Description

Technical fields:

[0001] This utility model relates to the field of sand core manufacturing, and in particular to a quick-release sand core blowing plate structure. Background technology:

[0002] The sand core mold is used to make sand cores. During the production process, sand needs to be poured into the sand core mold. Currently, sand is supplied through a sand supply pipeline and a liftable sand filling mechanism connected in sequence. The liftable sand filling mechanism is located above the sand core mold and can move up and down. When the liftable sand filling mechanism descends to the lowest position, it contacts the sand core mold to fill the sand. When the liftable sand filling mechanism rises to the highest position, it disengages from the sand core mold to adjust the speed of the sand core mold or replace the sand blowing plate on the liftable sand filling mechanism. Currently, the sand blowing plate is rectangular and is locked to the liftable sand filling mechanism from bottom to top by more than ten sets of countersunk bolts. Since different sand core molds and sand blowing plates are needed to make sand cores for different products, the sand blowing plate needs to be replaced frequently. However, due to the limited space for replacement, the current installation and locking structure of the sand blowing plate is not reasonably designed, resulting in difficulty and low efficiency in replacing the sand core under limited space. Summary of the Invention:

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a quick-release sand core blowing plate structure, which is reasonably designed and convenient for disassembly and replacement.

[0020] The quick-release sand core blowing plate structure of this utility model includes a liftable sand filling mechanism 1 located above the sand core mold 01 and a blowing plate 2 located on the lower surface of the liftable sand filling mechanism, wherein the sand core mold includes a left half mold and a right half mold that can be relatively close to or far away from each other.

[0021] The sand blowing plate 2 is a plate with a T-shaped cross section. The lower part of the liftable sand filling mechanism is provided with a T-shaped groove 3 that slides and connects with the sand blowing plate. When it is necessary to replace the sand blowing plate on the liftable sand filling mechanism, first push the sand blowing plate along the T-shaped groove to remove the sand blowing plate from the liftable sand filling mechanism. Then, replace it with another sand blowing plate that is compatible with the new sand core mold in the T-shaped groove to complete the replacement. The replacement of the sand core mold is convenient and quick.

[0022] To achieve a seal, a rubber layer 4 is attached to the lower surface of the sand blowing plate, and a sealing ring 5 is provided on the upper surface of the sand blowing plate. The rubber layer 4 and the sealing ring 5 can prevent sand from overflowing.

[0023] The liftable sand filling mechanism can be driven to lift by a hydraulic cylinder or electric push rod 10. When the liftable sand filling mechanism is lowered to the lowest position, the lower surface of the rubber layer 4 abuts against the upper surface of the sand core mold.

[0024] To achieve sand passage, the sand blowing plate is a rectangular plate with a row of perforations 6 running from its upper surface to its lower surface in the middle of the sand blowing plate. The perforations 6 are arranged along the length of the sand blowing plate. The lifting sand filling mechanism 1 has several vertical sand passage pipes 7 for sand drop. After the sand blowing plate is inserted into the T-slot, the lower end of the vertical sand passage pipe is connected to the upper end of the perforation 6. The upper end of the vertical sand passage pipe 7 is connected to the sand supply pipeline, etc.

[0025] To achieve cooling, cooling water channels 8 are provided on both sides of the perforation 6 on the sandblasting plate 2. The cooling water channels pass through both end faces of the sandblasting plate, the axis of the cooling water channels is perpendicular to the axis of the perforation, and the axis of the cooling water channels is set along the length of the sandblasting plate.

[0026] For a reasonable design, the upper surface of the aforementioned sandblasting plate is provided with a recess 9 inside the sealing ring 5.

[0027] The lower part of the aforementioned liftable sand filling mechanism 1 is provided with a locking mechanism to lock the sand blowing plate onto the liftable sand filling mechanism. The locking mechanism consists of one or two threaded holes 11 located on the outside of the T-slot on the liftable sand filling mechanism (the threaded holes 11 are aligned with the width direction of the sand blowing plate) and a locking bolt 12 threadedly connected to the threaded holes. The inner end of the locking bolt abuts against the outer wall of the sand blowing plate in the width direction to secure the sand blowing plate onto the liftable sand filling mechanism. During use, the sand blowing plate 2 is mainly subjected to vertical force. The T-slot and the T-shaped cross-section of the sand blowing plate can support the sand blowing plate 2. The threaded holes 11 are aligned with the width direction of the sand blowing plate. The locking bolt 12 provides a force along the width direction of the sand blowing plate to achieve locking and prevent the sand blowing plate from moving in the length direction. This locking mechanism is simple and easy to use.

[0028] In addition, since the lifting sand filling mechanism 1 has a relatively large lifting space, the threaded hole 11 is located on the outside of the T-slot (the threaded hole 11 is consistent with the width direction of the sand blowing plate), which provides ample space for disassembly and assembly and facilitates operation.

[0029] The method of using the quick-release sand core blowing plate structure of this utility model is as follows: When it is necessary to replace the blowing plate on the lifting sand filling mechanism 1, one or two locking bolts 12 are removed, and then the blowing plate 2 is pushed along the T-slot to remove the blowing plate from the lifting sand filling mechanism. Then, another blowing plate adapted to the new sand core mold is replaced in the T-slot, and one or two locking bolts 12 are screwed back on to complete the replacement.

[0030] This utility model features a quick-release sand core blowing plate with a reasonable structural design, enabling convenient and quick replacement of the blowing plate.

[0031] The above description is only a preferred embodiment of this utility model. For those skilled in the art, designing different forms of a novel prefabricated steel plate composite shock-absorbing wall design method that considers multi-stage stress based on the teachings of this utility model does not require creative labor. All equivalent changes, modifications, substitutions and variations made in accordance with the scope of the patent application of this utility model without departing from the principles and spirit of this utility model shall be covered by this utility model.
