Aluminium alloy compression casting pan with compound bottom and compound technique thereof

Abstract

The invention relates to an aluminum alloy die-casting pan with a composite bottom, which comprises an aluminum alloy die-casting pan body and a stainless iron composite bottom plate, and is characterized in that the stainless iron composite bottom plate is directly overlaid with the bottom part of the pan body to integrate as a whole. The invention also relates to a complex process of the aluminum alloy die-casting pan with the composite bottom, wherein, the steps of die casting, surface cleaning, complexing agent coating, plate pasting, compounding, pressure retaining, cooling, surface follow-up processing, and the like, are adopted to form the aluminum alloy die-casting pan with the composite bottom. The aluminum alloy die-casting pan with the composite bottom in the invention has the advantages of simple structure, reliable compounding, high thermal efficiency, stable resistance performance of thermal fatigue, etc. The complex process of the invention is simple for application andis applicable to the use on an induction cooker.

Description

technical field [0001] The invention belongs to the field of cooking utensils and relates to an aluminum alloy die-casting pot with a composite bottom and a composite process thereof. Background technique [0002] At present, most of the composite-bottom die-casting pots that can be used in induction cookers are mechanically riveted composite-bottom pots. This kind of composite-bottom pot uses riveting nails to fix the stainless iron composite bottom sheet on the bottom of the pot body. The effective area of ​​the eddy current on the compound film is small, so the thermal efficiency is low; and there are defects such as complex manufacturing of molds and parts, and poor connection strength between the pot body and the film; the stainless iron compound film is uneven and long-term Using it will also cause damage to the surface of the induction cooker. In addition, there are some composite bottom die-casting pots that pre-process the connection structure on the stainless iron...

Problems solved by technology

[0002] At present, most of the composite-bottom die-casting pots that can be used in induction cookers are mechanically riveted composite-bottom pots. This kind of composite-bottom pot uses riveting nails to fix the stainless iron composite bottom sheet on the bottom of the pot body. The effective area of ​​the eddy current on the compound film is small, so the thermal efficiency is low; and there are defects such as complex manufacturing of molds and parts, and poor connection strength between the pot body and the film; the stainless iron compound film is uneven and long-term Use will also cause damage to the surface of the induction cooker

In addition, there are some composite bottom die-casting pots that pre-process the connection structure on the stainless iron bottom sheet. During die-casting, the connection structure is integrated with the pot body through die-casting, although it can better solve the problems of low thermal efficiency and insufficient flatness of the bottom sheet. , but there are still disadvantages such as complex manufacturing of molds and parts, high processing difficulty, and poor connection strength; especially during die-casting, the positioning reliability of the composite film in the die-casting mold is poor, which will lead to a high rate of waste and defective products. High consumption, so the production cost is not easy to control
