一种球拍外形切割用刀模

Abstract

本实用新型涉及刀模技术领域，具体涉及为一种球拍外形切割用刀模，包括刀模主体，所述刀模主体包括拍柄刀模、拍面刀模，所述拍面刀模固定连接于所述拍柄刀模末端缺口处，所述拍面刀模设置为正面开口的结构，所述拍面刀模内部固定设置有若干个方形冲切刃以及若干个圆形冲切刃，所述拍面刀模背面固定设置有若干个排气脱模管，本实用新型通过刀模主体、方形冲切刃和圆形冲切刃上端设置为锐角薄刃结构，下端设置为逐渐变窄且与上端通过平滑圆弧过渡的结构，避免材料表层撕裂，保障了软夹层的物理性能，同时通过排气脱模管远离拍面刀模的一端设置为半开口结构，切割时可以及时排出空气，防止空气形成气阻导致切割面出现褶皱，保证了切割质量。
