These inlet holes 16 are connected to the external coolant supply system to ensure that the coolant can flow into the mold stably and continuously; after the coolant enters the mold through the inlet holes 16, it needs to be evenly distributed inside the mold; therefore, the design of the inlet holes 16 usually takes into account the flow path and distribution range of the coolant to ensure that all parts of the mold can be fully cooled; by adjusting the size, number and position of the coolant inlet holes 16, the cooling intensity of the mold can be adjusted; this helps to optimize the cooling effect and improve product quality according to factors such as the injection molding material, mold size and product structure; the drain holes 17 are responsible for discharging the coolant inside the mold. During the injection molding process, as the mold temperature rises, the coolant will absorb and take away the heat of the mold. When the coolant reaches a certain temperature or flow rate, it needs to be discharged in time through the drain holes 17 to avoid adverse effects on the mold; the drain holes 17 are connected to the external coolant recovery and treatment system to form a complete cooling cycle. The coolant discharged through the drain hole 17 can be recovered, filtered and reused, thereby reducing production costs and environmental pollution; by adjusting parameters such as the flow rate, temperature and pressure of the coolant, precise control of the mold temperature can be achieved, which helps to ensure temperature stability during the injection molding process, improve the dimensional accuracy and surface quality of the product, and thus improve product quality and production efficiency.
