The turnover box is mainly used to transport various products, so it is also called the logistics box. According to the different products to be transported, the turnover boxes mainly include the following categories: fruit turnover boxes, fish turnover boxes, industrial products turnover boxes, bottle turnover boxes, bread turnover boxes, etc. This secondary injection molding design guides turnover boxes for different purposes Details such as shape design, overlay effect, load-bearing strength, and production cost need to be considered.

　　The cooling of the turnover box mold is very important. A reasonable cooling system can reduce the deformation of the product and shorten the injection molding cycle. The size of the waterway diameter and the even distance of the arrangement need to be precise. If the diameter of the water channel is too small, the cooling is not timely, and the mold temperature is too high, the product will be deformed, thereby increasing the production cycle and reducing production efficiency.

　　The structure of the turnover box mold is mostly fixed mold four-slide core pulling. Such a design can make the perimeter of the turnover box draw smoothly without scratching the surface of the product, and can also control the size of the mold, thereby reducing the cost of the mold.

　　For the gate design of the turnover box mold, we can choose a hot runner or a cold runner. Cold runners are recommended if the return material will be added to the plastic material. The large gate is placed in the center of the bottom of the turnover box to prevent the gate from being blocked. If the turnover box is produced with new materials, it is recommended to select multiple hot runners, which can not only reduce the waste of redundant runners but also reduce the process of shearing the runner gates. For the number of points of the hot runner, it is generally 2, 4, 6, or more points into the gate, and finally selected according to the structural design and weight of the product.
