Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0036] The following is combined Figures 2 to 5 This application describes a mold assembly for producing surgical scalpel handles.

[0037] A mold assembly for producing scalpel handles according to an embodiment of this application includes: a device body 100, a slider insert 200, and a blade insert component 300. The device body 100 is provided with a mounting hole 110. The slider insert 200 is detachably mounted in the mounting hole 110 and is provided with a handle head injection cavity 210 and a blade insert mounting cavity 220. The handle head injection cavity 210 and the blade insert mounting cavity 220 are arranged opposite to each other. The slider insert 200 is provided with a through hole 230 that connects the handle head injection cavity 210 and the blade insert mounting cavity 220. The blade insert component 300 is detachably mounted in the blade insert mounting cavity 220, and at least partially passes through the through hole 230 and extends into the handle head injection cavity 210.

[0038] According to the embodiments of this application, the mold assembly for producing scalpel handles, through the detachable slider insert 200 and the detachable insert component 300, allows for quick disassembly and timely replacement when the insert component 300 needs to be replaced, reducing the replacement cost of the insert component 300, thereby reducing the manufacturing cost of the scalpel handle and improving production efficiency.

[0039] The slider insert 200 is detachably mounted in the mounting hole 110 of the device body 100, and the insert component 300 is detachably mounted in the insert mounting cavity 220. This modularity of the mold assembly simplifies and expedites the replacement of the insert component 300, reducing replacement costs. The insert component 300 at least partially passes through the mounting hole 230 and extends into the injection molding cavity 210 of the scalpel handle head. The shape and size of the insert component 300 match the tail of the scalpel blade, forming a scalpel handle connection portion adapted to the tail of the blade during injection molding. Because the insert component 300 can be replaced individually without replacing the entire mold assembly, the manufacturing cost of the scalpel handle is significantly reduced. By replacing insert components 300 of different shapes and sizes, different types of scalpel blade tails can be accommodated, meeting diverse production needs.

[0040] According to one embodiment of this application, the insert component 300 includes an insert portion 310 and a limiting portion 320. The limiting portion 320 is connected to the insert portion 310. The insert portion 310 passes through the insertion hole 230 and extends into the injection cavity 210 of the handle head. The cross-sectional area of ​​the limiting portion 320 is larger than the opening area of ​​the insertion hole 230.

[0041] Understandably, the insert part 310 matches the tail of the scalpel blade. During injection molding, the insert part 310 forms a handle connection portion adapted to the tail of the blade. The limiting part 320 is connected to the insert part 310, and its main function is to prevent the insert part 300 from being ejected or displaced by the injection molding material during the injection molding process. The cross-sectional area of ​​the limiting part 320 is designed to be larger than the opening area of ​​the through hole 230. Thus, when the insert part 300 is installed into the slider insert 200, the limiting part 320 will be locked at the opening of the through hole 230, thereby stabilizing the insert part 300.

[0042] This application does not restrict the specific shape of the limiting part 320, as long as the cross-sectional area of ​​the limiting part 320 is larger than the opening area of ​​the through hole 230.

[0043] According to one embodiment of this application, the insert part 310 includes an insert head 311, which is located in the injection cavity 210 of the handle head. The cross-sectional shape of the insert head 311 is one of the following: round hole, square hole, rectangular hole, elliptical hole, triangle, and hexagon.

[0044] Understandably, the insert head 311 is the part of the insert part 310 that directly contacts and fits the tail of the scalpel blade. Depending on the different shapes and sizes of the scalpel blade tail, the insert head 311 is designed with various cross-sectional shapes, including but not limited to: round holes, square holes, rectangular holes, elliptical holes, triangular holes, and hexagonal holes. This diverse design allows the insert component 300 to fit more types of scalpel blade tails, meeting the diverse needs of the medical device manufacturing field.

[0045] Of course, the insert head 311 can also be set to an irregular shape; no specific restrictions are imposed here.

[0046] According to one embodiment of this application, the limiting part 320 is provided with a first anti-rotation part 321, and the insert mounting cavity 220 is provided with a first anti-rotation structure corresponding to the first anti-rotation part 321. The first anti-rotation part 321 is adapted to be rotated and limited with the first anti-rotation structure.

[0047] It is understood that the first anti-rotation part 321 is used to cooperate with the first anti-rotation structure in the insert mounting cavity 220 to achieve the function of rotation limit and prevent the insert component 300 from rotating during injection molding. The shape and size of the first anti-rotation part 321 can be designed according to actual needs. Common shapes include but are not limited to: plane, protrusion, groove, etc., and the first anti-rotation structure is set to correspond to the shape and size of the first anti-rotation part 321.

[0048] During the assembly of the mold assembly, the limiting part 320 of the insert component 300 is installed into the insert mounting cavity 220 of the slider insert 200. At this time, the first anti-rotation part 321 contacts and fits tightly with the first anti-rotation structure, thereby preventing the insert component 300 from rotating during subsequent injection molding. This design not only improves the stability of the mold assembly but also ensures the accurate connection between the scalpel handle and the blade tail.

[0049] According to one embodiment of this application, the slider insert 200 is provided with a second anti-rotation part 201, and the mounting hole 110 is provided with a second anti-rotation structure corresponding to the second anti-rotation part 201. The second anti-rotation part 201 is adapted to be rotated and limited with the second anti-rotation part 201.

[0050] It is understood that the second anti-rotation part 201 is used to cooperate with the second anti-rotation structure in the mounting hole 110 to achieve the function of rotation limit and prevent the insert component 300 from rotating during injection molding. The shape and size of the second anti-rotation part 201 can be designed according to actual needs, and common shapes include but are not limited to: plane, protrusion, groove, etc. The second anti-rotation structure is set corresponding to the second anti-rotation part 201.

[0051] According to one embodiment of this application, a connecting member 400 is included, which is connected to the device body 100. The tool holder head injection cavity 210 is located on the side away from the connecting member 400, and the tool insert mounting cavity 220 is located on the side close to the connecting member 400.

[0052] The main body 100 of the device is detachably mounted on the connecting part 400, which can protect and support the insert part 300.

[0053] During the assembly of the mold assembly, the slider insert 200 is first installed into the mounting hole 110 of the device body 100, ensuring that the second anti-rotation part 201 fits tightly with the second anti-rotation structure. Then, the insert component 300 is installed into the insert mounting cavity 220 of the slider insert 200, ensuring that the first anti-rotation part 321 fits tightly with the first anti-rotation structure. Finally, the entire device body 100 is installed into the connecting component 400, ready for injection molding.

[0054] During injection molding, the injection material is injected into the injection cavity 210 of the tool holder head. Due to the rotation limiting function of the first anti-rotation part 321 and the second anti-rotation part 201, the tool insert 300 and the slider insert 200 can remain stable, preventing rotation or displacement. After injection molding is completed, the mold assembly can be easily disassembled and cleaned for the next round of production.

[0055] According to one embodiment of this application, the device body 100 is provided with a first guide positioning component 120, and the connecting component 400 is provided with a second guide positioning component corresponding to the first guide positioning component 120. The assembly direction of the first guide positioning component 120 and the second guide positioning component is the same as the assembly direction of the device body 100 and the connecting component 400.

[0056] Understandably, the first guide positioning component 120 is used to cooperate with the second guide positioning component on the connecting component 400 to realize the guiding and positioning functions of the mold assembly. The assembly direction of the first guide positioning component 120 and the second guide positioning component is the same as the assembly direction of the device body 100 and the connecting component 400, ensuring the accuracy and stability of the mold assembly during the assembly process.

[0057] The first guide positioning component 120 can be a positioning protrusion or a positioning groove; no specific limitation is made here.

[0058] According to one embodiment of this application, the connecting component 400 is provided with a slope 410, which is used to position the device body 100.

[0059] Understandably, the sloping surface 410 helps with the positioning and stability of the mold components during the injection molding process, preventing product misalignment or non-concentricity.

[0060] According to one embodiment of this application, the connecting component 400 and the device body 100 are fixedly connected by a fastener 500, and the assembly direction of the fastener 500 is the same as the assembly direction of the device body 100 and the connecting component 400.

[0061] Fastener 500 is used to securely connect connecting component 400 and device body 100. In this embodiment, the assembly direction of fastener 500 is the same as the assembly direction of device body 100 and connecting component 400. This design allows fastener 500 to smoothly pass through the assembly holes of connecting component 400 and the assembly slots of device body 100 during assembly, thereby simplifying the assembly process and improving assembly efficiency. Simultaneously, because the assembly direction of fastener 500 is consistent with the assembly direction, it also prevents fastener 500 from loosening or being damaged due to uneven force during assembly.

[0062] According to one embodiment of this application, the device body 100 is provided with a plurality of mounting holes 110, and a plurality of slider inserts 200 are detachably mounted in the mounting holes 110. Each slider insert 200 is provided with a cutting tool component 300 of the same shape or a cutting tool component 300 of a different shape.

[0063] In this embodiment, the main body 100 of the device is provided with a plurality of mounting holes 110, the number and position of which can be customized according to specific needs. Each mounting hole 110 can be detachably mounted with a slider insert 200, so slider inserts 200 of different shapes and sizes can be selected for installation as needed. In addition, each slider insert 200 can be equipped with insert components 300 of the same or different shapes to adapt to the production needs of parts of different shapes and sizes.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
