[0036] Embodiment 1

[0037] As Figures 1 to 3 shown in the first embodiment of an automatic core-removing device of the present utility model, it includes a frame 1 for installing and fixing various mechanisms; a slide rail mechanism 2 installed on the frame 1; a clamping mechanism 3 for fixing the main sprue, installed on the frame 1; a fixing mechanism 4 for fixing the core, slidably connected to the slide rail mechanism 2 and movable under the clamping mechanism 3; a rotating mechanism 5 for driving the product to rotate relative to the core, slidably connected to the slide rail mechanism 2; and a driving mechanism 6 connected to the fixing mechanism 4 and the rotating mechanism 5 and used to drive the two to move respectively, installed on the frame 1.

[0038] As an embodiment of the present utility model, the core is fixed by the fixing mechanism 4, the main sprue is fixed by the clamping mechanism 3, the driving mechanism 6 drives the fixing mechanism 4 and the rotating mechanism 5 to move on the slide rail mechanism 2, and the rotating mechanism 5 drives the product to rotate relative to the core, thereby achieving the effect of completing the removal of the threaded core and automatically separating the product from the sprue, realizing automated operation, improving production efficiency, and reducing the labor intensity of workers.

[0039] The rotating mechanism 5 of the present utility model includes a motor 54, a driving member 55, a plurality of driven members 56, a plurality of clamping jaws 57, and a transmission shaft 58. The driving member 55 is connected to the output shaft of the motor 54. The driven members 56 and the clamping jaws 57 are both installed on the transmission shaft 58. The driving member 55 meshes with the plurality of driven members 56. In this embodiment, both the driving member 55 and the driven members 56 are gears. The driving member 55 meshes with two driven members 56. The gear meshing transmission has high efficiency and can effectively transmit power from the output shaft to the transmission shaft 58. Moreover, the gear transmission can provide accurate speed ratios and position control, which is very important for precisely rotating and removing the product relative to the threaded core. At the same time, the gear transmission can easily achieve forward and reverse rotation, providing flexibility for the clamping jaws 57 to reset after the operation. In addition, the gear transmission can adopt a modular design, which is convenient for standardization and reduces the maintenance cost. Using gears as the driving member 55 and the driven members 56 for transmission in this embodiment of the rotating module does not mean that only gears can be used for transmission. Other transmissions such as gear racks can also be used. The specific selection can be determined by considering specific application requirements, such as load capacity, motion range, accuracy, maintenance requirements, and cost. The clamping jaw 57 includes a connecting portion 571, a clamping portion 572, and a limiting portion 573. The connecting portion 571 is connected to the transmission shaft 58. One end of the limiting portion 573 is connected to the connecting portion 571, and one end of the clamping portion 572 is connected to the limiting portion 573. Two bosses 574 are symmetrically provided at the end of the inner side of the limiting portion 573 away from the connecting portion 571, and a baffle is installed at the end of the limiting portion 573 away from the connecting portion 571. The area of the baffle is larger than the area of the end of the limiting portion 573 where the baffle is installed. In this embodiment, the clamping portion 572 is an L-shaped silicone gasket. One end of it is fixedly connected to the limiting portion 573, and the other end abuts against the boss 574. The end abutting against the boss 574 is used to clamp the product. The silicone gasket has good elasticity, can provide a stable clamping force, and at the same time reduce damage to the product. Furthermore, the silicone gasket has stable properties and can still maintain good performance after long-term use. Using an L-shaped silicone gasket for the clamping portion 572 in this embodiment does not mean that only silicone gaskets can be used. The specific selection can be determined by considering specific application requirements, such as clamping ability, shock resistance, maintenance requirements, and cost. The height of the boss 574 is lower than the height of the clamping end of the clamping portion 572. One end of it abuts against the clamping portion 572, and the other end abuts against the baffle. In this embodiment, the boss 574 is a nylon pad. When the clamping jaw 57 rotates with the product, the boss 574 contacts the product to prevent the product from being damaged during the core removal process. Nylon has the property of self-lubrication, can well reduce the friction between the clamping jaw 57 and the product, reduce the risk of scratches and wear, and at the same time the nylon material can reduce the noise generated by collisions. Using a nylon pad for the boss 574 in this embodiment does not mean that only nylon pads can be used. The specific selection can be determined by considering specific application requirements.The part of the jaw 57 of the rotation module in contact with the product is designed according to products of different model specifications. When the nominal diameter of the product is different, the size of the jaw 57 is also different. In this embodiment, the total space height inside the jaw 57 is 1 mm larger than the nominal diameter of the product. The specific selection can be determined by considering the specific requirements of the application. An inductive switch 59 is also installed on the rotation mechanism 5, and an inductor 575 is also installed on the jaw 57. The inductive switch 59 is communicatively connected to the inductor 575 and is used for the motor 54 to find the origin after rotation for the next operation.

[0040] The slide rail mechanism 2 of this embodiment includes a first slide rail mechanism 21 and a second slide rail mechanism 22. The fixing mechanism 4 is installed on the first slide rail mechanism 21, and the rotation mechanism 5 is installed on the second slide rail mechanism 22. The slide rail mechanism 2 includes a slide rail and a slider. The slider of the first slide rail mechanism 21 is fixedly connected to the fixing mechanism 4, and the slider of the second slide rail mechanism 22 is fixedly connected to the rotation mechanism 5, realizing the stable high-precision linear sliding of the fixing mechanism 4 and the rotation mechanism 5 along a predetermined line. The first slide rail mechanism 21 and the second slide rail mechanism 22 can be arranged in a cross shape as shown in Figure 1 the figure, or the first slide rail mechanism 21 and the second slide rail mechanism 22 are arranged on a straight line. The selection of the slide rail and slider in this embodiment does not mean that only the slide rail and slider can be used. It can also be selected according to factors such as different load capacities, precision requirements, installation environments, and operating speeds. For example, gear-rack transmission, belt transmission, etc. When selecting, it is necessary to comprehensively consider factors such as specific application requirements, cost budget, load requirements, speed requirements, and working environment.

[0041] The drive mechanism 6 of this embodiment includes a first drive mechanism 61 and a second drive mechanism 62. The first drive mechanism 61 is connected to the fixing mechanism 4, and the second drive mechanism 62 is connected to the rotation mechanism 5. The drive mechanism 6 of this embodiment uses a feeding cylinder, which can realize the reciprocating movement of the fixing mechanism 4 and the rotation mechanism 5 on the slide rail. First, the cylinder structure is simple, with high reliability and easy maintenance. Second, compared with electric or hydraulic systems, the pneumatic system has a lower cost. Moreover, the cylinder uses compressed air as the power source, eliminating the worry of oil leakage and being cleaner and more environmentally friendly. Further, the cylinder is easy to realize multi-station control: multiple cylinders can be controlled simultaneously through a distributor to achieve complex actions. Although the feeding cylinder has the above advantages, alternative solutions may need to be considered in some applications. Electric cylinders, hydraulic cylinders, gear racks and other mechanical transmission systems can also be used for replacement. When selecting, it is necessary to comprehensively consider factors such as specific application requirements, cost budget, control precision, load requirements, speed requirements, and working environment.

[0042] The clamping mechanism 3 of the present utility model includes a clamping member 31 and a moving member 32. The moving member 32 is fixedly connected to the frame 1 through a mounting plate 11, and the clamping member 31 is movably connected to the moving member 32. When performing the core removal operation, the two clamping members 31 of the clamping mechanism 3 move to directly above the fixing mechanism 4 to clamp and fix the sprue, preventing the sprue from rotating when the product rotates and causing the product and the sprue to be inseparable. After the core removal is completed, the product falls into the hopper frame 8, and the clamping member 31 resets, that is, the clamping member 31 moves away from the fixing mechanism 4, and the sprue falls into the hopper frame 8.

[0043] This embodiment can be used in cooperation with a manipulator. The manipulator removes the product to be core-removed from the injection molding machine and places the product to be core-removed on the fixing mechanism 4. There is a core fixing pin on the fixing mechanism 4, and this fixing pin is matched with the perforation on the core to be core-removed to achieve the positioning and fixing of the core. The first driving mechanism 61 transports the fixing mechanism 4 to the side of the first rotating mechanism 51. The clamping mechanism 3 clamps and fixes the sprue. The second driving mechanism 62 drives the rotating mechanism 5 to the demolding position. At this time, the motor 54 of the rotating mechanism 5 operates to achieve the simultaneous core removal of two products. After the core removal is completed, the product and the sprue fall into the hopper frame 8, and the core is taken away by the manipulator and placed into the injection molding machine. The motor 54 of the rotating mechanism 5 retrieves the origin through the communication connection between the induction switch 59 and the inductor 575, facilitating the next core removal operation.

[0044] Embodiment 2

[0045] As Figure 4The second embodiment of an automatic core-pulling device of the present utility model is shown. This embodiment is similar to Embodiment 1, except that there are at least two rotating mechanisms 5. Two rotating mechanisms 5 form a group and are symmetrically arranged on both sides of the fixing mechanism 4. Each group of rotating mechanisms 5 is arranged in parallel. In this embodiment, two rotating mechanisms 5 are selected. The rotating mechanism 5 includes a first rotating mechanism 51 and a second rotating mechanism 52. The slide rail mechanism 2 includes a first slide rail mechanism 21, a second slide rail mechanism 22, and a third slide rail mechanism 23. The slide rail mechanism 2 is arranged in a cross shape on the frame 1. The driving mechanism 6 includes a first driving mechanism 61, a second driving mechanism 62, and a third driving mechanism 63. The fixing mechanism 4 is installed on the first slide rail mechanism 21, the first rotating mechanism 51 is installed on the second slide rail mechanism 22, and the second rotating mechanism 52 is installed on the third slide rail mechanism 23. The first driving mechanism 61 is connected to the fixing mechanism 4, the second driving mechanism 62 is connected to the first rotating mechanism 51, and the third driving mechanism 63 is connected to the second rotating mechanism 52. The driving mechanism 6 is arranged in a cross shape on the frame 1. Injection molds generally adopt a multi-cavity structure. Each mold has 4 products that need to be separated from the sprue and the core. It can be used in cooperation with a manipulator. The manipulator removes the product to be core-pulled from the injection molding machine and places the product to be core-pulled on the fixing mechanism 4. There is a core fixing pin on the fixing mechanism 4, which is matched with the perforation on the core to be core-pulled to realize the positioning and fixing of the core. The first driving mechanism 61 transports the fixing mechanism 4 to the middle of the first rotating mechanism 51 and the second rotating mechanism 52. The clamping mechanism 3 clamps and fixes the sprue. The second driving mechanism 62 and the third driving mechanism 63 respectively drive the first rotating mechanism 51 and the second rotating mechanism 52 to the demolding position. At this time, the motors 54 of the two rotating mechanisms 5 move to realize the simultaneous core-pulling of the four products. After the core-pulling is completed, the clamping jaws 57 release the products, and the products fall into the hopper frame 8. Then the paging mechanism 10 blocks the hopper frame 8. The clamping mechanism 3 releases the sprue, and the sprue falls into the hopper frame 8. The core is taken away by the manipulator and put into the injection molding machine. The motors 54 of the two rotating mechanisms 5 find the origin through the communication connection between the induction switch 59 and the inductor 575, which is convenient for the next core-pulling operation. Multiple cores can be demolded in one operation, and at the same time, the separation of the product and the sprue is completed.

[0046] In this embodiment, two rotating mechanisms 5 are selected, that is, one group is selected. The rotating mechanism 5 can also be multiple. Each group of rotating mechanisms 5 is arranged in parallel, and the fixing mechanism 4 is installed in the middle of the two rotating mechanisms 5. If an odd number of rotating mechanisms 5 are selected, two form a group, each group is placed in parallel, and the remaining one rotating mechanism 5 can be arranged in parallel with any one rotating mechanism 5 in other groups. If multiple groups of rotating mechanisms 5 are selected, the number of fixing mechanisms 4 and driving mechanisms 6 should also correspond.

[0047] Embodiment 3

[0048] As Figure 5Shown below is the third embodiment of an automatic core removal device of the present utility model. This embodiment is similar to Embodiment 2, except that a safety light curtain 7, a hopper frame 8, a sprue frame 9, a paging mechanism 10, and a solenoid valve 12 are further installed on the frame 1 of this embodiment. The solenoid valve 12 installed on the frame is connected to the drive mechanism 6 and can connect or disconnect different air paths to control the driving direction of the drive mechanism 6, thereby achieving the control of the fixing mechanism 4 and the rotating mechanism 5. The safety light curtain 7 is installed on both sides of the first slide rail mechanism 21. As a safety control device, the safety light curtain 7 detects and controls the movement of people and objects through the physical barrier between the transmitter and the receiver. When a person or an object enters the detection area of the light curtain, the light is blocked, and the sensor can identify and send a signal to trigger corresponding safety measures to avoid accidents. The safety light curtain 7 is widely used in multiple fields such as industrial automation, traffic safety, and residents' lives. In industrial automation, the safety light curtain 7 can monitor personnel and objects on the production line with high precision to ensure safe production and reduce the possibility of operators being injured in the working environment. A universal caster 13 with a brake is also installed at the lower end of the frame of the present utility model, enabling the device to be easily moved or fixed, facilitating transfer or rearrangement between different locations.

[0049] A paging mechanism 10 is installed between the hopper frame 8 and the sprue frame 9. After the product core removal is completed, first, the paging mechanism 10 blocks the sprue frame 9, the gripper 57 releases the product, and the product falls into the hopper frame 8. Then, the paging mechanism 10 blocks the hopper frame 8, and the clamping mechanism 3 releases the sprue, and the sprue falls into the sprue frame 9. Multiple cores can be demolded in one operation, and at the same time, the automatic separation of the product and the sprue is completed.

[0050] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model and are not limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
