Abstract
Description
Technical Field
[0001] This utility model relates to the field of housing injection molding technology, and in particular to a power adapter housing injection molding device. Background Technology
[0002] The power adapter housing injection molding unit, as a key link in the plastic molding manufacturing system, operates by transforming granular plastic raw materials into a molten state at high temperatures, and then injecting them into a carefully designed mold cavity under high pressure. After cooling and shaping, it finally produces a power adapter housing that meets high-precision standards. The unit bears the important responsibility of accurately and efficiently transforming basic plastic materials into product components with specific functions and appearances, and occupies an irreplaceable key position in the electronic equipment manufacturing process.
[0003] In the early stages, power adapter housing injection molding equipment was mainly based on plunger-type structures, with a low overall level of automation, heavily reliant on manual operation and semi-automatic assistance. Now, through innovative layered injection technology, the injection volume and distribution of each layer of material can be precisely controlled, greatly improving product performance and appearance, while effectively optimizing raw material utilization efficiency and reducing production costs. However, during injection molding, the upper and lower molds are used in conjunction, and a lot of time is wasted during demolding, resulting in discontinuous production and low efficiency. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a power adapter housing injection molding device, which aims to improve the problem in the prior art where the upper and lower molds are used together, resulting in a lot of wasted time during demolding, leading to discontinuous production and low efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power adapter housing injection molding device, including a base, a lower mold mechanism provided on the top surface of the base, a bracket fixedly connected to the edge of the top surface of the base, an upper mold mechanism provided at the upper end of the bracket, the upper mold mechanism being used for mold closing injection molding, and a positioning mechanism provided on the outer wall of the bracket.
[0006] The lower mold mechanism includes a fixing component, which is disposed on the top of the base. A motor is fixedly connected to the inner wall of the base. The output end of the motor passes through the fixing plate and is fixedly connected to a central shaft. A rotating plate is fixedly connected to the top of the central shaft. Multiple rotating components are disposed on the outer wall of the rotating plate. A lower mold base is disposed at the other end of the rotating components.
[0007] The upper mold mechanism includes a hydraulic rod, which is disposed on the top of the base. The bottom of the hydraulic rod passes through the top of the bracket and is fixedly connected to the upper mold base. An injection molding assembly is disposed on the top of the upper mold base, and a positioning assembly is disposed on the outer wall of the upper mold base.
[0008] The fixing component includes a fixing plate, which is fixed to the top surface of the base, and the outer wall of the fixing plate is fixedly connected with meshing teeth.
[0009] The rotating assembly includes a rotating shaft, one end of which is rotatably connected to the outer wall of the rotating disk, and the other end of which is fixedly connected to the lower mold base. Gears are provided on the outer wall of the rotating shaft.
[0010] The injection molding assembly includes an injection port, with an injection port provided on one side of the top surface of the upper mold base and an vent provided on the other side of the top surface of the upper mold base.
[0011] The positioning component includes a positioning ring, which is fixed to the outer wall of the upper mold base, and a plurality of positioning posts are fixedly connected to the outer wall of the lower mold base.
[0012] The positioning mechanism includes an infrared transmitter, which is disposed at the lower end of the outer wall of the bracket, and an infrared receiver is disposed on the outer wall of the lower mold base.
[0013] The top surface of the base is provided with a collection groove, and the top of the fixing plate is provided with a clearance opening.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, when producing the power adapter housing, the motor is started, and the motor drives the rotating disk to rotate. When a lower mold base rotates to the bottom of the bracket, the infrared receiver receives the signal from the infrared receiver, the rotating disk stops rotating, and the upper mold mechanism operates to perform injection molding. After injection molding is completed, the motor continues to drive the rotating disk to rotate, and the next lower mold base enters for processing. The processed lower mold base rotates out. When the processed lower mold base reaches the meshing teeth, the meshing teeth mesh with the gear, causing the lower mold base to flip. In conjunction with the demolding component inside the lower mold base, the completed workpiece is unloaded. The number of teeth of the meshing teeth is the same as the number of teeth of the gear, so that the lower mold base rotates one revolution and returns to the top surface of the fixed disk for the next round of injection molding.
[0016] 2. In this utility model, when the lower mold base rotates to the lower position of the upper mold base, the hydraulic rod is activated to press the upper mold base downwards, and with the assistance of the positioning pin, the lower mold base and the upper mold base are fully engaged. Then, material is poured into the mold cavity between the lower mold base and the upper mold base through the injection port, and the air in the mold cavity is discharged through the vent. After cooling and molding, the hydraulic rod is activated to lift the upper mold base, and the molded shell is left in the lower mold base. The lower mold base is carried out by the rotation of the rotating disk, and the next lower mold base enters the processing. This continuous operation realizes uninterrupted processing and greatly speeds up production efficiency. Attached Figure Description

[0034] Working principle: When producing the power adapter casing, the motor 202 is started, which drives the rotating disk 204 to rotate. When a lower mold base 206 rotates to the bottom of the bracket 4, the infrared receiver 502 receives the signal from the infrared receiver 502, and the rotating disk 204 stops rotating. The upper mold mechanism 3 operates to perform injection molding. After injection molding is completed, the motor 202 continues to drive the rotating disk 204 to rotate, and the next lower mold base 206 enters for processing. The processed lower mold base 206 rotates out. When the processed lower mold base 206 reaches the meshing tooth 2012, the meshing tooth 2012 meshes with the gear 2052, causing the lower mold base 206 to flip. With the help of the demolding component inside the lower mold base 206, the completed workpiece is unloaded. The number of teeth of the meshing tooth 2012 is the same as the number of teeth of the gear 2052, so that the lower mold base 206 rotates one revolution and returns to the top surface of the fixed disk 2011 for the next round of injection molding.
[0035] When the lower mold base 206 rotates to the lower mold base 303, the hydraulic rod 301 is activated, pressing the upper mold base 303 downwards. The positioning ring 3041 and positioning pin 3042 assist in positioning, ensuring that the lower mold base 206 and the upper mold base 303 are fully engaged. Then, material is poured into the mold cavity between the lower mold base 206 and the upper mold base 303 through the injection port 3021, and the air in the mold cavity is discharged through the vent port 3022. After cooling and molding, the hydraulic rod 301 is activated to lift the upper mold base 303. The molded shell is left inside the lower mold base 206, which is then carried out by the rotation of the rotating disk 204. The next lower mold base 206 then enters the processing, allowing for continuous operation and uninterrupted processing, which greatly accelerates production efficiency.
