Embodiment 1

[0039] The technical scheme adopted in the present invention is as follows: a small-sized engraving saw blade hot-pressing mold, including an engraving saw blade 1, a mold frame assembly 2, and a hot-pressing mold assembly 3 used in conjunction with the mold frame assembly 2, the hot-pressing mold assembly 3 includes a baffle assembly 4 made of high-strength graphite material, a baffle assembly 5 used in conjunction with the baffle assembly 4, and a central rod 6. The baffle assembly 4 includes a first side baffle 7 and a second side The baffle 8, at least one middle baffle 9, the front baffle 10 and the rear baffle 11, each side of the first side baffle 7 and the second side baffle 8 is provided with at least two symmetrical The first groove 12, the two sides of the middle baffle plate 9 are respectively provided with the second groove 13 corresponding to the first groove 12, the corresponding first groove 12 and the second groove 13 It is combined into a housing cavity 14 fo...

Embodiment 2

[0042] On the basis of Example 1, the shortest distance between adjacent first grooves 12 is 4-8 mm, and the distance between each adjacent second groove 13 is 4-8 mm. The shortest distance between the first groove 12 and the other side of the first side baffle 7 is 4-9 mm. This avoids a reduction in the quality of the engraving saw blade 1 due to mutual influence between the engraving saw blades 1 during the sintering process.

Embodiment 3

[0044] On the basis of Example 2, the shortest distance between adjacent first grooves 12 is 6 mm, and the distance between each adjacent second groove 13 is 6 mm. The shortest distance between the groove 12 and the other side of the first side baffle 7 is 7mm. The quality of the engraving saw blade 1 sintered out like this is the best.

Abstract

The invention discloses a hot-pressing mold for small-sized carving saw blades. The hot-pressing die comprises the carving saw blades, a mold frame assembly and a hot-pressing mold assembly used in cooperation with the mold frame assembly; and the hot-pressing mold assembly comprises a baffle plate assembly, separation plate assemblies and center rods, wherein the baffle plate assembly is made ofa high-strength graphite material, and the separation plate assemblies and the center rods are used in cooperation with the baffle plate assembly. According to the hot-pressing mold, the mold frame assembly with the carving saw blades and made of the high-strength graphite material, the hot-pressing mold assemblies and the center rods are assembled together, and are put into a vacuum hot-pressingsintering machine to be subjected hot-pressing sintering so that high-pressure sintering of the stone carving saw blades can be realized, and therefore single sintering time is shortened, the production speed is increased, and the product quality is improved.

Description

technical field [0001] The invention belongs to a diamond engraving saw blade, in particular to a small-sized engraving saw blade hot-pressing mold. Background technique [0002] Small size (outer diameter 20-60mm) diamond engraving saw blades are usually used for engraving or engraving on stone, ceramics, and concrete. Traditional engraving saw blades are usually sintered in a bell furnace after cold pressing. Limited by equipment, they cannot be sintered at high pressure. Although the output of one furnace is large, the sintering time is long, up to 6 hours, and there are many defective products, especially for saw blades. The accuracy of the shape and size of the blade cannot be guaranteed, and the quality and performance of the engraving saw blade is not high. Contents of the invention [0003] The purpose of the present invention is to solve the phenomenon that the above-mentioned engraving saw blades are usually sintered in a bell furnace after cold pressing, which ...
