Description

Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to a die-casting device for hardware products. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting. They are used to fix things, process things, decorate, etc. Hardware usually has various shapes, so when the hardware is processed and shaped, die-casting equipment is needed to shape it. Die-casting is a metal casting process, which is characterized by using the inner cavity of the mold to apply high pressure to the molten metal. The mold is usually made of a higher strength alloy. This process is somewhat similar to injection molding. Most die-cast castings are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, lead-tin alloys and their alloys. Depending on the type of die-casting, a cold chamber die-casting machine or a hot chamber die-casting machine is required. The cost of casting equipment and molds is high, so the die-casting process is generally only used for batch manufacturing of large quantities of products. It is relatively easy to manufacture die-cast parts, which generally only requires four main steps, and the unit cost increment is very low. Die-casting is particularly suitable for manufacturing a large number of small and medium-sized castings. Therefore, die-casting is the most widely used one among various casting processes. Compared with other casting technologies, the surface of die-casting is smoother and has higher dimensional consistency.

[0003] After searching, a die-casting device for processing hardware accessories is disclosed with the publication number CN213410267U, which specifically discloses a die-casting device for processing hardware accessories, including an equipment table, a first mounting plate is fixedly connected to the top of the equipment table, a second mounting plate is fixedly connected to the top of the equipment table and located on the right side of the first mounting plate, and a load-bearing plate is fixedly connected between the first mounting plate and the second mounting plate on the opposite side. The utility model provides a die-casting device for processing hardware accessories, which drives the spur plate to retract through the cylinder, and the spur plate drives the gear to rotate, thereby rotating the mounting rod, and the mounting rod drives the second connecting rod to rotate, and the second connecting rod lifts the first mold through the first connecting rod, and the first mold rotates and lifts upward with the rotating axis as the center point, and the hardware accessories inside the first mold are poured out, thereby realizing automatic demolding of the hardware accessories, saving time, and improving equipment production efficiency.

[0004] The die-casting device proposed in the above patent cannot quickly cool and shape the hardware during the die-casting process, which will cause the hardware to cool slowly after die-casting, thereby affecting the demolding efficiency of the hardware and making the die-casting device less efficient to use.

[0005] Therefore, it is necessary to invent a die-casting equipment for hardware products to solve the above problems. Utility Model Content

[0008] Preferably, a side plate is fixedly mounted on the upper end of the shell, an electric telescopic rod is fixedly mounted on one side of the side plate, and a cross plate is welded to the other end of the electric telescopic rod.

[0009] Preferably, a sliding groove is provided on the other side surface of the transverse plate, the inner wall of the sliding groove is movably connected with a slideway, and a bottom mold is fixedly installed on the other side of the slideway.

[0014] 1. Through the arrangement of the fan slot, the cooling fan, the dust screen and the screw, the fan slot is opened on the operating table installed at the upper end of the shell, which can facilitate the subsequent installation and use between the cooling fan and the shell. The arrangement of the cooling fan can play a role in rapid cooling and shaping of the hardware inside the bottom mold after die-casting, which brings convenience to the demoulding of the hardware and improves the processing efficiency of the die-casting device. The arrangement of the dust screen can play a role in dust prevention when the cooling fan is in use, preventing dust from being adsorbed on the cooling fan, affecting the speed of the cooling fan, etc., and is inconvenient in subsequent cleaning.
