This cavity structure can enable the product and the mold to be quickly demolded. As Figure 5 shown, this cavity structure requires the design of sliders, straight ejectors, and inclined ejectors to ensure the integrity of the product. Due to the large height difference in the length and height of the product, the heights of the sliders, straight ejectors, and inclined ejectors are very high, which will greatly increase the overall cost of the mold.
