Description

Technical Field

[0001] The utility model relates to the technical field of rubber moulds, in particular to a sealing ring mould with deburred edges. Background Art

[0002] The sealing ring rubber mold is a common mold structure used for molding production of ordinary vulcanizers. The operator needs to use a feeder to manually feed the material, then heat and vulcanize it, and finally open the mold to take out the product. However, the products produced by the existing sealing ring molds have two circles of thin rubber sheets on the inner and outer rings when the sealing ring is taken out. The burrs are generated in the gap between the upper mold and the lower mold. The burrs will affect the diameter width of the rubber ring when it is used, so the rubber ring needs to be cleaned when it is used; the conventional cleaning method is to clean it by manual removal, which is relatively inefficient and has high labor costs. Liquid nitrogen has been used to cool the burrs and facilitate quick manual cleaning, but liquid nitrogen cleaning may damage the rubber ring body and may also cause harm to labor, affecting the qualified rate of the rubber ring, so it needs to be improved.

In the mold closing state, the tool 3 is attached to the inner wall of the lower mold 2 and cooperates with the upper mold 1 and the lower mold 2 to form a cavity. In the utility model, the tool 3 is a part of the upper mold 1, and the tool 3 and the upper mold 1 simultaneously form the upper mold groove 11. When the upper mold 1 and the lower mold 2 are closed, the blade of the tool 3 is in the gap between the upper mold groove 11 and the lower mold groove 21, and the tool 3 can be moved by a driving mechanism or a hydraulic mechanism to cut the excess burrs of the sealing ring.

[0027] In a specific embodiment, refer to Figure 2-Figure 6, the contour of the upper die groove 11 is larger than the lower die groove 21, the difference between the upper die groove 11 and the lower die groove 21 is equal to the thickness of the tool 3, and the inner ring contour of the tool 3 is the same as the contour of the lower die groove 21. The tool 3 is a part of the upper mold 1 and constitutes the upper die groove 11, so the contour of the tool 3 needs to be consistent with the upper die groove 11 to match the lower die groove 21. After the tool 3 is installed in the upper mold 1, it is molded with the lower mold 2 to form a complete mold cavity. At the same time, a groove for the longitudinal sliding of the tool 3 is provided on the upper mold 1. The tool 3 is installed in the groove. The upper mold 1 is composed of two molds. The two molds are engaged to clamp the tool 3 in the groove, which is convenient for the installation of the tool 3.

[0028] In a specific embodiment, refer to Figure 2-Figure 6 The lower mold 2 is provided with a column 22 located on the lower mold groove 21, and the upper mold groove 11 is provided with a groove body 12 matching the column 22. The length of the column 22 is greater than the thickness of the mold cavity, the column 22 is greater than the thickness of the mold cavity, and the redundant length of the column 22 is the same as that of the groove body 12.

[0029] In a specific embodiment, refer to Figure 1 A hydraulic groove 13 is provided on the upper mold 1, a movable groove is provided on the lower mold 2, the groove body 12 is connected with the hydraulic groove 13, a pipe groove 221 is provided in the column 22, and the pipe groove 221 is connected with the movable groove, and the pipe groove 221 is connected with the groove body 12 and the pipe groove 221.

[0030] In a specific embodiment, refer to Figure 2 , Figure 5 A hydraulic mechanism is installed in the hydraulic groove 13, and a trigger mechanism is installed in the movable groove. The hydraulic mechanism can drive the tool 3 to slide toward or away from the lower mold 2. The trigger mechanism squeezes the hydraulic mechanism through the pipe groove 221, and squeezes the burrs of the edge of the cutting tool 3 to cut the sealing ring by means of oil.

[0031] In a specific embodiment, refer to Figure 5 The hydraulic mechanism includes a push column 41, a piston 42 and a plug body 43. The piston 42 is located in the hydraulic groove 13 and blocks the groove body 12. The hydraulic groove 13 is filled with hydraulic oil and sealed by the plug body 43. The upper mold 1 is provided with a pipe groove 221 connected to the hydraulic groove 13. The push column 41 is installed in the pipe groove 221 and connected to the tool 3. The piston 42 of the hydraulic mechanism squeezes the oil in the hydraulic groove 13, and the oil will squeeze into the pipe groove 221 and push the push column 41 outward, at which time it will drive the tool 3 to push the lower mold 2, and the hydraulic groove 13 is filled with oil. The hydraulic groove 13 has a liquid injection port, and its liquid injection port is sealed by the plug body 43.

[0032] In a specific embodiment, refer to Figure 4-Figure 6The trigger mechanism includes a striker 51 and an elastic member 52.

The contact body 53 is squeezed by an external driving mechanism to drive all the strikers 51 to move upward. At this time, the piston 42 will squeeze the oil and then drive the tool 3 to move toward the lower mold 2. At this time, the elastic member 52 is in a compressed state. When the contact body 53 moves downward by gravity, the elastic member 52 will push the contact body 53 to move downward. Since the hydraulic groove 13 is in a sealed state, when the striker 51 moves downward, it will absorb the piston 42 to move downward. The hydraulic groove 13 will absorb the oil and drive the tool 3 to move upward.

[0033] In a specific embodiment, refer to Figure 3 The tool 3 is installed on the upper die groove 11 and fits the inner wall of the upper die 1. The tool 3 can form a complete die cavity with the upper die groove 11 and the lower die groove 21.

When the upper mold 1 and the lower mold 2 are molded together, the bevel 211 of the lower mold 2 can exert an upward thrust on the tool 3, so that the tool 3 has a certain thrust when it is stored in the groove of the upper mold 1, so that it is easy to restore to its original state. At the same time, the tool 3 can also be assisted in restoring to its original state by setting a spring.
