Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automated equipment, and specifically relates to a material pushing device. Background Technology
[0002] In traditional secondary injection molding processes, production is typically carried out in discrete steps, meaning that steps such as initial injection, cooling, and unloading need to be completed by transferring between different equipment or workstations. Each step requires independent operation, resulting in long production cycles, low efficiency, and large equipment space requirements. Furthermore, after secondary injection molding, the product is tightly bonded to the mold, and traditional robotic arms or manual clamping can easily cause surface damage or contamination when unloading the product, and demolding accuracy is difficult to guarantee. At the same time, manual intervention requires frequent contact with high-temperature molds and semi-finished products, which can easily lead to surface contamination of the product and pose safety hazards.

Detailed Implementation
[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0033] like Figure 1-3As shown, this utility model provides a material ejection device, including a frame 1. The frame 1 is equipped with an injection molding mechanism 2, a turret 3, and an ejection mechanism 4. The turret 3 includes a lifting assembly 31, a first driving component 32, a main rotating shaft 33, and a rotating component 34 coaxially connected to the main rotating shaft 33. The frame 1 has a first injection position 11, a cooling position 12, a second injection position 13, and a discharge position 14 arranged sequentially around the turret 3. The lifting assembly 31 drives the main rotating shaft 33 and the rotating component 34 to rise and fall, disengaging the product 6 mounted on the rotating component 34 from the first injection position 11 and the second injection position 13. The first driving component 32 drives the main rotating shaft 33 and the rotating component 34 to rotate. In use, the injection molding mechanism 2 closes the mold and performs injection molding to form a semi-finished product. The semi-finished product is integrally formed with the rotating component 34. The injection molding machine... The injection mechanism 2 opens, and then the lifting assembly 31 drives the rotating part 34 to rise, causing the semi-finished product to completely detach from the injection mechanism 2. Subsequently, the first driving part 32 drives the main rotating shaft 33 to rotate, causing the rotating part 34 and the semi-finished product to rotate to the cooling position 12 for cooling. After cooling, the first driving part 32 drives the rotating part 34 and the semi-finished product to rotate to the second injection position 13 for secondary injection molding and mold closing, forming the product 5. The injection mechanism 2 opens, and then the rotating part 34 drives the product 5 to detach from the injection mechanism 2 under the drive of the lifting assembly 31. The first driving part 32 drives the rotating part 34 to rotate the product 5 to the unloading position 14, so that the product 6 sequentially switches between the first injection position 11, the cooling position 12, the second injection position 13 and the unloading position 14.
[0034] The ejection mechanism 4 includes an ejection plate 41 and a second driving member 42. In use, the output shaft of the second driving member 42 is connected to the ejection plate 41 to drive the ejection plate 41 to eject the product 5 located at the unloading position 14 and separate it from the rotating member 34. This sequentially realizes the first injection molding, cooling, second injection molding and unloading of the product 5. This design structure is simple. Through the design of the turret 3, the traditional discrete process is transformed into a continuous manufacturing process. At the same time, the ejection mechanism 4 is set to unload and demold the product 5, which solves the problems of difficult demolding in traditional second injection molding and the need for manual clamping or robotic unloading. It avoids the problems of surface contamination caused by manual contact or the need to occupy a large workspace. While ensuring the molding quality, it significantly improves the production cycle.
[0035] Specifically, such as Figure 4As shown, the rotating component 34 includes a turntable 341 with a connecting hole 3411. The main rotating shaft 33 has an annular groove 331 that matches the shape of the connecting hole 3411. The annular groove 331 is interlocked with the connecting hole 3411 to fix the turntable 341 to the main rotating shaft 33. This design simplifies the assembly process and facilitates disassembly and replacement of components. In this embodiment, the turntable 341 is circular. By setting the turntable 341, the force is evenly distributed, reducing shaking during operation.
[0036] It is important to note that, such as Figure 5 As shown, the rotating component 34 also includes mounting components 342. The mounting components 342 are fixedly connected to the turntable 341 in a circular array. This circular array optimizes space utilization, resulting in a compact equipment structure. The mounting components 342 are correspondingly arranged with the first injection position 11, cooling position 12, second injection position 13, and unloading position 14. The mounting components 342 at adjacent positions are perpendicular to each other. Each turntable 341 completes multiple steps of a product 5 with one rotation, enabling simultaneous injection molding, cooling and shaping, secondary injection molding, and ejection unloading. This improves production cycle time, significantly increases production efficiency, and optimizes space utilization. Continuous production is possible, and each mounting component 342 can be replaced or maintained individually without affecting the overall structure, reducing downtime. During operation, the turntable 341 rotates 90 degrees each time, with all four stations working simultaneously. Each cycle can complete one product. Since the mounting components 342 correspond to each station, precise positioning of each station can be ensured, reducing errors during movement. This design improves the stability and reliability of the system because each station has a fixed mounting point, reducing the need for robotic arms or other moving parts. The evenly distributed mounting components 342 can balance the dynamic balance of the turntable 341, reducing vibration during high-speed rotation, thereby improving the overall stability and lifespan of the machine.
[0037] It should be noted that the mounting component 342 is made of a high-temperature resistant and wear-resistant material. During the injection molding process, the integrated molding design of the mounting component 342 and the product 5 needs to take into account temperature changes and mechanical stress, improve positioning accuracy, enhance system rigidity, reduce vibration and noise, and improve load capacity.
[0038] like Figure 6 As shown, the injection molding mechanism 2 includes a front mold 21 and a rear mold 22. The rear mold 22 is provided with a through hole 221. A sliding member 222 is provided in the through hole 221. The sliding member 222 is sleeved on the outer peripheral wall of the main rotating shaft 33 and rotatably connected to the main rotating shaft 33.
[0039] Specifically, such as Figure 7-8As shown, the ejector plate 41 is provided with an ejector block 43, and the ejector block 43 is provided with a groove 431 that is adapted to the shape of the mounting member 342. In use, the mounting member 342 reaches the groove 431 under the action of the lifting assembly 31, and the ejector block 43 is ejected along with the ejector plate 41 under the action of the second driving member 42, thereby ejecting the product 5 from the mounting member 342. Because the groove 431 on the ejector plate 41 is adapted to the shape of the mounting member 342, the ejector block 43 can be accurately inserted into the corresponding position of the mounting member 342, applying an ejection force to make the product 5 detach from the mounting member 342. The entire process requires synchronous control to ensure that the ejection timing is coordinated with the rotation and lifting of the turret 3. In this embodiment, when the product 5 rotates to the unloading position 14, the lifting component 31 descends, the ejection mechanism 4 pushes the product 5 out, and the injection molding mechanism 2 closes the mold to perform injection molding. The shape-adaptive groove 431 design can ensure accurate ejection position, reduce deviation, and improve ejection success rate. This design can reduce wear on the mounting part 342 or the mold during ejection and extend the equipment life. In addition, the close fit between the ejection block 43 and the mounting part 342 may help to quickly change molds and improve production efficiency.
[0040] Furthermore, such as Figure 7 As shown, the ejection mechanism 4 also includes a connector 44 and a guide post 45. One side of the connector 44 is fixedly connected to the output shaft of the second drive member 42, and the other side is fixedly connected to one end of the guide post 45. The other end of the guide post 45 is fixedly connected to the ejection plate 41. By setting the guide post 45, the movement direction of the ejection plate 41 is constrained. At the same time, a connecting seat 46 is provided between the connector 44 and the ejection plate 41. The connecting seat 46 is fixedly connected to the injection molding mechanism 2. The guide post 45 passes through the connecting seat 46 and is fixedly connected to the connector 44 and the ejection plate 41. By setting the connecting seat 46, the movement direction of the guide post 45 is restricted, preventing the guide post 45 from shaking during movement, and realizing the smooth movement of the ejection plate 41.
[0041] Specifically, such as Figure 9-10 As shown, the lifting assembly 31 includes a first fixing plate 311, a second fixing plate 312, and a connecting column 313. One end of the connecting column 313 passes through the first fixing plate 311 and is fixedly connected to the second fixing plate 312, and the other end is fixedly connected to the rear mold 22. The second fixing plate 312 is fixed to the rear mold 22 by the connecting column 313. This design saves space and saves equipment space without affecting the normal operation of the equipment.
[0042] Furthermore, the lifting assembly 31 also includes a lifting member 315 and a moving block 316. The moving block 316 is sleeved on the outer peripheral wall of the lifting member 315 and fixedly connected to the fixed plate 311. The output shaft of the lifting member 315 abuts against the rear mold 22. One side of the moving block 316 is connected to the output shaft of the lifting member 315, and the other end is connected to the fixed plate 311. In use, the lifting member 315 drives the moving block 316 to rise, thereby driving the fixed plate 311 to rise. When the output shaft of the lifting member 315 abuts against the rear mold 22, it acts in the opposite direction to cause the moving block 316 to fall, thereby driving the fixed plate 311 to fall.
[0043] Furthermore, such as Figure 11 As shown, the first fixing plate 311 has a second through hole 3111. The outer peripheral wall of the main rotating shaft 33 is fitted with a second sliding member 332 adapted to the second through hole 3111. The second sliding member 332 is disposed in the second through hole 3111, and a fixing block 3321 is fitted on the outer peripheral wall of the second sliding member 332. The fixing block 3321 fixes the second sliding member 332 to the first fixing plate 311. In this embodiment, the second sliding member 332 is provided with a sliding groove, and a ball is provided in the sliding groove, so that the main rotating shaft 33 is rotatably connected in the second sliding member 332. By setting the second sliding member 332, the main rotating shaft 33 can be rotatably connected to the second sliding member 332 and move and rise synchronously with the first fixing plate 311.
[0044] Preferably, the lifting assembly 31 further includes a guide member 314, one end of which is connected to the second fixed plate 312, and the other end passes through the first fixed plate 311 and abuts against the first fixed plate 311. By setting the guide member 314, the first fixed plate 311 is provided with a stable guide during its movement toward or away from the second fixed plate 312, making the movement of the first fixed plate 311 more stable and precise.
[0045] The following is a detailed explanation of the working principle of this utility model;
[0046] The injection molding mechanism 2 closes the mold and performs injection molding to form a semi-finished product. The semi-finished product is integrally formed with the rotating component 34. The injection molding mechanism 2 opens the mold, and then the lifting component 31 drives the rotating component 34 to rise, causing the semi-finished product to completely detach from the injection molding mechanism 2. Subsequently, the first driving component 32 drives the main rotating shaft 33 to rotate, causing the rotating component 34 and the semi-finished product to rotate to the cooling position 12 for cooling. After cooling, the first driving component 32 drives the rotating component 34 and the semi-finished product to rotate to the second injection position 13 for secondary injection molding to form the product 5. 2. After mold opening, the rotating component 34 drives the product 5 to disengage from the injection molding mechanism 2 under the drive of the lifting component 31. The first driving component 32 drives the rotating component 34 to rotate the product 5 to the unloading position 14. Then, the ejection mechanism 4 includes an ejection plate 41 and a second driving component 42. In use, the output shaft of the second driving component 42 is connected to the ejection plate 41 to drive the ejection plate 41 to eject the product 5 located at the unloading position 14 and disengage from the rotating component 34, thereby realizing the first injection, cooling, second injection and unloading of the product 5 in sequence.
[0047] The innovation of this utility model lies in the integration of four workstations—first injection station, cooling station, second injection station, and unloading station—through a turret. Each rotation of the turret completes one process switch, realizing synchronous and continuous production of injection molding, cooling, secondary injection molding, and unloading. The groove of the ejector block is adapted to the shape of the mounting part, and it is precisely inserted into the mounting part during ejection. The product is smoothly ejected by the ejection force, avoiding manual contact or robot intervention.
