Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a precision mold component assembly device. Background Technology

[0002] Molds are core tools in industrial production used to shape objects. They achieve precise processing by changing the physical state of materials and are often referred to as the "mother of industry." A mold is a precision tool composed of multiple parts that uses external force to shape raw materials (such as metals, plastics, and rubber) into parts of specific shapes and sizes. Its applications encompass processes such as blanking, forging, injection molding, and die casting, and it is widely used in the automotive, electronics, medical, and home appliance industries.

[0003] In the assembly of precision mold components, parts with complex shapes and uneven surfaces are often encountered. Traditional clamping mechanisms typically employ a fixed pressure application method, such as using bolt and nut structures or hydraulically or pneumatically driven plates to directly clamp the components. The drawback of this fixed method is that it's difficult to guarantee the uniformity of pressure application. When dealing with complex-shaped parts with uneven surfaces, it's challenging to apply pressure evenly across the entire contact surface. This results in significant pressure differences between different parts of the component during assembly. Excessive localized pressure can easily cause component deformation, affecting assembly accuracy, and in severe cases, even leading to component damage, increasing production and maintenance costs.

[0004] To address these issues, we provide a precision mold component assembly device. Utility Model Content

[0005] The purpose of this invention is to provide a precision mold component assembly device. By combining quick-release components and elastic support components, it solves the problem that the pressure uniformity of existing assembly devices is difficult to guarantee, which affects assembly accuracy and may even lead to component damage in severe cases.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a precision mold component assembly device, comprising a frame. A clamping assembly is fixedly connected to the bottom of the frame's inner cavity, and an elastic support assembly is fixedly connected to the top of the frame's inner cavity. A quick-release assembly is fixedly connected to the top of the elastic support assembly. The elastic support assembly includes a pressure plate, a connecting column is fixedly connected to the top of the pressure plate, a mounting plate is sleeved on the top of the connecting column, a movable rod is fixedly connected to the top of the mounting plate, a guide tube is sleeved on the surface of the movable rod, and a spring is fixedly connected to the top of the movable rod. The top of the mounting plate is movable with the connecting column via the quick-release assembly. The quick-release assembly includes a rotating shaft fixedly connected to the top of the mounting plate via a bearing. A drive disc is fixedly connected to the surface of the rotating shaft. A pin is inserted through the top of the drive disc. A spring is sleeved on the surface of the pin. A pull ring is fixedly connected to the top of the spring. The bottom of the pin extends into the inner cavity of the mounting plate. A pin is inserted through the inner cavity of the connecting post. A positioning plate is slidably connected to the surface of the pin. The bottom of the positioning plate is fixedly connected to the top of the mounting plate. A spring is sleeved on the surface of the pin. The other end of the pin contacts the surface of the drive disc.

[0008] The present invention is further configured such that the frame includes a base, and hydraulic telescopic rods are fixedly connected to the four corners of the top of the base. A top plate is fixedly connected to the top of the hydraulic telescopic rods. The top of the guide tube is fixedly connected to the bottom of the top plate. An installation groove is provided on the top of the base, and movable grooves are provided on both sides of the installation groove. Limiting grooves are provided at both the front and rear ends of the movable grooves. The base is used to place the parts of the precision mold. The hydraulic telescopic rods are used as the downward pressing force to press and assemble the parts. The movable grooves provide the movement space for the lead screw. The limiting grooves and limiting blocks cooperate to limit the clamping plate and prevent it from rotating with the lead screw.

[0009] The present invention is further configured such that the clamping assembly includes a dual-output shaft motor fixedly connected to the inner cavity of the mounting groove. Both ends of the dual-output shaft motor are fixedly connected to lead screws, and the other end of the lead screws is threadedly connected to a threaded block. A clamping plate is fixedly connected to the top of the threaded block, and limit blocks are fixedly connected to the front and rear ends of the bottom of the clamping plate. The limit blocks are slidably connected to the inner cavity of the limit groove. The dual-output shaft motor can drive the two lead screws to rotate synchronously at the same time, ensuring the consistency of power. The clamping plate can clamp and fix the mold parts, which facilitates the installation of other parts.

[0010] The present invention is further configured such that the inner cavity of the threaded block is provided with a threaded hole for use with the lead screw, the threads on the surfaces of the left and right lead screws are designed in opposite directions, a rangefinder is fixedly connected to one side of each of the two clamping plates, and a rubber pad is fixedly connected to one side of each of the two clamping plates. The threaded hole and the lead screw can drive the threaded block to move, which in turn can drive the clamping plates to move. The reverse thread design on the surfaces of the two lead screws ensures that the two lead screws move towards each other. The rangefinder can detect the distance between the clamping plate and the mold parts. When the detected distance is zero, the rotation of the dual output shaft motor can be stopped to avoid excessive clamping force damaging the mold parts. The rubber pad reduces the pressure on the mold parts.

[0012] The present invention is further configured such that the top of the mounting plate has a through hole for the connecting column, the top of the mounting plate has a first pin hole, and the top of the drive plate has a second pin hole. The through hole provides space for the vertical movement of the connecting column. After the first pin passes through the second pin hole, it is inserted into the inner cavity of the first pin hole, which can lock the drive plate in the current position and thus fix the position of the second pin, thereby realizing the connection between the mounting plate and the pressure plate.

[0013] The present invention is further configured such that the surface of the connecting column is provided with a pin hole three through which the pin rod two passes, and the inner cavity of the positioning plate is provided with a round hole through which the pin rod two passes.

[0015] The present invention has the following beneficial effects.

[0016] 1. In this utility model, the pressure plate in the elastic support assembly is located above the parts to be assembled. The movable rod and spring can provide a certain elastic deformation capacity, so that the pressure plate can automatically adjust the pressure distribution according to the shape of the part surface, avoiding deformation of the parts due to excessive local pressure. This can ensure the assembly accuracy of the parts, improve the assembly quality of the entire precision mold, and reduce mold failures and production losses caused by assembly quality problems. Different pressure plates can be quickly replaced by the set quick-release assembly to adapt to mold parts of different shapes.

[0017] 2. This utility model's base is used to hold precision mold components. A hydraulic telescopic rod acts as the downward pressing force to press and assemble the components. The hydraulic telescopic rod is connected to an external controller; the downward pressure is controlled by adjusting the amount of hydraulic oil entering. A moving groove provides movement space for the lead screw. A limiting groove and a limiting block work together to limit the clamping plate, preventing it from rotating with the lead screw. A dual-output shaft motor can simultaneously drive two lead screws to rotate synchronously, ensuring consistent power. The clamping plate can clamp and fix the mold components, facilitating the installation of other components. The threaded hole and lead screw work together to move the threaded block, which in turn moves the clamping plate. The threads on the two lead screws are designed in opposite directions, ensuring that the two lead screws move towards each other. A distance measuring instrument can detect the distance between the clamping plate and the mold components. When the detected distance... The dual-output shaft motor can be stopped when the force is zero, avoiding excessive clamping force that could damage the mold components. The rubber pad reduces the pressure on the mold components. The turntable allows for easy and quick rotation of the shaft. The design of the slide and slider makes the pull ring and the shaft a single unit.

The threaded holes used have reversed threads on the surfaces of the two lead screws 22. A rangefinder 26 is fixedly connected to one side of each of the two clamping plates 24. A rubber pad 27 is fixedly connected to one side of each of the two clamping plates 24. A turntable is fixedly connected to the top of the rotating shaft 41. A groove 49 is provided on the surface of the rotating shaft 41. A slider 410 is slidably connected to the inner cavity of the groove 49. The other side of the slider 410 is fixedly connected to the inner wall of the pull ring 45. A through hole 411 is provided on the top of the mounting plate 33 through the connecting post 32. A pin hole 412 is provided on the top of the mounting plate 33. A pin hole 413 is provided on the top of the drive disc 42. A pin hole 414 is provided on the surface of the connecting post 32 through the pin 46. A round hole 46 is provided in the inner cavity of the positioning plate 47 through the pin 46. The pin 46 has a stepped design, and the end that contacts the drive disc 42 is hemispherical.

[0031] Specifically: Base 11 is used to place components of the precision mold; hydraulic telescopic rod 12 serves as the downward pressing force to press and assemble the components; hydraulic telescopic rod 12 is connected to an external controller, and its downward pressure can be controlled by controlling the amount of hydraulic oil entering; moving groove 14 provides movement space for lead screw 22; limiting groove 15 and limiting block 25 cooperate to limit clamping plate 24 to prevent it from rotating with lead screw 22; dual output shaft motor 21 can drive two lead screws 22 to rotate synchronously, ensuring consistent power; clamping plate 24 can clamp and fix mold components, facilitating the installation of other components; threaded hole and lead screw 22 cooperate to drive threaded block 23 to move, which in turn drives clamping plate 24 to move; the threads on the surfaces of the two lead screws 22 are designed in opposite directions, thus ensuring that the two lead screws 22 move towards each other; rangefinder 26 can detect the distance between clamping plate 24 and mold components; when the detected distance is zero, the dual output shaft can be stopped. The rotation of motor 21 avoids excessive clamping force that could damage mold components. Rubber pad 27 reduces the pressure on mold components. The turntable allows for easy and quick rotation of shaft 41. The design of slide groove 49 and slider 410 makes pull ring 45 and shaft 41 a single unit. As shaft 41 rotates, it drives pull ring 45 to rotate as well. Through hole 411 provides space for the vertical movement of connecting post 32. Pin 1 43 is inserted into the inner cavity of pin hole 1 412 after passing through pin hole 2 413, which can lock drive disk 42 in the current position and fix the position of pin 2 46, thus achieving the connection between mounting plate 33 and pressure plate 31. Pin hole 3 414 cooperates with pin 2 46 to fix connecting post 32 to the bottom of mounting plate 33. The opening of the round hole facilitates the left and right movement of pin 2 46. The stepped design of pin 2 46 facilitates the installation of spring 3 48. The hemispherical design of one end ensures the smooth movement of pin 2 46.

[0032] The working principle of this utility model is as follows: the dual-output shaft motor 21 starts, driving two lead screws 22 to rotate. The two lead screws 22 drive two left and right threaded blocks 23 to move towards each other, so that the clamping plate 24 slides smoothly along the limiting groove 15 through the limiting block 25, achieving precise clamping of the workpiece. The rangefinder 26 monitors the clamping distance in real time, and the rubber pad 27 avoids damage to the workpiece surface and ensures clamping stability.

[0033] After the components are clamped, the other components are assembled. Then, the height of the top plate 13 is adjusted by activating the hydraulic telescopic rod 12, so that the pressure plate 31 in the elastic support assembly 3 contacts the top surface of the workpiece. The spring 36 provides elastic cushioning through the movable rod 34 and the guide tube 35 to avoid deformation of the parts caused by rigid contact, while also accommodating workpieces of different heights.

[0034] Pulling the pull ring 45 disengages pin 43 from pin hole 412 at the top of mounting plate 33. At this time, the rotating disc drives the drive disc 42 to rotate clockwise. The eccentric structure of the drive disc 42 causes pin 46 to move outward under the elastic action of spring 48, disengaging from pin hole 414 and releasing the lock on connecting post 32. The pressure plate 31 can then be removed. A suitable pressure plate 31 is then replaced, and the drive disc 42 is rotated counterclockwise. The drive disc 42 presses pin 46 back into the inner cavity of pin hole 414. Simultaneously, spring 44 pushes pin 43 into pin hole 412 at the top of mounting plate 33, locking the rotating disc and thus connecting and fixing mounting plate 33 to pressure plate 31.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described.
