Description

Technical Field

[0001] This utility model relates to the field of rapid application technology of wear-resistant coating for molds, specifically a rapid spraying device for wear-resistant coating on mold surfaces. It is suitable for spraying wear-resistant coatings on the surfaces of various small molds such as small household appliance molds, hardware molds, and plastic molds, and can significantly improve the surface performance of molds and extend their service life. Background Technology

[0002] In industrial production, molds, as key forming tools, are subjected to complex conditions such as high pressure, friction, and alternating hot and cold temperatures for extended periods. This makes their surfaces prone to wear, corrosion, and fatigue, leading to a shortened lifespan and requiring frequent replacement or repair. This not only increases production costs but also severely impacts production efficiency. To address this issue, the industry typically applies a wear-resistant coating to the mold surface to improve its hardness, wear resistance, corrosion resistance, and high-temperature resistance.

[0003] Currently, existing mold surface coating equipment has several shortcomings. First, its coating efficiency is low. Traditional equipment often uses a single spray gun for manual operation, resulting in long coating times for large or complex molds, making it difficult to meet the needs of mass production. Second, the coating uniformity is poor. Affected by factors such as the operator's skill level, the speed and angle control of the spray gun, the coating thickness is prone to deviation, and some areas may even experience missed or thin coatings, affecting the surface strengthening effect of the mold. Third, the coordination between heating and curing is poor. Mold preheating and coating curing are mostly completed by independent equipment, and temperature loss can easily occur during mold transfer, leading to a decrease in the adhesion between the coating and the mold surface. Fourth, the dust collection effect is poor. The large amount of dust generated during the coating process not only pollutes the environment but also harms the health of operators. Existing dust removal equipment is unable to achieve efficient dust collection and filtration. Fifth, the degree of automation is low. Equipment parameter adjustment and coating process monitoring mostly rely on manual operation, resulting in large errors and the inability to achieve real-time recording and traceability of production data.

[0004] Therefore, developing a rapid spraying equipment for wear-resistant coatings on mold surfaces with high spraying efficiency, good coating uniformity, excellent heat curing synergy, good dust collection effect, and high degree of automation has become an urgent technical problem to be solved in the current mold surface treatment field.

Once the machine starts operating, opening the regulating valve 76 allows spraying to begin. The mold rotates automatically, ensuring even spraying and saving manpower and resources while improving work efficiency. Adjusting the nozzle allows for precise control of the spraying speed of the wear-resistant coating. After one coat of spraying, the mold must be completely dry before the next coat can be applied. At this time, controlling the control switch group 2 starts the fan 82 and the electric heating tube 83. The air blown by the fan 82 passes through the electric heating tube 83, raising its temperature. The ventilation opening on the right side of the drying chamber 81 allows the hot air to be precisely delivered to the mold surface, while also preventing people from touching the electric heating tube 83, improving safety. This effectively and quickly dries the mold, facilitating the next coat of spraying, saving time and improving spraying efficiency.
