Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass fiber grinding wheel mold technology, specifically a forming mold for glass fiber grinding wheel processing. Background Technology
[0002] Fiberglass grinding wheels are resin grinding wheels with fiberglass as the reinforcing material. They have high strength, heat resistance and impact resistance, and are widely used in metal processing, stone cutting, building materials and other fields.
[0003] Fiberglass grinding wheels are typically manufactured using a molding die. Fiberglass mesh sheets, resin, abrasive filler, and another fiberglass mesh sheet on one side are sequentially placed into the die groove. The grinding wheel is then produced through a series of processes including heating, pressing, and cooling. Currently, the molding dies used for fiberglass grinding wheel processing are generally custom-made, with a fixed die groove depth. When the thickness of the fiberglass grinding wheel varies, the die must be changed, leading to increased production costs. Therefore, an improved technology is urgently needed to address this problem in the existing technology. Utility Model Content
[0004] The purpose of this invention is to provide a molding die for processing glass fiber grinding wheels, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a forming mold for processing glass fiber grinding wheels, comprising a template, a mold cylinder, and a central positioning rod. The template has several circular grooves on its upper surface. A screw is vertically positioned at the center of each circular groove. The central positioning rod is threadedly connected to the screw. Several mold cylinders are inserted into the circular grooves. Circular blocks and circular washers are also provided within the circular grooves. The circular washers are supported on the upper surface of the circular blocks. The top of the central positioning rod is conical. A pressure plate is also provided around the central positioning rod, pressing against the upper surface of the circular washers. Through holes are provided at the center of each circular block and circular washer. The central positioning rod passes through the through holes at the center of each circular block and circular washer. The circular blocks and circular washers are also located inside the mold cylinder.
[0006] Preferably, the present invention provides a forming mold for processing glass fiber grinding wheels, wherein the outer surface of the mold cylinder is provided with a plurality of annular grooves along the circumferential direction.
[0007] Preferably, the molding die for processing glass fiber grinding wheels provided by this utility model has bevels at both ends of the inner wall of the die cylinder.
[0008] Preferably, the present invention provides a forming mold for processing glass fiber grinding wheels, wherein the outer diameter of the mold cylinder is consistent with the inner diameter of the circular groove.
[0009] Preferably, the molding die for processing glass fiber grinding wheels provided by this utility model has several grooves formed around the outer periphery of the circular groove.
[0010] Preferably, the present invention provides a forming mold for processing glass fiber grinding wheels, wherein the bottom of the central positioning rod is provided with a screw hole, and the central positioning rod is fastened to the screw rod through the screw hole.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] A screw is positioned at the center of the circular groove of the template. A circular pad and a circular washer are placed inside the circular groove. A central positioning rod is fastened to the screw through a screw hole. A pressure plate is set around the central positioning rod, pressing it onto the circular pad and circular washer. Compared with an integrated glass fiber grinding wheel forming mold, this structure facilitates the replacement of the circular pad and circular washer. Furthermore, different thicknesses of circular pads, circular washers, and central positioning rods with matching pressure plate heights can be selected according to different thicknesses, greatly improving flexibility and applicability, thereby reducing the cost of producing glass fiber grinding wheels of different thicknesses.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a forming mold for processing glass fiber grinding wheels, including a template 1, a mold cylinder 2, and a central positioning rod 3. The upper surface of the template 1 has several circular grooves 4, and the template 1 also has several recesses 10 around the circular grooves 4, so that when the mold cylinder 2 is difficult to remove, a tool can be inserted into the recesses 10 to lift the mold cylinder 2. A screw 5 is vertically arranged at the center of each circular groove 4 on the template 1. The central positioning rod 3 is threadedly connected to the screw 5, and a screw hole is opened at the bottom of the central positioning rod 3. The central positioning rod 3 is fastened to the screw 5 through the screw hole to realize the connection and disassembly of the central positioning rod 3 and the screw 5. Several mold cylinders 2 are respectively inserted into the circular grooves 4, and the outer diameter of the mold cylinder 2 is consistent with the inner diameter of the circular groove 4 to ensure the placement of the mold cylinder 2. To ensure stability inside the circular groove 4, several annular grooves 9 are provided on the outer surface of the mold cylinder 2 along the circumferential direction. The annular grooves 9 facilitate gripping of the mold cylinder 2, making it easy to remove the mold cylinder 2 from the circular groove 4. Circular pads 6 and circular gaskets 7 are also provided inside the circular groove 4. The circular gaskets 7 are supported on the upper surface of the circular pads 6. The top of the central positioning rod 3 is conical, and a pressure plate 8 is provided around the central positioning rod 3. The pressure plate 8 presses against the upper surface of the circular gaskets 7. Through holes are provided at the center of both the circular pads 6 and the circular gaskets 7. The central positioning rod 3 passes through the through holes at the center of the circular pads 6 and the circular gaskets 7. The circular pads 6 and the circular gaskets 7 are also provided inside the mold cylinder 2. Both ends of the inner wall of the mold cylinder 2 are beveled to facilitate the placement of the circular fiberglass mesh into the mold cylinder 2.
[0021] Usage and Principle: A template 1, a mold cylinder 2, and a central positioning rod 3 are prepared. A screw 5 is pre-installed at the center of the circular groove 4 on the upper surface of the template 1. Then, the through holes of the corresponding circular pads 6 and 7 are fitted onto the screw 5. The central positioning rod 3 is passed through the through holes of the circular pads 6 and 7, and the screw hole at the bottom of the central positioning rod 3 is tightened to the screw 5 until the pressure plate 8 around the central positioning rod 3 presses against the circular pad 7. Finally, the lower part of the mold cylinder 2 is inserted into the circular groove of the template 1. At this point, the inner wall of the mold cylinder 2 is in contact with the outer surfaces of the circular pads 6 and 7, and the outer wall of the mold cylinder 2 is in contact with the inner wall of the circular groove 4. In use, fiberglass mesh, resin, sand filler, and the fiberglass mesh on the other side are placed sequentially, and heating, pressing, and cooling processes are performed simultaneously to produce a fiberglass grinding wheel. This utility model has a reasonable structure. First, a screw 5 is set at the center of the circular groove 4 of the template 1. A circular pad 6 and a circular washer 7 are set inside the circular groove 4. The central positioning rod 3 is fastened to the screw 5 through a screw hole. A pressure plate 8 is set around the central positioning rod 3 and is pressed onto the circular pad 6 and the circular washer 7 by the pressure plate 8. Compared with the one-piece glass fiber grinding wheel forming mold, this structure makes it easier to replace the circular pad 6 and the circular washer 7. Moreover, the central positioning rod 3 with different thicknesses of circular pad 6, circular washer 7 and pressure plate 8 can be selected according to different thicknesses, which greatly improves the flexibility and applicability, thereby reducing the cost of producing glass fiber grinding wheels of different thicknesses.
