Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a multi-layer water channel core mold mechanism. Background Technology

[0002] In the manufacturing and use of injection molds, the water channel design of the mold head plays a crucial role in the efficiency of the entire injection molding process and the mold's lifespan. Traditional one-piece core designs present significant challenges in processing, especially for products with complex shapes and high precision requirements, making it difficult to guarantee machining accuracy. Furthermore, because one-piece cores must withstand substantial friction and heat loads during injection molding, they are prone to frictional wear, which in turn affects the mold's lifespan.

[0003] In existing technologies, mold cores are typically made from a single material. While this solves the processing difficulty to some extent, their wear resistance remains poor, resulting in a short mold lifespan. Furthermore, when the mold core wears out, the entire core needs to be replaced, increasing maintenance and replacement costs. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer water channel core mold mechanism to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-layer water channel core mold mechanism, comprising:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See Figure 1 As shown, this utility model provides a multi-layer water channel core mold mechanism, including: an inner core 1, which has a first inlay space 11, in which an inner beryllium copper inlay 6 and an inner iron inlay 5 are arranged sequentially from the inside to the outside; an outer core 2 is arranged on the inner core 1; the outer core 2 and the inner core 1 form a second inlay space 21, in which an outer beryllium copper inlay 4 and an outer iron inlay 3 are arranged sequentially from the inside to the outside; a water channel structure is provided between the inner core 1 and the inner beryllium copper inlay 6 and the inner iron inlay 5, and between the outer core 2 and the outer beryllium copper inlay 4 and the outer iron inlay 3.

[0025] The aforementioned structural design is installed at the water channel structure position at the core head. During injection molding, the cooling medium flows through the water channel, the beryllium copper insert rapidly conducts heat, and the iron insert provides structural support and protection. When maintenance is required, only the iron insert needs to be removed, and the worn beryllium copper insert can be taken out and replaced. The operation is simple and quick, without needing to replace the entire core, thus reducing maintenance costs. Furthermore, due to the different material configuration, friction between components is reduced during product ejection, extending service life.

[0026] Specifically, the first inlay space 11 is composed of a first short mounting hole 112 and a first long mounting hole 111. The inner beryllium copper inlay 6 is installed in the first long mounting hole 111, and the inner iron inlay 5 is installed in the first short mounting hole 112.

[0027] The second mounting space 21 is composed of a second short mounting hole 212 and a second long mounting hole 211. The outer beryllium copper insert 4 is installed in the second long mounting hole 211, and the outer iron insert 3 is installed in the second short mounting hole 212.

[0028] The iron inserts provide excellent support, strength, and wear resistance, making the structure more stable, while the beryllium copper inserts have good thermal conductivity, effectively transferring heat and making them suitable for applications requiring rapid heat dissipation. Furthermore, the design of mounting holes of varying lengths offers more flexible configuration and installation options in actual production, improving its adaptability. The separate placement of the two inserts also facilitates replacement and maintenance, reducing overall maintenance costs and time. Sealing rings are installed between the inner core 1, outer core 2, inner beryllium copper insert 6, inner iron insert 5, outer beryllium copper insert 4, and outer iron insert 3, improving the overall sealing performance of the core.

[0029] Furthermore, the water system structure includes: a first pipe 12 disposed in the inner core 1, which communicates with the first inlay space 11; a second pipe 61 in a cross shape disposed within the inner beryllium copper inlay 6; and a third pipe 51 corresponding to the second pipe 61 disposed within the inner iron inlay 5. An arc-shaped pipe 52 communicating with the third pipe 51 is disposed on the inner iron inlay 5.

[0030] The liquid medium flows rapidly and efficiently between the various components. In particular, the cross-shaped layout of the second pipe 61 within the beryllium copper insert enhances fluid distribution and circulation, improving overall cooling efficiency. The cross-shaped second pipe 61 provides multiple fluid channels, reducing resistance during fluid flow and thus increasing flow rate and velocity, ensuring optimal heat exchange efficiency. The third pipe 51 corresponds to the second pipe 61, forming a good heat exchange interface for more efficient heat conduction. The integrated pipe design makes the water circuit structure more compact, saving space and reducing connection points between components, thus lowering the risk of potential leaks. The curved pipe 52 effectively guides fluid flow, avoiding flow disturbances caused by sharp turns; this design helps maintain fluid stability and continuity.

[0031] In addition, the water system structure also includes a fourth pipe 22 disposed in the outer core 2, which communicates with the second inlay space 21. The outer beryllium copper insert 4 has a notch 41 communicating with the fourth pipe 22. The opening of this notch 41 is shielded by an outer iron insert 3. The connection between the fourth pipe 22 and the second inlay space 21 optimizes fluid distribution, ensuring that the liquid is evenly distributed throughout the structure, thus improving cooling or heating efficiency. Through the rational layout of the fourth pipe 22 and the notch 41, the entire water system structure can be more compact, saving space and facilitating equipment installation and maintenance. The combination of the shielded notch 41 and the outer iron insert guides the flow direction of the fluid, reducing eddies and unnecessary pressure loss, resulting in smoother flow and improved overall flow efficiency. The shielding effect of the outer iron insert 3 protects the water system structure, reducing the risk of external physical damage and enhancing the overall durability and reliability of the system.

[0032] In this embodiment, the inner core 1 and the outer core 2 are mounted on the moving mold 8. The moving mold 8, the inner core 1, the outer core 2, the inner beryllium copper insert 6, the inner iron insert 5, the outer beryllium copper insert 4, the outer iron insert 3, and the fixed mold 9 are closed to form a molding cavity 7. A gating pipe 10 is provided inside the moving mold 8. By pouring the injection molding liquid into the gating pipe 10, the material is ensured to flow smoothly into the molding cavity 7, thereby achieving product molding. For demolding of the injection molded product, methods such as threaded demolding, mechanical demolding, pneumatic demolding, or hydraulic demolding are selected according to actual needs.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
