Description

Technical Field

[0001] This utility model relates to the field of plastic injection molding technology, and specifically to a plastic injection molding demolding device. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are typically produced using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. In plastic injection molding production, a demolding device is required to help with rapid demolding.

[0003] Most existing injection molding machines require manual demolding after injection molding, which is inefficient and cumbersome.

[0004] As disclosed in Chinese Patent CN214820353U, an injection molding machine for processing plastic buckets includes a mounting base, two sets of hydraulic cylinders, a mounting frame, a rotating plate, a brake stepper motor, four sets of support columns, a first mounting plate, a second mounting plate, an outer mold, two sets of inner molds, and an extruder. The two sets of hydraulic cylinders are fixedly mounted on the mounting base, and the output ends of the two sets of hydraulic cylinders are fixedly connected to the bottom end of the mounting frame. The rotating plate is rotatably mounted inside the mounting frame. The brake stepper motor is fixedly mounted on the front end of the mounting frame, and the output end of the brake stepper motor is connected to the rotating plate for transmission. The two sets of inner molds are respectively fixedly mounted on the top and bottom ends of the rotating plate. The four sets of support columns are all fixedly mounted on the mounting base. The first mounting plate is fixedly mounted on the upper middle part of the four sets of support columns, and the second mounting plate is fixedly mounted on the top of the four sets of support columns.

[0005] The above-mentioned device lacks a material ejection and demolding mechanism. If demolding is done manually, it will affect production efficiency. If demolding is done by lifting from the bottom up, the molded part may be difficult to pick up after being lifted, resulting in poor material ejection. Most injection molding devices still have demolding and material ejection problems after injection molding, which are not easy to solve.

[0006] Therefore, a plastic injection molding demolding device is proposed to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a plastic injection molding demolding device in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A plastic injection molding demolding device includes a fixed base, with support columns fixedly connected to the four corners of the bottom surface of the fixed base, support bases fixedly connected to the bottom surfaces of the support columns, a column fixedly connected to the upper surface of the fixed base, and a top plate fixedly installed on the upper surface of the column. A demolding component is provided on the upper surface of the fixed base, and a sliding groove is provided on one side of the upper surface of the fixed base.

[0010] Furthermore, the demolding assembly includes a docking module and a receiving module. The docking module includes a moving unit and a connecting unit. The moving unit includes an installation groove formed on the upper surface of the fixed base. A threaded column is rotatably installed on the inner wall of the installation groove. A drive motor is fixedly installed on one side of the outer surface of the fixed base, and the output end of the drive motor is connected to one end of the threaded column. A moving block engages on the outer surface of the threaded column.

[0011] Furthermore, the threaded post has two reverse threads, the moving blocks are symmetrically distributed on both sides of the outer surface of the threaded post, a circular hole is penetrating one side of the inner wall of the mounting groove, and one end of the threaded post passes through the circular hole and is connected to the output end of the drive motor.

[0012] Furthermore, the connecting unit includes a left mold seat fixedly installed on the upper surface of one side of the movable block, and a sealing groove is provided on one side of the outer surface of the left mold seat. A right mold seat is fixedly connected to the upper surface of the other side of the movable block, and a sealing strip is fixedly connected to one side of the outer surface of the right mold seat. The right mold seat and the left mold seat are snap-fitted together.

[0013] Furthermore, the material receiving module includes a fixed plate fixedly installed on one side of the outer surface of the fixed base. A cylinder is fixedly installed on one side of the outer surface of the fixed plate. The output end of the cylinder is connected to a telescopic column.

[0016] This invention, through the setting of a demolding component, allows the left and right mold seats on both sides to move under the drive of a moving block during injection molding. The two mold seats are connected and interlocked, and a sealing strip is installed at the connection point to prevent the injection molding material from overflowing. After injection molding is completed, the two mold seats separate and interlock, which allows the injection molded product to be demolded quickly. The injection molded product is then pushed to the chute for discharge by a material receiving module. When the injection molded product falls into the collection trough, it will squeeze the collection box. At the same time, multiple connecting springs set on the bottom surface of the collection box can buffer this impact, protecting the injection molded product and preventing it from being damaged.

[0027] like Figure 1-4 As shown, a plastic injection molding demolding device includes a fixed base 1, with support columns 2 fixedly connected to the four corners of the bottom surface of the fixed base 1, and support bases 201 fixedly connected to the bottom surface of the support columns 2. A column 3 is fixedly connected to the upper surface of the fixed base 1, and a top plate 301 is fixedly installed on the upper surface of the column 3. A demolding component 4 is provided on the upper surface of the fixed base 1, and a groove 414 is provided on one side of the upper surface of the fixed base 1. When demolding is required after injection molding, the demolding component 4 is operated to demold the injection-molded plastic product and push the plastic product to the groove 414 for discharge and collection.

[0028] The demolding assembly 4 includes a docking module and a receiving module. The docking module includes a moving unit and a connecting unit. The moving unit includes a mounting groove 401 opened on the upper surface of the fixed base 1. A threaded column 404 is rotatably mounted on the inner wall of the mounting groove 401. A drive motor 403 is fixedly mounted on one side of the outer surface of the fixed base 1, and the output end of the drive motor 403 is connected to one end of the threaded column 404. A moving block 405 is engaged on the outer surface of the threaded column 404. When the power of the drive motor 403 is turned on, the output end of the drive motor 403 drives the threaded column 404 to rotate, so that the moving blocks 405 engaged on both sides of the outer surface of the threaded column 404 move towards each other. The moving blocks 405 on both sides drive the left mold base 406 and the right mold base 407 to move towards each other, so that the left mold base 406 and the right mold base 407 close and dock.

[0029] The threaded column 404 has two reverse threads. The moving blocks 405 are symmetrically distributed on both sides of the outer surface of the threaded column 404. A circular hole 402 passes through one side of the inner wall of the mounting groove 401. One end of the threaded column 404 passes through the circular hole 402 and is connected to the output end of the drive motor 403. The two reverse threads allow the meshing moving blocks 405 to move towards each other or in opposite directions, which facilitates adjusting the positions of the left mold base 406 and the right mold base 407 for mold connection or demolding.

[0030] The connecting unit includes a left mold base 406 fixedly installed on the upper surface of a side movable block 405, and a sealing groove 409 is provided on one side of the outer surface of the left mold base 406. A right mold base 407 is fixedly connected to the upper surface of the other side movable block 405, and a sealing strip 408 is fixedly connected to one side of the outer surface of the right mold base 407. The right mold base 407 and the left mold base 406 are snap-fit ​​connected. When the left mold base 406 and the right mold base 407 are mated, the sealing strip 408 installed on one side of the outer surface of the right mold base 407 enters the sealing groove 409 opened on one side of the outer surface of the left mold base 406 to seal the connection between the left mold base 406 and the right mold base 407.

[0031] The receiving module includes a fixed plate 410 fixedly installed on one side of the outer surface of a fixed base 1. A cylinder 411 is fixedly installed on one side of the outer surface of the fixed plate 410. The output end of the cylinder 411 is connected to a telescopic column 412. A push seat 413 is fixedly installed on one end of the telescopic column 412, and the bottom surface of the push seat 413 is slidably connected to the upper surface of the fixed base 1. A connecting rod 415 is fixedly connected to one side of the bottom surface of the fixed base 1. A connecting platform 416 is fixedly connected to one end of the connecting rod 415. A connecting spring 417 is fixedly connected to the upper surface of the connecting platform 416. A receiving device is fixedly connected to the upper end of the connecting spring 417. The collection box 418 has a collection groove 419 on its upper surface. The first cylinder 411 is operated, and the output end of the first cylinder 411 pushes the first telescopic column 412 to move. The first telescopic column 412 then drives the push seat 413 to move, pushing the injection molded part on the upper surface of the fixed seat 1 to the slide groove 414. The injection molded part slides from the slide groove 414 into the collection groove 419. When the injection molded part falls into the collection groove 419, it presses the collection box 418 downward and the connecting spring 417. The connecting spring 417 is compressed and generates a restoring elastic force to push the collection box 418 upward, thereby protecting the injection molded part from falling.

[0032] A second cylinder 5 is fixedly installed at the middle position of the upper surface of the top plate 301. The output end of the second cylinder 5 is connected to a second telescopic column 501. An injection molding shielding frame 502 is fixedly connected to the bottom surface of the second telescopic column 501. An injection molding tube 503 passing through the top plate 301 is fixedly connected to one side of the upper surface of the injection molding shielding frame 502. When performing injection molding, the second cylinder 5 is operated. The output end of the second cylinder 5 pushes the second telescopic column 501 to lower the injection molding shielding frame 502. The injection molding shielding frame 502 covers the docked left mold seat 406 and right mold seat 407, and injection molding is performed into the left mold seat 406 and right mold seat 407 through the injection molding tube 503.

[0033] In summary, after injection molding, the plastic injection molding demolding device activates the drive motor 403. The output of the drive motor 403 rotates the threaded post 404, causing the moving blocks 405 engaged on both sides of the outer surface of the threaded post 404 to move. The moving blocks 405 on both sides respectively drive the left mold base 406 and the right mold base 407 to move in opposite directions, causing the left mold base 406 and the right mold base 407 to separate and fall onto the upper surface of the fixed base 1. Then, the first cylinder 411 is activated. The output end of cylinder 411 pushes telescopic column 412 to move. Telescopic column 412 then drives push seat 413 to move, pushing the injection molded part on the upper surface of fixed seat 1 to slide groove 414. The injection molded part slides from slide groove 414 into collection groove 419. When the injection molded part falls into collection groove 419, it presses down on collection box 418 and presses down on connecting spring 417. The connecting spring 417 is pressed and generates a restoring elastic force to push collection box 418 upward, thereby protecting the injection molded part from falling.
