Abstract

The invention discloses a burr removing knife used for injection products. The knife comprises a plastic handle (1) and a single-edge blade (2), wherein the plastic handle (1) is made from shock resistant polystyrene; the single-edge blade (2) is made from a high-carbon tool steel plate with thickness of 2-3mm; the main body width of the single-edge blade (2) is consistent; the front end of the single-edge blade (2) is cut into a bevelled edge and an inclined surface with an included angle alpha of 20-45 degrees is arranged along the whole bevelled edge, thus forming an edge part (2a) of the single-edge blade (2); the width of the tail end of the single-edge blade (2) gradually increases from front to back and the increments at the left and right sides are equal, thus forming a fishtail-shaped connecting part (2b); the fishtail-shaped connecting part (2b) is embedded in the plastic handle (1). The knife has long service life, is convenient to operate and can ensure smoothness of product surfaces when used for removing burrs and flashes of the injection products.

Description

technical field

[0001] The invention belongs to the technical field of cutting tools, and in particular relates to a cutting tool for removing burrs from injection molding products. Background technique

[0002] Plastic products using injection molding will leave some burrs and flashes after molding, which will affect the appearance of the product and need to be completely removed. The knives currently used for deburring and flashing are usually snap-off blades that can be used multiple times on the market. The blade is a double-edged blade, which is thin and cannot be used vertically, and the surface of the product is not smooth after deburring; the blade is long and inconvenient to operate, resulting in low production efficiency; although it can be broken and used many times, the overall life is not Long, the consumption of the blade is large, and the cost of use is high. Contents of the invention

[0003] In view of the above technical problems, the present invention ...

Embodiment Construction

[0017] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0018] Such as figure 1 As shown, a deburring knife for injection molding products consists of a plastic handle 1 and a single-edged blade 2.

[0019] The plastic knife handle 1 is made of impact-resistant polystyrene (HIPS), and the single-edged blade 2 is made of high-carbon tool steel plate with a thickness of 2-3mm. The material and thickness of the single-edged blade 2 have requirements, and the purpose is to improve the strength of the single-edged blade 2 .

[0020] The main body width of the single-edged blade 2 is consistent, and the front end of the single-edged blade 2 is cut into a hypotenuse, and along the entire hypotenuse, an inclined surface with an included angle α of 20 to 45° is provided (such as figure 2 Shown), thereby constituting the blade portion 2a of the single-edged blade 2. One side of the blade portion 2a is a slope and on...
