Background
In the existing temperature controller housing forming die technology, the die structure is often designed relatively simply, which results in low forming efficiency. Such inefficiency not only affects the overall output of the production line, but can also lead to product quality instability, thereby adversely affecting the production process.
In the prior art, the mounting and dismounting operations of the upper mold core and the lower mold core are generally complicated. This may be due to insufficient handling convenience in the design of the mold or insufficient fixing and positioning mechanisms of the mold. Such cumbersome operations not only extend production preparation time, but may also result in increased equipment downtime, thereby reducing the flexibility and efficiency of the production line. In some cases, such cumbersome operations may also increase the labor intensity of the operator, and may even cause operational errors or safety accidents.
In demolding a molding die, it is generally necessary to take out the molding die manually in the prior art. This means that the operator has to open the mould and manually remove the formed thermostat housing. Since the molding grade is located inside the mold, the take-out process may be spatially limited and inconvenient to operate. This not only reduces work efficiency, but also may increase the working strength of operators, and may even cause damage to the product during the removal process, affecting the quality of the product.
