Description

Technical Field

[0001] This utility model relates to the technical field of calibration devices for mold production, and in particular to a calibration device for mold production. Background Technology

[0002] With the continuous development of society and the continuous progress of science and technology, the technology related to calibration devices for mold production is also constantly improving. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products. Injection molds are required in injection molding. During production, injection molds need to be calibrated and positioned to prevent misalignment of parts.

[0003] The patent document with publication number "CN218196677U" discloses a calibration device for mold production, including a base, a calibration groove on the top of the base, and a set of T-shaped calibration fixing plates arranged in the calibration groove along the width direction.

[0004] Although the aforementioned patent documents have solved the problems of calibration plate shaking during calibration, leading to calibration errors, and difficulty in handling the mold after calibration, the following drawbacks still exist: after the mold is lifted and removed using a suction cup, the suction connection between the suction cup and the mold is relatively tight, making it difficult to quickly separate the suction cup and the mold. This makes it difficult for staff to quickly handle and transfer the mold, which is not conducive to the use of the calibration device. Utility Model Content

[0005] The purpose of this invention is to address the following shortcomings in the prior art: after the mold is lifted and removed using a suction cup, the adsorption connection between the suction cup and the mold is relatively tight, making it difficult to quickly separate the suction cup and the mold. This makes it inconvenient for workers to quickly handle and transfer the mold, which is not conducive to the use of calibration devices. Therefore, this invention proposes a calibration device for mold production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A calibration device for mold production includes a base, on which two rotating shafts are rotatably connected. A transmission wheel is fixedly connected to each of the two rotating shafts. The two transmission wheels are connected by a transmission belt. A cam and a disc are fixedly connected to one of the rotating shafts. The base has an installation cavity, in which an airbag and a hollow fixing tube are fixedly connected. The airbag is connected to the hollow fixing tube via a hose. A compression assembly is provided in the installation cavity. The hollow fixing tube is rotatably connected to the disc. An annular cavity communicating with the hollow fixing tube is provided in the disc. A fixing frame is fixedly connected to the disc. A cylinder is fixedly installed in the fixing frame. An electric telescopic rod is fixedly connected to the drive end of the cylinder. A suction cup is connected to the electric telescopic rod via a fixing block. A hollow shell is fixedly connected to the electric telescopic rod. A sliding assembly is provided on the hollow shell.

[0007] Preferably, the sliding assembly includes a sealing plate slidably mounted on the hollow housing, a telescopic strip is fixedly connected to one side of the sealing plate, a cover plate is fixedly connected to the telescopic end of the telescopic strip, a through hole communicating with the suction cup is opened on the fixing block, and the surface of the cover plate is in contact with the surface of the fixing block.

[0008] Preferably, a first spring is fixedly connected to one side of the sealing plate, and the first spring is fixedly connected to the inner wall of the hollow shell.

[0009] Preferably, a telescopic tube is fixedly connected to the disc, and the telescopic end of the telescopic tube is fixedly connected to the hollow shell.

[0010] Preferably, the extrusion assembly includes a sliding plate, and the inner walls on both sides of the mounting cavity are provided with grooves for the sliding plate to slide back and forth.

[0011] Preferably, a second spring is fixedly connected to one inner wall of each of the slides, and the second spring is fixedly connected to the slide plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When it is necessary to separate the suction cup from the mold, the servo motor drives the rotating shaft to rotate. The cam squeezes the sliding plate, and the sliding plate squeezes the airbag during its movement. This causes the gas in the airbag to enter the hollow fixed tube through the hose, and then enter the annular cavity of the disc. The gas then enters the telescopic tube through the annular cavity and is finally delivered to the hollow shell. This causes the sealing plate to slide inside the hollow shell. In the initial state, the cover plate is attached to the through hole of the fixed block, sealing the through hole. When the sealing plate slides, one end of the telescopic strip is fixedly connected to the sealing plate. The telescopic strip can drive the cover plate to move, separating the cover plate from the through hole of the fixed block. This breaks the adsorption air pressure environment between the suction cup and the mold, making it easier to quickly separate the suction cup from the mold. This makes it easier for the staff to pick up and transfer the mold, which is beneficial for the use of the calibration device. Attached Figure Description

One of the rotating shafts 12 is fixedly connected to the drive end of the servo motor. A transmission wheel is fixedly connected to each of the two rotating shafts 12, and the two transmission wheels are connected by a transmission belt. A cam 16 and a disc 2 are fixedly connected to one of the rotating shafts 12. An installation cavity is provided inside the base 1. An airbag 13 and a hollow fixing tube 11 are fixedly connected inside the installation cavity. The airbag 13 is connected to the hollow fixing tube 11 through a hose 15. An extrusion assembly is provided inside the installation cavity. The hollow fixing tube 11 and the disc 2 are rotatably connected and the connection is well sealed. An annular cavity communicating with the hollow fixing tube 11 is provided inside the disc 2. A fixing frame 3 is fixedly connected to the disc 2. A cylinder 4 is fixedly installed inside the fixing frame 3. An electric telescopic rod 8 is fixedly connected to the drive end of the cylinder 4.

A cover plate 10 is fixedly connected to the telescopic end of the telescopic strip 9. A through hole communicating with the suction cup 5 is opened on the fixing block 6. The surface of the cover plate 10 is in contact with the surface of the fixing block 6. A first spring 18 is fixedly connected to one side of the sealing plate 17. The first spring 18 is fixedly connected to the inner wall of the hollow housing 7. In the initial state, the first spring 18 maintains the position of the sealing plate 17, and the cover plate 10 is in contact with the through hole of the fixing block 6 to seal and block the through hole.

[0019] refer to Figure 2 and Figure 3 A telescopic tube 19 is fixedly connected to the disc 2. The telescopic tube 19 has good airtightness. The telescopic end of the telescopic tube 19 is fixedly connected to the hollow shell 7. The extrusion assembly includes a sliding plate 14. The inner walls on both sides of the mounting cavity are provided with grooves for the sliding plate 14 to slide back and forth. A second spring is fixedly connected to one side of the inner wall of each groove. The second spring and the sliding plate 14 are fixedly connected. When it is necessary to separate the suction cup 5 from the mold, the servo motor drives the rotating shaft 12 to rotate. When the cam 16 rotates with the rotating shaft 12, it will squeeze the sliding plate 14. The sliding plate 14 slides along the groove and compresses the second spring. During the movement of the sliding plate 14, it will squeeze the airbag 13, so that the gas in the airbag 13 enters the hollow fixed tube 11 through the hose 15, and then the gas enters the disc 2. The material enters the annular cavity and then the telescopic tube 19, eventually being transported into the hollow shell 7. Due to the good sealing performance between the sealing plate 17 and the inner wall of the hollow shell 7, the sealing plate 17 slides within the hollow shell 7. In the initial state, the first spring 18 maintains the position of the sealing plate 17, and the cover plate 10 adheres to the through hole of the fixing block 6, sealing and blocking the through hole. When the sealing plate 17 slides, the first spring 18 deforms, and one end of the telescopic strip 9 is fixedly connected to the sealing plate 17. The telescopic strip 9 can drive the cover plate 10 to move, causing the cover plate 10 to separate from the through hole of the fixing block 6, thus disrupting the adsorption air pressure environment between the suction cup 5 and the mold. This facilitates the rapid separation of the suction cup 5 and the mold, making it convenient for staff to pick up and transfer the mold.

[0020] In this invention, when it is necessary to separate the suction cup 5 from the mold, the servo motor drives the rotating shaft 12 to rotate. When the cam 16 rotates with the rotating shaft 12, it will squeeze the sliding plate 14. The sliding plate 14 slides along the slide groove and compresses the second spring. During the movement of the sliding plate 14, it will squeeze the airbag 13, causing the gas in the airbag 13 to enter the hollow fixed tube 11 through the hose 15, and then enter the annular cavity of the disc 2, and then enter the telescopic tube 19 through the annular cavity. Finally, the gas is delivered to the hollow shell 7. Due to the good sealing performance when the sealing plate 17 is connected to the inner wall of the hollow shell 7, ... The sealing plate 17 slides within the hollow housing 7. In the initial state, the first spring 18 maintains the position of the sealing plate 17, and the cover plate 10 adheres to the through hole of the fixing block 6 to seal and block the through hole. When the sealing plate 17 slides, the first spring 18 deforms, and one end of the telescopic strip 9 is fixedly connected to the sealing plate 17. The telescopic strip 9 can drive the cover plate 10 to move, causing the cover plate 10 to separate from the through hole of the fixing block 6, thereby disrupting the adsorption air pressure environment between the suction cup 5 and the mold. This facilitates the quick separation of the suction cup 5 and the mold, making it easier for staff to pick up and transfer the mold, which is beneficial for the use of the calibration device.
