Die-casting mould and preparation method of die-casting product thereof

Abstract

The present invention belongs to a pressure-casting die and a method of manufacturing a die-casting product. The present invention comprises a die blank, a back mold body, a front mold body and a supporting column. A heating plate is arranged in the die blank. The supporting column is arranged under a lower part of the die blank. An electromagnetic boiler mold is arranged in the front mold body. A heating plate is arranged on the electromagnetic boiler mold. An electromagnet core is arranged on the heating plate. A solenoid coil is arranged on the electromagnet core. A non-electromagnet steel ring is arranged between the solenoid coil and the heating plate. The electromagnet core is fixed on the die blank by a double-screw bolt. The electromagnet core is provided with a cold air blast intake. The advantage of the present invention is that an aluminum alloy boiler bottom is additionally provided with a steel plate, which enlarges use range of the aluminum alloy boiler. As the steel plate is better than the aluminum alloy in strength, abrasion resistance of the boiler bottom is improved. Fusion method is adopted for the boiler bottom and the steel plate of the present invention, which is easy to make an aluminum alloy boiler body connected with the steel plate in the process of manufacturing the aluminum alloy boiler body. Therefore, manufacture technique of the present invention is very simple and the present invention has future market potential.

Description

technical field [0001] The invention belongs to a die-casting mold and a method for making die-casting products. Background technique [0002] Aluminum alloy is one of the commonly used materials for making pots, but because aluminum alloy is an "insulator" in the electromagnetic field, ordinary aluminum alloy pots cannot be used on induction cookers, which limits its use. Known from the search, the pot body of a general electromagnetic cooker, the main pot is usually made of non-ferromagnetic materials such as aluminum, copper, etc., and the heating plate is made of ferromagnetic material, which is pressure-welded on the bottom of the pot body. However, when the above-mentioned pan is actually used, the workload on the pan is thermally cycled due to the heating and cooling process. According to the general pressure welding method, the pressure welding strength cannot withstand the effect of thermal cycle work load, so the heating element plate may peel off from the main po...

Problems solved by technology

According to the general pressure welding method, the pressure welding strength cannot withstand the effect of thermal cycle work load, so the heating element plate may peel off from the main pot body at the pressure welding interface

In addition, when the heating element plate is bonded to the main pot body by thermosolid phase bonding, the heating element plate may peel off during the temperature drop of the finished pot body
