Description

Technical Field

[0001] This utility model relates to the field of mold insert technology, specifically a mold insert for a variable diameter spiral cooling water channel. Background Technology

[0002] In the field of mold forming, the cooling effect of mold inserts plays a crucial role in product molding quality and production efficiency. Traditional mold inserts mostly use linear cooling water channels. While this type of channel is simple in structure, it suffers from poor cooling uniformity and is prone to cooling blind spots in complex parts of the mold, leading to defects such as product deformation and shrinkage marks, making it difficult to meet the molding requirements of high-precision products. Although spiral cooling water channels have emerged in existing technologies, extending the residence time of coolant within the insert through the spiral path and improving the cooling effect to some extent, the fixed diameter of each segment of the existing spiral cooling water channel makes it impossible to precisely cool different parts of the mold according to their heat dissipation needs, resulting in low cooling efficiency and energy waste. Furthermore, the connection structure of traditional spiral cooling water channels easily causes high coolant flow resistance and high energy loss, further affecting cooling performance. Therefore, there is an urgent need for a mold insert cooling water channel structure that can achieve precise cooling, improve cooling efficiency, and enhance product quality. Utility Model Content

[0022] 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.

[0023] like Figure 1-5 As shown, this utility model provides a mold insert for a variable diameter spiral cooling water channel 2, including an insert body 1. The insert body 1 has a spiral cooling water channel 2 inside. The spiral cooling water channel 2 includes a plurality of spiral water channel units 8 distributed along the axial direction of the insert body 1. The diameters of adjacent spiral water channel units 8 are different, and the diameters of the spiral water channel units 8 gradually increase or decrease along the flow direction of the coolant. Each spiral water channel unit 8 includes a spiral cooling channel and a connecting part 3 provided at both ends of the cooling channel. Adjacent spiral water channel units 8 are connected through the connecting part 3.

[0024] During the operation of the mold insert, the coolant from the external cooling system enters from the inlet 6 of the spiral cooling water channel 2 at one end of the insert body 1. Since the spiral cooling water channel 2 is composed of multiple spiral water channel units 8 with different diameters distributed along the axial direction of the insert body 1, and the diameter gradually changes along the flow direction of the coolant, when the coolant flows, according to the principle of fluid mechanics, the coolant flow rate is faster in the spiral water channel unit 8 with a smaller diameter, which can enhance the local cooling effect on the insert body 1; while in the spiral water channel unit 8 with a larger diameter, the coolant flow rate is slower, which helps the coolant to fully absorb heat and avoid over- or under-cooling.

[0025] Adjacent spiral water channel units 8 are connected by connecting parts 3 at both ends. The connecting parts 3 are inclined transition sections 9. This design allows the coolant to smoothly transition from a smaller diameter cooling channel to a larger diameter cooling channel, ensuring smooth coolant flow and reducing fluid resistance and energy loss.

[0026] The insert body 1 includes a main body 4 and a molding part 5, through which a spiral cooling water channel 2 runs. The outer wall of the molding part 5 is provided with a molding structure for molding the product. During the molding process, the spiral cooling water channel 2 is located close to the molding structure, which can promptly remove the large amount of heat generated by the molding part 5 during product molding, keeping the molding part 5 within a suitable temperature range and ensuring the product molding quality. Finally, the coolant, after absorbing heat, flows out from the outlet 7 at the other end of the insert body 1 and returns to the external cooling system for cooling circulation, achieving continuous cooling.

[0027] Furthermore, the connecting portion 3 is an inclined transition section 9. One end of the transition section 9 connects to the cooling channel with a smaller diameter, and the other end connects to the cooling channel with a larger diameter. The inclined transition section 9 reduces local turbulence losses caused by abrupt changes in cross-section, balances flow velocity and pressure loss, extends the life of the cooling pump, and saves energy costs.

[0028] Furthermore, the insert body 1 includes a main body 4 and a molded part 5 disposed at one end of the main body 4, and the spiral cooling water channel 2 penetrates the main body 4 and the molded part 5. The spiral path can conform to areas that traditional straight water channels cannot cover, such as curved surfaces and irregular ribs, eliminating local hot spots. The spiral diameter is reduced for areas prone to overheating, such as ribs and thin walls, to achieve precise temperature control.

[0029] Furthermore, the outer wall of the molding part 5 is provided with a molding structure for molding the product, and the spiral cooling water channel 2 is located close to the molding structure. The insert body 1 adopts the structural design of the main body 4 and the molding part 5, and the spiral cooling water channel 2 runs through both. This layout reasonably distributes the stress inside the insert.

[0030] Furthermore, the inlet 6 and outlet 7 of the spiral cooling water channel 2 are respectively located at both ends of the insert body 1, and both the inlet 6 and outlet 7 are connected to an external cooling system. The design of the variable-diameter spiral cooling water channel 2 allows for changes in the flow rate of the coolant at different locations within the insert body 1, enabling precise cooling for different parts based on their heat dissipation needs. For areas with concentrated heat, the smaller diameter spiral water channel unit 8 can accelerate the coolant flow rate and quickly remove heat.

[0031] Furthermore, the insert body 1 is made of metal, and the inner wall of the spiral cooling water channel 2 is provided with an anti-rust coating 10. The anti-rust coating 10 on the inner wall of the spiral cooling water channel 2 can extend the service life of the insert, reduce malfunctions such as water leakage caused by corrosion of the cooling water channel, and ensure the structural stability and reliability of the mold during long-term use.

[0032] Furthermore, the cross-sectional shape of the spiral cooling water channel 2 can be circular, elliptical, or polygonal. The cross-sectional shape of the spiral cooling water channel 2 can be selected as circular, elliptical, or polygonal, allowing for flexible design based on different mold application scenarios and product molding requirements, thus meeting diverse production needs. In addition, the connection method between the inlet 6 and outlet 7 and the external cooling system facilitates connection with different types of cooling equipment, enhancing the applicability and versatility of this mold insert in actual production.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
