Description

Technical Field

[0001] This utility model relates to the field of silicone material molding technology, specifically to a molding equipment for high-performance medical silicone materials. Background Technology

[0002] High-performance medical silicone is widely used in the manufacture of medical products such as medical catheters, prosthetic implants, seals, and dressing carriers due to its good biocompatibility, aging resistance, excellent elasticity, and non-toxicity and odorlessness. Its molding quality directly determines the safety, functionality, and service life of medical products, and is a key link in ensuring the reliable operation of medical equipment and the effectiveness of clinical treatment.

[0003] In the molding process of high-performance medical silicone, parameters such as temperature, pressure, and molding time must be strictly controlled. Excessive temperature can easily lead to aging and performance degradation of silicone materials, while uneven pressure can cause defects such as bubbles and material shortages in the product.

[0004] For example, Chinese utility model patent application number 202222142847.6 discloses a silicone mold forming device with a novel design and ingenious structure. It first loads an appropriate amount of silicone into an injection cylinder, and then completely delivers the silicone into the mold cavity, ensuring consistent injection volume each time, thus guaranteeing product quality and improving the yield rate. However, this device still has certain shortcomings. After molding, the silicone needs to be removed from the mold before the next batch of molds can be molded. The time spent on the removal operation increases, which reduces the output efficiency of the equipment per unit time.

[0005] Therefore, we propose a high-performance molding equipment for medical silicone materials to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a high-performance molding equipment for medical silicone materials, in order to solve the problem mentioned in the background art that currently on the market, after molding, the silicone in the mold needs to be removed before the next batch of molds can be molded, which increases the time occupied by the removal operation and thus reduces the output efficiency of the equipment per unit time.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-performance medical silicone material molding equipment, comprising a base, support plates installed on both the left and right sides of the upper surface of the base, a top plate installed above the support plates, a punch installed below the top plate via a telescopic rod, and a first die and a second die respectively provided on the left and right sides of the upper surface of the base. A cooling fan is installed on the right side of the lower surface of the top plate, a cold water tank is installed on the right side of the support plate, and a cooling water pipe is installed on the left side of the cold water tank.

[0008] Preferably, a cylinder is installed on the upper surface of the top plate, and the lower part of the cylinder is connected to the telescopic rod.

[0009] With the above structural design, when mold closing and molding are required, the cylinder pushes the lower telescopic rod to extend, causing the punch to move downward and close with the first or second die. After molding is completed, the cylinder drives the telescopic rod to retract, causing the punch to return to its original position, which facilitates the exchange of die positions or the removal of molding silicone, ensuring that the punch lifting and lowering action is stable and controllable.

[0010] Preferably, guide rods are installed on both the left and right sides of the upper surface of the punch, the guide rods pass through the top plate, and the guide rods are slidably connected to the top plate.

[0011] With the above structural design, when the cylinder drives the punch to rise and fall through the telescopic rod, the guide rod slides vertically along the top plate, restricting the movement trajectory of the punch, preventing the punch from deviating or tilting, ensuring that the punch can accurately close with the first and second dies, and avoiding defects in silicone molding caused by misalignment.

[0012] Preferably, the punch is located directly above the first die, the first die and the second die are connected below each other by a connecting frame, a servo motor is installed on the lower surface of the base, and the servo motor is connected to the connecting frame above the base by an output shaft, and the connecting frame is integrally cast.

[0013] With the above structural design, the punch is initially located directly above the first die, ensuring accurate initial mold closing; the connecting frame is integrally cast to improve structural strength; when the servo motor is started, its output shaft drives the connecting frame to rotate, causing the first die and the second die to exchange positions. The formed die is moved to the cooling zone, and the empty die is moved to the forming zone, realizing parallel "forming-cooling" operations and reducing part removal waiting time; the connecting frame also provides stable support for the two dies, preventing the dies from shaking during exchange or forming.

[0014] Preferably, the cooling fan is located above the second concave mold and the cooling water pipe, and the cooling water pipe has an S-shaped structure design.

[0015] With the above structural design, the S-shaped heat dissipation pipe can expand the heat dissipation area. When the molded cavity moves to this point, the cooling fan blows downwards, and the airflow is cooled by passing through the S-shaped heat dissipation pipe, forming cold air that acts on the medical silicone in the cavity, accelerating the cooling and curing of the silicone. At the same time, the S-shaped heat dissipation pipe is close to the cavity, and assists in cooling through heat conduction, improving the cooling efficiency.

[0016] Preferably, a water pump is installed on the front surface of the cold water tank, and an outlet pipe and an inlet pipe are installed above and to the right of the water pump, respectively. The outlet pipe is connected to the heat dissipation water pipe, and the inlet pipe is connected to the cold water tank.

[0017] With the above structural design, after the water pump is started, the inlet pipe on its right side draws cold water from the cold water tank, and then delivers the cold water to the S-shaped heat dissipation pipe through the outlet pipe above. The cold water flows in the heat dissipation pipe, absorbs the heat from the concave mold and silicone, and then flows back to the cold water tank, forming a closed-loop water circulation, ensuring that the heat dissipation pipe continues to maintain a low temperature and providing a stable cold source for the cooling process.

[0018] Preferably, the distance between the heat dissipation water pipe and the second concave mold does not affect the demolding of the medical silicone material inside the second concave mold. A semiconductor cooling chip is installed on the cold water tank, with the cold end of the semiconductor cooling chip in contact with the cold water tank and the heat dissipation end located outside the cold water tank.

[0019] With the above structural design, the distance between the heat dissipation water pipe and the second concave mold is designed to ensure heat dissipation effect without hindering the demolding of silicone in the second concave mold, and to avoid the cooling structure affecting the subsequent part removal operation; the semiconductor cooling chip on the cold water tank works continuously, with its cold end in contact with the cold water tank to cool the water in the tank, and the heat dissipation end located outside the cold water tank to expel heat from the equipment, ensuring the stability of the cold water temperature in the tank and ensuring the cooling effect of the cooling water circulation.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the molding equipment for this high-performance medical silicone material: 1. Alternating operation of dual concave dies enables parallel "forming-cooling" processes, improving production efficiency. The equipment uses a servo motor on the lower surface of the base to drive the connecting frame, which in turn moves the first and second concave dies alternately to the area directly below the punch. After the first concave die is formed, the servo motor moves it to the cooling area on the right side, while the empty second concave die moves to the forming area. Under the action of the punch, the next batch of forming operations can be started immediately. Production can continue without waiting for the previous batch of silicone to cool and be removed, which greatly reduces the equipment's idle time and improves the output efficiency per unit time. 2. Highly efficient cooling and demolding compatibility ensure molding quality and ease of operation. In the right-side cooling zone, the cooling fan on the lower surface of the top plate blows air downwards. The airflow is delivered to the S-shaped cooling water pipes via the cold water tank and then cooled, forming cold air that quickly lowers the temperature of the molding silicone. The semiconductor cooling chip on the cold water tank ensures a stable cooling water temperature, and the S-shaped cooling water pipes expand the heat dissipation area, resulting in high cooling efficiency. At the same time, the distance between the cooling water pipes and the second cavity mold is designed not to obstruct the demolding of the silicone, ensuring rapid curing of the silicone while avoiding the cooling structure from affecting subsequent part removal operations, thus balancing quality and convenience.

[0024] Please see Figures 1-5This utility model provides a technical solution: a high-performance medical silicone material molding equipment, including a base 1, a support plate 2, a top plate 3, a telescopic rod 4, a punch 5, a cylinder 6, a guide rod 7, a first die 8, a second die 9, a connecting frame 10, a servo motor 11, a cooling fan 12, a cold water tank 13, a cooling water pipe 14, a water pump 15, a water outlet pipe 16, and a water inlet pipe 17.

A punch 5 is installed below the top plate 3 via the telescopic rod 4. A cylinder 6 is installed on the upper surface of the top plate 3, and the lower part of the cylinder 6 is connected to the telescopic rod 4. When mold closing and molding are required, the cylinder 6 pushes the telescopic rod 4 below to extend, causing the punch 5 to move downward to close with the first die 8 or the second die 9. After molding is completed, the cylinder 6 drives the telescopic rod 4 to retract, causing the punch 5 to return to its original position, facilitating the exchange of die positions or the removal of molding silicone, ensuring that the lifting and lowering action of the punch 5 is stable and controllable. Guide rods 7 are installed on both the left and right sides of the upper surface of the punch 5. The guide rods 7 pass through the top plate 3 and are slidably connected to the top plate 3. When the cylinder 6 is in operation, the top plate 3 can be closed. When the telescopic rod 4 drives the punch 5 to rise and fall, the guide rod 7 slides vertically along the top plate 3, restricting the movement trajectory of the punch 5, preventing the punch 5 from shifting or tilting, and ensuring that the punch 5 can accurately close with the first die 8 and the second die 9, avoiding defects in silicone molding caused by misalignment. The first die 8 and the second die 9 are respectively provided on the left and right sides of the upper surface of the base 1. The punch 5 is located directly above the first die 8. The lower parts of the first die 8 and the second die 9 are connected by a connecting bracket 10. A servo motor 11 is installed on the lower surface of the base 1, and the servo motor 11 is connected by an input... The output shaft is connected to the connecting frame 10, which is integrally cast. The punch 5 is initially located directly above the first die 8 to ensure accurate initial mold closing. The integral casting of the connecting frame 10 enhances structural strength. The servo motor 11 is started, and its output shaft drives the connecting frame 10 to rotate, causing the first die 8 and the second die 9 to exchange positions. The formed die is moved to the cooling zone, and the empty die is moved to the forming zone, realizing parallel "forming-cooling" operations and reducing part removal waiting time. The connecting frame 10 also provides stable support for the two dies, preventing the dies from shaking during exchange or forming.

[0025] A cooling fan 12 is installed on the right side of the lower surface of the top plate 3. The cooling fan 12 is located above the second cavity mold 9 and the cooling water pipe 14, and the cooling water pipe 14 has an S-shaped structure design, which can increase the heat dissipation area. When the molded cavity mold moves to this location, the cooling fan 12 blows air downwards, and the airflow is cooled by passing through the S-shaped cooling water pipe 14, forming cold air that acts on the medical silicone inside the cavity mold, accelerating the cooling and curing of the silicone. The S-shaped cooling water pipe 14 is also close to the cavity mold, through... Heat conduction-assisted cooling improves cooling efficiency. A cold water tank 13 is installed on the right side of the right support plate 2, and a heat dissipation pipe 14 is installed on the left side of the cold water tank 13. A water pump 15 is installed on the front surface of the cold water tank 13, and an outlet pipe 16 and an inlet pipe 17 are installed above and to the right of the water pump 15, respectively. The outlet pipe 16 is connected to the heat dissipation pipe 14, and the inlet pipe 17 is connected to the cold water tank 13. After the water pump 15 is started, the inlet pipe 17 on its right side draws cold water from the cold water tank 13, and then through the top... The square water outlet pipe 16 delivers cold water to the S-shaped heat dissipation water pipe 14. The cold water flows inside the heat dissipation water pipe 14, absorbs heat from the concave mold and silicone, and then flows back to the cold water tank 13, forming a closed-loop water circulation. This ensures that the heat dissipation water pipe 14 maintains a low temperature, providing a stable cold source for the cooling process. The distance between the heat dissipation water pipe 14 and the second concave mold 9 does not affect the demolding of the medical silicone material inside the second concave mold 9. A semiconductor cooling chip is installed on the cold water tank 13. The cold end of the semiconductor cooling chip is in contact with the cold water tank 13, and the heat dissipation end is located outside the cold water tank 13. The distance between the heat dissipation water pipe 14 and the second concave mold 9 is designed to ensure heat dissipation without hindering the demolding of the silicone inside the second concave mold 9, thus avoiding the cooling structure from affecting subsequent part removal operations. The semiconductor cooling chip on the cold water tank 13 works continuously. Its cold end is in contact with the cold water tank 13 to cool the water in the tank, and its heat dissipation end is located outside the cold water tank 13 to expel heat from the equipment, ensuring a stable temperature of the cold water in the tank and guaranteeing the cooling effect of the cooling water circulation.

[0026] Working principle: When using this high-performance medical silicone material molding equipment, firstly, the medical silicone raw material is placed into the first concave mold 8 on the left side of the upper surface of the base 1.

[0027] The cylinder 6 on the upper surface of the top plate 3 is activated. The cylinder 6 pushes the telescopic rod 4 below to extend, causing the punch 5 to move downward. The guide rods 7 on the left and right sides of the upper surface of the punch 5 pass through the top plate 3 and slide along the top plate 3, limiting the offset of the punch 5 and ensuring that the punch 5 and the first die 8 are accurately molded together, thus completing the silicone molding.

[0028] After molding, cylinder 6 drives telescopic rod 4 to retract, causing punch 5 to return to its original position. The servo motor 11 on the lower surface of base 1 is started, and its output shaft drives the connecting frame 10 below the first die 8 and the second die 9 to rotate, moving the molded first die 8 to the right cooling area. At the same time, the empty second die 9 is moved directly below punch 5. Then the mold closing action is repeated to mold the medical silicone material in the second die 9, realizing "molding-molding" in parallel.

[0029] The cooling zone operation is started simultaneously: the cooling fan 12 on the right side of the lower surface of the top plate 3 is started, blowing air downwards; at the same time, the water pump 15 on the front surface of the cold water tank 13 on the right side of the right support plate 2 is started. The water pump 15 draws cold water from the cold water tank 13 through the right inlet pipe 17 and delivers it to the S-shaped heat dissipation water pipe 14 on the left side of the cold water tank 13 through the upper outlet pipe 16; the cold water flows in the heat dissipation water pipe 14, and the airflow of the cooling fan 12 is cooled by the S-shaped heat dissipation water pipe 14, forming cold air that acts on the silicone in the first cavity mold 8, accelerating its cooling and curing; the semiconductor cooling chip on the cold water tank 13 continuously cools the cold water to ensure the cooling effect; and the distance between the heat dissipation water pipe 14 and the second cavity mold 9 does not affect the subsequent demolding.

[0030] After the medical silicone in the first concave mold 8 has cooled and the medical silicone in the second concave mold 9 has formed, the formed silicone in the first concave mold 8 is removed, and the servo motor 11 is started again to change the position of the concave molds, cooling the medical silicone in the second concave mold 9. This cycle is repeated to achieve continuous and efficient production, thus completing a series of tasks. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
