[0002] Molds are various molds and tools used in industrial production to obtain desired products through injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, and other methods. Among these, injection molds are required for the molding of rubber sealing rings. According to the patent document with authorization announcement number CN222858671U, entitled "A Rubber Sealing Ring Mold for Easy Demolding," it includes a fixed platform and a base. The base is fixedly connected to the bottom of the fixed platform, and a fixed cover is fixedly connected to the top of the fixed platform. A fixed seat is fixedly connected inside the fixed cover, and a left mold base is fixedly connected to the left side inside the fixed cover. Fixed rods are fixedly connected to the four corners of one side of the left mold base. The left mold base has a... A right mold base is provided, with a mold base fixedly connected to its left side. A square groove is provided inside the left side of the right mold base, and a first reserved groove is provided inside the right side of the right mold base. A push frame is provided inside the square groove, and connecting rods are fixedly connected to the four corners of the right side of the push frame. One side of the connecting rod passes through the interior of the first reserved groove and is fixedly connected to a fixed frame. A movable rod is fixedly connected to the top right side of the fixed frame.

A second cylinder is fixedly connected to the right side inside the fixed cover, and a first telescopic rod is movably connected to the left side of the second cylinder. However, the following defects still exist:

[0003] This causes the pusher frame to move to one side and push out the rubber sealing ring outside the mold base. However, if the surface of the mold cavity is not smooth enough and there are minor bumps and imperfections, the rubber sealing ring may fit tightly against these uneven areas during the molding process, generating a large adhesion force, making it difficult to detach smoothly from the mold cavity during subsequent demolding.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figure 1 The present invention relates to a rubber sealing ring mold that is easy to demold, including a base 1, a demolding mechanism 2 on the base 1, and a lifting mechanism 3 on the top of the base 1.

[0023] Specifically, by Figure 2 The demolding mechanism 2 includes a U-shaped cylindrical rod 201 fixed to the bottom of the base 1. Two upright plates 2015 are symmetrically and movably sleeved on the outer side of the U-shaped cylindrical rod 201. Connecting blocks 2012 are fixedly connected to the sides of the two upright plates 2015 that are close to each other. Lower semi-circular molds 2013 are fixedly connected to the two connecting blocks 2012. The two lower semi-circular molds 2013 fit together and are the same in shape and size. Two through slots 4 are symmetrically provided on the base 1, and the two upright plates 2015 slide with the two through slots 4 respectively. The base 1 is connected to a chassis 2011, with two lower semi-circular molds 2013 located on top of the chassis 2011. A U-shaped rod 204 is fixedly connected to the bottom of the base 1. A sliding plate 208 is movably sleeved on the outer side of the U-shaped rod 204. Two connecting posts 2016 are symmetrically fixedly connected between the sliding plate 208 and the chassis 2011. Both connecting posts 2016 penetrate the base 1 and are movably connected to it. Two outer rings 2010 are symmetrically fixedly sleeved on the outer side of the U-shaped rod 204. Springs 209 are fixedly connected between the bottom of the base and the slide plate 208. Both springs 209 are sleeved on the outside of the second U-shaped rod 204. The springs 209 help stabilize the chassis 2011 on top of the base 1. A threaded sleeve 207 located below the slide plate 208 is movably sleeved on the outside of the second U-shaped rod 204. Two movable rods 202 are symmetrically rotatably connected to the outside of the threaded sleeve 207. The tops of the two movable rods 202 are rotatably connected to the bottom of the two upright plates 2015. The middle of the outer side of the first U-shaped rod 201 is fixed... An upper sleeve block 2014 is fixedly fitted, and a lower sleeve block 206 is fixedly fitted to the middle of the outer side of the U-shaped round rod 204. A drive motor 203 is fixedly installed at the bottom of the upper sleeve block 2014, and a screw 205 is fixedly connected to the drive motor 203. The bottom end of the screw 205 is rotatably connected to the top of the lower sleeve block 206. A sliding plate 208 is located outside the screw 205. The sliding plate 208 does not contact the screw 205 to avoid the sliding plate 208 causing wear on the threads on the outside of the screw 205. The screw sleeve 207 is threadedly fitted onto the outside of the screw 205.

[0024] In operation, the drive motor 203 is first started, which drives the screw 205 to rotate and causes the screw sleeve 207 to slide upward along the second U-shaped rod 204. The two movable rods 202 drive the two upright plates 2015 to slide along the first U-shaped rod 201. The two connecting blocks 2012 then drive the two lower semi-circular molds 2013 to move. When the two lower semi-circular molds 2013 are completely removed from the top of the chassis 2011, the screw sleeve 207 abuts against the slide plate 208. Then, the screw sleeve 207 continues to rise and pushes the slide plate 208 to slide upward along the second U-shaped rod 204. The two connecting columns 2016 drive the chassis 2011 to move upward and push the rubber sealing ring on its top, finally achieving the smooth demolding of the rubber sealing ring.

[0025] Specifically, by Figure 3 The lifting mechanism 3 includes an L-shaped rod 301 fixed to the top of the base 1. A column 307 is fixedly connected between the L-shaped rod 301 and the base 1. A lifting plate 309 is movably sleeved on the outer side of the column 307. A cylinder 3011 is fixedly installed between the top of the lifting plate 309 and the L-shaped rod 301. A lifting ring 308 is fixedly connected to the outer side of the lifting plate 309. An upper mold 306 is provided at the bottom of the lifting ring 308. The outer diameter of the upper mold 306 is equal to the inner diameter of the lifting ring 308. The top of the ring 308 is provided with an injection port 305. The top of the lifting ring 308 is fixedly connected with a U-shaped round rod 3010. A bracket 304 is movably sleeved on the outside of the U-shaped round rod 3010. The bracket 304 is fixed to the top of the upper mold 306. A sleeve frame 302 is fixedly sleeved on the middle of the outside of the U-shaped round rod 3010. A cylinder 303 is fixedly installed between the sleeve frame 302 and the bracket 304. The sleeve frame 302 is movably sleeved on the outside of the column 307, and the cylinder 3011 passes through the sleeve frame 302.

[0026] In use, first activate cylinder 2 3011, which drives the lifting plate 309 to slide upward along the column 307 and moves the lifting ring 308 upward, so that the upper mold 306 is removed between the two lower semi-circular molds 2013. When the rubber sealing ring is located outside the upper mold 306, activate cylinder 1 303, which drives the bracket 304 to slide upward along the U-shaped rod 3010 and raises the upper mold 306 to the top of the lifting ring 308. Finally, push out the rubber sealing ring for removal.
