Description

Technical Field

[0001] The utility model relates to the technical field of compression molds, in particular to a compression mold for a rubber sealing ring. Background Art

[0002] Molding is the abbreviation of compression molding, also known as compression molding. Generally, powder, granules, pellets, sheets or rough blanks are placed in a heated mold cavity, and then the mold is closed and pressurized to form and solidify it, and then the product is demolded. It is often used to manufacture plastics, plastics, silicone and rubber products.

[0003] A compression mold is required for the production of rubber sealing rings. The existing compression mold is usually composed of an upper and lower mold. After the rubber ring is formed, the mold needs to be opened and taken out. However, when the mold is opened, the rubber ring is often difficult to be removed smoothly due to its close fit with the inner wall of the mold and the viscosity of the rubber itself. This problem not only affects the production efficiency, but may also damage the quality of the rubber ring. Improper operation during the removal process may cause the rubber ring to deform, break or produce other defects, thereby affecting its sealing and connection performance. For this reason, we propose a compression mold for a rubber sealing ring. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] See also Figure 1-6 The utility model provides a technical solution: a rubber sealing ring molding die, including an upper die 1 and a lower die 2, the upper die 1 and the lower die 2 are arranged in parallel, and also include a cavity 3 opened in the upper die 1 and a core 4 arranged in the lower die 2, and a pneumatic ejecting component 5 is arranged in the lower die 2 to eject the molded sealing ring.

[0025] A guide rod 7 is fixedly provided on the lower mold 2, and a socket 8 is provided on the upper mold 1. The guide rod 7 is plugged into the socket 8 so that the upper mold 1 can move up and down along the guide rod 7, which is convenient for stable mold opening and closing.

[0026] A connecting cavity 9 is provided in the lower mold 2, and a through groove 10 is provided on the surface of the lower mold 2. The through groove 10 is connected to the connecting cavity 9 and the two are coaxially arranged. The core 4 includes a fixed seat 41 and a push rod 42 fixed on the fixed seat 41. The fixed seat 41 is slidably arranged in the through groove 10. The outer diameter of the fixed seat 41 is the same as the inner diameter of the through groove 10, so that the fixed seat 41 can close the through groove 10, so that a molding cavity 3 is formed between the upper mold 1 and the lower mold 2 when producing the sealing ring.

[0027] The pneumatic ejection assembly 5 includes an air storage box 51 fixedly arranged at the bottom of the lower mold 2. The air storage box 51 is externally connected to a fan. There is a certain air pressure in the air storage box 51. A connecting hole 52 connected to the air storage box 51 is opened in the lower mold 2. A sealing member 6 is arranged in the through groove 10. The sealing member 6 is connected to the fixed seat 41. When the fixed seat 41 moves, it can drive the sealing member 6 to open the through groove 10, thereby allowing the gas in the air storage box 51 to enter the connecting cavity 9 from the connecting hole 52.

[0028] The blocking member 6 includes a fixing ring 61 fixedly arranged in the through groove 10, a connecting spring 62 is arranged at the bottom of the fixing ring 61, a connecting seat 63 is fixedly connected to the end of the connecting spring 62, a blocking rod 64 is fixedly arranged on the upper surface of the connecting seat 63, the outer diameter of the blocking rod 64 coincides with the inner diameter of the fixing ring 61, a connecting rod 65 is fixedly arranged at the top of the blocking rod 64, the top of the connecting rod 65 is fixedly connected to the fixing seat 41, a transmission rod 66 is slidably penetrated in the air storage box 51, and the top of the transmission rod 66 is fixedly connected to the connecting seat 63 A connecting frame 67 is provided at the bottom end, and the connecting frame 67 is connected to an external cylinder. When the cylinder drives the connecting frame 67 and the transmission rod 66 to move downward, the transmission rod 66 drives the connecting seat 63, the blocking rod 64 and the connecting rod 65 to move, thereby causing the blocking rod 64 to separate from the fixing ring 61. At this time, the gas in the gas storage box 51 enters the connecting cavity 9 from the connecting hole 52. At the same time, the connecting rod 65 drives the fixing seat 41 to move downward, so that the gas in the connecting cavity 9 is ejected from the through groove 10, and then the gas impacts the formed sealing ring to separate it from the lower mold 2.

[0029] In summary, during demolding, the upper mold 1 is separated from the lower mold 2, and the cylinder is started at this time. The cylinder drives the connecting frame 67 and the transmission rod 66 to move downward, and the transmission rod 66 drives the connecting seat 63, the blocking rod 64 and the connecting rod 65 to move, thereby separating the blocking rod 64 from the fixing ring 61. At this time, the gas in the air storage box 51 enters the connecting cavity 9 from the connecting hole 52. At the same time, the connecting rod 65 drives the fixing seat 41 to move downward, so that the gas in the connecting cavity 9 is ejected from the through groove 10, and then the gas impacts the formed sealing ring to separate it from the lower mold 2, and then the cylinder drives the above structure to reset to complete a molding and material taking operation.

[0030] Embodiment 2:

[0031] The main structure of the second embodiment is the same as that of the first embodiment, except that a heat insulating pad is arranged between the air storage box 51 and the lower mold 2, and the fan externally connected to the air storage box 51 is a cooling fan. Since the rubber sealing ring needs to be heated during molding, a heat insulating pad is arranged between the air storage box 51 and the lower mold 2 to prevent heat from being transferred to the air storage box 51. The gas temperature in the air storage box 51 is relatively low, which can not only assist the sealing ring to separate from the lower mold 2 during ejection, but also cool the sealing ring, accelerate its molding, and prevent it from deforming during material removal.
