Embodiment Construction

[0015] The technical scheme of the present invention will be further described below in conjunction with specific examples:

[0016] A fishhook with a high specific gravity that can be injection molded with a tungsten head is characterized in that tungsten powder is used as a base material, polylactic acid and nylon are melted and blended, the fishhook is put into a mold, and finally the fishhook with a high specific gravity is injection molded. The parts by weight of each raw material are 90 parts of tungsten powder, 8 parts of nylon powder, and 5 parts of polylactic acid.

[0017] The preparation method comprises the following steps:

[0018] Mix tungsten powder and polylactic acid evenly, then add it to the molten nylon, mix evenly, inject it into the mold cavity with the fishhook, and cool it to shape.

[0019] The density of the counterweight material obtained is 10-13g / cm 3 .

[0020] The schematic diagram of the resulting high specific gravity tungsten head fishhook ...

Abstract

The invention discloses an injection molded tungsten fishhook with high specific gravity. According to the injection molded tungsten fishhook, tungsten powder is selected as the material of the main body of a counterweight; the tungsten powder is high in density and small in size, thereby improving the weight countering efficiency and being convenient to use; polylactic acid can be degraded, thereby being harmless to the environment; polyamide is taken as binding resin for tightly binding the counterweight with the fishhook, therefore the counterweight is not easy to fall off; the tungsten fishhook is molded by injection according to the shapes of various molds after the tungsten powder and the polyamide are mixed, thereby meeting different demands in weight counting; the tungsten fishhookdoes not pollute the environment, does no harm to a human body and can be degraded after being discarded, thereby being the best choice for replacing the fishing tool made of lead; the final productmade of the tungsten powder is more metallic in the texture and the tungsten powder has higher density, so that a fisherman feels more sensitive in hand feeling and the fish biting possibility is improved.

Description

technical field [0001] The invention belongs to the technical field of fishing tackle design, and in particular relates to a fishhook with a high specific gravity and a tungsten head that can be injection molded. Background technique [0002] Fishing is an outdoor activity that Chinese people have loved since ancient times. The main tools for fishing include fishing rods, hooks and baits. Perfect fishing tackle becomes a sharp weapon for fishing, and the hook is the key link. Now the development of fishhooks is very fast, there are many types, there are stainless steel, alloy steel with carbon materials, and there are many classifications of sizes and models. [0003] During the use of the fishhook, due to different water flow conditions and different environments, it is necessary to add a counterweight to the fishhook to adapt to the fishing environment. At the same time, a suitable counterweight is also more conducive to the feeling of throwing the line and pulling when f...
