Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, and in particular to a feeding hopper for an injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Current technology suffers from the problem of uneven material feeding when too much plastic raw material is added, affecting the machine's feeding. This is typically addressed by manually stirring the material at the bottom of the feeding hopper, a cumbersome process that needs improvement. Furthermore, the commonly used vertical internal stirring structure leads to dispersed material feeding, resulting in uneven discharge, and also causes uneven mixing ratios when using multiple materials. Utility Model Content

[0003] The purpose of this invention is to provide a feeding hopper for an injection molding machine, which solves the problem of smooth feeding in ordinary injection molding machines.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a feeding hopper for an injection molding machine, including a feeding hopper body structure, a feeding front cavity connected to the feeding hopper body structure, and an extrusion screw disposed in the feeding front cavity. The feeding hopper body structure includes a collection bin and a feeding hopper body, a segmented feeding pipeline at the upper end of the collection bin, a rotary stirring structure disposed in the feeding hopper body, and a vibration device mounting frame structure disposed at the side end of the feeding hopper body. The segmented feeding pipeline includes an upper material distribution joint group, a centralized feeding pipeline connected to the lower part of the upper material distribution joint group, and a discharge port group disposed at the lower part of the centralized feeding pipeline. The bottom of the feeding hopper body is provided with a docking expansion pipe, which is connected to the feeding front cavity.

[0005] The rotary stirring structure includes a mounting hole on the side of the feed hopper, a drive motor outside the mounting hole, and a built-in drive shaft structure inside the feed hopper and connected to the drive motor.

[0006] The built-in drive shaft structure includes a drive stirring shaft and stirring blocks arranged alternately on the upper part of the drive stirring shaft.

[0007] The vibration equipment mounting frame structure includes an equipment mounting frame located at the bottom end of the feed hopper and a locking seat connected to the equipment mounting frame.

[0008] A motor stabilizing mounting frame is provided on the upper part of the feed hopper outside the mounting hole.

[0009] A blower is provided at the bottom of the collection bin, and a corrugated plate for material discharge is installed on the inner wall of the collection bin.

[0010] The beneficial effects of this utility model are as follows: This utility model can prevent material from clogging the discharge channel by using a segmented feeding pipeline. The rotating shaft driven by the motor can control the rotation of the spiral blades, thereby adjusting the material feeding speed and preventing material from clogging the discharge channel. Furthermore, the use of the blowing port, the corrugated plate for material discharge, and the motor stable mounting frame can ensure that the material smoothly enters the front feeding cavity, thereby improving the product qualification rate.

[0017] The terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end" used in the application text to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1, such as Figure 1-4 As shown, a feeding hopper for an injection molding machine includes a feeding hopper body structure, a feeding front cavity 1 connected to the feeding hopper body structure, and an extrusion screw 2 disposed in the feeding front cavity. The feeding hopper body structure includes a collection bin 3 and a feeding hopper body 4, a segmented feeding pipeline at the upper end of the collection bin, a rotary stirring structure disposed in the feeding hopper body, and a vibration device mounting frame structure disposed on the side of the feeding hopper body.
