Hand tool multicolor handle manufacturing method

The present invention is related to a method of manufacturing a hand tool handle.

Press, the handle of the hand tool has a grip formed by plastic injection molding. In order to enhance the comfort of the grip, a plastic foam sleeve is arranged around the outer edge of the grip, in order to highlight the hand tool. The trademark brand, text or label of the handle, the inventor of the present invention developed a hand tool handle, as shown in Figures 1 and 2, which is an exploded view of the handle of the hand tool and a schematic diagram of the finished product, which mainly includes a grip 1, a cover 2, an elastic cover 3 and the like, wherein the cover 2 has a window 4 recessed inwardly at a side position, and a plurality of hollow slots 5 are provided at the front position, and the cover is filled The elastic coating layer 3 is used to express a pattern, so that the handle of the hand tool can have a two-color effect, and at the same time, the pattern is displayed to highlight the trademark or the label of the trademark brand.

However, in order to provide the characters or labels of various trademark brands on the handle of the hand tool, the mold of the cover body 2 must be formed for different trademarks, and the cover bodies 2 of different trademarks are formed, due to various hand tools and Corresponding to the size, shape and curvature of the cover, the cost of opening the mold will be greatly increased, and if more than two colors are to be provided, a plurality of filling holes and a filling tank must be further provided to infuse different colors. The raw material increases the manufacturing cost of the handle of the hand tool. In view of this, the inventor of this case has been carefully researched and developed, and has accumulated years of research and development experience in related instruments, and finally the invention was born.

The object of the present invention is to provide a method for manufacturing a multi-color handle of a hand tool, which is formed by inserting a replaceable sub-mold, thereby reducing the cost of mold opening, and forming a cover of different colors and holding on the handle of the hand tool. a hand tool that forms a multi-color handle.

In order to achieve the above object, the manufacturer of the multi-color handle of the hand tool provided by the present invention The method includes the steps of: forming a handle body: providing a first mold set, the first mold set having a first template and a second template, the first template being opposite to the second template, and The first template and the second template are selectively occluded to each other, and the first template and the second template are defined to form a handle body cavity. When the first template and the second template are in close contact, a handle material is poured into the handle body cavity to solidify the handle material to form a handle body; and the cover body step is: providing a second mold set, the second mold set having a third template, a fourth template and a number one a sub-mold, the third template and the fourth template can be mutually abutted to define a cover cavity, wherein the third template is provided with at least one first set of slots, and the number of the first sub-modules The first sub-mold has a first pattern surface, the first pattern surface has a first pattern, and the first template of the third template is a first pattern. The first sub-modules can be separately selected And the inner wall surface of the third template is in the same plane as the first pattern surface of the first sub-mold, and the first pattern is exposed, and a cover material is poured into the cavity of the cover body to make the cover body Forming a cover body, the cover system forming a layer with respect to the first pattern of the first pattern surface of the first sub-mold; completing the finished product step: providing a third mold set, the third mold set having a fifth a template and a sixth template, the fifth template and the sixth template can be mutually abutted to define a mold cavity, and then the cover body is coupled to the handle body and disposed in the mold cavity, A gripping material is poured into the mold cavity, and the grip portion is solidified to form a grip portion on the outer periphery of the handle body, and a third pattern is formed between the layers of the cap body to complete the finished product.

The method for manufacturing the multi-color handle of the hand tool provided by the present invention is characterized in that the first sub-mold is selected through the first set of slots of the third template, and the cover body having different patterns can be poured and molded to reduce the opening. The mold cost, and the cover material of different colors and the material of the grip portion can be reused, and the cover body and the grip portion of different colors are formed on the handle body, thereby forming a hand tool having a multi-color handle.
