[0015] Figure 1 It is a schematic structural diagram of a plastic part injection molding machine convenient for material taking according to the present invention.

[0016] Figure 2 For Figure 1 It is a schematic diagram after removing the moving mold assembly and the fixed mold assembly. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present invention will be further described in detail below with reference to the drawings. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so they cannot be understood as limiting the protection scope of the present invention; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0018] Such as Figure 1-2As shown in the figure, an injection molding machine for plastic parts that facilitates material taking includes an injection molding machine body. The injection molding machine body includes a fixed mold assembly 1 and a moving mold assembly 2 that are arranged opposite to each other. One side of the fixed mold assembly is connected to the injection molding machine body and is used to form products after the product raw materials discharged from the injection molding machine body go through sequential injection and cooling procedures. The moving mold assembly is arranged opposite to the fixed mold assembly and can reciprocate relative to the fixed mold assembly, and is used to eject the formed products so that they freely fall to the product collection place. It also includes a receiving hopper 3. The receiving hopper is arranged at the product collection place. The receiving hopper has a receiving bin with an upper opening. A moving structure 4 for driving the receiving hopper to move is installed at the product collection place.

[0019] In this way, after the fixed mold assembly and the moving mold assembly of the injection molding machine body are closed to form plastic parts, the moving mold assembly separates from the fixed mold assembly. The moving mold assembly ejects the formed products, and the products freely fall into the receiving bin at the product collection place. When the products in the receiving bin reach a certain quantity, the moving structure moves the receiving bin outwards, that is, the material taking of the products is completed. It has high safety, high automation degree and is convenient to use.

[0020] Specifically, the specific structure of the injection molding machine body belongs to the prior art and will not be described in detail here.

[0021] During implementation, the moving structure includes a moving plate 5, a screw rod 6 and two vertically arranged columns 7. The screw rod is connected to the columns through bearings. One end of the screw rod passes through the column and is fixedly connected to the output shaft of a servo motor 8. The servo motor is fixedly installed on the column. A nut block 9 is threadedly connected to the screw rod. The nut block is fixedly connected to the moving plate. A guide rod 10 is fixed between the two columns. A guide block 11 is slidably fitted on the guide rod. The guide block is fixedly connected to the moving plate. Two support arms 12 are fixed on the moving plate. A rotating shaft is rotated on the support arm. The rotating shaft is fixedly connected to the receiving hopper. One of the rotating shafts is fixedly connected to the output shaft of a rotating motor 13. The rotating motor is fixedly installed on the support arm.

[0022] In this way, the servo motor drives the screw rod to rotate. Under the action of the guide rod, it drives the receiving hopper to move outwards to the outside of the injection molding machine body. Then the rotating motor drives the rotating shaft to rotate, and further drives the receiving hopper to flip, so that the products in the receiving hopper fall, and then drives the receiving hopper to reset.

[0023] Specifically, a conveyor belt is arranged on one side of the injection molding machine body. When the receiving hopper reaches above the conveyor belt, the receiving hopper flips and the products fall on the conveyor belt.

[0024] During implementation, there are two guide rods which are symmetrically arranged on both sides of the screw rod. This improves the stability.

[0025] During implementation, it also includes two baffles 14, which are located on both sides of the product collection area. One end of the baffle is fixedly connected to the fixed mold assembly, and a support column 5 is fixedly installed downward at the other end of the baffle. It is convenient to block the product so that the product can fall better into the aggregate hopper.

[0026] During implementation, two guide plates 16 are fixedly installed at the lower end of the baffle. The lower ends of the two guide plates are close to each other, and a material guide opening 17 is formed at the lower ends of the two guide plates. It is convenient to guide the falling process of the product.

[0027] Finally, it should be noted that those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalents, the present utility model also intends to include these changes and modifications.
