Description

Technical Field

[0001] This utility model relates to the field of silicone rubber preparation technology, specifically to a silicone rubber preheating and cooling device. Background Technology

[0002] The Influence of Silicone Preheating and Cooling on Molding Temperature: Silicone preheating is a crucial step in the injection molding process of medical-grade silicone. Preheating improves the fluidity of the silicone, facilitating rapid mold filling and reducing air bubble formation. Simultaneously, preheating reduces the temperature gradient of the silicone within the mold, minimizing internal stress. Generally, the preheating temperature needs to be 20-30 degrees Celsius higher than the molding temperature to ensure the silicone reaches its ideal flow state before injection. The cooling process is equally important, preventing over-curing of the silicone within the mold, which can lead to product deformation or cracking.

[0003] Currently, traditional silicone rubber preheating and cooling devices generally suffer from several problems that urgently need to be addressed. From an energy utilization perspective, most preheating and cooling devices operate independently, and energy cannot be effectively recycled. The preheating mechanism typically uses electric heating or similar methods, with the waste heat directly released into the environment; the cooling mechanism mostly relies on refrigeration equipment, and there is no energy exchange mechanism between the two, resulting in high energy consumption throughout the entire processing. Utility Model Content

[0004] The purpose of this invention is to provide a silicone rubber preheating and cooling device to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A silicone rubber preheating and cooling device includes a storage mechanism, a preheating mechanism, and a cooling mechanism.

[0007] Furthermore, the storage mechanism includes a liquid storage tank with an insulation plate installed inside. This insulation plate divides the tank into a heating chamber and a cooling chamber, effectively separating the heating and cooling functions and preventing mutual interference. The heating chamber contains a heating element for heating the water, which includes an inner tank installed within the heating chamber. Four sets of heaters are installed on the outer wall of the inner tank. The cooling chamber contains a cooling element for cooling the water, which includes a spiral-shaped cooling pipe located inside the cooling chamber. A chiller unit is located outside the liquid storage tank, and the two ends of the cooling pipe are connected to the output and input ends of the chiller unit, respectively. The arrangement of the heating and cooling elements, utilizing water as the heat exchange medium, provides a stable heat and cold source for the preheating and cooling processes. The design of the inner tank and the spiral cooling pipe increases the heat exchange area and improves heating and cooling efficiency. The cooperation between the chiller unit and the cooling pipe allows for precise control of the water temperature within the cooling chamber, ensuring effective cooling. This design enables the initial circulation of energy within the device, laying the foundation for the efficient operation of subsequent preheating and cooling mechanisms, reducing dependence on external energy sources, and lowering energy consumption.

[0008] Furthermore, the preheating mechanism includes a preheating barrel, inside which a storage component slides for storing silicone rubber. The storage component includes a storage tank, the top surface of which is fitted with a retaining ring. The top surface of the preheating barrel has a retaining groove, and the retaining ring engages with the retaining groove. The storage tank slides within the preheating barrel. This sliding connection between the storage component and the preheating barrel facilitates the placement of silicone rubber into the preheating barrel for preheating and also makes it easy to remove it after preheating, resulting in convenient and efficient operation. A first feeding component connects the preheating barrel and the heating element. The first feeding component includes a first water inlet pipe, the two ends of which are respectively connected to the preheating barrel and the inner barrel. A first valve body is connected to the outside of the first water inlet pipe. A first discharge component connects the preheating tank and the cooling component. The first discharge component includes a first water outlet pipe, with both ends of the first water outlet pipe connected to the preheating tank and the cooling chamber, respectively. A second valve body is connected to the outside of the first water outlet pipe. The configuration of the first feed component and the first discharge component, as well as the control of the valve body, can precisely control the inflow and outflow of hot water, achieving precise control of the silicone rubber preheating process. By introducing hot water from the heating chamber into the preheating tank, the silicone rubber is preheated, improving its fluidity and reducing the temperature gradient of the silicone rubber within the mold, thus reducing the generation of internal stress in the mold. After preheating, the cooled water in the preheating tank is discharged into the cooling chamber, realizing the recycling of water resources.

[0009] Furthermore, a cooling mechanism includes a support platform with a fixing member mounted on its top surface. The fixing member has a fixing cavity on its top surface for fixing the mold. The fixing cavity is designed to stably fix the mold. The fixing member has an internal cavity, and a second feeding member connects the cavity and the cooling component. The second feeding member includes a second water inlet pipe. A first pump is mounted on the outside of the fixing member. The two ends of the second water inlet pipe are respectively connected to the input end of the first pump and the cooling cavity. A third valve body connects to the outside of the second water inlet pipe. The output end of the first pump is connected to the cavity. A second discharge member connects the cavity and the heating component. The second discharge member includes a... The second water outlet pipe has a second pump installed on the top surface of the storage tank. The two ends of the second water outlet pipe are connected to the input end and the cavity of the second pump, respectively. The output end of the second pump is connected to the inner tank. The setting of the second feeding component and the second discharging component, together with the pump and valve body, realizes the circulation of cold water in the cooling chamber and the recovery of heat. By introducing the cold water in the cooling chamber into the cavity of the fixing component, the silicone rubber in the mold is cooled, which effectively prevents the silicone from over-curing in the mold, avoids product deformation or cracking, and improves product quality. After cooling, the heated water in the cavity is pumped back into the heating chamber, realizing the circulation of water resources and energy, further reducing energy consumption and improving energy utilization efficiency.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This silicone rubber preheating and cooling device achieves effective energy recycling during the preheating and cooling process, reducing dependence on external energy and lowering production costs. By precisely controlling the preheating and cooling process, the quality of silicone rubber products is improved, and defects such as product deformation and cracking are reduced. The rational structural design of each component facilitates operation and improves production efficiency. The storage mechanism, preheating mechanism, and cooling mechanism work together to form a highly efficient and energy-saving silicone rubber preheating and cooling system, which has promising application prospects.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a silicone rubber preheating and cooling device, comprising the following steps:

[0019] Before preheating the silicone rubber, check that all components of the device are operating normally. Ensure that the storage tank 1001 is leak-free, the insulation plate 1004 is securely installed, the inner tank 1005 in the heating chamber and the four sets of heaters 1006 on its outer wall are all functioning normally, the chiller unit 400 is operating stably, and the cooling pipe 1007 is not blocked. Simultaneously, check that the slots 2007 and retaining rings 2008 of the preheating tank 2001 and storage tank 2002 are matched, all pipe connections are tight, the first valve body 2006, second valve body 2004, and third valve body 3006 open and close normally, and the first pump and second pump 3004 operate normally. Place the silicone rubber to be preheated into the storage tank 2002 and gently push the storage tank 2002 to slide it within the preheating tank 2001 until the retaining ring 2008 engages with the slot 2007.

[0020] Heater 1006 is turned on to heat the water in the heating chamber. The inner tank 1005 effectively concentrates heat, and four sets of heaters 1006 are evenly distributed on the outer wall of the inner tank 1005, enabling rapid and uniform heating of the water to a preset temperature, assuming the preset temperature is 80℃. Once the water temperature reaches 80℃, the first valve 2006 is opened and the second valve 2004 is closed. The heated water in the heating chamber 1002 flows into the preheating tank 2001 through the first inlet pipe 2005. The hot water flows around the storage tank 2002 within the preheating tank 2001, preheating the silicone rubber inside the storage tank 2002 through heat conduction. During preheating, the silicone rubber gradually heats up, its fluidity continuously improves, and its internal stress gradually decreases, preparing it for subsequent mold filling.

[0021] After a period of preheating, once the silicone rubber reaches a suitable preheating temperature, which is measured by a thermometer, the first valve 2006 is closed and the second valve 2004 is opened. At this time, the hot water in the preheating tank 2001, whose temperature has decreased, flows into the cooling chamber 1003 through the first outlet pipe 2003, achieving water recycling. The coolant in the spiral cooling pipe 1007 within the cooling chamber cools the incoming hot water under the action of the chiller unit 400, preparing it for subsequent cooling processes.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a silicone rubber preheating and cooling device, comprising the following steps:

[0024] The mold containing the injected silicone rubber is placed in the fixing cavity 3007 on the top surface of the fixing component 3002, ensuring the mold is securely fixed. The coolant in the cooling pipe 1007, under the action of the chiller unit 400, has cooled the water in the cooling cavity 1003 to a suitable temperature, which is measured by a thermometer. Simultaneously, it is confirmed that all components of the second feeding and second discharging components, such as the second water inlet pipe 3005, the third valve body 3006, the first pump, the second water outlet pipe 3003, and the second pump 3004, are functioning normally.

[0025] Open the third valve body 3006 and start the first pump. Under the action of the first pump, the cold water in the cooling chamber 1003 flows through the second inlet pipe 3005 into the cavity 3008 inside the fixing component 3002. The cold water flows within the cavity 3008, carrying away the heat from the silicone rubber inside the mold and cooling the silicone rubber. Because the cooling pipe 1007 is spiral-shaped, the contact area with the water is increased, allowing the water in the cooling chamber 1003 to be cooled quickly and efficiently, thus ensuring the cooling effect on the silicone rubber, effectively preventing the silicone rubber from over-curing inside the mold, and avoiding defects such as product deformation or cracking.

[0026] After a period of cooling, once the silicone rubber has cooled to a suitable temperature (measured by the temperature sensor integrated into the mold), the third valve 3006 is closed, stopping the first pump. At this point, the second pump 3004 is turned on, and the water in the cavity 3008, whose temperature has risen, is pumped into the inner tank 1005 through the second outlet pipe 3003. This heated water can then be used as a heating element in subsequent heating processes, achieving water and energy recycling and reducing energy consumption throughout the entire processing.
