Abstract

The utility model relates to a casting device, in particular to a metal mold casting device, which resolves problems of waste of raw materials, low quality and high cost of finished products and the like in casting processes of body building instruments such as kettle bells or dumbbells. The metal mold casting device comprises an upper metal mold and a lower metal mold, wherein a casting cavity is formed between the upper metal cavity and the lower metal cavity, an upper removable mold and a lower removable mold are arranged in the casting cavity, a supporting rod hole is arranged between the upper removable mold and a lower removable mold, a casting channel is arranged on the upper metal mold and covered with a sand mold, and exhaust holes penetrate through the upper metal mold and the lower metal mold. The metal mold casting device is reasonable and skillful in design and can save material, increase production efficiency and improve product quality.

Description

The permanent mold casting device

Technical field

The utility model relates to a kind of casting device, is specially a kind of permanent mold casting device.

Background technology

Up to the present, the method for casting production of body-building apparatus such as kettle-bell or dumbbell adopts by hand always and stirs moulding, the method for large-scale riser feeding, and its maximum drawback is: hand labor intensity is big, and cast(ing) surface is coarse, and presentation quality is poor; The feeding appetite is big, and shrinkage cavity shrinkage porosity is many, and the molten iron waste is big, and the molten iron utilization rate is low, and the percent defective height is given the later process sand removal, and polishing is stuck with paste sheet and brought very big workload.And workman's operating environment is abominable, takes a lot of work, and is time-consuming, and effort is taken material, and cost is high, directly causes manufacturer profitless, and the user is also discontented to quality.

Summary of the invention

Problems such as the utility model is for wasting raw material of occurring in the casting process that solves body-building apparatus such as existing casting kettle-bell or dumbbell, the low-cost height of end product quality and a kind of permanent mold casting device is provided.

The utility model is realized by following technical scheme; a kind of permanent mold casting device; comprise metal mold, bottom die; form casting cavity between last metal mold, the bottom die; be provided with the live mould and the mould of living down in the casting cavity, be provided with support rod hole between mould and the mould down alive, on last metal mold, be provided with sprue last living; sprue is a sand mold outward, passes metal mold and last mould alive also is provided with steam vent.

The utility model in use, need at first in last cavity of living between mould and the mould down alive, to place chill, described chill is connecting support bar, support bar passes support rod hole makes chill unsettled in cavity, then molten iron is poured in sprue, molten iron enters in the slit that forms between chill and the cavity, behind the molten steel solidification promptly and the chill core be set in together.

Compared with prior art, maximum characteristics of the present utility model are being offered support rod hole exactly between last metal mold and bottom die, and then that chill is logical support bar is put into wherein, again casting.Have following outstanding advantage: 1, labor strength is little, and personnel take few.2, surface quality of continuous castings is good, and is highly polished, and the class height has improved the market competitiveness.3, cancel feeding head, greatly improved the molten iron utilization rate, reduced production cost; 4, foundry goods does not have fash, burr, does not have neck residual, and sand removal, polishing, paste sheet workload are little, and the environment clean hygiene; 5, yield rate height, the production efficiency height, the place takies few, the laborsaving material-saving of saving of work and time; 6, the design of adopting the mould of living to inlay in the metal mold, the Mould Machining expense is low, and one module multiple usages can exchange, and the life-span is longer.7, sprue adopts molding sand to make outward, and molten iron flows in molding sand fully, and is not only easy to use, and protected metal mold effectively and prolonged service life.8, place chill in the metal mold earlier, can replace a large amount of molten iron, have very high economic benefit and social benefit.
