Description

Technical Field

[0001] This invention belongs to the field of injection molding equipment technology, specifically a multi-cavity automotive camera lens barrel injection molding device. Background Technology

[0002] Multi-cavity automotive camera lens barrel injection molding refers to a device that uses multiple independent cavity structures on a mold to simultaneously injection mold multiple automotive camera lens barrels during the injection molding process. Its core lies in using multi-cavity molds to achieve efficient mass production, meeting the large-scale demand for lens barrel components in the automotive camera industry, while ensuring that the lens barrels produced by each cavity are consistent in terms of dimensional accuracy and optical performance, thereby improving production efficiency and product quality stability.

[0003] In multi-cavity batch injection molding, the mold has a large overall volume and a large injection volume per cycle. Therefore, a corresponding cooling system is needed to quickly remove the large amount of heat generated during injection molding and ensure temperature uniformity in all cavity areas of the mold. In actual production, a large amount of heat transferred by the cooling system is a type of recoverable energy. Therefore, in order to comply with the production concept of energy conservation and emission reduction and reduce product production costs, conventional technologies usually add a waste heat recovery module to the cooling circuit to exchange and collect the heat carried by the circulating coolant.

[0004] For example, a circulating cooling water waste heat recovery and utilization system disclosed in the related technology, application number CN2024101955297, improves the utilization effect of injection molding waste heat by recovering heat from the cooling water of the injection molding equipment and using the heat to heat the injection molding raw materials. However, in actual application, it was found that, on the one hand, because the temperature of the cooling water is relatively uniform before entering the injection molding equipment, the cooling rate of the cooling water on the front and back of the injection molding equipment is different as the temperature difference between the cooling water and the injection molding equipment decreases. On the other hand, because the total amount of cooling water is large during the cooling process of the injection molding equipment, and the temperature difference between the front and back sections of the cooling water is high, the overall temperature drops after the cooling water is mixed. This temperature drop makes the recovery and utilization of cooling water heat more difficult.

[0005] In view of this, the present invention proposes a multi-cavity vehicle camera lens barrel injection molding device to solve the above-mentioned technical problems. Summary of the Invention

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 8 As shown, the multi-cavity vehicle camera lens barrel injection molding device of the present invention includes an injection mold 1, a cooling water tank 2 and a heat exchanger 11 connected in sequence. It also includes a segmented temperature control mechanism, which is installed in the cooling water tank 2. The segmented temperature control mechanism divides the cooling water according to the temperature to enhance the cooling effect on the injection mold 1 and the heat exchange effect on the heat exchanger 11. The segmented temperature control mechanism includes a partition plate 21, an inlet pipe 23, an outlet pipe 24, and a water pump 25; A partition plate 21 is fixedly installed in the cooling water tank 2. Both the partition plate 21 and the cooling water tank 2 are made of heat insulation and heat-resistant materials. The partition plate 21 divides the cooling water tank 2 into multiple non-conductive heat-insulating chambers 22. The injection mold 1 is equipped with a water inlet pipe 23 and a water outlet pipe 24. Both the water inlet pipe 23 and the water outlet pipe 24 are insulated pipes. A water pump 25 is fixedly installed at the end of the water inlet pipe 23 away from the injection mold 1. The water pump 25 is slidably installed on the cooling water tank 2. During the cooling process of injection mold 1, the input end of water pump 25 and the outlet pipe 24 are sequentially connected to multiple heat preservation chambers 22.

[0023] During the cooling process of injection mold 1, the temperature of injection mold 1 gradually decreases, which in turn causes the temperature of the discharged cooling water to gradually decrease. Since the injection temperature and cooling water flow rate are fixed values, in the same injection cooling process, the cooling water outflow temperature is related to the cooling water outflow time. According to the cooling water outflow time, the cooling water can be divided into multiple different temperature segments. In order to separate the high-temperature cooling water from the low-temperature cooling water, a segmented temperature control mechanism is provided in this invention to separate the high-temperature cooling water from the low-temperature cooling water, and the low-temperature cooling water is reused for cooling, so that the low-temperature cooling water is gradually transformed into high-temperature cooling water for heat exchange treatment.

[0024] Specifically, during the injection molding process, when the injection mold 1 is in the cooling process, the water pump 25 is started by a pre-set program. The water pump 25 draws cooling water from its initial position and pumps it into the injection mold 1 through the inlet pipe 23. Finally, it is discharged back into the insulation chamber 22 through the outlet pipe 24. During the gradual circulation process, the temperature of the cooling water in the current insulation chamber 22 gradually increases. After the set time is reached, the water pump 25 input end and the water pipe extend to the next insulation chamber 22 according to the arrangement of the insulation chambers 22. Through the circulation of the cooling water in the next insulation chamber 22, its temperature gradually increases. Because the injection mold 1 is cooling... During the process, the temperature continues to decrease. Therefore, as the water pump 25 input end and the water outlet pipe 24 are sequentially connected to multiple heat-insulating chambers 22, the injection mold 1 is cooled. The cooling water in the multiple heat-insulating chambers 22 gradually decreases in temperature according to the connection sequence, and the heat exchanger 11 exchanges heat with the high-temperature cooling water in the first heat-insulating chamber 22. In the next injection process, the initial position of the water pump 25 is changed, and the water pump 25 is moved from the second heat-insulating chamber 22. Finally, in multiple injection processes, the high-temperature cooling water that has reached the threshold is always exchanged for heat, while the cooling water that has not reached the threshold is gradually increased in temperature in multiple cycles to achieve continuous heat exchange.

[0025] This invention stores cooling water in segments and changes the initial position of the water pump 25 during multiple injection molding processes. This allows the cooling water in multiple insulation chambers 22 to sequentially reach a set threshold state. The cooling water that reaches the threshold state then undergoes heat exchange treatment. On one hand, this ensures that the temperature of the cooling water used for heat exchange reaches the set temperature, making the heat exchange process more convenient. On the other hand, the temperature of the cooling water in multiple insulation chambers 22 increases gradually, eventually reaching the set temperature sequentially. This ensures a continuous supply of cooling water ready for heat exchange, facilitating the continuous heat exchange operation. Furthermore, after the first cooling operation, the temperature of the cooling water delivered to the injection mold 1 gradually decreases during a complete cooling process. This matches the gradual cooling characteristic of the injection mold 1 during its cooling process, reducing the temperature difference between the cooling water and the injection mold 1. Consequently, the cooling efficiency of the injection mold 1 remains relatively stable, thus reducing the impact of large fluctuations in cooling efficiency on the quality of the injection molded product.

[0026] In a preferred embodiment of the present invention, a sliding track 3 is fixedly installed on the cooling water tank 2. The extension direction of the sliding track 3 is the same as the arrangement direction of the plurality of heat preservation chambers 22. A sliding seat 31 is slidably installed on the sliding track 3. The water pump 25 is fixedly installed on the sliding seat 31. A traveling wheel 33 is rotatably installed on the sliding seat 31 by an electric motor 32.

[0027] The cooling water tank 2 is a partially annular design, while the sliding track 3 is a fully annular design. The input end of the water pump 25 and the end of the water outlet pipe 24 away from the injection mold 1 are both fixed on the sliding seat 31. The distance between the input end of the water pump 25 and the end of the water outlet pipe 24 is the same as the distance between the two adjacent partition plates 21. The insulation chambers 22 located at the beginning and end are connected to the heat exchanger 11 through the drain pipe 26 and the water supply pipe 27, respectively. The drain pipe 26 is used to transport the hot water in the insulation chamber 22 connected to it to the heat exchanger 11 in real time. After the heat exchanger 11 cools down, it is discharged into the corresponding insulation chamber 22 through the water supply pipe 27. It should be noted that the heat exchanger 11 is equipped with a hot and cold water pumping device to cooperate with the drain pipe 26, the water supply pipe 27 and the cold water pipe to drive the flow of hot and cold water. To further enhance the control effect on cooling water temperature, the cooling water tank 2 in this invention has a partially annular design, while the sliding track 3 has a fully annular design. Initially, the sliding seat 31 is located between the first and second insulation chambers 22. At this time, the input end of the water pump 25 extends into the second insulation chamber 22, and the outlet pipe 24 extends into the first insulation chamber 22. When the water pump 25 starts, the cooling water in the second insulation chamber 22 is pumped to the injection mold 1, where it exchanges heat with the mold. Then, it is discharged through the outlet pipe 24 into the first insulation chamber 22, and finally discharged into the heat exchanger 11 through the drain pipe 26. After heat exchange, it is transported by the water supply pipe 27 to the outermost insulation chamber 22. Simultaneously, the electric motor 32 drives the walking wheels 33. The pump rotates and moves under the guidance of the sliding track 3. It is important to know that the time it takes for the water pump 25 to move from the second insulation chamber 22 to the third insulation chamber 22 coincides with the segmented cooling water flow. Therefore, when the injection mold 1 cools down to below the threshold, the water pump 25 draws cooling water from the third insulation chamber 22 and finally discharges it into the second insulation chamber 22 through the outlet pipe 24. This is so that in the next injection cooling process, the remaining highest temperature cooling water can be delivered to the injection mold 1 first. As the sliding seat 31 continues to operate, when the water pump 25 passes the last insulation chamber 22, a cooling process is completed. At this time, the electric motor 32 still drives the traveling wheel 33 to operate until the sliding seat 31 moves to the initial position for the next injection cooling.

[0028] In this invention, the arrangement of the cooling water tank 2 and the sliding track 3 makes it more convenient to sequentially connect the water pump 25, the water outlet pipe 24 and the multiple heat-insulating chambers 22. Furthermore, with the position settings of the water pump 25 input end and the water outlet pipe 24, the cooling water can flow sequentially in the multiple heat-insulating chambers 22 during the cooling process, and finally the cooling water that meets the temperature is discharged into the heat exchanger 11 for heat exchange treatment.

[0029] In a preferred embodiment of the present invention, a connecting hose 4 is fixedly installed on the cooling water tank 2. The connecting hoses 4 are arranged in pairs, and the number of the connecting hoses 4 corresponds to the number of the insulation chambers 22. A connecting plate 41 is fixedly installed on the end of the connecting hose 4 away from the cooling water tank 2. A magnetic plate 42 is embedded in the sliding seat 31. The magnetic plate 42 is sleeved on the input end of the water pump 25 and the end of the water outlet pipe 24. The magnetic plate 42 and the connecting plate 41 are magnetically attracted to each other.

[0030] The sliding track 3 is provided with a sliding groove 43, which corresponds one-to-one with the docking plate 41. The docking plate 41 is slidably installed in the sliding groove 43. A reset band 44 is fixedly installed in the sliding groove 43. When the docking plate 41 moves with the sliding seat 31, the reset band 44 is gradually stretched.

[0031] To insulate cooling water that does not meet the temperature threshold during multiple injection molding cooling operations, and to reduce the efficiency of heat loss during cooling water flow, the connecting hose 4 in this invention is made of insulating material. When the sliding seat 31 drives the water pump 25, as the sliding seat 31 moves, the magnetic suction plate 42 on the sliding seat 31 aligns with the connecting plate 41 vertically. Under magnetic attraction, the magnetic suction plate 42 and the connecting plate 41 are attracted. At this time, the input end of the water pump 25 and the end of the outlet pipe 24 are respectively connected to the corresponding connecting hose 4. During the continuous movement of the sliding seat 31, the end of the connecting hose 4 away from the cooling water tank 2 moves synchronously with the sliding seat 31 until the connecting plate 41 moves to the end of the sliding groove 43. At this time, under the limiting effect of the sliding groove 43 on the connecting plate 41, the magnetic suction plate... 42 gradually separates from the docking plate 41, and under the continuous movement of the sliding seat 31, quickly docks with the docking plate 41 in the next sliding groove 43. The docking plate 41, which is separated from the magnetic suction plate 42, is quickly reset under the action of the reset band 44 made of elastic material, so as to facilitate the next connection. Under this setting, the opening area of ​​the heat preservation chamber 22 is greatly reduced, thereby reducing the heat dissipation efficiency of the cooling water in the heat preservation chamber 22. At the same time, it should be noted that a rubber sheet with an elastic material and a central opening is also installed at the opening end of the docking hose 4. In the initial state, under the elastic action of the rubber sheet itself, its opening is small and almost closed. However, when the water pump 25 applies negative pressure or the water pressure of the outlet pipe 24 acts on the rubber sheet, the rubber sheet deforms and the opening expands, further reducing the efficiency of heat dissipation through the opening of the docking hose 4.

[0032] In a preferred embodiment of the present invention, a filter float 5 is fixedly installed at the bottom end of the connecting hose 4 corresponding to the input end of the water pump 25, and the connecting hose 4 corresponding to the end of the water outlet pipe 24 extends to the bottom of the heat preservation chamber 22.

[0033] The filter float 5 is an inverted cone-shaped structure with a hollow bottom. The filter float 5 is hollow, and the connecting hose 4 extends into the interior of the filter float 5.

[0034] The filter float 5 is designed to filter the cooling water when the insulation chamber 22 is drawn, thereby reducing the efficiency of scale transfer into the injection mold 1.

[0035] In a preferred embodiment of the present invention, a drainage hood 6 is installed inside the heat preservation chamber 22. The drainage hood 6 is matched with the heat preservation chamber 22. Both the upper and lower ends of the drainage hood 6 are provided with through holes 61. The outer wall of the drainage hood 6 and the inner wall of the heat preservation chamber 22 form a drainage channel 62. The connecting hose 4 corresponding to the end of the water outlet pipe 24 extends to the bottom of the drainage hood 6 through the through holes 61.

[0036] The diameter of the through hole 61 at the top is larger than the diameter of the connecting hose 4, and the diameter of the through hole 61 at the bottom is the same as the diameter of the connecting hose 4. A support plate 63 is fixedly installed at the bottom of the drainage cover 6, and multiple support plates 63 are evenly arranged with the through hole 61 as the center.

[0037] A jet pipe 64 is rotatably installed at the bottom end of the connecting hose 4 corresponding to the end of the water outlet pipe 24. The jet pipe 64 has an arc-shaped design, and the support plate 63 is located on the jet path of the jet pipe 64.

[0038] To further enhance the insulation effect of the multiple insulation chambers 22 and reduce heat dissipation efficiency, in this invention, when the water outlet pipe 24 delivers water to the connecting hose 4 and discharges it to the bottom of the insulation chamber 22, after the water is sprayed out through the spray pipe 64, it flows through the drainage channel 62 formed by the outer wall of the drainage cover 6 and the inner wall of the insulation chamber 22, and flows into the interior of the drainage cover 6 through the through hole 61 at the top of the drainage cover 6. During this process, the scale carried in the cooling water gradually condenses on the outer wall of the drainage cover 6 and the inner wall of the insulation chamber 22. Since the water flows from bottom to top in the drainage channel 62, the probability of scale residue remaining on the inner wall of the insulation chamber 22 is increased, thereby forming a uniform scale layer on the outer wall of the drainage cover 6 and the inner wall of the insulation chamber 22. Since the scale layer has a high resistance effect on temperature conduction, it further reduces the heat dissipation efficiency of the cooling water inside the drain cover 6. At the same time, after the cooling water is sprayed out by the spray pipe 64, it impacts the support plate 63. Under the action of the reaction force, the spray pipe 64 rotates around the docking hose 4. When the height of the cooling water flow is greater than the height of the drain cover 6, under the action of water buoyancy, the support plate 63 drives the drain cover 6 to shake in the heat preservation chamber 22 under the guidance of the impact force. The slight impact generated by the shaking makes the scale layer more uniform, thereby effectively reducing the probability of scale clogging the drain channel 62. It should be noted that the cooling water tank 2 should be cleaned at regular intervals. The specific cleaning method can be acid soaking, etc., to avoid the phenomenon of excessive scale layer.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
