Technical Field

[0001] This invention relates to the field of injection molding machine technology, and more specifically to a fully automatic injection molding machine that provides uniform mold cooling. Background Technology

[0002] Plastics are the most widely used organic polymer materials in modern society, obtained through polymerization reactions from petroleum / natural gas. Thermoplastics soften when heated and harden when cooled, allowing for repeated processing and are widely used in medical, packaging, electronics, automotive, and construction fields.

[0038] The lower ends of the first half-module 22 and the second half-module 23 are each fixedly assembled with two fixing blocks 24, and each fixing block 24 is fixedly provided with a sliding block 25 at its lower end. Two sliding blocks 25 on adjacent and different components are slidably arranged on the same sliding track 26. Both sliding tracks 26 are horizontally arranged on the upper surface of the support bracket 1.

[0039] In a preferred embodiment, the injection mold 2 can fix different templates to perform injection molding of plastic products. At the same time, the template used in this device is a double-layer template, that is, the back and front of the template have the same shape, so that the cooling group on the injection mold 2 can fully contact the injected plastic, thereby ensuring that the distance between each position of the product and the cooling unit is consistent, making the cooling more uniform, thereby improving product quality and reducing the defect rate. The demolding auxiliary mechanism 4 can clean the template before injection molding to remove dust or plastic that may stick to the template. Then, the demolding auxiliary mechanism 4 will spray a release agent onto the template to facilitate the subsequent demolding work. In the subsequent demolding process, the demolding auxiliary mechanism 4 will also remove the product and place it safely on the product conveyor belt 5, thereby realizing the automated production of the product.

[0040] The first half-module 22 and the second half-module 23 can fit together to form a product cavity, thereby allowing the molten plastic to be molded. The first half-module 22 and the second half-module 23 are slidably mounted on the horizontal sliding column 21, so that they can move under the drive of the sliding block 25. This allows for active adjustment of the distance between the first half-module 22 and the second half-module 23, facilitating the disassembly of the template. At the same time, the position can also be adjusted so that the product is placed between the observation and debugging doors 6 during the molding process, allowing the staff to observe the production status at any time.

[0041] Furthermore, the first half-module 22 includes:

[0042] The first fixed groove 221 is a square component, and each of the four corners is provided with a first through hole 222. A linear bearing is fixedly assembled in each first through hole 222 and is slidably mounted on the four horizontal sliding columns 21 respectively.

[0043] The first fixing groove 221 has a cavity on the side away from the raw material injection component 3, and a first template fixing step 223 is provided inside it. Multiple first fixing posts 224 are horizontally fixed on the first template fixing step 223. First threaded countersunk holes 225 are provided on the four sides of the first fixing groove 221 on the side away from the raw material injection component 3.

[0044] A first sealing gasket 226 is fixedly embedded on the side of the first fixing groove 221 away from the raw material injection assembly 3;

[0045] The injection connecting rod 227 is horizontally fixedly embedded in the middle of the first fixing groove 221;

[0046] In a preferred embodiment, the first fixing post 224 and the first threaded countersunk hole 225 can fix the template on the first fixing groove 221 from multiple directions, avoiding misalignment and product defects. The first template fixing step 223 can support the template and reserve a cavity to facilitate smoke exhaust, thereby improving product quality.

[0047] Furthermore, the second half-module 23 includes:

[0048] The second fixing groove 231 is a square component, and each of the four corners is provided with a second through hole 232. A linear bearing is fixedly installed in each second through hole 232 and is slidably mounted on the four horizontal sliding columns 21 respectively.

[0049] The second fixing groove 231 has a cavity on the side near the raw material injection component 3, and a second template fixing step 233 is provided inside. Multiple second fixing posts 234 are horizontally fixed on the second template fixing step 233. Second threaded countersunk holes 235 are provided on the four sides of the second fixing groove 231 on the side near the raw material injection component 3.

[0050] A second sealing gasket 236 is fixedly embedded in the side cavity of the second fixing groove 231 near the raw material injection assembly 3;

[0051] The product cooling component 237 is horizontally fixedly embedded in the middle of the second fixing groove 231;

[0052] In a preferred embodiment, the product cooling component 237 can fully contact the injected plastic, thereby ensuring that the distance between each position of the product and the cooling unit remains consistent, making the cooling more uniform, thereby improving product quality and reducing the defect rate in production.

[0053] Furthermore, the first sealing gasket 226 and the second sealing gasket 236 are mirror images of each other;

[0054] In a preferred embodiment, the arrangement of the first sealing gasket 226 and the second sealing gasket 236 can increase the sealing degree between the first half-module 22 and the second half-module 23, thereby preventing molten plastic from overflowing, causing waste of resources and the generation of defective products.

[0055] Furthermore, the product cooling assembly 237 includes:

[0056] A cooling fan 2376 is fixedly embedded in the second fixing groove 231 on the side away from the raw material injection assembly 3. Two coolant tanks 2371 are fixedly installed on the side of the cooling fan 2376 near the raw material injection assembly 3. Four heat conduction pipes 2372 are horizontally arranged between the two coolant tanks 2371. Multiple heat conduction branches are evenly arranged on the side of each heat conduction pipe near the raw material injection assembly 3. Fixing seats 2374 are fixedly installed on the multiple heat conduction branches, and a telescopic heat conduction rod 2375 is slidably installed in each heat conduction branch.

[0057] Multiple heat dissipation fins 2373 are vertically arranged and evenly fixed between the cooling fan 2376 and the four heat pipes 2372;

[0058] In a preferred embodiment, the telescopic heat-conducting rod 2375 can extend to contact the back of the template, thereby evenly distributing the telescopic heat-conducting rod 2375 on the back of the template. This allows the molten plastic to be evenly conducted through the back plate and the telescopic heat-conducting rod 2375 on the back plate to the heat-conducting pipe 2372, and then fully evaporated through the heat dissipation fins 2373. The cooling fan 2376 can further accelerate the heat dissipation of the heat dissipation fins 2373, thereby further improving the production efficiency of the device. The coolant in the coolant tank 2371 can absorb as much heat as possible, thus facilitating heat dissipation.

[0059] Furthermore, each of the coolant tanks 2371 is equipped with a pressure booster;

[0060] In a preferred embodiment, the pressure device can be configured to allow the telescopic heat-conducting rod 2375 to fully extend and retract under pressure, thereby maximizing its contact with the back of the template and facilitating heat dissipation.

[0061] Furthermore, the demolding auxiliary mechanism 4 includes a dustproof shell 41, which is fixedly disposed on the upper surface of the main dustproof shell 7. A support base 42 is disposed inside the dustproof shell 41, which is fixedly assembled on the upper surface of the main dustproof shell 7. A three-stage moving group 43 is fixedly assembled on the upper surface of the support base 42, and an auxiliary component 44 is fixedly assembled on the lower surface of the vertical moving end of the three-stage moving group 43.

[0062] In a preferred embodiment, the auxiliary component 44 can clean the template under the action of the three-stage moving group 43, thereby removing dust or possibly sticky plastic from the template. It can also spray a release agent onto the template to facilitate subsequent demolding. In the subsequent demolding process, the auxiliary component 44 will also remove the product and place it safely on the product conveyor belt 5, thereby realizing automated production of the product and further improving production efficiency.

[0063] Furthermore, the auxiliary component 44 includes a first drive motor 441, which is fixedly mounted on the lower surface of the vertical moving end of the three-stage moving group 43. A rotating support platform 442 is fixedly mounted on the output shaft of the first drive motor 441. Three rotating arms 443 are rotatably arranged on the upper surface of the rotating support platform 442, and a second drive motor 444 is arranged between each rotating arm 443 and the rotating support platform 442.

[0064] The three rotating arms 443 are respectively equipped with a cleaning brush 445, a sprayer 446 and a fixed suction cup 447 at the ends away from the rotating support platform 442;

[0065] In a preferred embodiment, the second drive motor 444 can drive the corresponding rotating arm 443 to rotate, so that the rotating arm 443 can be retracted when not in use, which facilitates the operation of the device. At the same time, it prevents the rotating arm 443 that is not in use from obstructing the operation of the rotating arm 443 that should be used during operation. The first drive motor 441 can drive the rotating support platform 442 to rotate, thereby performing different steps of operation.

[0066] The specific implementation includes the following steps: First, the completed template is fixed inside the injection mold 2, and the data of the injection mold 2 is adjusted according to the actual situation. Then, the demolding auxiliary mechanism 4 is driven to clean the template of the injection mold 2 to remove surface dust and impurities. Then, a release agent is sprayed onto the template of the injection mold 2. Plastic raw materials are added into the raw material injection component 3, which melts the raw materials. Then, it is pushed forward under high pressure to inject the molten plastic into the injection mold 2 at high speed and high pressure. After the mold is filled, the raw material injection component 3 continues to apply a lower pressure to replenish the melt into the injection mold 2. After the plastic in the mold changes from molten state to solid state, the raw material injection component 3 retreats while melting new plastic particles to prepare for the next mold. At the same time, the demolding auxiliary mechanism 4 is driven to remove the product from the injection mold 2 and place it on the product conveyor belt 5. The product is then output through the product conveyor belt 5.

[0067] The above description is merely a preferred embodiment 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.
