Description

Technical Field

[0001] This utility model belongs to the field of mold opening and forming technology, and in particular relates to an infrared magnetic induction mold opening device. Background Technology

[0002] Mold manufacturing is an indispensable part of modern industrial production, widely used in many fields such as automobiles, electronics, home appliances, and aerospace. With the continuous advancement of industrial technology, higher requirements are placed on the precision, production efficiency, and automation level of molds. The infrared magnetic induction mold opening device is a device that combines infrared detection technology and magnetic induction technology to automatically control the mold opening and closing process. It is mainly used in mold manufacturing fields such as injection molding, die casting, and rubber molding.

[0003] During the use of existing equipment, the cylinder, as the actuator of the mold opening device, may experience problems such as seal wear, piston rod jamming, and internal air leakage due to long-term high-frequency operation. If quick disassembly is not performed, the replacement of the cylinder may take a lot of time, which may affect the work efficiency of the staff. Utility Model Content

[0004] The purpose of this invention is to provide an infrared magnetic induction mold opening device to solve the problem in the above-mentioned mold opening technology where the actuator is damaged and replacement requires a lot of time, thus affecting work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an infrared magnetic induction mold opening device, comprising a base plate, on the upper surface of which a guide seat is fixedly mounted. Two molds capable of moving towards each other are slidably connected to the guide seat. Two parallel connecting brackets are mounted on the lower sides of the two molds. The connecting brackets have strip-shaped holes with their length direction along the vertical direction. A drive cylinder is detachably connected to the upper part of the base plate. Support frames are mounted on both sides of the outer diameter of the telescopic rod of the drive cylinder. A telescopic shaft capable of axial movement is connected to the inner side of the two support frames. The telescopic shaft can be inserted into the strip-shaped holes of the connecting brackets. During operation, the drive cylinder can drive the two molds to move towards each other. When changing molds, the telescopic shaft can be disengaged from the strip-shaped holes for quick mold replacement.

[0007] By adopting the above technical solution, the two molds are closed and opened using the drive cylinders at both ends, replacing the manual operation method. This has the advantages of saving manpower and increasing work efficiency. In addition, the telescopic shaft at the front end of the drive cylinder can be inserted into the slot of the connecting bracket and can quickly disengage from the slot, which can significantly improve the efficiency of mold changing and reduce the dependence on manual operation during mold changing, thus solving the problem of cumbersome mold changing in the mold opening process.

[0008] Optionally, cylinder seats are fixedly installed on both sides of the upper part of the base plate. A rotatable shaft is installed on the surface of the cylinder seat, and a pressure plate is fixedly installed on the shaft. The pressure plate has an arc-shaped structure in the middle, and a locking bolt is provided at the end of the pressure plate away from the shaft. The drive cylinder can be placed in the middle of the pressure plate, and the drive cylinder is fixed to the cylinder seat by the pressure plate.

[0009] By adopting the above technical solution and setting up a cylinder seat, rotating shaft and clamping plate structure, the drive cylinder can be quickly installed and securely locked, avoiding displacement or loosening of the drive components during operation, thereby ensuring the stability and repeatability of the mold opening and closing motion; at the same time, this structure makes cylinder installation and disassembly more convenient, and can also be disassembled to assist in mold replacement when it is inconvenient to replace the mold.

[0010] Optionally, the support frame has an L-shaped structure, a guide sleeve is installed on the support frame, the telescopic shaft is slidably connected inside the guide sleeve, and a limiting plate is provided on the outer wall of the telescopic shaft. A spring is sleeved on the telescopic shaft between the limiting plate and the support frame.

[0011] By adopting the above technical solution, by setting a guide sleeve on the L-shaped support frame and cooperating with the limiting plate and spring, the telescopic shaft has good guiding and return capabilities during insertion and disengagement from the strip hole, effectively improving the stability and safety of the device during operation, preventing the telescopic shaft from deviating or jamming, and enhancing the positioning stability of the mold during operation.

[0012] Optionally, blind holes are provided on both sides of the outer wall of the telescopic rod of the drive cylinder. Under the elastic force of the spring, the end of the telescopic shaft can move towards the telescopic rod of the drive cylinder and be inserted into the blind hole.

[0013] By adopting the above technical solution, the automatic locking function can be realized without manual intervention, which not only improves the positioning accuracy of the mold, but also simplifies the operation process.

[0014] Optionally, a damping plate is installed on the middle surface of the guide seat, and the lower surface of the mold can fit in contact with the damping plate.

[0015] The above technical solution is adopted because a sealing mold is provided above the workpiece during the hydroforming process. When working, the sealing mold forms a covering and pressing structure on the two molds. On the one hand, it prevents the mold from opening under the force of high-pressure liquid, and on the other hand, it can effectively limit the product in the vertical direction to ensure molding accuracy. Therefore, in order to avoid the sealing mold directly acting on the mold surface during the pressing process and causing damage to the mold or workpiece, a damping plate is specially set in the middle of the guide seat. This structure can play a buffering and shock absorption role, effectively extending the mold life.

[0016] Optionally, a gap is formed between the two connecting brackets on the lower side of the mold, and the telescopic rod of the drive cylinder can extend into this gap.

[0017] By adopting the above technical solution, after the telescopic rod of the drive cylinder extends into the gap, the telescopic shafts on both sides can pass through the strip hole and connect with the blind hole of the telescopic rod, thereby achieving the connection effect between the drive cylinder and the mold.

[0018] Optionally, an upright plate is fixed to one side of the base plate, and an infrared sensor is installed on the upright plate.

[0019] By adopting the above technical solution, the position status of the mold can be monitored in real time, and high-precision position feedback control can be achieved in conjunction with the magnetic induction system of the drive cylinder, which improves the accuracy of the mold opening and closing action, significantly reduces the error of human judgment, and enables the mold to have a precise positioning effect.

[0020] Optionally, an air pump may also be included, which is connected to the drive cylinder via an air pipe.

[0021] By adopting the above technical solution, the drive cylinder can be connected to an external air source to meet the needs of operation.

[0022] Optionally, a mold core may be detachably installed at the middle position of the guide seat.

[0023] By adopting the above technical solution and using a detachable mold core structure, it is beneficial to make the mold core replaceable when processing different products.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] The cylinder of this utility model adopts an assembly structure with a pressing plate, which can realize quick replacement when the cylinder is damaged. It has the advantage of quick disassembly of the actuator, thus avoiding the problem of time-consuming cylinder replacement and improving work efficiency.

[0026] This utility model introduces a positioning method that combines infrared sensing with the magnetic induction of the drive cylinder itself. Combined with the drive cylinder and quick insertion and removal structure, it realizes automatic opening and closing and high-precision positioning of the mold, effectively replacing the manual operation method in the traditional water expansion mold opening process, reducing labor intensity, and improving operational stability and production efficiency.

[0027] The mold of this invention can be quickly changed, accurately positioned, and has good automatic reset and limit functions. It can significantly reduce mold change time, reduce reliance on manual experience, improve production flexibility and equipment utilization, and adapt to the manufacturing needs of multi-specification products.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-4As shown, an infrared magnetic induction mold opening device includes a base plate 1. A guide seat 3 is fixedly installed on the upper surface of the base plate 1. Two molds 4 that can move towards each other are slidably connected to the guide seat 3. In this example, the two molds 4 have a semi-circular structure and can be used to wrap the workpiece. In order to facilitate the two molds 4 to always move back and forth along the length direction of the guide sleeve 10 during operation, the center of the guide seat 3 is designed to be concave, and horizontal grooves are opened on the inner walls of both sides of the guide seat 3. The two sides of the molds 4 can be placed in the grooves to prevent the molds 4 from moving upwards of the guide seat 3 and causing detachment. It can be understood that the sliding motion relationship between the guide seat 3 and the molds 4 can also be designed as a dovetail groove structure. More specifically, in order to facilitate the replacement of the molds 4, the grooves or dovetail grooves can be designed to pass through both ends of the guide seat 3, so that when the molds 4 are replaced, they can be detached from the guide seat 3 after moving to the end of the guide seat 3.

[0035] Two parallel connecting brackets 17 are installed on the lower side of the two molds 4, forming a gap between them. The telescopic rod 13 of the drive cylinder 12 can extend into this gap. The connecting brackets 17 have a strip-shaped hole 18 on their upper surface, with the length of the strip-shaped hole 18 arranged vertically. The drive cylinder 12 is detachably connected to the upper part of the base plate 1. Support frames 9 are installed on both sides of the outer diameter of the telescopic rod 13 of the drive cylinder 12. The inner sides of the two support frames 9 are connected to a telescopic shaft 14 that can move axially. The telescopic shaft 14 can be inserted into the strip-shaped hole 18 of the connecting bracket 17. During operation, the drive cylinder 12 can drive the two molds 4 to move towards each other. When changing the molds 4, the telescopic shaft 14 can be disengaged from the strip-shaped hole 18, allowing for quick replacement of the molds 4.

[0036] Specifically, the telescopic shaft 14 and the telescopic rod 13 of the drive cylinder 12 are arranged perpendicularly to each other. The telescopic shaft 14 can be placed in the slotted hole 18. On the one hand, it can drive the mold 4 to move when the drive cylinder 12 moves. On the other hand, since there is a lifting and lowering sealing mold above the mold 4 during the water expansion process, the mold 4 and the product will move downward when the sealing mold is pressed down. The drive cylinder 12 is always in a fixed state. Therefore, the design of the slotted hole 18 can avoid the problem of excessive local stress on the telescopic rod 13 of the drive cylinder 12, play a certain role in giving way, and avoid damage to the drive cylinder 12.

[0037] Specifically, cylinder seats 2 are fixedly installed on both sides of the upper part of the base plate 1. A rotatable shaft 20 is installed on the surface of the cylinder seat 2. The shaft 20 is mounted on the cylinder seat 2 via bearings. A pressure plate 21 is fixedly installed on the shaft 20. The pressure plate 21 has an arc-shaped structure in the middle. A locking bolt 22 is provided at the end of the pressure plate 21 away from the shaft 20. The drive cylinder 12 can be placed in the middle of the pressure plate 21 and fixed to the cylinder seat 2 by the pressure plate 21. This arrangement is for the purpose of facilitating the quick replacement of the drive cylinder 12. On the other hand, when changing different molds 4, due to the inconsistency in the size of the molds 4, the fixed position of the drive cylinder 12 can be changed according to different molds 4, thereby expanding the applicability of the drive cylinder 12. Furthermore, during the mold 4 replacement stage, some larger molds 4 may also have the problem of not being able to be disassembled due to the presence of the end drive cylinder 12. Therefore, this design can quickly disassemble the drive cylinder 12 to meet the needs of quick mold 4 replacement.

[0038] Specifically, the support frame 9 has an L-shaped structure, and a guide sleeve 10 is installed on the support frame 9. The telescopic shaft 14 is slidably connected inside the guide sleeve 10, and a limiting plate 11 is provided on the outer wall of the telescopic shaft 14. A spring 15 is sleeved on the telescopic shaft 14 between the limiting plate 11 and the support frame 9. By utilizing the elastic force of the spring 15, the two telescopic shafts 14 can always have a tendency to move in opposite directions, thereby ensuring that the telescopic shaft 14 is in the slot 18 and achieving the docking effect with the mold 4. When the mold 4 is replaced, by pressing the limiting plate 11, the two telescopic shafts 14 can move in opposite directions, which can quickly disengage from the slot 18 and achieve the effect of quick disassembly of the mold 4.

[0039] Specifically, blind holes 16 are provided on both sides of the outer wall of the telescopic rod 13 of the drive cylinder 12. Under the elastic force of the spring 15, the end of the telescopic shaft 14 can move towards the telescopic rod 13 of the drive cylinder 12 and be inserted into the blind hole 16. This arrangement allows the telescopic shaft 14 to automatically insert into the blind hole 16 of the telescopic rod 13 under the elastic force of the spring 15, forming a stable connection structure during the movement of the drive mold 4. This improves the structural stability and transmission reliability of the mold 4 during the drive process and avoids the problem of bending or deformation caused by uneven force on both ends of the telescopic shaft 14.

[0040] Specifically, a damping plate 19 is installed on the middle surface of the guide seat 3, and the lower surface of the mold 4 can fit in contact with the damping plate 19. The damping plate 19 can be made of rubber. When the sealing mold moves down, the mold 4 can move down a certain size to avoid the sealing mold and the mold 4 making hard contact and causing damage to the parts.

[0041] Specifically, a vertical plate 6 is fixed to one side of the base plate 1, and an infrared sensor 7 is installed on the vertical plate 6. The infrared sensor 7 is directed toward the closed area of ​​the mold 4 and is used to detect the opening and closing state of the mold 4 in real time. In addition, since the drive cylinder 12 has a magnetic induction design in the conventional design, the combination of the two can further improve the positioning accuracy of the mold 4 and improve the response speed.

[0042] In this example, an air pump 8 is also included, which is connected to the drive cylinder 12 via an air pipe.

[0043] In this example, a mold core 5 is detachably installed at the middle position of the guide seat 3. The mold core 5 can be installed on the guide seat 3 by means of threaded connection. The mold core 5 is used to fit the workpiece (in this example, the workpiece is a stainless steel cup blank, which is a sleeve structure) onto the mold core 5. The inner cavity of the mold core 5 is hollow and connected to a high-pressure water source. After the sealing film is pressed down, water can enter the interior of the workpiece, thereby causing the workpiece to expand and form.

[0044] In addition, the mold opening device can be installed on the production line in the workshop. Automated robots are set up in the workshop. The robot's mechanical arm can clamp the workpiece transferred from the previous process and put the workpiece on the mold core 5. After the water expansion is completed, the robot takes the workpiece off the mold core 5 and places it in a designated position (such as a conveyor belt) for the next process. It is mainly used to connect automated production lines, reduce manpower and production costs, and this production method can also ensure the consistency and stability of product quality.

[0045] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
