How to make a pair of turnover box molds? Choose the right steel for the mold base and core cavity. For example, if you want to produce a pair of turnover box molds, you need to use hardened pre-hardened steel as a template, and then select appropriate mold standard parts. Secondly, the hardness of each piece of steel must be well controlled and not too hard.
Then, the friction and guiding part of the turnover box mold must be completed, and manual operation is not allowed. If you need to inject a durable turnover box, you must use a low-melt index HDPE material, such as plastic with an index of 4 or 6.
Secondly, we must ensure that the cooling system achieves the best results. In order to make the two durable hydraulic drives automatically eject with the machine, the eject action during mold opening can be smoother. For different types of molds, precise mold processing is required to ensure the accuracy of mold operation, otherwise the mold cannot have high-speed running performance and the cooling water channel design on the largest molding surface of the mold must be optimized.
What should I pay attention to for a pair of good turnover box molds?
Our design team will consider the cooling system of the mold, because the cooling system is related to the molding cycle and directly affects production efficiency and production costs. We use circulating water to reduce cooling time, improve production efficiency, and reduce production costs.
Turnover box molds do not have very high requirements on the surface of the product, so when selecting steel materials, only suitable mold steel materials need to be selected. Commonly used P20 and 718H mold steel materials can meet the requirements.
The design of the exhaust system should also be considered. We have designed an excellent exhaust solution at the key position of mold injection molding. For example, the plastic inlet of the one-time forming turnover box is at the bottom, and most of them are hot runner gates. This not only allows the turnover box to be formed faster, but also saves a lot of gate material by using the hot runner. Using mold flow analysis software in design can improve the success rate of turnover box mold design and manufacture, and effectively ensure product quality.
Mold design is a key point when making the turnover box mold. The design of the turnover box mold cooling system is the most important, because the cooling system is related to the turnover box molding cycle and directly affects the production cost. In addition, the design of the cooling system is a complex task, not only the cooling effect and cooling uniformity must be considered, but also the influence of the cooling system on the overall structure of the mold.
