摘要： A die cast mold release lubricant comprises a silicone compound. A method of application of the lubricant to a die cast mold as a release agent is disclosed where a die casting machine has a mold with mold halves forming a mold cavity when the mold halves abut against one another, a shot sleeve and a plunger which pushes molten material through the shot sleeve and into the mold cavity. The mold release agent is placed into the shot sleeve remote from the mold cavity, molten material is introduced into the shot sleeve, and the molten material and the mold release agent are forced into the mold cavity by movement of the plunger into the shot sleeve. The silicone compound preferably has a melting point of about 90-220° F., and a molecular weight of about 5500-50,000.

摘要： A method and apparatus for controlling an injection process in cold-chamber die-casting machines which work on a three-phase system whereby an automatic initiation of the third phase without delay is possible. Beginning with the plunger of the apparatus in a certain starting position, the time is measured which elapses until a pressure in a working cylinder ahead of the plunger has reached a predetermined value. The time delay of the valve system which releases the pressure medium feed in the third phase is subtracted from the time measured so as to arrive at a time differential. At the end of the time differential, which elapses when the injection process begins with the plunger in its original or starting position, serves as a starting signal to trigger the valve system.

摘要： A method of casting high temperature melting point metals and a die arrangement and molten metal feed mechanism for a die casting machine. The method includes gravity filling a shot cylinder with molten metal, cutting off the inlet to the shot cylinder when it is full and then forcing the molten metal in the air-free cylinder into the mold cavity. The machine includes die elements adapted to mate and define a mold cavity at a parting line defined by parting surfaces between the opposed faces of the elements. The die arrangement and molten metal feed mechanism includes a sprue and runner complex also disposed at a parting line, and a molten metal injection or shot cylinder which extends into the parting line or lines. The metal shot cylinder is filled through the sprue with the dies closed. In one aspect of the invention, a molten metal injection plunger acts to seal off the sprue from the shot cylinder during a casting operation, while in another aspect of the invention a separate sprue plunger is utilized to perform this function.

摘要： A die-casting process method for die-cast molding of a metal in a semi-solid state, wherein a semi-solid state die-casting machine is used as a processing device and a pulper is used as a device for preparing and delivering a slurry in a semi-solid state; the method comprises the steps: spraying a mold release agent and mold clamping; melting the raw material and keeping the temperature; adding a metal modificator into the molten raw material to prepare the slurry in a semi-solid state; transferring the slurry in a semi-solid state into a mold by the pulper; die-casting, opening the mold and exporting a die-cast; removing the sprue to obtain the final die-cast. In the process method, a metal modificator is added to the liquid metal raw material during the preparation of the slurry in a semi-solid state so as to generate more crystal nuclei, so that die-cast products have better mechanical properties; by way of die-casting the slurry in a semi-solid state, during mold stripping the die-cast is low in temperature and small in deformation quantity, and the best shapes and surface smoothness of the product can be guaranteed; and the die-cast is compact interiorly with producing air holes, and the best interior structure and mechanical properties of the die-cast product are guaranteed.

摘要： A die casting machine includes a stationary die half, an ejector holder block, and die core pieces that extend through the ejector holder block, defining a die cavity when closed. An ejector box backstops the closed ejector holder block and die core pieces. Melt is injected into the die cavity. After a first dwell time, the ejector box is retracted away from the ejector holder block while a closing force is simultaneously applied to maintain the ejector holder block closed on the stationary die half, and the die core pieces are retracted out of the die cavity. After a second dwell time, the melt completely freezes and the ejector block is separated from the stationary die half, opening the die cavity from which the resulting die cast block can be retrieved.
