The present disclosure relates to a casting apparatus including a support block, a die provided on one surface of the support block and configured to form a cavity in cooperation with the support block, and an insert member provided to be movable relative to the support block and configured to selectively move between a first position at which the insert member is received in the cavity and a second position at which the insert member is extracted out of the cavity, thereby obtaining an advantageous effect of simplifying a structure and a manufacturing process.

A three-plate pressure die casting mold for producing at least one metallic die casting part by die casting a metal melt, includes first, second and third mold parts and at least one mold cavity as well as a sprue system. In the third mold part there is at least one spring-loaded pressure element which, when opening the die casting mold, presses the sprue produced in the sprue system against the first mold part, whereby the sprue is retained and tears off from the die casting part in a defined manner. A method for pressure die casting using the three-plate pressure die casting mold is disclosed.

A three-plate pressure die casting mold for producing at least one metallic die casting part by die casting a metal melt, includes first, second and third mold parts and at least one mold cavity as well as a sprue system. A relatively movable pressure plate is arranged in the third mold part, which, when opening the die casting mold, presses the sprue produced in the sprue system against the first mold part, whereby the sprue is retained and tears off from the die casting part in a defined manner. A method for pressure die casting using the three-plate pressure die casting mold is disclosed.

Provided is a testing machine for simulating a die casting cooling process, including a mold base, a stationary die, a moving die, a guide rod, an ejector rod, a mold clamping device, a point cooling device housing, a cooling water channel, a heating coil, a heating block and a heating bar; a point cooling unit includes the point cooling device housing and the cooling water channel, a plurality of heating bars regularly arranged on the moving die constitute a pre-heating unit, a thermocouple is arranged at the point cooling unit, a temperature signal is connected to a controller, the heating coil and the heating block constitute an external heating unit, the point cooling unit is connected to a cooler, a cooling water tank, a filter and a water pump to constitute a cooling device, the controller and a ball valve constitute a control system.

A hybrid core for manufacturing a cast component, the hybrid core including a sand core portion having an exterior shape configured to define an interior feature of the cast component. The hybrid core also includes a metal chill element embedded within the sand core portion. The metal chill element is configured to locally absorb heat energy from the cast component during cooling of the cast component and solidification thereof. The metal chill element is constructed and arranged within the sand core portion to be removed during shake out from the cast component subsequent to the solidification thereof. A system and a method for manufacturing a cast component using such a hybrid core are also envisioned.

A cold flake suppression method is provided. A molding device includes a sleeve, a tip, a sprue guide portion, a molding die, a sprue ring, a distributer, and a control device. The sprue guide portion includes a stamp portion, a runner portion, and a gate portion. The control device drives a supply device to slide the tip for molten metal to flow through the sleeve; sequentially calculates an amount of heat transfer changing continuously from the start of supply of molten metal until the tip slides to the position in FIG. 2, and calculates a total of the amounts as a total amount of heat transfer; and calculates a volume of the sprue guide portion based on information about the sprue guide portion input by an operator. Shapes of the sleeve and the sprue guide portion are determined to set a cold flake index equal to or less than 0.842.

A molding machine of an embodiment includes: a base; a fixed die plate holding a fixed die; a movable die plate provided on the base and closing direction and holding a movable die to face the fixed die; a toggle mechanism capable of clamping the fixed die and the movable die; a link housing provided on the base and allowing one end of a link of the toggle mechanism to be fixed thereto; a first motor driving the toggle mechanism; a second motor moving the movable die plate and the link housing; an extrusion plate allowing an extrusion pin to appear and disappear in the movable die; a guide bar fixed to any one of the link housing and the movable die plate, penetrating the extrusion plate, and slidably holding the extrusion plate; a positioning member positioning the extrusion plate; a tie bar; and an injection device.
