Description

Technical Field

[0001] The utility model relates to the technical field of nozzle removal after injection molding, in particular to an ultrasonic nozzle waste removal and auxiliary recovery device. Background Art

[0002] After the plastic product is injection molded, corresponding connecting materials will be formed at the inlet and outlet of the molten hot liquid material. This connecting material is redundant sprue material, so it is also called sprue or gate. Only after the sprue is removed can each injection molded product be put into use.

[0003] Existing methods for removing the sprue produced by injection molding products are generally divided into the following types: one is manual cutting or tailoring, and the other is to use ultrasonic waves to act on the connection between the product and the sprue to remove the sprue.

[0004] Manual cutting or trimming will leave some residue at the connection between the nozzle and the product, requiring further polishing and grinding using the appropriate equipment. This increases the workload of the staff and also increases the number of operating procedures. Therefore, the use of ultrasonic nozzles offers a significant advantage. In ultrasonic nozzles, the output end of the ultrasonic equipment presses the connection between the nozzle and the product and provides high-frequency vibration. When the nozzle with a small cross-section is activated by ultrasonic energy, the friction between the plastic molecules is activated due to the high temperature, which increases stress and causes the flow channel at the injection molded product and the nozzle to break. The surface of the nozzle workpiece after cutting is flat and smooth, without whitening, and as beautiful as direct injection molding, saving a lot of labor and improving production efficiency.

[0005] However, after the existing ultrasonic de-sprue equipment removes the sprue, on the one hand, it is necessary to manually take out the product, and on the other hand, the sprue separated from the product will be directly scattered on the processing platform. Due to the small size of the sprue, it is not convenient to clean it. Moreover, the sprue does not belong to the defective material and can be recycled for secondary use. At the same time, the directly scattered sprue is not convenient to collect and recycle. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the existing technology, the purpose of the present invention is to provide an ultrasonic dewatering waste and auxiliary recovery device, which effectively solves the problem that the existing ultrasonic dewatering equipment is not convenient for collecting and recycling dewatering waste.

[0010] Preferably, the product carrying structure further comprises a product fixing portion, the product fixing portion comprises a fixed base plate and a fixed bayonet, and the fixed bayonet is provided on the fixed base plate for limiting the end of the product away from the water outlet.

[0011] Preferably, the product supporting structure also includes a sprue end positioning portion, which includes an end positioning groove and an ultrasonic impact clearance groove. The end positioning groove is used to accommodate one end of the product with a sprue and position the sprue, and the ultrasonic impact clearance groove is used to accommodate the sprue after ultrasonic impact.

DETAILED DESCRIPTION

[0030] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Refer to the instruction manual Figure 1-8 An ultrasonic waste removal and auxiliary recovery device includes a base 1, on which an ultrasonic device 2 is installed. The ultrasonic device 2 impacts the nozzle connection between two adjacent products, causing the nozzle to fall off the product. The use of the ultrasonic device 2 can make the connection between the nozzle and the product smoother and smoother, without the need for staff to trim the product a second time. After the product nozzle is removed, a product grabbing structure is also provided on the base 1 to grab the product and move it to the storage area for storage.

[0032] The ultrasonic device 2 includes an ultrasonic generator, a transducer, an output end, and a lifting structure. The lifting structure is used to move the ultrasonic output end closer to or farther away from the product.

[0033] The base 1 is provided with a product carrying structure 23, and the product carrying structure 23 is multiple. At the same time, the product carrying structure 23 is slidably connected to the base 1. Through the sliding connection between the product carrying structure 23 and the base 1, the lateral movement of the product carrying structure 23 is achieved, and the product can be moved directly under the ultrasonic equipment 2;

[0034] The product and the part with the nozzle are placed on the product supporting structure 23, and the output end of the ultrasonic device 2 can move up and down and approach or move away from the connection between the product and the nozzle.

[0035] The output end of the ultrasonic device 2 can be detachably connected to the body of the ultrasonic device 2. By replacing the output end of the ultrasonic device 2, it can be adapted to various products and nozzle shapes of various sizes.

[0036] A sprue pushing mechanism 24 is also provided on the base 1. The sprue pushing mechanism 24 has a pushing part. After the ultrasonic equipment 2 disconnects the sprue between adjacent products and the products, the pushing part pushes the sprue in an independent state. At the same time, a recovery port 3 is also provided on the base 1. The sprue pushed by the pushing part falls into the base 1 through the recovery port 3. The sprue falling into the recovery port 3 is melted by subsequent equipment for recycling and secondary use.

[0037] The ejection part includes a first drive component 4 and an ejection component. The first drive component 4 drives the ejection component to move the water outlet to the recovery port 3. The first drive component 4 can adopt a cylinder, an electric push rod or a motor. Generally, a cylinder is adopted. The output shaft of the cylinder is connected to the ejection component, and the movement of the ejection component is controlled by air pressure. The first drive component 4 can also adopt a servo motor. The circular motion of the motor is converted into the linear motion of the ejection component by a structure similar to a gear and rack or a belt and a pulley arranged between the servo motor and the ejection component.

[0038] The ejection assembly includes an ejection block 5 corresponding one to the water outlet, and a connecting plate 6 for synchronously controlling and connecting multiple ejection blocks 5. The output end of the first drive assembly 4 is fixedly connected to the connecting plate 6. The first drive assembly 4 drives the connecting plate 6 and the ejection block 5 thereon to push the water outlet disconnected from the product, so that the water outlet can move toward the recovery port 3.

[0039] The product carrying structure 23 further includes a product fixing base plate 7 and a fixing bayonet 8 . The product is placed in the fixing bayonet 8 , and the outer edge surface of the product is limited and fixed by the fixing bayonet 8 .

[0040] The product bearing structure 23 also includes an end positioning groove 9 and an ultrasonic impact yield groove 10. One end of the product with a water outlet is placed in the end positioning groove 9. The water outlet is limited and positioned by the end positioning groove 9. The ultrasonic impact yield groove 10 corresponds to the position of the water outlet. After the ultrasonic equipment 2 impacts the connection between the water outlet and the product, the ultrasonic impact yield groove 10 supports the water outlet in an independent state, so that the ejection block 5 can better push out and move the water outlet.

[0041] Multiple product carrying structures 23 are mounted on an auxiliary plate 17. The base 1 is connected to the auxiliary plate 17 via a guide rail 15, so that the auxiliary plate 17 can drive the product carrying structures 23 to slide relative to the base 1. At the same time, a third drive component 16 is also provided on the base 1. The output end of the third drive component 16 is fixedly connected to the auxiliary plate 17, and the auxiliary plate 17 drives the product carrying structures 23 to move on the base 1.

[0042] The third drive component 16 can adopt a structure such as a screw and a nut, a gear and a rack, or an electric push rod, among which a screw and a nut are generally used. The connection relationship between the screw and the nut can more stably move the product supporting structure 23 and the product thereon, so that the product supporting structure 23 can drive the product to move to the bottom of the ultrasonic equipment 2. At the same time, after the water outlet is removed, the product supporting structure 23 can drive the product to move out from under the ultrasonic equipment 2, which is convenient for subsequent grasping by the robot.

[0043] The auxiliary plate 17 is provided with a through hole 18 for use with the recovery port 3, and the water outlet falls into the recovery port 3 through the through hole 18. At the same time, the base 1 is also provided with a recovery enclosure 19 located between the auxiliary plate 17 and the base 1. The inner side wall of the recovery enclosure 19 is a trumpet shape that shrinks toward the recovery port 3. This shape is designed to allow the water outlet to better collect and fall.

[0044] The product grabbing structure is arranged on one side of the product carrying structure 23. The product carrying structure 23 includes a fixed plate 11 that can be moved up and down. The second driving component 14 is fixedly connected to the fixed plate 11. At the same time, the fixed plate 11 is also slidably connected with a left claw 12 and a right claw 13 that are relatively set. The second driving component 14 drives the left claw 12 and the right claw 13 to move relative to each other to achieve the grabbing of the product.

[0045] The up and down movement of the fixed plate 11 relies on a lifting cylinder fixedly connected to the base 1. The output end of the lifting cylinder is fixedly connected to the fixed plate 11. The lifting cylinder realizes the up and down movement of the fixed plate 11, and also realizes the positioning of the product between the left claw 12 and the right claw 13.

[0046] The second drive component 14 adopts a clamping cylinder, which controls the opposite movement of the left claw 12 and the right claw 13 through the two opposing clamping jaws of the clamping cylinder. At the same time, multiple left claws 12 and right claws 13 can be used. The multiple left claws 12 are connected through the first clamping plate 21, and the multiple right claws 13 are connected through the second clamping plate 22. The clamping jaws of the clamping cylinder are connected to the first clamping plate 21 or the second clamping plate 22 to achieve synchronous control of multiple left claws 12 and right claws 13.

[0047] The base 1 is further provided with a product receiving opening 20 , through which the products clamped by the left claw 12 and the right claw 13 flow into the next receiving space to receive and organize the products after the water outlet is removed.

[0048] When the present invention is in use, the product after injection molding is transferred from the injection molding machine to the product carrying structure 23 via the transfer device, wherein the end with the nozzle is located in the end positioning groove 9, and the nozzle is located in the ultrasonic impact yielding groove 10. After the product is placed, the third drive component 16 drives the auxiliary plate 17 to drive the product carrying structure 23 thereon to move toward the ultrasonic device 2, so that the product carrying structure 23 is located directly below the ultrasonic device 2;

[0049] The ultrasonic device 2 relies on its own lifting ability to move downward and approach the connection between the nozzle and the product. The connection between the product and the nozzle is disconnected by the appropriate end of the ultrasonic device 2. After the connection between the nozzle and the product is disconnected, the end of the ultrasonic device 2 moves upward to a suitable height. At the same time, the first driving component 4 drives the connecting plate 6 and the pushing block thereon to push the nozzle to the recovery port 3.

[0050] Under the action of the third drive component 16, the products on the multiple product carrying structures 23 are dewatered. After the dewatering is completed, the third drive component 16 drives the multiple product carrying structures 23 to move toward the product grabbing structure. Under the action of the product grabbing structure, the left claw 12 and the right claw 13 are used to grab the products and move them to above the product storage port 20. The products flow through the product storage port 20 to the storage structure for corresponding storage and placement.

[0051] The utility model adopts multiple ejection blocks 5 in the ejection part and the recovery port 3 to push the water outlet removed by the product, so as to prevent the water outlet removed by the product from being scattered on the base 1 and being inconvenient to collect. The utility model also adopts a recovery enclosure 19 arranged at the recovery port 3. At the same time, the inner side wall of the recovery enclosure 19 is in a trumpet shape that shrinks toward the recovery port 3, which can further assist in collecting the removed water outlet.

[0052] The utility model adopts a product grabbing structure arranged on the base 1 to automatically grab the products after the water outlet, and moves the products after the water outlet to the next structure for storage through the product storage opening 20 opened on the base 1, thereby reducing the cost of manual retrieval and improving the production efficiency of the product.
