由於各冷卻分流閥32皆具備獨立的開閉功能，由一控制主機所控 制，因此各冷卻分流閥32可分別被獨立地切換為開啟或是關閉。當成 形模具10局部溫度已經降低到開模溫度以下後，控制主機控制對應該 局部部位之冷卻分流閥32關閉，使冷卻流體不再進入對應的通道14 冷卻該局部區域，時’由躲浦314所能$送的冷卻紐最大總流 量為固定值，因此當任一通道14之冷卻流體被冷卻分流閥32阻斷時， ® 被阻斷的冷卻流體會被平均分配到其他通道14,使其他通道14中的冷 卻流體的流量提升’增加成職具1〇其餘部位的冷卻速率，因此可以 加速成形模具10之整體溫度降溫至開模溫度的速率。此外，各冷卻分 流閥32與通道14之間更設置一冷卻逆止閥322，用以供高冷卻流體單 向地通過’限定冷卻流體單向地由冷卻流體源3〇流向成形模具1〇之 通道14 ’而不會逆向流動。冷卻逆止閥322避免泵浦314停止運轉後， 因虹吸現象致使冷卻流體由冷卻流體回收裝置6〇逆向進入冷卻流體源 30中。 12 201012627 也就是說’由於模穴13型態的影響，成形模具10各部位的肉厚 會不一致。在局部冷卻功率一致的前提下，成形模具10之各部位降溫 的速率也不一致，部分區域會較早降溫至開模溫度。本發明個別切換 不同通道14中的冷卻流體，阻斷冷卻流體繼續冷卻已經降溫到達開模 溫度的局部區域，而力口速其他局部區域的冷卻速率，以縮短等待冷卻 所需要的時間。 局溫流體源提供之高溫流體於塑膠液注塑於成形模具10之前，預 ❿ 先將成賴具10加熱至相對高溫之工作温度，因此於塑驗被注塑於 成形模具10之後’高溫之成形模具10避免塑膠液迅速降溫固化。同 時維持高溫的塑膠液具備低黏滯係數，加速塑膠液流動填充於模穴 13 ’確保塑膠液充滿模穴13以減少空穴現象發生。冷卻流體源3〇快

Description of the Invention: [Technical Field] The present invention relates to a rapid heating and cooling forming system, and more particularly to a rapid cooling forming system capable of redistributing heating fluid and cooling fluid flow to accelerate heating and cooling of a forming mold rate. [Prior Art] The injection molding process mainly includes two steps of injecting a plastic liquid into a mold and cooling the mold to a mold opening temperature. During the injection of the plastic liquid into the mold, the plastic liquid must flow sufficiently in the cavity to fill the entire tank. In order to reproduce the miscellaneous samples, it is best to maintain the average/m degree above the melting temperature during the filling process. For highly viscous plastic fluids, such as thermoplastics, the temperature can be increased to lower the viscosity coefficient to improve fluidity. Therefore, before the plastic liquid is injected into the mold, it must be heated to a relatively high temperature to avoid the secret. The temperature of the plastic liquid will flow slowly, and the velocities will be blocked. Heating the plastic to a relatively high temperature means that the plastic knees must be held for a relatively long period of time in the injection structure and injected at a lower flow rate, thus extending the injection rate of the plastic liquid. After the plastic liquid is filled in the mold, the plastic liquid and the mold must be cooled to the softening temperature of the mold to be taken out. The plastic is formed. The softening temperature is usually below 8 degrees Celsius. Cooling the mold takes a long time to wait during the natural cooling process. Referring to "Figure 1" and "Figure 2", for the main + injection of plastic injection molding, the conventional technology proposes a kind of rapid heating and cooling forming, including mold 丨, high temperature base steam source 2, cooling fluid body Source 3, and high ink gas source 4. The inside of the mold i is provided with a pass 201012627 which is bent and passed through the inside of the mold to pass the fluid. The rapid heating and cooling forming system first supplies high temperature steam to the steaming source 2, and passes through the channel ia to heat the mold 1 with high temperature steam to heat the mold 1 to a relatively high temperature. The mold 1 is then clamped to the high temperature plastic test by the injection molding mechanism. · The high temperature of σ heat is difficult to transfer the liquid in the process of injection molding. After adding the thief to the thief, the Xiaojia plastic-free plastic is exposed to the low-temperature mold 1 and cured early. After the plastic injection liquid is completely injected, the cooling fluid source 3 is supplied with a low-temperature cooling fluid, such as cooling water, into the passage, and the mold is forcedly cooled, and the temperature of the isotropic mold 1 is rapidly lowered to the temperature. After passing through the high-temperature fluid or the cold part Zhao (after completion of heating and cooling), the ramp is fed with the high-pressure and high-pressure gas supplied by the high-pressure gas source 4, and the silk fluid of the young passage k towel avoids the residual fluid from affecting the heating. Or cooling effect. In this rapid heating and cooling forming system, the mold is firstly heated; the main plastic is preheated and forced to cool after injection molding, thereby greatly shortening the time required for injection molding and cooling of the plastic φ forming work towel. Since the shape 4 of the die eight varies, the thickness of the mold is different for each local region, and therefore the heat capacity of each partial region is also different. When the mold 1 is heated, the partial region ' of the mold 1 ® having a relatively low heat capacity is heated to a desired temperature relatively quickly, and the portion i of the mold having a relatively high heat capacity is warmed up to a desired temperature. The region where the temperature rises slowly causes the overall heating time to be prolonged, and during the heating of the local region where the temperature rise is slow, the localized region that has reached the predetermined temperature is still continuously heated, additionally consuming the energy required for heating. Similarly, in the cold n, the relatively low mold 丨 in the heat 4 will quickly lower the temperature to the job temperature, and the mold 1 with a relatively high heat capacity will lower the temperature to the job temperature later. The area of the _ _, resulting in the overall cut-time view length, and in the process of cooling the slow surface of the ship's surface, has reached the part of the mold opening temperature _ also women continue to cool the towel, the cake mixed cooling required 201012627 energy. Therefore, the rapid heating and cooling forming method has a surface energy for heating and cooling, which does not meet the requirement of reducing the energy loss and reducing the manufacturing cost. SUMMARY OF THE INVENTION In view of the above, the bribe-heating and cooling system and its forming mold can accelerate the heating and cooling rate and reduce the energy consumed by heating and cooling. In order to achieve the above object, the present invention provides a rapid heating and cooling forming system comprising a forming die, a high temperature fluid source, a cooling fluid source, and a draining device. The forming mold is used for plastic injection molding and cooling and forming, and the towel forming mold comprises a plurality of independent passages, each of which has an inlet end and an outlet end. The high temperature fluid source is used to provide a high temperature fluid, and the high temperature fluid source is connected to the inlet end of each channel through a plurality of heating diverter valves, so that the high temperature fluid enters each channel through each heating diverter valve, wherein each heating diverter valve is independently turned on or It is closed.

The cooling fluid source is connected to the inlet ends of the passages through a plurality of cooling diverter valves, so that the cooling fluid enters the passages through the respective heating diverter valves, wherein each cooling split system is independently turned on or It is closed. The draining device is configured to provide a high pressure gas to remove residual cooling fluid or high temperature fluid in each of the passages. By heating the diverter valve or cooling the diverter valve to open or close, to independently close the passage that has completed the heating or cooling operation, by redistributing the high temperature fluid and cooling fluid into the remaining channels, the heating or cooling rate of the remaining local area of the forming mold is accelerated. The main technical means of the present invention is to independently close the passage for completing the heating or cooling operation. According to the present invention, another rapid heating and cooling forming system is proposed, which comprises a forming mold, a 201012627 high temperature fluid source, a cooling fluid source, and a drainage liquid.

A source of cooling fluid is used to provide a cooling fluid, and a source of cooling fluid is coupled to the inlet ends of each passage to allow the passage of the cold fluid into the respective passages. The drain device is used to provide high pressure gas to remove residual cooling fluid or high temperature fluid in each channel. w The effect of the invention is to accelerate the heating or cooling process by redistributing the high temperature fluid and the cooling fluid into the channels without further increasing the total flow rate of the high temperature fluid and the cooling fluid, and reducing the energy required for heating or cooling. Consumption. [Embodiment] Referring to "Fig. 3" and "Fig. 4", a sequential heating and cooling forming system according to a first embodiment of the present invention includes a forming die, a high temperature fluid source, and a G cooling fluid. The source 30, the liquid discharge device 4, the high temperature fluid recovery device 5, and a cooling fluid recovery device 6A. Referring to "Fig. 3" and "Fig. 4", the forming mold 1 includes a male mold u and a female mold 12, and the male mold 11 and the female mold 12 are clamped to each other to form a cavity 13 for plastic molding. > liquid is; the main plastic is molded therein, and cooled and solidified. The splicing W has a plurality of independent flow passages 14, passing through one of the male mold 11 or the female mold 12 of the forming mold. The channel is supplied with two / fflt fluids, a cryogenic fluid, or a drying gas to add a ',, or a cold portion to the forming mold. The high temperature fluid, the low temperature fluid, or the dry gas enters the passage 14 via the human σ end 141 201012627. After passing through the forming mold 10, the passage is discharged from the outlet end 142. Each of the outlet ends 142 is connected in parallel to the safety valve 71, and is connected to the cooling fluid recovery unit 60 through the safety valve 71 or directly to the outside. The safety valve 71 is used to directly remove the excessive pressure in the channel when the system is abnormal, for example, if the system pressure is too red to automatically eliminate the abnormal problem. In the forming mold 10, corresponding to the inlet end 141 and the outlet end 142 of each channel 14, a mold temperature wire stomach 143 and a channel pressure surface U4 are respectively set, and the difference between the mold temperature and the temperature of the mold 143 is used to obtain a mold. Temperature Distribution. At the same time, the temperature difference between the mold temperature sensor 143 at the two ends of the passage 14 can also be used to analyze the heat exchange amount between the fluid in the passage 14 and the forming mold 1G. The passage pressure gauge head 144 (4) monitors the fluid pressure inside the passage 14 to prevent the excessive pressure from damaging the forming mold. Referring to Figures 4 and 5, the high temperature fluid source 2 is used to provide a high temperature fluid, for example, by applying sharp water to generate a high pressure, high temperature, m warm fluid source 2Q through a heating line 21 and a plurality of heating diverter valves. 22 connects the passage 14 of the forming mold 10 to heat the forming mold 10. Wherein, the heating pipe 21 is connected to the high-temperature fluid source 2, the heating diverter valve 22 is connected to the high-temperature gas source 2 through the heating pipe 21, and the other end is connected to the inlet end 141' of each channel 14 to pass the high-temperature fluid. The heated diverter valve 22 enters each of the passages 14, respectively. Each of the heated diverter valves 22 can be independently switched to determine if the individual passages 14 are venting a high temperature fluid. The heating pipe 21 is further provided with a heating main valve 2 ιι, a pressure head 212, and a temperature sensor 213. The main valve 211 is heated to control the opening and closing of the heating circuit to determine whether the high temperature fluid is obtained through the south temperature fluid source. The force meter 212 and the degree sensor 213 are respectively used to monitor the temperature and pressure of the body temperature in the south temperature fluid source 2 and the heating line 21. In addition, the outlet end 142 of each channel 14 is respectively connected to the high temperature fluid recovery device 5Q through a high temperature 201012627 fluid recovery_by (4) receiving the flow through the channel i4 and heating it to a high temperature for the high temperature after cooling to be reheated by the high temperature. The fluid source 20 is reheated for use. Further, in order to avoid an abnormal state of the high-temperature gas source, the heating pipe 21 is connected to the cooling fluid recovery device 或是 or the outside through the high-temperature fluid bypass valve 214 to vent the abnormal high pressure of the high-temperature fluid source 20. Referring to "Fig. 4" and "Fig. 5", the inner passage 14 for circulating high temperature fluids respectively heats different partial regions of the forming mold 10 to maintain the temperature at which the temperature is close to or higher than the liquid returning temperature. . After the valve liquid enters the cavity 13 of the forming mold 1 (), the high temperature ugly tool 1G can be rotated, so that the sputum flows sufficiently and rapidly to fill the cavity 13 to avoid voids in the plastic formed part, Cracks caused by defects or inconsistent cure speeds. Each of the heating S-flow valves 22A has an independent opening and closing function, and is controlled by the control main unit, and each of the heating diverter valves 22 can be independently switched to open or face. When the local temperature of the forming die 10 reaches or exceeds the set temperature, the control domain controls the heating of the local part to 22°, so that the higher the temperature is no longer entered into the lying channel 14, the stop of the forming die 10 has reached the set temperature. The local part is heated. At the same time, since the maximum total flow rate of the high temperature fluid provided by the high temperature fluid source 20 is a fixed value, when the high temperature fluid of any of the channels 14 is heated by the diverter valve 22, the blocked high temperature fluid is evenly distributed to other passes. 'Improving the flow rate of the other temperatures and increasing the heating rate of the rest of the forming mold 10, so that the overall temperature of the forming mold 1 can be accelerated to a rate of H degree. In addition, a heating stop 222 is provided between the heating channels 22 and the heating check valve 222 for unidirectional passage of the high temperature fluid, and the high temperature fluid is unidirectionally flowed from the high temperature fluid source 2 to the forming. The mold 1 has a channel 14 that does not flow backwards in 201012627. Heating the check valve 222 prevents the high pressure fluid from entering the high temperature fluid source 23 in the reverse direction, causing an abnormal boosting problem. That is to say, due to the influence of the cavity 13 type, the meat thickness of each part of the forming mold 1 may be inconsistent. Under the premise of uniform heat flux, the rate of temperature rise of each part of the forming mold 1 is also inconsistent, and some areas will be raised to the set temperature earlier. The invention individually switches the warming fluid in the different channels 14, blocks the high temperature fluid from continuing to heat the localized region where the temperature has reached the set temperature, and increases the high temperature fluid flow rate in the region where the temperature has not reached the set temperature, so as to shorten the total heating required. time. 9 Referring to Figure 4 and Figure 6, the cooling fluid source 3 is used to provide a cooling fluid, such as low temperature cooling water. The cooling fluid source 3 is coupled to the passage 14 of the forming die 10 through a cooling line 31 and a plurality of cooling split valves 32. Wherein, the cooling line 31 is connected to the cooling source 3G, the cooling part _% - Weiling but the way f 31 is connected in parallel to the cooling fluid source 30, and the other end is connected to the inlet end 141 of each channel 14 respectively, so that the cooling fluid passes through the cooling point. _ 32 points for the ship's passage 14 to cool down into a 1 (). Each of the cooling split valves 32 is independently switchable to determine if the individual passages 14 are open to the cooling fluid.冷却 The cooling line 31 is further provided with a cooling main _ 3U, a pressure gauge 312, a temperature sensor 313, and a pump 314. The cooling main_311 is used to control the opening and retracting of the cooling line 31 to determine whether the cooling age pressure gauge 312 and the temperature meter head 313 are respectively obtained through the cooling fluid source 3G for monitoring the cooling fluid 塬3〇 and the cooling line 31, respectively. Fluid temperature and pressure. The Lipu 314 is used to generate a pressure difference, and the cooling fluid source is not taken from the cooling fluid source 3, and the cooling fluid body is sent toward each cooling unit. In addition, the outlet ends 142 of the respective channels are connected to the cooling fluid recovery device 6 through the through-cooling fluid recovery valve 61, thereby recovering the flow passage 14 and cooling the cooling frequency of the mold 1G to re-cool the cooling 11 201012627 fluid. The fluid source 30 is re-cooled and cooled for recycling. Further, in order to avoid an abnormal state in the pumping pressure of the pump 314, the cooling line 31 is connected to the cooling fluid recovery device 60 or the outside through a cooling fluid bypass valve 315 to vent the abnormal high pressure caused by the pump 314. Referring to "Fig. 4" and "Fig. 6", the cooling fluids in the passage 14 are respectively cooled to different partial regions of the forming mold 10 to rapidly cool the temperature of the forming mold to the mold opening temperature (usually It is the softening temperature of the plastic, about 8 degrees Celsius. When the cooling fluid enters the passage 14 of the forming mold 10, it can quickly absorb heat and leave the outlet end 142 of the passage to accelerate the solidification of the plastic liquid, avoid waiting for the plastic to solidify and can open the mold. Since each cooling diverter valve 32 has an independent opening and closing function, which is controlled by a control host, each cooling diverter valve 32 can be independently switched to open or close. When the forming mold 10 has a local temperature already After lowering to the mold opening temperature, the control host controls the cooling split valve 32 corresponding to the local part to be closed, so that the cooling fluid no longer enters the corresponding passage 14 to cool the local area, and the cooling button that can be sent by the The maximum total flow is a fixed value, so when the cooling fluid of either channel 14 is blocked by the cooling split valve 32, the blocked cooling fluid is evenly distributed to The passage 14 increases the flow rate of the cooling fluid in the other passages 14 to increase the cooling rate of the remaining portion of the workpiece 1 so that the overall temperature of the forming mold 10 can be accelerated to a rate at which the mold opening temperature is lowered. Further, each cooling split is performed. A cooling check valve 322 is further disposed between the valve 32 and the passage 14 for unidirectionally passing the high-limit cooling fluid unidirectionally from the cooling fluid source 3 to the passage 14 of the forming die 1' The cooling check valve 322 prevents the cooling fluid from being reversely entered into the cooling fluid source 30 by the cooling fluid recovery device 6 due to the siphon phenomenon after the pump 314 is stopped. 12 201012627 That is, due to the cavity type 13 The influence of the thickness of each part of the forming mold 10 may be inconsistent. Under the premise that the local cooling power is uniform, the rate of temperature drop of each part of the forming mold 10 is also inconsistent, and some areas will be cooled to the mold opening temperature earlier. The cooling fluid in the different channels 14 blocks the cooling fluid from continuing to cool the localized area that has cooled down to the mold opening temperature, while the other parts of the force velocity The cooling rate of the domain is shortened to shorten the time required for cooling. The high temperature fluid supplied by the local temperature fluid source is heated before the plastic liquid is injected into the forming mold 10, and then the heating device 10 is heated to a relatively high temperature working temperature. After the plastic mold is injected into the forming mold 10, the high-temperature forming mold 10 prevents the plastic liquid from rapidly cooling and solidifying. At the same time, the plastic liquid maintaining the high temperature has a low viscosity coefficient, and accelerates the flow of the plastic liquid to fill the cavity 13' to ensure that the plastic liquid fills the cavity. 13 to reduce the occurrence of cavitation. The cooling fluid source 3〇 rapidly reduces the temperature of the forming mold 1G and Na (liquid), so that the temperature of the forming mold 1Q and the plastic win is rapidly lowered to the mold opening temperature. The warm fluid enters the passage 14 to be heated. After the process of forming the mold 10, the high temperature fluid remains in the passage 14 _ 'for example, when the high temperature fluid is water vapor, the high temperature fluid source 2 〇 stops supplying money, and the passage 14 will trace the water or the high temperature water droplets' A cooling wire that affects the subsequent cooling fluid to the forming die 10. Similarly, after the cooling fluid enters the passage 14 to cool the forming mold 1〇, the passage will be cooled, and the subsequent two warm fluids will flow, so that the partial area of the forming mold 10 is due to the residual cold body, The method is smoothly heated to a predetermined temperature. Therefore, at the end of the heating or cooling process, '', a draining procedure must be performed' to exclude residual high temperature fluid in the passage 14 or to cool. Referring to "Fig. 4" and "Fig. 7", the liquid discharge device 4 is a pressure difference generating device 'for example, an anesthetic device or a high-pressure gas source, and the peak is sent to the high-pressure and dry air 13 201012627 in a predetermined direction. flow. The draining device 40 is connected to the passage 14 of the forming die 40 through a drain line 41 and a plurality of draining diverters 42. Wherein, the liquid discharge diverter valve 42 is connected in parallel to the liquid discharge device 40 through the drain line 41, and the other end is connected to the inlet end 141' of each channel μ, respectively, so that the high pressure and dry gas enters the channel through the liquid discharge diverter valve 42 respectively. The passage 14 is subjected to a high-pressure high-speed air flow to discharge the condensed liquid or high-temperature steam remaining inside the passage 14. A drain main valve 411, a pressure gauge head 412, a temperature sensor 413, and a solenoid valve group 414 are further disposed on the drain line 41. The drain main valve 411 is used to control the opening and closing of the drain pipe 41 to determine whether or not the high pressure drying gas is supplied through the drain device. The pressure gauge head 412 and the temperature gauge head 413 are used to monitor the temperature and pressure of the fluid in the drain device 4 and the drain line 41, respectively. The solenoid valve block 414 is used to regulate the flow of high pressure gas through the drain line 41. In addition, when the liquid discharge device 40 discharges with a high-pressure drying gas, the high-temperature fluid recovery valve 51 or the cooling fluid recovery valve 61 must be in an open state, so that the passage 14 is in an open passage to push out the remaining cooling fluid or high-temperature fluid. Channel 14. Referring to FIG. 8 , a rapid heating and cooling forming system according to a second embodiment of the present invention includes a forming die 10 , a high temperature fluid source 2 , a cooling flow source 30 , and a row. The liquid device 40, a high temperature fluid recovery device 50, and a cooling fluid recovery device 60. The forming mold 10 is used for molding a plastic liquid therein and cooling and solidifying, and the forming mold 10 has a plurality of passages 14 passing through the forming mold 10 for supplying a high temperature fluid, a low temperature fluid, or a drying gas to form a pair. The mold 1 is heated or cooled. A high temperature fluid, a cryogenic fluid, or a drying gas enters the passage 14 via the inlet end 141 and passes through the outlet end 142 after passing through the forming die 10. Each of the channels 14 has an opening and closing valve 145, which is disposed at the inlet end 141, and each of the opening and closing valves 145 is independently controlled by a control unit, and is turned on or Μ ' so that each channel μ is touched up and turned on. Or close the β-close valve 145 through-heating pipeline in parallel with the high-temperature miscellaneous source 2 (), so that the high-temperature fluid passes through the different 145 points to separate the different channels of the 14 towel, which is divided into different local areas of the lion. . The opening and closing valve 145 is simultaneously connected to the cooling fluid source 3 through the through-cooling line 31, so that the cooling fluid 30 enters the different passages 14 through the respective opening and closing valves 145, and is cooled to different partial regions of the display 10, respectively. At the same time, the opening and closing valve U5 is simultaneously connected to the liquid discharging device 4 through a drain line 41, and the high-pressure drying gas is respectively introduced into the different passages 14 through the respective opening and closing valves 145, and the residual fluid in the passage 14. 'In this second implementation shot' each channel u has an independent switch (4), which is controlled by a host (4). Each channel 14 is independently switched to open _ for its corresponding opening 145. Reduce or cool the rags, if the job (4) local temperature rises or cools to a predetermined temperature, the control panel controls the specific opening and closing valve 145 to close the thief 14 (four) thief 14 . Cai 14 » After the ride, the high thief cooling fluid is no longer heated or cooled by the corresponding (four) road 14 and the average frequency (four) cap contact area. The blocked high temperature fluid or cooling fluid is evenly distributed to the other passages 14' to increase the flow rate of the high temperature fluid or cooling fluid in the other passages 14 to accelerate the temperature change rate of the rest of the forming mold 10, shortening the heating or cooling required Time while reducing the energy required to heat or cool.
