Mold for producing aluminum soup pot with pot lugs and production method adopting mold

Abstract

The invention discloses a mold for producing an aluminum soup pot with pot lugs and a production method adopting the mold. The mold comprises an upper mold connecting plate, a lower mold connecting plate, a female mold which is fixed to the upper mold connecting plate and a male mold which is fixed on the lower mold connecting plate and is mutually matched with the female mold, a guide ring is further fixed on the lower mold connecting plate, the guide ring sleeves outside the male mold, moreover, a gap is reserved between the guide ring and the male mold to form a pressure regulating groove,a stripping ring is connected in the pressure regulating groove in a sliding mode, an air inlet channel communicating with an adjusting groove is formed in the lower mold connecting plate, and an annular groove used for forming the pot lugs is formed in the end surface of the stripping ring. An original elastic rubber block is omitted, the air pressure in the pressure regulating groove is controlled to control the fluidity of the aluminum material, moreover, an elastic part is arranged at the bottom of a returning block, so that the elastic linear change of the elastic part is kept constant, only the pressure adjustment in the pressure regulating groove is required to be performed for the single-sided control, the actual operation and the calculation process are facilitated, one-time forming is achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a mold for producing an aluminum pot, in particular to a mold for producing an aluminum soup pot with pot ears and a production method using the mold. Background technique [0002] Existing aluminum pots generally include pot ears and a pot body, and the pot ears are fixed to the pot body by riveting or welding. This method is not high in connection strength and the process is relatively complicated. In order to solve the above problems, "a kind of aluminum pot and its manufacturing method" is disclosed in the invention with the notification number CN100345509. It adopts the die-casting method to forge the pot ears and over 100 million forging at one time, but due to the large investment in die-casting equipment , Enterprises with low production efficiency rarely use it. [0003] The most commonly used at present is stretching method, for example, discloses " a kind of secondary molding method of aluminum pan body " in publica...

AI Technical Summary

Problems solved by technology

[0004] In addition, during the forming process, the aluminum sheet will flow under the action of the mold clamping pressure, and the aluminum material will gradually fill the gap between the punch and the die, and the moving speed of the push block and the ejection ring determines the aluminum material’s movement speed. The flow speed will affect the molding quality, but because the elastic rubber block at the bottom of the stripping ring and the push block is prone to aging over time, which will affect the molding effect
