Description

Technical Field

[0001] This utility model belongs to the field of mold technology and relates to an injection molding mold for a vacuum urine collection cup with a catheter. Background Technology

[0002] In the field of medical testing, urine vacuum collection cups are commonly used sample collection tools. To facilitate urine collection and transfer, a catheter structure is usually incorporated into the collection cup. Currently, most existing catheter-integrated urine vacuum collection cups are manufactured using a step-by-step molding process. This involves separately injection molding the collection cup and catheter, and then assembling them together in a subsequent two-in-one process. This step-by-step molding and assembly method has several problems: firstly, it requires multiple processes, resulting in a complex production flow, low production efficiency, and increased production costs; secondly, during assembly, the connection between the catheter and the collection cup is prone to problems such as poor sealing and weak connection, affecting product quality and potentially leading to sample leakage or contamination, thus impacting the accuracy of medical testing. Therefore, there is an urgent need for an injection molding mold for catheter-integrated urine vacuum collection cups that can overcome these shortcomings.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a urine cup injection mold with good injection molding effect [application number: 201922323403.0], which includes an upper fixed plate, a connecting plate, an injection port, a guide post, a lower fixed plate, a lower pad plate, and a mold core. The connecting plate is fixed above the upper fixed plate, the lower pad plate is located below the lower fixed plate, the guide post is located between the upper and lower fixed plates, and the guide post passes through the upper fixed plate, the connecting plate, and the lower fixed plate. The mold core is located between the upper and lower fixed plates, and the mold core includes an upper mold and a lower mold. The upper mold is fixed to the upper fixed plate, and the lower mold is fixed inside the lower fixed plate. However, this solution still cannot simultaneously inject the tubing structure that matches the urine cup during the injection molding process, and still requires secondary processing, resulting in high production costs and low efficiency. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing an injection molding mold for a vacuum urine collection cup with a catheter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vacuum urine collection cup injection molding die with catheter includes a lower injection mold and an upper injection mold. A plurality of auxiliary forming cylinders for the collection cup are disposed between the lower and upper injection molds. A catheter-synchronized forming structure extending into the auxiliary forming cylinders is provided below the lower injection mold.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown, a vacuum urine collection cup injection molding mold with a catheter includes a lower injection mold 1 and an upper injection mold 2. A plurality of auxiliary forming cylinders 3 for the collection cup are provided between the lower injection mold 1 and the upper injection mold 2. A catheter synchronous forming structure 4 extending into the auxiliary forming cylinders 3 is provided below the lower injection mold 1. An alignment fixing member 5 for fixing the auxiliary forming cylinders 3 is also provided between the lower injection mold 1 and the upper injection mold 2. An injection diverter 6 is provided above the upper injection mold 2.

[0027] In this embodiment, during the injection molding process, several collection cup auxiliary molding cylinders 3 are set between the lower mold 1 and the upper mold 2. Their main function is to construct the molding space for the urine vacuum collection cup. The conduit synchronous molding structure 4 set below the collection cup injection mold 1 can extend into the collection cup auxiliary molding cylinder 3 to achieve synchronous molding of the conduit with the collection cup. The alignment and fixing component 5 is used to ensure that the collection cup auxiliary molding cylinder 3 maintains a stable position during the injection molding process and prevents displacement. The injection flow divider 6 above the collection cup injection mold 2 can evenly distribute the injected plastic raw material to each molding part of the mold, forming a complete one-piece molding mold structure. Compared with the traditional step-by-step molding and assembly method, synchronous injection molding of the collection cup and conduit is achieved, which greatly improves production efficiency and product quality.

[0028] Combination Figure 1-4 As shown, the catheter synchronous molding structure 4 includes several catheter molding outer cylinders 7 disposed below the lower mold of the collection cup injection mold 1 and a molding inner insert rod 8. The top of the catheter molding outer cylinder 7 extends into the collection cup auxiliary molding cylinder 3.

[0029] Specifically, during the injection molding process, the inner insert rod 8 moves upward into the cavity and works in conjunction with the outer tube 7 to simultaneously form the tube structure, achieving one-piece molding and reducing subsequent assembly processes.

[0030] The catheter forming chamber 9 is formed between the outer tube 7 and the inner insert 8.

[0031] In this embodiment, the catheter forming chamber 9 is used to form the main structure of the collection cup.

[0032] Combination Figure 2 , Figure 4 As shown, the bottom of the molded inner insert rod 8 is provided with a leak-proof plug 10. The cross-section of the leak-proof plug 10 is larger than the cross-section of the molded inner insert rod 8. The leak-proof plug 10 matches the shape of the bottom of the catheter molding chamber 9.

[0033] In this embodiment, during the injection molding process, the leak-proof plug 10 can effectively prevent plastic raw materials from leaking from the bottom of the conduit molding chamber 9, ensuring the integrity and quality of the conduit molding. At the same time, after molding is completed, the leak-proof plug 10 moves down to help separate the molded conduit from the mold, avoiding problems such as adhesion caused by raw material leakage, thus improving the stability of production and the product qualification rate.

[0034] The lower mold of the collection cup injection mold 1 is provided with a fixed base plate 11 and a rod alignment plate 12. The rod alignment plate 12 is provided with a plurality of through grooves 13. The fixed base plate 11 is provided with a plurality of sliding grooves 14. The molded inner rod 8 passes through the sliding grooves 14 and extends into the through grooves 13.

[0035] In this embodiment, before injection molding, the size and position of the catheter molding chamber 9 can be precisely controlled by adjusting the position of the molding inner insert rod 8 in the slide groove 14 and through groove 13, ensuring the accurate relative position of the catheter and the collection cup, thereby achieving precise one-piece molding. During the injection molding process, the molding inner insert rod 8 remains stable to ensure the accuracy of catheter molding.

[0036] Combination Figure 4 As shown, the auxiliary molding cylinder 3 for the collection cup includes an upper outer cylinder 15, a lower outer cylinder 16, and an inner cylinder 17 for the collection cup, which are disposed between the lower mold 1 and the upper mold 2 of the collection cup. The upper outer cylinder 15, the lower outer cylinder 16, and the inner cylinder 17 form a main cavity.

[0037] In this embodiment, during the injection molding process, the plastic raw material is injected into the main cavity and cooled to form the collection cup. The top of the outer tube 7 of the conduit forming extends into the bottom of the main cavity, so that while the collection cup is being formed, the conduit forming chamber 9 can also receive the plastic raw material, realizing the synchronous forming of the conduit and the collection cup. The inner insert rod 8 can move along the side close to or away from the main cavity. This movement can adjust the shape and size of the conduit forming chamber 9 to meet the forming requirements of conduits of different specifications, further enhancing the versatility and practicality of the mold.

[0038] The top of the outer tube 7 of the conduit molding extends into the bottom of the main cavity, and the inner insert rod 8 of the molding can move along the side close to or away from the main cavity.

[0039] In this embodiment, the mobility of the inner insert rod 8 allows for flexible adjustment of the shape and size of the conduit during the injection molding process according to actual needs, ensuring a tight and suitable connection between the conduit and the collection cup, thereby improving product quality.

[0040] Combination Figure 1-4As shown, the alignment and fixing component 5 includes an upper outer cylinder clamping plate 18 and a lower outer cylinder positioning plate 19 disposed between the lower mold 1 and the upper mold 2 of the collection cup injection. The upper outer cylinder clamping plate 18 is fixed to the upper outer cylinder 15 of the collection cup forming, and the lower outer cylinder positioning plate 19 is engaged with the lower outer cylinder 16 of the collection cup forming.

[0041] In this embodiment, during the injection molding process, the upper outer cylinder clamping plate 18 is fixed to the upper outer cylinder 15 of the collection cup forming, and the lower outer cylinder positioning plate 19 is engaged with the lower outer cylinder 16 of the collection cup forming, thereby firmly fixing the collection cup auxiliary forming cylinder 3 between the collection cup injection mold 1 and the collection cup injection mold 2. This fixing method can ensure that the collection cup auxiliary forming cylinder 3 will not be displaced during the injection molding process, ensuring the forming accuracy of the collection cup and the conduit. At the same time, it facilitates the installation and disassembly of the collection cup auxiliary forming cylinder 3, facilitates the maintenance and replacement of the mold, and improves the convenience of production and the service life of the mold.

[0042] Combination Figure 1 As shown, the injection molding manifold 6 includes an injection molding manifold 20 disposed above the upper mold 2 of the collection cup injection molding.

[0043] In this embodiment, the injection manifold 20 is used to inject molten material into multiple cavities.

[0044] The working principle of this utility model is as follows:

[0045] During injection molding, the auxiliary molding cylinder 3 for the collection cup is fixed between the lower injection mold 1 and the upper injection mold 2 of the collection cup using the alignment and fixing parts 5 to ensure its accurate positioning. Then, the position of the inner insert rod 8 in the groove 14 of the fixed base plate 11 and the through groove 13 of the insert rod alignment plate 12 is adjusted to determine the size and position of the catheter forming chamber 9. After the mold is closed, the plastic raw material is injected into the injection diversion plate 20 above the upper mold 2 of the collection cup through the injection molding equipment. The injection diversion plate 20 evenly distributes the plastic raw material. Part of the raw material flows into the main cavity of the auxiliary forming cylinder 3 of the collection cup for forming the urine vacuum collection cup. The other part of the raw material enters the catheter forming chamber 9 through the top of the outer tube forming cylinder 7. In the chamber between the outer tube forming cylinder 7 and the inner insert rod 8, the catheter is formed. The leak-proof plug 10 at the bottom of the inner insert rod 8 prevents the plastic raw material from leaking from the bottom of the catheter forming chamber 9, ensuring the forming quality of the catheter. After the injection molding is completed, the plastic raw material is cooled and solidified. The mold is opened and the formed urine vacuum collection cup with catheter is taken out of the mold through the demolding mechanism, completing one injection molding process. The synchronous integral forming of the urine vacuum collection cup and the catheter is realized, which improves production efficiency and product quality.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model.
