Description

Technical Field

[0001] The utility model relates to the technical field of liquid die forging, in particular to a liquid die forging production equipment for glass mold blanks with a duplex displacement and removal workbench. Background Art

[0002] All along, the production methods of glass mold blank castings have mainly been sand casting such as clay sand molding casting, shell molding core pouring, and resin sand casting. Sand casting is one of the most common casting processes. Using a sand mold as a mold, molten metal or alloy is poured into the mold. After it cools and solidifies, the mold is removed to obtain the required parts. The sand casting process is simple and low-cost, suitable for producing large quantities of parts. However, since sand casting requires a large riser to be set, the material utilization rate is low, and various casting processes are relatively complex, resulting in a high scrap rate, low surface quality, and low casting process yield.

[0003] Die casting, that is, pressure casting, is to use high pressure to inject molten metal into a precision metal mold cavity at high speed. The molten metal cools and solidifies under the action of pressure to form a casting. During die casting, the molten metal bears high pressure and has a high flow rate, with advantages such as good product quality, stable dimensions, and high production efficiency. Die casting molds can be used many times and are suitable for large-scale mass production. And existing vertical liquid forging machines face problems such as runner casting, slag entrainment, and porosity defects that are difficult to avoid,

[0004] It is difficult to achieve large-volume pouring, leading to problems such as spheroidization recession and poor quality consistency of ductile iron and vermicular iron: Moreover, the time for casting, part taking, and spraying coating is too long, and it is time-consuming and laborious to replace the mold inside the machine.

[0005] To overcome the deficiencies of the above-mentioned prior art, the utility model provides a liquid die forging production equipment for glass mold blanks with a duplex displacement and removal workbench. By adopting a liquid die forging equipment and technology without a sand mold and without a riser to produce glass mold blank castings, the problems of low material utilization rate of glass mold blanks and low casting yield are solved.

[0032] First, two sets of liquid forging dies 30 required for die casting production are respectively installed at the designated positions on the first movable workbench 17 and the second movable workbench 18. The melting furnace melts qualified molten steel. After the molten steel is fed with wire for vermicularizing treatment and then lifted by a crane to the liquid forging equipment for waiting for pouring. If pouring starts from the left pouring station, the first movable workbench 17 stops on the left slide rail, and the crane lifts the melted molten iron and quantitatively pours it into the liquid forging die 30 on the first movable workbench 17 from the gate position on the upper plane of the first movable workbench 17; after that, after pouring is completed, the first movable workbench 17 runs along the slide rail under the drive of the driving motor 19 onto the floating guide rail 11 on the base 25 and enters the liquid forging position.

[0033] Finally, the mold opening and closing oil cylinder 12 pushes to open the upper and lower dies of the liquid forging die 30 that are combined together, and the ejector oil cylinder 31 ejects the liquid forging casting. After the ejector oil cylinder 31 resets, the liquid forging die 30 is purged and sprayed with a coating. Then, the mold opening and closing oil cylinder 12 pulls the dies together and waits for the next casting again. At this time, the liquid forging die 30 in the second moving workbench 18 has completed casting and entered the liquid forging position. The liquid forging machine extrudes and solidifies the liquid forging die 30 on the workbench. After solidification is completed, it is moved out to the right casting position to the right, and the mold is opened to take out the part, sprayed with a coating, and the mold is closed, waiting for casting. In this way, the work cycle is repeated to achieve continuous production.
