Description

Technical Field

[0001] This utility model relates to the field of medical parts processing technology, specifically to a clamping mold for the production of medical parts. Background Technology

[0002] In today's rapidly developing medical technology landscape, the demand for various high-precision, high-performance medical components is increasing daily, and their quality directly affects the reliability of medical equipment and the life and health safety of patients. Medical components cover a wide range, from tiny implantable sensor parts to complex surgical instrument assemblies. These components not only have strict biocompatibility requirements for materials, but also have extremely high standards in terms of dimensional accuracy, surface quality, and shape complexity.

[0003] In the manufacturing process of medical components, clamping dies play an irreplaceable role as key process equipment. The main function of clamping dies is to provide stable and precise positioning and reliable clamping force during part machining, ensuring that the parts remain in a fixed position under the action of external forces such as cutting forces and gravity, thereby guaranteeing machining accuracy and surface quality. However, traditional clamping dies have gradually revealed many limitations when dealing with the production of medical components.

[0004] Patent application CN202420842885.9 discloses a clamping mold for medical component production, belonging to the field of medical component processing technology. Its key technical features include a lower mold housing with a placement plate movably connected inside. Fixed plates are fixedly connected to the front and rear sides of the top of the placement plate. A clamping assembly is provided between opposite sides of the two fixed plates. By setting the placement plate, medical components can be placed on top of it. By setting the clamping assembly, when the screw rotates, it drives the threaded sleeve to move on the surface of the screw. The threaded sleeve drives the support plate and the first clamping plate to move together. The two first clamping plates can clamp and limit the front and rear sides of the medical component, making it suitable for medical components of different sizes. Furthermore, the rotatable connection between adjacent first clamping plates increases the clamping force for medical components with uneven surfaces, further improving the clamping effect.

[0005] However, this patent cannot achieve rapid clamping when holding medical parts, and manual segmented clamping is still required, which greatly increases the labor time.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this utility model is to provide a clamping mold for the production of medical parts that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted: A clamping mold for manufacturing medical parts includes: a lower mold and a clamping mechanism for clamping the medical parts; The clamping mechanism includes: a support base fixedly mounted on the lower mold, a mounting base fixedly mounted on the support base, a gripper hinged to the mounting base, a first hinge rod hinged to the gripper, a rotating plate hinged to the first hinge rod, and a cylinder for driving the rotating plate to rotate; the cylinder is fixedly mounted on the lower mold; the piston rod of the cylinder is hinged to the rotating plate; and the rotating plate is rotatably mounted on the support base.

[0009] Furthermore, the rotating plate is a rotating plate with multiple protrusions, and the hinge rod and the cylinder piston rod are respectively rotatably mounted on different protruding sides of the rotating plate.

[0010] Furthermore, the grippers are provided in two sets and are located on both sides of the mounting plate.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0018] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0019] like Figures 1 to 3 As shown, the present invention provides a clamping mold for the production of medical parts, comprising: a lower mold 1 and a clamping mechanism 2 for clamping the medical parts; The clamping mechanism 2 includes: a support base 21 fixedly mounted on the lower mold 1, a mounting base 22 fixedly mounted on the support base 21, a gripper 23 hinged to the mounting base 22, a hinge rod 24 hinged to the gripper 23, a rotating plate 25 hinged to the hinge rod 24, and a cylinder 6 for driving the rotating plate 25 to rotate; the cylinder 6 is fixedly mounted on the lower mold 1; the piston rod of the cylinder 6 is hinged to the rotating plate 25; and the rotating plate is rotatably mounted on the support base 21.

[0020] When performing operations on precision medical parts, the part can be placed on the mounting base 22. At this time, the drive cylinder 6 is activated, causing its piston rod to extend linearly along the axial direction. This extension of the piston rod drives the rotating plate 25, connected to it, to rotate around a preset rotation axis on the support base 21. As the rotating plate 25 rotates, the hinge rod 24, hinged to the rotating plate 25, will generate a corresponding linkage displacement, thereby driving the gripper 23 to rotate around the hinge fulcrum on the mounting base 22. Ultimately, this achieves stable clamping and precise fixation of the medical part placed on the mounting base 22 by the gripper 23.

[0021] Two sets of grippers 23 are provided and are located on both sides of the mounting plate; the rotating plate 25 is a multi-protruding rotating plate 25, and the hinge rod 24 and the piston rod of the cylinder 6 are respectively rotatably mounted on different protruding sides of the rotating plate 25. Because there are two sets of grippers 23 on both sides of the mounting plate, when the cylinder 6 pushes the rotating plate 25 to rotate, its grippers 23 can symmetrically and firmly clamp the medical parts placed on the mounting plate.

[0022] The rotating plate 25 is also hinged to a second hinge rod 28; a top rod 29 is hinged to the other end of the second hinge rod 28; the top rod 29 is inserted into the mounting plate.

[0023] It should be emphasized that when the rotating plate 25 is driven to rotate, the hinge rod 28, which is hinged to the rotating plate 25, will generate a linkage effect, thereby driving the top rod 29 to make a linear lifting motion along the guide path set by the mounting plate.

[0024] Specifically, during the forward rotation of the rotating plate 25 driven by the output power of cylinder 6, on the one hand, hinge rod 24, based on its hinged connection with the rotating plate 25 and the gripper 23, applies a driving force to the gripper 23, causing it to rotate around its hinge fulcrum, thus changing the gripper 23's original position and releasing its gripping effect on the medical part. On the other hand, hinge rod 28 simultaneously exerts force to push the ejector rod 29 upward. As the ejector rod 29 continues to move upward, it applies an upward lifting force to the medical part that has completed the clamping process, assisting in the demolding operation of the medical part. This design effectively avoids the problem of mold jamming caused by the adhesion between the part and the mold during subsequent processing of the medical part, ensuring the smoothness and stability of the processing flow.

[0025] Conversely, when the rotating plate 25 rotates in the opposite direction under the action of the reverse driving force, the gripper 23 will move towards the medical part based on the linkage mechanism between the components, and re-secure the medical part; at the same time, the top rod 29 will move downward in a straight line along the guide path of the mounting plate under the reverse drive of the hinge rod 28, and return to the initial position, preparing for subsequent processing operations.

[0026] The mounting plate is also provided with a side clamping assembly 3; The side clamping assembly 3 includes: a side clamping block 31 slidably mounted on the mounting plate, a hinge rod 32 hinged to the side clamping block 31, and the hinge rod 32 hinged to the top rod 29; the side clamping block 31 is symmetrically provided in two sets.

[0027] As the top rod 29 moves downward, the hinge rod 32, which is hinged to the top rod 29, simultaneously pulls the side clamping block 31, which is slidably mounted on the mounting plate, closer to the medical part to be fixed, thereby laterally fixing the medical part.

[0028] Working principle: When medical parts need to be operated, cylinder 6 drives rotating plate 25 to rotate. On the one hand, the rotation of rotating plate 25 drives gripper 23 to vertically clamp the medical parts. On the other hand, when picking up the parts, it can drive push rod 29 to lift and pick up the medical parts. When push rod 29 moves downward, it can drive side clamping block 31 to approach the medical parts and mechanically clamp them laterally, thereby achieving multi-directional and rapid clamping and fixing.

[0029] All standard parts used in this utility model can be purchased from the market, and irregularly shaped parts can be customized according to the description and drawings. The specific connection methods for each part all employ conventional methods such as bolts, rivets, and welding, which are mature technologies in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, and the circuit connections also use conventional connection methods in the prior art, which will not be detailed here. Contents not described in detail in this specification belong to prior art known to those skilled in the art.
