Technical Field

[0001] The present application relates to the technical field of injection molding processing, and in particular to an injection molding gate cutting machine. Background Art

[0002] Injection molded parts are formed by demolding from liquid organic solutions. However, after demolding, a protruding gate is left on the surface. Most traditional processing methods are to cut the gates on the injection molded parts one by one using manual handheld cutting equipment, and the entire process is fixed by holding the injection molded parts. Not only is the processing efficiency low and inconvenient to operate, but during the cutting process, the hands of personnel are too close to the cutting equipment, which can easily cause injuries to the hands and has low safety.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0022] In the description of the present application, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0023] Embodiment

[0024] In order to solve the problems of low working efficiency and high risk coefficient in the existing technology for gate cutting of injection molded blank, referring to Figure 1 and Figure 2 as shown, the present application discloses an injection molding gate cutting machine, including: a machine table 10, an XYZ axis moving platform 20, a workpiece loading table 30, and an ultrasonic cutter 40;

[0025] The XYZ axis moving platform 20 and the workpiece loading table 30 are arranged above the machine table 10 along the Y-axis direction, and a groove 31 is opened on the lower surface of the workpiece loading table 30 along the X-axis direction;

[0026] Above the workpiece loading table 30, two product fixtures 50 are arranged along the X-axis direction. The product fixtures 50 are provided with dropping grooves 52 extending through the workpiece loading table 30 corresponding to the positions of the gates of the injection molded blanks;

[0027] The ultrasonic cutter 40 is arranged on the XYZ axis moving platform 20 and is driven to move in the XYZ axis directions by it.

[0028] In this embodiment, a fixture groove 51 for placing the injection molded blank is opened inside the product fixture 50. Positioning posts 53 for positioning the injection molded blank are arranged on both sides in the X-axis direction inside the fixture groove 51. Pneumatic rotary chucks 54 are respectively arranged inside the product fixtures 50 corresponding to both sides in the X-axis direction of the fixture groove 51. During the placement of the injection molded blank, the positioning posts 53 will position the injection molded blank and the pneumatic rotary chucks 54 on both sides will act to rotate and automatically clamp the injection molded blank. In this way, the injection molded blank will not shift in position during the cutting process, thereby avoiding damage to the injection molded blank by the ultrasonic cutter 40.

[0029] In order to achieve the automatic recycling of the gate waste after cutting, a waste recycling pipeline 60 is arranged inside the groove 31 along the X-axis direction in this application. A waste recycling bin 70 is arranged below the end of the conveying end of the waste pipeline to the end of the machine table 10. During actual use, the gate cut off by the ultrasonic cutter 40 from the injection molded blank will automatically fall onto the waste recycling pipeline 60 and automatically fall into the waste recycling bin 70 under the conveyance of the waste recycling pipeline 60 for unified recycling, avoiding the subsequent automatic collection problem of the operator and reducing the labor intensity of the operator.

[0030] Specifically, the XYZ-axis moving platform 20 of this application includes an X-axis slide table arranged on the machine table 10 and driven to move by an X-axis lead screw module 21, a Y-axis slide table arranged on the X-axis slide table and driven to move by a Y-axis lead screw module 22, and a Z-axis slide table arranged on the Y-axis slide table and driven to move by a Z-axis lead screw module 23. Driven by the X-axis lead screw module 21, the Y-axis lead screw module 22, and the Z-axis lead screw module 23, the ultrasonic cutting device of this application can achieve XYZ-axis movement, so as to achieve the separate cutting of the injection molded gate in the two product fixtures 50.

[0031] In this embodiment, the ultrasonic cutter 40 of this application includes an ultrasonic generating device 41 arranged on the Z-axis slide table and a cutting tool 42 connected to the ultrasonic generating device 41. When cutting the injection molded gate, the ultrasonic generating device 41 will drive the cutting tool 42 to vibrate and can cut it off from the injection molded blank when it contacts the injection molded gate.

[0032] In addition to the above structure, a carrier plate 90 is also arranged at the bottom of the Z-axis slide table in this application, and a vision detection camera 80 is arranged on the carrier plate 90. When cutting the injection molded gate, the vision detection camera 80 needs to detect and position the injection molded gate.

[0033] To sum up, the working process of the present utility model will be briefly described below:

[0034] The operator first places the injection molded blank on a single product fixture 50 (during the placement process, the positioning posts 53 in the fixture groove 51 will position the injection molded blank, and the pneumatic rotary chucks 54 located on both sides inside the product fixture 50 will automatically clamp the injection molded blank). The XYZ-axis moving platform 20 drives the ultrasonic cutter 40 and the vision inspection camera 80 to move along the XYZ-axis direction. During this process, after the vision inspection camera 80 takes a photo to position the gate on the injection molded blank, the XYZ-axis moving platform 20 then drives the ultrasonic cutter 40 to the gate hole to perform automatic cutting on it. During the above operations, the operator can place the injection molded blank to be cut on another product fixture 50, and after the gate cutting of the injection molded blank in the previous product fixture 50 is completed, the gate cutting can be performed on the next injection molded blank according to the above operation process.
