The utility model discloses a die-casting production die-shooting hammer head, which makes the whole surface of the hammer exchange heat equally by setting a spiral water path in the main body of the hammer head. The hammer head has simple structure, is convenient and practical, and can effectively improve the cooling effect of the hammer head. The hammer head is characterized in that a plurality of wear-resistant strips are equidistantly placed outside the main body of the hammer head, and the main body of the hammer head is hollow. The installation chuck is arranged on one side of the main body of the hammer head. The middle part of the installation chuck is provided with through holes, which are connected with the inner part of the main body of the hammer head. One end of the middle diversion pipe is placed in the main body of the hammer head, and is connected with the inner wall of the other end of the main body of the hammer head. The other end of the middle diversion pipe penetrates through the installation chuck, and an annular cavity is arranged between the outer wall of the middle diversion pipe and the inner wall of the main body of the hammer head. The helical plate and the inner wall of the main body of the hammer are arranged on the outer wall of the middle diversion tube and in an annular cavity between the inner wall of the main body of the hammer head and the outer wall of the middle diversion tube.
【技术实现步骤摘要】
一种压铸生产压射锤头
本技术一种压铸生产压射锤头,涉及一种在模具进行压铸生产时,通过水的循环流动对自身进行冷却降温的压射锤头,属于机械加工领域。特别涉及一种通过在锤头主体内设置螺旋形水路,使得锤头整个表面均衡的进行热量交换的压射锤头。
技术介绍
目前,在压铸过程中,压铸生产需要将金属液注入压室内,然后通过压射杆推动锤头,对压室内的金属液进行推送,使得金属液向模具型腔内填充,因此锤头在压室内的配合公差要求严格,且材质的选择要求高,需要考虑热膨胀下的配合间隙,由于金属液的温度较高,对锤头的影响较大,当锤头受热膨胀时,和压室内壁形成紧配合,然后在推动金属液时,会存在卡滞,使得金属液的填充速度瞬间下降,增加金属液内含气量,严重的会直接卡滞在压室内,影响生产,当锤头温度下降,和压室之间的间隙变大,金属液会沿着间隙回流,出现跑水的情况,影响成型质量,因此需要对锤头的温度进行控制,同时还配合锤头润滑结构,但单一的依靠润滑或温控的方法效果有限,现有的一些锤头的冷却方式都是单一的导出管直接进入锤头内,通过和锤头的热交换后,将热量带出,但和锤头的接触时间较短,无法充分的和水头进行热交 ...
