Technical Field
[0001] This utility model relates to the technical field of silicone part molding equipment, specifically to an intelligent temperature control system for automated silicone part molding equipment. Background Technology
[0002] Silicone parts are a type of multifunctional material product, mainly derived from quartz stone. They are environmentally friendly, safe, non-toxic, heat-resistant, soft, comfortable, and easy to clean. Their core component is silicon dioxide, which forms an amorphous network structure with high adsorption, thermal stability, and chemical inertness. During the processing of silicone parts, the silicone raw material is placed in a molding mold and heated at high temperature to cause the rubber molecules to undergo a crosslinking reaction, transforming from a linear structure to a network structure, thereby obtaining products with the desired physical properties.
[0003] In the existing process of processing silicone parts, silicone raw materials are placed inside the molding mold, and then the mold is heated to promote the formation of a three-dimensional network structure of silicon molecular chains. Then, cooling components (such as water cooling) are used to cool and shape the silicone parts, thereby forming silicone parts of a specific shape.
[0004] Existing intelligent temperature control systems for automated silicone part molding equipment heat the silicone part, then cool it down using cooling components before reheating the equipment. This process results in significant heat loss, and the equipment must be heated from the cooled temperature again, increasing energy consumption. To address this, we propose an intelligent temperature control system for automated silicone part molding equipment. Utility Model Content

[0020] 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.
[0021] Please see Figure 1-3This embodiment provides a technical solution: an intelligent temperature control system for automated silicone molding equipment, including a housing 1. A protective door 2 is hinged to the front surface of the housing 1. A heat-resistant rubber sealing gasket 9 (optionally made of asbestos rubber) is fixedly connected to the rear surface of the protective door 2. A partition 3 is provided on the lower side of the interior of the housing 1, and a heat storage chamber 4 is located above the partition 3. A heating chamber 5 is fixedly connected to the interior of the housing 1. Evenly distributed baffles 7 are fixedly connected to the left and right surfaces of the interior of the heating chamber 5. Opening the protective door 2 allows the mold containing silicone raw material to be placed horizontally... Between the upper surfaces of two adjacent baffles 7, the protective door 2 is then closed. A microcontroller 13 is installed on the outside of the housing 1. The input terminal of the microcontroller 13 is electrically connected to an external power source. The input terminals of solenoid valve 1 82 and solenoid valve 2 86 are both electrically connected to the output terminal of the microcontroller 13. A heating wire 6 is fixedly connected to the rear surface of the interior of the heating chamber 5. Operating the microcontroller 13 activates the heating wire 6. After the heating wire 6 is energized, its temperature rises, heating the interior of the heating chamber 5, thereby heating the mold containing silicone raw material (heating temperature is 150℃-200℃). Temperature sensors 14, evenly distributed, are fixedly connected to the upper surface of heating chamber 5 (the temperature sensors 14 are fixedly mounted using ceramic brackets to prevent damage to the temperature sensors 14 due to heat transfer). The detection ends of the temperature sensors 14 all extend into the interior of heating chamber 5. Each temperature sensor 14 is bidirectionally electrically connected to microcontroller 13. The input end of heating wire 6 is electrically connected to the output end of microcontroller 13. The detection ends of the temperature sensors 14 monitor the temperature inside heating chamber 5 and convert the monitored temperature data into electrical signals, which are then transmitted to microcontroller 13. 3. The temperature signal transmitted by the temperature sensor 14 is analyzed. When a specific temperature is reached, the microcontroller 13 controls the heating wire 6 to turn off. When the temperature is lower than a specific temperature, the microcontroller 13 controls the heating wire 6 to turn on, so that the silicone material is heated and expanded to form a shape. The lower surface of the partition 3 is fixedly connected to the air inlet pipe 10, and the lower surface of the heating chamber 5 is fixedly connected to the air inlet pipe 2 11. The air inlet pipe 10 and the air inlet pipe 2 11 are both connected in series with the solenoid valve 3 12. The input end of the solenoid valve 3 12 is electrically connected to the output end of the microcontroller 13. The system also includes a heat recovery mechanism 8.
[0022] The heat recovery mechanism 8 includes a three-way valve 81, a solenoid valve 82, a check valve 83, a two-way valve 85, and a solenoid valve 86. The three-way valve 81 is fixedly connected to the upper surface of the heating chamber 5. Solenoid valves 82 are fixedly connected to both ends of the three-way valve 81, and check valves 83 are fixedly connected to both sides of the three-way valve 81. The two-way valve 85 is fixedly connected to the rear surface of the housing 1. The left end of the two-way valve 85 is connected to the heat storage chamber 4, and the right end is connected to the heating chamber 5. Solenoid valves 86 are fixedly connected to both sides of the interior of the two-way valve 85. The heat recovery mechanism 8 also includes a vacuum pump 84, which is located at the rear of the housing 1. The air inlet of the vacuum pump 84 is connected to the three-way valve 85. The rear end is fixedly connected, and the input end of the vacuum pump 84 is electrically connected to the output end of the microcontroller 13. Afterwards, the silicone part needs to be cooled. To avoid uneven shrinkage due to excessive temperature difference between the inner and outer layers of the silicone part, the silicone part needs to be cooled in stages. At this time, the microcontroller 3 is operated to start the vacuum pump 84 and open the left solenoid valve 2 86, causing the vacuum pump 85 to run and extract the gas inside the heat storage chamber 4, creating a negative pressure inside the heat storage chamber 4. Then, the vacuum pump 85 and the left solenoid valve 2 86 are closed. At this time, the left solenoid valve 1 82 and the solenoid valve 3 12 inside the inlet pipe 2 11 are opened. The high-temperature gas inside the heating chamber 5 flows into the heat storage chamber 4 through the left end of the three-way valve 1 81 and the left one-way valve 83, while the external low-temperature gas flows through the inlet pipe 2 82 83. 11. The gas enters the lower part of the heating chamber 5 to balance the air pressure. Due to the low density of hot air, it flows upward into the heat storage chamber 4, thus storing the high-temperature gas inside the heating chamber 5 into the heat storage chamber 4. When the temperature sensor 14 detects that the temperature inside the heating chamber 5 has reached the slow cooling requirement (100℃-120℃), the solenoid valve 82 on the left side and the solenoid valve 12 inside the air inlet pipe 11 are closed to slowly cool the silicone part. After slow cooling for 10-20 minutes, the protective door 2 is opened, and the mold containing the silicone material is removed, thus rapidly cooling and molding the mold containing the silicone material. When it is necessary to reheat the mold containing the silicone material, the mold containing the silicone material is... Placed between the upper surfaces of two horizontally adjacent baffles 7, the protective door 2 is closed. The microcontroller 13 is operated to start the vacuum pump 84 and open the right solenoid valve 2 86, causing the vacuum pump 85 to run and extract the gas inside the heating chamber 5, creating a negative pressure inside the heating chamber 5. Then, the vacuum pump 85 and the right solenoid valve 2 86 are closed. At this time, the right solenoid valve 1 82 and the solenoid valve 3 12 inside the air inlet pipe 10 are opened, allowing the high-temperature gas inside the heat storage chamber 4 to flow into the heating chamber 5 through the right one-way valve 83 and the right end of the three-way valve 1 81. The low-temperature gas from outside enters the lower part of the heat storage chamber 4 through the air inlet pipe 10, thereby balancing the gas pressure. In this way, the high-temperature gas inside the heat storage chamber 4 is recovered and reused, thus saving energy.
[0023] The working principle of the intelligent temperature control system for automated silicone part molding equipment provided by this utility model is as follows: When using this intelligent temperature control system for temperature control of silicone part molding, open the protective door 2, place the mold containing silicone raw material between the upper surfaces of two horizontally adjacent baffles 7, then close the protective door 2, operate the microcontroller 13, and start the heating wire 6. After the heating wire 6 is energized, its temperature rises, heating the inside of the heating chamber 5, thereby heating the mold containing silicone raw material (heating temperature is 150℃-200℃). The detection end of the temperature sensor 14 monitors the temperature inside the heating chamber 5 and converts the monitored temperature data into an electrical signal, which is then transmitted to the microcontroller 13. The microcontroller 13 then processes the temperature... The temperature signal transmitted by sensor 14 is analyzed. When a specific temperature is reached, microcontroller 13 controls heating wire 6 to turn off. When the temperature is lower than a specific temperature, microcontroller 13 controls heating wire 6 to turn on, causing the silicone material to expand and mold. Afterwards, the silicone part needs to be cooled. To avoid uneven shrinkage due to excessive temperature difference between the inner and outer layers of the silicone part, the silicone part needs to be cooled in stages. At this time, microcontroller 3 is operated to start vacuum pump 84 and open solenoid valve 2 86 on the left side, so that vacuum pump 85 runs to extract the gas inside heat storage chamber 4, creating a negative pressure inside heat storage chamber 4. Then, vacuum pump 85 and solenoid valve 2 86 on the left side are closed. At this time, solenoid valve 1 82 on the left side and solenoid valve 3 12 inside air inlet pipe 2 11 are opened to heat the high-temperature gas inside heating chamber 5. The gas flows into the heat storage chamber 4 through the left end of the three-way valve 81 and the one-way valve 83 on the left side. External low-temperature gas enters the lower part of the heating chamber 5 through the air inlet pipe 11, thus balancing the air pressure. Due to the low density of hot air, it flows upwards into the heat storage chamber 4, thereby storing the high-temperature gas inside the heating chamber 5. When the temperature sensor 14 detects that the temperature inside the heating chamber 5 has reached the slow cooling requirement (100℃-120℃), the left solenoid valve 82 and the solenoid valve 12 inside the air inlet pipe 11 are closed to allow for slow cooling of the silicone parts. After slow cooling for 10-20 minutes, the protective door 2 is opened, and the mold containing the silicone material is removed, allowing for rapid cooling of the mold. When the mold containing silicone material needs to be heated again, place the mold between the upper surfaces of two horizontally adjacent baffles 7, close the protective door 2, operate the microcontroller 13, start the vacuum pump 84 and open the right solenoid valve 2 86, causing the vacuum pump 85 to run and extract the gas inside the heating chamber 5, creating a negative pressure inside the heating chamber 5. Then close the vacuum pump 85 and the right solenoid valve 2 86. At this time, open the right solenoid valve 1 82 and the solenoid valve 3 12 inside the air inlet pipe 10, allowing the high-temperature gas inside the heat storage chamber 4 to flow into the heating chamber 5 through the right one-way valve 83 and the right end of the three-way valve 81. The low-temperature gas from outside enters the lower part of the heat storage chamber 4 through the air inlet pipe 10, thereby balancing the gas pressure.This method of recovering and reusing the high-temperature gas inside the thermal storage chamber 4 saves energy.
[0024] It is worth noting that the solenoid valve 82, solenoid valve 86, and solenoid valve 12 disclosed in the above embodiments are all ZCG15, the vacuum pump 84 is 2XZ-0.25, the microcontroller 13 is AT89S52, and the temperature sensor 14 is WZPK-221-C.
