Description

Technical Field

[0001] This utility model relates to the field of edge trimming technology for injection molded shell parts, and more particularly to edge trimming mechanisms for injection molded shell parts. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and shapes, shapes ranging from simple to complex, sizes ranging from large to small, precise product dimensions, easy product updates and replacements, and the ability to produce complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products.

[0003] Furthermore, the outer shell of some equipment is also made by injection molding. After injection molding, the outer shell needs to be trimmed, which is usually done manually. Manual trimming takes a long time and increases the processing cost.

[0004] Therefore, it is necessary to provide a trimming mechanism for injection-molded housing parts to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a trimming mechanism for injection-molded shell parts, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a trimming mechanism for injection-molded shell parts, comprising a device body, a mounting frame mounted on the top surface of the device body, a cutting table on the top surface of the device body, a cavity platform on the top surface of the cutting table, a first driving cylinder vertically mounted on the top surface of the mounting frame, a mounting plate through which the output end of the first driving cylinder passes, a driving frame at one end of the mounting plate, and a cutting blade at the bottom end of the driving frame. By using the first driving cylinder, driving frame, cutting blade, cutting table, and cavity platform in coordination, trimming of the injection-molded shell is facilitated after molding. During operation, the operator places the injection-molded shell upside down on the cavity platform (the cavity platform fits the injection-molded shell), then activates the first driving cylinder, causing it to drive the cutting blade downwards via the driving frame, thereby trimming the injection-molded shell. This method is simple to operate, changes the traditional manual trimming method, and greatly improves work efficiency.

[0007] Preferably, a second drive cylinder is vertically mounted at the middle of the top surface of the mounting frame. An extrusion plate is provided through the output end of the second drive cylinder and is located inside the drive frame. By using the second drive cylinder and the extrusion plate in conjunction, the stability of the injection-molded shell is improved during edge trimming. After the injection-molded shell is inverted on the cavity table, the second drive cylinder is activated, and then the second drive cylinder drives the extrusion plate to move downward, thereby pressing and fixing the extrusion plate to the top surface of the injection-molded shell. This method is simple to operate and facilitates improved stability during edge trimming.

[0008] Preferably, the top surface of the cutting table is provided with a cutting groove on the outside of the cavity table. By providing the cutting groove, it is convenient to make way for the cutting blade and to facilitate the trimming of the injection-molded shell.

[0009] Preferably, there are two first drive cylinders, and the two first drive cylinders are symmetrically installed about the center line of the mounting frame. By setting two first electric drives, the stability of the drive frame when moving up and down can be improved.

[0010] Preferably, a rubber pad is provided on the bottom surface of the extrusion plate. By providing the rubber pad, the extrusion plate is prevented from making hard contact with the injection-molded shell, which facilitates the protection of the injection-molded shell.

[0011] Preferably, the device body is provided with support feet at the bottom end, and multiple support feet are provided. The multiple support feet are installed at equal intervals at the four corners of the bottom end of the device body. By providing support feet, it is convenient to support the device body, thereby improving the stability of the device body during operation.

[0012] Preferably, a controller is installed on the outer surface of the device body, which facilitates the control of the electrical components inside the device body.

[0013] Compared with related technologies, the edge-cutting mechanism for injection-molded shell parts provided by this utility model has the following beneficial effects:

[0014] Compared with existing technologies, the edge trimming mechanism for injection-molded shell parts, through the coordinated use of a first drive cylinder, drive frame, cutting blade, cutting table, and cavity table, facilitates edge trimming after the injection-molded shell is formed. During operation, the operator inverts the injection-molded shell onto the cavity table (the cavity table fits the injection-molded shell), then activates the first drive cylinder, which drives the cutting blade downwards via the drive frame, thus trimming the injection-molded shell. This method is simple to operate, changing the traditional manual trimming method and greatly improving work efficiency. Secondly, the coordinated use of a second drive cylinder and extrusion plate enhances the stability of the injection-molded shell during edge trimming. After the injection-molded shell is inverted onto the cavity table, the second drive cylinder is activated, which then drives the extrusion plate downwards, thus pressing and fixing the extrusion plate against the top surface of the injection-molded shell. This method is simple to operate and improves the stability during edge trimming.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] First Embodiment

[0024] Please refer to the following: Figure 1-4The edge trimming mechanism for injection-molded shell parts includes a device body 1. A mounting frame 5 is mounted on the top surface of the device body 1. A cutting table 2 is mounted on the top surface of the device body 1. A cavity platform 10 is mounted on the top surface of the cutting table 2. A first drive cylinder 6 is vertically mounted on the top surface of the mounting frame 5. A mounting plate 11 is mounted through the surface of the mounting frame 5 at the output end of the first drive cylinder 6. A drive frame 3 is mounted at one end of the mounting plate 11. A cutting blade 8 is mounted at the bottom end of the drive frame 3. By using the first drive cylinder 6, drive frame 3, cutting blade 8, cutting table 2, and cavity platform 10 in coordination, edge trimming of the injection-molded shell is facilitated after molding. During operation, the operator places the injection-molded shell upside down on the cavity platform 10 (the cavity platform 10 fits the injection-molded shell), then activates the first drive cylinder 6, causing it to drive the cutting blade 8 downwards via the drive frame 3, thereby trimming the injection-molded shell. This method is simple to operate, changes the traditional manual edge trimming method, and greatly improves work efficiency.

[0025] The working principle of the trimming mechanism for the injection-molded shell part provided by this utility model is as follows:

[0026] The edge-trimming mechanism for injection-molded shell parts utilizes a combination of a first drive cylinder 6, a drive frame 3, a cutting blade 8, a cutting table 2, and a cavity table 10. This facilitates edge trimming after the injection-molded shell is formed. During operation, the operator places the injection-molded shell upside down onto the cavity table 10 (the cavity table 10 fits snugly against the injection-molded shell), then activates the first drive cylinder 6. This cylinder, via the drive frame 3, moves the cutting blade 8 downwards, trimming the injection-molded shell. This method is simple to operate, significantly improving efficiency compared to traditional manual trimming. Furthermore, the combination of a second drive cylinder 7 and an extrusion plate 12 enhances the stability of the injection-molded shell during edge trimming. After the injection-molded shell is placed upside down on the cavity table 10, the second drive cylinder 7 is activated, moving the extrusion plate 12 downwards until it presses and fixes the top surface of the injection-molded shell. This method is also simple to operate and improves stability during edge trimming.

[0027] Compared with related technologies, the edge-cutting mechanism for injection-molded shell parts provided by this utility model has the following beneficial effects:

[0028] In operation, the edge-cutting mechanism for injection-molded shell parts involves the operator placing the injection-molded shell upside down on the cavity table 10 (the cavity table 10 fits snugly against the injection-molded shell). Then, the first drive cylinder 6 is activated, causing it to move the cutting blade 8 downwards via the drive frame 3, thus trimming the injection-molded shell. This method is simple to operate, changing the traditional manual edge-cutting method and greatly improving work efficiency. Furthermore, the coordinated use of the second drive cylinder 7 and the extrusion plate 12 enhances the stability of the injection-molded shell during edge-cutting. After the injection-molded shell is placed upside down on the cavity table 10, the second drive cylinder 7 is activated, causing the extrusion plate 12 to move downwards, thus pressing and fixing the extrusion plate 12 against the top surface of the injection-molded shell. This method is simple to operate and improves the stability during edge-cutting.

After the injection molded shell is inverted on the cavity table 10, the second drive cylinder 7 is activated, and then the second drive cylinder 7 drives the extrusion plate 12 to move downward, so that the extrusion plate 12 is pressed and fixed to the top surface of the injection molded shell.
