[0031] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0032] It should be noted that: unless otherwise defined, the technical terms or scientific terms used in this article should be understood by people with ordinary skills in the field to which the utility model belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of this utility model do not express quantitative restrictions, but indicate the existence of at least one; the "first", "second" and "third" used in this article should not be regarded as restrictions on the order of components, but are only used to distinguish different components; "include" or "comprise" and other similar words indicate that the elements or objects appearing before "include" or "comprise" include the elements or objects listed after "include" or "comprise" and their equivalents, but do not exclude other elements or objects with the same function.

[0033] In order to more clearly describe the specific structural composition of the combined shelf for the mold, Figure 1-6 Describe this embodiment:

[0034] like Figure 1 or Figure 2 As shown, a combined shelf for a mold includes a frame and at least two shelf groups mounted on the frame, and adopts a combined structure of a frame and multiple shelfs spliced ​​together, which is low in cost and easy to use;

[0035] A single shelf group is composed of shelf plates 1 that are abutted without gaps along their width direction. In the same shelf group, two adjacent shelf plates 1 have a first joint 101 when abutting each other. The first joint 101 has at least one bend in the cross section. The first joint 101 has a bend, which, on the one hand, allows adjacent shelf plates 1 to overlap when abutting each other, and avoids the generation of a large gap as much as possible; on the other hand, it can reduce the heat passing through the first gap 101, which is beneficial to reducing the heat loss of the mold.

[0036] Two adjacent shelf panels are butted against each other without gap along the length direction of the shelf panels 1, and a second joint 102 is formed when the two adjacent shelf panels are butted against each other; the frame is composed of longitudinal beams 2 and cross beams 3, and when the two adjacent shelf panels are butted against each other, one of the cross beams 3 (i.e., the compression beam 303) of the frame is pressed against the second joint 102. The second joint 102 is shielded by the compression beam 303 in the cross beam 3, which can also reduce heat loss.

[0037] After the first joint 101 and the second joint 102 are processed respectively, it can be ensured that there is still a small gap when multiple pieces or groups of shelf boards are spliced ​​together.

[0038] In this embodiment, the frame includes a longitudinal beam 2 and a transverse beam 3, and the transverse beam 3 is arranged on the surface of the longitudinal beam 2 in a direction perpendicular to the longitudinal beam 2; a pin hole 4 is provided at the intersection node of the longitudinal beam 2 and the transverse beam 3, so that the two are connected through a fastener 5 in the pin hole 4. The frame supports the shelf, reduces the instability factor of the shelf directly on the roller table, reduces torsion and misalignment, etc., and the frame structure is easy to process and has low cost.

[0039] The longitudinal beam 2 and the cross beam 3 can be made of silicon carbide or alumina ceramics, and the fastener 5 is made of ceramics or heat-resistant steel.

[0040] Specifically, Figure 2 As shown, the cross beam 3 at least includes mutually parallel side beams I 301, II 302 and a compression beam 303, and the compression beam 303 is located between the side beams I 301 and II 302. The side beams I 301 and II 302 cooperate with the longitudinal beams 2 to form a frame, and the compression beam 303 is used to press the second joint 102 when two shelf panels are abutted.

[0041] In order to ensure the stability of the above frame structure, it also includes a reinforcement beam 6 connected to the longitudinal beam 2 through a fastener 5, and the reinforcement beam 6 is not parallel to the side beam I301, so that the cross beam 3 and the longitudinal beam 2 form a trapezoidal and other stable structures.

[0042] In this embodiment, two adjacent shelf boards 1 in a single shelf board group have a first joint 101 when they are abutted. The following is a detailed description of the arrangement of the first joint 101:

[0043] Figure 5 , Figure 6 Two shapes of the first seam 101 are shown, Figure 6 The first joint shown in the figure makes the shapes of the two sides of the shelf 1 not centrally symmetrical;

[0044] See also Figure 5 , both side edges of the shelf 1 on the width are provided with protrusions 103, and in the same shelf group, the protrusions 103 of two adjacent shelfs 1 are staggered and abutted to form the first joint 101 with at least one bend;

[0045] at the same time, Figure 5 The figure shows that the two sides of the shelf are centrally symmetrical. Specifically, the protrusions 103 on the two width sides of the same shelf 1 are centrally symmetrical along the central axis of the shelf 1. This centrally symmetrical shape is easier to process.

[0046] In order to reduce the weight of the entire template and facilitate movement, a weight reduction cavity 104 is provided in the shelf 1.

[0047] The parts not described in detail in this embodiment are prior art.

[0048] It should be noted that although the utility model is described through the above embodiments, the utility model can also have other multiple embodiments. Without departing from the spirit and scope of the utility model, it is obvious that those skilled in the art can make various corresponding changes and deformations to the utility model, but these changes and deformations should all fall within the scope of protection of the attached claims of the utility model and their equivalents.
