Embodiment Construction
[0017] The overall size of the heating element of the iron is reduced by 5-8mm. Three sets of molds are used for die casting respectively, that is, the cover 1, the heating body vaporization chamber 2, and the triangular plate 3 with the steam outlet channel are respectively die cast; Three pieces of iron heating element in one. Fixing can adopt the mode of welding machine spot welding or other feasible ways; Finally, another set of fourth set of molds with the original size and shape of the heating element of the iron is used to put the fixed bottom slab 4 into the fourth set of molds, and add The melted aluminum water wraps the three-in-one heating element of the iron together and integrates it into the final bottom plate 5, which is the heating element of the iron.

The invention provides a method for manufacturing a hollow flatiron heating unit, comprising the following steps: die casting three parts of a cover, a heating unit vaporization chamber and a vapor discharging channel in triangular plate shape by using three sets of moulds, and fixedly connecting the three parts together to combine into a base slab which whole dimension is smaller than the dimension of the flatiron heating unit; the base slab is covered by molten aluminum pad within a fourth set of mould to obtain the flatiron heating unit. Accordingly, whole dimension of the base slab is smaller than the dimension of the flatiron heating unit to 5-8mm. After forming by the fourth set of mould, the flatiron heating unit will neither leak air nor burn out a heating tube caused by uneven heating of the heating tube since the heating tube is not completely covered by aluminum. Meanwhile, disability rate for manufacturing the flatiron heating unit will not exceed 3%, and problems of the flatiron heating unit produced by pouring in prior art that an empty core has sands inside which are difficult to remove, or while the removing is not completely achieved, the sands will be taken out along with the vapour to burn out fabrics after heating of the flatiron heating unit are solved in the invention.
Description
technical field [0001] The invention belongs to a manufacturing method of a hollow iron heating body. Background technique [0002] There are usually two manufacturing methods for the heating element of the existing electric iron: [0003] One is casting. Because the heating body vaporization chamber of the iron and the triangular plate with the steam outlet channel are hollow, the heating pipe must be cast in the aluminum part, and the heating pipe cannot be exposed outside the heating body and the inside of the vaporization chamber. If the heating tube is not completely covered by the aluminum parts, it will lead to uneven heat dissipation of the heating tube, and at the same time, steam and water will quickly corrode the heating tube, which will directly affect the life of the heating tube. Therefore, in order to cast qualified heating parts, the scrap rate reaches 30% to 40%. [0004] The second is die casting. Since the heating body vaporization chamber of the iron ...
