Detailed Implementation
[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0019] Example 1: like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the injection molding part trimming device. Figure 2 This is a structural diagram of the collection tank. Figure 3This is a structural schematic diagram of a T-shaped plate. This utility model provides an injection molding part finishing device, including a base 101, a support 102, and a dust removal assembly. The dust removal assembly includes an arc-shaped box 103, a fixing plate 104, a plug-in plate 105, a sealing plate 106, a perforated plate 107, a connecting pipe 108, a blower 109, an installation pipe 110, a collection component, and a clamping component. The collection component includes a collection tank 111 and a filter screen 112. The clamping component includes a servo electric cylinder 113, a connecting seat 114, a left clamping plate 115, a right clamping plate 116, and a driving component. The driving component includes a T-shaped plate 117 and a drive motor 118. This solution solves the problem that existing equipment cannot handle the dust generated during grinding and finishing, and that floating dust can easily be inhaled by operators, causing harm. It is understood that the aforementioned solution can handle the dust generated during processing.
[0020] In this embodiment, a support seat 102 is fixedly installed on the base 101. The support seats 102 are symmetrically arranged and fixed by positioning pins and countersunk bolts. The induced draft fan 109 directly adopts existing technology that meets the requirements for dust removal, such as the equipment disclosed in the prior art CN222021289U. In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this utility model does not involve the improvement of software and methods.
[0021] The arc-shaped box 103 is symmetrically welded with the fixing plate 104 at its bottom. The plug-in plate 105 is detachably connected to the fixing plate 104 and welded onto the base 101. The sealing plate 106 is installed on the left side of the arc-shaped box 103. The perforated plate 107 is welded onto the arc-shaped box 103. The connecting pipe 108 is welded onto the sealing plate 106 and communicates with the internal cavity of the arc-shaped box 103. The induced draft fan 109 is installed on the outlet side of the connecting pipe 108. The mounting pipe 110 is installed on the outlet side of the induced draft fan 109. The collecting component is located on the outlet side of the mounting pipe 110. The clamping component is located on the support base 102. The arc-shaped outer cavity of the arc-shaped box 103 will not interfere with the rotation of the plastic part. The perforated plate 107 is welded and fixed, allowing dust to enter the inner cavity of the arc-shaped box 103 after passing through. The end of the arc-shaped box 103 away from the sealing plate 106 is a sealed structure. The sealing plate 106 is fixed by bolts and connected to the connecting pipe 108. The housing of the induced draft fan 109 is provided with a connecting flange for easy fixing of the air inlet and outlet ends. The mounting pipe 110 is provided with an externally threaded cylinder end for easy installation of the collecting component. The clamping component is used to clamp the workpiece and rotate it to achieve angle adjustment.
[0022] Secondly, the collection tank 111 is threadedly connected to the mounting pipe 110 and is located on the outlet side of the mounting pipe 110; the filter screen 112 is installed on the outlet side of the collection tank 111. The installation port of the collection tank 111 is directly connected to the external thread end on the mounting pipe 110 for installation, and can be directly removed after subsequent rotation. The filter screen 112 is fixed to the outlet side of the collection tank 111 by bolts, which facilitates the blocking of dust and makes the dust concentrated in the collection tank 111, but allows air to pass through freely.
[0023] Then, the servo cylinder 113 is fixed on the support base 102; the connecting base 114 is connected to the output end of the servo cylinder 113; the left clamping plate 115 is set on the left connecting base 114 through the driving component; the right clamping plate 116 is rotatably mounted on the right connecting base 114. The servo cylinder 113 is fixed by bolts, and a disc is connected to its output end by countersunk bolts. The disc is connected to the connecting base 114 by bolts. The left clamping plate 115 is driven to rotate by the driving component. The mounting shaft of the right clamping plate 116 is directly mounted on the connecting base 114 through a rotating bearing. Anti-slip pads are respectively glued and fixed to the contact surfaces of the left clamping plate 115 and the right clamping plate 116 with the plastic parts to improve stability.
[0024] Finally, the T-shaped plate 117 is detached from the connecting seat 114 on the left side; the drive motor 118 is fixed on the T-shaped plate 117, and its output shaft is connected to the left clamping plate 115 via a coupling. The T-shaped plate 117 is fixed by positioning pins and bolts. The drive motor 118 is a servo motor with a brake mechanism and an encoder, which facilitates stopping the shaft locking and controlling the rotation angle. It is fixed on the T-shaped plate 117 by bolts, and its output shaft is connected to the connecting shaft end of the left clamping plate 115 via a coupling.
[0025] To address the problem of existing equipment's inability to handle dust generated during grinding and finishing, and the potential for operator inhalation of floating dust causing injury, this invention addresses the issue of plastic parts being placed between the left clamping plate 115 and the right clamping plate 116 during processing. Then, the servo cylinders 113 on both sides are controlled to move the left and right clamping plates 115 and 116 closer together to clamp the workpiece. The workpiece processing angle can then be adjusted by controlling the drive motor 118, and the exhaust fan 109 is simultaneously activated. A handheld grinder can be used to grind the edges of the workpiece. When the blower 109 is working, it generates suction. At this time, the grinding dust will enter the internal cavity of the arc-shaped box 103 through the perforated plate 107, and be transported to the collection component through the connecting pipe 108 and the mounting pipe 110. Finally, the dust-free air is discharged after being processed by the collection component, and the dust is collected in a concentrated manner. This solves the problem that existing equipment cannot handle the dust generated during grinding and finishing, and the floating dust is easily inhaled by the operator, causing physical harm.
[0026] Example 2: like Figure 4 As shown, where Figure 4 This is a schematic diagram of the overall structure of the injection molding part trimming device. Based on the first embodiment, this utility model provides an injection molding part trimming device, which further includes a support assembly, including a lower support 201 and a limiting seat 202.
[0027] The lower support 201 is detachably connected to the left-side support 102 and slidably connected to the collection tank 111; the limiting seat 202 is slidably connected to the collection tank 111 and detachably connected to the lower support 201. The fixed end of the lower support 201 is connected to the left-side support 102 by bolts and has an arc-shaped cavity that fits against the outer wall of the collection tank 111. The limiting seat 202 is connected to the lower support 201 by bolts.
[0028] In this embodiment, the lower support 201 and the limiting seat 202 will improve the working stability of the collection tank 111.
[0029] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
