Embodiment 1

[0032] Such as figure 1 As shown, the thermoforming mold of this embodiment includes a detachable upper mold and a lower mold, wherein the upper mold includes a sleeve 1, a pressure ring 9 and an upper core type 10, and the lower mold includes a die sleeve 2 and a mandrel 4 , the lower template 5, the lower core type 6, the pecking plate 7 and the upper template 8. The core type of this embodiment includes a mandrel 4 and upper and lower core types 10,6. The mold case 2 is cylindrical, with a taper on the inner wall, which shrinks outward from bottom to top; when hot pressing, the big end of the mold case 2 faces upwards (that is, the end with the larger diameter of the inner wall of the mold case 2 faces upwards), and on the top of the die case 1 A socket 1 is installed, and a pad iron is placed under the mold sleeve 2; the lower template 5 is located at the bottom of the mold sleeve 2, and the outer surface of the mandrel 4 has a taper, which shrinks from bottom to top inwa...

Embodiment 2

[0035] Such as image 3 As shown, the thermoforming mold of this embodiment includes a detachable upper mold and a lower mold, wherein the upper mold includes a sleeve 1, a pressure ring 9 and an upper connecting mandrel 12, and the lower mold includes a die sleeve 2, a lower connecting core Rod 13, lower template 5, pecking plate 7 and upper template 8. In this embodiment, the grinding stone is a cylindrical grinding wheel, and the core is a cylindrical mandrel structure. The mandrel is divided into an upper mandrel 12 and a lower mandrel 13 which are hollow inside. The mold case 2 is cylindrical, with a taper on the inner wall, which shrinks outward from bottom to top; when hot pressing, the big end of the mold case 2 faces upwards (that is, the end with the larger diameter of the inner wall of the mold case 2 faces upwards), and on the top of the die case 1 Sleeve 1 is installed, and a shim iron is placed under the mold sleeve 2; the lower formwork 5 is located at the bott...

Abstract

The invention relates to a grindstone hot press molding die and a hot press molding technology thereof. The die comprises an upper die and a lower die which can be separated. The lower die is on the bottom in a die sleeve. A core mold and a mandril are combined with a lower mold plate. A space for holding a hot-press workpiece blank is formed among the inner walls of the die sleeve. An upper mold plate is on the upper part in the die sleeve, and is placed on the blank of the hot-press workpiece. The lower surface of the upper mold plate is provided with a peck plate. A connecting sleeve and an upper connecting core mold are respectively combined with the die sleeve and the core mold. The upper mold plate and a pressing ring are placed between the connecting sleeve and the upper connecting core mold. The technology comprises: assembling the upper die and the lower die, installing the lower mold plate, installing the mandril, combining the core molds, putting into a blank to strike off a comb material, adding the upper mold plate and the pressing ring, performing prepressing, removing a sizing block, the connecting sleeve, the upper connecting core mold, and the pressing ring, and starting pressing; maintaining pressure, deflating, and repressing to complete pressing, and then unloading the die, and transferring a hot press workpiece blank on a drying rack. The grindstone hot press molding die is characterized by simple structure, easy operation, fast die heat conduction, even heated, and low heat energy loss.

Description

technical field [0001] The invention relates to a production and processing mold for forming hot-pressed abrasive blanks, in particular to a millstone hot-press forming die and its hot-press forming process. Background technique [0002] Because the special grinding stone (grinding wheel) for grinding the steel rail formed by hot pressing is formed by the original model, the hardness of the grinding stone is high, and it is very difficult to process the working surface of the grinding stone, and even the flat grinding process cannot be done. The purpose of processing is to sharpen the whetstone to facilitate the whetstone grinding operation; otherwise, the whetstone cannot be installed and used. [0003] The mold for millstone forming must be manufactured according to the design requirements of the mold during design, including: [0004] 1. The mold structure should conform to the shape and size of the grinding stone product; [0005] 2. The mold structure is easy to assem...
