[0002] With the rapid popularization of office automation and intelligent printing technology, the market demand for printers, as core output devices, continues to rise. As the protective and supporting structure of the whole machine, the molding quality of the printer shell directly affects the appearance accuracy, assembly compatibility, and usage stability of the product. Due to its advantages of high efficiency and mass production, injection molding has become the mainstream manufacturing method for printer shells. In the injection molding production process, the demolding device is a key piece of equipment connecting injection molding and subsequent processing. Its demolding effect directly determines whether the shell has defects such as scratches, deformation, and residues. Therefore, high-performance demolding devices for printer shell injection molding are needed to ensure production continuity and product qualification rate.

[0003] However, existing demolding devices are not convenient for fixing injection molds during use, which makes the molds prone to displacement and shaking during demolding, affecting the continuity and stability of the demolding action and reducing overall production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a demolding device for injection molding of printer housing. By setting a fixing part, it solves the problem that existing demolding devices are not convenient to fix the injection mold during use, which leads to displacement and shaking of the mold during demolding, affecting the continuity and stability of the demolding action and reducing the overall production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a demolding device for injection molding of printer housings, comprising a support table and further comprising: a fixing part mounted on the support table; a demolding part disposed below the support table; the fixing part comprising a drive assembly mounted on the top of the support table; the fixing assembly disposed on the support table; the drive assembly comprising a support plate fixedly connected to the top of the support table, a rotating shaft rotatably connected to the rear side of the support plate, a drive rod fixedly connected to the outer wall of the rotating shaft, two connecting rods hinged to the drive rod, and a power component disposed on the support table; the two connecting rods are arranged in a circumferential array, and the power component comprising a motor bracket fixedly connected to the rear side of the support table, a motor fixedly connected to the inner wall of the motor bracket; the output shaft of the motor is fixedly connected to the rotating shaft via a coupling.

[0006] Furthermore, the demolding section includes a power assembly disposed below the support table; and a plurality of demolding components, each mounted on the power assembly; there are three demolding components.

[0007] Furthermore, the fixing component includes two limiting slide grooves formed on the support plate, each of the two limiting slide grooves is slidably connected to a fixing plate, and each of the two fixing plates is fixedly connected to a transmission rod on its rear side. The two connecting rods are respectively hinged to the two transmission rods; the two limiting slide grooves are mirror images of each other.

[0008] Furthermore, the power assembly includes several circular holes formed on the support table, a U-shaped bracket is fixedly connected to the top inner wall of the support table, an electric telescopic rod is fixedly connected to the bottom of the U-shaped bracket, the output end of the electric telescopic rod passes through the U-shaped bracket, the output end of the electric telescopic rod is slidably connected to the U-shaped bracket, and a rectangular plate is fixedly connected to the output end of the electric telescopic rod; three circular holes are provided, and each corresponds to one of the three demolding components.

[0009] Furthermore, the demolding assembly includes a hollow cylinder fixedly connected to the top of the rectangular plate. A circular limiting plate is slidably connected to the inner wall of the hollow cylinder. A cylindrical rod is fixedly connected to the top of the circular limiting plate.

[0010] This utility model has the following beneficial effects: 1. By setting a fixing part, when in use, the mold is placed on the top of the support table. After starting the motor, through the linkage of the rotating shaft, drive rod, connecting rod and transmission rod, combined with the guiding effect of the limit slide, the two fixing plates are driven to move closer to each other, thereby fixing the mold, keeping it stable during demolding, avoiding displacement and shaking, ensuring smooth demolding action, and improving demolding efficiency. 2. By setting up a demolding section and activating the electric telescopic rod, the hollow cylinder is pushed upward by the rectangular plate. The hollow cylinder, through the circular limiting plate, drives the circular plate on the cylindrical rod to pass through the circular hole and push the printer shell inside the mold upward. At the same time, the circular plate pushes the circular limiting plate through the cylindrical rod to compress the spring. The elastic force generated by the spring deformation realizes the slow ejection of the printer shell, completing the demolding operation. The demolding action is smooth and gentle, which can avoid scratches, deformation or buckle breakage of the shell due to excessive force, and ensure the molding quality of the shell.

[0018] The demolding section 3 includes a power assembly 31, which is located below the support table 111; and several demolding components 32, each mounted on the power assembly 31. There are three demolding components 32. The power assembly 31 includes several circular holes 311 formed in the support table 111. A U-shaped bracket 312 is fixedly connected to the inner top wall of the support table 111. An electric telescopic rod 313 is fixedly connected to the bottom of the U-shaped bracket 312. The output end of the electric telescopic rod 313 passes through the U-shaped bracket 312 and is slidably connected to the U-shaped bracket 312.

[0019] It should be noted that the control of the motor 216 and the electric telescopic rod 313 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0020] A specific application of this embodiment is as follows: During use, the mold is placed on top of the support table 111, and the motor 216 is started. The motor 216 drives the drive rod 213 to rotate via the rotating shaft 212. The drive rod 213 drives two transmission rods 223 to move via two connecting rods 214. Under the action of the two transmission rods 223 and the two limiting slide grooves 221, the two fixing plates 222 slide and move closer to each other within their respective limiting slide grooves 221, thus fixing the mold. The electric telescopic rod 313 is then started. The electric telescopic rod 313 pushes the hollow cylinder 321 upward via the rectangular plate 314. The hollow cylinder 321 pushes the circular plate 324 on the cylindrical rod 323 through the circular limiting plate 322, moving it towards the corresponding... The circular hole 311 moves upward and pushes out the printer housing inside the mold. During this process, the circular plate 324 pushes the circular limiting plate 322 through the cylindrical rod 323 to compress the spring 325, causing it to deform and generate a corresponding elastic force. Under the action of the spring 325, the printer housing is slowly pushed out of the mold, thus demolding. When it is necessary to remove the mold from the support table 111, the reverse drive motor 216 releases the fixation of the mold. The reverse drive electric telescopic rod 313 drives the hollow cylinder 321 to move downward through the rectangular plate 314. The compressive force of the spring 325 disappears and the elastic force is released. The elastic force acts on the circular limiting plate 322, causing the cylindrical rod 323 to drive the circular plate 324 to reset.
