[0015] Compared with the prior art, the beneficial effects of the present invention are: By setting up a mold closing mechanism and a mold release mechanism, when the lower mold moves below the upper mold, the upper and lower molds perform a mold closing operation. After injection molding, the upper and lower molds separate. Then, the rotating disk rotates, the first spur gear contacts the first toothed plate, and the C-shaped block moves upward. The displacement of the C-shaped block drives the shell to move out of the lower mold. At this time, the fixing block moves out of the fixing groove, and the fixing of the C-shaped block is released. The C-shaped block can then be moved out from the top of the displacement frame, separating the two C-shaped blocks, thereby removing the shell. This facilitates automatic demolding of the molded shell. Furthermore, while removing the shell from one lower mold, the other lower mold can continue injection molding, improving production efficiency. Attached Figure Description

[0020] Please see Figures 1 to 9In this embodiment of the invention, an electronic component housing production equipment includes an upper mold 1, a lower mold 2, and a base 8. The lower mold 2 has an installation groove 4 on its inner wall and a pin groove 3 at its bottom. Two C-shaped blocks 5 are slidably connected to the inner wall of the installation groove 4. The upper mold 1 and lower mold 2 are closed by a mold-closing mechanism 6. The formed housing is demolded by a demolding mechanism 7. The mold-closing mechanism 6 includes a support base 601, which is fixedly connected to the top of the base 8. A rotating disk 602 is rotatably connected to the top of the support base 601.

The movement of the crossbar 608 causes the slider 611 to move, and the slider 611 slides in the guide groove 612 to push the movable plate 609 to move. The movement of the movable plate 609 causes the positioning plate 610 to move, and the positioning plate 610 moves and inserts into the positioning groove 604 to position the rotating disk 602, preventing positional deviation when the upper mold 1 and the lower mold 2 are closed.

[0022] Please refer to this carefully. Figures 6 to 9The demolding mechanism 7 includes a first toothed plate 701 and a second toothed plate 702. The first toothed plate 701 and the second toothed plate 702 are fixedly connected to the top of the base 8 and located below the rotating disk 602. The first toothed plate 701 and the second toothed plate 702 are located on both sides of the motor 603. A displacement frame 705 extending into the lower mold 2 is slidably connected inside the rotating disk 602. A displacement groove 706 for the displacement frame 705 to slide is opened inside the second toothed plate 702. A threaded rod 704 passing through the displacement frame 705 is rotatably connected inside the rotating disk 602. A first spur gear 703 is fixedly connected to the bottom end of the threaded rod 704. The demolding mechanism 7 also includes a connecting groove 707. 707 is located at the bottom of the C-shaped block 5. A fixing groove 708 is provided on the inner wall of the connecting groove 707. A fixing block 709 extending out of the displacement frame 705 is slidably connected inside the displacement frame 705. A first spring 710 is connected between the fixing block 709 and the displacement frame 705. A top rod 711 is slidably connected inside the displacement frame 705 below the fixing block 709. A second spring 712 is connected between the top rod 711 and the displacement frame 705. A second spur gear 713 is rotatably connected inside the displacement frame 705 on the outer wall of the top rod 711. A pressing block 714 is slidably connected inside the displacement frame 705 on the outer wall of the second spur gear 713. The pressing block 714 extends out of the displacement frame 705.

[0023] In this embodiment: the displacement frame 705 is connected into the connecting groove 707, and the fixing block 709 is engaged into the fixing groove 708 by the elastic force of the first spring 710, fixing the C-shaped block 5 to the top of the displacement frame 705. The displacement frame 705 is located at the bottom of the displacement groove 706, pressing the C-shaped block 5 into the mounting groove 4. The pin is inserted into the pin groove 3. When the lower mold 2 moves below the upper mold 1, the hydraulic cylinder 606 rotates, driving the movable seat 607 and the upper mold 1 to move downwards. The upper mold 1 and the lower mold 2 perform a mold closing operation. After injection molding, the upper mold 1 and the lower mold 2 separate, and the shell is formed in the lower mold 2. Then the motor 603 operates. The rotating disk 602 rotates, and during this rotation, the first spur gear 703 contacts the first toothed plate 701. The first spur gear 703 moves along the first toothed plate 701, thus rotating. The rotation of the first spur gear 703 drives the threaded rod 704 to rotate, which in turn drives the displacement frame 705 to move. The displacement frame 705 moves within the displacement groove 706, causing the C-shaped block 5 to move upward. The displacement of the C-shaped block 5 causes the housing to move out of the lower mold 2. When the displacement frame 705 moves to the top of the displacement groove 706, the extrusion block 714 contacts the inner wall of the displacement groove 706, pushing the extrusion block 714 relative to the inner wall of the groove. The displacement frame 705 is displaced, and the displacement of the pressing block 714 drives the second spur gear 713 to rotate. The rotation of the second spur gear 713 drives the push rod 711 to move, compressing the second spring 712. The displacement of the push rod 711 pushes the fixing block 709 to move, compressing the first spring 710. The fixing block 709 moves out of the fixing groove 708, releasing the fixation of the C-shaped block 5. At this time, the C-shaped block 5 can be removed from the top of the displacement frame 705, separating the two C-shaped blocks 5, thereby removing the housing. Then, the C-shaped block 5 is placed back on the top of the displacement frame 705, and the rotation of the second toothed plate 702 drives the lower mold 2 to move and reset. The first spur gear 703 contacts the second toothed plate 702, and the first spur gear 703 rotates along the second toothed plate 702. The rotation of the first spur gear 703 drives the displacement frame 705 to move. At this time, the extrusion block 714 separates from the inner wall of the displacement groove 706, and the fixing block 709 engages in the fixing groove 708, fixing the C-shaped block 5 to the top of the displacement frame 705. The displacement frame 705 moves downward to press the C-shaped block 5 into the mounting groove 4, which facilitates the automatic demolding operation of the molded shell. When the shell on one lower mold 2 is removed, the other lower mold 2 can still continue to perform injection molding operation, which improves production efficiency.
