[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The material storage device of the injection molding machine is one of the key components in the injection molding process. Its main function is to store and melt plastic raw materials, and inject the molten plastic into the mold with precise pressure and speed when needed.

[0003] Most of the existing storage devices only provide storage functions and lack filtering of plastic raw materials. The plastic raw materials in the storage barrel may contain impurities due to raw materials or environmental problems. These impurities enter the mold and easily affect product quality. Some storage devices with filters are not convenient for cleaning and replacing the filters. In addition, the discharge pipe of the storage device may cause the plastic raw materials to solidify on the inner wall of the pipe due to weather reasons, which in turn affects the stability of the discharge and reduces the practicality of the storage device.

DETAILED DESCRIPTION

[0023] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0024] like Figure 1 and Figure 2 As shown, the utility model provides an injection molding storage device for an injection molding machine, comprising a storage barrel 1, a heating plate 2 installed on the inner wall of the storage barrel 1, and an inlet pipe 3 and an outlet pipe 4 respectively arranged at the top edge and the middle of the bottom of the storage barrel 1, wherein the inlet pipe 3 is used to guide the input of plastic raw materials, and the outlet pipe 4 is used to discharge the plastic raw materials in the storage barrel 1 into the injection mold;

[0025] The material storage barrel 1 is equipped with a stirring frame 5, and the inlet pipe 3 and the outlet pipe 4 are both connected to the inner side of the material storage barrel 1. The stirring frame 5 movably passes through the inner top of the material storage barrel 1 and is connected to the bottom output shaft of the motor 6. The motor 6 is locked and fixed on the top of the material storage barrel 1.

[0026] In this embodiment, a valve 7 is installed on the discharge pipe 4 to control the on-off of the plastic raw material in the discharge pipe 4;

[0027] When in use, the lower end of the discharge barrel 81 is connected to the feed port of the injection molding machine mold, and the plastic raw material is injected into the storage barrel 1 through the feed pipe 3 to provide protection for the plastic raw material through the storage barrel 1, and the stirring frame 5 can be driven to rotate by starting the motor 6, and the plastic raw material can be heated by starting the heating plate 2 to prevent the plastic raw material from hardening in the storage barrel 1. The plastic raw material in the storage barrel 1 can be discharged outward after opening the valve 7, and the discharged material is guided to the filter screen 87 by the guide plate 82, and the impurities in the plastic raw material are filtered out by the filter screen 87, and the filtered plastic raw material is discharged downward into the injection molding machine mold.

[0028] like Figure 3 and Figure 4 As shown, the present embodiment also includes an auxiliary mechanism 8 disposed below the storage barrel 1, the auxiliary mechanism 8 includes a discharge barrel 81 connected to the bottom of the discharge pipe 4, a heating component disposed at the outer end of the discharge pipe 4, used to heat the discharge pipe 4 to reduce the solidification of the plastic raw material in the discharge pipe 4, a guide plate 82 disposed in the middle of the inner side of the discharge barrel 81, and a partition frame 84 disposed below the guide plate 82 and connected to the inner side wall of the discharge barrel 81;

[0029] The guide plate 82 is rotatably connected to the inner side of the discharge barrel 81 via a rotating shaft 810. The guide plate 82 can swing left and right in the discharge barrel 81 to guide the plastic raw materials to different filter screens 87.

[0030] A sliding frame 85 is provided on the left and right sides of the partition frame 84, and a filter screen 87 for filtering the plastic raw material is installed in each sliding frame 85. The sliding frame 85 is movably connected to the inner side of the opening 86 opened on the discharge barrel 81, and the sliding frame 85 can slide left and right inside the opening 86 to realize the placement and removal of the filter screen 87;

[0031] The rotating shaft 810 vertically moves through the front end surface of the discharge cylinder 81;

[0032] In this embodiment, the rotating shaft 810 is a T-shaped structure, and the rotating shaft 810 protrudes from the front end surface of the discharge barrel 81, so that the rotating shaft 810 can be rotated to adjust the angle of the guide plate 82 to guide the plastic raw material to change the flow direction;

[0033] In this embodiment, a strip groove is provided at one end of the sliding frame 85 away from the partition frame 84, so that the sliding frame 85 can be moved outward by pulling the strip groove.

[0034] In this embodiment, a butterfly bolt 83 is provided at the front end of the guide plate 82. When the upper end of the guide plate 82 rotates to fit the inner wall of the discharge barrel 81, the front end of the guide plate 82 will fit tightly with the rear end of the butterfly bolt 83, and at this time, the lower end of the guide plate 82 is located above the filter screen 87, so that the butterfly bolt 83 can squeeze the upper end of the guide plate 82 to reduce the random shaking of the guide plate 82 and improve the stability of the guide plate 82.

[0035] In this embodiment, the front end surface of the discharge barrel 81 is provided with two screw holes, which correspond to the left and right tilting states of the guide plate 82 respectively, and the inner circle of the screw hole cooperates with the butterfly bolt 83, so that the butterfly bolt 83 cooperates with different screw holes to press and fix the guide plate 82 in different states;

[0036] The filter screen 87 is an upwardly convex arc structure, which facilitates the impurities on the filter screen 87 to roll toward the edge, thereby reducing the impurities from clogging the top of the filter screen 87;

[0037] When in use, when a filter screen 87 needs to be cleaned or replaced, it can be detached from the discharge barrel 81 by rotating the butterfly bolt 83, and then the rotating shaft 810 is rotated to drive the guide plate 82 to rotate. When the guide plate 82 rotates to fit the other inner wall of the discharge barrel 81, the rotating shaft 810 cannot be rotated. At this time, the lower end of the guide plate 82 is located above another filter screen 87 that does not need to be cleaned or replaced. Then, the butterfly bolt 83 is rotated and inserted into another screw hole on the discharge barrel 81, and the guide plate 82 is pressed tightly by the butterfly bolt 83. The guide plate 82 is fixed to reduce the shaking of the guide plate 82, and the plastic raw material in the discharge pipe 4 is guided by the guide plate 82 to another filter screen 87, and the sliding frame 85 is pulled to drive the filter screen 87 to move outward and away from the discharge barrel 81, so that the filter screen 87 can be cleaned or replaced. After cleaning or replacement, the sliding frame 87 drives the filter screen 87 to be inserted into the opening 86 for continued use. Alternatively, a threaded hole can be selectively opened at the edge of the discharge barrel 81, and the sliding frame 87 can be pressed and fixed with external bolts to further improve the stability of the sliding frame 87 and the filter screen.

[0038] like Figure 3 As shown, the heating assembly in this embodiment includes a fixed cover 88 mounted on the discharge pipe 4 and a heating wire 89 installed in the fixed cover 88. The discharge pipe 3 can be heated by the heating wire 89 to reduce the solidification of the plastic raw material in the discharge pipe 3, which is conducive to the stable discharge of the plastic raw material.
