为了防止成型块5对产品进行顶出时对产品表面造成刮伤,出现凹陷或凸起,成型块5的顶端面具有与定模2上表面相同的弧形。In order to prevent the product surface from being scratched and dented or raised when the forming block 5 pushes out the product, the top surface of the forming block 5 has the same arc shape as the upper surface of the fixed die 2 .
在本实施例中,下连接部15的宽度大于上接触部13的宽度,下连接部15的底端面抵接于顶推块9的顶端面上,再配合以滑块11与滑道10之间的连接,使得下连接部15与顶推块9配合更加紧密,避免出现活动间隙。In this embodiment, the width of the lower connecting portion 15 is greater than the width of the upper contact portion 13 , the bottom surface of the lower connecting portion 15 abuts on the top surface of the push block 9 , and the sliding block 11 and the slideway 10 are matched with each other. The connection between the lower connection parts 15 and the push block 9 is more closely matched, so as to avoid the occurrence of movement gaps.
顶推块9上设置有用于连接顶推块9与顶推杆8连接的固定件17,固定件17可为螺栓,滑道10上开设有向下凹陷用于固定件17安装的安装孔18,安装孔18的深度大于固定件17的高度,固定件17安装时,,整体容纳于安装孔18内,不影响滑块11的正常滑动。The ejector block 9 is provided with a fixing member 17 for connecting the ejector block 9 and the ejector rod 8. The fixing member 17 can be a bolt, and the slideway 10 is provided with a downwardly recessed mounting hole 18 for the installation of the fixing member 17. , the depth of the mounting hole 18 is greater than the height of the fixing piece 17 , when the fixing piece 17 is installed, the whole is accommodated in the mounting hole 18 and does not affect the normal sliding of the slider 11 .
本实用新型的工作原理为:定模2与动模1盖合之后,成型腔3主要用于产品整体形状的成型,定模2上的内槽4与成型块5相配合用于产品凹陷结构的成型,当产品成型完全之后需要对该部分进行脱模与抽芯处理,此时,可通过油缸或者气缸驱动移动板7朝向动模1一侧运动,利用成型块5自身对产品起到一个顶出的作用,在向上移动的过程中,由于穿孔16是倾斜设置的,当顶推杆8竖直向上运动时,成型块5的上成型部14会随着滑块11的移动而移动,向朝向远离成型间隙6一侧运动,从产品中脱离出来,达到抽芯的目的。The working principle of the utility model is as follows: after the fixed mold 2 is covered with the movable mold 1, the molding cavity 3 is mainly used for the molding of the overall shape of the product, and the inner groove 4 on the fixed mold 2 cooperates with the molding block 5 for the product concave structure. When the product is completely formed, the part needs to be demolded and core-pulled. At this time, the oil cylinder or the cylinder can drive the moving plate 7 to move toward the side of the movable mold 1, and use the forming block 5 itself to play a role in the product. During the upward movement, because the perforations 16 are arranged obliquely, when the ejector rod 8 moves vertically upward, the upper forming part 14 of the forming block 5 will move with the movement of the sliding block 11. Move to the side away from the forming gap 6 to be separated from the product to achieve the purpose of core pulling.
