Description

Technical Field

[0001] This utility model relates to the field of adhesive applicator technology, and in particular to a fast adhesive applicator for coated sand shells. Background Technology

[0002] In existing technologies, special molding adhesive is usually applied to the shell-mold mating area before the coated sand is closed to prevent the casting from escaping. When using molding adhesive for bonding, it is usually applied by manually squeezing the glue bottle or manually operating the glue gun. The glue application speed is very slow, it is not easy to control the amount of glue dispensed, it increases manual intervention, and reduces glue application efficiency.

[0003] Therefore, it is essential to provide a fast-dispensing adhesive applicator for coated sand shell molding to address the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a fast glue dispensing machine for coated sand shell molding. A lifting cylinder, powered on, raises and lowers the connecting beam, while simultaneously pressing down the fast extrusion mechanism mounted on the beam. The fast extrusion mechanism, with its reducer and electric push rod, extrudes the glue from the lower glue tank and discharges it through the glue dispensing pipe. A system control box allows control of the electric push rod, thereby controlling the glue dispensing volume, reducing manual operation while improving dispensing efficiency.

[0005] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] The rapid extrusion mechanism includes a mounting box, which is fixed in the center of the connecting crossbeam. A drive motor is installed inside the mounting box, and a reducer is installed on the drive motor. An electric push rod is installed at the bottom of the reducer.

[0008] The glue bucket is fitted with a sealing cap, through which a glue outlet tube is installed. An elastic sealing ring is installed between the sealing cap and the glue bucket, and an exhaust valve is provided at the top of the sealing cap.

[0009] Specifically, the glue bucket is installed directly below the rapid extrusion mechanism, and the motor frequency converter is installed inside the support base at the bottom of the glue bucket. The motor frequency converter is connected to the lifting cylinder.

[0010] Specifically, a system control box is installed on the outside of the cabinet, and a power supply unit is installed on the system control box.

[0039] The present invention will be further described in conjunction with the following embodiments.

[0040] Example 1.

[0041] like Figure 1-4 As shown, a fast-dispensing coated sand shell molding glue applicator includes a cabinet 1. Two sets of lifting cylinders 2 are installed at the bottom of the cabinet 1. A connecting beam 3 is installed at the top of the lifting cylinders 2. A fast extrusion mechanism 4 is installed in the center of the connecting beam 3. A glue tank 5 is arranged between the two sets of lifting cylinders 2. A support base 6 is arranged between the glue tank 5 and the cabinet 1.

[0042] When the lifting cylinder 2 is raised and lowered by external connection control, it can drive the connecting beam 3 on the lifting cylinder 2. At the same time, it can control the rapid extrusion mechanism 4 on the connecting beam 3 to rise and fall. With the cooperation of the rapid extrusion mechanism 4 and the glue tank 5 below, the molding glue inside the glue tank 5 can be squeezed and extracted, which facilitates the application of molding glue and improves the application efficiency of molding glue.

[0043] The rapid extrusion mechanism 4 includes a mounting box 7, which is fixed in the center of the connecting beam 3. A drive motor 8 is installed inside the mounting box 7. A reducer 9 is installed on the drive motor 8. An electric push rod 10 is installed at the bottom of the reducer 9. A glue dispensing pipe 11 is connected to the electric push rod 10 and extends into the glue tank 5.

[0044] The drive motor 8 installed in the mounting box 7 can be set in the center of the connecting beam 3 through the mounting box 7. The drive motor 8 provides power to the reducer 9. The reducer 9 drives the electric push rod 10 to push downward slowly. The electric push rod 10 and the glue dispensing pipe 11 installed at the bottom of the reducer 9 cooperate with the glue tank 5 to extrude the compound glue in the glue tank 5. The extrusion operation is carried out through the glue dispensing pipe 11.

[0045] A sealing top cover 12 is installed at the top of the glue bucket 5. An elastic sealing ring 13 is installed between the sealing top cover 12 and the glue bucket 5. An exhaust valve 14 is provided at the top of the sealing top cover 12. The sealing top cover 12 at the top of the glue bucket 5 can seal the glue bucket 5. At the same time, the elastic sealing ring 13 provided on the sealing top cover 12 can increase the airtightness. The gas inside the glue bucket 5 can be released through the exhaust valve 14 on the sealing top cover 12, which ensures the glue dispensing efficiency and facilitates the glue dispensing from the glue dispensing pipe 11.

[0046] The glue bucket 5 is installed directly below the rapid extrusion mechanism 4. The support base 6 installed at the bottom of the glue bucket 5 has a motor frequency converter 15 installed inside. The motor frequency converter 15 is connected to the lifting cylinder 2. The motor frequency converter 15 installed inside the support base 6 can cooperate with the lifting cylinder 2 to control the movement of the lifting cylinder 2.

[0047] The cabinet 1 is equipped with a system control box 16 on the outside. The system control box 16 is equipped with a power supply unit 17. The system control box 16 can be controlled by external signals to control the circular table of drive motor 8 and reducer 9, and control the amount of glue dispensed.

[0048] One end of the dispensing tube 11 extends into the glue tank 5. The bent nozzle 18 installed on the dispensing tube 11 can adjust the dispensing position, making it convenient to apply the extruded glue.

[0049] Anti-collision pads 19 are installed on the sealing top cover 12. The anti-collision pads 19 are installed between the electric push rod and the sealing top cover 12 to prevent the electric push rod 10 from directly contacting the sealing top cover 12 and causing collisions, thereby preventing the sealing top cover 12 from deforming and providing a buffering effect.

[0050] During the production process, the connecting beam 3 is raised and lowered by the lifting cylinder after being powered on, and the rapid extrusion mechanism 4 installed on the connecting beam 3 is pressed down. The reducer 9 and electric push rod 10 in the rapid extrusion mechanism 4 work together to extrude the glue in the glue bucket 5 below and discharge it from the glue outlet pipe 11. The system control box 16 can control the electric push rod 10, thereby controlling the glue output, reducing manual operation and improving glue output efficiency.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
