Description

Technical Field

[0001] This application relates to the field of mold processing technology, and in particular to a mold processing locking mechanism. Background Technology

[0002] Molds are tools used in manufacturing to mass-produce products of specific shapes. They can force raw materials such as metal and plastic to be shaped according to a design through a preset structure. They are characterized by customization, high repeatability, and the need for external force assistance. Common types include stamping dies and injection molds. They are key equipment for achieving standardized and high-precision mass production.

[0003] During mold processing, a locking mechanism is needed to limit and fix its position for subsequent stable processing. Chinese Patent No. CN217494023U discloses a mold processing locking mechanism, including a locking mechanism body. The locking mechanism body includes a fixed seat, and a displacement mechanism is installed on the side of the fixed seat. A movable column is installed on the displacement mechanism, and a movable plate is fixed to one end of the movable column. A slot is opened on the fixed seat, and a support component is installed inside the slot. First, the mold is placed on the limiting seat, and the support component is displaced and adjusted inside the slot to adjust the contact position with the mold, thereby changing the fixing point. After the adjustment is completed, the displacement mechanism is activated. The displacement mechanism pushes the movable plate to move through the movable column. The movable plate cooperates with the fixed plate to push the slider to move inside the slot. During the movement, one side of the slider contacts the inner wall of the slot for limiting and fixing, and one side of the support seat contacts the mold to complete the extrusion and fixing.

[0004] However, in the above-mentioned patent, when positioning and locking the mold, it is necessary to operate four displacement mechanisms separately so that one side of the support base can contact the mold for compression and fixation. When operating the displacement mechanisms, the movable column 18 also needs to push the movable plate 5 to move. Therefore, the process of fixing the four displacement mechanisms separately is cumbersome, which reduces the locking speed before mold processing and affects processing efficiency. Therefore, in order to solve the above problems, we provide a mold processing locking mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a mold processing locking mechanism to solve the problem mentioned in the background art that when positioning and locking a mold, it is necessary to operate four displacement mechanisms separately to make one side of the support base contact the mold for compression and fixation. When operating the displacement mechanisms, the movable column 18 also needs to push the movable plate 5 to move. Therefore, the process of fixing the four displacement mechanisms separately is cumbersome, which reduces the locking speed before mold processing and affects the processing efficiency.

[0006] The embodiments of this application adopt the following technical solutions: A mold processing locking mechanism includes a positioning and locking platform. Two sliding plates are positioned above the positioning and locking platform. Adjustable covers are fixedly mounted on the upper surfaces of both sliding plates. Positioning and locking blocks are slidably connected to the inner walls of both adjustable covers. Elastic positioning elements are provided on the upper surfaces of both adjustable covers. Connecting blocks are fixedly connected to the bottom surfaces of both sliding plates. Transmission plates are hinged to the bottom surfaces of both connecting blocks via pins. An electro-hydraulic actuator is fixedly mounted on the bottom surface of the positioning and locking platform. A lifting seat is fixedly mounted on the telescopic end of the electro-hydraulic actuator. A lifting plate is fixedly mounted on the bottom surface of the lifting seat. The ends of the two transmission plates that are close to each other are respectively hinged to the left and right ends of the lifting plate via pins. Buffer pads are fixedly connected to the sides of the two positioning and locking blocks that are close to each other.

[0007] Preferably, the elastic positioning component includes a support cover fixedly connected to the upper surface of the adjusting cover, a limiting slide plate slidably connected to the inner wall of the support cover, a positioning block fixedly connected to the bottom surface of the limiting slide plate, a set of positioning slots opened on the upper surface of the positioning locking block, one end of the positioning block extending into the interior of the positioning slot, and the outer surface of the positioning block in close contact with the inner wall of the positioning slot, a sliding pull plate fixedly connected to the upper surface of the limiting slide plate, a pull plate sliding hole opened on the upper surface of the support cover, the top end of the sliding pull plate penetrating through the pull plate sliding hole and extending above the pull plate sliding hole, a limiting pull handle fixedly connected to the top end of the sliding pull plate, and two springs fixedly connected to the upper surface of the limiting slide plate, the top ends of the two springs being fixedly connected to the inner top wall of the support cover.

[0008] Preferably, the bottom surface of the positioning and locking platform is fixedly connected to two support seats, each of the two support seats has a sliding groove on one side, and each of the two sliding grooves has a slider slidably connected to its inner wall. The sides of the two sliders that are close to each other are fixedly connected to the outer surface of the lifting seat.

[0009] Preferably, the upper surface of the positioning and locking platform has two transmission sliding holes, and the outer surfaces of the two connecting blocks are slidably connected to the inner walls of the two transmission sliding holes respectively.

[0010] Preferably, the upper surface of the positioning and locking platform is provided with two sets of L-shaped grooves, and the inner walls of the two sets of L-shaped grooves are slidably connected with limit blocks. The upper surfaces of the two sets of limit blocks are respectively fixedly connected to the bottom surfaces of the two sliding plates.

[0011] Preferably, the bottom surface of the positioning and locking platform is fixedly connected to two sets of mounting supports, and the two sets of mounting supports are fixedly connected to a support base on their adjacent sides, and the bottom surfaces of the two supports are fixedly connected to the upper surface of the support base.

[0012] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: This mold processing locking mechanism, through the cooperation of an elastic positioning component and a positioning locking block, enables convenient fine-tuning of the locking distance. Pulling the limit handle causes the positioning block to disengage from the positioning slot, and pushing the positioning locking block to slide along the adjustment cover allows for quick adjustment of the extension length. Releasing the limit handle causes the spring to return and lock the position. This adjustment method does not require disassembly or replacement of parts, can quickly adapt to molds of different widths and sizes, reduces the difficulty of adjustment during mold changes, reduces locking time caused by changes in mold specifications, and solves the problem of poor adaptability of traditional mechanisms.

[0013] This mold processing locking mechanism, through the setting of electro-hydraulic push rod and transmission structure, only requires the operation of one electro-hydraulic push rod to drive the lifting plate to rotate the transmission plate, and then pulls the two sliding plates to move synchronously in opposite directions through the connecting block. This facilitates the two positioning locking blocks to drive the two buffer fixing pads, thereby achieving rapid locking of the mold, improving the locking speed and ensuring the locking stability, and solving the problems of low efficiency and cumbersome operation of traditional mechanisms.

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Example 1 As attached Figures 1-5 The mold processing locking mechanism shown includes a positioning locking platform 1. Two sliding plates 2 are arranged above the positioning locking platform 1. Adjustable covers 8 are fixedly installed on the upper surfaces of both sliding plates 2. Positioning locking blocks 10 are slidably connected to the inner walls of both adjustable covers 8. Elastic positioning elements 9 are provided on the upper surfaces of both adjustable covers 8. Connecting blocks 7 are fixedly connected to the bottom surfaces of both sliding plates 2. Transmission plates 6 are hinged to the bottom surfaces of both connecting blocks 7 via pins. An electro-hydraulic push rod 3 is fixedly installed on the bottom surface of the positioning locking platform 1. The hydraulic actuator 3 is a drive device that integrates a motor, hydraulic pump, hydraulic cylinder, etc. It can convert electrical energy into mechanical energy to achieve linear reciprocating motion. The speed can be adjusted and the start and stop can be smoothly controlled by the motor. It is widely used in the field of mechanical automation. The telescopic end of the electro-hydraulic actuator 3 is fixedly installed with a lifting seat 4. The bottom surface of the lifting seat 4 is fixedly installed with a lifting plate 5. The two transmission plates 6 are respectively hinged to the left and right ends of the lifting plate 5 by pins. The two positioning locking blocks 10 are fixedly connected to the side of their respective adjacent sides with buffer fixing pads 12.

[0018] As can be seen from the above description, this utility model has the following beneficial effects: by setting up the electro-hydraulic push rod 3 and the transmission structure, only one electro-hydraulic push rod 3 needs to be operated to drive the lifting plate 5 to drive the transmission plate 6 to rotate, and then the connecting block 7 pulls the two sliding plates 2 to move synchronously in opposite directions, so that the two positioning locking blocks 10 can drive the two buffer fixing pads 12 to achieve rapid locking of the mold, improve the locking speed, and ensure the locking stability, thus solving the problems of low efficiency and cumbersome operation of traditional mechanisms.

[0019] Example 2 Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: In this embodiment, the elastic positioning member 9 includes a support cover 91 fixedly connected to the upper surface of the adjusting cover 8. A limiting slide plate 92 is slidably connected to the inner wall of the support cover 91. A positioning block 95 is fixedly connected to the bottom surface of the limiting slide plate 92. A set of positioning slots 11 are opened on the upper surface of the positioning locking block 10. One end of the positioning block 95 extends into the interior of the positioning slot 11, and the outer surface of the positioning block 95 is in close contact with the inner wall of the positioning slot 11. A sliding pull plate 93 is fixedly connected to the upper surface of the limiting slide plate 92. A pull plate sliding hole 97 is opened on the upper surface of the support cover 91. The top end of the sliding pull plate 93 passes through the pull plate sliding hole 97 and extends above the pull plate sliding hole 97. A limiting handle 94 is fixedly connected to the top end of the sliding pull plate 93. Two springs 96 are fixedly connected to the upper surface of the limiting slide plate 92. The top of each of the 96 is fixedly connected to the inner top wall of the support cover 91. Furthermore, by sliding the limiting slide plate 92 on the inner wall of the support cover 91, the positioning block 95 on the bottom surface can be moved synchronously. When the positioning block 95 is engaged in the positioning slot 11 of the positioning locking block 10, the position of the positioning locking block 10 can be quickly locked, preventing the positioning locking block 10 from shifting when the mold is locked. The limiting handle 94 at the top of the sliding pull plate 93 is convenient for the operator to pull, thereby driving the limiting slide plate 92 to compress the spring 96, causing the positioning block 95 to disengage from the positioning slot 11, realizing the position adjustment of the positioning locking block 10. By utilizing the rebound effect of the spring 96, the limiting slide plate 92 can be pushed back to its original position after the limiting handle 94 is released, ensuring that the positioning block 95 is stably engaged in the positioning slot 11, and ensuring that the position of the positioning locking block 10 is fixed after adjustment.

[0020] In this embodiment, the bottom surface of the positioning and locking platform 1 is fixedly connected to two support seats 13. Each support seat 13 has a sliding groove 14 on one side. The inner walls of each sliding groove 14 are slidably connected to sliders 15. The sides of the two sliders 15 that are close to each other are fixedly connected to the outer surface of the lifting seat 4. The upper surface of the positioning and locking platform 1 has two transmission sliding holes 20. The outer surfaces of the two connecting blocks 7 are slidably connected to the inner walls of the two transmission sliding holes 20. The upper surface of the positioning and locking platform 1 has two sets of L-shaped grooves 16. The inner walls of the two sets of L-shaped grooves 16 are slidably connected to limit blocks 17. The upper surfaces of the two sets of limit blocks 17 are fixedly connected to the bottom surfaces of the two sliding plates 2. The bottom surface of the positioning and locking platform 1 is fixedly connected to two sets of... The mounting supports 19 are connected to the support base 18 on their adjacent sides. The bottom surfaces of the two support seats 13 are fixedly connected to the upper surface of the support base 18. Furthermore, the support seats 13 cooperate with the slider 15 and the slide groove 14 to provide stable guidance for the movement of the lifting seat 4, ensuring the stability of the transmission of the lifting plate 5 to the transmission plate 6. The transmission slide hole 20 ensures that the connecting block 7 moves the sliding plate 2 without jamming. The L-shaped groove 16 and the limit block 17 slide together to ensure that the two sliding plates 2 move smoothly towards the mold. The mounting supports 19 cooperate with the support base 18 to increase the contact area between the mechanism and the ground, lower the center of gravity of the mechanism, and prevent the whole mechanism from shaking or tipping when the mold is locked.

[0021] The working process of this utility model is as follows: When the mold processing locking mechanism is adapted to molds of different sizes, pulling the limiting handle 94 of the elastic positioning component 9 can drive the sliding plate 93 to move upward along the sliding hole 97 of the support cover 91, thereby pulling the limiting slide plate 92 to compress the spring 96, which can make the positioning block 95 disengage from the positioning slot 11 of the positioning locking block 10. At this time, the positioning locking block 10 can be pushed to slide along the inner wall of the adjusting outer cover 8 to adjust the extension length of the positioning locking block 10. Then, the limiting handle 94 is released, the spring 96 rebounds and pushes the limiting slide plate 92 downward, so that the positioning block 95 is re-engaged into the corresponding positioning slot 11, locking the position of the positioning locking block 10. Next, the mold is placed above the positioning and locking platform 1, and the electro-hydraulic actuator 3 is activated to extend, which drives the lifting plate 5 to descend synchronously. The two ends of the lifting plate 5 are hinged to the transmission plate 6 through pins. When the lifting plate 5 moves, it pulls the transmission plate 6, causing the transmission plate 6 to rotate around the hinge point. The other end of the transmission plate 6 is hinged to the connecting block 7, which in turn drives the connecting block 7 to slide along the transmission sliding hole 20 of the positioning and locking platform 1. Since the top of the connecting block 7 is fixed to the sliding plate 2, the two sliding plates 2 are finally driven to move towards each other along the positioning and locking platform 1. This process only requires operating one electro-hydraulic actuator 3 to realize that the two sliding plates 2 can move towards the mold synchronously, thereby increasing the mold locking speed. This is the working process and working principle of the device.
