Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, and specifically relates to a full-automatic rubber-coated injection molding machine. Background Technique

[0002] Injection molding is a method for producing industrial product shapes. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding, compression molding, and die-casting methods. Injection molding is usually completed by an injection molding machine. The injection molding machine is the main molding equipment that uses thermoplastic or thermosetting materials to make various shaped plastic products using plastic molding molds. Injection molding is achieved through an injection molding machine and a mold.

[0003] After investigation, the Chinese patent discloses a full-automatic rubber-coated injection molding machine (Publication No.: CN 219360126 U). The utility model discloses a full-automatic rubber-coated injection molding machine, which relates to the technical field of injection molding machine equipment.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] The present utility model provides a full-automatic rubber coating injection molding machine, which includes a storage barrel 1. A discharge pipe is fixedly installed on one side of the storage barrel 1. One end of the discharge pipe is fixedly installed with an extrusion pipe 2. A rotary replacement assembly 3 is arranged on the lower surface of the storage barrel 1. The rotary replacement assembly 3 includes a first motor 301 fixedly installed on the lower surface of the storage barrel 1. The output end of the first motor 301 is fixedly installed with an output shaft. One end of the output shaft is fixedly installed with a rotary ring 302. A plurality of support rods 303 are fixedly installed on the outer surface of the rotary ring 302 in an annular array. One end of the support rod 303 is fixedly installed with a clamping ring 304. Arc-shaped clamping grooves are formed inside the support rod 303 and the clamping ring 304. An installation block 305 is slidably connected inside the arc-shaped clamping groove. A spray head 13 is installed inside the clamping ring 304. A groove is formed on the side surface of the spray head 13. The installation block 305 is adapted to the groove. Sealing rings 306 are slidably connected to the outer surfaces of the extrusion pipe 2 and the spray head 13. One side surface of the sealing ring 306 is fixedly installed with a side plate. An electric push rod 307 is fixedly installed on the upper surface of the side plate. The electric push rod 307 is fixedly installed on the lower surface of the storage barrel 1.

[0031] During long-term use, when the spray head 13 is blocked due to the accumulation of impurities, the staff replaces the spray head 13. First, start the electric push rod 307 to drive the sealing ring 306 to disengage from the surface of the spray head 13, and then start the first motor 301 through the control panel 11 to drive the rotary ring 302 at the bottom of the output shaft to rotate by 90 degrees. The rotary ring 302 drives the clamping ring 304 to move through the support rod 303 on one side. The clamping ring 304 drives the spray head 13 inside through the installation block 305, so that the blocked spray head 13 is separated from the lower surface of the extrusion pipe 2 and the new spray head 13 is moved to the lower surface of the extrusion pipe 2. Then start the electric push rod 307 to drive the sealing ring 306 to slide downward, so that the sealing ring 306 slides to the connection position between the spray head 13 and the extrusion pipe 2, improving the sealing performance after connection. The installation block 305 is inserted into the groove on the surface of the spray head 13 to disassemble and assemble the spray head 13.

[0032] For disassembling and assembling the spray head 13, such as Figure 2 And Figure 5As shown in the figure, a connecting column 4 is fixedly installed on one side surface of the installation block 305. One end of the connecting column 4 is fixedly installed with a sliding block. A first sliding groove is formed on the lower surface of the support rod 303. The sliding block is slidably connected to the inside of the first sliding groove. A return spring 12 is fixedly installed on the side surface of the sliding block. The lower surface of the sliding block is rotatably connected to a connecting rod 5 through a movable seat. One end of the connecting rod 5 is rotatably connected to a sliding ring 6 through a movable seat. The outer surface of the sliding ring 6 is slidably connected to a column 7. Handles are fixedly installed on both sides of the lower surface of the sliding ring 6. The top of the column 7 is rotatably connected to a rotating ring 302.

[0033] When the staff needs to disassemble the nozzle 13, the sliding ring 6 is driven by the handle to slide on the outer surface of the column 7. The sliding ring 6 drives the sliding block to slide inside the first sliding groove through the connecting rod 5 and compress the internal return spring 12. The sliding block drives the connecting column 4 to move. The connecting column 4 drives the installation block 305 at one end to slide inside the arc-shaped card slot, so that the installation block 305 is disengaged from the inside of the groove, and thus the nozzle 13 can be disassembled. When the nozzle 13 needs to be installed, the reverse operation is performed.

[0034] A heating layer is provided on the outer surface of the extrusion tube 2. A spiral conveying blade 8 is rotatably connected to the inside of the extrusion tube 2. A driven column is fixedly installed at the top of the spiral conveying blade 8. Stabilizing members are rotatably connected to both sides of the outer surface of the driven column. The stabilizing members are fixedly installed on the side surface of the storage barrel 1.

[0035] The raw materials inside the extrusion tube 2 are heated through the heating layer. The driven column rotates inside the stabilizing member, and the driven column drives the spiral conveying blade 8 to rotate, so as to transport the raw materials from top to bottom.

[0036] A servo motor is fixedly installed on the upper surface of the storage barrel 1 through a bracket. The output end of the servo motor is fixedly installed with a driving shaft. A stirring shaft is fixedly installed at the bottom of the driving shaft. Stirring blades 9 are provided on the outer surface of the stirring shaft. Pulley 10 is provided on the outer surfaces of both the driving shaft and the driven column. A belt is lapped on the outer surface of the pulley 10.

[0037] The servo motor is started to drive the driving shaft to rotate. The driving shaft drives the stirring shaft and the stirring blades 9 to rotate, and the raw materials inside are stirred, reducing the caking of the raw materials. During the rotation of the driving shaft, the driven column on the other side rotates synchronously through the transmission of the pulley 10, so that the spiral conveying blade 8 at the bottom of the driven column rotates synchronously, reducing another power source for driving the driven column and reducing the cost during the use of the equipment.

[0038] The storage barrel 1 is fixedly installed on a bottom plate through a support frame. A control panel 11 is provided on the upper surface of the bottom plate. A lifting platform is provided on the upper surface of the bottom plate.

[0039] Drive each component to run through the control panel 11, place the workpiece on the surface of the lifting table, and perform rubber coating and injection molding operations on the workpiece by lifting the lifting table.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
