Description

Technical Field

[0001] The utility model relates to the technical field of casting molds, in particular to a side drawing structure of a low-pressure mold for a new energy turbine housing. Background Art

[0002] With the increasing global emphasis on clean energy and sustainable development, new energy technologies have been booming. Among them, the new energy turbine housing, as a key technology, is playing an important role. In the field of traditional energy, turbine housings have been widely used, which can improve energy conversion efficiency and enhance power output. In the new energy field, the turbine housing technology also faces new challenges and opportunities. The characteristics of new energy require the turbine housing to have higher performance and adaptability. And the energy density of new energy is relatively low, requiring a more efficient air compression and energy conversion mechanism, which puts higher requirements on the design and manufacturing of the turbine housing. The new energy turbine housing can work stably in a more demanding environment. At the same time, advanced manufacturing processes also ensure the high precision and high quality of the new energy turbine housing. During the production of the new energy turbine housing, the core in the mold needs to be inserted or removed for subsequent production. The traditional method is to manually insert the ejector block into the core hole in the mold to fix the core in the mold cavity, and the core is removed by manually pulling out the slide block, and the upper template ejects the end face of the casting to drive the core to demold together. If the operator forgets to pull out the slide block when opening the mold, this method will cause the core to be broken and remain in the mold cavity during demolding, and the time for cleaning the residual sand is long, affecting the production capacity and unable to produce continuously, and it is easy to damage the inner cavity of the mold. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a side drawing structure of a low-pressure mold for a new energy turbine housing in view of the defects of the prior art.

[0004] To solve the above technical problems, the utility model provides the following technical solutions:

[0005] A side-drawing structure for the low-pressure mold of a new energy turbine pressure housing, comprising a buckle assembly arranged on the lower module connecting plate and a closer assembly arranged on the side of the upper module, characterized in that: the buckle assembly includes a support plate and a hook plate. The lower end of the support plate is connected to the lower module connecting plate, and the lower end of the hook plate is hinged to the upper end of the support plate. The closer assembly includes a pull pin mechanism, a first fixed frame, a rotating gear, and a core column. One end of the core column passes through the inner cavity of the upper module, and the other end is connected to the pull pin mechanism. A first spring is sleeved on the core column, and the two ends of the first spring respectively abut against the upper module and the rotating gear. The first fixed frame is connected to the side of the upper module. The rotating gear is movably sleeved in the fixing hole of the first fixed frame. A first limiting block and a convex block are arranged on the outer surface of the rotating gear. A second limiting block matched with the first limiting block is arranged in the fixing hole. The convex block is matched with the hook at the upper end of the hook plate. When the rotating gear moves upward with the upper module, the hook can push the convex block to make the rotating gear rotate, and the first limiting block and the second limiting block are separated from each other.

[0006] Further, the pull pin mechanism includes a second fixed frame, a gear sleeve, and a pull pin rod. The second fixed frame is connected to the first fixed frame.

[0010] Further, the first spring abuts against a directional fixed circular plate fixedly connected to the upper module, and the core column passes through the inner cavity of the upper module through a through hole in the center of the directional fixed circular plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: 1. It is used for fixing and demolding the sand core in the inner cavity of the casting. Through mold opening, the upper mold drives the buckle assembly to drive the closer device to automatically eject the core, realizing semi-automatic production, reducing the mold opening and core pulling process time of the mold, improving production efficiency, and reducing production costs. 2. This semi-automatic core pulling structure prevents the problem that the operator forgets to pull out the slider during mold opening, resulting in the reverse buckle of the core during demolding and remaining broken in the mold cavity, saving the time for cleaning residual sand and preventing damage to the inner cavity of the mold. 3. It can be designed and adjusted according to the shapes and sizes of different molds and cores, and has strong adaptability. Description of the Drawings

[0020] In order to deepen the understanding of the utility model, the following will further elaborate on the utility model in conjunction with the drawings. This embodiment is only used to explain the utility model and does not limit the protection scope of the utility model.

[0021] Figures 1-7Shows a specific embodiment of a side-drawing structure for the low-pressure die of a new energy turbine pressure housing, including a buckle assembly arranged on the lower module connecting plate 1 and a closer assembly arranged on the side of the upper module 2.

[0022] The buckle assembly includes a support plate 3 and a hook plate 4. The lower end of the support plate 3 is connected to the lower module connecting plate 1, the lower end of the hook plate 4 is hinged to the upper end of the support plate 3, and a second spring 15 is connected between the support plate 3 and the hook plate 4.

[0023] The closer assembly includes a pull pin mechanism, a first fixed frame 5, a rotating gear 6, and a core column 7. A directional fixed circular plate 16 is fixedly connected to the side of the upper module 2, and a through hole is provided in its center. The first fixed frame 5 is connected to the side of the upper module 2 and covers the outside of the directional fixed circular plate 16. One end of the core column 7 passes through the through hole and is arranged in the inner cavity of the upper module 2, and the other end is connected to the pull pin mechanism. A first spring 8 is sleeved on the core column 7, and both ends of the first spring 5 respectively abut against the directional fixed circular plate 16 and the rotating gear 6. The rotating gear 6 is movably arranged in the fixed hole of the first fixed frame 5. The outer surface of the rotating gear 6 is provided with a first limit block 61 and a convex block 62, and a second limit block 52 matched with the first limit block 61 is arranged in the fixed hole 51. The convex block 62 is matched with the hook 41 at the upper end of the hook plate 4.

[0024] The pull pin mechanism includes a second fixed frame 9, a gear sleeve 10, a first pull pin rod 11, a second pull pin rod 12, and a third pull pin rod 13. The second fixed frame 9 is connected to the outside of the first fixed frame 5. The inner side of the gear sleeve 10 movably connected to the second fixed frame 9 meshes with the rotating gear 6. The core column 7 is connected in the gear sleeve 10. One ends of the first pull pin rod 11, the second pull pin rod 12, and the third pull pin rod 13 are hinged to each other. The other end of the first pull pin rod 11 is a free end. The other end of the second pull pin rod 12 is hinged to the second fixed frame 9 through a hinge block 14, and the hinge block 14 is rotatably connected to the second fixed frame 9. The other end of the third pull pin rod 13 is hinged to the outside of the gear sleeve 10.

[0025] The working process and principle of the above embodiment are as follows:

[0026] At the beginning, the states of all parts are as Figure 6As shown, the upper module 2 and the lower module 17 are in a separated state. After the core 18 is placed into the inner cavity of the upper module 2, the mold is closed. The first pull pin rod 11 is pushed, so that the second pull pin rod 12 and the third pull pin rod 13 are in a straight line coaxial with the core column 7. At this time, the gear sleeve 10 drives the core column 7 to move towards the core 18 and insert and fix the core 18. The rotating gear 6 rotates forward along the fixing hole 51 and compresses the first spring 8. At this time, the first limiting block 61 comes to the inner side of the first fixing frame 5. The first pull pin rod 11 is pressed downward counterclockwise, and the gear sleeve 10 drives the rotating gear 6 to rotate counterclockwise until the first limiting block 61 rotates to the inner side of the second limiting block 52 and abuts against the second limiting block 52. The operator releases the first pull pin rod 11 to complete the fixing of the core 18, as Figure 7 shown. When the mold needs to be opened after pouring, the rotating gear 6 moves upward with the upper module 2, and the hook 41 at the top of the hook 4 plate generates a downward pressure on the convex block 62. The rotating gear 6 rotates clockwise until the first limiting block 61 is disengaged from the limit of the second limiting block 52. The rotating gear 6 moves outward under the elastic force of the first spring 8, and at the same time pushes the gear sleeve 10 and the core column 7 to move outward, and the core column 7 automatically disengages from the core 18.

However, the above content does not limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention shall fall within the protection scope of the present invention.
