技术领域technical field
本发明涉及模具加工技术领域，具体涉及一种低压铸造冷铁散热片式模具结构。The invention relates to the technical field of mold processing, in particular to a cooling fin type mold structure for low pressure casting.
背景技术Background technique
在铸造生产中，为避免铸件产生缩孔、缩松或裂纹等质量缺陷，需要在铸件壁厚较厚的部位加放冷铁，从而提高工艺出品率、铸件局部的金相组织和力学性能。传统冷铁结构，冷却靠风环和水路进行强冷却，这种冷却方式容易破坏周边的温度场，造成产品周边出现不良。In casting production, in order to avoid quality defects such as shrinkage cavities, shrinkage porosity or cracks in castings, it is necessary to add chilled iron in the thicker parts of castings, so as to improve the process yield, metallographic structure and mechanical properties of castings. The traditional cold iron structure is cooled by the wind ring and waterway for strong cooling. This cooling method is easy to damage the surrounding temperature field, resulting in defects around the product.
发明内容Contents of the invention
本发明的目的在于提供一种低压铸造铁冷散热片式模具结构。The object of the present invention is to provide a low-pressure cast iron cooling fin type mold structure.
本发明的技术方案是：一种低压铸造冷铁散热片式模具结构，包括设置在铸造模具侧模上的冷铁，冷铁的一侧设有用于铸造成型的成型腔，冷铁具有若干个延伸至位于铸件较厚处的成型腔内壁表面的吸热接触点，冷铁远离成型腔的一侧设有散热结构。The technical solution of the present invention is: a low-pressure casting chill iron heat sink type mold structure, including chill iron arranged on the side mold of the casting mold, one side of the chill iron is provided with a molding cavity for casting molding, and the chill iron has several Extending to the heat-absorbing contact point on the inner wall surface of the molding cavity at the thicker part of the casting, the cooling iron is provided with a heat dissipation structure on the side away from the molding cavity.
进一步的技术方案，散热结构为铝散热单片，散热单片形成多个均匀分布的凸起，相邻凸起之间形成凹槽，凸起与凹槽相间分布，凹槽的底部紧贴在冷铁上。In a further technical solution, the heat dissipation structure is an aluminum heat dissipation sheet, and the heat dissipation sheet forms a plurality of evenly distributed protrusions, and grooves are formed between adjacent protrusions, and the protrusions and grooves are alternately distributed, and the bottom of the groove is closely attached to the On the cold iron.
进一步的技术方案，凸起与凹槽之间的过渡面呈倾斜面设置。In a further technical solution, the transition surface between the protrusion and the groove is provided as an inclined surface.
本发明的有益效果：Beneficial effects of the present invention:
本发明中通过在冷铁背面设置散热片造型，通过直接增加冷铁与空气接触的面积来达到冷却效果，避免冷却靠风环和水路进行强冷却引起的造型出现疏松的现象，本发明提供的冷铁结构能够不影响周边结构，满足低压铸造结构的高精度要求。In the present invention, cooling fins are arranged on the back of the chilled iron, and the cooling effect is achieved by directly increasing the contact area between the chilled iron and the air, so as to avoid loosening of the shape caused by strong cooling by the wind ring and water channels. The present invention provides The cold iron structure can not affect the surrounding structure, and meets the high-precision requirements of the low-pressure casting structure.
