Description

Technical Field

[0001] The invention belongs to the technical field of die casting cooling, and in particular relates to an integrated double-injection molding cooling system. Background Art

[0002] Die casting is an important metal forming method, which is generally carried out through die casting molds. During the die casting process, under the influence of molten metal, the mold will generate a lot of heat. If the heat cannot be discharged in time, the use of the mold will be affected. Indirectly affecting the quality of die-cast products will also waste resources. Most existing die-casting molds are naturally cooled, and the cooling time is very long, which reduces the production efficiency of castings. In addition, when the condensate circulates in the cooling channel of the mold for a long time, it is easy to scale in the cooling channel, block the cooling channel, and affect the use of the cooling system.

[0003] To this end, Chinese patent CN112059146A discloses a die-casting mold cooling device, including a heat exchange mold base, a bottom mold and a cooling cylinder. A heat exchange cavity is provided inside the heat exchange mold base, and a bottom mold is provided in the heat exchange cavity. The upper end of the heat exchange mold base is fixedly connected to the mold cover by bolts, and the lower surface of the mold cover is pressed against the upper end of the bottom mold. Beneficial effect: the present invention places the bottom mold in the heat exchange cavity opened by the heat exchange mold base, and the gap formed between the bottom mold and the inner cavity of the heat exchange cavity is used to flow condensate, so as to exchange heat and cool the bottom mold. The mold cover fixedly connected to the upper end of the heat exchange mold base by bolts presses the bottom mold tightly. Its structure is convenient for installation and disassembly, and it is convenient to clean the inner wall of the heat exchange cavity and the outer wall of the bottom mold to prevent scaling and clogging. When the condensate evaporates and generates excessive pressure during heat exchange with the bottom mold, its pressure will The sealing block is pushed open, so that the condensed liquid flows out along the second liquid discharge interface and the pressure relief cylinder seat to relieve the pressure; however, with the continuous promotion of lightweight automobiles, the size of die-castings produced by the single-sided feeding system corresponding to the single-material cylinder in die-casting has almost reached its upper limit, and it is necessary to introduce a double-shot system, that is, by introducing two metal runners, the molten metal enters the cavity from the two runners at the same time. The runner, as the first part of the mold to accommodate the molten metal, requires additional special heat dissipation, and the above-mentioned cooling system can only cool the entire mold cover on one side of the heat exchange cavity, and fails to make adaptive improvements to the double runner structure in this type of double-shot molding die-casting system, and cool the double runner structure, and the cooling effect is not good.

This reduces the temperature difference between different parts of the die-casting mold body, thereby reducing the probability of local cracking of the die-casting mold body due to uneven thermal expansion and contraction.

[0029] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0030] See also Figure 1-3 , an integrated double-injection molding cooling system, comprising a die-casting mold body 1, wherein the die-casting mold body 1 is provided with a cavity 12 and two runners 11 connected to the cavity 12, and the runners 11 are connected to a barrel containing molten metal;

[0031] Specifically, the die-casting mold body 1 at least includes a barrel, which is connected to a runner 11. Optionally, there are two barrels, which are respectively connected to two runners 11. The barrel is used to hold molten metal raw materials. When in use, the molten metal raw materials in the barrel are pressed into the two runners 11 under the action of an external pressure source. Subsequently, the molten metal enters the cavity 12 along the two runners 11 under the action of the pressure source, and is formed in the cavity 12 to complete the die-casting process. At the same time, by setting the number of runners 11 to two, the speed at which the molten metal raw materials enter the cavity 12 becomes faster, and the molten metal can fill more cavity 12 space before the fluidity decreases, thereby increasing the size of the parts formed by a single die-casting.

[0032] In the above process, due to the high temperature of the molten metal, after entering the runner 11, a large amount of heat will dramatically increase the temperature of the mold. When the mold is at a high temperature for a long time, there is a probability that the mold fatigue process will be accelerated, thereby causing damage to the mold. At the same time, the long-term high temperature of the mold has a probability of causing the mold to change the shape of the cavity 12 under the action of thermal expansion and contraction, thereby affecting the quality of the finished die-casting casting. Therefore, it is necessary to control the temperature of the die-casting mold. For this purpose, the die-casting mold body 1 is provided with two cooling modules 2, and any cooling module 2 includes a coolant pipe 23, a circulating pump 22 and a heat exchanger 21. The coolant pipe 23, the circulating pump 22 and the heat exchanger 21 of any cooling module 2 are arranged in series, and the circulating pump 22 is used to drive the coolant in the coolant pipe 23 to pass through the heat exchanger 21 and the coolant pipe 23 in sequence;

[0033] Specifically, each coolant pipe 23 contains coolant, and the coolant pipe 23 itself forms a loop. The circulation pump 22 and the heat exchanger 21 are both arranged in the loop formed by the coolant pipe 23 itself. The two cooling modules 2 and the two runners 11 are arranged one by one, and one cooling module 2 corresponds to one runner 11.

[0034] At the same time, a portion of the coolant pipe 23 is disposed in the mold body, and the portion of the coolant pipe 23 located in the mold body is disposed on one side of the runner 11. Specifically, the portion of the coolant pipe 23 located on one side of the runner 11 is spiral, and the spiral coolant pipe 23 is wound and disposed on the outside of the runner 11.

[0035] When in use, the coolant in the coolant pipe 23 in each cooling module 2 passes through the coolant pipe 23, the circulating pump 22 and the heat exchanger 21 in sequence under the action of the circulating pump 22. When the molten metal raw material enters the cavity 12 through the runner 11 and releases a large amount of heat to the mold body, the coolant cooled by the heat exchanger 21 continuously enters the part of the coolant pipe 23 located at the mold body under the action of the circulating pump 22. The heat of the die-casting mold body 1 is transferred to the coolant with a lower temperature. Then the coolant flows along the coolant pipe 23 to the heat exchanger 21. The heat exchanger 21 cools down the heated coolant, completing the process of the cooling module 2 bringing the heat in the die-casting mold body 1 to the heat exchanger 21, thereby completing the heat dissipation of the die-casting mold body 1.

[0036] By respectively setting two cooling modules 2 corresponding to the two runners 11, the coolant pipes 23 of the two cooling modules 2 are wound around the outside of the runner 11, and the two runners 11 in the double-injection die-casting mold are cooled respectively, so that the cooling system can cool the double runner 11 structure, thereby improving the cooling effect.

[0037] In the above process, when the cooling module 2 cools the runner 11 of the die-casting mold body 1, when the cooling power is too small and the temperature of the die-casting mold body 1 is too high, the cooling module 2 will not be able to effectively cool the die-casting mold body 1. On the contrary, when the cooling power is greater than the heat dissipation requirement of the die-casting mold body 1, the cooling module 2 will consume extra energy and waste resources, and there is a probability that the local cold and hot gap in the mold will be too large, thereby causing the mold to be damaged under the effect of thermal expansion and contraction. To avoid such a situation, any cooling module 2 includes a temperature sensor, and any temperature sensor is electrically connected to the control module 3. The two temperature sensors are respectively used to detect the temperature of the die-casting mold body 1 located around the two runners 11, and upload the temperature data to the control module 3. When the control module 3 determines that the temperature data exceeds the threshold, the power of the corresponding cooling module 2 is increased, and when the control module 3 determines that the temperature data is lower than the threshold, the power of the corresponding cooling module 2 is reduced;

[0038] Specifically, the control module 3 is electrically connected to two temperature sensors, which are respectively arranged at the parts of the die-casting mold body 1 located around the two runners 11, and respectively detect the temperature around themselves in real time. The two temperature sensors are respectively recorded as No. 1 and No. 2, and the temperatures of the No. 1 temperature sensor and the No. 2 temperature sensor are respectively recorded as temperature data T1 and T2. The two temperature sensors upload the detected temperatures T1 and T2 to the control module 3 at a frequency of once per second. At the same time, the control module 3 is pre-input with a temperature threshold T0 and a reference power p0 of the cooling module 2. Subsequently, after receiving the temperature data every second, the control module 3 determines the powers p1 and p2 of the two cooling modules 2 according to the temperature data. The cooling module 2 operating with power p1 is the cooling module 2 arranged near the No. 1 temperature sensor, and the cooling module 2 operating with power p2 is the cooling module 2 arranged near the No. 2 temperature sensor.

[0039] Among them, p1=T1 / T0×p0, p2=T2 / T0×p0, when T1 is large, it means that the temperature around the first temperature sensor is large, and the cooling module 2 needs to increase the cooling power to increase the cooling efficiency of the runner 11 near the temperature sensor to reduce the temperature of the corresponding runner 11. At this time, the value of T1 / T0 is increased, and the value of p1=T1 / T0×p0 is increased. When the control module 3 instructs the cooling module 2 near the first temperature sensor to operate at power p1, it can be achieved when the temperature of the corresponding runner 11 of the cooling module 2 is high and a larger cooling power is required. Increase the cooling power, similarly, when T1 is small, it means that the temperature around the first temperature sensor is low. At this time, I allow the cooling module 2 to increase the cooling power, and the value of T1 / T0 is reduced. The value of p1=T1 / T0×p0 is reduced. When the control module 3 instructs the cooling module 2 near the first temperature sensor to operate at power p1, it can be achieved when the temperature of the corresponding runner 11 of the cooling module 2 is low and a larger cooling power is not required. Reduce the cooling power;

[0040] The above method can also realize an increase in the cooling power of the cooling module 2 operating at the power p2 when the temperature of the runner 11 is high, and a reduction in the cooling power when the temperature of the runner 11 is low;

[0041] By setting a temperature sensor to detect the temperature near the two runners 11, the control module 3 increases the power of the cooling module 2 corresponding to the runner 11 when the temperature of a runner 11 increases, and reduces the power of the cooling module 2 corresponding to the runner 11 when the temperature of the runner 11 decreases, thereby ensuring the cooling effect when the temperature of the runner 11 is high and additional cooling power is needed, and saving energy consumption when the temperature of the runner 11 is low.

[0042] During the die-casting process, the main heating process of the mold body by the molten metal is the moment when the die-casting just starts, when the molten metal enters the mold cavity 12 along the two runners 11 respectively under the action of the pressure source. At this time, the mold body is subjected to a sharp temperature rise, and the demand for cooling effect is high. Therefore, the cooling module 2 needs to realize rapid cooling of the die-casting mold body 1 at the time when the die-casting starts. For this purpose, the control module 3 is used to obtain the time when the die-casting starts, and the control module 3 increases the power of the cooling module 2 at the time when the die-casting starts;

[0043] Specifically, the control module 3 inputs the time point at which die casting starts, and the control module 3 is used to control the die casting action of the die casting mold body 1. At the same time, the control module 3 is provided with a timer. When the timer shows that the current time matches the time point at which die casting starts, the control module 3 instructs the die casting mold body 1 to start die casting. At the same time, at the time point at which die casting starts, the control module 3 synchronously increases the power of the cooling module 2.

[0044] Specifically, the time point of the die casting start input to the control module 3 is recorded as t0, and the timer in the control module 3 is used to calculate the current time t, where t is the real time in seconds. The control module 3 calculates the correction coefficient A1 according to the time t, and adjusts the power of the two cooling modules 2 to p1×A1 and p2×A1; wherein A1=4^(-|t-t0|+1), t0-1≤t≤t0+1, and c is a pre-input constant. When the control module 3 determines that the current t is less than t0-1, the control module 3 takes t=t0-1 when calculating A1, and when the control module 3 determines that the current t is greater than t0+1, the control module 3 takes t=t0+1 when calculating A1;

[0045] When the counter calculates that there is less than one second left from the current time to the start of die casting, that is, t0-1≤t≤t0, it means that the time point of die casting is approaching. At this time, the molten metal is about to input a large amount of heat to the die casting mold body 1, and the power of the cooling module 2 needs to be increased accordingly to ensure the cooling effect. At this time, the value of |t-t0| approaches 0 from 1, and the value of A1=4^(-|t-t0|+1) approaches 4 from 1. At this time, the values ​​of p1×A1 and p2×A1 increase as t approaches t0. As the time point of die casting approaches, the die casting mold body 1 is ready to withstand a large amount of heat, and the control module 3 corrects the power of the cooling module 2 upward to a greater extent;

[0046] When t=t0, it means die casting starts, and the die casting mold body 1 is subjected to a sharp temperature rise. At this time, the heat of the die casting mold body 1 reaches the maximum. At this time, |t-t0|=0, and the value of A1=4^(-|t-t0|+1) reaches the maximum value 4. At this time, the control module 3 instructs the power of the two cooling modules 2 to be adjusted to p1×A1 and p2×A1, so that the power of the two cooling modules 2 reaches the maximum value, that is, 4 times the normal value. At the time point when die casting starts, when the die casting mold body 1 is subjected to a rapid temperature rise, the power of the cooling module 2 is increased to the maximum accordingly;

[0047] When t0≤t≤t0+1, it means that the die casting has been completed, and the heating rate of the die casting mold body 1 slows down. At this time, a larger cooling module 2 power is not needed. At this time, |t-t0| approaches 1 from 0, and the value of A1=4^(-|t-t0|+1) gradually decreases from 4 to 1. At this time, the control module 3 instructs the power of the two cooling modules 2 to be adjusted to p1×A1 and p2×A1, so that the power of the two cooling modules 2 is gradually reduced, and the cooling power is gradually reduced after the die casting starts.

[0048] By setting a timer, the control module 3 will adjust the power of the two cooling modules 2 to p1×A1 and p2×A1 according to the timer and the start time of die casting according to A1=4^(-|t-t0|+1), thereby completing the upward correction of the power of the cooling module 2 when the required cooling power is large at the start time of die casting.

[0049] In actual use, a single cooling module 2 may not be able to sufficiently dissipate heat for the die-casting mold body 1. The cooling module 2 can only cool the die-casting mold body 1 around the runner 11, and the cooling efficiency of the die-casting mold body 1 as a whole is low. In order to improve the cooling efficiency, an air cooling module is provided on one side of the die-casting mold body 1. The air cooling module is arranged toward the die-casting mold body 1, and the air cooling module is electrically connected to the control module 3, and the control module 3 drives the air cooling module to operate;

[0050] Specifically, the air cooling module includes at least one fan arranged toward the die-casting mold body 1. The fan is electrically connected to the control module 3. The control module 3 controls the start and stop of the air cooling module by whether to supply power to the air cooling module. When auxiliary heat dissipation is needed, the control module 3 itself instructs the air cooling module to start, or the operator instructs the air cooling module to start through the control module 3 to complete the auxiliary heat dissipation of the die-casting mold body 1.

[0051] During the above cooling process, due to the difference in working conditions between the two cooling modules 2, or the difference in speed of the barrels inputting raw materials corresponding to the two runners 11, sometimes the temperature difference between the two runners 11 and the nearby part of the die-casting mold body 1 is large, and there is a temperature difference between the two parts of the die-casting mold body 1 for a long time, which may cause the die-casting mold body 1 to crack locally due to uneven thermal expansion and contraction. To avoid such a situation, the control module 3 is pre-input with a difference threshold c0, and the control module 3 is pre-input with the control module 3 judging whether the value of |T1-T2| exceeds c0. When the judgment result is yes, the control module 3 instructs the cooling module 2 to adjust to p1×A2 and p2×A3, wherein A2=1+(T1-(T1+T2) / 2) / T1, A3=1+(T2-(T1+T2) / 2) / T2;

[0052] When the value of |T1-T2| exceeds c0, and T1 is relatively small relative to T2, it means that the temperature near the No. 1 temperature sensor is too low, and the temperature near the No. 2 temperature sensor is too high. At this time, it is necessary to reduce the power of the cooling module 2 near the No. 1 temperature sensor and increase the power of the cooling module 2 near the No. 2 temperature sensor, thereby reducing the temperature of the part with too high temperature and increasing the temperature of the part with too low temperature; at this time, T1 is less than the mean of the two temperature data (T1+T2) / 2, and the value of T1-(T1+T2) / 2 is a negative number. Since the temperature during the die-casting process is greater than 0, the value of A2=1+(T1-(T1+T2) / 2) / T1 is less than 1. Similarly, the value of A3=1+(T2-(T1+T2) / 2) / T2 is greater than 1. When the control module 3 instructs the cooling module 2 to adjust to p1×A2 and p2×A3, the power of the cooling module 2 near the No. 1 temperature sensor is reduced, and the power of the cooling module 2 near the No. 2 temperature sensor is increased;

[0053] Similarly, when the value of |T1-T2| exceeds c0, and T1 is relatively large relative to T2, it means that the temperature near the No. 1 temperature sensor is too high, and the temperature near the No. 2 temperature sensor is too high. At this time, the value of A2=1+(T1-(T1+T2) / 2) / T1 is greater than 1. Similarly, the value of A3=1+(T2-(T1+T2) / 2) / T2 is less than 1. When the control module 3 instructs the cooling module 2 to adjust to p1×A2 and p2×A3, the power of the cooling module 2 near the No. 1 temperature sensor is increased, and the power of the cooling module 2 near the No. 2 temperature sensor is reduced.

[0054] By making the control module 3 determine whether the temperature difference between the two temperature sensors is greater than the difference threshold, and when the judgment result is yes, increasing the power of the cooling module 2 of the part with too high temperature, and reducing the power of the cooling module 2 of the part with too low temperature, thereby reducing the temperature of the part with too high temperature and increasing the temperature of the part with too low temperature, the temperature difference between different parts in the die-casting mold body 1 is reduced, thereby reducing the probability of local cracking of the die-casting mold body 1 due to uneven thermal expansion and contraction.

[0055] In order to facilitate the input of constants such as p0, c and t0, a control panel is also included. The control panel is electrically connected to the control module 3. The control panel is used to input constants such as p0, c and t0, and is also used to display the values ​​of T1 and T2, and whether the current die casting has started.
