Description

Technical Field

[0001] This application relates to the field of molds, and more specifically, to a mold for forming a medical needle box. Background Technology

[0002] In hospital operating rooms or during emergency procedures, various instruments are needed, such as needles, scalpels, and syringes. After use, these surgical instruments are usually placed directly in an instrument case and collected and counted after the surgery.

[0003] Medical needle boxes are manufactured using injection molding. For example, a medical reagent kit injection mold disclosed in Chinese patent application number 202420990708.5 allows for the adjustment of the upper limit member of the mold head. Once the mold head is inserted into the mold cavity, the insertion depth can be adjusted, resulting in variable specifications for the produced medical reagent kits. This allows for customization of the kits to suit different applications. However, this molding process involves directly injecting molten material into the mold cavity through the injection port. Due to the large size of the medical needle box, it takes time to fill the mold cavity, increasing the likelihood of air bubbles forming within the mold cavity and affecting the quality of the molded medical needle box. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a medical needle box molding mold, which aims to improve the problem that due to the large volume of the medical needle box, it takes a period of time to fill the mold groove with raw materials during injection molding, which makes it easier for air bubbles to form in the mold groove during the injection molding process, thus affecting the molding quality of the medical needle box.

[0005] This application provides a medical needle box molding die, including a lower die and an upper die.

[0006] The upper mold and the lower mold are provided on the lower mold. The upper mold is provided with an injection port. The lower mold is provided with a mold groove. The upper mold is located directly above the mold groove and is provided with a flow guide plate. The flow guide plate is located inside the mold groove and has several interconnected flow guide grooves.

[0007] In one specific implementation, each of the drainage channels is crisscrossed on the drainage plate, and the outer end of each of the drainage channels is open.

[0008] In one specific implementation, the upper mold is provided with a shaping plate above the flow guide plate, and the shaping plate is in contact with the flow guide plate.

[0009] In one specific implementation, the lower surface of the shaping plate is provided with a clearance groove that mates with each of the drainage grooves.

[0010] In one specific implementation, a first hook and a second hook are respectively installed on both sides of the lower mold and the upper mold, and a connector is provided on both the first hook and the second hook.

[0011] In one specific implementation, the connector includes a tension spring, one end of which is rotatably connected to the first lug, and the other end of which is hung on the second lug.

[0012] In one specific implementation, a mounting block is rotatably connected to the first lug, and one end of the tension spring is connected to the mounting block.

[0013] In one specific implementation, the injection port is provided with an injection channel, which is connected to one of the drainage grooves.

[0014] Beneficial effects: By setting several drainage grooves on the drainage plate, the raw material in a molten state can be evenly and comprehensively injected into the mold groove when it is injected into the mold groove through the injection port, preventing the generation of air bubbles, and making the molded medical needle box of better quality and more beautiful.

[0023] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0024] Please see Figures 1-6 This application provides a medical needle box molding die, including a lower die 1 and an upper die 2.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The system consists of a lower mold 1 and an upper mold 2 mounted on the lower mold 1. The upper mold 2 has an injection port 6, and the lower mold 1 has a mold groove 3. A flow guide plate 4 is positioned directly above the upper mold 2 and inside the mold groove 3. The flow guide plate 4 has several interconnected flow channels 41. During injection molding of the medical needle box, the raw material is injected into the mold groove 3 through the injection port 6. Before entering the mold groove 3, the raw material flows through the injection channel 61 into the flow channels 41 of the flow guide plate 4. The raw material then flows into the mold groove 3 through each flow channel 41, thus achieving the injection molding of the medical needle box. After the raw material cools, the molded product is formed. The presence of several flow channels 41 on the flow guide plate 4 ensures that the molten raw material is evenly and comprehensively injected into the mold groove 3 when injected through the injection port 6, preventing air bubbles and resulting in a higher quality and more aesthetically pleasing finished medical needle box.

[0026] In this embodiment, each flow channel 41 is crisscrossed on the flow channel plate 4, and the outer end of each flow channel 41 is open. The crisscrossing flow channels 41 allow the raw material to flow more evenly and comprehensively into the mold channel 3.

[0027] In the specific configuration, the upper mold 2 is positioned above the flow guide plate 4, and a shaping plate 5 is installed thereon, which contacts the flow guide plate 4. The lower surface of the shaping plate 5 has a relief groove 51 that mates with each flow guide groove 41. The relief groove 51 on the shaping plate 5 effectively limits the flow of raw material within each flow guide groove 41, preventing backflow.

[0028] In this embodiment, a first lug 7 and a second lug 9 are respectively installed on both sides of the lower mold 1 and the upper mold 2. A connecting member 8 is provided on both the first lug 7 and the second lug 9. The connecting member 8 includes a tension spring 81, one end of which is rotatably connected to the first lug 7, and the other end of which is hung on the second lug 9. A mounting block 82 is rotatably connected to the first lug 7, and one end of the tension spring 81 is connected to the mounting block 82. When the upper mold 2 is closed on the lower mold 1, rotating the tension spring 81 so that its other end is hung on the second lug 9 applies pressure to the lower mold 1 and the upper mold 2, making the upper mold 2 more stable when closed on the lower mold 1 and improving the medical molding effect.

[0029] In a specific configuration, the injection port 6 is equipped with an injection channel 61, which is connected to a drainage groove 41. Raw materials are injected into the mold through the injection channel 61.

[0030] The working principle of this medical needle box molding die is as follows: During injection molding of the medical needle box, the raw material is injected into the mold groove 3 through the injection port 6. Before entering the mold groove 3, the raw material flows into the drainage groove 41 of the drainage plate 4 through the injection channel 61. At this time, the raw material flows into the mold groove 3 through each drainage groove 41, realizing the injection molding of the medical needle box. After the raw material cools, it is formed. By setting several drainage grooves 41 on the drainage plate 4, the raw material in a molten state can be evenly and comprehensively injected into the mold groove 3 when injected into the mold groove 3 through the injection port 6, preventing the generation of air bubbles and making the molded medical needle box of better quality and more aesthetically pleasing.

[0031] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
