Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically a high-efficiency tooling and fixture for degreasing ornaments of MIM injection molded products. Background Technology

[0002] MIM (Metal Injection Molding) degreasing parts refer to products manufactured using metal injection molding. In the degreasing process, special tools or devices are used to support, fix, or assist the degreasing process. Metal injection molding is an advanced manufacturing technology that combines plastic injection molding technology with powder metallurgy. It is mainly used to produce high-precision, complex-shaped metal parts and is widely used in electronics, medical, automotive, aerospace and other fields.

[0003] Tooling fixtures are specialized process equipment used in industrial production to fix, position, support workpieces, or guide tools. They are important auxiliary tools in the field of mechanical manufacturing. Their core function is to improve machining accuracy, efficiency, safety, and standardization. They are widely used in production processes such as machining, welding, assembly, testing, and heat treatment. Their purpose is to ensure that workpieces maintain accurate position and posture during processing, avoiding dimensional deviations or quality defects caused by movement or shaking. They replace manual support or complex adjustments, reducing the physical exertion of operators, and are especially suitable for heavy or complex workpieces.

[0004] Existing technology publication CN221020673U patent document provides a high-efficiency tooling fixture. This high-efficiency tooling fixture is equipped with two clamping plates and a top plate. By rotating the knob on the top, the clamping plates can be moved horizontally via a lead screw. The two sides of the workpiece contact the clamping plates to achieve clamping and positioning on both sides. After processing, cylinder one moves the clamping plates to both sides, and cylinder two moves the top plate downward to remove the workpiece. When clamping the same workpiece in the future, cylinder one and cylinder two can reset the clamping plates and the top plate to complete the clamping and positioning operation. Compared with traditional tooling fixtures, when clamping the same workpiece, there is no need to manually adjust the fixture, resulting in higher work efficiency.

[0005] While the aforementioned prior art, with its high-efficiency tooling fixture, allows the lead screw to move the clamping plate and top plate horizontally by rotating a knob, thereby clamping and fixing the workpiece on both sides without requiring manual adjustment and improving work efficiency, this patented technology can only clamp and fix the workpiece on both sides. When processing the sides of the workpiece, it is difficult to fix the top, which requires the use of other devices, greatly reducing its practicality. Therefore, we need a high-efficiency tooling fixture for degreased ornaments of MIM injection molded products. Utility Model Content

[0006] The purpose of this utility model is to provide a high-efficiency tooling fixture for degreased ornaments of MIM injection molded products, in order to solve the problem that the tooling fixture in the patented technology mentioned in the background art can only clamp and fix the two sides of the workpiece when it is used. When the two sides of the workpiece need to be processed, it is difficult to fix the top of the workpiece, which requires the use of other devices to assist, greatly reducing its practicality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency tooling fixture for degreased ornaments of MIM injection molded products includes a worktable, a storage compartment on the front of the worktable, a pressing component on the top of the worktable, and table legs fixedly connected to the bottom of the worktable, with a support component provided on one side of the table legs. The pressing assembly includes a rocker arm, a rotating rod is provided on one side of the rocker arm, and a first bevel gear set is rotatably connected to the outer wall of the rotating rod. A first threaded rod is provided at the bottom of the first bevel gear set. A second bevel gear set is rotatably connected to the outer wall of the rotating rod, and a second threaded rod is provided at the bottom of the second bevel gear set. A lifting block is threadedly connected to the outer wall of the second threaded rod, and a pressing plate is fixedly connected to the front of the lifting block. The support assembly includes a fixing block, a hydraulic cylinder is provided at the bottom of the fixing block, and a spring damper is installed inside the hydraulic cylinder. A limit plate is provided at the bottom of the spring damper, and a sliding rod is fixedly connected to the bottom of the limit plate. The bottom of the sliding rod is equipped with a base.

[0008] Preferably, the top of the workbench is equipped with a left and right clamping mechanism.

[0009] Preferably, the rocker arm forms a rotating structure with the first bevel gear set via a rotating rod, and one end of the rotating rod passes through the first bevel gear set. The rotating rod forms a rotating structure with the first threaded rod via the first bevel gear set.

[0010] Preferably, the rotating rod forms a rotating structure with the second bevel gear set and the second threaded rod, and the second bevel gear set is arranged in opposite directions to the first bevel gear set.

[0011] Preferably, the second threaded rod forms a lifting structure with the lifting block and the pressing plate, and the shape and size of the outer wall of the second threaded rod match the shape and size of the inner wall of the lifting block.

[0012] Preferably, the fixing block forms a lifting structure with the base via a hydraulic cylinder, and the hydraulic cylinder is installed between the fixing block and the base.

[0013] Preferably, the hydraulic cylinder forms an elastic structure with a spring damper and a limiting plate, and the limiting plate is installed inside the hydraulic cylinder. The hydraulic cylinder forms an elastic structure with a slide rod through a spring damper.

[0014] Compared with the prior art, the beneficial effects of this utility model are: a high-efficiency tooling fixture for degreasing ornaments of MIM injection molded products. Firstly, this utility model includes a rocker arm, a rotating rod, a first bevel gear set, a first threaded rod, a second bevel gear set, a second threaded rod, lifting blocks, and a pressing plate. Rotating the rocker arm drives the rotating rod to rotate, causing the first and second bevel gear sets to rotate at the same speed. The first and second bevel gear sets in this assembly transmit power, enabling the first and second threaded rods to rotate at the same speed. This, in turn, drives the two lifting blocks to rise and fall at the same speed, thus raising and lowering the pressing plate. The descent of the pressing plate presses and fixes the workpiece on the worktable. This assembly effectively fixes the top of the workpiece, facilitating processing of both sides and greatly increasing its practicality.

[0015] Secondly, this utility model includes a fixed block, a hydraulic cylinder, a spring damper, a limiting plate, a sliding rod, and a base. The workbench can be moved to the desired position by the casters at the bottom of the table legs, and the extension and retraction of the hydraulic cylinder can drive the base to rise and fall, thus providing stable support for the workbench and preventing it from moving arbitrarily. The spring damper can reduce vibrations caused by processing, allowing the sliding rod to slide within the hydraulic cylinder for cushioning. This component provides stable support for the workbench and also has a certain vibration reduction effect. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A high-efficiency tooling fixture for degreased ornaments of MIM injection molded products includes a worktable 1, a storage compartment 2 on the front of the worktable 1, a pressing component 3 installed on the top of the worktable 1, a table leg 5 fixedly connected to the bottom of the worktable 1, and a support component 6 provided on one side of the table leg 5. The pressing assembly 3 includes a rocker arm 301, a rotating rod 302 is provided on one side of the rocker arm 301, and a first bevel gear set 303 is rotatably connected to the outer wall of the rotating rod 302. A first threaded rod 304 is provided at the bottom of the first bevel gear set 303. A second bevel gear set 305 is rotatably connected to the outer wall of the rotating rod 302, and a second threaded rod 306 is provided at the bottom of the second bevel gear set 305. A lifting block 307 is threadedly connected to the outer wall of the second threaded rod 306, and a pressing plate 308 is fixedly connected to the front of the lifting block 307. The support assembly 6 includes a fixing block 601, a hydraulic cylinder 602 is provided at the bottom of the fixing block 601, and a spring damper 603 is installed inside the hydraulic cylinder 602. A limit plate 604 is provided at the bottom of the spring damper 603, and a slide rod 605 is fixedly connected to the bottom of the limit plate 604. A base 606 is installed at the bottom of the slide rod 605.

[0020] Through the above technical solution, by rotating the rocker arm 301, the rotating rod 302 can be driven to rotate. When the rotating rod 302 rotates, the first bevel gear set 303 and the second bevel gear set 305 can rotate at the same speed. The first bevel gear set 303 and the second bevel gear set 305 play the role of transmitting power in this component, which can make the first threaded rod 304 and the second threaded rod 306 rotate at the same speed. This can drive the two lifting blocks 307 to rise and fall at the same speed, thereby driving the pressing plate 308 to rise and fall. The lowering of the pressing plate 308 can press and fix the workpiece on the worktable 1. The setting of this component can fix the top of the workpiece, which facilitates the processing of the two sides of the workpiece and greatly increases its practicality.

[0021] Specifically, the top of the workbench 1 is equipped with left and right clamping mechanisms 4.

[0022] Through the above technical solution, the left and right clamping mechanism 4 drives the clamping plate to move relative to each other by driving the cylinder, thereby achieving the effect of clamping and fixing the workpiece from the left and right.

[0023] Specifically, the rocker arm 301 forms a rotating structure with the first bevel gear set 303 via the rotating rod 302, and one end of the rotating rod 302 is set through the first bevel gear set 303. The rotating rod 302 forms a rotating structure with the first threaded rod 304 via the first bevel gear set 303.

[0024] Through the above technical solution, by rotating the rocker arm 301, the rotating rod 302 can be driven to rotate. When the rotating rod 302 rotates, the first bevel gear set 303 can be rotated, thereby driving the first threaded rod 304 to rotate, thus playing the role of transmitting power.

[0025] Specifically, the rotating rod 302 forms a rotating structure with the second bevel gear set 305 and the second threaded rod 306, and the second bevel gear set 305 is arranged opposite to the first bevel gear set 303.

[0026] Through the above technical solution, while the rotating rod 302 rotates, the second bevel gear set 305 can also rotate, thereby driving the second threaded rod 306 to rotate synchronously. The second bevel gear set 305 and the second threaded rod 306 rotate in the opposite direction to the first bevel gear set 303 and the first threaded rod 304, thus enabling them to maintain the same speed.

[0027] Specifically, the second threaded rod 306 forms a lifting structure with the lifting block 307 and the pressing plate 308, and the shape and size of the outer wall of the second threaded rod 306 match the shape and size of the inner wall of the lifting block 307.

[0028] Through the above technical solution, by rotating the first threaded rod 304 and the second threaded rod 306 at the same speed, the two lifting blocks 307 can be raised and lowered at the same speed, thereby keeping the lifting and lowering of the pressing plate 308 balanced, thus playing a role in pressing and fixing the workpiece.

[0029] Specifically, the fixed block 601 forms a lifting structure with the base 606 via the hydraulic cylinder 602, and the hydraulic cylinder 602 is installed between the fixed block 601 and the base 606.

[0030] Through the above technical solution, the extension and retraction of the hydraulic cylinder 602 can drive the base 606 to rise and fall, thereby providing stable support for the worktable 1 and preventing it from moving arbitrarily.

[0031] Specifically, the hydraulic cylinder 602 forms an elastic structure with the limiting plate 604 via the spring damper 603, and the limiting plate 604 is installed inside the hydraulic cylinder 602. The hydraulic cylinder 602 forms an elastic structure with the slide rod 605 via the spring damper 603.

[0032] Through the above technical solution, the spring damper 603 can play a certain vibration reduction effect when the worktable 1 vibrates due to processing, so that the slide rod 605 slides in the hydraulic cylinder 602 to buffer.

[0033] Working Principle: When using this high-efficiency tooling fixture for degreased MIM injection molded products, the worktable 1 is first moved to the desired position manually. Then, the hydraulic cylinder 602 is activated, which extends and retracts the base 606 to support the worktable 1. The spring damper 603 and slide bar 605 inside the hydraulic cylinder 602 provide a certain vibration reduction effect for the worktable 1. After the worktable 1 is supported, the workpiece can be placed on the worktable 1. Then, the rocker arm 301 is turned manually, which drives the rotating rod 302 to rotate. When the rotating rod 302 rotates, the first bevel gear set 303 and the second bevel gear set 305 rotate at the same speed, thereby causing the first threaded rod 304 and the second threaded rod 306 to rotate at the same speed. Then, through the connection of the lifting block 307, the pressing plate 308 is driven to descend, thereby pressing the workpiece. This completes the entire work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] 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 defined by the appended claims and their equivalents.
