Description
Technical Field
The utility model relates to an abrasive paper presss from both sides, especially relates to an abrasive paper clamp of circular cone type.
Background
In the manufacturing process of the plastic mold, the conical runner glue inlet and other round holes are usually formed by spark machining, the surface smoothness of the mold hole processed by the spark machine is not good enough, and in order to achieve a better demolding effect when the mold is opened, the runner glue inlet and the round holes need to be polished and the like. In the existing industry, various hole-type structures of a die are generally formed by fixedly mounting abrasive paper on a chuck of a grinding machine, and the grinding machine drives the abrasive paper to rotate and polish.
A clamp head of the grinding machine and the abrasive paper are fixedly installed through an abrasive paper clamp, please refer to fig. 1, which is a conventional cylindrical abrasive paper clamp structure, one end of the abrasive paper is inserted into a notch of the abrasive paper clamp, and after the abrasive paper is wound along the abrasive paper clamp, the abrasive paper is fixed on the abrasive paper clamp through adhesive paper; and then fixedly installing the abrasive paper clamp on a clamp head of the grinding machine, correspondingly inserting the abrasive paper into the hole-shaped structure of the die, and starting the grinding machine to polish. If the diameter of the cylinder of the abrasive paper clamp is smaller than 2mm, the thickness of the corresponding notch is reduced, and the load born by the root of the notch in the polishing process is reduced, so that the notch of the abrasive paper clamp is easy to break. Therefore, the existing cylindrical abrasive paper clamps can not polish holes with the diameter less than 2.5 mm.
Therefore, it is an urgent technical problem to be solved in the art how to provide a sandpaper clip capable of polishing small plastic mold holes.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a circular cone sand paper clamp to the unable scheduling problem of handling of less plastic mould hole polishing that above-mentioned prior art exists.
The utility model adopts the technical proposal that: the conical sand paper clamp comprises a cylindrical clamping rod, wherein one end of the clamping rod is a truncated conical chuck, an opening is formed in the end of the chuck, the opening width of the opening is 0.3mm, and the depth of the opening is larger than the conical height of the chuck.
Preferably, the diameter of the conical large opening of the chuck is 3mm or 4 mm.
Preferably, the clamping bar has a cylindrical diameter of 2.35mm, 3mm or 4 mm.
Preferably, a section of cylindrical connecting rod is arranged between the chuck and the clamping rod with the diameter of 2.35mm, and the diameter of the connecting rod is equal to the diameter of the conical large opening of the chuck.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model provides a circular cone abrasive paper presss from both sides, in order to solve the problem that less plastic mould hole can not be thrown, improves into circular cone chuck with current cylindrical chuck, and the abrasive paper clamp after the improvement can all carry out polishing treatment to the plastic mould hole that the diameter is little to 1mm, has had great improvement to prior art. And according to different plastic mould aperture sizes, the abrasive paper clips with different tapers are produced in a standardized manner, so that the popularization and application of the conical abrasive paper clips can be realized, the processing of the individual abrasive paper clips is not needed, and the production efficiency of the plastic mould can be correspondingly improved.
Drawings
FIG. 1 is a schematic diagram of a prior art structure;
fig. 2 is a schematic structural diagram of an embodiment of the present invention;
fig. 3 is a schematic structural diagram of another embodiment of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
Referring to fig. 2 to 3, the present invention relates to a conical sandpaper clip, which comprises a cylindrical clamping rod 1, wherein one end of the clamping rod 1 is a truncated cone-shaped chuck 2, and a gap 3 is opened at the end of the chuck 2. In order to meet the standardized production and application, the diameter of the clamping rod 1 is generally divided into 2.35mm, 3mm, 4mm and the like.
Example 1: when the cylindrical diameter of the clamping rod 1 is 3mm or 4mm, the diameter R of the conical large opening of the chuck 21The diameter of the cylinder of the clamping bar 1 is the same. The opening width of the gap 3 is 0.3mm, and the depth is greater than the conical height H of the chuck 21This is to ensure the thickness of the root of the notch 3 and prevent the occurrence of fracture.
Example 2: when the cylindrical diameter of the clamping rod 1 is 2.35mm, the diameter R of the conical large opening of the chuck 21Is larger than the diameter of the cylinder of the clamping rod 1 and the diameter R of the big conical opening of the chuck 21Also divided into two sizes, 3mm and 4 mm. A section of cylindrical connecting rod 4 is arranged between the clamping rod 1 and the chuck 2, and the cylindrical diameter of the connecting rod 4 is equal to the diameter R of the conical large opening of the chuck 21. Gap 3Has an opening width of 0.3mm and a depth greater than the conical height H of the chuck 21This is to ensure the thickness of the root of the notch 3 and prevent the occurrence of fracture.
Hole depth H of plastic mould hole2Relative to the hole diameter R2The size of the sand paper clamp is much smaller, so that the conical sand paper clamp can polish the conical flow channel glue inlet and other round holes and meets the following conditions:
wherein,R 1 the diameter of the conical large mouth of the chuck 2,H 1 the conical height of the collet 2 is such that,R 2 the diameter of the plastic mold hole is greater than the diameter of the plastic mold hole,H 2 the hole depth of the plastic mold hole.
When the adhesive tape is used, one end of the cut strip-shaped abrasive paper is inserted into the notch 3 of the abrasive paper clip, and the abrasive paper is adhered to the abrasive paper clip by using adhesive paper after being wound along the abrasive paper clip; then the sand paper clamp is fixedly arranged on the clamp head of the grinding machine, and the grinding machine is started for polishing.
The above embodiments are only used to illustrate the structure of the present invention, and those skilled in the art can make various modifications and changes under the concept of the present invention, and these modifications and changes are all included in the protection scope of the present invention.
