Inorganic sand core profiling storage tray

Abstract

This utility model relates to a contoured storage tray for inorganic sand cores, comprising a base plate with six rigid limiting frames mounted on the upper part of the base plate, arranged in two rows. Each rigid limiting frame has a sponge pad installed inside its upper part. Four of the sponge pads located at the corners have at least one contoured clearance at their upper ends. Inside each rigid limiting frame, below the sponge pad, is a sliding push plate. An adjusting bolt is screwed onto the bottom of the base plate below each push plate, arranged vertically, with its upper end pressing against the push plate. This utility model uses multiple rigid limiting frames and sponge pads to achieve separate support. The design of the vertically adjustable push plates supports the bottom of the sponge pads to compensate for the height differences of the inorganic sand cores at their robust support points, ensuring minimal stress on the smaller, more vulnerable parts. Compared to ordinary flat sponge pads, the contoured sand core tray effectively solves the defects of complex inorganic sand cores such as easy breakage, reducing the core breakage rate of complex inorganic sand cores.

Description

Technical Field

[0001] This utility model relates to the field of inorganic sand core manufacturing technology, and in particular to an inorganic sand core conformal storage tray. Background Technology

[0002] In traditional inorganic sand core storage, the inorganic sand cores are placed on a large, flat sponge pad during surface treatment. This can easily cause stress concentration in small, protruding areas, leading to core breakage and cracking, thus failing to meet usage requirements. To solve this problem, a contoured storage tray for inorganic sand cores needs to be designed to change the stress distribution in small areas, prevent stress concentration, and thereby reduce the core breakage rate. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an inorganic sand core conformal storage tray, which uses multiple rigid limiting frames and sponge pads to achieve split support; the bottom of the adjustable push plate supports the sponge pad to compensate for the thick support points of the inorganic sand core with height differences, so as to ensure that the small and fragile parts are subjected to minimal force.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an inorganic sand core contour storage tray is provided, including a base plate. Six rigid limiting frames are installed on the upper part of the base plate. The six rigid limiting frames are arranged in two rows. A sponge pad is installed inside the upper part of each rigid limiting frame. At least one contour clearance is opened at the upper end of the four sponge pads located at the corners. A sliding push plate is installed inside the rigid limiting frame below the sponge pad. An adjusting bolt is screwed to the bottom of the base plate below each push plate. The adjusting bolt is arranged vertically, and the upper end of the adjusting bolt abuts against the middle of the lower end of the push plate.

[0005] As a supplement to the technical solution described in this utility model, a QR code label is provided on one side of the upper end of the base plate. The QR code label is engraved with the tooling number QR code and is used to cooperate with the automatic line data entry and traceability system.

[0006] As a supplement to the technical solution described in this utility model, a vertical sliding groove is provided on both sides of the inner wall of the rigid limiting frame, and sliders that cooperate with the vertical sliding groove are provided on both sides of the push plate.

[0007] As a supplement to the technical solution described in this utility model, a foot is installed at each of the four corners of the lower end of the base plate.

[0008] As a supplement to the technical solution described in this utility model, the rigid limiting frame is made of rigid wood or rigid metal and has an overall rectangular frame structure.

[0009] Beneficial Effects: This utility model relates to a contoured storage tray for inorganic sand cores, employing multiple rigid limiting frames and sponge pads to achieve separate support. An adjustable push plate is designed to support the bottom of the sponge pad, compensating for the uneven support points of the inorganic sand cores and minimizing stress on the smaller, more vulnerable areas. Compared to ordinary flat sponge pads, this contoured sand core tray effectively solves the defects of complex inorganic sand cores, such as easy breakage, and reduces the core breakage rate.

[0015] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0016] The embodiments of this utility model relate to an inorganic sand core contour storage tray, such as... Figure 1-4 As shown, the system includes a base plate 6. Six rigid limiting frames 1 are installed on the upper end of the base plate 6. The six rigid limiting frames 1 are arranged in two rows. A sponge pad 2 is installed inside the upper part of each rigid limiting frame 1. The upper part of the sponge pad 2 extends out of the rigid limiting frame 1. At least one contoured clearance 5 is opened at the upper end of the four sponge pads 2 located at the corners. A sliding push plate 8 is installed inside the rigid limiting frame 1 below the sponge pad 2. An adjusting bolt 11 is screwed to the bottom of the base plate 6 below each push plate 8. The adjusting bolt 11 is arranged vertically, and the upper end of the adjusting bolt 11 abuts against the middle of the lower end of the push plate 8.

[0017] The rigid limiting frame 1 is made of rigid wood or rigid metal, and has an overall rectangular frame structure. The rigid limiting frame 1 has a hollow internal space for mounting the sponge pads 2. The upper part of the sponge pads 2 provides elastic support for the sand core. The four corner sponge pads 2 have contoured clearances 5 at their upper ends. Figure 4 As shown, the inorganic sand core 3 has multiple protruding parts 12. The contoured clearance 5 is used to install and place the protruding parts 12, so that the protruding parts 12 are cleared to prevent the protruding parts 12 from supporting the sand core and causing the support point to become smaller. The lower part of the sponge pad 2 is surrounded by a rigid limiting frame 1 for limiting and supporting.

[0018] This invention employs multiple rigid limiting frames 1 and sponge pads 2 to achieve separate support. An adjustable push plate 8 is designed to support the bottom of the sponge pad 2, compensating for the uneven support points of the inorganic sand core and ensuring minimal stress on its delicate and vulnerable areas. Compared to ordinary flat sponge pads, the contoured sand core tray effectively solves the defects of complex inorganic sand cores, such as easy breakage, and reduces the core breakage rate of complex inorganic sand cores.

[0019] In practical applications, such as Figure 3 As shown, the inorganic sand core 3 is placed on a contoured storage tray, and the sponge pad 2 deforms to fit the surface of the sand core. During storage, the rigid limiting frame 1 and the sponge pad 2 support the stress concentration points and support points of the sand core, changing the stress position and uniformly distributing stress to reduce core breakage.

[0020] A QR code label 4 is provided on one side of the upper end of the base plate 6. The QR code label 4 is engraved with the tooling number QR code and is used to cooperate with the automatic line data entry and traceability system.

[0021] The rigid limiting frame 1 has a vertical sliding groove 9 on each of its two inner walls. The push plate 8 has sliders 10 on both sides that cooperate with the vertical sliding groove 9. The vertical sliding groove 9 and the sliders 10 cooperate to ensure the stability of the push plate 8 sliding up and down. The vertical sliding groove 9 can adopt a dovetail groove, T-groove or other structure, and the shape of the sliders 10 can be matched with the vertical sliding groove 9.

[0022] A foot 7 is installed at each of the four corners of the bottom of the base plate 6. The four feet 7 are used to raise the base plate 6 and leave a certain amount of operating space under the base plate 6.

[0023] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0024] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0025] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0026] The above provides a detailed description of an inorganic sand core contour storage tray provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
