Abstract
Description
Technical Field
[0001] This invention relates to the field of hot pressing mold technology, and more specifically to a hot pressing process mold for the continuous production of high-temperature resistant composite materials. Background Technology
[0002] Hot pressing molds are devices used to process raw materials (usually composite materials or resins) into specific shapes under high temperature and high pressure. This process is widely used in aerospace, automotive, electronics and other fields to manufacture high-performance materials and components. Most mainstream hot press machines on the market currently rely on table heating to conduct heat to the mold for hot pressing of raw materials. However, this table heating method may have the following problems when facing continuous production: 1. During continuous production, after the heated mold has completed hot pressing, it needs to be cooled to facilitate demolding. Then the worktable needs to be heated again to heat the mold. This heating-cooling-heating method not only occupies the press for a long time, but also easily causes energy waste. Furthermore, since the worktable heating usually requires a certain preheating time, it may further extend the production cycle, affect production efficiency, and is not conducive to continuous production. 2. The heating of the table surface relies on heat conduction to transfer heat to the mold. The heat transfer efficiency may be affected by the mold material, design and thickness, resulting in uneven heating. Hot spots or cold spots may appear in some areas of the mold, which may cause defects such as bubbles and cracks in the composite material during the curing process, affecting the molding quality of the product. 3. Currently, the highest hot pressing temperature of hot presses is directly proportional to their price (for example, the price of a 600℃ press is much higher than that of a 200℃ press). This is because higher-priced hot presses use better heating table materials. However, the high price may put financial pressure on small and medium-sized enterprises, making the return on investment unclear. For companies with limited budgets, this may be an unbearable economic burden. Therefore, it is necessary to invent a hot pressing process mold for the continuous production of high-temperature resistant composite materials. Summary of the Invention

Detailed Implementation
[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0016] like Figure 1 - Figure 11 and Figure 14 As shown, a hot pressing process mold for continuous production of high-temperature resistant composite materials includes an upper mold, a lower mold, and an external circulation system. The upper mold includes a movable top plate 141. A top plate input terminal 142 and a top plate output terminal 143 are installed in the center of the movable top plate 141. An upper closing mold 131 is installed at the bottom of the movable top plate 141. The upper closing mold 131 has an internal upper heating pipe 135 and a cooling pipe 138. The cooling pipe 138 is located below the upper heating pipe 135. Side connecting parts 151 are installed on both sides of the upper closing mold 131. Side input terminals 152 and side output terminals 153 are provided on the side connecting parts 151. The lower mold includes a base 111, with a base input terminal 112 and a base output terminal 113 installed in the center of the base 111. A lower mold 121 is installed on the top surface of the base 111. The lower mold 121 has a built-in lower heating tube 125. Airflow cooling devices are provided on both sides of the lower mold 121, and atomizing cooling devices are provided on the other two sides. The external circulation system includes a central control compartment 19, a heat transfer oil heating compartment 181, a compressor 184, a condenser 185, and a water tank 188. The output end of the compressor 184 is connected to the input end of the condenser 185.
[0017] In the above embodiments, it should be noted that by injecting high-temperature heat-conducting oil in the heat-conducting oil heating chamber 181 into the upper heating pipe 135 and the lower heating pipe 125, the upper mold 131 and the lower mold 121 are directly heated, thereby improving the heat conduction efficiency of the mold and making the heating of the mold more uniform, which effectively improves the production efficiency and the molding quality of the product. The distance from the cooling pipe 138 to the bottom of the upper mold 131 is less than the distance from the cooling pipe 138 to the upper heating pipe 135. After the first batch of material is molded, the lower part of the upper mold 131 is cooled first through the cooling pipe 138. Since the cooling pipe 138 is closer to the bottom of the upper mold 131, it will first cool the surface of the hot-pressed material before the upper mold 131 is bent and cooled. Then, the airflow cooling device is activated to blow air into the gap between the upper mold 131 and the lower mold 121, so that the upper mold 131 gradually separates from the upper surface of the hot-pressed material. Then, the atomizing cooling device is activated to concentrate cooling. The hot-pressed material on the top surface of the lower mold 121 is removed and demolded. Since the water temperature is evenly sprayed on the hot-pressed material, the hot-pressed material can be completely cooled before the lower mold 121 is completely cooled. This achieves the effect of targeted cooling and demolding of the hot-pressed material without completely cooling the upper mold 131 and the lower mold 121. This method has the least impact on the internal center temperature of the upper mold 131 and the lower mold 121, minimizes the heat loss of the mold itself, avoids energy waste, shortens the heating time, further improves production efficiency, and is conducive to continuous production. The advantage of using self-heating molds in this application is that higher temperature pressing can be achieved simply by changing the mold material. Compared to the entire heating table, the mold requires less material and has a lower cost, which helps reduce the operating cost of the equipment and alleviate the financial pressure on small and medium-sized enterprises. The central control compartment 19 is mainly used to control the related equipment in the heat transfer oil heating compartment 181, compressor 184, condenser 185, and water tank 188. The central control compartment 19 is equipped with: A PLC controller is used for the automated control of the overall system. It is responsible for monitoring and controlling the operation of each link. The PLC can automatically adjust the start and stop of the air pump and the opening and closing status of the valve according to the preset program and sensor feedback information. The PLC can also make logical judgments based on the data fed back by the sensor (such as temperature, pressure, flow rate, etc.) to decide when to turn on or off the air pump and valve. The instrument display uses an LCD screen or touch screen to display the system operating status, various parameters and alarm information in real time; The control panel includes various buttons and switches, allowing operators to manually control the equipment's start-up, shutdown, mode switching, etc. The data logging module is used to record operational data for analysis and subsequent statistics and reporting. It typically includes storage card or cloud storage functionality. The alarm system integrates an audible and visual alarm system to monitor the equipment's operating status in real time and can promptly alert the system in case of any abnormality. The communication module enables interconnection with other devices or systems, supports remote monitoring and management, and commonly uses communication protocols such as Modbus and RS485. A power management system is used to provide a stable power supply and ensure the safe operation of equipment; like Figure 3 - Figure 9 and Figure 14 As shown, a hot pressing process mold for continuous production of high-temperature resistant composite materials further includes an upper heating pipe 135 with an upper heating pipe input connector 132 and an upper heating pipe output connector 133 installed at both ends. The upper heating pipe input connector 132 is inserted into the top plate input terminal 142, and the upper heating pipe output connector 133 is inserted into the top plate output terminal 143. A heat transfer oil output pump 182 and a heat transfer oil return pump 183 are installed on the heat transfer oil heating chamber 181. The output end of the heat transfer oil output pump 182 is connected to the top plate through a conduit. The input terminal 142 and the heat transfer oil return pump 183 are connected to the top plate output terminal 143 through a conduit. The lower heating pipe 125 is equipped with a lower heating pipe input connector 122 and a lower heating pipe output connector 123 at both ends. The lower heating pipe input connector 122 is inserted into the base input terminal 112, and the lower heating pipe output connector 123 is inserted into the base output terminal 113. The base input terminal 112 is connected to the output end of the heat transfer oil output pump 182 through a conduit, and the base output terminal 113 is connected to the heat transfer oil return pump 183 through a conduit.
[0018] In the above embodiments, it should be noted that the heat transfer oil heating chamber 181 has a built-in heating resistor. Through the principle of resistance heating, heat is generated when current passes through the heating element, which heats the heat transfer oil to the required temperature. The heat transfer oil output pump 182 is started by the PLC controller in the central control compartment 19, and the high temperature heat transfer oil is injected into the upper heating pipe 135 through the top plate input terminal 142 and the upper heating pipe input connector 132 in sequence. The heat exchange is then completed through the upper heating pipe 135. After that, the heat transfer oil returns to the heat transfer oil heating chamber 181 through the upper heating pipe output connector 133, the top plate output terminal 143 and the heat transfer oil return pump 183 in sequence for reheating, so as to achieve the effect of heating the upper mold 131. Similarly, the heat transfer oil output pump 182 is started by the PLC controller in the central control compartment 19, and the high temperature heat transfer oil is injected into the lower heating pipe 125 through the base input terminal 112 and the lower heating pipe input connector 122 in sequence. The heat exchange is then completed through the lower heating pipe 125. After that, the heat transfer oil returns to the heat transfer oil heating chamber 181 through the lower heating pipe output connector 123, the base output terminal 113 and the heat transfer oil return pump 183 in sequence for reheating, so as to achieve the effect of heating the lower mold 121.
[0019] like Figure 1 - Figure 3 , Figure 6 - Figure 10 and Figure 14 As shown, a hot pressing process mold for continuous production of high-temperature resistant composite materials further includes: a lower mold 121 with lower mold connecting parts 124 installed around its perimeter, the lower mold connecting parts 124 being fixedly connected to a base 111 by bolts; an upper mold 131 with upper mold connecting parts 134 installed around its perimeter, the upper mold connecting parts 134 being fixedly connected to a movable top plate 141 by bolts; side connecting parts 151 being installed on the upper mold connecting parts 134 on both sides of the upper mold 131 by bolts; and a cooling pipe inlet connector 136 and a cooling pipe outlet connector being installed at both ends of a cooling pipe 138. 137, Cooling pipe inlet connector 136 is inserted into side inlet terminal 152, Cooling pipe outlet connector 137 is inserted into side outlet terminal 153, Coolant outlet pump 186 is installed at the output end of condenser 185, Coolant outlet pump 186 is connected to side inlet terminal 152 through conduit, Coolant inlet pump 187 is installed at the input end of compressor 184, Coolant inlet pump 187 is connected to side outlet terminal 153 through conduit, Top plate 141 can be fixedly installed at the bottom of upper pressure plate of hydraulic press by bolts, Base 111 can be fixedly installed at the top of lower pressure plate of hydraulic press by bolts.
[0020] In the above embodiment, it should be noted that refrigerant is injected into the compressor 184. The compressor 184 compresses the refrigerant gas, increasing its pressure and temperature. Then, the condenser 185 cools the high-temperature and high-pressure refrigerant gas into a liquid, releasing heat. The PLC controller in the central control compartment 19 starts the coolant output pump 186, which injects the coolant in the condenser 185 into the cooling pipe 138 through the side input terminal 152 and the cooling pipe input connector 136. The coolant in the cooling pipe 138 absorbs heat and turns into gas. The coolant input pump 187 starts the gas in the cooling pipe 138 and reintroduces it into the compressor 184 through the cooling pipe output connector 137 and the side output terminal 153 for a new round of compression, so as to achieve the effect of cooling the lower part of the upper mold 131.
[0021] like Figure 1 , Figure 11 and Figure 12 As shown, a hot pressing process mold for continuous production of high-temperature resistant composite materials also includes an airflow cooling device comprising a cooling chamber 161, a chamber connector 164 fixedly installed at the bottom of the cooling chamber 161, the chamber connector 164 being fixedly installed on the top surface of the base 111 on both sides of the lower mold 121 by bolts, the air outlet of the chamber connector 164 being aligned with the top surface of the lower mold 121, an air inlet 163 being provided on the lower outer wall of the chamber connector 164, and a fan 162 being installed inside the chamber connector 164.
[0022] In the above embodiment, it should be noted that the fan 162 is electrically connected to the PLC controller and power supply in the central control compartment 19. The PLC controller in the central control compartment 19 controls the start of the fan 162 to draw air from the air inlet 163 and then blow it out, so as to quickly reduce the temperature of the upper surface of the hot-pressed material and assist the separation of the upper mold 13 from the upper surface of the hot-pressed material.
[0023] like Figure 1 , Figure 11 , Figure 13 and Figure 14 As shown, a hot pressing process mold for continuous production of high-temperature resistant composite materials also includes an atomizing cooling device comprising a conveyor frame connector 174. The conveyor frame connector 174 is fixedly installed on the top surface of the base 111 on both sides of the lower mold 121 by bolts. A conveyor frame 171 is installed on the top surface of the conveyor frame connector 174. Several atomizing nozzles 172 are provided on the side of the conveyor frame 171 near the lower mold 121. A water inlet terminal 173 is installed on the outside of the conveyor frame connector 174. The output end of the water inlet terminal 173 is connected to the input end of the conveyor frame 171. A water pump 189 and a water injection pipe are installed on a water tank 188. The output end of the water pump 189 is connected to the input end of the water inlet terminal 173 through a conduit.
[0024] In the above embodiment, it should be noted that water is injected into the water tank 188 through the water injection pipe, and then the PLC controller in the central control compartment 19 starts the water pump 189 to inject the water in the water tank 188 into the conveyor frame 171 through the water inlet terminal 173, and then sprayed out from the atomizing nozzle 172 on the surface of the conveyor frame 171, so as to achieve the effect of spraying water mist onto the upper surface of the hot pressing material and quickly cooling the hot pressing material.
[0025] The process of using this invention is as follows: Those skilled in the art place the raw material on top of the lower mold 121, start the hydraulic press to drive the upper mold 131 downwards to press the raw material. Then, the PLC controller in the central control compartment 19 starts the heat transfer oil output pump 182, injecting high-temperature heat transfer oil sequentially through the top plate input terminal 142 and the upper heating pipe input connector 132 into the upper heating pipe 135. Simultaneously, the PLC controller in the central control compartment 19 starts the heat transfer oil output pump 182, injecting high-temperature heat transfer oil sequentially through the base input terminal 112 and the lower heating pipe input connector 122 into the lower heating pipe 125, thereby directly heating the upper mold 131 and the lower mold 121. After the material is hot-pressed and formed, the PLC controller in the central control compartment 19 starts the coolant output pump 186, injecting the coolant in the condenser 185 sequentially through the side input terminal 152 and the coolant pipe input connector. Cooling liquid is injected into cooling pipe 138. The coolant in cooling pipe 138 absorbs heat and turns into gas, cooling the lower part of upper mold 131. The hydraulic press is started to drive upper mold 131 to separate upwards. At the same time, the PLC controller in the central control room 19 controls the start of fan 162 to draw air from air inlet 163 and blow it out to quickly reduce the surface temperature of the hot-pressed material and assist the upper mold 13 in separating from the surface of the hot-pressed material. After the upper mold 13 and the hot-pressed material are completely separated, the PLC controller in the central control room 19 starts the delivery water pump 189 to inject water from water tank 188 into delivery frame 171 through water inlet terminal 173. The water is then sprayed out from atomizing nozzle 172 on the surface of delivery frame 171 to quickly cool the hot-pressed material. Then, the technicians remove the hot-pressed material, put in new raw materials, and repeat the above operation to carry out continuous hot pressing of materials.
[0026] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
