Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically a batch indicator device for casting production. Background Technology

[0002] To ensure traceability of castings after delivery to customers, a production date number is typically left on the casting surface. However, with the investment in automated equipment, daily casting output has increased dramatically, potentially producing thousands of products in a single day. If a quality issue arises during customer use, the entire batch of castings faces the risk of return. If the casting includes a heat number and ladle number, the risk of return is reduced to the specific heat or ladle within the batch. Furthermore, the casting manufacturer can trace the on-site production conditions of that batch of castings based on the heat and ladle number. Therefore, leaving heat and ladle numbers on castings is particularly important. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model provides a casting production batch indication device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A batch indicator device for casting production includes a batch indicator disc, which comprises a disc body and a pointer, the pointer being an elastic element; a ring platform is provided on the upper end face of the disc body, and an indicator block is provided on the ring platform; a central shaft is connected to the center of the ring platform on the upper end face of the disc body, and a positioning cap is provided on the upper end of the central shaft; the pointer is provided with an adjustment groove, and symmetrical inner protrusions are provided in the adjustment groove near the pointer tip; the opening of the adjustment groove is larger than the outer diameter of the positioning cap, and the spacing between the symmetrical inner protrusions is smaller than the outer diameter of the positioning cap, the inner protrusions being located between the positioning cap and the disc body; a support sleeve is provided between the positioning cap and the disc body, and the upper end face of the ring platform is higher than the upper end face of the support sleeve; when the positioning cap is moved to the end near the pointer tip in the adjustment groove, the tail end of the pointer is locked in place on the ring platform, and the positioning cap, inner protrusions, and support sleeve are tightened under the elastic stress of the pointer.

[0006] Furthermore, the central shaft is plugged into the disk body.

[0007] Furthermore, the lower end face of the inner protrusion is flush with the lower end face of the pointer, and an accommodating distance is provided between the upper end face of the inner protrusion and the upper end face of the pointer, the accommodating distance being greater than the thickness of the positioning cap.

[0008] Furthermore, the indicator block is connected to the disk body by a stud, and the upper surface of the indicator block is higher than the upper surface of the pointer.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The utility model uses a pointer to conveniently indicate which batch and which lot of the casting came from by embedding it on the pattern, thus achieving traceability. The pointer can be readjusted after purging, and can be replaced when it becomes fatigued. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 4 The present invention provides a batch indicator device for casting production, including a batch number indicator panel, which includes a furnace batch number indicator panel 5 and a ladle batch number indicator panel 6.

[0018] The number indicator dial includes a dial body 7 and a pointer 2. A ring platform 71 is provided on the upper surface of the dial body 7, and an indicator block 4 is provided on the ring platform 71. A central shaft 72 is connected to the center of the ring platform 71 on the upper surface of the dial body 7. A positioning cap 74 is provided on the upper end of the central shaft 72. The pointer 2 is provided with an adjustment groove 3. A symmetrical inner protrusion 31 is provided at one end of the adjustment groove 3 near the needle tip of the pointer 2. The opening of the adjustment groove 3 is larger than the outer diameter of the positioning cap 74, and the spacing between the symmetrical inner protrusions 31 is smaller than the outer diameter of the positioning cap 74. The inner protrusions 31 are located between the positioning cap 74 and the dial body 7. A support sleeve 73 is provided between the positioning cap 74 and the dial body 7. The upper surface of the ring platform 71 is higher than the upper surface of the support sleeve 73. When the positioning cap 74 is moved to the end of the adjustment groove 3 near the needle tip of the pointer 2, the tail end of the pointer 2 is locked in place on the ring platform 71. Under the elastic stress of the pointer 2, the positioning cap 74, the inner protrusions 31, and the support sleeve 73 are fastened.

[0019] The central shaft 72 and the disc body 7 are connected by casting glue, interference fit, and step positioning.

[0020] The portion of the adjusting groove 3 without the inner protrusion 31 is used to pass through the positioning cap 74.

[0021] The lower end face of the inner protrusion 31 is flush with the lower end face of the pointer 2, and an accommodating distance is provided between the upper end face of the inner protrusion 31 and the upper end face of the pointer 2. The accommodating distance is greater than the thickness of the positioning cap 74 to avoid side collision with the positioning cap 74 during transportation, which would affect the central axis 72.

[0022] Nine indicator blocks 4 are provided, corresponding to numbers 1 to 9, and are arranged at 36° intervals. The indicator blocks 4 are connected to the disc body 7 by studs and casting adhesive. The upper surface of the indicator blocks 4 is higher than the upper surface of the pointer 2 to avoid side collision with the pointer 2 during transportation.

[0023] Specifically, the entire indicator dial is made of metal, and the pointer 2 is preferably made of spring steel.

[0024] Preferably, the casting adhesive used in this embodiment can be WD118, which has a temperature resistance of up to 200°C.

[0025] During the casting process, the nine indicator blocks 4 of the sequence number indicator disk represent 1-9 counterclockwise. By rotating the pointer 2 of the furnace sequence number indicator disk 5 counterclockwise, the furnace sequence number 1-9 is read. Then, the pointer 2 of the package sequence number indicator disk 6 is rotated counterclockwise to read the package sequence number 1-9. After rotating the pointer 2, the tail end of the pointer 2 is moved towards the ring platform 71, so that the pointer 2 bends and gets stuck on the ring platform 71, thus completing the fixation of the pointer 2.

[0026] Embed the furnace number indicator 5 and the batch number indicator 6 next to the production date number 1 of the pattern. The production date number 1 is a raised number plate that needs to be changed every day. Figure 3 The number in the middle represents the first package of the first furnace on March 22, 2022.

[0027] Use a pattern with furnace number indicator 5, ladle number indicator 6, and production date number 1 to mold sand cores. Castings produced using this sand core will have furnace number, ladle number, and production date number.

[0028] The application of the sequential indicator dial allows for more detailed recording of which day, furnace, and batch of the casting was produced, thus achieving precise traceability. After use, the sequential indicator dial can be adjusted by purging with high-pressure air and put back into use. If pointer 2 becomes fatigued and cannot be fixed, pointer 2 can be replaced.
