Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a temperature control mechanism for a toilet seat production mold. Background Technology

[0002] In the manufacturing process of smart toilets, the toilet seat is a crucial component, and its structural design involves multiple factors. Smart toilet seats typically house electronic components, and to accommodate these components while maintaining the original dimensions of the toilet seat, manufacturers tend to reduce its thickness. However, this design requirement presents certain challenges during the injection molding process.

[0003] Existing toilet seat manufacturing molds use standard injection molding technology. During the injection process, the gap between the upper and lower molds is small. This design means that when molten material is injected into the mold, it tends to fill only the middle part of the mold. When the molten material moves halfway through the mold, due to the small gap, some of the molten material can cool directly, resulting in some areas of the mold not being completely filled with molten material. This problem not only affects the integrity of the mold but may also lead to defects in the size, strength, and appearance of the final toilet seat.

[0004] To address this issue, the present invention provides a temperature control mechanism for a toilet seat production mold. Summary of the Invention
