Description

Technical Field

[0001] The utility model relates to the technical field of silicone molds, in particular to an anti-deformation silicone mold. Background Art

[0002] Silica gel is a highly active adsorption material and an amorphous substance. The main component of silica gel is silicon dioxide. It has stable chemical properties and is non-flammable. It is a transparent or milky white granular solid with an open porous structure and strong adsorption. It can adsorb a variety of substances. Specific molds are required for silica gel processing.

[0003] Prior art, such as the patent with publication number CN218453114U, discloses an anti-deformation silicone mold, which belongs to the technical field of silicone molds. The key points of its technical solution include a base, a guide rod is arranged at the upper end of the base, a mounting seat is arranged at the outer side of the guide rod, a limit block is arranged at the upper end of the guide rod, a spring is arranged at the upper end of the base, a cavity is opened inside the mounting seat, a mounting seat is arranged at the outer side of the template, a spring is arranged between the mounting seat and the bottom, which plays a buffering role for the template, and the template adopts a quadrangular pyramid structure. Compared with the traditional square structure, the bottom area is larger and the structure is more stable, which reduces the damage to the mold caused by pressure and prevents deformation of the mold caused by external pressure. A temperature sensor is arranged on the outer side of the template. When the temperature of the template is high, the coolant enters the mounting seat through the water inlet pipe and contacts the template through flow channel one and flow channel two, so that the template can be cooled quickly, preventing deformation of the mold caused by high temperature and improving the service life of the mold.

[0005] In the above-mentioned prior art, the mold is cooled to prevent deformation by conveying cooling liquid to the runner one and the runner two. However, the cooling liquid is located in the runner one and the runner two. The cooling liquid reduces the temperature of the silicone raw material when it is heated and melted, affecting the heating and molding of the silicone parts. At the same time, there is a lack of uniform cooling of the silicone parts. If the cooling effect of the silicone parts is uneven, it is easy to cause deformation when taking them out of the mold. For this reason, an anti-deformation silicone mold is proposed. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-5 The anti-deformation silicone mold of this embodiment includes a bottom mold 1 and a molding groove 13 opened on the upper surface of the bottom mold 1. A first water tank 2 is opened inside the bottom mold 1. An inlet pipe 3 and a drain pipe 4 are installed on the outer wall of the bottom mold 1. One end of the inlet pipe 3 and the drain pipe 4 are both connected to the inside of the first water tank 2. A first sealing push plate 5 is slidably connected in the first water tank 2.

The first pushing rod 63 is slidably connected to the bottom mold 1.

[0026] like Figure 1-5 As shown, the silicone mold structure in the utility model is similar to the existing silicone mold structure, such as the prior art CN218453114U. The main improvement of the utility model is to ensure the cooling of the silicone mold and the silicone parts, while ensuring the heating and molding of the silicone parts; in the process of molding the silicone parts, if the silicone parts and the bottom mold 1 need to be cooled, cold water can be transported to the first water tank 2 through the water inlet pipe 3, and the cold water enters the first water tank 2 to cool the bottom mold 1 and the silicone parts formed in the molding tank 13, and the cold water takes away the heat and flows out of the drain pipe 4 When the silicone raw material placed in the molding groove 13 needs to be heated, stop supplying cold water to the water inlet pipe 3, and start the first cylinder 61 at this time. The first cylinder 61 drives the first connecting plate 62 to move, and the first connecting plate 62 drives the first push rod 63. The first push rod 63 drives the first sealing push plate 5 to move in the first water tank 2. The first sealing push plate 5 drives the residual water in the first water tank 2 to be squeezed out from the drain pipe 4, thereby avoiding the residual cold water in the first water tank 2 affecting the heating temperature of the silicone parts, thereby affecting the molding of the silicone parts, and ensuring that the bottom mold 1 and the silicone parts will not be deformed.

The cold water is sent into the first water trough 2 and the second water trough 7 to cool the bottom mold 1 and the silicone parts. When the cold water in the first water trough 2 and the second water trough 7 needs to be discharged, the first cylinder 61 is started first to make the first sealing push plate 5 discharge most of the water in the first water trough 2 and the second water trough 7 from the drain pipe 4, and then the first sealing push plate 5 moves back to fit the inner wall of the first water trough 2, and then the second cylinder 91 is started to make the second sealing push plate 8 push the remaining water in the first water trough 2 and the second water trough 7 from the drain pipe 4, thereby increasing the cooling space for the bottom mold 1 and the silicone parts and increasing the uniformity of cooling.

[0028] like Figure 2-5 As shown, the first water trough 2 and the second water trough 7 are both U-shaped structures, and the upper ends of the first water trough 2 and the second water trough 7 are both located on the peripheral side of the molding groove 13; the cold water in the U-shaped first water trough 2 and the second water trough 7 can cool down the bottom surface and peripheral side of the silicone member located in the molding groove 13, thereby improving the uniformity of cooling the silicone member and avoiding deformation of the silicone member.

[0029] like Figure 4 , 5 As shown, the inner walls at one end of the first water tank 2 and the second water tank 7 are both provided with a makeshift groove 10, and the first sealing push plate 5 and the second sealing push plate 8 are movably connected to the two makeshift grooves 10 respectively; the makeshift groove 10 accommodates the first sealing push plate 5 and the second sealing push plate 8, and facilitates the dislocation movement of the first sealing push plate 5 and the second sealing push plate 8, so that the cold water in the first water tank 2 and the second water tank 7 can be discharged.

[0030] like Figure 2 , 3 As shown, the number of the first push rod 63 and the second push rod 93 are both multiple, and one end of the multiple first push rods 63 are respectively fixed to the middle part and both ends of the side wall of the first sealing push plate 5, and one end of the multiple second push rods 93 are respectively fixed to the middle part and both ends of the side wall of the second sealing push plate 8; multiple first push rods 63 and multiple second push rods 93 can respectively improve the strength and stability of pushing the first sealing push plate 5 and the second sealing push plate 8.

[0031] like Figure 5As shown, a disassembly groove 11 is provided on the bottom surface of the bottom mold 1, and the disassembly groove 11 is connected with the first water tank 2 and the second water tank 7. A sealing plate 12 is installed in the disassembly groove 11, and the first sealing push plate 5 and the second sealing push plate 8 both slide on the upper surface of the sealing plate 12; the sealing plate 12 is fixed to the bottom surface of the bottom mold 1 by bolts, and the first water tank 2 and the second water tank 7 can be easily cleaned through the disassembly groove 11, and the first water tank 2 and the second water tank 7 can also be opened. The sealing plate 12 blocks the disassembly groove 11 to seal it.

[0032] like Figure 2-5 As shown, the distance between the first water trough 2 and the second water trough 7 and the inner wall of the molding trough 13 is not greater than 4 cm; the distance between the first water trough 2 and the second water trough 7 and the inner wall of the molding trough 13 is relatively small, thereby improving the effect of the cold water in the first water trough 2 and the second water trough 7 on cooling the injection molded parts in the molding trough 13.

When the silicone raw material placed in the molding tank 13 needs to be heated, the cold water is stopped from being transported to the water inlet pipe 3, and the first cylinder 61 is started to work first, and the first cylinder 61 drives the first connecting plate 62 to move, and the first connecting plate 62 drives the first push rod 63, and the first push rod 63 drives the first sealing push plate 5 to move in the first water tank 2, and the first sealing push plate 5 drives part of the water in the first water tank 2 and the second water tank 7 to be squeezed out from the drain pipe 4, and then the first sealing push plate 5 is driven back to its original position by the first cylinder 61, and then the second cylinder 91 is started to work, and the second cylinder 91 works to push the second sealing push plate 8 to move through the second connecting plate 92 and the second push rod 93, so that the second sealing push plate 8 can push the remaining water in the first water tank 2 and the second water tank 7 out of the drain pipe 4, so as to avoid the cold water remaining in the first water tank 2 and the second water tank 7 affecting the heating temperature of the silicone parts and affecting the molding of the silicone parts.
