Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment, and in particular to an injection molding equipment capable of continuous operation. Background Technology

[0002] As the core equipment for mass production of plastic products, the efficiency of mold injection equipment directly affects the production cycle and cost control. In the existing technology, conventional injection molding machines generally adopt a single-station design, that is, molten plastic is injected into a single mold through the injection mechanism, and the mold that has been completed is removed by manpower and replaced with the mold to be injected for secondary operation.

[0003] This type of process has significant drawbacks. The manual loading and unloading operation is highly dependent on the operator's skill and physical strength. Moving molds requires a lot of physical strength, and fatigue will reduce the efficiency of mold replacement during continuous operation, making it impossible to integrate into automated production lines. Utility Model Content

[0004] The purpose of this invention is to provide a continuously operating injection molding device, in which a turntable sequentially drives multiple molds into the working area for injection molding, and the molds that have completed injection molding are then taken out of the working area.

[0005] The technical solution adopted by the continuously operating injection molding equipment disclosed in this utility model is:

[0006] The device includes two robotic arms, a worktable, an injection molding mechanism, a turntable, and a drive mechanism. The worktable is fixedly connected to a lifting mechanism. The worktable is sequentially provided with a loading area, a working area, and a unloading area. The two robotic arms are located near the loading and unloading areas, respectively. A pad is provided in the working area. A first slide is passed through the worktable, and a connecting ring is rotatably connected to the first slide. The injection molding mechanism is connected to the lifting mechanism and is located above the working area. The turntable is axially slidably connected to the connecting ring and is located above the pad. A spring is sleeved on the outer side of the connecting ring, with both ends of the spring contacting the connecting ring and the turntable, respectively. The turntable has multiple storage areas, and a first gear is fixedly connected to the bottom of the turntable. The drive mechanism is connected to the first gear.

[0007] As a preferred embodiment, the connecting ring is provided with a plurality of spaced-apart fasteners, one end of which passes through the connecting ring and is fixedly connected to the turntable, and the middle part of which is slidably connected to the connecting ring.

[0008] As a preferred embodiment, the storage area is equipped with an anti-slip mat.

[0009] As a preferred embodiment, the drive mechanism includes a motor, which is fixedly connected to the worktable. The output shaft of the motor is fixedly connected to a second gear, which meshes with the first gear.

[0010] As a preferred embodiment, the worktable has two second slides running through it. The lifting mechanism includes a first cylinder and a lifting platform. The first cylinder is fixedly connected to the worktable, and the output shaft of the first cylinder is fixedly connected to the lifting platform. Three parallel first guide rods are fixedly connected to the lifting platform. One end of each of the three first guide rods passes through the first slide and the two second slides respectively and is slidably connected to them. The injection molding mechanism is connected to one end of the first guide rods, and the three first guide rods surround the outside of the working area.

[0011] As a preferred embodiment, the injection molding mechanism includes a support platform and an injection device. The support platform is fixedly connected to one end of the first guide rod, and the injection device is placed on top of the support platform, with the injection port of the injection device penetrating through the support platform.

[0012] As a preferred embodiment, two parallel second optical rods are fixedly connected to the support platform, the injection molding device is slidably connected to the second optical rods, and two second cylinders are fixedly connected to the support platform, with the output shaft of the second cylinders fixedly connected to the injection molding device.

[0013] The beneficial effects of the continuously operating injection molding equipment disclosed in this utility model are:

[0014] The drive mechanism drives the turntable to perform indexing rotation, so that each placement area enters the loading area, working area and unloading area in sequence. When the placement area is positioned in the working area, the turntable pauses its rotation for a certain period of time.

[0015] During the loading stage, one of the robotic arms grabs the mold to be injected and precisely places it into the storage area within the loading zone. After indexing and rotating, the mold is moved to the working area. The lifting mechanism drives the injection mechanism to lower and press down on the mold. The mold pushes the turntable to slide down on the connecting ring and compress the spring, so that the bottom of the turntable touches the top of the pad block. The pad block supports the turntable and works with the injection mechanism to clamp the mold and inject molten plastic. After injection is completed, the lifting mechanism drives the injection mechanism to rise. The spring pushes the turntable to slide up and return to its original position on the connecting ring. At the same time, the turntable continues to index and rotate to move the mold to the unloading zone, where another robotic arm grabs the mold that has completed injection and removes it from the unloading zone.

[0016] By coordinating the operation of two robotic arms with the timing of indexing and positioning, a closed-loop production system is constructed to achieve seamless integration of automated loading and unloading with injection molding, thereby improving the efficiency of continuous production of this equipment.

[0023] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0024] Please refer to Figures 1-4 .

[0025] The present invention discloses a continuously operating injection molding equipment, including a worktable 1, two robotic arms, a turntable 2, and an injection molding mechanism 6.

[0026] The bottom of the workbench 1 is equipped with a support bracket, which is set up in the site. The workbench 1 is provided with a loading area, a working area and a unloading area in sequence. Two robotic arms are located near the loading area and the unloading area respectively. The working area is provided with pad blocks 11.

[0027] Turntable 2 is rotatably connected to worktable 1, and turntable 2 is located on top of worktable 1;

[0028] Furthermore, a first slide block 12 extends through the worktable 1, and a bearing 121 is fitted on the outer side of the first slide block 12; a first step is provided on the outer side of the first slide block 12, and the first step locks the inner ring of the bearing 121. The first step can prevent the bearing 121 from slipping off the outer side of the first slide block 12.

[0029] Furthermore, a connecting ring 122 is rotatably connected to the first slide block 12; a second step is provided on the inner wall of the connecting ring 122, the second step is engaged with the outer side of the bearing 121, the second step can prevent the connecting ring 122 from slipping off the outer ring of the bearing 121, so that the connecting ring 122 is rotatably connected to the first slide block 12 through the bearing 121; the connecting ring 122 is axially slidably connected to the turntable 2, a spring 123 is sleeved on the outer side of the connecting ring 122, a third step is provided on the outer side of the connecting ring 122, and the two ends of the spring 123 respectively abut against the third step of the connecting ring 122 and the bottom of the turntable 2;

[0030] Furthermore, the connecting ring 122 is provided with a plurality of spaced-apart fixing members 124. One end of the fixing member 124 passes through the connecting ring 122 and is fixedly connected to the bottom of the turntable 2. The middle part of the fixing member 124 is slidably connected to the connecting ring 122. The turntable 2 is slidably connected to the connecting ring 122 through the fixing member 124. The top of the pad 11 is higher than the top of the connecting ring 122. In this embodiment, it is preferable that the top of the pad 11 is 3 mm away from the bottom of the turntable 2, so that the turntable 2 will not contact the pad 11 when rotating. The turntable 2 only needs to be lowered by 3 mm for the pad 11 to support the turntable 2.

[0031] Furthermore, a first gear 21 is fixedly connected to the bottom of the turntable 2. In this embodiment, the first gear 21 is preferably a hollow annular structure, and the connecting ring 122 is located inside the first gear 21. The first gear 21 and the connecting ring 122 are coaxial.

[0032] Furthermore, the top of the turntable 2 is provided with multiple storage areas. In this embodiment, it is preferred that there are three storage areas, which are arranged around the center of the turntable 2 at intervals, and the angle between two adjacent storage areas is 120°. Anti-slip mats 22 are provided in the storage areas and are fixedly connected to the top of the turntable 2. In this embodiment, it is preferred that the anti-slip mats 22 are made of rubber, which can increase the friction between the bottom of the mold and the top of the anti-slip mats 22 and prevent the mold from shifting when the turntable 2 rotates.

[0033] The drive mechanism 4 is connected to the first gear 21. The drive mechanism 4 includes a motor 41. The motor 41 is fixedly connected to the bottom of the worktable 1. The output shaft of the motor 41 passes through the worktable 1. The output shaft of the motor 41 is fixedly connected to a second gear 42. The second gear 42 meshes with the first gear 21.

[0034] The output shaft of motor 41 drives the first gear 21 and turntable 2 to rotate through the second gear 42, thereby causing the turntable 2 to drive the three storage areas to enter the loading area, the working area and the unloading area in sequence.

[0035] Please refer to Figure 1 , Figure 5 and Figure 6 .

[0036] The workbench 1 is fixedly connected to the lifting mechanism 5, and the injection molding mechanism 6 is connected to the lifting mechanism 5;

[0037] Furthermore, two second slides 13 pass through the workbench 1, and the lifting mechanism 5 includes a first cylinder 51 and a lifting platform 52; the first cylinder 51 is fixedly connected to the bottom of the workbench 1, and the output shaft of the first cylinder 51 is fixedly connected to the lifting platform 52. Three parallel first guide rods 521 are fixedly connected to the lifting platform 52. One end of each of the three first guide rods 521 passes through the first slide 12 and the two second slides 13 respectively, and the middle part of each of the three first guide rods 521 is slidably connected to the first slide 12 and the two second slides 13 respectively. The first guide rods 521 on the first slide 12 are coaxial with the turntable 2, and the first guide rods 521 on the two second slides 13 are located outside the turntable 2. The three first guide rods 521 surround the outside of the working area.

[0038] Furthermore, the injection molding mechanism 6 is connected to one end of the first guide rod 521. The injection molding mechanism 6 is located above the working area. The injection molding mechanism 6 includes a support platform 61 and an injection device 62. The support platform 61 is fixedly connected to one end of the first guide rod 521. The support platform 61 and the lifting platform 52 are parallel to each other. The injection device 62 is placed on top of the support platform 61, and the injection port of the injection device 62 passes through the support platform 61.

[0039] Furthermore, two parallel second guide rods 611 are fixedly connected to the support platform 61, the injection molding device 62 is slidably connected to the second guide rods 611, and two second cylinders 612 are fixedly connected to the support platform 61. The output shaft of the second cylinder 612 is fixedly connected to the injection molding device 62, and the output shaft of the second cylinder 612 is parallel to the second guide rods 611.

[0040] The output shaft of the first cylinder 51 pushes the lifting platform 52 down, and the first guide rod 521 slides down on the worktable 1, thereby pulling the support platform 61 down to contact the mold in the working area; the output shaft of the second cylinder 612 pulls the injection device 62 to slide down on the second guide rod 611, so that the injection port of the injection device 62 approaches and contacts the mold feed port in the working area.

[0041] Please refer to Figures 1-6 .

[0042] When this device is in operation:

[0043] The drive mechanism 4 drives the turntable 2 to perform indexing rotation, so that each placement area enters the loading area, working area and unloading area in sequence. When the placement area is positioned in the working area, the turntable 2 pauses rotation for a certain period of time to provide the injection molding device 62 with working time to inject molten plastic into the mold.

[0044] During the loading stage, the mold to be injected is held by one of the robotic arms and precisely placed on the storage area located in the loading area, with the bottom of the mold in contact with the top of the anti-slip pad 22;

[0045] During the operation phase, the drive mechanism 4 drives the turntable 2 to rotate in an indexing motion, allowing the mold to be injected into the operation area. At this time, the storage area in the loading area is empty. One of the robotic arms then places another mold to be injected. The output shaft of the first cylinder 51 pushes the first guide rod 521 and the support platform 61 to descend synchronously through the lifting platform 52, so that the support platform 61 touches the top of the mold. The support platform 61 continues to push the mold down, and the mold presses down and pushes the turntable 2 to slide down on the connecting ring 122. At the same time, the spring 123 is compressed, so that the bottom of the turntable 2 touches the top of the pad block 11. The pad block 11 supports the turntable 2 and works with the injection mechanism 6 to clamp the mold, so that the support platform 61 applies pressure to the turntable. The downward pressure of cylinder 2 is supported by pad 11 and worktable 1, which avoids damaging bearing 121 by the downward pressure applied by worktable 61 without reducing the clamping force of turntable 2 and support table 61 in holding the mold; the output shaft of the second cylinder 612 pulls the injection device 62 to slide down, so that the injection port of the injection device 62 approaches and contacts the mold feed port, allowing the injection device 62 to inject molten plastic; after injection is completed, the output shaft of the second cylinder 612 pushes the injection device 62 to slide up, so that the injection port of the injection device 62 moves away from the mold feed port; the output shaft of the first cylinder 51 pulls the first guide rod 521 and support table 61 to rise synchronously through the lifting platform 52, so that the support table 61 moves away from the mold;

[0046] During the unloading stage, the drive mechanism 4 drives the turntable 2 to rotate again, and the mold that has completed injection is sent into the unloading area. Another mold to be injected enters the working area, and the above injection operation steps are repeated. Another robotic arm grabs the mold that has completed injection and moves it away from the unloading area. At this time, the storage area in the unloading area is in a controlled state. The drive mechanism 4 drives the turntable 2 to rotate again, and the empty storage area enters the loading area.

[0047] This utility model provides an injection molding equipment that can operate continuously. The drive mechanism drives the turntable to perform indexing rotation, so that each placement area enters the loading area, the working area and the unloading area in sequence. When the placement area is positioned in the working area, the turntable pauses its rotation for a certain period of time.

[0048] During the loading stage, one of the robotic arms grabs the mold to be injected and precisely places it into the storage area within the loading zone. After indexing and rotating, the mold is moved to the working area. The lifting mechanism drives the injection mechanism to lower and press down on the mold. The mold pushes the turntable to slide down on the connecting ring and compress the spring, so that the bottom of the turntable touches the top of the pad block. The pad block supports the turntable and works with the injection mechanism to clamp the mold and inject molten plastic. After injection is completed, the lifting mechanism drives the injection mechanism to rise. The spring pushes the turntable to slide up and return to its original position on the connecting ring. At the same time, the turntable continues to index and rotate to move the mold to the unloading zone, where another robotic arm grabs the mold that has completed injection and removes it from the unloading zone.

[0049] By coordinating the operation of two robotic arms with the timing of indexing and positioning, a closed-loop production system is constructed to achieve seamless integration of automated loading and unloading with injection molding, thereby improving the efficiency of continuous production of this equipment.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
