Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a highly reliable water-cutting device. Background Technology

[0002] In the injection molding process, molten plastic enters the mold cavity through the gating system, and the molded product is connected to the plastic residue in the gating system (i.e., the sprue). To obtain a complete and independent product, the sprue must be removed. With the automation and large-scale development of injection molding production, manual sprue removal can no longer meet the needs of efficient and precise production, and sprue removal devices have emerged. For example, patent number CN202221918125.9 discloses a PIN feeding and sprue removal device for injection molded products; it includes a PIN feeding device and a sprue removal device for removing the sprue of the injection molded product; the PIN feeding device includes a linear feeder and a material handling robot located above the linear feeder; during operation, the material handling robot picks up the material, and the linear feeder delivers the material horizontally to the sprue removal device for sprue removal.

[0003] This type of sprue-cutting device has automated the sprue-cutting process, which is beneficial for factories to improve product production efficiency. However, in actual use, the feeding device of this sprue-cutting device only has a degree of freedom in the horizontal direction. During the sprue-cutting process, plastic fragments generated by cutting are easily embedded in the gaps of the parts, causing the equipment to malfunction, the automation process to be interrupted, and the product production efficiency to be reduced. Therefore, a sprue-cutting device that can solve the above problems is proposed. Utility Model Content

Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] A preferred embodiment of this utility model provides a highly reliable water-cutting device, such as... Figures 1-7 As shown, the device includes a mounting base 1, a movable plate 2 that slides laterally on the mounting base 1, a cutting assembly 3 for cutting the sprue, and a clamping assembly 4 that clamps the material and transfers it to the cutting end of the cutting assembly 3.

The clamping assembly 4 includes a movable rod 40 that slides longitudinally in the mounting hole, and a material clamping member 41 located at the lower end of the movable rod 40. The material clamping member 41 is preferably a finger cylinder.

[0034] During operation, the material clamping component 41 clamps the material to complete the material picking. Then, the movable plate 2 slides laterally on the mounting base 1, sliding above the cutting component 3. Subsequently, the movable rod 40 slides downward longitudinally, and the material clamping component 41 places the sprue on the cutting end of the cutting component 3 to complete the cutting. Then, the movable rod 40 slides upward, leaving the cutting end of the cutting component 3 and sliding back to the initial position when picking up the material along the mounting base 1 to perform the next round of material picking. The sprue cutting device provided by this utility model automates the sprue cutting process by repeating the above working steps.

[0035] In this embodiment, the movable plate 2 is provided with a longitudinally penetrating avoidance hole 22 for the avoidance movable rod 40, and the side wall of the avoidance hole 22 is provided with a first transmission component 24 for driving the mounting plate 20 to move. This arrangement gives the movable rod 40 a degree of freedom of movement in the horizontal direction, and the position of the material clamping component 41 can be adjusted according to the sprue position of different injection molded parts, so as to facilitate better fit between the sprue and the cutting end, and increase the application range of this sprue cutting device.

[0036] In this embodiment, the first transmission component includes a first worm gear 240 and a first worm 241 adapted to the first worm gear 240. The first worm 241 is disposed on one side wall of the clearance hole 22. The gear of the first worm 241 is disposed facing the movable rod 40. A first driving member 242 for driving the first worm gear 240 to rotate is provided on the upper surface of the mounting plate 20. The movable end of the driving member passes through the mounting plate 20 and is fixedly connected to the first worm gear 240.

[0037] In this embodiment, the clearance hole 22 is elongated and can accommodate multiple clamping components 4. This allows two clamping components 4 to be used together to hold a larger material, or multiple clamping components 4 to hold multiple smaller materials, thereby increasing cutting efficiency. This further expands the applicability of the device and makes it more practical.

[0038] In this embodiment, a limiting part 25 is provided vertically upward at the end of the movable plate 2 away from the mounting base 1. An elastic member 26 is provided on the side wall of the limiting part 25 facing the mounting plate 20 to limit the mounting plate 20. Preferably, there are three elastic members 26 to improve the safety of the mounting plate 20 during horizontal sliding.

[0039] In this embodiment, the highly reliable water-cutting device further includes a second worm gear 42 and a second worm 43 adapted to the second worm gear 42; the second worm 43 is vertically disposed on one side wall of the movable rod 40; a fixing plate 27 is vertically disposed on the edge of the mounting hole, and a second driving member 44 for driving the second worm gear 42 is disposed on the side wall of the fixing plate 27 away from the movable rod 40, and the movable end of the second driving member 44 passes through the fixing plate 27 and is fixedly connected to the worm gear.

[0040] In this embodiment, the lower end of the fixed plate 27 is provided with a protrusion 270 extending out of the mounting plate 20 in the horizontal direction, and a guide rail 28 protruding on one side wall of the movable plate 2 to guide the mounting plate 20. The lower end of the protrusion 270 is provided with a guide portion 271 that is slidably connected to the guide rail 28; thereby enhancing the stability of the mounting plate 20 during the sliding process.

[0041] In this embodiment, the cutting assembly 3 includes a protective box 30 with an open upper end and a fixed base 31 at the bottom of the protective box 30. An ultrasonic vibration module 32 is provided on the bottom surface inside the protective box 30. The ultrasonic vibration module 32 cuts the sprue mainly by using the energy generated by the high-frequency vibration of ultrasonic waves. When the clamping assembly 4 clamps the material and descends until the sprue is against the cutting end of the ultrasonic module, the ultrasonic generator generates a high-frequency electrical signal, which drives the transducer to convert electrical energy into mechanical vibration. This causes friction between plastic molecules at the sprue to generate high temperature, and at the same time, shear force is formed on the cutting surface, causing the sprue to separate from the product. This cutting method has a simple structure, is convenient and quick to cut, and has good practicality.

[0042] In this embodiment, the protective box 30 includes a box body 300 and an outlet section 301 for discharging the cut material from the protective box 30; the outlet section 301 is located at the lower end of the box body 300; in use, a collection box can be placed at the lower end of the outlet section 301 to facilitate the collection of the required material.

[0043] In this embodiment, the upper surface of the mounting base 1 is provided with a mounting groove 10, and a third worm gear 11 is provided on one side wall of the mounting groove 10; a fixing part 29 is horizontally provided on one side wall of the movable plate 2, the fixing part 29 is located above the mounting groove 10, the lower end of the fixing part 29 is provided with a third worm wheel adapted to the third worm gear 11, and a third driving member 13 for driving the third worm wheel is fixedly provided above the fixing part 29, the movable end of the third driving member 13 passes through the fixing plate 27 and is fixedly connected to the third worm wheel; the arrangement of the first worm wheel 240 and the first worm 241, the second worm wheel 42 and the second worm 43, and the third worm wheel and the third worm gear 11 takes into account both high transmission efficiency and the compactness of the overall structure of the device, and has strong practicality; wherein, the first driving member 242, the second driving member 44 and the third driving member 13 are all rotary motors.

[0044] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
