Description

Technical Field

[0001] This utility model relates to the field of sprue cutting technology for plastic parts, specifically, to a sprue cutting device for automotive plastic parts. Background Technology

[0002] A sprue is a guide post left in the mold blank during injection molding, serving as the part between the product and the runner. The gate and runner together are called a sprue. The excess material at the junction of the sprue and the mold (also called flash) is inevitably produced during injection molding and must be removed later. A sprue cutting device is a device used to cut sprues and flash. Automotive plastic part sprue cutting devices use ultrasonic cutting principles. The core is to use ultrasonic vibration energy to achieve efficient and precise cutting of the sprue in plastic parts. The specific process is as follows: The ultrasonic generator in the device converts mains electricity (electrical energy) into a high-frequency electrical signal (usually 20kHz-40kHz), which is transmitted to the ultrasonic transducer. The transducer converts the high-frequency electrical signal into high-frequency mechanical vibration (longitudinal vibration of the same frequency), and amplifies the vibration amplitude through an amplitude transformer (usually amplified to tens of micrometers), finally transmitting it to the cutting tool (cutter). High-frequency vibration cutting: When a high-speed vibrating cutter contacts the sprue of a plastic part, the high-frequency (tens of thousands of times per second) mechanical impact causes intense internal molecular motion in the material at the connection between the sprue and the plastic part, resulting in instantaneous softening or breakage. This vibration cutting method differs from the "compression fracture" of traditional mechanical cutting; instead, it utilizes vibration energy to disrupt the internal bonding forces of the material, achieving "separation cutting."

[0003] Existing automotive plastic part sprue cutting devices often leave the cut plastic parts scattered on the worktable after vibration cutting, making subsequent cleaning inconvenient. Furthermore, the process of manually holding the plastic parts close to the ultrasonic vibrating head and then lowering it to cut the sprue poses a certain degree of danger. Therefore, a new automotive plastic part sprue cutting device is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a sprue cutting device for automotive plastic parts, which solves the problem that in the prior art, after the sprue cutting device vibrates and cuts the sprue of the plastic parts, the cut plastic parts are scattered randomly on the table, which is inconvenient for subsequent cleaning. At the same time, the plastic parts are usually manually held close to the ultrasonic vibrating head and then the vibrating head is dropped to cut the sprue of the plastic parts, which is a certain degree of danger.

[0005] This utility model provides the following technical solution: a sprue cutting device for automotive plastic parts, including a base, a side frame fixedly connected to the top of the base, an ultrasonic vibration cutter provided at the top of the side frame, an installation groove opened at the bottom of the base, a translation component provided inside the installation groove, a placement component provided between the side end of the translation component and the top of the base, and a pressing component for pressing the plastic part provided at the top of the placement component.

[0006] As a preferred embodiment of the above technical solution, the ultrasonic vibration cutting machine includes a cylinder, which is fixedly installed on the top of the side frame, and an ultrasonic cutting blade is installed on the telescopic end of the cylinder.

[0007] As a preferred embodiment of the above technical solution, the translation component includes a motor, which is fixedly mounted on the side of the base. A screw is installed at the output end of the motor. The side end of the screw is rotatably disposed inside the mounting groove. A guide rod is fixedly connected between the inner sides of the mounting groove. A threaded sleeve is threaded to the outer end of the screw, and the side end of the threaded sleeve is sleeved on the outer end of the guide rod.

[0008] As a preferred embodiment of the above technical solution, the placement assembly includes an extension plate, which is fixedly connected to the side end of the threaded sleeve and extends to the top of the base. Two wires are spaced apart at the top of the extension plate.

[0009] As a preferred embodiment of the above technical solution, the top of the base has two sliding grooves, and the bottom of the extension plate is fixedly connected to two sliders, each of which is slidably connected in each sliding groove.

[0010] As a preferred embodiment of the above technical solution, the pressing component includes an electric push rod, which is fixedly installed at the top of the extension plate. A connecting plate is installed at the telescopic end of the electric push rod, and a plurality of connecting rods are fixedly connected to the bottom end of the connecting plate. A pressing plate is fixedly connected between the bottom ends of the plurality of connecting rods.

[0011] As a preferred embodiment of the above technical solution, the top of the base is provided with a sloping bucket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention involves placing a plastic part on top of a placement component and securing it with a pressing component. Then, by activating a translation component, the placement component is moved horizontally, aligning the sprue of the plastic part with the ultrasonic vibrating cutter. The ultrasonic vibrating cutter then moves downwards to vibrate and cut the sprue. The plastic part falls into a sloping hopper and slides down into a collection frame outside the base, where it is automatically collected. This prevents the cut plastic part from scattering randomly on the work surface, making subsequent cleaning difficult. Furthermore, the pressing component secures the plastic part during the vibrating cut, eliminating the need for manual handling near the ultrasonic vibrating cutter head and reducing operational risks.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a sprue cutting device for automotive plastic parts, including a base 1, a sloping bucket 101 at the top of the base 1, a side frame 104 fixedly connected to the top of the base 1, an ultrasonic vibration cutter 2 at the top of the side frame 104, an installation groove 103 at the bottom of the base 1, a translation component 3 inside the installation groove 103, a placement component 4 between the side end of the translation component 3 and the top of the base 1, and a pressing component 5 at the top of the placement component 4 for pressing the plastic part. After the plastic part is placed on the top of the placement component 4, the pressing component 5 presses the plastic part against the plastic part. The plastic part is fixed in place. At this time, the translation component 3 is activated to move the placement component 4 so that the sprue position of the plastic part is aligned with the ultrasonic vibration cutter 2. The ultrasonic vibration cutter 2 then moves down to vibrate and cut the sprue position. The plastic part can fall into the sloping hopper 101 and slide down the sloping hopper 101 into the collection frame outside the base 1, where it is automatically collected. This avoids the cut plastic parts from being scattered on the table, which would be inconvenient for subsequent cleaning. At the same time, when the plastic part is vibrating to cut the sprue, it is fixed by the pressing component 5, eliminating the need for manual handling near the ultrasonic vibration cutter head and reducing the danger of the operation.

[0021] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the translation component 3 includes a motor 301, which is fixedly mounted on the side of the base 1. A screw 302 is mounted on the output end of the motor 301. The side end of the screw 302 is rotatably disposed inside the mounting groove 103. A guide rod 303 is fixedly connected between the inner sides of the mounting groove 103. A threaded sleeve 304 is threadedly connected to the outer end of the screw 302. The side end of the threaded sleeve 304 is sleeved on the outer end of the guide rod 303. The placement component 4 includes an extension plate 401, which is fixedly connected to the side end of the threaded sleeve 304. The extension plate 401 extends to the top of the base 1. Two wires 403 are spaced apart at the top of the extension plate 401. The top of the base 1 has... There are two slide grooves 102, and two sliders 402 are fixedly connected to the bottom end of the extension plate 401. Each slider 402 is slidably connected in each slide groove 102, which can provide stable support for the extension plate 401 at the top of the base 1. In practice, the screw 302 is rotated by starting the motor 301. Due to the limit of the guide rod 303 on the screw sleeve 304, the screw sleeve 304 can be translated to the outer end of the screw 302 and the guide rod 303. When the screw sleeve 304 drives the extension plate 401 to translate, it is convenient to make the wire 403 at one end located at the bottom end of the ultrasonic cutting blade 202. At this time, it is convenient to perform vibration cutting on the plastic parts placed at the top of the extension plate 401.

[0022] As one implementation method in this embodiment, such as Figure 1 and Figure 4As shown, the pressing assembly 5 includes an electric push rod 501, which is fixedly installed on the top of the extension plate 401. A connecting plate 502 is installed on the telescopic end of the electric push rod 501. Several connecting rods 503 are fixedly connected to the bottom end of the connecting plate 502. A pressing plate 504 is fixedly connected between the bottom ends of the several connecting rods 503. In practice, by starting the electric push rod 501, the connecting plate 502, connecting rods 503 and pressing plate 504 are driven to move downward. At this time, the pressing plate 504 presses against the top of the plastic part to fix the plastic part, thereby facilitating the subsequent ultrasonic cutting blade 202 to vibrate and cut the sprue position of the plastic part.

[0023] As one implementation method in this embodiment, such as Figure 1 As shown, the ultrasonic vibration cutting machine 2 includes a cylinder 201, which is fixedly installed on the top of the side frame 104. An ultrasonic cutting blade 202 is installed on the telescopic end of the cylinder 201. In practice, the cylinder 201 is started to drive the ultrasonic cutting blade 202 to move down. At this time, the ultrasonic cutting blade 202 can vibrate and cut the plastic part at the sprue position. The cut plastic part will fall into the sloping bucket 101 and slide down the sloping bucket 101 into the collection frame outside the base 1 and be automatically collected. This can prevent the cut plastic parts from being scattered on the table and making subsequent cleaning inconvenient.

[0024] Working principle: By placing the plastic part on the top of the extension plate 401, at this time according to... Figure 1 After placement as shown, the connecting plate 502, connecting rod 503, and pressure plate 504 are moved downwards by activating the electric push rod 501. At this time, the pressure plate 504 presses against the top of the plastic part to fix it, thus facilitating the subsequent vibration cutting of the sprue position of the plastic part by the ultrasonic cutting blade 202. Then, the screw 302 is rotated by activating the motor 301. Due to the limiting of the threaded sleeve 304 by the guide rod 303, the threaded sleeve 304 can move horizontally at the outer end of the screw 302 and the guide rod 303. At this time, when the threaded sleeve 304 drives the extension plate 401 to move horizontally, the wire 40 at one end is... 3 is located at the bottom of the ultrasonic cutting blade 202. At this time, the start cylinder 201 drives the ultrasonic cutting blade 202 to move down. The ultrasonic cutting blade 202 can then vibrate and cut the sprue of the plastic part. The cut plastic part will fall into the sloping hopper 101 and slide down the sloping hopper 101 into the collection frame outside the base 1, where it will be automatically collected. This avoids the cut plastic parts from being scattered on the table, which is inconvenient for subsequent cleaning. At the same time, when the plastic part is vibrating to cut the sprue, it is fixed by the pressure plate 504, eliminating the need for manual handling near the ultrasonic vibrating blade head and reducing the danger of the operation.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
