[0002] In the field of medical devices, fluid collection boxes are crucial auxiliary equipment, playing an indispensable role in various medical scenarios, such as the collection of waste fluids during surgery and the temporary storage of test samples. Their design and performance directly affect the safety and effectiveness of medical procedures, as well as the patient's medical experience.

[0003] In the production of liquid collection boxes, the sealing performance of the mold is crucial. Traditional liquid collection box molds have many shortcomings in sealing, and the common single-seal structure is prone to leakage of plastic melt during injection molding. Once leakage occurs, it will not only affect the molding quality of the liquid collection box, causing defects such as flash and short material, but may also damage the mold, increasing maintenance costs and production cycle. Moreover, traditional molds are difficult to adapt to the sealing requirements of side plates of different thicknesses, lack flexibility for diverse product designs, and cannot meet the growing market demand. Utility Model Content

[0004] This invention aims to at least partially solve one of the problems in the related art. Therefore, one objective of this invention is to provide a liquid collection box mold for improving the sealing performance of the liquid collection box mold.

[0005] A liquid collection box mold, the liquid collection box mold comprising:

[0006] A base mold base, comprising an upper mold base and a lower mold base;

[0007] A core module, wherein the core module is disposed between the upper mold base and the lower mold base;

[0008] A movable side plate, which is movably disposed on one side of the base mold base and abuts against the core module;

[0009] A sealing assembly, comprising a first sealing element and a second sealing element, wherein a first sealing groove is provided at the connection between the upper mold base and the lower mold base and the core module, and the first sealing element is disposed in the first sealing groove; a second sealing groove is provided at the corresponding position of the upper mold base and the lower mold base and the movable side plate, and the second sealing element is disposed in the second sealing groove; the second sealing element is a position-adjustable sealing strip.

[0010] Furthermore, the first sealing element is a rubber sealing ring.

[0011] Furthermore, the cross-sectional shape of the first seal is one of a circle, a square, or a trapezoid.

[0012] Furthermore, the first sealing element has a multi-layer composite structure.

[0013] Furthermore, the first sealing groove has several protrusions on its groove wall, and the first sealing element has several grooves on its outer peripheral surface, with the protrusions and grooves engaging with each other.

[0014] Furthermore, the second sealing element includes a main rubber strip and an adjusting block. One side of the main rubber strip is provided with an adjusting groove that mates with the adjusting block. The adjusting block is installed in the adjusting groove by means of threaded connection or snap-fit.

[0015] Furthermore, the second sealing groove is a T-shaped groove, and the bottom shape of the second seal is adapted to the T-shaped groove.

[0016] Furthermore, both the bottom of the first sealing groove and the second sealing groove are provided with an elastic buffer layer, which is made of rubber or silicone material.

[0017] Furthermore, both the first and second seals are coated with a sealing coating, which is a polytetrafluoroethylene coating or a silicone coating.

[0018] Furthermore, the base mold is provided with positioning pins and positioning holes, and the core module and the movable side plate are respectively provided with structures that cooperate with the positioning pins and positioning holes.

[0019] The technical solutions provided in this application have the following advantages compared with the prior art:

[0020] This application employs a dual-sealing design concept. A first sealing groove is provided at the junction of the core module and the base mold base. A first sealing element is installed within this groove, which, under injection pressure, tightly seals the contact surfaces of the core module and the base mold base, effectively preventing leakage of the molten plastic, ensuring the molding quality of the molten plastic box, and reducing product defects. A second sealing groove is provided between the movable side plate of the mold and the base mold base. A second sealing element, which is an adjustable sealing strip, is installed on the base mold base at the position corresponding to the movable side plate. This further enhances the overall sealing effect, preventing molten plastic from leaking from the gap between the movable side plate and the base mold base.

[0021] The double-sealing structure effectively prevents leakage of molten plastic during injection molding, reducing defects in the liquid collection box products, such as flash and insufficient material, improving the molding quality of the product, and enabling the produced liquid collection boxes to meet higher quality standards.

[0033] like Figure 1 - Figure 3 As shown, the liquid collection box mold 1 provided in this application includes:

[0034] The basic mold base 10 includes an upper mold base 11 and a lower mold base 13;

[0035] Core module 30, which is located between upper mold base 11 and lower mold base 13;

[0036] Movable side plate 50 is movably disposed on one side of the base mold 10 and abuts against the core module 30;

[0037] The sealing assembly 70 includes a first sealing element 71 and a second sealing element 73. A first sealing groove 15 is provided at the connection between the upper mold base 11 and the lower mold base 13 and the core module 30. The first sealing element 71 is disposed in the first sealing groove 15. A second sealing groove 17 is provided at the corresponding position of the upper mold base 11 and the lower mold base 13 and the movable side plate 50. The second sealing element 73 is disposed in the second sealing groove 17. The second sealing element 73 is a position-adjustable sealing strip.

[0038] The base mold 10, composed of an upper mold base 11 and a lower mold base 13, serves as the main support for the mold. The upper and lower mold bases 13 provide the mounting foundation for the core module 30, the movable side plate 50, and the sealing assembly 70; their structural strength and stability directly affect the overall performance of the mold. A well-designed upper and lower mold base 13 ensures no deformation under injection pressure, guarantees precise relative positions of all components, and thus ensures the molding accuracy of the molten plastic box. During production, a stable base mold 10 reduces the risk of molten plastic leakage due to vibration and displacement, improving product quality and production efficiency.

[0039] The core module 30, located between the upper mold base 11 and the lower mold base 13, determines the internal shape and dimensions of the liquid accumulation box. Its design precision and surface quality are crucial to the molding quality of the liquid accumulation box. A high-precision core module 30 ensures that the internal structure of the liquid accumulation box meets design requirements, avoiding problems such as uneven wall thickness and dimensional deviations. Simultaneously, the tight fit between the core module 30 and the upper and lower mold bases 13, as well as its abutting relationship with the movable side plate 50, ensures the integrity of the mold cavity, providing precise space for the filling of the plastic melt, and is a key component for achieving correct molding of the liquid accumulation box.

[0040] The movable side plate 50 is movably positioned on one side of the base mold 10 and abuts against the core module 30. This design allows the mold to flexibly adjust the cavity size to adapt to the production needs of liquid collection boxes with different capacities. By moving the movable side plate 50, the internal space of the mold can be changed, enabling the production of multiple specifications of liquid collection boxes from a single mold, improving the mold's versatility and reducing mold development costs. Furthermore, the tight abutment between the movable side plate 50 and the core module 30, combined with the sealing component 70, effectively prevents molten plastic from leaking from the side, ensuring sealing performance and product quality.

[0041] A first sealing groove 15 is provided at the connection between the upper mold base 11 and the lower mold base 13 and the core module 30, and a first sealing element 71 is installed thereon. The function of the first sealing element 71 is to prevent the plastic melt from leaking at the joint between the core module 30 and the base mold base 10. Its tight fit with the first sealing groove 15 is crucial. A good sealing effect can prevent the plastic melt from overflowing, ensure the molding quality of the molten plastic box, and reduce defects such as flash and material shortage. The first sealing element 71 of different materials and structures, such as rubber sealing rings, can fit tightly against the contact surface under injection pressure due to its elasticity, thereby enhancing the sealing performance.

[0042] Second sealing grooves 17 are formed at corresponding positions on the upper mold base 11 and lower mold base 13, corresponding to the movable side plate 50, and second sealing elements 73 (adjustable sealing strips) are installed thereon. The second sealing element 73 primarily prevents molten plastic from leaking through the gap between the movable side plate 50 and the base mold base 10. The adjustable sealing strip can be adjusted according to the thickness of the movable side plate 50 and actual sealing requirements, ensuring good sealing under different working conditions. This adjustability improves the mold's adaptability to different side plate thicknesses, expands the mold's application range, and enhances overall sealing performance, reducing the risk of leakage.

[0043] Furthermore, the first sealing element 71 is a rubber sealing ring.

[0044] The first sealing element 71 is specifically a rubber sealing ring. Rubber possesses good elasticity and flexibility, allowing it to deform under pressure and fill the gap between the sealing groove and the core module 30, thus achieving a good sealing effect. Simultaneously, rubber exhibits good chemical stability, resisting certain levels of high temperatures and chemical corrosion, making it suitable for the complex environment of the injection molding process. Furthermore, rubber sealing rings are low-cost and readily available, reducing mold production costs. Their good elasticity ensures effective sealing under different injection pressures, reducing the risk of plastic melt leakage and improving product quality and production efficiency.

[0045] Furthermore, the cross-sectional shape of the first seal 71 is one of a circle, a square, or a trapezoid.

[0046] Circular cross-section rubber sealing rings offer uniform elasticity, providing good sealing performance in all directions and are easy to install. Square cross-section rubber sealing rings provide a larger sealing area, enhancing sealing reliability. Trapezoidal cross-section rubber sealing rings can provide stronger sealing force in specific directions according to specific sealing requirements. A variety of cross-sectional shapes are available, allowing for optimized mold design based on different application scenarios and sealing requirements. Different shaped rubber sealing rings better adapt to the structural characteristics of the mold, improving sealing performance and further ensuring the molding quality of the liquid collection box.

[0047] Furthermore, the first seal 71 has a multi-layer composite structure.

[0048] Multi-layer composite structures combine materials with different properties. For example, the inner layer uses a material with good elasticity to ensure a good seal, while the outer layer uses a wear-resistant and corrosion-resistant material to improve the service life of the seal. This design can fully utilize the advantages of various materials and overcome the limitations of a single material. Understandably, the first seal 71 of the multi-layer composite structure has better overall performance, ensuring a good seal while improving the wear and corrosion resistance of the seal, extending the service life of the seal, and reducing the maintenance cost and replacement frequency of the mold.

[0049] Furthermore, the first sealing groove 15 has several protrusions on its groove wall, and the first sealing member 71 has several grooves on its outer peripheral surface, with the protrusions and grooves engaging and locking together.

[0050] The interlocking engagement of the protrusion and the groove increases the friction and contact area between the first seal 71 and the first sealing groove 15, preventing the seal from shifting or falling off during injection molding. Simultaneously, this structure further enhances the sealing effect, preventing molten plastic from leaking through the gap between the seal and the sealing groove.

[0051] Furthermore, the second sealing element 73 includes a main rubber strip 731 and an adjusting block 733. One side of the main rubber strip 731 is provided with an adjusting groove that mates with the adjusting block 733. The adjusting block 733 is installed in the adjusting groove by means of threaded connection or snap-fit.

[0052] The adjustable second seal 73 can be flexibly adjusted according to different sealing requirements and side plate thicknesses. The adjusting block 733, installed via threaded connection or snap-fit, allows for easy modification of the sealing state of the main sealing strip 731 to adapt to various working conditions. The adjustable second seal 73 enhances the mold's adaptability, meeting the sealing requirements of side plates of varying thicknesses. Operators can adjust it according to actual conditions to ensure optimal sealing, thus improving the mold's versatility and practicality.

[0053] Furthermore, such as Figure 3 As shown, the second sealing groove 17 is a T-shaped groove, and the bottom shape of the second sealing member 73 is adapted to the T-shaped groove.

[0054] The T-groove, combined with the bottom shape of the matching second seal 73, increases the installation stability and sealing effect of the seal. The T-groove structure provides a larger contact area and better restraint, preventing the seal from shifting or loosening during use. The T-groove structure improves the installation reliability of the second seal 73, ensuring that the seal is accurately installed within the sealing groove and remains stable. This structural design enhances the sealing effect, reduces the possibility of molten plastic leaking from the gap between the movable side plate 50 and the base mold 10, and improves product quality.

[0055] Furthermore, such as Figure 3 As shown, the bottom of both the first sealing groove 15 and the second sealing groove 17 is provided with an elastic buffer layer 19, which is made of rubber or silicone material.

[0056] The elastic buffer layer 19 provides cushioning when the seal is compressed, reducing pressure and wear on the seal. The rubber or silicone material has good elasticity and flexibility, effectively absorbing and dispersing pressure while enhancing the sealing effect. The elastic buffer layer 19 extends the service life of the seal and reduces seal damage caused by excessive pressure. It also improves sealing performance by allowing the seal to better conform to the sealing groove through cushioning, reducing the risk of molten plastic leakage and improving product quality and mold reliability.

[0057] Furthermore, the surfaces of the first seal 71 and the second seal 73 are both coated with a sealing coating, which is a polytetrafluoroethylene coating or a silicone coating.

[0058] PTFE and silicone coatings offer excellent lubricity, corrosion resistance, and sealing performance. Applying these coatings reduces friction between the seal and other components, prevents chemical corrosion of the seal, and enhances sealing effectiveness. Sealing coatings improve the sealing performance of the seal, reducing the likelihood of molten plastic leakage. They also enhance the durability of the seal, extend its service life, reduce mold maintenance costs and replacement frequency, and improve production efficiency.

[0059] Furthermore, the base mold 10 is provided with positioning pins and positioning holes, and the core module 30 and the movable side plate 50 are respectively provided with structures that cooperate with the positioning pins and positioning holes.

[0060] The engagement of the locating pins and locating holes provides precise positioning, ensuring that the core module 30 and the movable side plate 50 are accurately aligned with the base mold 10 during installation. This positioning structure improves the assembly accuracy of the mold and reduces product quality issues caused by inaccurate component installation. The positioning structure enhances the assembly accuracy and stability of the mold, ensuring accurate molding dimensions of the liquid collection box. It reduces product defects caused by component misalignment, increasing the product yield. Simultaneously, the positioning structure facilitates mold installation and disassembly, improving production efficiency.
