Hollowed-out craft door handle and manufacturing method thereof

Abstract

The invention discloses a hollowed-out craft door handle and a manufacturing method thereof. The hollowed-out craft door handle structurally comprises a door handle body; the door handle takes the shape of a hollow tube; and a hollowed-out decorative hole is formed on the surface of the door handle. The manufacturing method comprises the following steps of: firstly designing pattern-text flat surfaces of the door handle to be manufactured and a hollowed-out part, then carrying out mechanical engraving by using resins instead of woods, and engraving template samples; placing two layers of adhesive films between mould frames, and respectively arranging an upper cover and a lower cover above and under the mould frames; burying the manufactured templates in the middle of the mould cavities, subjecting the templates to vulcanization to form a mold and opening a casting runner; then placing the mould in a centrifugal casting machine, switching a power supply on, pouring molten zinc, throwing the molten zinc into mold cavities to encase a loose core, and after 30 seconds, taking out the mould and extracting out the loose core to form a hollowed-out product, wherein the hollowed-out product is a blank product; and finally burring, polishing and electroplating the hollowed-out product to form the hollowed-out craft door handle. According to the hollowed-out craft door handle and the manufacturing method thereof, materials are saved, and the strength of the hollowed-out craft door handle is not reduced on the basis that the hollowed-out craft door handle has the decorative effect; and the manufacturing method of the hollowed-out craft door handle is simple and convenient and is suitable for volume production, thereby reducing the production cost.

Description

technical field [0001] The invention relates to a door handle, in particular to a hollow-out door handle and a manufacturing method thereof. Background technique [0002] In the market, there are all kinds of door handles. Whether it is in terms of material, structure, or function, most of them are solid structures, which have many shortcomings. Even some craft door handles are either just hollow structures. , or surface printing or other beautiful color patterns, but they have not solved any technical problems. The technical problem we need to solve is to save materials without reducing its strength on the basis of beauty and decoration. Some functional parts Can be concentrated in the hollow tube of the door handle. [0003] Here we introduce a hollow door handle with hollow holes on the surface, so we must introduce the manufacturing method of this kind of door handle. However, the method of making hollow door handles is still blank at present, especially it has not been...

[0002] In the market, there are all kinds of door handles. Whether it is in terms of material, structure, or function, most of them are solid structures, which have many shortcomings. Even some craft door handles are either just hollow structures. , or surface printing or other beautiful color patterns, but they have not solved any technical problems. The technical problem we need to solve is to save materials without reducing its strength on the basis of beauty and decoration. Some functional parts Can be concentrated in the hollow tube of the door handle

[0003] Here we introduce a hollow door handle with hollow holes on the surface, so we must introduce the manufacturing method of this kind of door handle. However, the method of making hollow door handles is still blank at present, especially it has not been used yet. Industrial methods are produced in batches, so the cost of production will be high
