DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects realized by the utility model more clear and easy to understand, the utility model will be further described below in combination with the drawings and specific embodiments:

[0026] As shown in Figures 2 to 6 The utility model discloses a vulcanization type sealing ring mold, which comprises a base 2, an upper mold 4 and a lower mold 3. The base 2 is provided with a plurality of insertion holes. Each insertion hole is used for inserting the lower mold 3. The top surface of the lower mold 3 is recessed to form a forming hole 31. The forming hole 31 is divided into an upper hole section and a lower hole section. The lower hole section has a conical structure. The small end of the lower hole section is located below the large end of the lower hole section. The large end of the lower hole section is connected to the upper hole section. The inner wall of the upper hole section is recessed to form a plurality of toothed annular grooves 32. The toothed annular grooves 32 are used for forming the upper tooth pattern of the vulcanization type sealing ring 1. The upper mold 4 is used for buckling the forming hole 31. The upper mold 4 comprises a blocking section 41 and an extending section 42. The blocking section 41 is used for pressing on the top surface of the lower mold 3 and blocking the forming hole 31. The extending section 42 extends below the blocking section 41 and extends into the forming hole 31. The inner wall of the forming hole 31 and the outer wall of the extending section 42 form a forming cavity. The forming cavity is used for forming the vulcanization type sealing ring 1. The blocking section 41 is provided with a pouring channel. The pouring channel is connected to the forming cavity.

[0027] The pouring channel comprises a center pouring channel 411, an intermediate communication channel 412, and at least three columnar pouring channels 413, the adjacent columnar pouring channels 413 are spaced, the columnar pouring channels 413 are located in the vertical direction, the bottom end of the columnar pouring channel 413 is communicated with the forming cavity, the top end of the columnar pouring channel 413 is communicated to one end of the intermediate communication channel 412, the other end of the intermediate communication channel 412 is connected to the center pouring channel 411, and the center pouring channel 411 is used for injecting the material. Since the edge of the vulcanized sealing ring 1 needs to be manually extruded to make the tooth pattern and the tooth-shaped annular groove 32 separate, if there is only one columnar pouring channel 413, although the vulcanized sealing ring 1 can be formed after the material is injected, there is only one pouring column 13, and only one pouring column 13 can be used to pull the edge of the vulcanized sealing ring 1 to make the tooth pattern and the tooth-shaped annular groove 32 separate, which is difficult to separate. Therefore, in the present application, there are more than three columnar pouring channels 413, at least three pouring columns 13 are formed on the top surface of the vulcanized sealing ring 1, and at least three points can be used to pull the edge of the vulcanized sealing ring 1 to make the tooth pattern and the tooth-shaped annular groove 32 separate, and it is easier to separate when three points are pulled at the same time, which improves the demolding efficiency.

[0028] The inner bottom wall of the forming hole 31 is recessed to form a through hole 33 penetrating the lower mold 3, and the protruding insertion column 43 is inserted into the through hole 33 when the blocking section 41 is buckled to the forming hole 31. The through hole 33 is arranged to realize the positioning of the lower mold 3 and the lower mold 3 through the cooperation of the inner wall of the through hole 33 and the insertion column 43.

[0029] The bottom end of the insertion column 43 is formed with a guide section, the guide section is a conical table structure, and the small end of the guide section is located above the large end of the guide section. The shape and structure design of the guide section makes the insertion column 43 more easily inserted into the through hole 33, and finally realizes the effect of close positioning of the insertion column 43 and the inner wall of the through hole 33.

[0030] The blocking section 41 of each upper mold 4 is buckled with a mold cover 5 above, the mold cover 5 is buckled to the top of the pouring channel, and the mold cover 5 is provided with a communication pipe 50, which is used for connecting the center pouring channel 411. The center pouring channel 411 and the intermediate pouring channel can be opened, which is convenient for removing the solidified material and avoids blocking the center pouring channel 411 and the intermediate pouring channel.

[0031] All the mold covers 5 are fixed to a first lifting seat 61, the first lifting seat 61 is fixed to the output end of a first lifting driving mechanism 62, the first lifting driving mechanism 62 is installed on a mounting frame 7, and the mounting frame 7 is installed beside the base 2. All the upper molds 4 are automatically driven to rise and fall together.

[0032] The vulcanized sealing ring 1 mold further comprises an ejection device for ejecting the lower mold 3 placed in the hole from the base 2.

[0033] The ejection device comprises an ejection cylinder 91, a second lifting seat 92 and a second lifting driving mechanism 93. The base 2 is installed on the support frame 8. The support frame 8 is provided with a positioning seat below the base 2. The second lifting driving mechanism 93 is installed on the positioning seat. The output end of the second lifting driving mechanism 93 is connected to the second lifting seat 92. The second lifting seat 92 is connected with a plurality of ejection cylinders 91. The ejection cylinders 91 can extend into the placement hole. The positioning seat guides the lifting of the ejection cylinder 91. All the lower molds 3 are ejected out of the placement hole, which facilitates the disassembly of the lower mold 3.

[0034] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the present application. They should be covered in the scope of the claims of the present application.
