Description

Cutter for processing plastic material water gap

Technical Field

The utility model relates to a processing cutter especially relates to a cutter at processing plastic material mouth of a river.

Background

The nozzle is a joint between a frame and a part formed when a model is cast in a factory. Also called "soup mouth", means the inlet and outlet for the flow of the material in the heat-liquefied state. After the injection molding is completed, a cutting tool is usually used to cut the nozzle position of the plastic product, so as to polish off the formed part of the nozzle.

However, the existing nozzle machining tool is of a single-blade structure, the cutting frequency of the blade reaches about 10 ten thousand times, the blade is broken, the service life is short, and a user needs to frequently replace the tool, so that inconvenience is caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses technical scheme is to above-mentioned condition, and in order to solve above-mentioned problem and provide a cutter at processing plastic material mouth of a river, the cutter includes: the main knife is provided with a knife edge section and a connecting section, the knife edge of the main knife is positioned at the bottom of the front end of the knife edge section, the connecting section is fixed with the knife handle, the knife edge section is positioned between the two auxiliary knives, the knife edge of the main knife is lower than the bottom of the auxiliary knives, and the length of the auxiliary knives is greater than that of the knife edge section.

Further, the bottom of the front end of the auxiliary knife is also provided with a fillet.

Further, the length of the auxiliary knife is 11-13mm, and the length of the knife edge section is 7-9 mm.

Further, the cutting angle theta of the cutting edge is 30-60 degrees.

Further, the height of the main knife is 7-9mm, the height of the auxiliary knife is 4-6mm, and the height of the knife handle is 6-8 mm.

Further, the bottom of the secondary knife is aligned with the bottom of the handle, and the top of the primary knife is aligned with the top of the handle.

After the technical scheme is adopted, the utility model discloses an effect is: the cutter with the structure can ensure that the main cutter is not easy to break under the condition that the auxiliary cutter bears a part of pressure, thereby greatly prolonging the service life. Through tests, the cutter can cut 30-50 ten thousand times, a user does not need to change the cutter frequently, and labor and time cost are saved.

Detailed Description

It is specifically noted that the terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, and the like in a specific posture, and if the specific posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described below by way of examples:

the utility model provides a cutter at processing plastic material mouth of a river, it is shown with combination fig. 1-3, the cutter includes: the utility model provides a sword, the sword is including main sword 1, two vice sword 2 and handle of a knife 3, two vice sword 2 are all protruding from the front end of handle of a knife 3, main sword 1 has sword section 11 and linkage segment 12, the cutting edge 10 of main sword 1 is located the bottom of sword section 11 front end, linkage segment 12 forms fixedly with handle of a knife 3, sword section 11 is located between two vice sword 2 to the cutting edge 10 of main sword 1 is less than the bottom of vice sword 2, the length of vice sword 2 is greater than the length of sword section 11. When cutting operation is carried out, the cutter handle 3 is inserted into cutting equipment, the main cutter 1 is aligned with the position of a water gap of a product and cuts the part formed by the water gap, the auxiliary cutter 2 is attached to the surface of the product, and the auxiliary cutter 2 can bear pressure generated during cutting, so that the main cutter 1 is not easy to break, and the service life is prolonged.

Specifically, the length of the secondary knife 2 is 11-13mm, and the length of the blade section 11 is 7-9 mm. The length of the auxiliary cutter 2 is prevented from being too long, and effective cutting of the main cutter 1 can be guaranteed.

Specifically, the cutting angle θ of the cutting edge 10 is 30 to 60 °. The blades 10 with different blade angles theta can be adopted according to the nozzle parts with different shapes so as to adjust the cutting force.

Specifically, the height of the main knife 1 is 7-9mm, the height of the auxiliary knife 2 is 4-6mm, and the height of the knife handle 3 is 6-8 mm. More specifically, the bottom of the secondary knife 2 is aligned with the bottom of the shank 3 and the top of the primary knife 1 is aligned with the top of the shank 3.

Preferably, the bottom of the front end of the counter knife 2 is also provided with a rounded corner 20. The fillet 20 can be smoother when the auxiliary knife 2 moves, so that abrasion is avoided, and the service life is further prolonged.

Therefore, the cutter with the structure can ensure that the main cutter is not easy to break under the condition that the auxiliary cutter bears a part of pressure, thereby greatly prolonging the service life. Through tests, the cutter can cut 30-50 ten thousand times, a user does not need to change the cutter frequently, and labor and time cost are saved.

The above-mentioned embodiments are merely preferred examples of the present invention, and do not limit the scope of the present invention, so all equivalent changes or modifications made by the structure, features and principles of the present invention should be included in the claims of the present invention.
