Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-4 The present invention provides a technical solution: a mold device, comprising: The skeleton 5 to be assembled with the sealing ring, the injection plug 1 arranged from top to bottom, and the positioning component for fixing the skeleton 5 are provided. The skeleton 5 is provided with a sealing groove 51, and the bottom end of the injection plug 1 is provided with a discharge port 11, which is correspondingly arranged with the sealing groove 51.

[0014] By fixing the skeleton 5 of the sealing ring to be assembled using the positioning component, and then pouring the material into the sealing groove 51 opened on the skeleton 5 by the injection plug 1 to vulcanize the sealing ring, the resulting sealing ring can completely fit the sealing groove 51 of the skeleton 5.

[0015] In this embodiment, the positioning component includes an upper module 2, a middle module 3, and a lower module 4 arranged from top to bottom. The injection plug 1 is snapped and fixed on the upper module 2, and the discharge port 11 passes through the middle module 3.

[0016] In this embodiment, the bottom end of the upper module 2 is also provided with an annular groove 21. The groove opening of the annular groove 21 and the groove opening of the sealing groove 51 are respectively provided to form a cavity for forming a sealing ring. The skeleton 5 is provided with a flow channel 52, which is connected to the sealing groove 51. The discharge port 11 is correspondingly provided with the flow channel 52.

[0017] The cavity of the sealing ring is formed by the corresponding groove of the annular groove 21 and the groove of the sealing groove 51. The material is then discharged and poured through the discharge port 11, which facilitates the direct formation of a completely fitted sealing ring on the skeleton 5 of the sealing ring to be assembled. This eliminates the need to produce the sealing ring separately and assemble it later, thus improving work efficiency.

[0018] In this embodiment, a protrusion is provided at the top of the lower module 4, and the protrusion is snapped and fixed to the frame 5.

[0019] In this embodiment, a fixing block 22 is fixedly connected to the bottom end of the upper module 2, and the fixing block 22 is snapped and fixed to the frame 5.

[0020] In this embodiment, the top end of the middle module 3 is snapped and fixed to the bottom end of the upper module 2, the bottom end of the middle module 3 is snapped and fixed to the top end of the lower module 4, a fixing groove is provided on the middle module 3, and the outer wall of the frame 5 is fitted with the inner wall of the fixing groove.

[0021] By fitting the outer wall of the frame 5 of the sealing ring assembly to the inner wall of the fixing groove of the middle module 3, and using the fixing block 22 of the upper module 2 to snap and fix the frame 5, as well as the protrusion of the lower module 4 to snap and fix the frame 5, the frame 5 is prevented from shaking during the vulcanization and casting of the sealing ring, thus avoiding affecting the formation of the sealing ring.

[0022] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
