[0002] Railway train latches are an important component of railway freight cars, mainly used to secure and protect cargo. The cutting precision of the latch seat has a significant impact on the assembly quality and safety of the doors.

[0003] Currently, existing casting devices generally employ a single ejector rod or manual demolding. The uneven force distribution of a single ejector rod easily leads to localized stress concentration in the thin-walled area of ​​the door latch seat, resulting in a high rate of crack defects. Manual demolding, requiring operators to use tools such as pry bars and hammers, not only increases labor intensity but also poses a challenge. Therefore, to better facilitate the demolding of door latch seats, promote technological progress in the industry, and enhance core technological competitiveness, this application proposes a new implementation scheme for door latch seat casting devices that differs from existing technologies. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems of high defect rate and high labor intensity in existing products, and to propose a door latch casting device that is easy to demold.

A mounting plate is fixedly connected to the top of the workbench, and a lower mold is fixedly connected to the top of the mounting plate. An upper mold is provided on the top of the lower mold. Mold core cavities are provided inside the upper mold and the lower mold. An installation groove is provided at one end of the lower mold. Multiple installation holes are provided at the bottom of the mold core cavity of the lower mold. The installation holes communicate with the installation groove. Ejector pins are slidably connected in the installation holes. Rollers are fixedly connected to the bottom ends of the ejector pins. A support plate is slidably connected in the installation groove. Multiple installation blocks are fixedly connected to the top of the support plate. The top of the installation blocks is provided with an inclined surface, and the rollers contact the inclined surface.

[0006] Furthermore, a plurality of support rods are fixedly connected to the top of the mounting plate, and a connecting plate is fixedly connected to the top of the plurality of support rods. A sliding plate is slidably sleeved between the plurality of support rods, and the upper mold is fixed to the bottom of the sliding plate by bolts.

[0007] Furthermore, a hydraulic rod is fixedly connected to the top of the connecting plate, and the bottom end of the hydraulic rod is fixedly connected to the top of the slide plate.

[0008] Furthermore, the top of the upper mold and the top of the slide plate are provided with pouring ports and vents.

A lower mold 5 is bolted to the top of the mounting plate 4. An upper mold 10 is mounted on the top of the lower mold 5. Mold core cavities 14 are provided inside both the upper mold 10 and the lower mold 5. An installation groove 13 is provided at one end of the lower mold 5. Multiple installation holes 15 are provided at the bottom of the mold core cavity 14 of the lower mold 5, communicating with the installation groove 13. Ejector pins 18 are slidably connected within the installation holes 15. Rollers 19 are bolted to the bottom ends of the ejector pins 18. A support plate is slidably connected within the installation groove 13. 16. One end of the support plate 16 is fixed with a handle 17 by bolts. The top of the support plate 16 is fixed with multiple mounting blocks 20 by bolts. The top of the mounting block 20 is provided with an inclined surface 21. The roller 19 contacts the inclined surface 21. Pulling the handle 17 outward will drive the support plate 16 to move outward, thereby driving the mounting block 20 to move outward. During the movement, the mounting block 20 gradually moves to below the roller 19. Under the pressure of the mounting block 20, the roller 19 and the ejector pin 18 move upward, thereby causing the ejector pin 18 to push out of the mounting hole 15, and then causing the door latch seat to push out of the lower mold 5, so that the door latch seat can be demolded.

[0018] Multiple support rods 6 are welded to the top of the mounting plate 4. A connecting plate 7 is welded to the top of the multiple support rods 6. A sliding plate 9 is slidably connected between the multiple support rods 6. The upper mold 10 is fixed to the bottom of the sliding plate 9 by bolts. A hydraulic rod 8 is fixed to the top of the connecting plate 7 by bolts. The bottom end of the hydraulic rod 8 is fixedly connected to the top of the sliding plate 9. Under the drive of the hydraulic rod 8, the sliding plate 9 moves along the support rods 6, thereby driving the upper mold 10 to move, thus realizing the opening and closing of the upper mold 10 and the lower mold 5. The top of the upper mold 10 and the top of the slide plate 9 are provided with a pouring port 11 and a vent hole 12. The pouring port 11 and the vent hole 12 are connected to the mold core cavity 14 of the upper mold 10.

[0019] The outer wall of the handle 17 is provided with anti-slip grooves, which facilitates the operation of the handle 17.

[0020] The working principle of this embodiment is as follows: In the initial state, the upper mold 10 and the lower mold 5 are separated, and the ejector pin 18 is completely retracted into the mounting hole 15. First, the hydraulic rod 8 is started by controlling the control panel 2. Under the tension of the hydraulic rod 8, the slide plate 9 moves downward along the support rod 6, thereby moving the upper mold 10 downward, so that the upper mold 10 and the lower mold 5 are closed together. Then, the casting liquid is injected into the mold cavity 14 from the casting port 11, and then waits for molding. After molding, the upper mold 10 separates from the lower mold 5 under the contraction of the hydraulic rod 8. Then, the handle 17 is pulled outward to move the support plate 16 outward, thereby moving the mounting block 20 outward. During the movement, the mounting block 20 gradually moves to below the roller 19. Under the pressure of the mounting block 20, the roller 19 and the ejector pin 18 move upward, thereby causing the ejector pin 18 to push out of the mounting hole 15, and then causing the door latch seat to push out of the lower mold 5, so that the door latch seat can be demolded. Then the door latch seat can be taken out.
