Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold core placement, and more specifically, to a transfer device for a mold core. Background Art
[0002] The core of a drainage pipe mold is a key component in the manufacture of drainage pipes and their accessories, forming the product's internal contours during the injection molding process. After injection molding, the core requires surface treatment. During the core processing process, the core is typically manually grasped and clamped onto a machining center. After core processing is complete, the core is manually removed from the machine. However, this manual loading and unloading method is not only labor-intensive and inefficient, but also poses certain safety risks.
[0003] Using a robot to replace manual loading and unloading can avoid the above problems. However, if a robot is used instead of manual loading and unloading, it is still necessary for the human to place the cores neatly on a pallet in the core storage area in advance, and then use a handling tool to move the pallet and the cores on the pallet to the vicinity of the robot so that the robot can efficiently and accurately grasp the cores. However, in the process of transporting the cores, the cores are prone to shifting or even overturning on the pallet. In this case, the robot will not be able to find the appropriate grasping position and grasping angle, which may result in failure to grasp the core or unstable grasping, and the inaccurate grasping position will also affect the accuracy of the subsequent processing of the core. In addition, the shifted or overturned cores may collide with each other, causing a certain degree of damage to the core. Utility Model Content
[0004] In response to the problem in the above-mentioned prior art that the cores are easily shifted or even overturned when the cores are placed on a tray, which is not conducive to the robot grasping the cores, the utility model provides a mold core transfer device, which can not only place multiple cores, but also prevent the cores from shifting or overturning, making it convenient for the robot to grasp the cores.
[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:
[0006] A transfer device for a mold core includes a base and multiple limit assemblies arranged on the base, each of the limit assemblies includes a support plate and a limit sleeve connected to the base, the support plate is located between the base and the limit sleeve, and the limit sleeve is provided with a limit cavity for the core to pass through.
[0007] When using the above technical solution, one end of the core is passed through the limiting cavity and then affixed to the support plate, so that the core stands upright on the support plate. In this way, a core is placed on each support plate, so that the cores are distributed in an orderly manner on the base. When the handling equipment is moving the base, the inner wall of the limiting cavity can limit the deviation or shaking of the core, thereby preventing the core from shifting or tipping over, which facilitates the robot arm to accurately and stably grasp the core.
[0008] Preferably, the limiting assembly further includes at least two sliding members for contacting the core, at least two of the sliding members are located on opposite sides of the axis of the limiting cavity, and the sliding members are connected to the limiting sleeve in a radially sliding manner along the limiting cavity. The distance between the sliding member and the outer circumferential surface of the core can be adjusted by sliding the sliding member, so that the sliding member can always contact the outer circumferential surface of the core, thereby improving the stability of the core during transportation and further reducing the deviation or shaking of the core. In addition, by providing the sliding member, the limiting requirements of cores of different diameters can also be met.
[0009] Preferably, a V-shaped groove is provided on one side of the sliding member close to the axis of the limiting through cavity. The V-shaped groove can increase the contact area between the sliding member and the core, thereby improving the limiting effect of the sliding member on the core.
[0010] It is understandable that the sliding member and the limiting cavity limit the movement of the entire core by limiting the offset and shaking of the middle part of the core. In this case, the bottom of the core will still shake to a certain extent. Preferably, the limiting assembly also includes a plurality of limiting rods for contacting the core, and the limiting rods are located between the base and the limiting sleeve; the support plate is provided with a plurality of guide cavities corresponding to the limiting rods, and the guide cavities extend along the radial direction of the limiting cavity, and the guide cavities are distributed around the axis of the limiting cavity; the limiting rods and the guide cavities are connected to each other in a radially sliding manner; the bottom of the limiting rod is provided with a counterweight block, and the counterweight block is located between the support plate and the base and abuts against the base. It is understandable that the counterweight block can not only keep the limiting rod in a stable upright state, but also increase the sliding resistance of the limiting rod, but not to the extent that the limiting rod cannot slide. The distance between the limit rod and the outer circumference of the core can be adjusted by sliding the limit rod, ensuring that the limit rod always contacts the outer circumference of the core. Unlike a sliding member, the limit rod can limit the deviation or shaking of the bottom of the core to a certain extent, thereby further improving the stability of the core.
[0011] When adjusting the position of the limit rod, manually sliding each limit rod separately is time-consuming and labor-intensive, and the adjustment efficiency is low. Preferably, the limit assembly also includes a drive turntable rotatably connected to the base, the drive turntable is located between the base and the support plate, and the rotation axis of the drive turntable coincides with the axis of the limit cavity. The drive turntable is provided with a plurality of arc-shaped cavities, and the plurality of arc-shaped cavities are distributed circumferentially with the rotation axis of the drive turntable as the array axis; the limit rods pass through the arc-shaped cavities one by one, and when the drive turntable rotates, the limit rods move radially along the drive turntable; the counterweight block is located between the drive turntable and the base. When the drive turntable rotates, the inner wall of the arc-shaped cavity exerts a thrust on the limit rod, and this thrust is in the radial direction of the drive turntable, that is, in the extension direction of the guide cavity, which can cause the limit rod to slide along the guide cavity. That is to say, when the position of the limit rod needs to be adjusted, it is only necessary to rotate the driving turntable to make the multiple limit rods slide synchronously, which can improve the efficiency of position adjustment of the limit rods.
[0012] When the support plate completely covers the top surface of the drive disc, it becomes difficult for a worker to maintain a stable grip on the drive disc, making it difficult to drive the drive disc. Preferably, a notch is provided on the edge of the support plate, exposing at least a portion of the top surface of the drive disc's edge. This notch exposes a portion of the drive disc's edge, allowing a worker to manually pinch this exposed portion to rotate the drive disc, thereby improving its efficiency.
[0013] Preferably, the limiting assembly further comprises a plurality of guide posts and a plurality of springs corresponding one-to-one with the guide posts, and the base is provided with a plurality of guide holes corresponding one-to-one with the guide posts; one end of the guide post is connected to the limiting sleeve, and the other end is inserted into the guide hole, and the guide post and the guide hole are slidably connected along the vertical direction; the spring sleeve is arranged outside the guide post, and one end of the spring is connected to the limiting sleeve, and the other end is connected to the support plate or the base. In the initial state, the limiting sleeve and the support plate maintain a certain distance under the elastic force of the spring. When the manipulator grasps the core, the manipulator can press down the limiting sleeve to expose more length of the core, so that the core and the manipulator have more contact area, which is conducive to the manipulator grasping the core steadily. When the limiting sleeve is pressed down by the manipulator, the spring is compressed and the guide post slides downward relative to the guide hole. After the manipulator removes the pressure on the limiting sleeve, the spring returns to its original state, thereby driving the limiting sleeve to rise to its initial position.
[0014] Preferably, the limiting assembly further includes at least two scissor-type connecting assemblies, each located on opposite sides of the limiting sleeve, with one connecting end of the scissor-type connecting assembly connected to the base and the other connecting end connected to the limiting sleeve. The scissor-type connecting assembly can ensure that the limiting sleeve remains balanced and stable during the lifting process, preventing the limiting sleeve from tilting and causing local scratches on the core.
[0015] Preferably, the base is provided with a plurality of positioning protrusions on the bottom. Before placing the core, the positioning protrusions can be inserted into the positioning holes on the external support platform to position the base on the external support platform. This prevents the base from moving during the core placement process, thereby affecting the core clamping efficiency, and prevents the base from moving during the core grasping process by the manipulator, thereby affecting the grasping accuracy of the manipulator.
[0016] Preferably, a proximity sensor is provided on at least one side of the base. In one preferred transport solution, the device can be transported using a forklift. During transport, the forklift's two forks can be supported on either side of the bottom of the base. The proximity sensor can detect the forklift's forks and confirm that they are in place, allowing the robot arm at the next workstation to prepare for action in advance.
[0017] Beneficial effects of the utility model:
[0018] 1. Set up multiple limit sleeves on the base, and use the limit cavity on the limit sleeve to limit the deviation or shaking of the core on the base, so as to prevent the core from deflecting or tipping over on the base. Multiple cores can be neatly placed on the base, making it convenient for the robot to accurately grasp the core.
[0019] 2. A sliding member is slidably provided on the limiting sleeve, and the sliding member can be kept in contact with the outer circumferential surface of the core by sliding the sliding member, thereby meeting the limiting requirements of cores of different specifications.
[0020] 3. Set a limit rod and a driving turntable. The limit rod can limit the shaking of the bottom of the core, thereby improving the stability of the core; an arc-shaped through cavity is set on the driving turntable, and the limit rods pass through the arc-shaped through cavity one by one. By rotating the driving turntable, multiple limit rods can be driven to slide synchronously, and the position of the limit rods can be efficiently adjusted.
[0021] 4. A spring is set between the limit sleeve and the base, and a scissor-type connection component is connected between the limit sleeve and the base, which can realize the stable lifting and lowering of the limit sleeve. By pressing down the limit sleeve, the core can be exposed to a longer length, so that the core and the manipulator have more contact area, which is conducive to the manipulator to grasp the core steadily.
[0022] 5. Multiple positioning protrusions are set on the bottom of the base to position the base on the external support platform; and a proximity sensor is set on the base to detect whether the forklift fork arm is in place, so that the robot arm at the next workstation can prepare for action in advance.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0033] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0034] Example 1
[0035] This embodiment is the first embodiment of a transfer device for a mold core, combined with Figure 1 and Figure 2 As shown, it includes a base 1 and six limiting components arranged on the base 1. The limiting components all include a support plate 2 and a limiting sleeve 3 connected to the base 1. The limiting sleeve 3 is located above the support plate 2. The limiting sleeve 3 is provided with a limiting cavity 301 for the core 12 to pass through.
[0036] Specifically, a circular boss 203 is provided on the top of the support plate 2 , and the axis of the circular boss 203 coincides with the axis of the limiting through cavity 301 . The circular boss 203 facilitates the positioning of the bottom of the core 12 .
[0037] The working principle or workflow of this embodiment is as follows: one end of the core 12 is passed through the limiting cavity 301 and then affixed to the support plate 2, so that the core 12 stands upright on the circular boss 203 of the support plate 2. In this manner, a core 12 is placed on each circular boss 203 of the support plate 2, so that the cores 12 are distributed in an orderly manner on the base 1. When the handling equipment is moving the base 1, the inner wall of the limiting cavity 301 can limit the deviation or shaking of the core 12, thereby preventing the core 12 from shifting or tipping over, which facilitates the robot arm to accurately and stably grasp the core 12.
[0038] The beneficial effects of this embodiment are as follows: a plurality of limit sleeves are arranged on the base, and the limit cavities on the limit sleeves are used to limit the displacement or shaking of the core on the base, thereby preventing the core from being displaced or tipping over on the base. A plurality of cores can be neatly placed on the base, making it convenient for the robot arm to accurately grasp the core.
[0039] Example 2
[0040] This embodiment is a second embodiment of a transfer device for a mold core. This embodiment is similar to the first embodiment, except that it is combined with Figures 1 to 3 As shown, the positioning assembly further includes two sliding members 4 for contacting the core 12. The two sliding members 4 are located on opposite sides of the axis of the positioning cavity 301 and are both slidably connected to the positioning sleeve 3 along the radial direction of the positioning cavity 301. The sliding members 4 can be adjusted to maintain contact with the outer circumferential surface of the core 12, thereby improving the stability of the core 12 during transportation and further reducing the deviation or shaking of the core 12. Furthermore, the provision of the sliding members 4 can also meet the positioning requirements of cores 12 of different diameters.
[0041] Furthermore, a V-shaped groove 401 is provided on one side of the sliding member 4 close to the axis of the limiting cavity 301. The V-shaped groove 401 can increase the contact area between the sliding member 4 and the core 12, thereby improving the limiting effect of the sliding member 4 on the core 12.
[0042] It can be understood that the sliding member 4 and the limiting cavity 301 limit the movement of the entire core 12 by limiting the deviation and shaking of the middle part of the core 12. In this case, the bottom of the core 12 will still shake to a certain extent. Furthermore, the limiting assembly also includes three limiting rods 5 for contacting the core 12, and the limiting rods 5 are located between the base 1 and the limiting sleeve 3; the support plate 2 is provided with three guide cavities 201 corresponding to the limiting rods 5, that is, one limiting rod 5 cooperates with one guide cavity 201; wherein the guide cavity 201 runs from the bottom of the support plate 2 to the top of the circular boss 203, and the guide cavity 201 extends along the radial direction of the limiting cavity 301, and the three guide cavities 201 are distributed circumferentially with the axis of the limiting cavity 301 as the array axis; the limiting rod 5 and the guide cavity 201 are connected to each other in a radial direction of the limiting cavity 301; a counterweight block 501 is provided at the bottom of the limiting rod 5, and the counterweight block 501 is located between the support plate 2 and the base 1 and abuts against the base 1. It can be understood that the counterweight block 501 not only keeps the limiting rod 5 in a stable upright state, but also increases the sliding resistance of the limiting rod 5 without making the limiting rod 5 unable to slide. The distance between the limiting rod 5 and the outer circumferential surface of the core 12 can be adjusted by sliding the limiting rod 5 so that the limiting rod 5 always contacts the outer circumferential surface of the core 12. Unlike the sliding member 4, the limiting rod 5 can limit the deviation or shaking of the bottom of the core 12 to a certain extent, thereby further improving the stability of the core 12.
[0043] When adjusting the position of the limit rod 5, if each limit rod 5 is slid manually, it will be time-consuming and labor-intensive, and the adjustment efficiency will be low. Figures 1 to 5As shown, the limiting assembly also includes a driving turntable 6 rotatably connected to the base 1. The driving turntable 6 is located between the base 1 and the support plate 2, and the rotation axis of the driving turntable 6 coincides with the axis of the limiting cavity 301. The driving turntable 6 is provided with three arcuate cavities 601, which are circumferentially distributed around the rotation axis of the driving turntable 6 and are shaped like circular arc segments. The limiting rods 5 pass through the arcuate cavities 601 one by one, that is, one limiting rod 5 passes through one arcuate cavity 601. When the driving turntable 6 rotates, the limiting rods 5 move radially along the driving turntable 6. The counterweight 501 is located between the driving turntable 6 and the base 1. When the driving turntable 6 rotates, the inner wall of the arcuate cavity 601 exerts a thrust on the limiting rod 5. This thrust is in the radial direction of the driving turntable 6, that is, in the extension direction of the guide cavity 201, which causes the limiting rod 5 to slide along the guide cavity 201. That is to say, when the position of the limiting rods 5 needs to be adjusted, it is only necessary to rotate the driving turntable 6 to make the three limiting rods 5 slide synchronously, which can improve the efficiency of position adjustment of the limiting rods 5.
[0044] When the support plate 2 completely covers the top surface of the drive disc 6, it is difficult for the operator to hold the drive disc 6 steadily, making it difficult to drive the drive disc 6. Furthermore, a notch 202 is provided on the edge of the support plate 2, exposing a portion of the top surface of the edge of the drive disc 6. With the notch 202, a portion of the edge of the drive disc 6 is exposed. The operator can manually pinch this exposed portion to rotate the drive disc 6, thereby improving the driving efficiency of the drive disc 6.
[0045] Other features, working principles and beneficial effects of this embodiment are consistent with those of embodiment 1.
[0046] Example 3
[0047] This embodiment is a third embodiment of a transfer device for a mold core. This embodiment is similar to the second embodiment, except that it is combined with Figure 1 、 Figure 2 、 Figure 4 and Figure 6As shown, the limiting assembly also includes four guide posts 7 and springs 8 corresponding to the four guide posts 7. Four guide holes 101 corresponding to the guide posts 7 are provided on the base 1, that is, one guide post 7 corresponds to one spring 8 and one guide hole 101. The top of the guide post 7 is connected to the limiting sleeve 3, and the bottom end is inserted into the guiding hole 101. The guide post 7 and the guiding hole 101 are slidably connected along the vertical direction. The spring 8 is sleeved on the outside of the guide post 7, and one end of the spring 8 is connected to the limiting sleeve 3, and the other end is connected to the support plate 2. In the initial state, the limiting sleeve 3 and the support plate 2 maintain a certain distance under the elastic force of the spring 8. When the manipulator grabs the core 12, the manipulator can press down the limiting sleeve 3 to expose more length of the core 12, so that the core 12 has more contact area with the manipulator, which is conducive to the manipulator to grasp the core 12 firmly. When the limit sleeve 3 is pressed down by the robot, the spring 8 is compressed and the guide column 7 slides downward relative to the guide hole 101. After the robot removes the pressure on the limit sleeve 3, the spring 8 returns to its original state, thereby driving the limit sleeve 3 to rise to its initial position.
[0048] Furthermore, the limit assembly also includes two Figure 7 The illustrated scissor-type connection assemblies 9 are positioned on opposite sides of the stop sleeve 3. The top connection end of each scissor-type connection assembly 9 is connected to the base 1, while the bottom connection end is connected to the stop sleeve 3. Since these scissor-type connection assemblies 9 are conventional, their specific structure and operation will not be further described in this embodiment. These scissor-type connection assemblies 9 ensure balance and stability during the lifting and lowering of the stop sleeve 3, preventing the stop sleeve 3 from tilting and causing local scratches on the core 12.
[0049] Furthermore, four positioning protrusions 10 are provided on the bottom of the base 1. Before placing the core 12, the positioning protrusions 10 can be inserted into the positioning holes on the external support platform to position the base 1 on the external support platform. This prevents the base 1 from moving while the worker is placing the core 12, which would affect the clamping efficiency of the core 12, and also prevents the base 1 from moving while the robot is grasping the core 12, which would affect the grasping accuracy of the robot.
[0050] Furthermore, a proximity sensor 11 is provided on one side of the base 1. In one preferred transport solution, the device can be transported using a forklift. During transport, the forklift's two forks can be supported on either side of the bottom of the base 1. The proximity sensor 11 can detect the forklift's forks and confirm that they are in place, allowing the robot and equipment at the next workstation to prepare for action in advance.
[0051] Other features, working principles and beneficial effects of this embodiment are consistent with those of Example 2.

In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description, and it is not necessary and impossible to enumerate all implementation methods here.
