting equipment according to the related art, the following technology is adopted: the pump provided at the molten metal holding furnace and the molten metal supply port of the plunger sleeve communicate with each other through a connecting pipe; The molten metal is injected into the plunger sleeve via a connecting pipe (for example, see Japanese Patent Application Publication No. 2013-66896 (JP 2013-66896A)). [0003] In the die casting apparatus described in JP2013-66896A, a pump is fixed to a molten metal holding furnace. This configuration narrows the working space for replacing, for example, the plunger tip or the support shaft, thereby hampering maintenance efficiency. Contents of the invention [0004] Th...
