Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically to an injection molding device and method for embedding iron parts. Background Technology

[0002] Injection molding equipment is a key piece of equipment used to process plastic raw materials into plastic products. It works in concert through a series of complex mechanical, hydraulic, and electrical control systems to heat and plasticize plastic granules or powder, then injects it into a mold cavity under high pressure. After cooling and solidification, the plastic product is obtained. With the development of injection molding technology, iron parts are now embedded in the injection molded parts. Injection molding equipment with embedded iron parts typically requires placing the iron part inside the mold, and after injection molding, the plastic material encapsulates the iron part. These types of products are widely used in the manufacturing of automotive parts.

[0003] The embedded iron injection molding device is a combination of existing injection molding equipment and robotic arms. The robotic arm embeds the iron part into the injection mold, and then the injection molding equipment realizes the injection molding of the product. Finally, the robotic arm is used to pick up the molded product.

[0004] In the prior art, a Chinese patent with authorization announcement number CN113290802B discloses an injection molding equipment and method with automatic material feeding, including a machine body, an injection molding mechanism on one side of the top of the machine body, and an injection molding chamber on the other side of the top of the machine body.

[0005] While the technical solution in the aforementioned patent document achieves self-feeding of the molded product, it still has the following drawbacks during use: Although direct contact between the molded product and the liquid in the receiving tank below after demolding can achieve rapid cooling of the product, it may cause thermal stress inside the product, leading to deformation or cracking and affecting the product's pass rate; Some impurities will adhere to the molded product, and some of these impurities will scatter into the liquid when it comes into contact with the liquid for cooling. When discharging the molded product, the filter screen can only separate the molded product from the liquid and cannot filter out the impurities mixed in the liquid. As a result, the impurity content in the liquid will continue to increase during the subsequent unloading of the molded product, thus posing a risk of contaminating subsequent products. Summary of the Invention

[0006] To overcome the aforementioned deficiencies of the prior art, this invention provides an injection molding apparatus and method for embedded iron parts. By configuring a semiconductor cooling chip body in the cooling mechanism, the temperature of the coolant in the cooling tank is controlled, reducing the temperature difference when it comes into contact with the molded product that has just been demolded. This reduces the probability of damage caused by thermal stress generated inside the product, improving the product cooling efficiency while ensuring its pass rate. Furthermore, with the cooperation of the cleaning component and the blowing mechanism, an aeration effect is created inside the cooling tank, which not only cleans the product but also causes impurities in the liquid to float to the surface. The cleaning component then adsorbs and removes the impurities from the liquid surface, ensuring liquid quality and preventing contamination of subsequent products, thus solving the problems mentioned in the background art.

[0023] The second technical solution: A method for using an injection molding device for embedded iron parts, the method comprising the following steps:

[0024] Step 1: Preparation. Start the blower mechanism through the controller to achieve the blowing effect. At this time, the sealing component in the cooling mechanism aerates the liquid in the cooling tank. The blower pipe and the air guide component in the unloading mechanism are both in the air outlet state. Start the semiconductor refrigeration chip in the cooling mechanism. Then, according to the temperature sensor, adjust the temperature of the liquid in the cooling tank to an appropriate state. Then, start the conveying component in the unloading mechanism. Under the transmission action of the transmission component, the airflow discharged by the air guide component in the unloading mechanism will continuously oscillate back and forth.

[0025] Step 2: Embedded part injection molding. The controller body controls the robotic arm body to embed the iron part into the cavity of the moving mold in the injection mold. Then, the controller body starts the hydraulic cylinder in the injection mold to close the moving mold and the fixed mold. Finally, the controller body starts the injection unit to perform injection molding into the injection mold.

[0026] Step 3: Demolding and unloading. After injection molding is completed, the program in the controller controls the hydraulic cylinder in the injection mold to open the moving mold. When the moving mold in the injection mold opens to its maximum distance, the electric push rods in the injection mold are started simultaneously, causing the moving mold in the injection mold to move further to the left. When the hydraulic cylinder in the injection mold moves further to the left, the molded product in its cavity comes into contact with the corresponding push parts in the injection mold. With the help of the push parts, the molded product is pushed out of the corresponding cavity. The molded product that leaves the cavity falls directly into the cooling mechanism under the action of gravity. Then, the robotic arm re-embeds the new iron part into the cavity of the moving mold in the injection mold.

[0027] Step 4: Cooling and Impurity Removal. The controller activates the multi-section electric push rod of the cleaning component in the cooling mechanism, causing the U-shaped cover in the cooling mechanism to move to the left along with the adsorption plate. During the movement, the U-shaped cover, in conjunction with the guide groove structure on the inner wall of the cooling box and the telescopic plate in the cooling mechanism, lowers the adsorption plate when it reaches its maximum leftward distance. This allows the adsorption plate to contact the liquid surface in the cooling mechanism, adsorbing impurities floating on the surface. At this time, as the U-shaped cover moves, the splicing parts in the cooling mechanism drive the blower pipe to slide laterally. During the movement, the blower pipe blows and cleans the mold cavity of the fixed mold in the injection mold. Then, the controller drives the robotic arm to leave and drives the hydraulic cylinder in the injection mold to close the mold. The injection unit is then activated to inject the new product. The liquid in the cooling box of the cooling mechanism gradually cools down under the action of the semiconductor cooling chip, thus achieving gradual cooling of the molded product entering the cooling box of the cooling mechanism.

[0028] Step 5: Product unloading. The controller starts the rotary motor in the cooling mechanism, causing the sealing parts in the cooling mechanism to flip counterclockwise and open. When the sealing parts in the cooling mechanism open, the liquid and molded products in the cooling tank fall onto the mesh plate in the unloading mechanism under the action of gravity. At this time, the liquid passes directly through the mesh plate in the unloading mechanism, while the molded products slide onto the conveying components in the unloading mechanism. The operation of the conveying components in the unloading mechanism drives the movement of the molded products. The movement of the conveying components in the unloading mechanism drives the air guide components in the unloading mechanism to blow and dry the conveyed molded products through the transmission components in the unloading mechanism. Then, the molded products fall onto the unloading plate in the unloading mechanism by the conveying components in the unloading mechanism. Finally, the molded products on the unloading plate in the unloading mechanism slide down into the external collection basket.

[0029] Step Six: Structural Reset. The controller starts the rotary motor in the cooling mechanism to rotate and reset the sealing component in the cooling mechanism. Then, the circulation mechanism is started to pump the liquid from the unloading mechanism to the cooling mechanism to prepare for the subsequent processing of the molded products. This process is repeated continuously.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] By configuring a semiconductor cooling chip in the cooling mechanism, the temperature of the coolant in the cooling box can be controlled, reducing the temperature difference when it comes into contact with the molded product that has just been demolded. This reduces the probability of damage caused by thermal stress generated inside the product, improving the product's cooling efficiency while ensuring its pass rate.

[0032] By setting up a blower mechanism, the sealing components in the cooling box continuously generate bubbles, creating an aeration effect. This not only cleans impurities from the molded products in the cooling box but also allows impurities mixed in with the liquid to float to the surface. Then, in conjunction with the cleaning components in the cooling mechanism, the impurities on the liquid surface are adsorbed and removed, ensuring liquid quality and preventing contamination of subsequent products.

[0033] The splicing component in the cooling mechanism is connected to the blower mechanism via a hose, enabling the blower pipe to blow out airflow. When the injection mold in the equipment opens, during the displacement of the cleaning component, the splicing component moves with the cleaning component, causing the blower pipe to move linearly. This cleans the inner cavity of the fixed mold in the mold body, reducing impurities inside and further ensuring the production qualification rate of the product.

[0034] By configuring a discharge mechanism below the cooling mechanism, the product and liquid are separated when the molded product is discharged after cooling. The product also needs to be blown by the air guide component during the discharge process, which speeds up the drying efficiency of the product and makes it easier for staff to handle it.

[0075] When the U-shaped cover 67 moves, the cylindrical bottom end of the plug 6113 in the splicing component 611 slides between itself and the inclined groove, causing the splicing component 611 to move linearly. When the U-shaped cover 67 moves downward, the plug 6113 in the splicing component 611 moves downward synchronously under the action of the return spring, ensuring that the bottom end of the cylinder is in the inclined groove. After the plug 6113 moves downward, its conical plug contacts the fixing ring 6112, sealing the inside of the splicing pipe 6111 and preventing airflow from entering the blower pipe 10. When the U-shaped cover 67 moves upward, the plug 6113 moves upward synchronously, stretching the return spring. At this time, the conical plug in the plug 6113 disengages from the fixing ring 6112, allowing gas to enter the blower pipe 10 through the splicing pipe 6111.

[0076] The top end of the splicing pipe 6111 is connected to the blower pipe 10 by bolts, and the splicing pipe 6111 is connected to the blower mechanism 8;

[0077] The blower mechanism 8 consists of an air pump body and an air delivery pipe. The air pump body is mounted on the frame 1, and the air delivery pipe is installed at the output end of the air pump body. The splicing pipe 6111 is connected to the air delivery pipe via a flexible hose.

[0078] The sealing component 62 includes a shaft and a sealing plate. There are two sealing plates, which are symmetrically arranged on both sides of the shaft. The two ends of the shaft pass through the corresponding side wall of the cooling box 61. The shaft has an air guide hole inside, and the sealing plate has a cavity inside. The cavity and the air guide hole are interconnected. The top of the cavity and the air guide hole are provided with multiple nozzles for gas passage. The front end of the shaft is connected to the rotary motor 63, and the rotary connector 612 is arranged at the rear end of the shaft. The rotary connector 612 is also connected to the blower mechanism 8.

[0079] When the blower mechanism 8 is running, some gas enters the air guide hole through the rotating connector 612 and is then discharged through each nozzle, thereby aerating the liquid in the cooling box 61. This not only accelerates the cooling speed and overall cooling of the molded product in the cooling box 61, but also carries the fine impurities attached to it to the liquid surface with bubbles, achieving preliminary cleaning of the molded product.

[0080] Please see Figures 2-4 and Figures 9-12 In this embodiment of the invention, the unloading mechanism 7 includes an unloading box 71 located on the bottom plate. The unloading box 71 is provided with a mesh plate 72, a conveying component 73 and an unloading plate 74 arranged sequentially from left to right inside. The mesh plate 72 and the conveying component 73 are provided with an air guide component 76 above them. The air guide component 76 and the conveying component 73 are linked by a transmission component 75.

[0081] The perforated plate 72 is tilted in the unloading box 71 with the left side higher than the right side. This facilitates the separation of liquid falling on it and makes it easier for the molded products falling on it to slide to the right.

[0082] The conveying assembly 73 includes a motor, a drive roller, and a conveyor belt. There are two drive rollers, both located inside the unloading box 71, and the two ends of the drive rollers pass through the corresponding side walls of the unloading box 71. The two drive rollers are connected by the conveyor belt. The motor is fixedly connected to the rear outer wall of the unloading box 71 by bolts, and the motor is connected to the rear end of the right drive roller.

[0083] The conveyor belt is also equipped with holes for liquid separation, so that the liquid adhering to the molded product can be separated from the molded product during transportation.

[0084] The transmission assembly 75 includes a coupling 751, a reciprocating screw 752, and a bent rod 753. The coupling 751 is installed at the front end of the right transmission roller, the reciprocating screw 752 is disposed on the coupling 751, and an inner ring is threadedly connected to the reciprocating screw 752. The right end of the bent rod 753 is fixedly connected to the outer ring shell wall of the inner ring.

[0085] When the conveying assembly 73 is running, the reciprocating screw 752 is rotated through the coupling 751, and the threaded inner ring on the reciprocating screw 752 moves accordingly when it rotates.

[0086] The air guide assembly 76 is bolted to the top shell wall of the unloading box 71. Multiple notches are linearly opened on the bottom shell wall of the unloading box 71. A round rod 762 is provided in each notch. An air guide plate 763 is movably connected to the round rod 762. A straight plate 764 is movably connected to the top of the air guide plate 763. An adjusting rod 765 is installed on the top of the multiple straight plates 764. The two ends of the adjusting rod 765 pass through the corresponding side wall of the air collection box 761 and are equipped with end plates.

[0087] The left end of the bent rod 753 is fixedly connected to the corresponding end plate by bolts. An air inlet pipe is provided on the top shell wall of the air collection box 761. The air inlet pipe is also connected to the blower mechanism 8 by a hose.

[0088] After the bent rod 753 is connected to the adjusting rod 765 in the air guide assembly 76, when the reciprocating screw 752 rotates, it drives the bent rod 753 to perform reciprocating linear motion through the inner threaded ring, thereby making the adjusting rod 765 move synchronously. The movement of the adjusting rod 765 causes the corresponding air guide plate 763 to swing through each straight plate 764.

[0089] Please see Figures 1-4 In this embodiment of the invention, the circulation mechanism 9 includes a water pump body, an inlet pipe and an outlet pipe. The water pump body is mounted on a base plate, the inlet pipe is used to connect the water pump body and the unloading mechanism 7, and the outlet pipe is used to connect the water pump body and the cooling mechanism 6.

[0090] The liquid in the unloading mechanism 7 can be pumped to the cooling mechanism 6 through the water pump body.

[0091] The present invention discloses a method for using an injection molding device for embedded iron parts, the method comprising the following steps:

[0092] Step 1: Preparation. The blower mechanism 8 is started by the controller body 11 to achieve the blowing effect. Part of the airflow generated by the blower mechanism 8 enters the sealing part 62. At this time, the sealing part 62 in the cooling mechanism 6 realizes the aeration treatment of the liquid in the cooling box 61.

[0093] The air guide components 76 in the blower pipe 10 and the unloading mechanism 7 are also in the air outlet state. The main body 65 of the semiconductor refrigeration chip in the cooling mechanism 6 is activated, and the temperature of the liquid in the cooling box 61 is adjusted to an appropriate state according to the temperature sensor body.

[0094] Then restart the conveying component 73 in the unloading mechanism 7. Under the transmission action of the transmission component 75, the airflow discharged by the air guide component 76 in the unloading mechanism 7 will continuously reciprocate.

[0095] Step 2: Embedded part injection molding. The controller body 11 controls the robotic arm body 5 to embed the iron part into the cavity of the moving mold 45 in the injection mold 4. Then, the robotic arm body 5 resets and picks up the iron part required for the next operation. Next, the controller body 11 starts the hydraulic cylinder 41 in the injection mold 4 to close the moving mold 45 and the fixed mold 47 in the injection mold 4. Finally, the controller body 11 starts the injection unit 2 to inject the product into the injection mold 4, thereby realizing the injection molding of the product.

[0096] Step 3: Demolding and unloading. After injection molding is completed, the program in the controller body 11 controls the hydraulic cylinder 41 in the injection mold 4 to open the moving mold 45 in the injection mold 4. When the moving mold 45 in the injection mold 4 opens to the maximum mileage, the electric push rods 44 in the injection mold 4 are started simultaneously, which drives the moving mold 45 in the injection mold 4 to move further to the left. When the hydraulic cylinder 41 in the injection mold 4 moves further to the left, the molded product in its cavity contacts the corresponding pusher 46 in the injection mold 4. With the help of the pusher 46, the molded product is pushed out of the corresponding cavity. The molded product leaving the cavity falls directly into the cooling mechanism 6 under the action of gravity. The electric push rods 44 will automatically reset after running to the maximum mileage to demold the molded product.

[0097] Then, the main body 5 of the robotic arm re-embeds the new iron part into the cavity of the moving mold 45 in the injection mold 4;

[0098] Step 4: Cooling and impurity removal. The controller body 11 activates the multi-section electric push rod 69 of the cleaning component in the cooling mechanism 6, causing the U-shaped cover 67 in the cooling mechanism 6 to move to the left along with the adsorption plate 610 in the cooling mechanism 6. During the movement, the U-shaped cover 67 in the cooling mechanism 6, in conjunction with the guide groove structure on the inner wall of the cooling tank 61 in the cooling mechanism 6 and the telescopic plate 68 in the cooling mechanism 6, causes the adsorption plate 610 in the cooling mechanism 6 to descend when it reaches the maximum leftward distance. Then, the adsorption plate 610 in the cooling mechanism 6 comes into contact with the liquid surface in the cooling mechanism 6, adsorbing the impurities floating on the liquid surface.

[0099] At this time, as the U-shaped cover 67 in the cooling mechanism 6 moves, the splicing part 611 in the cooling mechanism 6 drives the blower pipe 10 to slide laterally. During the movement, the blower pipe 10 blows and cleans the mold cavity of the fixed mold 47 in the injection mold 4.

[0100] At this time, the controller body 11 drives the robotic arm body 5 to leave and drives the hydraulic cylinder 41 in the injection mold 4, so that the injection mold 4 closes, and then the injection unit 2 is started to realize the injection molding of the new product.

[0101] The liquid in the cooling box 61 of the cooling mechanism 6 gradually cools down under the action of the semiconductor cooling chip body 65 in the cooling mechanism 6, thereby realizing the gradual cooling treatment of the molded product entering the cooling box 61 of the cooling mechanism 6.

[0102] Step 5: Product unloading. The rotary motor 63 in the cooling mechanism 6 is started by the controller body 11, which causes the sealing part 62 in the cooling mechanism 6 to flip and open counterclockwise. When the sealing part 62 in the cooling mechanism 6 is opened, the liquid in the cooling box 61 in the cooling mechanism 6 and the molded product fall onto the mesh plate 72 in the unloading mechanism 7 under the action of gravity.

[0103] At this time, the liquid passes directly through the mesh plate 72 in the unloading mechanism 7 and enters the unloading box 71 for storage, while the molded product slides onto the conveying component 73 in the unloading mechanism 7.

[0104] The operation of the conveying component 73 in the unloading mechanism 7 drives the movement of the molded product. During the operation, the conveying component 73 in the unloading mechanism 7 synchronously drives the air guide component 76 in the unloading mechanism 7 through the transmission component 75 in the unloading mechanism 7 to blow and dry the conveyed molded product.

[0105] Then, the molded product falls onto the unloading plate 74 in the unloading mechanism 7 via the conveying component 73. Finally, the molded product on the unloading plate 74 in the unloading mechanism 7 slides down into the external collection basket.

[0106] Step 6: Structure reset. The rotary motor 63 in the cooling mechanism 6 is started by the controller body 11 to make the sealing part 62 in the cooling mechanism 6 rotate and reset. Then the circulation mechanism 9 is started to pump the liquid in the unloading mechanism 7 to the cooling mechanism 6 to prepare for the subsequent processing of the molded products.

[0107] At this time, the product in the injection mold 4 is formed again. After the injection mold 4 is separated again, the multi-section electric push rod 69 is activated to drive the U-shaped cover 67 to move to the right and open. At this time, the adsorption plate 610 on the U-shaped cover 67 moves to the right in sync. When the U-shaped cover 67 moves, the splicing part 611 connected to it moves accordingly, causing the blower pipe 10 connected to it to also move.

[0108] The airflow released by the blower pipe 10 blows through the cavity of the fixed mold 47 in the injection mold 4, and repeats continuously.

[0109] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

8. A method of using an injection molding device for embedded iron parts according to any one of claims 1-7, characterized in that, The method includes the following steps: Step 1: Preparation. Start the blower mechanism (8) through the controller body (11) to achieve the blowing effect. At this time, the sealing part (62) in the cooling mechanism (6) realizes the aeration treatment of the liquid in the cooling box (61). The blower pipe (10) and the air guide component (76) in the unloading mechanism (7) are both in the air outlet state. Start the semiconductor cooling chip body (65) in the cooling mechanism (6). Then, according to the temperature sensor body, adjust the temperature of the liquid in the cooling box (61) to an appropriate state. Then start the conveying component (73) in the unloading mechanism (7). Under the transmission action of the transmission component (75), the airflow discharged by the air guide component (76) in the unloading mechanism (7) will continuously oscillate back and forth. Step 2: Embedded part injection molding. The controller body (11) controls the robotic arm body (5) to embed the iron part into the cavity of the moving mold (45) in the injection mold (4). Then, the controller body (11) starts the hydraulic cylinder (41) in the injection mold (4) to realize the closing of the moving mold (45) and the fixed mold (47) in the injection mold (4). Finally, the controller body (11) starts the injection unit (2) to realize the injection molding into the injection mold (4). Step 3: Demolding and unloading. After injection molding is completed, the program in the controller body (11) controls the hydraulic cylinder (41) in the injection mold (4) to open the moving mold (45) in the injection mold (4). When the moving mold (45) in the injection mold (4) is opened to the maximum mileage, the electric push rods (44) in the injection mold (4) are started to run simultaneously, driving the moving mold (45) in the injection mold (4) to move further to the left. When the hydraulic cylinder (41) in the injection mold (4) moves further to the left, the molded product in its cavity contacts the corresponding pusher (46) in the injection mold (4). With the help of the pusher (46), the molded product is pushed out of the corresponding cavity. The molded product that leaves the cavity falls directly into the cooling mechanism (6) under the action of gravity. Then, the robotic arm body (5) puts the new iron piece back into the cavity of the moving mold (45) in the injection mold (4). Step 4: Cooling and impurity removal. The controller body (11) activates the multi-section electric push rod (69) of the cleaning component in the cooling mechanism (6), causing the U-shaped cover (67) in the cooling mechanism (6) to move to the left along with the adsorption plate (610) in the cooling mechanism (6). During the movement, the U-shaped cover (67) in the cooling mechanism (6) uses the guide groove structure on the inner wall of the cooling tank (61) in the cooling mechanism (6) in conjunction with the telescopic plate (68) in the cooling mechanism (6) to lower the adsorption plate (610) in the cooling mechanism (6) when it reaches the maximum leftward distance. Then, the adsorption plate (610) in the cooling mechanism (6) comes into contact with the liquid surface in the cooling mechanism (6) to adsorb impurities floating on the liquid surface. At this time, as the cooling mechanism (6)... The displacement of the U-shaped cover (67) causes the splicing part (611) in the cooling mechanism (6) to drive the blower pipe (10) to slide laterally. During the movement, the blower pipe (10) blows and cleans the cavity of the fixed mold (47) in the injection mold (4). At this time, the controller body (11) drives the robotic arm body (5) to leave and drives the hydraulic cylinder (41) in the injection mold (4), so that the injection mold (4) closes. Then, the injection unit (2) is started to realize the injection of the new product. The liquid in the cooling box (61) in the cooling mechanism (6) gradually cools down under the action of the semiconductor cooling chip body (65) in the cooling mechanism (6), thereby realizing the gradual cooling treatment of the molded product entering the cooling box (61) in the cooling mechanism (6). Step 5: Product unloading. The rotary motor (63) in the cooling mechanism (6) is activated by the controller body (11), causing the sealing part (62) in the cooling mechanism (6) to rotate counterclockwise and open. When the sealing part (62) in the cooling mechanism (6) is open, the liquid in the cooling tank (61) in the cooling mechanism (6) and the molded product fall onto the mesh plate (72) in the unloading mechanism (7) under the action of gravity. At this time, the liquid directly passes through the mesh plate (72) in the unloading mechanism (7), while the molded product slides onto the conveying component (73) in the unloading mechanism (7). The operation of the conveying component (73) in the unloading mechanism (7) drives the movement of the molded product. The movement of the conveying component (73) in the unloading mechanism (7) drives the air guide component (76) in the unloading mechanism (7) to blow and dry the conveyed molded product through the transmission component (75) in the unloading mechanism (7). Then, the molded product falls onto the unloading plate (74) in the unloading mechanism (7) by the conveying component (73) in the unloading mechanism (7). Finally, the molded product on the unloading plate (74) in the unloading mechanism (7) slides down into the external collection basket. Step 6: Structure reset. The rotary motor (63) in the cooling mechanism (6) is started by the controller body (11) so that the sealing part (62) in the cooling mechanism (6) is rotated and reset. Then the circulation mechanism (9) is started to pump the liquid in the unloading mechanism (7) into the cooling mechanism (6) to prepare for the subsequent processing of the molded product. The cycle repeats.
