[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Understandably, referring to Figure 1 , Figure 2 and Figure 5The sprue removal device of this utility model includes a cutting mechanism 100 and a positioning mechanism 200. The cutting mechanism 100 includes a frame 110, a cutter 120 and a drive assembly (not shown in the figure). The drive assembly is connected to the frame 110, and the cutter 120 is connected to the movable end of the drive assembly. The drive assembly is used to drive the cutter 120 to move in order to cut the injection molded part. The positioning mechanism 200 includes a fixing block 210, a stop block 220 and a screw 230. The fixing block 210 is fixedly connected to the frame 110. The fixing block 210 has a cavity 211 for accommodating the injection molded part. The cavity 211 matches the injection molded part. The screw 230 is threadedly connected to the fixing block 210. The stop block 220 is rotatably connected to the screw 230 and can be located at the end of the cavity 211.

[0028] A fixing block 210 is fixedly connected to the frame 110. The fixing block 210 has a cavity 211, the shape of which matches the shape of the injection molded part. The injection molded part is placed in the cavity 211, and then a drive block 220 is driven to rotate on the screw 230, so that the drive block 220 moves to the end of the cavity 211, thereby positioning the injection molded part in the cavity 211, preventing the injection molded part from shaking and improving the positional stability of the injection molded part. A drive assembly is connected to the frame 110, and a cutter 120 is connected to the movable end of the drive assembly. The drive assembly drives the cutter 120 to move towards the fixing block 210, so that the cutter 120 can cut off the sprue of the injection molded part, thereby replacing manual hand-held pliers operation, reducing labor intensity, improving the quality of sprue removal, and increasing cutting efficiency.

[0029] In addition, the screw 230 and the fixed block 210 are threadedly connected. By driving the screw 230 to rotate, the screw 230 can be screwed into or out of the fixed block 210, which facilitates the adjustment of the position of the screw 230. This allows the stop block 220 to slide along the axial direction of the screw 230, thereby adjusting the position of the stop block 220 along the axial direction of the screw 230. This makes it easier to adapt to the size of the workpiece and improves its applicability.

[0030] Specifically, the drive assembly may include a gear, a rack, and a lever. The gear is rotatably connected to the frame 110, the rack is slidably connected to the frame 110, and the gear and rack mesh. The lever is fixedly connected to the gear, and the cutter 120 is fixedly connected to the rack. By moving the lever, the lever can drive the gear to rotate, so that the rack and the cutter 120 can move synchronously, so that the cutter 120 can move to cut off the sprue of the injection molded part.

[0031] Specifically, the drive assembly can also be a linear cylinder, electric actuator, linear slide module, or other drive element that can drive the cutter 120 to move linearly, so that the cutter 120 can cut off the sprue of the injection molded part. No limitation is made here.

[0032] Understandably, referring to 1 and Figure 4A chamfer 221 is provided between the end face and the side wall of the stop block 220. The chamfer 221 is located on the side of the stop block 220 near the cavity 211 and can abut against the injection molded part. The chamfer 221 between the end face and the side wall of the stop block 220 allows the chamfer 221 to abut against the injection molded part when the stop block 220 rotates around the screw 230. By providing the chamfer 221, the injection molded part can be smoothly guided to slide within the cavity 211, so that the injection molded part fits tightly against the inner wall of the cavity 211, thereby stabilizing the injection molded part within the cavity 211, improving the positional stability of the injection molded part, and improving the quality of gate removal. In addition, the chamfer 221 can prevent the stop block 220 from getting stuck on the injection molded part when rotating, allowing the stop block 220 to rotate smoothly on the screw 230, facilitating the loading of the injection molded part, improving the convenience of operation, and speeding up the removal efficiency.

[0033] Understandably, referring to Figure 2 and Figure 3 The cutting mechanism 100 also includes a guide block 130, which is fixedly connected to the fixed block 210. The guide block 130 has a guide groove 131, and the cutter 120 is slidably connected in the guide groove 131. The guide block 130 is fixedly connected to the fixed block 210. By opening the guide groove 131 on the guide block 130 and slidably connecting the cutter 120 to the guide groove 131, the cutter 120 can slide stably along the length direction of the guide groove 131, making the movement trajectory of the cutter 120 smooth, thereby improving the accuracy and stability of the cutting.

[0034] In addition, the cutter 120 is located in the guide groove 131, which can limit the movement direction of the cutter 120, prevent the cutter 120 from shaking or deviating during the cutting process, reduce the cutting error of the gate, and improve the cutting quality of the gate and the yield of injection molded parts.

[0035] Specifically, refer to Figure 2 and Figure 3 The guide block 130 is fitted with a first fastener 132, which is threadedly connected to the fixing block 210. The first fastener 132 passes through the guide block 130 and is threadedly connected to the fixing block 210, allowing the guide block 130 to be easily fixed to the fixing block 210, reducing positional offset. Furthermore, the first fastener 132 facilitates the disassembly and assembly of the guide block 130, making maintenance and replacement easier and extending the service life of the sprue removal device.

[0036] It should be noted that the first fastener 132 can be a bolt, screw, etc., and is not limited here.

[0037] Specifically, the number of first fasteners 132 is set to multiple, and the multiple first fasteners 132 are arranged at intervals. The connection strength of the guide block 130 can be improved by the multiple first fasteners 132, so as to prevent the guide block 130 from loosening or shifting during the cutting process, thereby improving the cutting accuracy of the cutting mechanism 100.

[0038] Understandably, referring to Figure 2 and Figure 3 The cutting mechanism 100 also includes a mounting base 140, which is fixedly connected to the movable end of the drive assembly. The cutter 120 is detachably connected to the mounting base 140. The mounting base 140 is fixedly connected to the movable end of the drive assembly. By allowing the cutter 120 to be detachably connected to the mounting base 140, the removal and replacement of the cutter 120 is facilitated without replacing the entire cutting mechanism 100, reducing maintenance costs. Furthermore, the cutter 120 and the mounting base 140 are easily separated, facilitating individual cleaning and maintenance, and helping to extend their service life.

[0039] In addition, by setting the cutter 120 to be detachably connected to the mounting base 140, different types of cutters 120 can be quickly replaced according to different cutting needs, adapting to the cutting requirements of different injection molded parts, thus improving the versatility and applicability of the device.

[0040] Specifically, refer to Figure 2 and Figure 3 The mounting base 140 has a mounting groove 141, in which the cutter 120 is inserted. A second fastener 142 passes through the mounting base 140, located within the mounting groove 141, and through which the cutter 120 passes. The mounting base 140 has a mounting groove 141, in which the cutter 120 is inserted. The second fastener 142 passes through the cutter 120 and is connected to the mounting groove 141. This makes the installation and removal of the cutter 120 faster and more convenient, and enhances the connection stability between the cutter 120 and the mounting base 140. It also ensures that the cutter 120 remains stable even when encountering impact or vibration during cutting, preventing it from shaking and falling off, thus improving the accuracy and safety of the cutting process.

[0041] The second fastener 142 can be a pin, bolt, screw, etc., and there is no limitation here.

[0042] It should be noted that the cutter 120 fits snugly against the inner wall of the mounting groove 141, so that the cutter 120 can be stably placed in the mounting groove 141, reducing the positional wobbling of the cutter 120. When the cutter 120 cuts off the sprue of the injection molded part, the inner wall of the mounting groove 141 can provide sufficient support for the cutter 120, preventing the cutter 120 from wobbling and improving the quality of the cut.

[0043] Understandably, referring to Figure 2 and Figure 5 The frame 110 includes a base 111, an adjusting rod 112, and an adjusting block 113. The adjusting rod 112 is fixedly connected to the base 111, the adjusting block 113 is slidably connected to the adjusting rod 112, a fixed block 210 is fixedly connected to the base 111, and a drive assembly is connected to the adjusting block 113. By driving the adjusting block 113 to slide on the adjusting rod 112, the distance between the drive assembly and the fixed block 210 can be easily adjusted, thus adapting to different injection molded parts, expanding the applicability of the sprue removal device, and improving its applicability.

[0044] It should be noted that the adjusting block 113 has an adjusting hole and an opening (not shown in the attached figure). The opening extends from the side wall of the adjusting block 113 to the adjusting hole, so that the adjusting hole and the opening communicate. The adjusting rod 112 passes through the adjusting hole, so that the adjusting block 113 can slide along the axial direction of the adjusting rod 112. A bolt passes through the opening, and a nut is threaded onto the bolt. By screwing the nut into the bolt, the bolt and nut can cooperate to reduce the gap of the opening, so that the side wall of the adjusting hole can be pressed against the adjusting rod 112, and the adjusting block 113 can be locked onto the adjusting rod 112. This allows for convenient adjustment of the position of the adjusting block 113 and improves the flexibility of adjustment.

[0045] Understandably, referring to Figure 5 The fixing block 210 has a relief groove 212, into which the cutter 120 can extend. The drive assembly can drive the cutter 120 to move, so that the cutter 120 can extend into the relief groove 212, thereby enabling the cutter 120 to cut off the sprue of the injection molded part, separating the sprue from the injection molded part, and allowing the sprue to fall onto the relief groove 212, thus guiding the direction of the sprue's fall and preventing the sprue from accumulating on the fixing block 210, reducing the frequency of manual cleaning, and improving the ease of use of the sprue cutting device.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
