The butter bottle cap mold is a matching mold for industrial butter bottles. The formed bottle caps need to have excellent sealing and impact resistance to prevent butter leakage and contamination. The mold is designed for the threaded structure of the bottle cap and the sealing ring. It adopts a threaded core and cavity to ensure that the bottle cap fits tightly with the bottle body without leakage. The cavity is treated with S136 die steel, featuring a high surface finish. The formed bottle caps have no flash or shrinkage marks, and both appearance and performance are excellent. The gating system is designed with a point gate, and the gate is located at the top of the bottle cap. The ejection mechanism adopts pipe pushing for ejection, ensuring uniform force distribution and preventing thread deformation.
