Description

Technical Field

[0001] The utility model belongs to the technical field of molding molds, and particularly relates to a rapid molding mold for hydrogel production. Background Art

[0002] Hydrogel is a gel with water as the dispersion medium. A part of hydrophobic groups and hydrophilic residues are introduced into the water-soluble polymer with a network cross-linked structure. The hydrophilic residues combine with water molecules to connect the water molecules inside the network, while the cross-linked polymer of the hydrophobic residues swells when it comes into contact with water. It is a polymer network system with soft properties, can maintain a certain shape, and can absorb a large amount of water. All water-soluble or hydrophilic polymers can form hydrogels through certain chemical cross-linking or physical cross-linking. These polymers can be divided into two categories according to their sources: natural and synthetic. Natural hydrophilic polymers include polysaccharides and polypeptides.

[0003] Most of the existing hydrogel molds are closed shells. Both the baking and heating of the cold gel and the cooling and demolding are slow, which slows down the overall molding process of the hydrogel in the mold, increases the time cost, and reduces the production efficiency. Therefore, we propose a rapid prototyping mold for hydrogel production. Utility Model Content

[0004] The purpose of the utility model is to provide a rapid prototyping mold for hydrogel production. By setting an exhaust groove, specifically during the hydrogel molding heating and cooling process, gas can enter the mold through the exhaust groove. Because the rubber plate and the mold shell are arranged at a distance, the hot air or cold air entering through the exhaust groove can heat or cool the colloid in the rubber plate more evenly, thereby increasing the molding speed of the hydrogel and reducing the required time cost, thereby improving production efficiency. This solves the problem that most existing hydrogel molds are closed shells, and the speeds of both baking and heating and cooling and demolding of the cold gel are slow, which slows down the molding process of the hydrogel as a whole in the mold, increases the time cost, and reduces production efficiency.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a rapid prototyping mold for hydrogel production, comprising a mold shell, a top cover fixedly connected to the top of the mold shell, a glue plate arranged inside the mold shell, a drainage box fixedly connected to the bottom of the mold shell, a pressing automatic rebound structure arranged at the bottom of the glue plate, a plurality of drainage pipes arranged inside the mold shell, a baffle fixedly connected to the inner wall of the mold shell, a drainage hole arranged at the bottom of the baffle, four groups of baffles are arranged, each group has the same structure, and an exhaust groove is arranged, specifically during the heating and cooling process of hydrogel molding, gas can enter the mold through the exhaust groove, because the glue plate and the mold shell are arranged at intervals, the hot air or cold air entering through the exhaust groove can heat or cool the colloid in the glue plate more evenly, thereby increasing the molding speed of the hydrogel and reducing the required time cost, thereby improving the production efficiency.

[0007] Furthermore, the top cover is provided with a plurality of exhaust holes. By providing the top cover, the upper surface of the hydrogel to be molded is protected, thereby enhancing the quality of the hydrogel after molding.

[0008] Furthermore, four groups of glue plate baffles are arranged on the top of the glue plate. By setting drainage holes, excess water generated by the hydrogel during the molding process will be discharged from the glue plate through the drainage holes, thereby removing residual liquid, ensuring that the thickness of the hydrogel film is uniform, ensuring that the film is not deformed, improving the integrity of the hydrogel during demolding, and ensuring the quality of the hydrogel.

[0009] Furthermore, two drainage holes are provided on the front of the drainage box, and a slope is provided inside the drainage box. By setting the slope, it is ensured that all water discharged from the mold shell can leave the interior of the drainage box through the slope, ensuring that the mold does not need to be drained regularly, thereby improving productivity and reducing time and labor costs.

[0010] Furthermore, the press-to-rebound structure includes a pushing rod, a sliding block is fixedly connected to the bottom of the pushing rod, the sliding block is provided with a special-shaped groove, the inner wall of the special-shaped groove is slidably connected with a sliding twist, the front of the sliding twist is fixedly connected to a connecting rod, the bottom of the connecting rod is fixedly connected to a rotating shaft, the bottom of the sliding block is fixedly connected to a spring, and the bottom of the spring is fixedly connected to a rebound structure shell. Each group of the press-to-rebound structures has the same structure. By setting the press-to-rebound structure, the hydrogel can be easier to demold after molding, reducing time and labor costs.

[0011] Furthermore, the bottom of the glue plate contacts the top of the push rod, the glue plate baffles are provided in four groups and each group has the same structure, the four groups of glue plate baffles are slidably connected with the four groups of baffles, and the top of the glue plate baffle contacts the bottom of the top cover. By setting the glue plate baffles and the push rod, the glue plate and the mold shell can be pressed to be removed, which provides a basis for simple demolding, reduces labor costs, and makes demolding easier.

[0012] Furthermore, the bottom surface of the press-automatic rebound structure is fixedly connected to the bottom of the inner wall of the mold shell, a hole is provided at the top of the rebound structure shell, the push rod is slidably connected to the hole, a groove is provided on the front of the bottom of the rebound structure shell, the rotating shaft is rotatably connected to the groove, and the top surface of the push rod is in contact with the bottom surface of the glue plate. By setting the push rod, the linkage between the press-automatic rebound structure and the glue plate is realized, making it easier to remove the glue plate, laying the foundation for the simple demolding of the hydrogel.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model provides an exhaust groove. Specifically, during the heating and cooling process of hydrogel molding, gas can enter the mold through the exhaust groove. Since the rubber plate and the mold shell are spaced apart, the hot air or cold air entering through the exhaust groove can heat or cool the colloid in the rubber plate more evenly, thereby increasing the molding speed of the hydrogel and reducing the time cost required, thereby improving production efficiency.

[0015] 2. The utility model provides drainage holes. Specifically, excess water generated during the hydrogel molding process will be discharged from the gel plate through the drainage holes, thereby removing residual liquid, ensuring that the thickness of the hydrogel film is uniform, ensuring that the film is not deformed, improving the integrity of the hydrogel during demolding, and ensuring the quality of the hydrogel.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The top cover 3 is provided with a plurality of exhaust holes 31, and four groups of glue plate baffles 21 are arranged on the top of the glue plate 2.

[0029] A second drainage hole 41 is provided on the front of the drainage box 4 , and a slope is provided inside the drainage box 4 .

[0030] The push-down automatic rebound structure includes a push rod 52, a sliding block 53 is fixedly connected to the bottom of the push rod 52, the sliding block 53 is provided with a special-shaped groove 56, the inner wall of the special-shaped groove 56 is slidably connected with a sliding twist 54, the front of the sliding twist 54 is fixedly connected to a connecting rod 55, the bottom of the connecting rod 55 is fixedly connected to a rotating shaft 58, the bottom of the sliding block 53 is fixedly connected to a spring 57, and the bottom of the spring 57 is fixedly connected to a rebound structure shell 51, and each group of push-down automatic rebound structures has the same structure.

[0031] The bottom of the rubber plate 2 contacts the top of the push rod 52 , four groups of rubber plate baffles 21 are provided and each group has the same structure, the four groups of rubber plate baffles 21 are slidably connected to the four groups of baffles 11 , and the top of the rubber plate baffles 21 contacts the bottom of the top cover 3 .

[0032] The bottom surface of the automatic rebound structure is fixedly connected to the bottom of the inner wall of the mold shell 1. A hole is opened at the top of the rebound structure shell 51, and the push rod 52 is slidably connected to the hole.

The top surface of the push rod 52 contacts the bottom surface of the rubber plate 2.

[0033] A specific application of this embodiment is as follows: when in use, the user removes the top cover 3 from the mold shell 1 and pours the hydrogel into the glue plate 2. Since there is no gap between the glue plate baffle 21 and the baffle 11, the hydrogel will fall evenly on 2. When the pouring is completed, the user covers the top cover 3 on the top of the mold shell 1 to snap and fix it, and then puts the filled mold into the oven for heating, so that the gel raw material undergoes a chemical reaction or physical action at high temperature. During the heating process, excess water in the gel will flow into the mold shell 1 through the drainage hole 12, and then flow into the drainage box 4 through the drainage pipe 13. The water is discharged from the drainage hole 2 41 through the slope, and the hot air will enter the mold shell 1 and the glue plate 2 through the exhaust hole 31, so that the hydrogel is evenly heated. After the heating is completed, the heated mold is taken out.

Because there is a gap between the glue plate baffle 21 and the inner wall of the mold shell 1, and the glue plate baffle 21 is thin, the cooling speed will be faster. After the cooling is completed, the top cover 3 is pressed, and the force is applied to the push rod 52 through the glue plate baffle 21 and the glue plate 2. The push rod 52 moves downward, so that the connecting rod 55 slides downward in the special-shaped groove 56 to cancel the engagement. At the same time, the spring 57 returns upward, pushing the sliding block 53 upward, and the sliding block 53 drives the push rod 52 to move. The push rod 52 pushes the glue plate 2 to move upward. At the same time, the glue plate 2 drives the glue plate baffle 21 to slide upward on the outer surface of the baffle 11. The user can take out the glue plate 2 and the glue plate baffle 21 to take out the formed hydrogel.
