[0022] The following are specific embodiments of the utility model and the accompanying drawings to further describe the technical solution of the utility model, but the utility model is not limited to these embodiments.

[0023] Example 1

[0024] like Figure 1-Figure 2 As shown, the anti-interference magnetic core sintering support plate includes a support plate body 1, characterized in that a plurality of supporting protrusions 2 are arranged on the plate surface of the support plate body 1, a plurality of air flow holes 3 penetrating the support plate body 1 are opened between the supporting protrusions 2, and an air flow cavity 11 is opened on the plate surface of the support plate body 1 on one side relative to the supporting protrusions 2, and the air flow cavity 11 is connected to the air flow holes 3.

[0025] That is, a plurality of supporting protrusions 2 are arranged on the placing surface at the upper end of the pallet body 1, which are used to lift up the material tray of the magnetic core and the pallet body 1 in the air, so that there is space for air flow between the material tray and the pallet body 1, so that the hot air flow can evenly pass through the bottom of the material tray to ensure that the magnetic core has a balanced heating environment, and reduce the contact area between the pallet body 1 and the material tray, thereby reducing the temperature change caused by the contact.

[0026] In this embodiment, the supporting protrusions 2 are evenly distributed on the plate surface of the support plate body 1 , and each air flow hole 3 maintains the same distance from each adjacent supporting protrusion 2 .

[0027] The evenly distributed support protrusions 2 can stably support the material and reduce the contact area between the material and the support plate body 1, thereby reducing the temperature effect of the support plate body 1 on the material. The air flow holes 3 are arranged at equal intervals around the adjacent support protrusions 2, so that the hot air flow can fully transfer the heat to the surface of the material instead of being blocked by the support protrusions 2.

[0028] In this embodiment, the support protrusion 2 is in a truncated cone shape, the larger bottom surface of which is connected to the plate surface of the support plate body 1, and the circular edges of the smaller bottom surface of the support protrusion 2 are provided with rounded corners.

[0029] The area of ​​the contact end of the support protrusion 2 is reduced to reduce the contact between the support plate and the material, thereby reducing the temperature change difference. The circular edges of the contact end are rounded to prevent the edges from scratching the material and reducing the quality of the finished product.

[0030] In this embodiment, an air flow passage separated by a plurality of supporting protrusions 2 is provided on the plate surface of the support plate body 1 , and the air flow passage is connected with the air flow holes 3 .

[0031] After the supporting protrusion 2 lifts up the material, a space for air flow is formed between the two, so that the hot air flowing out of the air flow hole 3 fills the air flow path and heats the lower end of the material.

[0032] In this embodiment, a support member is provided on one side of the airflow cavity 11 of the support plate body 1 , and the airflow cavity 11 is divided by the support member.

[0033] Due to the opening of the airflow cavity 11, the plate surface area of ​​the pallet body 1 is suspended in the air and lacks supporting strength. Especially after loading materials, the plate surface area corresponding to the airflow cavity 11 is prone to concave deformation. Therefore, support members are arranged at the position lacking support to strengthen the plate surface's supporting ability to heavy objects.

[0034] Preferably, the support member includes a peripheral support leg 41 and a central support leg 42 . The central support leg 42 is arranged away from the air flow hole 3 , and the peripheral support leg 41 is arranged along the edge of the support plate body 1 .

[0035] The edge support legs 41 are arranged along the edge of the lower end surface of the support plate. When the annular edge is placed on the transport track, an internal airflow cavity 11 is formed. The suspended board surface bearing area is then strengthened by the arrangement of the central support legs 42.

[0036] The central support leg 42 is not connected to the peripheral support leg 41 , so as to prevent the airflow cavity 11 from forming a plurality of independent spaces that hinder the blending of airflow.

[0037] Preferably, the airflow cavity 11 is surrounded by the peripheral support legs 41 , and a ventilation gap 43 is provided on the peripheral support legs 41 to allow the airflow cavity 11 to circumferentially circulate with the outside.

[0038] The placement surface of the transport track may not have gaps for airflow to pass through, so a plurality of ventilation gaps 43 are provided on the surrounding support legs 41 for lateral circulation.

[0039] Usually, the support plate body 1 is rectangular, the edge legs 41 are set along the length and width, and the ventilation gap 43 is opened in the middle of each length and width to avoid opening the ventilation gap 43 at the corner to avoid damaging the supporting stability of the edge legs 41.

[0040] In this embodiment, an expanded annular groove 31 is provided at the opening of the air flow hole 3 .

[0041] That is, the aperture of the air flow hole 3 is enlarged so that the air flow can enter the air flow passage more slowly and conduct heat evenly. In particular, when preventing the temperature difference between the air flow cavity 11 and the air flow passage, the air flow enters the air flow passage from the air flow hole 3 more quickly, and the air flow will more concentratedly dissipate heat to the material position facing the air flow hole 3, thereby causing the problem of increasing temperature difference.

[0042] Example 2

[0043] On the basis of Example 1, the support member setting mode on one side of the airflow cavity 11 is changed, and the support member includes a plurality of support protrusions 2, and the support protrusions 2 are arranged on the side of the support plate body 1 containing the airflow cavity 11, and are distributed correspondingly to the support protrusions 2 arranged on the opposite side of the support plate body 1.

[0044] That is, the support protrusion 2 which is the same as the loading surface of the pallet body 1 is used as the support structure of the lower end. The upper and lower ends of the plate surface can both have space for air flow to move for heat conduction, and the setting position is also the same as the upper end surface, which can avoid the concave and convex deformation of the plate surface to the greatest extent.

[0045] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
