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 for producing industrial products. Rubber and plastic injection molding are commonly used. Injection molding can be further categorized into compression molding and die casting. An injection molding machine (abbreviated as an injection molding machine or injection molding machine) is the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting materials using plastic molding molds. Injection molding is accomplished using an injection molding machine and molds.

[0003] The existing injection molds lack measures for rapid heat dissipation and shaping during use, resulting in slow product shaping. Moreover, when opening the mold, the upper mold moves upward 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 remove materials, and it is also inconvenient to clean and maintain the upper and lower molds. For this reason, we proposed an anti-cracking embedded injection molding device and its processing technology. Summary of the Invention

[0012] Preferably, an arc-shaped hole is provided on the arc-shaped frame, and the positioning shaft movably passes through the arc-shaped hole.

[0013] A processing technology for a crack-proof embedded injection molding device comprises the following steps:

[0014] Step 1: Before injection molding, place the reinforcement ribs into the placement groove, then close the upper mold and the lower mold, and perform injection molding through the injection port;

[0015] Step 2: During injection molding, the dual-axis motor drives the screw to rotate. At this time, the screw and the movable plate are in a semi-engaged state, allowing the screw to rotate continuously. The screw drives the cam to intermittently squeeze the vertical plate, thereby driving the lower mold to vibrate.

[0016] Step 3: The rotation of the screw also drives the active bevel gear to rotate, and the active bevel gear drives the driven bevel gear meshing with it to rotate, and the driven bevel gear drives the first rotating shaft to rotate, and the first rotating shaft drives the second rotating shaft to rotate through the pulley and belt, and the second rotating shaft drives the fan blades to rotate and blow air;

[0017] Step 4: After the product is finalized, when taking the material, the push rod motor will first drive the lifting frame to move upward. When the lifting frame moves upward, it will drive the double-sided rack, the first gear and the rotating plate to move upward synchronously, so that the upper mold and the lower mold can be opened. The double-sided rack will continue to move upward and will be limited by the cross plate. At this time, the push rod motor will continue to drive the lifting frame to move upward. When the first gear moves upward, it will rotate on the double-sided rack, thereby driving the rotating plate to rotate. In this way, the rotating plate drives the upper mold to flip upward;

[0018] Step 5: Then, the dual-axis motor drives in the reverse direction, and the movable plate and the screw are engaged again under the pressure of the compression force of the second spring. The rotation of the screw will drive the two movable plates to move away from each other. The movable plate will drive the arc frame to move through the positioning shaft, and the arc frame will drive the lower mold to move synchronously through the vertical plate. When the lower mold moves, it will drive the second gear to rotate on the single-sided rack, which will drive the lower mold to move and rotate at the same time.

[0019] The anti-cracking embedded injection molding device and its processing technology proposed by the present invention can bring the following beneficial effects:

[0020] The upper die can be moved up a certain distance by the lifting and flipping assembly, and then flipped over. This not only makes it easier for the upper die to be placed on its side for cleaning and maintenance, but also increases the distance between it and the lower die, increasing the operating and maintenance space.

[0021] The deflection drive assembly drives the air blowing and cooling assembly to work, so that the air blowing and cooling assembly can blow air to cool the lower mold and the upper mold, which is conducive to the rapid shaping of the product;

[0022] The deflection drive assembly can also drive the lower die to move horizontally, not only to move the lower die away from directly below the upper die, but also to drive the upper die to rotate sideways so that its opening faces downward, making it easier for workers to clean and maintain the interior of the lower die.

[0023] To sum up, this solution has a simple structure and novel design. It is not only convenient for blowing air to cool the upper and lower molds and improve the product shaping 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 remove materials and clean and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] A processing technology for a crack-proof embedded injection molding device comprises the following steps:

[0050] Step 1: Before injection molding, place the reinforcing rib 9 into the placement groove 8, then close the upper mold 4 and the lower mold 3, and perform injection molding through the injection port 12;

[0051] Step 2: During the injection molding process, 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, allowing the screw 604 to rotate continuously. The screw 604 drives the cam 606 to intermittently squeeze the vertical plate 611, thereby driving the lower mold 3 to vibrate.

[0052] Step 3: The rotation of the screw 604 also drives the active bevel gear 607 to rotate, and the active bevel gear 607 drives the driven bevel gear 704 meshing with it to rotate, and the driven bevel gear 704 drives the first rotating shaft 703 to rotate, and 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 blades 707 to rotate to blow air;

[0053] 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. 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. When the first gear 510 moves upward, it will rotate on the double-sided rack 508, thereby driving the rotating plate 511 to rotate. In this way, the rotating plate 511 drives the upper mold 4 to flip upward;

[0054] Step 5: Then, the dual-axis motor 603 is driven in the reverse direction, and the movable plate 608 and the screw 604 are meshed again under the pressure of the compression force of the second spring 613. The rotation of the screw 604 will drive the two movable plates 608 to move away from each other. 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 at the same time.

[0055] Working principle: Before injection molding, place the reinforcing rib 9 into the placement groove 8, use the reinforcing rib 9 to increase the strength of the product to prevent cracking, then close the upper mold 4 and the lower mold 3, and perform injection molding 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 thereof. 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. 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 turn upward 90 degrees, so that the upper mold 4 faces one side, and then the dual-axis motor 603 drives the screw 604 in the reverse direction 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 will make 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 while rotating 90 degrees, 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.

7. A processing technology for an anti-cracking embedded injection molding device, applicable to an anti-cracking embedded injection molding device according to any one of claims 1 to 6, characterized in that: The following steps are involved: Step 1: Before injection molding, place the reinforcement ribs into the placement groove, then close the upper mold and the lower mold, and perform injection molding through the injection port; Step 2: During injection molding, the dual-axis motor drives the screw to rotate. At this time, the screw and the movable plate are in a semi-engaged state, allowing the screw to rotate continuously. The screw drives the cam to intermittently squeeze the vertical plate, thereby driving the lower mold to vibrate. Step 3: The rotation of the screw also drives the active bevel gear to rotate, and the active bevel gear drives the driven bevel gear meshing with it to rotate, and the driven bevel gear drives the first rotating shaft to rotate, and the first rotating shaft drives the second rotating shaft to rotate through the pulley and belt, and the second rotating shaft drives the fan blades to rotate and blow air; Step 4: After the product is finalized, when taking the material, the push rod motor will first drive the lifting frame to move upward. When the lifting frame moves upward, it will drive the double-sided rack, the first gear and the rotating plate to move upward synchronously, so that the upper mold and the lower mold can be opened. The double-sided rack will continue to move upward and will be limited by the cross plate. At this time, the push rod motor will continue to drive the lifting frame to move upward. When the first gear moves upward, it will rotate on the double-sided rack, thereby driving the rotating plate to rotate. In this way, the rotating plate drives the upper mold to flip upward; Step 5: Then, the dual-axis motor drives in the reverse direction, and the movable plate and the screw are engaged again under the pressure of the compression force of the second spring. The rotation of the screw will drive the two movable plates to move away from each other. The movable plate will drive the arc frame to move through the positioning shaft, and the arc frame will drive the lower mold to move synchronously through the vertical plate. When the lower mold moves, it will drive the second gear to rotate on the single-sided rack, which will drive the lower mold to move and rotate at the same time.
