[0002] Medical device processing molds are the basic structures used to manufacture medical device components. They typically consist of multiple templates, guide parts, and support parts, providing support, positioning, and guidance for the forming part of the mold to ensure the precision and quality of the medical device components during processing.
[0003] Medical device processing mold frames use pressure plates and bolts to press parts onto the mold frame. The pressure plates usually have a certain shape and size. The parts are pressed tightly onto the surface of the mold frame by the fixtures, which can ensure the stability and accuracy of the mold frame and parts during the processing, and improve processing precision and efficiency.
[0004] Pressure plates typically have a certain shape and size, but when fixing irregularly shaped medical devices, the pressure plate may not fit the medical device properly, resulting in a small contact area. This can affect the fixing effect on the medical device processing mold, thereby affecting the processing accuracy and quality. Utility Model Content

[0029] Example 1
[0030] This embodiment proposes a mold frame for medical device processing, such as... Figure 1As shown, the workbench 1 is included. A top plate 2 is fixedly installed on the top of the workbench 1. Fixed support blocks 3 are fixedly installed on the top of the top plate 2 and the bottom of the workbench 1. Four support columns are fixedly installed on the bottom of the workbench 1. Reinforcing ribs 6 are fixedly connected between the four support columns to enhance the stability of the support.
[0031] like Figure 2 and Figure 3 As shown, each of the two fixed support blocks 3 is provided with a positioning clamp 4 suitable for small and medium-sized medical devices on one side facing each other. The positioning clamp 4 includes a longitudinal hydraulic push rod 41. An I-beam frame 42 is fixedly installed at the end of the longitudinal hydraulic push rod 41. The longitudinal hydraulic push rod 41 is fixedly installed on one side facing each other of the two fixed support blocks 3. The I-beam frame 42 adopts a U-shaped structure. Multiple pressure plates 44 that contact the medical devices are slidably connected in the opening of the I-beam frame 42. The multiple pressure plates 44 are distributed in a straight line and are equidistant along the I-beam frame 42 and are parallel to each other.
[0032] A support spring 45 is fixedly installed on the side of the I-beam frame 42. The other end of the support spring 45 is fixedly connected to the I-beam frame 42 and contacts the medical device through the pressure plate 44. The support spring 45 supports the pressure plate 44 to limit its position. Initially, multiple pressure plates 44 are on the same straight line.
[0033] Multiple slides 43 are provided in the opening of the I-beam frame 42. The pressure plate 44 slides in the slides 43. The longitudinal hydraulic push rod 41 extends to clamp the medical device by the pressure plate 44 located above and below the medical device. After the pressure plate 44 contacts the medical device, it slides along the slides 43 to adapt to the shape of the medical device.
[0034] like Figure 3 As shown, a positioning clamp 47 is slidably connected to the inside of the I-beam frame 42. The positioning clamp 47 is located on the end extension line of the pressure plate 44. A transverse hydraulic push rod 46 is fixedly installed inside the I-beam frame 42. The end of the transverse hydraulic push rod 46 is fixedly connected to the positioning clamp 47. Initially, there is a gap between the positioning clamp 47 and the pressure plate 44 to prevent the positioning clamp 47 from obstructing the sliding of the pressure plate 44.
[0035] After multiple pressure plates 44 are attached to the medical device, the positioning clamps 47 are pushed by the transverse hydraulic push rod 46 so that the positioning clamps 47 at both ends of the pressure plate 44 clamp the pressure plate 44 to fix the position of the pressure plate 44.
[0036] Storage slots 48 are provided on the top of the workbench 1 and the bottom of the top plate 2. The I-beam frame 42 is located in the storage slot 48. The pressure plates 44 in the two positioning clamps 4 are flush with the bottom of the workbench 1 and the bottom of the top plate 2, respectively, to prevent medical equipment from being obstructed by the positioning clamps 4 when placed on the workbench 1.
[0037] In this embodiment, the longitudinal hydraulic push rod 41 extends to move multiple pressure plates 44 toward the medical device. After the pressure plate 44 contacts the medical device, it slides along the slide rail 43 to adapt to the shape of the medical device. The transverse hydraulic push rod 46 extends to clamp the pressure plate 44 with the positioning clamp 47 to fix the position of the pressure plate 44. The multiple pressure plates 44 are positioned after being adapted to the medical device to adapt to irregularly shaped medical devices, increase the contact area, and improve the fixing effect.
[0038] Example 2
[0039] Based on Example 1, this example proposes a mold frame for medical device processing, such as... Figure 4 As shown, a pressure assembly 5 is provided between the pressure plate 44 and the positioning clamp 47. The pressure assembly 5 includes a biting strip 51 and a rubber 52. The biting strip 51 is fixedly installed on the side of the positioning clamp 47, and the rubber 52 is fixedly installed at both ends of the pressure plate 44. The biting strip 51 is in contact with the rubber 52.
[0040] The lateral hydraulic push rod 46 extends to move the positioning clamp 47 toward the pressure plate 44, so that the biting strip 51 comes into contact with the rubber 52. Since the rubber 52 is elastic, the biting strip 51 squeezes the rubber 52 to deform it. After the rubber 52 is deformed, it forms a groove that fits the biting strip 51, so that the rubber 52 is suspended on the biting strip 51, thereby increasing the friction between the positioning clamp 47 and the pressure plate 44 and preventing the pressure plate 44 from slipping.
[0041] Multiple bite strips 51 are provided, and the multiple bite strips 51 are distributed at equal intervals in a vertical line along the positioning clamp 47. The bite strips 51 are parallel to the horizontal plane. The bite force is further increased by contacting the rubber 52 through the multiple bite strips 51. Since this application is used for small and medium-sized medical devices, the downward pressure on the pressure plate 44 will not be too large.
[0042] In this embodiment, the rubber 52 is deformed by the gripping strip 51. After the rubber 52 is deformed, it forms a groove that matches the gripping strip 51. Multiple gripping strips 51 are used to increase the contact area with the rubber 52, so as to improve the stability of the pressure plate 44 and prevent the pressure plate 44 from slipping.
[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
