Description

Technical Field

[0001] This utility model relates to the field of display frame manufacturing technology, specifically to a display frame injection mold. Background Technology

[0002] The monitor frame is a crucial component of the monitor's structure, primarily referring to the frame surrounding the display screen. It typically works together with the screen, back cover, and stand to form a complete monitor. It secures the display screen and internal components such as circuit boards and backlight modules, ensuring stability and preventing movement. It provides physical protection for the screen, preventing direct impacts from external forces.

[0003] Injection molds are used in the production of plastic monitor frames. Utility model patent CN222473217U discloses a break-resistant monitor frame injection mold, belonging to the field of injection mold technology. It includes a base with a liquid reservoir inside, a lower mold mounted above the base, a support column connected to the base, a top plate connected to one end of the support column, and a hydraulic push rod mounted on the top plate. The movable end of the hydraulic push rod is connected to an upper mold. This break-resistant monitor frame injection mold uses cooling pipes to evenly distribute coolant within the lower mold, uniformly absorbing heat and improving the molding effect of the monitor frame. When the hydraulic push rod pushes the upper mold downwards, an insert rod is inserted into a slot, and the upper mold also presses down on a fitting block, causing the fitting block to embed into a fitting groove and compressing a connecting spring. When the upper mold moves upwards, the connecting spring rebounds, pushing the fitting block and causing it to disengage the molding plate from the molding groove, thus facilitating the removal of the monitor frame by workers.

[0004] However, with this common display frame injection mold, after injection molding and mold closing, it is necessary to wait for the product to cool down and remove the product before the next injection molding operation can be carried out. Therefore, a display frame injection mold is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a display mid-frame injection mold that has advantages such as reducing waiting time and increasing production efficiency. It solves the problem that with common display mid-frame injection molds, after injection molding and mold closing, it is necessary to wait for the product to cool down and be removed before the next injection molding operation can be carried out.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A display frame injection mold includes a mounting base plate, two support plates fixedly mounted on the top of the mounting base plate, a shifting assembly disposed between the two support plates, two injection molds mounted on the shifting assembly, a support seat fixedly mounted on the top of the mounting base plate, an mounting base fixedly mounted on the top of the support seat, and an injection molding machine slidably mounted on the top of the mounting base.

[0008] The repositioning assembly includes a rotating shaft rotatably mounted between the two supporting uprights. A rotating base is fixedly mounted on the surface of the rotating shaft. End plates are fixedly mounted on both ends of the rotating shaft. Injection molds are symmetrically arranged on the two mutually distant sides of the rotating base.

[0009] Furthermore, a mounting top plate and a fixed bottom plate are fixedly installed on both sides of the rotating base that are far apart from each other, and four guide rods are fixedly installed between the mounting top plate and the fixed bottom plate.

[0010] Furthermore, a movable plate is slidably mounted on the surface of the guide rod, and the injection mold is set between the fixed base plate and the movable plate.

[0011] Furthermore, the injection mold includes a fixed mold fixedly installed on one side of the fixed base plate, and a movable mold fixedly installed on one side of the movable plate.

[0012] Furthermore, a rotating motor is fixedly installed on one side of one of the supporting uprights, and the output shaft of the rotating motor is fixedly connected to one end of the rotating shaft.

[0013] Furthermore, a mold-closing cylinder is fixedly installed on one side of the mounting top plate, and the movable end of the mold-closing cylinder is fixedly installed on one side of the movable plate.

[0014] Furthermore, the top of the mounting base is provided with a sliding groove, and a docking screw is rotatably installed on the inner side wall of the sliding groove.

[0015] Furthermore, a docking base is slidably installed on the inner side wall of the sliding groove, the injection molding machine is fixedly installed on the top of the docking base, the docking base is threadedly connected to the docking screw, and a docking motor is fixedly installed on one side of the mounting base, the output shaft of the docking motor is fixedly connected to one end of the docking screw.

[0016] Compared with the prior art, the present invention provides a display frame injection mold, which has the following advantages:

[0017] 1. This monitor frame injection mold solves the problem that, in common monitor frame injection molds, after injection molding and mold closing, the product needs to be cooled and removed before the next injection molding operation can be performed. The two injection molds are installed on a shifting assembly, and the rotating shaft rotates, causing the rotating base to rotate and the two injection molds to shift. After shifting, the injection molding machine moves on top of the mounting base and docks with one of the injection molds for injection molding. The operator then cools and removes the product from the other injection mold.

[0018] 2. The injection mold for the display frame has a connecting screw installed inside the mounting base. The connecting motor drives the connecting screw to rotate, which in turn moves the connecting base and the injection molding machine, allowing the output end of the injection molding machine to connect and separate from the input end of the fixed mold.
