Description

Technical Field

[0001] This invention relates to the field of mold technology, and more specifically to a device for recycling waste material adhering to plastic molding molds. Background Technology

[0002] Injection molds, as molds for making plastic products, use the screw or plunger of injection molding equipment to inject viscous thermoplastic or thermosetting plastic melt into the cavity of a closed mold at high speed through the gating system under high pressure. Through thermodynamic actions such as cooling and shaping or cross-linking and solidification, 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 mold closing, due to factors such as injection pressure fluctuations, mold wear, or positioning deviations, molten plastic can easily seep into the parting line gap between the moving and fixed molds, forming flash, commonly known as "overflow," which stubbornly adheres to the parting line. The industry commonly uses manual scrapers or tools to manually remove flash from the parting line. This cleaning process is time-consuming, accounting for a significant portion of the production cycle and affecting equipment utilization. Furthermore, the cleaning effectiveness is affected by the operator's skill level. Residual flash can lead to poor mold closing later, causing defects such as burrs and dimensional deviations in the product. Additionally, the cleaned plastic waste cannot be collected and reused, resulting in resource waste. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides a device for recycling waste material adhering to plastic molding molds. This device effectively solves the problem that in existing technologies, when cleaning flash from molds, manual scrapers or tools are typically used to remove flash from the parting surface. This process is time-consuming and accounts for a large proportion of the production cycle, affecting equipment utilization. Furthermore, the cleaning effect is affected by the operator's skill level, and residual flash can lead to poor mold closure, resulting in defects such as burrs and dimensional deviations in the product.

[0043] The working principle and advantages of the plastic forming mold adhesive waste recycling device are as follows:

[0044] Injection molding process:

[0045] In actual working conditions, the operator drives the driving member 5 in the support frame 1 to drive the rotating frame 2 and the mold assembly 3 to rotate. When one of the mold assemblies 3 rotates to a predetermined injection molding station angle, the driving member 5 stops working, and at this time, the mold assembly 3 is in a horizontal position and is aligned with the output shaft of the injection molding system. The support frame 1, the rotating frame 2 and the mold assembly 3 are driven by the external translation mechanism to move to the output end of the injection molding system, and at the same time, the telescopic unit 6 in the support frame 1 pushes the movable mold 32 in the mold frame 31 to the direction of the fixed mold 33 until the movable mold 32 and the fixed mold 33 complete the mold closing action. Since the mold frame 31 is provided with a positioning member for aligning with the injection molding equipment, the center of the mold gate and the center of the injection nozzle can be coaxially aligned. This step ensures the basic coaxiality of the two through mechanical structure design, and at this time, the injection molding system injects the molten material into the cavity formed by the movable mold 32 and the fixed mold 33 through the gate. After the injection molding process is completed, the external translation mechanism drives the mold assembly to move away from the output end of the injection molding system.

[0046] It is worth noting that the driving member 5 can adopt gear transmission, belt transmission and other transmission forms to ensure the smooth and uniform rotation of the rotating frame 2 in the support frame 1. The present scheme adopts the form of linkage of driving motor and gear transmission mechanism, and the related parts of the driving member 5 are subjected to high temperature resistance treatment to avoid the rotation frame 2 from being stuck due to high temperature during the preheating process of the mold assembly 3, thereby affecting the alternating operation of the four mold assemblies 3.

[0047] Cooling process:

[0048] After the injection molding process is completed, the driving member 5 continuously drives the rotating frame 2 to rotate at a uniform speed along the central axis until the mold assembly 3 rotates to the set angle of the cooling station, and at the same time, the next mold assembly 3 rotates to the injection molding station. At this time, while the next mold assembly 3 is subjected to injection molding, the mold assembly 3 that has completed injection molding is cooled by using the time gap of the injection molding cycle by means of the built-in cooling system of the injection molding equipment, so as to promote the solidification and setting of the plastic parts in the mold cavity.

[0049] Demolding process:

[0050] When the plastic part in the mold assembly 3 is cooled and solidified, the driving member 5 continues to drive the rotating frame 2 and the mold assembly 3 to rotate until the mold assembly 3 is rotated to the unloading setting angle. At this time, the telescopic machine group 6 in the support frame 1 drives the movable mold 32 to move away from the fixed mold 33 in the opening direction until the maximum opening stroke is reached. In this process, the guide rod 42 in the movable mold 32 first contacts the bottom of the mold frame 31 (at this time, the movable mold 32 has not reached the maximum stroke position), and as the movable mold 32 continues to move, the guide rod 42 drives the abutment plate 41 to be relatively separated from the movable mold 32, and at the same time, the elastic member on the outer periphery of the guide rod 42 is compressed. When the abutment plate 41 is separated from the movable mold 32, the gradually increasing pushing force overcomes the adhesion force between the plastic part and the surface of the movable mold 32, so that the plastic part is gradually separated from the movable mold 32, and the plastic part falls into the material collecting area of the injection molding equipment, and the demolding process is completed.

[0051] It is worth noting that during the demolding process, the movable mold 32 is separated from the fixed mold 33 under the drive of the telescopic machine group 6, and at this time, the abutment plate 41 is in a non-contact state with the parting surface of the fixed mold 33. The elastic member on the outer periphery of the movable rod 46 promotes the displacement of the collecting frame 47 along the movable rod 46 in the axial direction, so that the collecting frame 47 is separated from the notch 43 on the surface of the abutment plate 41 and the fixed mold 33, but the collecting frame 47 is not completely separated from the notch 43, but forms a step structure with the inner wall of the notch 43. The step structure constitutes a mechanical stop, which effectively limits the displacement of the collecting frame 47 along the guide groove 44, and avoids the interference of the movement of the collecting frame 47 during the demolding process to the demolding process.

[0052] Cleaning process:

[0053] For some plastic materials with high melt viscosity, poor flowability or narrow melt temperature range, if the plastic overflow occurs on the parting surface of the fixed mold 33 and the movable mold 32 during the injection molding process, and the local solidification and adhesion occur due to the non-uniform cooling rate, the operator needs to use auxiliary tools to clean the overflow material adhered to the parting surface.

[0054] After the demolding process is completed, the driving member 5 drives the rotating frame 2 to continuously rotate the demolded mold assembly 3. In this process, the abutment plate 41 in the mold assembly 3 is gradually separated from the surface of the fixed mold 33 to form an inclined angle with the horizontal plane. Due to the step structure of the guide groove 44 and the inner wall of the notch 43, the movement of the collecting frame 47 is mechanically hindered, and as the rotating angle of the mold assembly 3 with the rotating frame 2 increases, the inclination of the abutment plate 41 and the fixed mold 33 gradually increases, and the collecting frame 47 overcomes the step resistance of the notch 43 under the action of the gravity component of the collecting frame 47, and moves linearly along the guide groove 44 with the slider 45, and at the same time, the slider 45 stretches the reset spring on the outside.

[0055] When the collecting frame 47 moves, the slope at the bottom of the collecting frame 47 is in close sliding contact with the surface of the fixed mold 33 and the butt joint plate 41, and the surface overflow is scraped by the slope shearing effect. During the sliding of the collecting frame 47 along the guide groove 44, the meshing of the transmission gear 482 and the rack 483 drives the transmission roller 481 to rotate, and the scraped overflow is transported into the collecting cavity 48 through the transmission roller 481. When the reset spring reaches the maximum stretching stroke, the collecting frame 47 stops moving, and thus the cleaning and collecting operation of the overflow on the surface of the butt joint plate 41 and the fixed mold 33 is completed. The mechanism design realizes the automatic collection of the overflow, facilitates the subsequent recycling and reuse, and effectively reduces the resource loss.

[0056] It is worth noting that the roller surface of the transmission roller 481 can be designed as any one of a spiral groove, a toothed structure and the like, and can better grasp the waste, and move the waste by using the friction force or mechanical force during rotation. In addition, the collecting cavity 48 is provided with a protrusion in close contact with the outer surface of the transmission roller 481, forming a dynamic stripping pair of “scraper-roller surface”. When the transmission roller 481 rotates, the protrusion generates a radial extrusion force on the residual overflow adhered to the groove of the roller surface, and the waste particles are stripped from the roller surface by using the difference in elastic deformation of the material.

[0057] 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 collecting frame 47 disappears, and under the action of the reset spring, the collecting frame 47 is reset along the guide groove 44 in cooperation with the sliding block 45, until it moves to the slot 43 position. As the telescopic machine set 6 moves the movable mold 32 towards the fixed mold 33, the movable mold 32 and the fixed mold 33 re-complete the mold closing action. During the mold closing process, under the action of the extrusion force between the fixed mold 33 and the movable mold 32, the collecting frame 47 re-adjoins the slot 43. When the collecting frame 47 completely enters the slot 43, the surface of the butt joint plate 41 and the fixed mold 33 forms a complete plane, ensuring that the mold closing accuracy is not affected.

[0058] When the two collecting frames 47 are in close contact with each other, the magnetic element in the movable plate 49 stops working. The magnetic element is an electromagnet which is treated with high temperature resistance. Under the action of its own gravity, the movable plate 49 overcomes the pre-tightening force threshold of the torsional spring, rotates downward along the pin shaft axis, forms a material passage between the two collecting frames 47, and makes the waste in the “upper layer” collecting cavity 48 enter the “lower layer” collecting cavity 48 through the passage, so as to realize the centralized collection of the waste and facilitate the secondary use of the waste by the operator.

[0059] After the waste falls from the upper layer collecting cavity into the lower layer collecting cavity, the electromagnetic device remains in the energized state, and at this time, the movable gate plate is reset to the initial position, so that the collecting cavity restores the closed state. Through repeated operation of the above operation, the cycle operation process of “injection molding-cooling and shaping-ejection and taking out-waste cleaning” is realized.

[0060] The cleaning element 4 adopted in the present application has the following advantages:

[0061] Advantage one, multi-mold assembly 3 cycle operation, improve production efficiency, four along the center of the rotating frame 2 circumferential array distribution of mold assembly 3, through the drive motor and transmission mechanism rotating frame 2 rotation, make mold assembly 3 in turn through injection, cooling, blanking, cleaning station. For example, when a mold assembly 3 in injection, another can be synchronized cooling, use time interval to achieve "injection molding, cooling, demolding, waste cleaning" cycle, reduce equipment idle, improve production efficiency.

[0062] Advantage two, automatic cleaning waste, reduce labor costs and labor intensity, when the mold assembly 3 rotates to the preset cleaning angle, cleaning piece 4 automatically starts. The collection frame 47 in the cleaning piece 4 slides under the action of the gravity component force generated by the rotation of the mold assembly 3, and the bottom slope thereof slides with the surface of the fixed mold 33 and the butt joint plate 41, and the overflow on the parting surface is scraped through the shear effect of the slope. At the same time, the transmission roller 481 is driven to rotate by the meshing of the transmission gear 482 and the rack 483, and the waste is transported to the collection cavity 48, without manual cleaning, avoiding the low efficiency and high intensity labor of manual operation, and reducing the labor cost.

[0063] Advantage three, waste collection and transmission design, convenient for recycling, the collection cavity 48 is arranged in the collection frame 47, and the scraped waste can be transported into the collection cavity 48 when the transmission roller 481 rotates. The bottom of the collection frame 47 is designed as a slope, which is beneficial to the concentration of waste in the collection cavity 48. When the two collection frames 47 are attached, the magnetic element in the movable plate 49 stops working, the movable plate 49 rotates under the action of gravity, forming a material channel, so that the waste in the upper collection cavity 48 falls into the lower collection cavity 48, realizing waste collection, facilitating subsequent unified treatment and recycling, and reducing the waste of polymer material resources.

[0064] Advantage four, the protrusion cooperates with the transmission roller 481 to prevent waste residue, the protrusion attached to the transmission roller 481 is fixedly connected in the collection cavity 48, forming a dynamic stripping pair of "scraper-roller surface". When the transmission roller 481 rotates, the protrusion generates a radial extrusion force on the residual overflow adhered in the groove of the roller surface, and the waste particles are stripped from the roller surface by using the difference in elastic deformation of the material, so as to fall into the collection cavity 48, prevent waste residue on the transmission roller 481, and ensure the normal work of the transmission roller 481 and the thoroughness of waste collection.

[0065] The fifth advantage is that the elastic member and the reset spring are designed to ensure stable reset of the mechanism. The outer surface of the guide rod 42 is provided with an elastic member. When the movable mold 32 moves during demolding, the guide rod 42 drives the abutting plate 41 to separate from the movable mold 32, the elastic member is compressed, and a buffer force is provided to overcome the adhesion between the plastic part and the movable mold 32, so as to facilitate demolding of the plastic part. At the same time, the outer surface of the movable rod 46 is sleeved with a reset spring. After the cleaning operation is completed, when the mold assembly 3 is in a horizontal position, the reset spring drives the collecting rack 47 to reset along the guide groove 44, so as to ensure that the collecting rack 47 returns to the initial position and is attached to the notch 43, so as to ensure that the mold closing precision is not affected, and the mechanism can stably perform the cyclic operation.

[0066] The sixth advantage is that when the two collecting racks 47 are rotated to the attached state with the mold assembly 3, the magnetic member in the movable plate 49 stops working, the movable plate 49 rotates downward along the pin shaft under the action of its own gravity and overcomes the pre-tightening force of the torsional spring, and a material passage is formed between the two collecting racks 47. At this time, the waste in the “upper” collecting rack 47 can fall into the collecting cavity 48 of the “lower” collecting rack 47 through the passage, so as to realize centralized storage of the waste. Through centralized collection, the waste in the two collecting racks 47 is combined into one cavity, so as to reduce the cleaning frequency of the collecting rack 47.

[0067] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalent ones. Such modifications or replacements will not change the essence of the corresponding technical solutions out of the protection scope of the technical solutions of the embodiments of the present application.
