Manufacturing method of glove mould for dipping wire

- Jul 13, 2020-

Background technique:

Current impregnated wire glove mold fixtures generally include nuts, end caps, bushings, jackets, T-bolts, rolling bearings, circlips, compression springs, cushions, nuts, end covers, bushings, jackets, and T-bolts. Made of stainless steel, in order to reduce the friction between the bushing and the jacket, the rolling bearing must also be increased, so the existing impregnated glove mold clamp has the following disadvantages. 1. Because most of the parts are made of stainless steel, the process Complicated, so the production cost is high; 2. In order to prevent the nut and the T-bolt threaded connection from loosening during production operation, it is necessary to add a compression spring, which brings difficulties and safety hazards when installing and removing the mold. A production line Thousands of sets of glove molds for dipping lines need to be installed, so it takes a long time, and the labor intensity is large, which affects the production efficiency; 3. Since the rolling bearing needs to be added with lubricating oil after a period of use, the bearing must be oiled regularly. Maintenance, which consumes a lot of oil, and the lubricant often overflows, which affects the quality of the product; 4. Because most of the parts are made of stainless steel, the mold fixture is heavy and consumes a lot of energy; 5. The spring force of the spring needs to be overcome during installation, so the labor intensity is large and there are hidden safety risks.

 

Utility model content:

Based on the deficiencies of the prior art, the purpose of the present invention is to provide a dipping wire glove mold fixture with low manufacturing cost, low energy consumption, convenient and quick installation, low labor intensity, flexible rotation, long service life and safety. In order to achieve the above object, the utility model provides a dipping wire glove mold fixture, which includes a nut, an anti-loosening pad, an end cover, a shaft sleeve, a clamping sleeve, a cushion pad, a T-shaped bolt, the nut, the end cover, and the shaft The sleeve, jacket, T-shaped bolt, etc. are mainly made of engineering plastic. The cushion pad and jacket are successively fitted on the flat end cylindrical surface of the glove mold fixture. The T-shaped bolt T-shaped end is inserted into the glove mold slot and rotated 90 degrees after T The elastic piece in the square convex block at the shape end is fastened in the glove mold slot, the sleeve is sleeved on the outer circumference of the sleeve, and the threaded end of the T-shaped bolt passes through the cushion pad, the sleeve, the sleeve and the end cover 1. After the anti-loosening pad is screwed on the nut. As an embodiment of the present invention, the contact end surface of the end cover and the sleeve has a plurality of uniformly distributed arc-shaped protrusions, and the plurality of equal arc-shaped protrusions makes the end cover and the sleeve contact end surface in line contact . As an embodiment of the present invention, the contact circumferential surface of the sleeve and the jacket has a plurality of uniformly distributed arc-shaped convex strips, and the equivalent uniformly distributed convex strips make the circumferential surface of the sleeve and the jacket in contact form a line In contact, the end of the shaft sleeve in contact with the jacket has a plurality of uniformly distributed arc-shaped protrusions, and the plurality of equivalently distributed arc-shaped protrusions makes the shaft sleeve and the contact surface of the jacket in line contact. As an embodiment of the present invention, the threads of the nut and the T-shaped bolt are multi-start threads. As an embodiment of the present invention, one end of the sleeve has two lugs symmetrically arranged on both sides. The two lugs are integrally formed with the sleeve, and the two lugs have through holes. The center line of the two through holes mentioned above does not pass through the axis line of the sleeve.

The utility model has the following beneficial effects:

  1. Because most of the parts are made of engineering plastics, which can be injection molded, the process is simple, so the manufacturing cost of the mold fixture is greatly reduced;

  2. Because the rubber 0 type ring is used as an anti-loosening part, when the nut is tightened, the 0 type ring is It is embedded in the thread groove under pressure, so as to always play the function of buckle and expansion between the thread, and to ensure that the entire set of mold fixtures will not be loose during long-term production operation, which can achieve the long-term production safety goal of zero accidents And it is very easy to install the mold fixture, which greatly saves the time of installing the fixture and thus improves the production efficiency;

  3. Owing to the omission of the rolling bearing, there is no need to add lubricating oil for long-term use, so that there will be no overflow of lubricating oil In the future, the situation that affected the quality of the product occurred, and at the same time, zero maintenance was achieved;

  4. Since the main parts are made of engineering plastics, it has corrosion resistance, wear resistance, high temperature resistance, self-lubrication, light weight, high strength, and elasticity. , Can be injection molded and other comprehensive characteristics, so it is safe and reliable to use; extend the service life; save energy and reduce consumption, low production cost,

  5. Because the contact circumferential surface of the sleeve and the jacket has multiple equal arc-shaped convex strips, the convex The strip makes the circumferential surface of the contact surface of the bushing and the jacket in line contact, so that even if there are dust or small particles in the contact surface of the bushing and the jacket, the relative rotation between the bushing and the jacket will not be affected.
