External plastic packaging tool handle and manufacturing process thereof

Abstract

The invention provides an external plastic covering tool handle, comprising a wood handle body, wherein an outer plastic covering layer which is integrally cast and molded with the handle body is covered outside the handle body. A manufacturing process comprises the steps of wrapping the handle body and the outer plastic covering layer into an integral structure; placing a selected mould into an injection molding machine and placing one end of the handle body into a mould cavity to be clamped; applying pressure to a sticky-flow-state raw material and injecting into the mould cavity; and cooling and opening the mould to take out a product. The external plastic covering tool handle is simple in structure; an external plastic covering layer is cast at the connecting end of the tool handle and tool connecting pants, and the shape of the external plastic covering layer layer is changed to meet the pant diameter structure of the tool connecting pants with different specifications, so that the use is convenient; and only a traditional handle needs to be simply machined, so that woods are saved, and the manufacturing cost is reduced, and the service life of the handle is prolonged; and the process for manufacturing the external plastic covering tool handle is simple and has wide applicable range so as to be suitable for large-batch industrial production.

Description

technical field [0001] The invention relates to a tool handle, in particular to a tool handle which is provided with an outer plastic layer at the connection section between the handle body and the tool connecting trousers, and the manufacturing process of the handle. Background technique [0002] Most of the handles for assembled products currently on the market use wood as the raw material in the production process. After processing by mechanical equipment, the diameter meets the requirements and then assembled with the product to form a handle for hand tools. Because tool handles made of metal are heavy and inconvenient to use, general tool handles use wood as raw materials, and because the handles are easily damaged after long-term use, the replacement frequency is high, which will cause a large number of trees to be felled. And some tools, due to the greater force required during use, require greater strength at the connection between the tool connecting pants and the t...

AI Technical Summary

Problems solved by technology

Because metal tool handles are heavy and inconvenient to use, general tool handles use wood as raw materials, and because the handles are easily damaged after long-term use, the frequency of replacement is high, which will lead to a large number of trees being felled

And some tools, due to the greater force required during use, require greater strength at the connection between the tool connecting pants and the tool handle, so the trouser diameter of the tool connecting trousers is larger or has a taper, such as steel picks, their trouser diameters are as follows: Taper, the outer diameter of one end needs to be larger than the outer diameter of the traditional handle, so that the wood material required to make the handle is thicker. After processing, one end of the handle is processed into a tapered trouser diameter, etc., while the other end is still traditional. The thickness of the handle

In this way, it is not only an absolute waste of tree resources to cut down a large number of thicker trees just to meet the needs of the tapered trouser diameter at one end, but also increases the cost price of wooden handle raw materials, which brings a lot of confusion to manufacturers.
