[0021] Please refer to Figures 1 to 4This utility model provides a static pressure casting production device, which aims to solve the problems of complex upper mold replacement process, cumbersome locking structure leading to low replacement efficiency, and insufficient automation of finished product demolding mechanism in the prior art.

[0022] The static pressure casting production device includes a lower mold 1 and a first fixing block 5 disposed above the lower mold 1. The lower mold 1 serves as the mounting base for the entire device. An upper mold 4 is slidably connected within the first fixing block 5. The upper mold 4 is used to cooperate with the lower mold 1 to complete the pressing and forming of the casting. A positioning hole 2 is provided inside the lower mold 1, and a first positioning rod 3 is fixed to the bottom of the upper mold 4. During the pressing process, the first positioning rod 3 is inserted and engaged with the positioning hole 2 to ensure the precise positioning of the upper mold 4 and the lower mold 1. The static pressure casting production device also includes a limiting component 6 for quick replacement of the upper mold 4. The limiting component 6 includes a first connecting block 601 fixed to one side of the first fixing block 5, and a slide rail 606 fixed to the inner wall of the first connecting block 601. A button 608 is slidably connected within the first connecting block 601, and sliders 607 are connected to both sides of the button 608. The sliders 607 are slidably connected to the slide rail 606, allowing the button 608 to slide stably in the vertical direction within the first connecting block 601. A symmetrical rotating block 605 is rotatably connected to the outer side of the button 608. A third connecting block 604 is slidably connected inside the first connecting block 601. The third connecting block 604 is linked to the rotating block 605. Specifically, the two ends of the rotating block 605 are rotatably connected to the outer side of the button 608 and the outer side of the third connecting block 604 respectively through a rotating shaft. When the button 608 slides down, the lever transmission of the rotating block 605 can drive the third connecting block 604 to slide vertically upward along the through groove in the first connecting block 601. A spring 609 is pressed between the button 608 and the third connecting block 604. The two ends of the spring 609 abut against the button 608 and the third connecting block 604 respectively, providing a reset force for the limiting component 6. A limiting block 603 is fixed at the bottom of the third connecting block 604. A second connecting block 602 is fixed on one side of the upper mold 4. Under the elastic force of the spring 609, the limiting block 603 can be detachably inserted into the second connecting block 602, thereby locking the upper mold 4 inside the first fixing block 5.

[0023] The demolding assembly 7 includes a lead screw 701 rotatably disposed within the lower mold 1, with the axis of the lead screw 701 arranged horizontally. A second fixing block 711 is slidably connected within the lower mold 1 along the axis of the lead screw 701, and the second fixing block 711 is threadedly connected to the lead screw 701. Rotation of the lead screw 701 can drive the second fixing block 711 to slide horizontally. A first connecting plate 704 is fixed within the lower mold 1, and a sleeve 703 is fixed on the first connecting plate 704, with the axis of the sleeve 703 arranged vertically. The demolding assembly 7 also includes a second connecting plate 712, with a second positioning rod 702 and a fixing plate 710 fixed at the bottom of the second connecting plate 712. The axis of the second positioning rod 702 is arranged vertically, and the second positioning rod 702 is slidably connected within the sleeve 703 to provide guidance for the vertical movement of the second connecting plate 712. Pulleys 705 are rotatably connected to both sides of the second fixing block 711, and the fixing plate 710 is disposed on the second connecting plate 712. On the bottom surface of the mold 1, an inclined groove is provided on the fixed plate 710, and a pulley 705 rolls in the inclined groove. This cooperative structure of pulley 705 and inclined groove can accurately convert the horizontal movement of the second fixed block 711 into the vertical lifting movement of the second connecting plate 712. A fourth connecting block 707 is fixed inside the lower mold 1, and a through hole is provided on the fourth connecting block 707. A first connecting rod 706 and a second connecting rod 709 are fixed on the second connecting plate 712. The first connecting rod 706 and the second connecting rod 709 are parallel and vertically arranged, and slide through the through hole of the fourth connecting block 707. A push plate 708 slides inside the lower mold 1. The push plate 708 is fixedly connected to one end of the first connecting rod 706 and one end of the second connecting rod 709. When the second connecting plate 712 moves upward, the push plate 708 can be driven to rise smoothly through the synchronous transmission of the first connecting rod 706 and the second connecting rod 709, thereby ejecting the casting in the lower mold 1.

[0024] In a preferred embodiment, to make the unlocking and resetting actions of the limiting component 6 smoother, the button 608 slides vertically within the first connecting block 601, while the third connecting block 604 slides vertically along the through groove within the first connecting block 601. This ensures that the downward pressure of the button 608 and the upward force of the third connecting block 604 act in opposite directions on the same straight line, thus avoiding the generation of lateral torque.

[0025] In a preferred embodiment, in order to make the locking state of the limiting component 6 more reliable and have clear tactile feedback, the two ends of the spring 609 abut against the inner surface of the button 608 and the inner surface of the third connecting block 604, respectively. In the natural state, the spring 609 applies a continuous pushing force to the third connecting block 604 to ensure that the limiting block 603 always remains in the plugged state with the second connecting block 602.

[0026] In a preferred embodiment, in order to make the force transmission inside the limiting component 6 more efficient and stable, the rotating block 605 is hinged to the outside of the button 608, and the other end of the rotating block 605 is linked to the third connecting block 604. This dual-shaft connection method constitutes a stable linkage mechanism, ensuring that the linear motion of the button 608 can be accurately converted into the linear motion of the third connecting block 604.

[0027] As a preferred embodiment, in order to make the drive structure of the demolding assembly 7 more compact and easier to install, the axis of the lead screw 701 is set in the horizontal direction, and the second fixing block 711 slides horizontally along the axis of the lead screw 701. This layout makes full use of the lateral space at the bottom of the lower mold 1.

[0028] In a preferred embodiment, to make the horizontal-to-vertical motion transition in the demolding assembly 7 more reliable, a fixed plate 710 is disposed on the bottom surface of the second connecting plate 712, an inclined slide is formed on the fixed plate 710, and a pulley 705 rolls in the inclined slide. By controlling the angle of the inclined slide, the demolding stroke and speed can be precisely set.

[0029] In a preferred embodiment, in order to ensure the stability and precise guidance of the second connecting plate 712 during the lifting process, the axis of the second positioning rod 702 and the axis of the sleeve 703 are both set in the vertical direction. The second positioning rod 702 slides vertically in the sleeve 703, which effectively prevents the second connecting plate 712 from tilting or swaying when subjected to force.

[0030] As a preferred embodiment, in order to ensure that the push plate 708 is subjected to uniform force and moves smoothly when ejecting the casting, the first connecting rod 706 and the second connecting rod 709 are both parallel and vertically arranged in the through hole of the fourth connecting block 707. The structure of the two rods pushing synchronously avoids the tilting of the push plate 708 and the jamming of the casting that may be caused by single-point force.

[0031] Working principle: When it is necessary to replace the upper mold 4, press the button 608 down. The button 608 slides down on the slide rail 606 on the inner wall of the first connecting block 601 through the sliders 607 on both sides. At the same time, the button 608 slides up through the rotating block 605 connected to the outside, which in turn moves the third connecting block 604 in the first connecting block 601 upward. The downward moving button 608 and the upward moving third connecting block 604 together squeeze the spring 609 between them. As the third connecting block 604 rises, the limiting block 603 fixed at its bottom also moves upward, and finally completely disengages from the insertion state inside the second connecting block 602. At this time, the lock between the upper mold 4 and the first fixing block 5 is released, and the upper mold 4 can be slid out for replacement. When the casting needs to be demolded after molding, the external drive mechanism rotates the lead screw 701. The lead screw 701 pushes the second fixed block 711 to move horizontally through the threaded transmission. The pulleys 705 on both sides of the second fixed block 711 roll in the inclined groove of the fixed plate 710. Due to the existence of the inclined groove, the horizontal movement of the second fixed block 711 is converted into the vertical upward movement of the second connecting plate 712. The upward movement of the second connecting plate 712 is synchronously transmitted to the push plate 708 through the fixedly connected first connecting rod 706 and second connecting rod 709. The push plate 708 rises smoothly under the synchronous push of the two rods, pushing the finished casting in the lower mold 1 upward and completing the entire demolding process.
