下面将参考附图并结合实施例，详细说明本申请。The present application will be described in detail below with reference to the accompanying drawings and embodiments.
如图1至图3所示，一种大型射砂嘴，包括射嘴本体1、以及作为易损更换件的射嘴头2。所述射嘴头2的一端套接在射嘴本体1的开口端内，射嘴头2的另一端设有挡砂直段21。所述挡砂直段21内设有射嘴挡片筋22。所述射嘴挡片筋22呈网状结构布满挡砂直段21内部，网状结构可采用蛛网结构，也可采用十字形网结构。射嘴挡片筋22之间形成的若干网眼作为射嘴孔23。其中，相比于常规射嘴内径(射嘴孔23内部通过芯砂的直径)最大的Φ21mm，本实施例中的射嘴内径可扩大到Φ21mm-Φ150mm的之间。若在未设置射嘴挡片筋22的情况下直接扩大射嘴内径，则会导致砂子通过大孔直接、不断泄漏。采用射嘴挡片筋22后，则会分隔大孔，以阻隔砂子，防止砂子的泄漏而降低砂芯质量。As shown in Figures 1 to 3, a large sand shooting nozzle includes a nozzle body 1 and a nozzle head 2 as a vulnerable replacement part. One end of the nozzle head 2 is sleeved in the open end of the nozzle body 1 , and the other end of the nozzle head 2 is provided with a sand-blocking straight section 21 . The sand blocking straight section 21 is provided with a nozzle blocking rib 22 . The nozzle blocking ribs 22 are in the form of a mesh structure covering the inside of the sand blocking straight section 21. The mesh structure can be a spider web structure or a cross-shaped web structure. Several meshes formed between the nozzle baffle ribs 22 serve as the nozzle holes 23 . Among them, compared with the maximum inner diameter of the conventional nozzle (the diameter of the core sand passing through the nozzle hole 23) of Φ21mm, the inner diameter of the nozzle in this embodiment can be expanded to between Φ21mm and Φ150mm. If the inner diameter of the nozzle is directly expanded without setting the nozzle baffle rib 22, sand will leak directly and continuously through the large hole. After the nozzle baffle rib 22 is adopted, the large holes will be separated to block the sand and prevent the leakage of the sand from reducing the quality of the sand core.
所述射嘴头2、挡砂直段21和射嘴挡片筋22为一体结构。The nozzle head 2, the sand blocking straight section 21 and the nozzle blocking rib 22 are an integrated structure.
所述射嘴头2外露的侧面上套设有射嘴套3，用于射嘴时的密封，其中，射嘴套3可采用橡胶材质。The exposed side of the nozzle head 2 is provided with a nozzle cover 3 for sealing the nozzle. The nozzle cover 3 can be made of rubber.
如图2所示，所述射嘴套3的根部对应的射嘴头2侧面处开有沟槽结构。射嘴套3的根部设有相应的凸起结构与射嘴头2上的沟槽结构配合钩接，用于防止射嘴套3掉落。As shown in Figure 2, a groove structure is formed on the side of the nozzle head 2 corresponding to the root of the nozzle cover 3. The root of the nozzle cover 3 is provided with a corresponding protruding structure to cooperate with the groove structure on the nozzle head 2 to prevent the nozzle cover 3 from falling.
所述射嘴头2的外侧与射嘴本体1的开口内侧之间通过螺纹结构旋接在一起，便于旋松更换射嘴头2。The outside of the nozzle head 2 and the inside of the opening of the nozzle body 1 are screwed together through a threaded structure, making it easy to loosen and replace the nozzle head 2 .
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
