Description

Technical Field

[0001] This utility model relates to the field of LCD screen housing injection molding technology, specifically to an LCD screen housing injection molding device. Background Technology

[0002] As an important component for protecting the screen and improving the durability and aesthetics of the device, the LCD screen casing requires the use of corresponding injection molding equipment during the production and processing of existing LCD screen casings.

[0003] Existing LCD screen housing injection molding equipment works by closing a fixed mold and a movable mold, then feeding material into the mold cavity to form the workpiece. After molding, the movable mold is opened, and the workpiece is removed. However, before re-closing the mold for injection molding, the mold cavity needs to be cleaned. Currently, cleaning is done manually by hand-held spray guns, which results in incomplete cleaning and affects the cleaning effect. Therefore, we propose an injection molding device for LCD screen housing production. Utility Model Content

[0004] The purpose of this invention is to provide an injection molding device for the housing of LCD screen production, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an injection molding device for the outer shell of an LCD screen, comprising a platform, a fixed mold fixedly installed on one side of the top of the platform, a movable mold attached to one side wall of the fixed mold, and a drive assembly connected to the outer wall of the movable mold;

[0006] A bracket is fixedly installed on one side wall of the platform, and an electric actuator is fixedly installed on the top of the bracket. The actuator rod moves through the bracket and is fixedly connected to an adjustment plate. A hollow vertical plate is connected to the bottom of the adjustment plate, and air nozzles are fixedly connected to both sides of the vertical plate.

[0007] By adopting the above technical solution, the material is first injection molded after the fixed mold and moving mold are closed. After molding, the moving mold is opened and the material is unloaded. The electric push rod drives the adjusting plate to descend, so that the vertical plate is placed between the moving mold and the fixed mold. Then, the gas in the vertical plate is discharged through the air nozzle and blown towards the moving mold and the fixed mold, thereby achieving cleaning. The adjusting plate can drive the vertical plate to move back and forth along its length, which helps to improve the comprehensiveness of cleaning and thus improve the cleaning effect.

[0008] In a preferred embodiment of this utility model, the driving assembly includes a fixed plate, which is fixed to one side of the top of the platform. A hydraulic cylinder is fixedly connected to the middle of the inner side wall of the fixed plate, and the outer end of the hydraulic cylinder is fixedly connected to the moving mold. Limiting rods are fixed at the four corners of one side wall of the fixed plate, and the limiting rods movably pass through the moving mold and are fixedly connected to the fixed mold.

[0009] By adopting the above technical solution, the moving mold can be moved by the hydraulic cylinder, thereby realizing the opening and closing of the moving mold, and the limit rod can limit the trajectory of the moving mold, which helps to improve the accuracy of the closing of the moving mold and the fixed mold.

[0010] In a preferred embodiment of this utility model, the bottom of the adjusting plate is provided with a sliding groove, and a lead screw motor is fixedly installed on one end face of the inner cavity of the sliding groove. A lead screw is fixedly connected to the outer end of the drive shaft of the lead screw motor. The outer end of the lead screw is rotatably connected to the inner wall of the sliding groove. A suitable lead screw slider is fitted on the outer wall of the lead screw, and the bottom of the lead screw slider is connected to the vertical plate.

[0011] By adopting the above technical solution, the lead screw is driven to rotate by the lead screw motor, thereby driving the lead screw slider to move back and forth along the length direction of the adjustment plate, thus realizing the reciprocating movement of the vertical plate.

[0012] In a preferred embodiment of this utility model, a servo motor is fixedly embedded at the bottom of the lead screw slider, and the outer end of the servo motor drive shaft is fixedly connected to the middle of the top of the vertical plate.

[0013] By adopting the above technical solution, the servo motor can drive the vertical plate to reciprocate at a small angle, thereby making the air distribution more uniform during air blowing. At the same time, during unloading, the direction of the air nozzle can be adjusted to align with the air between the workpiece and the mold, so that the gas impact enters the gap to assist unloading and cool the workpiece.

[0014] In a preferred embodiment of this utility model, a feeding pipe is fixedly connected to the back of the fixed mold.

[0015] In a preferred embodiment of this utility model, an air supply pipe is fixedly connected to one side wall of the vertical plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The present application discloses an injection molding device for the housing of an LCD screen production. The device uses an electric push rod to drive a vertical plate to descend, thereby lowering the vertical plate between the fixed mold and the moving mold. Then, gas is discharged through the nozzle to perform air blowing cleaning on the fixed mold and the moving mold. Furthermore, the adjusting plate can drive the hollow plate to move back and forth along its length, which helps to improve the comprehensiveness of cleaning and thus improve the cleaning effect.

[0018] The servo motor can drive the air distribution plate to rotate slightly at a small angle, which helps to improve the uniformity of air blowing and thus further improve the cleaning effect.

[0019] When the moving mold and the fixed mold are opened for unloading, the hollow plate moves to one end of the adjusting plate and the angle is adjusted to align with the gap between the workpiece and the mold. This allows the workpiece to be demolded quickly using air blowing power and also enables the workpiece to be cooled. Attached Figure Description
