Description

Technical Field

[0001] This utility model belongs to the field of automated equipment processing, and specifically relates to an injection molding pusher with a positioning avoidance structure. Background Technology

[0002] In actual production, injection molding technology, as the core process of plastic product processing, places higher demands on the multi-station collaborative capabilities and automation level of equipment in fields such as two-color injection molding and insert molding. Traditional two-color injection molding equipment mostly adopts single-station molds or split turntable structures, requiring multiple mold openings, jig transfers, and manual intervention to complete two-color injection molding and unloading. This presents the following technical bottlenecks: In traditional processes, after the first injection, manual or robotic arms are required to transfer the semi-finished product to the second injection station. Cooling and molding processes cannot be carried out simultaneously, extending the production cycle. Furthermore, reliance on manual demolding or simple ejection mechanisms can easily cause product damage. Moreover, the mechanical structures of the injection and unloading mechanisms are prone to interference due to unreasonable spatial layout. For example, the lifting movement of the injection mechanism may limit the forming range of the pusher mechanism, resulting in bulky equipment or restricted pusher action, affecting the unloading of injection molded products and leading to low production efficiency. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] This invention provides an injection molding ejector device with a clearance structure, which aims to solve the problem of interference that occurs when secondary injection molding requires multiple mold openings, jig transfers, and material unloading.

[0005] (2) Technical solution

[0006] This utility model provides an injection molding ejector device with a clearance structure, including a frame, on which is provided a turret that can be raised, lowered, and rotated, a first module, and a second module that is raised and lowered in cooperation with the first module. An injection position one, an injection position two, and an ejector position are sequentially arranged around the turret between the first module and the second module. Each injection position one and injection position two contains an injection module, and each injection module contains an injection cavity. The turret is provided with several fixtures that cooperate with the injection positions one, two, and the ejector position.

[0007] The frame is equipped with a pushing mechanism corresponding to the pushing position. The pushing mechanism includes a driving component and a pushing assembly. The pushing assembly includes a pushing plate, a connecting plate parallel to the pushing plate, and two parallel guide pillars connecting the pushing plate and the connecting plate. The pushing plate, the connecting plate, the first guide pillar, and the second guide pillar form a clearance area. The turret is located in the clearance area. The output shaft of the driving component is connected to the connecting plate to drive the pushing assembly to move and push materials.

[0008] Furthermore, the pusher assembly also includes a mounting base, which is disposed between the pusher plate and the connecting plate, and the first guide post and the second guide post pass through the mounting base.

[0009] Furthermore, the pusher plate is provided with a groove that is compatible with the fixture.

[0010] Furthermore, a transition position is provided between the first module and the second module. The transition position is located between the first injection molding position and the second injection molding position, and the transition position is located on the opposite side of the pusher position.

[0011] Furthermore, the rotating disk is provided with four fixtures, which correspond to the first injection position, the transition position, the second injection position, and the push position, respectively.

[0012] Furthermore, the fixture is provided with a plurality of extension rods, and the injection molding module is provided with a plurality of injection cavities, each corresponding to one of the extension rods.

[0013] Furthermore, the turret also includes a main shaft, a rotating component that drives the main shaft to rotate, and a rotating disk coaxially connected to the main shaft, wherein the fixture is fixedly connected to the rotating disk.

[0014] Furthermore, the turret also includes a lifting assembly that drives the main rotating shaft to rise and fall. The lifting assembly includes a moving plate with a lifting component on the moving plate, and the output shaft of the lifting component is fixedly connected to the second module.

[0015] Furthermore, the lifting assembly also includes a limiting plate, which is arranged parallel to and corresponding to the moving plate. The limiting plate is provided with a connecting column, which passes through the moving plate and is fixedly connected to the second module.

[0016] Furthermore, there are two lifting components, which are symmetrically arranged on the moving plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By forming a closed clearance zone with the guide column one, guide column two, pusher plate and connecting plate, the main shaft of the turret can pass through it, realizing complete spatial clearance between the pusher action and the turret rotation / lifting.

[0019] 2. The circular layout of injection station 1, transition station, injection station 2, and pusher station enables precise switching of workstations via a turret.

Detailed Implementation

[0033] 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.

[0034] like Figure 1-3 As shown, this utility model provides an injection molding pusher device with a clearance structure, including a frame 1. The frame 1 is provided with a first module 3 and a second module 4 that can be opened and closed vertically. The frame 1 is also provided with a turret 2 that can be raised, lowered, and rotated. The turret 2 includes a main rotating shaft 22, a rotating component 21 that drives the main rotating shaft 22 to rotate, a lifting component 23 that drives the main rotating shaft 22 to rise and fall, a rotating disk 24 coaxially connected to the main rotating shaft 22, and a fixture 25 connected to the rotating disk 24.

[0035] In use, the turret 2 is sequentially inserted into the first module 3 and the second module 4 under the action of the lifting component 23, and the fixture 25 is disposed between the first module 3 and the second module 4;

[0036] An injection molding station 11, an injection molding station 23, and a pusher station 14 are sequentially arranged around the turret 2 between the first module 3 and the second module 4. Each injection molding station 11 and injection molding station 23 contains an injection molding module 15. Each injection molding module 15 includes a fixed mold 151 and a moving mold 152. The fixed mold 151 is disposed on the second module 4, and the moving mold 152 is disposed on the first module 3. The fixed mold 151 and the moving mold 152 close together under the action of a driving component to form an injection cavity 16. During mold closing, at least a portion of the fixture 25 extends through the injection molding module 15 into the injection cavity 16 and is integrally formed with the product 6. The output shaft of the rotating component 21 rotates, driving the fixture 25 to rotate at the injection molding station 15. 11. Injection position 13 and ejector position 14: After the fixture 25 is integrally formed with the product 6, the mold is opened. The rotating part 21 of the fixture 25 rotates to reach the ejector position 14 after the fixture 25 is integrally formed with the product 6. The frame 1 is also provided with an ejector mechanism 5 corresponding to the ejector position 14. The ejector mechanism 5 includes a drive component 51 and an ejector assembly 52. ​​The output shaft of the drive component 51 is connected to the ejector assembly 52 to drive the ejector assembly 52 to move and eject material. In use, the ejector assembly 52, under the action of the drive component 51, removes the product 6, which is integrally formed with the fixture 25, from the ejector position 14 to obtain the product 6.

[0037] Preferably, the rotating component 21 is a motor in this embodiment. In this embodiment, the driving component 51 is a motor, but it can also be a cylinder or a lead screw.

[0038] Specifically, such as Figure 3-5As shown, a transition position 12 is also provided between the first module 3 and the second module 4. The transition position 12 is located between the first injection position 11 and the second injection position 13, and the transition position 12 is set on the opposite side of the pusher position 14. In use, the rotating component 21 drives the rotating disk 24 to rotate sequentially between the first injection position 11, the transition position 12, the second injection position 13, and the pusher position 14 to perform a production process of one injection, cooling after the first injection, a second injection, and unloading. Specifically, the rotating component 21 drives the rotating disk 24 to rotate. The fixture 25 is located at the injection position 11. The lifting assembly 23 drives the fixture 25 to the fixed mold 151. The fixed mold 151 and the moving mold 152 are closed for injection molding to form a one-time injection molded product. The fixed mold 151 and the moving mold 152 are separated by the driving component. The lifting assembly 23 raises the fixture 25 to separate it from the fixed mold 151, so that the one-time injection molded product integrally formed with the fixture 25 is located between the fixed mold 151 and the moving mold 152. Subsequently, the rotating component 21 rotates the one-time injection molded product to the transition position. Position 12 is cooled, and then the rotating component 21 rotates the first-injection molded product to injection position 13, which is located between the second set of fixed mold 151 and moving mold 152. The lifting component 23 lowers the first-injection molded product, which is integrally formed with the fixture 25, into the fixed mold 151. The fixed mold 151 and the moving mold 152 close for secondary injection molding to form the secondary injection molded product 6. Then the mold is opened, and the lifting component 23 lifts the product 6, which is integrally formed with the fixture 25, and removes it from the fixed mold 151. The rotating component 21 then fixes the product... The fixture 25 of product 6 rotates to the push position 14 for unloading, achieving continuous automatic production. By setting the transition position 12, the finished product after the first injection is fully cooled before entering the second injection position 13 for a second injection, resulting in better molding. The rotating disk 24 completes multiple steps for one product 6 with one rotation, realizing the simultaneous operation of four processes: first injection molding, cooling and shaping, second injection, and ejection unloading. This improves the production cycle, greatly increases production efficiency, optimizes space utilization, and enables continuous production.

[0039] Furthermore, such as Figure 5 and Figure 6 As shown, the rotating disk 24 is equipped with four fixtures 25, which correspond to injection position 11, transition position 12, injection position 23 and push position 14 respectively. This allows for simultaneous operation of multiple stations. Injection position 11 is performing a first injection, while transition position 12 can cool the finished product after the first injection. Injection position 23 is performing a second injection, while push position 14 completes the unloading operation. This multi-station parallel operation significantly shortens the production cycle and improves the overall production efficiency.

[0040] Preferably, such as Figure 6As shown, the fixture 25 is provided with a plurality of extension rods 26, and the injection molding module 15 is provided with a plurality of injection cavities 16, which are respectively arranged in a one-to-one correspondence with the extension rods 26. This allows for the simultaneous injection molding of multiple products 6, significantly improving production efficiency. By simultaneously injection molding multiple products 6, the production time of a single product 6 is reduced, thereby shortening the overall production cycle. Each extension rod 26 corresponds to one injection cavity 16, ensuring uniform distribution of injection pressure and temperature, thereby improving the molding quality of each product 6. Through precise correspondence, defects such as bubbles and shrinkage marks caused by uneven injection pressure or uneven material distribution can be reduced.

[0041] It should be noted that the extension rod 26 is made of a high-temperature resistant and wear-resistant material. During the injection molding process, the extension rod 26 and the product 6 are integrally molded, which needs to take into account temperature changes and mechanical stress, improve positioning accuracy, enhance system rigidity, reduce vibration and noise, and improve load capacity.

[0042] It should be noted that, in order to ensure that the first module 3 and the second module 4 fit tightly together during mold closing and to avoid flash or cavity displacement due to pressure fluctuations, in this embodiment, the mold closing of the first module 3 and the second module 4 is carried out by hydraulic drive. Through the synchronous operation of the two injection ports and the cyclic operation of the turret 2 station, the production capacity per unit time is increased.

[0043] Specifically, such as Figure 7 As shown, the lifting assembly 23 includes a movable plate 231, on which a lifting component 232 is provided. The output shaft of the lifting component 232 is fixedly connected to the second module 4. In use, the lifting component 232 is fixed to the movable plate 231. When injection molding is required, the output shaft of the lifting component 232 moves upward, and the fixed connection between the lifting component 232 and the second module 4 acts in the opposite direction on the movable plate 231, causing the movable plate 231 to descend. When the product 6 needs to be removed from the fixed mold 151, the lifting component 232 drives the movable plate 231 to move upward.

[0044] Furthermore, in order to ensure that the lifting component 232 drives the moving plate 231 to move smoothly, there are two lifting components 232, which are symmetrically arranged on the moving plate 231 to ensure the uniform distribution of force during the lifting process, avoid the moving plate 231 tilting or becoming unstable due to unilateral force, reduce the vibration generated during the lifting process, and improve the stability of the equipment operation.

[0045] Furthermore, such as Figure 8As shown, to achieve the rotation and lifting of the turret 2, the lifting assembly 23 further includes a bracket 233. One end of the bracket 233 is connected to the moving plate 231, and the other end is fixedly connected to the rotating component 21. The main rotating shaft 22 passes through the bracket 233 and is fixedly connected to the output shaft of the rotating component 21. The main rotating shaft 22 is rotatably connected to the bracket 233. The bracket 233 is connected to the moving plate 231 and rises and falls with the moving plate 231, thereby driving the main rotating shaft 22 to rise and fall, so that the fixture... The fixture 25 is movably connected within the space between the fixed mold 151 and the moving mold 152. The outer shell of the rotating component 21 is fixed to the bracket 233. The output shaft of the rotating component 21 is fixedly connected to the main rotating shaft 22, which drives the main rotating shaft 22 to rotate, thereby driving the fixture 25 to rotate between the injection position 11, the transition position 12, the injection position 23, and the ejector position 14. Through the connection of the bracket 233, the lifting and rotating actions of the main rotating shaft 22 can be controlled more precisely, ensuring the precise movement of the fixture 25 between different positions.

[0046] Furthermore, such as Figure 9-10 As shown, the lifting assembly 23 also includes a limiting plate 234, which is parallel to and corresponding to the moving plate 231. The limiting plate 234 is provided with a connecting post 235, which passes through the moving plate 231 and is fixedly connected to the second module 4. By setting the connecting post 235, the limiting plate 234 is fixedly connected to the lower part of the second module 4, and the limiting plate 234 is located below the moving plate 231. By setting the connecting post 235, the moving plate 231 provides guidance and stability when it approaches or moves away from the limiting plate 234, preventing the moving plate 231 from deviating or shaking during the lifting process, and ensuring that the fixture 25 accurately reaches the injection cavity 16 during injection molding.

[0047] Specifically, such as Figure 11As shown, the pushing assembly 52 includes a pushing plate 521, a connecting plate 522 parallel to and corresponding to the pushing plate 521, and two parallel guide posts 523 and 524 connecting the pushing plate 521 and the connecting plate 522. The pushing plate 521, the connecting plate 522, the first guide post 523, and the second guide post 524 form a clearance area 525. The main rotating shaft 22 is disposed within the clearance area 525, so that when the pushing plate 521 pushes out the product 6 under the action of the first driving member 51, it avoids colliding with the main rotating shaft 22. This achieves complete spatial avoidance between the pushing action and the rotation and lifting of the turret 2. In use, the output shaft of the first drive component 51 is fixedly connected to the connecting plate 522 to drive the connecting plate 522 to move, thereby driving the first guide post 523, the second guide post 524 and the pusher plate 521 to move. When the product 6 moves to the pusher plate 521, the first drive component 51 drives the pusher plate 521 to push out, disengaging the product 6 from the fixture 25. Subsequently, the first drive component 51 drives the pusher plate 521 to retract and wait for the product 6 to arrive at the next pushing action.

[0048] Furthermore, the pusher assembly 52 also includes a mounting base 526, which is disposed between the pusher plate 521 and the connecting plate 522. The mounting base 526 is fixedly mounted on the second module 4. The main rotating shaft 22 separates the mounting base 526 and the connecting plate 522 on both sides of the main rotating shaft 22. The first guide post 523 and the second guide post 524 pass through the mounting base 526, and their two ends are fixedly connected to the pusher plate 521 and the connecting plate 522, respectively. By setting the mounting base 526... 26, so that the first guide post 523 and the second guide post 524 remain stable during movement to prevent deviation or swaying, thereby ensuring smooth movement of the pusher plate 521. This allows the fixture 25 to correspond with the pusher plate 521 and better push out the product 6. At the same time, the mounting base 526 is located on one side of the pusher plate 521, so that when the first drive component 51 drives the pusher plate 521 to return to its original position, it avoids excessive return, which could cause the pusher plate 521 to collide with the main rotating shaft 22, thus ensuring the safe operation of the equipment.

[0049] Preferably, such as Figure 11-12 As shown, the pusher plate 521 is provided with a groove 5211 that is adapted to the extension rod 26. In use, the extension rod 26 reaches the groove 5211 and matches the groove 5211. By designing the groove 5211, the positioning is ensured to be accurate, the deviation is reduced, and the extension rod 26 is easy to disengage from the product 6. This ensures that the pusher only contacts the molded product 6 and avoids mechanical damage to the extension rod. This design reduces the separation of the product 6 from the extension rod 26 during the ejection process.

[0050] The following is a detailed explanation of the working principle of this utility model;

[0051] The rotating component 21 drives the fixture 25 to be positioned at injection position 11. The lifting component 23 drives the fixture 25 to the fixed mold 151. The fixed mold 151 and the moving mold 152 are closed for injection molding to form a one-time injection molded product. The driving component separates the fixed mold 151 from the moving mold 152. The lifting component 23 raises the fixture 25 to separate it from the fixed mold 151, so that the one-time injection molded product integrally formed with the fixture 25 is located between the fixed mold 151 and the moving mold 152. Subsequently, the rotating component 21 rotates the one-time injection molded product to the transition position 12 for cooling. Then, the rotating component 21 rotates the one-time injection molded product to injection position 13, which is located between the second set of fixed mold 151 and moving mold 152. The part 23 is lowered and integrally formed with the fixture 25 into the fixed mold 151. The fixed mold 151 and the moving mold 152 are closed for secondary injection molding to form the secondary injection molded product 6. Then the mold is opened, and the lifting component 23 lifts the product 6 integrally formed with the fixture 25 and separates it from the fixed mold 151. The rotating component 21 rotates the fixture 25, which is fixed with the product 6, to the push position 14 for unloading. The integrally formed product 6 and the fixture 25 move to the groove 5211. The driving component 51 drives the push plate 521 to push out and push out the product 6, so that the product 6 is separated from the extension rod 26. The cycle is repeated to achieve a continuous automatic production and unloading effect.

[0052] The innovation of this utility model lies in the fact that the guide pillar one, guide pillar two, pusher plate and connecting plate form a closed avoidance zone, through which the main shaft of the turret can pass, realizing complete spatial avoidance between the pusher action and the rotation / lifting of the turret; the circumferential layout of injection position one, transition position, injection position two and pusher position, through the turret, realizes precise switching of work positions, and the four work positions simultaneously execute the continuous process of one injection → cooling → secondary injection → unloading, breaking through the traditional serial production mode of injection molding machines and improving work efficiency.

This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
