Description

TECHNICAL FIELD

[0001] The utility model relates to the field technology of ultrasonic water gap, especially to an ultrasonic water gap removing machine and injection molding and water gap integrated equipment. BACKGROUND

[0002] When injection molding small particle products, usually one mold has multiple cavities, a vertical gate is arranged at the center, and a longitudinal and horizontal branch runner is connected to the inner end of the vertical gate. A plurality of small particle products are arranged on the longitudinal and horizontal branch runner. For this kind of injection molding semi-finished product, the small particle products were previously detached by manual operation, which was low in operation efficiency and high in labor cost. Moreover, the periphery of the detached small particle products had a small amount of burrs, which needed to be removed manually, and the operation was troublesome.

[0003] For this kind of injection molding, some in the industry use ultrasonic water gap equipment to effectively improve production efficiency and solve the above-mentioned problems existing in manual operation. For example, CN220841278U discloses an ultrasonic water gap jig suitable for plastic bead injection molding plate, which is fixedly installed on the ultrasonic water gap equipment and used for installing and positioning the injection molding plate. The ultrasonic water gap jig includes a base and a plate positioning seat fixed relative to the base. The plate positioning seat is provided with a positioning groove and a material falling port. The upper side of the base is provided with two side plates spaced from each other. The front and rear ends of the plate positioning seat are horizontally fixed between the two side plates. The left and right sides of the plate positioning seat are provided with a left guard plate and a right guard plate which are horizontally slidably arranged relative to the base. The base is further provided with a sliding driver for driving the two guard plates to reciprocate. The area of the base below the plate positioning seat is further provided with a first material falling collection port and a second material falling collection port. A turnover piece is further arranged between the plate positioning seat and the two material falling collection ports. The turnover piece can guide the falling material from the material falling port to flow to the first material falling collection port or the second material falling collection port by turning its own angle. The base is provided with a turnover driver for driving the turnover piece to turn. The plate positioning seat is provided with an air channel, and the positioning groove is provided with an air port communicating with the air channel. In the initial state, the turnover piece is in a posture opening to the first material falling collection port, the left guard plate and the right guard plate are in a mutually separated state, and the plate positioning seat is completely exposed. The injection molding plate is placed in the positioning groove, and then the sliding driver pushes the left guard plate and the right guard plate to be mutually clamped. The ultrasonic pressing block is pressed down and vibrated. The two side plates, the left guard plate and the right guard plate are wrapped around the four sides of the injection molding plate to form a splash-proof enclosure. Then the plastic bead material will flow to the first material falling collection port under the guidance of the turnover piece. After the plastic bead removal is completed, the turnover driver drives the turnover piece to turn. After the waste is crushed, the ultrasonic pressing block rises by a distance but is not completely out of the surrounding range of the left guard plate and the right guard plate. Then air is supplied into the air channel. The air flow blown out by the air port can blow the waste fragments away from the positioning groove and along the turnover piece to the second material falling collection port.

[0004] However, the tool structure is complex, and the structure and shape of the positioning seat need to match the plastic bead injection molded plate, that is, a different plastic bead injection molded plate needs to replace the positioning seat or even the entire tool, resulting in poor universality, and the crushing of waste materials is integrated in the tool, limiting the improvement of overall efficiency.

[0044] The design emphasis of the utility model lies in that the lower end of the jig 2 in a cylindrical shape is installed on the ultrasonic vibration head, the central positioning groove 6 and the radial positioning groove 7 are concavely arranged downward at the top of the jig 2, the water gate convex part at the inner end of the vertically extending gate of the injection molded part semi-finished product is vertically positioned in the central positioning groove 6 to form positioning, and the strip-shaped water gate of the longitudinal branch flow channel in the longitudinal and transverse branch flow channel is horizontally positioned in the radial positioning groove 7, so that the ultrasonic vibration source generates ultrasonic vibration and uniformly conducts to the water gate through the jig 2, so that the small particle products are self-high-frequency vibrated and then vibrated and fall from the water gate into the water gate cutting work cavity 4, the jig 2 has simple structure and is suitable for various plate-like injection molded products with vertically extending gates, longitudinal and transverse branch flow channels and small particle products, and has good universality.

[0045] And, the breaking of the water gap is not dependent on a jig, but the water gap is moved into the pulverizer 400 for pulverization, effectively improving the overall efficiency of the water gap removal. At the same time, the automatic transfer machine 200, the ultrasonic water gap removal machine 300 and the pulverizer 400 are attached to the injection molding machine 100, and the automatic transfer machine 200 is connected between the injection molding machine 100, the ultrasonic water gap removal machine 300 and the pulverizer 400, which saves the turnover and storage of the plate-like injection molded products after demolding, and further improves the production efficiency.

[0046] The above is only a preferred embodiment of the present application, and does not limit the technical scope of the present application in any way. Therefore, any slight modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
