Abstract

PURPOSE:To decrease the stroke of a die clamping cylinder of a casting machine and to reduce the sizes of an oil hydraulic device and the body of the casting machine by providing a stopper attachably and detachably to and from the spacing between the die clamping cylinder and a housing. CONSTITUTION:A lower stationary stand 3 and a movable slider 4 are provided in the housing 2 of a casting device 1. A die clamping cylinder 6 and a ram 7 are installed on the slider 4, and the slider 4 is moved by a stroke (a) with a side cylinder 5. A stopper 9 is inserted attachably and detachably by using an inserting cylinder or the like. Thus the stroke of the cylinder 6 is enough with the size (b) taking the elongation, etc. of the frame by die clamping into consideration and the volume of working fluid is economized. The cycle time of casting is reduced.

備費が高価になった。In conventional casting machines, the mold clamping cylinder is fixed to the housing, so when the slider is lowered at high speed by the side cylinder, in order to supply a large amount of hydraulic oil into the mold clamping cylinder, the oil tank at the top of the casting machine is used. It had to be made larger, which had the disadvantage of increasing the height of the casting machine. In addition, it takes time to increase the pressure of the hydraulic fluid in the mold clamping cylinder due to its compression, resulting in a long casting cycle time. As a result, the unit price of cast products increased, and the cost of building equipment and casting machine equipment became expensive.

、設備価格の低減を達成可能とした。Conventional vertical direct pressure casting machines require a large amount of hydraulic oil to be used in the mold clamping cylinder, which has been a problem in increasing the mold clamping speed. The method of containing the movement of the mold clamping cylinder with a stopper made it possible to reduce the mold clamping stroke, shorten the casting cycle time, and reduce equipment costs.

、設備費が従来に比べて安価になる効果がある。An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. A lower fixed frame 3 and a movable slider 4 are provided in the housing 2, a mold clamping cylinder 6 and a ram 7 are installed on the slider 4, and the slider 4 is moved by a stroke a using a side cylinder 5. The stopper 9 is attached and detached by moving the stopper insertion cylinder 10 by C' dimension (see FIG. 3). The mold clamping cylinder stroke is sufficient to take into account the elongation of the frame due to mold clamping, and a large amount of hydraulic oil can be saved. This has the effect of shortening the casting cycle time, making the embroidered rock smaller, and lowering equipment costs compared to conventional methods.
