Description

Technical Field

[0001] The invention belongs to the technical field of injection molding, and in particular relates to an anti-cracking embedded injection molding device and a processing technology thereof. Background Art

[0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machine (abbreviated as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds.

[0003] The existing injection molds lack measures for rapid heat dissipation and shaping during use, resulting in slow product shaping. In addition, when opening the mold, the upper mold moves up to complete the mold opening. Usually, the distance between the upper mold and the lower mold is close, resulting in insufficient operating space, making it inconvenient for workers to quickly take out materials, and it is also inconvenient to clean and maintain the upper and lower molds.

[0014] The anti-cracking embedded injection molding device and its processing technology proposed by the present invention can bring the following beneficial effects: The lifting and flipping assembly can drive the upper die to move up a certain distance first, and then flip it over.

It is not only convenient for blowing air to cool the upper and lower molds and improve the product molding speed, but also after the mold is opened, the upper mold moves up and deflects to one side, while the lower mold moves away and flips to one side. This not only increases the operating space between the upper and lower molds, but also makes it convenient for staff to take materials and clean and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] A processing technology of an anti-cracking embedded injection molding device comprises the following steps: Step 1: Before injection molding, the reinforcing rib 9 is placed in the placement groove 8, and then the upper mold 4 and the lower mold 3 are molded together, and injection molding is performed through the injection port 12; Step 2: During the injection molding, the dual-axis motor 603 drives the screw 604 to rotate. At this time, the screw 604 and the movable plate 608 are in a semi-engaged state, so that the screw 604 can continue to rotate. The screw 604 drives the cam 606 to intermittently extrude the vertical plate 611, thereby driving the lower mold 3 to vibrate; Step 3: The screw 604 rotates and drives the active bevel gear 607 to rotate. The active bevel gear 607 drives the driven bevel gear 704 meshing therewith to rotate. The driven bevel gear 704 drives the first rotating shaft 703 to rotate. The first rotating shaft 703 drives the second rotating shaft 706 to rotate through the pulley 708 and the belt 709. The second rotating shaft 706 drives the fan blades 707 to rotate to blow air. Step 4: After the product is finalized, when taking the material, the push rod motor 502 is used to drive the lifting frame 505 to move upward. When the lifting frame 505 moves upward, it will drive the double-sided rack 508, the first gear 510 and the rotating plate 511 to move upward synchronously, so that the upper mold 4 and the lower mold 3 can be opened, and the double-sided rack 508 will be limited by the horizontal plate 503 when it continues to move upward. At this time, the push rod motor 502 continues to drive the lifting frame 505 to move upward. When the first gear 510 moves upward, it will rotate on the double-sided rack 508, thereby driving the rotating plate 511 to rotate, so that the rotating plate 511 drives the upper mold 4 to flip upward; Step five: Subsequently, the dual-axis motor 603 is driven in reverse, and the compressive elastic force of the second spring 613 causes the movable plate 608 to mesh with the screw 604 again, so that the rotation of the screw 604 will drive the two movable plates 608 to move away from each other, and the movable plate 608 will drive the arc frame 610 to move through the positioning shaft 609, and the arc frame 610 will drive the lower mold 3 to move synchronously through the vertical plate 611. When the lower mold 3 moves, it will drive the second gear 15 to rotate on the single-sided rack 14, so that the lower mold 3 will be driven to move and rotate at the same time.

[0040] Working principle: Before injection molding, the reinforcing ribs 9 are placed in the placement grooves 8, and the reinforcing ribs 9 are used to increase the strength of the product to prevent cracking. Then the upper mold 4 and the lower mold 3 are molded together, and injection molding is performed through the injection port 12. Figure 1In the state shown, during injection molding, the dual-axis motor 603 drives the screw 604 to rotate clockwise. At this time, the movable plate 608 is located at the rightmost side of the thread on the screw 604, and the vertical plate 611 compresses the second spring 613 at the same time. At this time, the movable plate 608 and the screw 604 are in a semi-engaged state, so that the screw 604 can continue to rotate. The screw 604 will drive the cam 606 to intermittently squeeze the vertical plate 611, thereby driving the lower mold 3 to vibrate. The rotation of the screw 604 also drives the active bevel gear 607 to rotate, and the active bevel gear 607 drives the meshing bevel gear 607 to rotate. The driven bevel gear 704 rotates, and the driven bevel gear 704 drives the first rotating shaft 703 to rotate. The first rotating shaft 703 drives the second rotating shaft 706 to rotate through the pulley 708 and the belt 709, and the second rotating shaft 706 drives the fan blade 707 to rotate and blow air, which is conducive to rapid cooling and shaping. After the product is shaped, when taking the material, the lifting frame 505 is first driven to move up by the push rod motor 502. When the lifting frame 505 moves up, it will drive the double-sided rack 508, the first gear 510 and the rotating plate 511 to move up synchronously, so that the upper mold 4 and the lower mold 3 The mold is opened, and the double-sided rack 508 continues to move upward and is limited by the horizontal plate 503. At this time, the push rod motor 502 continues to drive the lifting frame 505 to move upward, so that the first gear 510 will rotate on the double-sided rack 508 when moving upward, so that the rotating plate 511 drives the upper mold 4 to flip upward 90 degrees, so that the upper mold 4 faces one side, and then the double-axis motor 603 drives the screw 604 to rotate counterclockwise. Under the compression force of the second spring 613, the second spring 613 squeezes the vertical plate 611 through the squeezing plate 614, which makes the moving plate 608 It meshes with the screw 604 again, so that the rotation of the screw 604 will drive the two movable plates 608 to move away from each other, and the movable plate 608 will drive the arc frame 610 to move through the positioning shaft 609, and the arc frame 610 will drive the lower mold 3 to move synchronously through the vertical plate 611. When the lower mold 3 moves, it will drive the second gear 15 to rotate on the single-sided rack 14, which will drive the lower mold 3 to move and rotate 90 degrees at the same time, so that the lower mold 3 faces one side, which makes it inconvenient to separate the lower mold 3 and the upper mold 4, and both face one side, which is convenient for material removal and cleaning and maintenance.

9. A processing technology for an anti-cracking embedded injection molding device, applicable to an anti-cracking embedded injection molding device as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: before injection molding, the reinforcing rib (9) is placed in the placement groove (8), and then the upper mold (4) and the lower mold (3) are molded together, and injection molding is performed through the injection port (12); Step 2: During injection molding, the dual-axis motor (603) drives the screw (604) to rotate. At this time, the screw (604) and the movable plate (608) are in a semi-engaged state, so that the screw (604) can continue to rotate. The screw (604) drives the cam (606) to intermittently extrude the vertical plate (611), thereby driving the lower mold (3) to vibrate; Step 3: The screw (604) rotates and drives the active bevel gear (607) to rotate. The active bevel gear (607) drives the driven bevel gear (704) meshing therewith to rotate. The driven bevel gear (704) drives the first rotating shaft (703) to rotate. The first rotating shaft (703) drives the second rotating shaft (706) to rotate through the pulley (708) and the belt (709). The second rotating shaft (706) drives the fan blades (707) to rotate to blow air. Step 4: After the product is finalized, when taking the material, the lifting frame (505) is first driven upward by the push rod motor (502). When the lifting frame (505) moves upward, it will drive the double-sided rack (508), the first gear (510) and the rotating plate (511) to move upward synchronously, so that the upper mold (4) and the lower mold (3) can be opened, and the double-sided rack (508) will be limited by the horizontal plate (503) when it continues to move upward. At this time, the push rod motor (502) continues to drive the lifting frame (505) to move upward. When the first gear (510) moves upward, it will rotate on the double-sided rack (508), thereby driving the rotating plate (511) to rotate, so that the rotating plate (511) drives the upper mold (4) to flip upward; Step 5: Subsequently, the dual-axis motor (603) is driven in the reverse direction, and the compressive force of the second spring (613) causes the movable plate (608) to mesh with the screw rod (604) again, so that the rotation of the screw rod (604) drives the two movable plates (608) to move away from each other, and the movable plate (608) drives the arc frame (610) to move through the positioning shaft (609), and the arc frame (610) drives the lower mold (3) to move synchronously through the vertical plate (611). When the lower mold (3) moves, it drives the second gear (15) to rotate on the single-sided rack (14), so that the lower mold (3) is driven to move and rotate at the same time.
