Description

Technical Field

[0001] The invention relates to the technical field of molds, and in particular to a device for recycling waste materials adhered to plastic molding molds. Background Art

[0002] As a mold for forming plastic products, the injection mold uses the screw or plunger of the injection molding equipment to inject the thermoplastic or thermosetting plastic melt in a viscous flow state into the cavity of the closed mold at high speed through the pouring system under high pressure. After thermodynamic effects such as cooling and shaping or cross-linking and curing, the melt completes the mold filling, pressure holding, cooling and crystallization process, and finally obtains a plastic part with a predetermined geometric shape, dimensional accuracy and functional characteristics.

[0003] During the mold closing process, due to factors such as injection pressure fluctuations, mold wear, or positioning deviations, molten plastic can easily penetrate the gap between the moving and fixed molds, forming flash, commonly known as "flash," which stubbornly adheres to the parting surface. The industry generally uses scrapers or other tools to manually remove flash from the parting surface. This cleaning process consumes a significant portion of the production cycle, affecting equipment utilization. Furthermore, the effectiveness of the cleaning process is affected by the operator's skill level. Residual flash can lead to subsequent loose mold closing, causing defects such as burrs and dimensional deviations. Furthermore, the cleaned plastic waste cannot be collected and reused, resulting in a waste of resources. Summary of the Invention

[0022] The docking plate 41 and the fixed mold 33 are respectively provided with a slot 43 on one side close to each other.

[0023] The bottom of the collecting rack 47 is designed to be inclined, and a collecting chamber 48 for storing waste is provided in the collecting rack 47. A transmission roller 481 is rotatably connected in the collecting chamber 48, and a transmission gear 482 is fixedly connected to the end of the transmission roller 481. The docking plate 41 and the fixed mold 33 are fixedly connected to one side close to each other with a rack 483 meshing with the transmission gear 482, and a protrusion is fixedly connected in the collecting chamber 48 to fit with the transmission roller 481.

[0024] The collection rack 47 is rotatably connected to a movable plate 49 via a pin arranged on the side away from the transmission roller 481. A torsion spring is sleeved on the outer surface of the pin. A magnetic part is fixedly connected to the inside of the movable plate 49, and the magnetic part is connected to the inner wall of the collection chamber 48 by magnetic force.

[0025] The working principle and advantages of the recycling device for waste materials adhered to plastic molding molds: Injection molding process: In actual operation, the operator manipulates the driver 5 within the support frame 1 to cause the rotating frame 2 and mold assembly 3 to rotate in unison. When one mold assembly 3 reaches the predetermined injection position, the driver 5 stops, and the mold assembly 3 assumes a horizontal position, aligned with the axis of the injection molding system output. Driven by an external translation mechanism, the support frame 1, rotating frame 2, and mold assembly 3 move together toward the injection molding system output. Simultaneously, the telescopic mechanism 6 within the support frame 1 pushes the movable mold 32 in the mold frame 31 toward the fixed mold 33 until the movable and fixed molds 33 are closed. Because the mold frame 31 is equipped with locating members that align with the injection molding equipment, the center of the mold gate is coaxially aligned with the center of the injection molding machine nozzle. This step ensures the basic coaxiality required between the two through mechanical design. The injection molding system then injects the molten material through the gate into the cavity formed by the movable and fixed molds 32, 33. After the injection molding process is completed, the external translation mechanism drives the mold 32 assembly away from the injection molding output.

[0026] It is worth noting that the drive element 5 can adopt a gear drive, belt drive, or other transmission methods to ensure that the rotating frame 2 rotates smoothly and uniformly within the support frame 1. This solution uses a drive motor and a gear transmission mechanism in conjunction with each other, and the relevant components of the drive element 5 are treated to withstand high temperatures to prevent the rotating frame 2 from seizing due to high temperatures during the preheating of the mold assemblies 3, which would affect the alternating operation of the four sets of mold assemblies 3.

[0027] Cooling process: After the injection molding process is completed, the driving member 5 continues to drive the rotating frame 2 to rotate at a uniform speed along its central axis until the mold assembly 3 rotates to the cooling station setting angle, and the next mold assembly 3 is synchronously rotated to the injection molding station. At this time, while the next mold assembly 3 is being injection molded, the injection molding equipment's built-in cooling system is used to cool the mold assembly 3 that has completed the injection molding during the time interval of the injection molding cycle, so as to promote the solidification and shaping of the plastic part in the mold cavity.

[0028] Demolding process: After the plastic part within the mold assembly 3 has cooled and solidified, the drive unit 5 continues to rotate the rotating frame 2 and mold assembly 3 until the mold assembly 3 reaches the set angle for blanking. At this point, the telescopic mechanism 6 within the support frame 1 drives the movable mold 32 away from the fixed mold 33 in the mold opening direction until it reaches its maximum mold opening stroke. During this process, the guide rods 42 within the movable mold 32 first contact the bottom of the mold frame 31 (at this point, the movable mold 32 has not yet reached its maximum stroke position). As the movable mold 32 continues to move, the guide rods 42 drive the docking plate 41 to separate from the movable mold 32, while the elastic members around the guide rods 42 are compressed. As the docking plate 41 separates from the movable mold 32, the increasing thrust overcomes the adhesion between the plastic part and the surface of the movable mold 32, causing the plastic part to gradually detach from the movable mold 32. The detached plastic part falls into the collection area of ​​the injection molding machine, completing the demolding process.

[0029] It is worth noting that during the demolding process, the movable mold 32, driven by the telescopic unit 6, separates from the fixed mold 33. At this point, the butt plate 41 and the parting surface of the fixed mold 33 remain in a non-contact state. The elastic member on the outer periphery of the movable rod 46 causes the collection rack 47 to move axially along the movable rod 46. Although this disengages the collection rack 47 from the notch 43 between the butt plate 41 and the fixed mold 33, it does not completely escape from the notch 43. Instead, it forms a step structure with the inner wall of the notch 43. This step structure constitutes a mechanical stop, effectively limiting the displacement of the collection rack 47 along the guide slot 44 and preventing any movement of the collection rack 47 during demolding from interfering with the demolding process.

[0030] Cleaning process: For some plastic materials with high melt viscosity, poor fluidity or a narrow melting temperature range, during the injection molding process, if the plastic overflows onto the parting surface between the fixed mold 33 and the movable mold 32, and local premature solidification and adhesion occur due to uneven cooling rate, the operator needs to use auxiliary tools to clean the overflow adhered to the parting surface. After the demolding process is complete, the drive member 5, in conjunction with the rotating frame 2, continues to rotate the demolded mold assembly 3. During this process, the docking plate 41 in the mold assembly 3 and the surface of the fixed mold 33 gradually form an inclined angle with the horizontal plane. Because the stepped structure between the guide groove 44 and the inner wall of the notch 43 mechanically hinders the movement of the collection frame 47, as the rotation angle of the mold assembly 3 with the rotating frame 2 increases, the inclination of the docking plate 41 and the fixed mold 33 gradually intensifies. Under the action of its own weight component, the collection frame 47 overcomes the step resistance of the notch 43 and produces a linear displacement along the guide groove 44 along with the slider 45, while the slider 45 simultaneously stretches the outer return spring. As the collection rack 47 moves, the inclined surface at its bottom slides against the surfaces of the fixed mold 33 and the docking plate 41, scraping away any surface spillage through the shearing effect of the inclined surface. As the collection rack 47 slides along the guide groove 44, the meshing of the transmission gear 482 and the rack 483 drives the transfer roller 481, which then conveys the scraped spillage into the collection chamber 48. When the return spring reaches its maximum extension stroke, the collection rack 47 stops, completing the cleaning and collection of spillage from the docking plate 41 and fixed mold 33. This mechanical design enables automated collection of spillage, facilitating subsequent recycling and reuse, effectively reducing resource loss. It's worth noting that the surface of the conveyor roller 481 can be designed with any texture or shape, such as spiral grooves or tooth structures, to better grasp the waste and move it using friction or mechanical force during rotation. Furthermore, the collection chamber 48 is equipped with protrusions that mate with the outer surface of the conveyor roller 481, forming a "scraper-roller" dynamic stripping pair. As the conveyor roller 481 rotates, the protrusions exert radial pressure on any residual material adhering to the grooves on the roller surface, peeling the waste particles from the roller surface by leveraging the material's differential elastic deformation.

[0031] After the cleaning operation is completed, as the mold assembly 3 continues to rotate, when the mold assembly 3 is in a horizontal position, the gravity component of the collection rack 47 disappears. Under the action of the reset spring, the collection rack 47 cooperates with the slider 45 to perform a reset movement along the guide groove 44 until it moves to the position of the notch 43. As the telescopic unit 6 moves the movable mold 32 toward the fixed mold 33, the movable mold 32 and the fixed mold 33 complete the mold closing action again. During the mold closing process, under the action of the extrusion force between the fixed mold 33 and the movable mold 32, the collection rack 47 re-fits with the notch 43. When the collection rack 47 fully enters the notch 43, the surface of the docking plate 41 and the fixed mold 33 form a complete plane, ensuring that the mold closing accuracy is not affected. When the two collection racks 47 are aligned, the magnetic element within the movable plate 49, an electromagnet with a high-temperature resistance treatment, stops operating. Under its own weight, the movable plate 49 overcomes the preload threshold of the torsion spring and rotates downward along the axis of the pin, forming a material channel between the two collection racks 47. This channel allows waste material in the "upper" collection chamber 48 to enter the "lower" collection chamber 48, achieving centralized collection of the waste and facilitating subsequent secondary use by the operator.

[0032] When the waste material falls from the upper collection chamber into the lower collection chamber, the electromagnetic device remains energized, and the movable gate returns to its initial position, restoring the collection chamber to its sealed state. By repeating this operation, the "injection molding - cooling and shaping - demoulding and removing the parts - waste material cleaning" cycle is achieved.

[0033] The present invention adopts the cleaning member 4, which has the following advantages: Advantage 1: Multiple mold assemblies 3 operate in a circular pattern, improving production efficiency. Four mold assemblies 3 are arranged in an array along the central circumference of the rotating frame 2. Driven by a drive motor and transmission mechanism, the rotating frame 2 rotates, causing the mold assemblies 3 to sequentially pass through the injection, cooling, unloading, and cleaning stations. For example, while one mold assembly 3 is injecting, another can be cooled simultaneously. This time gap allows the "injection molding, cooling and setting, demolding, and waste cleaning" cycle to be completed, reducing equipment idle time and improving production efficiency.

[0034] The second advantage is automated waste cleaning, reducing labor costs and labor intensity. When the mold assembly 3 rotates to the preset cleaning angle, the cleaning unit 4 automatically activates. Under the action of the gravity component force generated by the rotation of the mold assembly 3, the collection rack 47 in the cleaning unit 4 slides along the guide groove 44. Its bottom inclined surface slides in contact with the surface of the fixed mold 33 and the docking plate 41, scraping off the overflow from the parting surface through the inclined shear effect. At the same time, the transmission gear 482 engages with the rack 483 to drive the transmission roller 481 to rotate, conveying the waste to the collection chamber 48, eliminating the need for manual cleaning, avoiding the inefficiency and high labor intensity of manual operation, and reducing labor costs.

[0035] Advantage three: The waste collection and transfer design facilitates recycling and reuse. A collection chamber 48 is provided within the collection rack 47. The rotation of the transfer roller 481 conveys scraped waste into the collection chamber 48. The sloped bottom of the collection rack 47 facilitates the collection of waste into the collection chamber 48. When the two collection racks 47 are aligned, the magnetic components within the movable plate 49 stop functioning, and the movable plate 49 rotates under gravity, forming a material channel that allows waste from the upper collection chamber 48 to fall into the lower collection chamber 48. This enables centralized waste collection, facilitates subsequent unified processing and recycling, and reduces waste of polymer material resources.

[0036] Advantage 4: The protrusions cooperate with the conveyor roller 481 to prevent waste residue. The protrusions, fixedly connected to the conveyor roller 481 within the collection chamber 48, form a dynamic "scraper-roller" stripping mechanism. As the conveyor roller 481 rotates, the protrusions exert radial pressure on any residual material adhering to the grooves on the roller surface. This leverages the material's differential elastic deformation to peel waste particles from the roller surface and drop them into the collection chamber 48, preventing waste from remaining on the conveyor roller 481 and ensuring proper functioning of the conveyor roller 481 and thorough waste collection.

[0037] Advantage five: The elastic member and return spring design ensures stable reset of the mechanism. The outer surface of the guide rod 42 is equipped with an elastic member. When the movable mold 32 moves during demolding, the guide rod 42 drives the docking plate 41 and the movable mold 32 to separate relative to each other. The elastic member is compressed, providing a buffering force to overcome the adhesion between the plastic part and the movable mold 32 and facilitate demolding. Simultaneously, the outer surface of the movable rod 46 is sheathed with a return spring. After cleaning is completed, when the mold assembly 3 is in a horizontal position, the return spring drives the collection rack 47 to return along the guide groove 44, ensuring that the collection rack 47 returns to its original position and fits into the notch 43. This ensures that the mold clamping accuracy is not affected and enables the mechanism to perform stable cycle operations.

[0038] Advantage six: When the two collection racks 47 rotate with the mold assembly 3 to a close fit, the magnetic element in the movable plate 49 stops functioning. Under its own weight, the movable plate 49 overcomes the preload of the torsion spring and rotates downward along the pin, forming a material channel between the two collection racks 47. At this point, waste material in the "upper" collection rack 47 can fall through the channel into the collection chamber 48 of the "lower" collection rack 47, achieving centralized storage of waste material. This centralized collection combines waste material from both collection racks 47 into a single chamber, reducing the frequency of cleaning the collection racks 47.
