Description

Technical Field

[0001] The utility model belongs to the technical field of drying for injection molded part coating, and particularly relates to a drying device for injection molded part coating. Background Technique

[0002] The drying device for injection molded part coating plays a crucial role in the production process of injection molded parts. This drying device mainly heats air and makes the hot air circulate, accelerating the drying process of the coating or coating layer applied on the surface of the injection molded parts. Usually, methods such as electric heating, steam heating or hot blast stove are used to generate heat sources. After heating the air to a certain temperature, the hot air is evenly blown onto the surface of the injection molded parts through a fan or air duct system. The hot air contacts the coating layer, takes away the moisture and solvents in it, and makes it dry and solidify quickly;

[0003] For the drying of injection molded part coating, the injection molded parts to be dried are placed in a drying chamber of a certain size for drying. Due to the different production of injection molded parts, the sizes of various injection molded parts to be dried are different, and the size of the drying chamber is mostly fixed and cannot be adjusted conveniently. Therefore, the coating drying of injection molded parts of different sizes cannot be uniformly dried, and thus the versatility and flexibility of the equipment during use are not high enough;

[0004] To solve the above problems, a drying device for injection molded part coating is proposed in this application. Content of the Utility Model

[0005] To solve the above problems existing in the prior art, the utility model provides a drying device for injection molded part coating, which has the characteristic of being able to uniformly dry the coatings of injection molded parts of different sizes.

[0007] As a preferred technical solution of the present utility model, two support columns are fixedly connected to the bottom surface of the housing, and a stabilizing ring is fixedly connected to the bottom end of each support column.

[0008] As a preferred technical solution of the present utility model, an opening and closing door is movably hinged to the left side surface of the housing, and an observation plate is clamped to the inner wall of the opening and closing door.

[0009] As a preferred technical solution of the present utility model, a support rod arranged at equal distances is fixedly connected to the upper surface of the inner ring of the first rotating bearing, and the top end of each support rod is fixedly connected to the bottom surface of one of the placement racks.

[0010] As a preferred technical solution of the present utility model, two fixing pins are arranged above the second rotating bearing, and the bottom end of each fixing pin penetrates through the inner ring of the second rotating bearing and is in contact with the upper surface of the outer ring of the second rotating bearing.
