Description

Automatic material taking mechanism and molding injection molding equipment

Technical Field

The utility model relates to the technical field of injection molding equipment, in particular to an automatic material taking mechanism and molding injection molding equipment.

Background Art

Molding injection molding equipment is injection molding equipment, also known as injection molding, which is a molding method of injection and molding. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and then cooled and solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods. The temperature of the molded product is high and it is located inside the mold. Manual removal not only has low work efficiency, but also poses safety hazards.

Chinese patent publication number CN217098759U discloses an automatic in-mold product removal device. The rotary drive mechanism can remove the molded product in the injection mold when driving the material removal mechanism to rotate 90°, and rotate the product to a horizontal state when the rotary drive mechanism drives the material removal mechanism to reset. When the XYZ-axis drive machine drives the rotary drive mechanism and the material removal mechanism to move outward above the injection mold, the molded product can be horizontally lowered to the assembly line for transportation. Compared with the transmission injection mold material removal method, the utility model greatly improves the work efficiency and reduces the labor intensity of the operator.

However, the above patent has the following shortcomings:

The automatic product taking device only uses a suction cup to absorb the product from the upper surface of the product. When the product is rotated and moved, the product is easy to fall off the suction cup, causing damage to the product.
