In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] This embodiment provides a tooling fixture for processing a sealing sleeve, see Figures 1 to 3 As shown, it includes: an upper mold 1, a lower mold 2 and a forming mold 3;

[0023] The upper die 1, the forming die 3 and the lower die 2 are arranged from top to bottom in sequence; the upper die 1 and the forming die 3 are snap-fitted together, and the lower die 2 is buckled onto the forming die 3; positioning pins 11 are provided around the upper die 1 and cooperate with the positioning holes 7 of the lower die 2.

[0024] A rubber sheet 4 required for processing is placed between the forming mold 3 and the upper mold 1 and the lower mold 2; the forming mold 3 is provided with a threaded portion 5 and a smooth portion 6 from the middle to both sides, and the smooth portion 6 is located on one side of the threaded portion 5. The threaded portion 5 allows the inner wall of the processed rubber sheet 4 to be engraved with thread patterns accordingly, which is convenient for installation and use, and the smooth surface is convenient for manual extraction of the processed sealing sleeve.

[0025] Handles 13 are also installed on both ends of the upper mold 1. The handles 13 are welded to the upper mold 1. The upper mold 1 is welded with the handles 13 to facilitate the hand to hold when the rubber sheet 4 is hot-melted in the temperature-controlled furnace.

[0026] Positioning holes 7 are provided around the lower mold 2, a positioning column 8 is provided in the middle of the lower mold 2, and a plurality of stepped grooves 9 that cooperate with the forming mold 3 are provided on the end face of the lower mold 2. The positioning holes 7 and the positioning pins 11 are convenient for positioning when the upper mold 1 and the lower mold 2 are installed. The groove 9 is semicircular, and the plurality of steps cooperate with the forming mold 3, so that the forming mold 3 can be stuck in the groove 9 after installation.

[0027] When the lower mold 2 and the lower mold 2 are buckled together, the end surfaces fit together, and after fitting, it is ensured that the rubber plate 4 can completely contact with the upper mold 1, the lower mold 2 and the forming mold 3.

[0028] Guide rods 12 are installed on both ends of the forming mold 3. The end surface of the forming mold 3 facing the lower mold 2 is provided with a through hole 10 that cooperates with the positioning column 8 on the lower mold 2. The through hole 10 and the two positioning columns 8 cooperate with each other for positioning and installation of the forming mold 3 on the lower mold 2; the guide rods 12 at both ends of the forming mold 3 are for easy grasping by hand after heating in the temperature-controlled furnace.

[0029] The forming mold 3 and the rubber plate 4 are hot-melted to form a cylindrical sealing sleeve, and the cylindrical shape and the forming mold 3 are in close contact with each other.

[0030] Working principle: First, the lower mold 2 is placed on the workbench, and two appropriate rubber plates 4 are placed on the groove 9 of the lower mold 2; then, the molding mold 3 is positioned and installed on the lower mold 2 through the positioning column 8 and the through hole 10 to ensure that the two ends of the lower mold 2 and the molding mold 3 fit each other, and two rubber plates 4 are also placed on the top of the molding mold 3; secondly, the upper mold 1 is buckled on the lower mold 2 and the molding mold 3, and positioned and installed by the positioning pin 11 and the positioning hole 7; finally, the upper mold 1, the lower mold 2, the molding mold 3 and the rubber plate 4 are placed in a temperature-controlled furnace for hot melting, and after being taken out for a period of time, each sealing sleeve passing through the smooth surface 6 is extracted by an air gun, thereby ensuring that each sealing sleeve can maintain the same precision requirements, and the upper mold 1 and the lower mold 2 are pressed against each other to prevent adjacent sealing sleeves from sticking to each other.

[0031] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
