Description

Technical Field

[0001] The utility model relates to the field of injection molding machines, in particular to a drying and mixing device suitable for injection molding machines. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is a main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It can heat plastic and apply high pressure to the molten plastic so that it can be ejected and fill the mold cavity. The working process of the injection molding machine includes steps such as plastic melting, injection, cooling and mold opening. It first heats and melts the plastic raw material, and then pushes the molten plastic into the mold through the screw in the injection cylinder to fill the entire mold cavity. Next, the molten plastic cools and solidifies in the mold to form a plastic product. Finally, the mold is separated and the finished product is taken out of the mold.

[0003] Injection molding machines are widely used in various fields such as medical equipment, auto parts, mechanical parts, defense industry, telecommunication engineering, transportation, instrumentation industry, electrical and electronic, aviation, construction, agriculture and daily life.

[0024] By setting the batching plate 22 and the block 24 , when the ingredients on the batching plate 22 reach a certain weight, the batching plate 22 pushes the block 24 away and tilts, and the ingredients on the top of the batching plate 22 fall into the mixing drum 33 at the bottom.

[0025] The stirring assembly 3 includes a stirring rod 31 which is vertically rotatable and arranged at the top of the inner wall of the outer shell 1. A stirring frame 32 is arranged on the surrounding side of the stirring rod 31. A stirring drum 33 is arranged at the top of the inner wall of the outer shell 1 and outside the stirring frame 32. The top of the stirring drum 33 and the top of the outer shell 1 are connected to a feed pipe 34.

[0026] The stirring rod 31 is driven to rotate by the rotation of the output end of the stirring motor 35, and then the stirring frame 32 is driven to rotate, so that the ingredients placed therein are fully stirred and mixed.

[0027] A baffle 25 is provided at the top of the inner wall of the batching box 21 and above the batching plate 22, a spring 26 is provided on the right side of the block 24, and a rotating block 27 is threadedly connected to the inner side of the slot 23 and at the right end of the spring 26 so as to be movable left and right.

[0028] When the proportion of ingredients needs to be adjusted, the rotating block 27 is driven to move toward the inner wall of the ingredient box 21 by rotating, thereby pushing the spring 26 to be further compressed, making the block 24 more difficult to be pushed, thereby adjusting the proportion of ingredients.

[0029] A button 28 is provided at the bottom of the left side of the inner wall of the batching box 21, and a winding disk 29 is rotatably provided at the top of the right side of the inner wall of the batching box 21, and the inner side of the winding disk 29 is fixedly connected to the right side of the top of the batching plate 22 by a rope.
