Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a 3D metal printing preform injection mold with a spiral water channel. Background Technology

[0002] During the injection molding process of bottle preforms, residual thermal stress tends to occur in two stages: first, during the cooling stage of the preform in the mold cavity, and second, during the cooling stage from the demolding temperature to room temperature. Therefore, to achieve high-efficiency production and obtain high-performance injection molded products, mold temperature control is essential. Mold temperature directly affects the quality and production efficiency of injection molded products, and it is primarily controlled and regulated through the mold's cooling system. Traditional cooling channels can only be machined into simple straight holes; when the injection molded part has a complex shape, their cooling effect is poor, leading to significant part deformation. Utility Model Content

[0003] To address the aforementioned issues, this invention aims to provide a 3D metal printing preform injection mold with a spiral water channel, which has a novel and reliable structure and good cooling effect.

[0004] The technical solution of this utility model is a 3D metal printed bottle preform injection mold with a spiral water channel. Its features include: a mold core made of 3D metal printing; a bottle preform product cavity is provided inside the mold core; a spiral cooling water channel is provided inside the mold core; the spiral cooling water channel is arranged around the outside of the bottle preform product cavity; the inlet and outlet of the spiral cooling water channel are located on the left and right sides of the upper region of the mold core; and the cross-section of the spiral cooling water channel is teardrop-shaped.

[0005] Preferably, the preform product cavity is arranged along the height direction of the mold core. The upper part of the preform product cavity is hemispherical, the middle part is cylindrical, and the lower part is a frustum-shaped structure with a smaller upper part and a larger lower part. The top of the spiral cooling water channel is located outside the top of the upper part of the preform product cavity, and the bottom of the spiral cooling water channel is located outside the bottom of the lower part of the preform product cavity.

[0006] This invention uses 3D metal printing to create internal spiral cooling channels, resulting in a novel and reliable structure with excellent cooling performance. Attached Figure Description

[0013] The present invention will now be described in further detail with reference to the accompanying drawings.

[0014] like Figures 1 to 5 As shown, this utility model provides a 3D metal printed bottle preform injection mold with a spiral water channel, including a mold core 1 made of 3D metal printing, a bottle preform product cavity 2 is provided inside the mold core 1, a spiral cooling water channel 3 is provided inside the mold core 1, the spiral cooling water channel 3 is arranged around the outside of the bottle preform product cavity 2, the inlet 31 and outlet 32 ​​of the spiral cooling water channel 3 are located on the left and right sides of the upper region of the mold core 1, and the cross-section of the spiral cooling water channel 3 is teardrop-shaped.

[0015] In the above scheme, the preform product cavity 2 is set along the height direction of the mold core 1. The upper part of the preform product cavity 2 is hemispherical, the middle part is cylindrical, and the lower part is a frustum-shaped structure with a smaller upper part and a larger lower part. The top of the spiral cooling water channel 3 is located outside the upper top of the preform product cavity 2, and the bottom of the spiral cooling water channel 3 is located outside the lower bottom of the preform product cavity 2.

[0016] In this invention, since the mold core 1 is made by 3D metal printing, the spiral cooling channel 3 can be pre-formed during the 3D metal printing process, allowing for the smooth formation of the spiral cooling channel 3. The teardrop-shaped tip area can be set outwards, which allows the water channel to have a larger cross-sectional area during the spiral cooling process, enabling it to more effectively remove heat from the mold and thus improve cooling efficiency.

[0017] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
