[0046] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0047] like Figure 1-Figure 7 As shown, this embodiment provides a forming mold 001, which is used to make an asphalt mixture specimen. The forming mold 001 includes a bottom plate 1 and a side plate 2. Figure 2 As shown, a support plate groove 101 is provided on the lower surface of the bottom plate 1, and the support plate groove 101 extends to the edge of the lower surface of the bottom plate 1, and along the edge of the lower surface of the bottom plate 1 toward the inner side of the bottom plate 1, the width of the support plate groove 101 remains unchanged or gradually decreases. Figure 2 The support plate slot 101 is not visible from the perspective of Figure 2 In the figure, the support plate slot 101 is indicated by a dotted line. Figure 3 and Figure 4 As shown, a support plate 201 matching the support plate groove 101 is arranged on the side plate 2, and the support plate 201 is arranged on the first surface where the side plate 2 and the bottom plate 1 are attached. Figure 3 and Figure 4 The support plate slot 101 is not visible from the perspective of Figure 3 and Figure 4 In the figure, the support plate 201 is indicated by a dotted line.

[0048] By setting a pallet groove 101 extending to the edge of the lower surface of the bottom plate 1 on the lower surface of the bottom plate 1, the pallet 201 on the side plate 2 is pushed into the pallet groove 101 along the edge of the bottom plate 1 until the side of the side plate 2 and the bottom plate 1 are fitted together. At this time, the pallet 201 and the pallet groove 101 are matched, and the bottom plate 1 and the side plate 2 are fixed by the pallet 201 and the pallet groove 101. When the forming mold 001 is used to make asphalt mixture rutting plate specimens by wheel rolling method, after the fixing components between the side plates 2 are removed, the side plates 2 can be directly pulled outward to separate the side plates 2 from the bottom plate 1, and the bottom plate 1 and the specimen can always be placed stably on the ground, and the specimen can be demoulded without turning over the entire forming mold 001 and the specimen.

[0049] like Figure 2 As shown, in this embodiment, the bottom plate 1 of the molding die 001 is rectangular, and the side plate 2 of the molding die 001 includes a first side plate 21 and a second side plate 22 that are vertically connected to each other. Figure 1 , Figure 3 and Figure 4 As shown, the side plate 2 further includes a fixing assembly, which includes a first fixing portion 2021 disposed on the first side plate 21 and a second fixing portion 2022 disposed on the second side plate 22. The fixing assembly can be switched between a first position and a second position. Figure 5 As shown, when the fixing assembly is in the first position, the first fixing portion 2021 and the second fixing portion 2022 are separated, and the first side plate 21 and the second side plate 22 can be separated; Figure 1 , Figure 6 and Figure 7 As shown, when the first fixing portion 2021 of the fixing assembly is in the second position, the first fixing portion 2021 and the second fixing portion 2022 cooperate to lock the second side plate 22 and the second side plate 22. That is to say, when the first fixing portion 2021 of the fixing assembly is in the first position, the fixing assembly is in an unlocked state, and the first side plate 21 and the second side plate 22 can be separated. When the first fixing portion 2021 of the fixing assembly is in the second position, the fixing assembly is in a locked state, and the first side plate 21 and the second side plate 22 are connected and fixed and will not separate. By respectively arranging the first fixing portion 2021 and the second fixing portion 2022 on the first side plate 21 and the second side plate 22, the installation and removal of the side plate 2 are facilitated.

[0050] At the same time, if Figure 3 As shown, the end of the first side plate 21 has an embedding groove 211, as shown in FIG. Figure 4As shown, the end of the second side plate 22 has an embedding block 221 that matches the embedding groove 211. By having the matching embedding groove 211 and the embedding block 221 on the first side plate 21 and the second side plate 22, the connection between the first side plate 21 and the second side plate 22 is more stable. In other words, in addition to being fixed by the fixing assembly, the first side plate 21 and the second side plate 22 also have the matching embedding groove 211 and the embedding block 221, and the embedding block 221 can be embedded in the embedding groove 211 to achieve the preliminary connection and fixation between the first side plate 21 and the second side plate 22.

[0051] When assembling the molding mold, the fixing component is first in the first position, and the embedding block 221 is embedded in the embedding groove 211 to achieve preliminary fixation of the first side panel 21 and the second side panel 22, and then the fixing component is switched to the second position to firmly lock the first side panel 21 and the second side panel 22 to prevent the first side panel 21 and the second side panel 22 from separating during the process of making the specimen.

[0052] In this embodiment, if Figure 1 and Figure 3 As shown, the first fixing portion 2021 is a spring buckle arranged beside the embedding groove 211. Figure 4 As shown, the second fixing portion 2022 is a fixing groove provided on the embedded block 221, and the spring buckle can be inserted into the fixing groove to lock the first side plate 21 and the second side plate 22. Specifically, as Figure 1 As shown, the length of the embedded block 221 is greater than the depth of the embedded groove 211. Therefore, after the embedded block 221 is embedded in the embedded groove 211, the embedded block 221 protrudes relative to the first side plate 21, and the second fixing portion 2022, i.e., the fixing groove, is provided at the protruding portion of the embedded block 221 so as to be engaged with the first fixing portion 2021, i.e., the spring. Figure 5 As shown, the spring buckle has a handle and a locking ring. When the handle is lifted, the locking ring is in the first position, that is, outside the fixing groove. At this time, the locking ring does not affect the matching or disassembly of the embedded block 221 and the embedded groove 211. When the handle is pressed, Figure 6 and Figure 7 As shown, the locking ring switches to the second position, that is, enters the fixing groove, thereby firmly locking the first side plate 21 and the second side plate 22. By respectively configuring the first fixing portion 2021 and the second fixing portion 2022 as a spring buckle and a fixing groove, the fixing assembly has a simple structure and is easy to operate.

[0053] Of course, in other embodiments, the fixing assembly may also be other fixing devices that are convenient for locking and unlocking, which will not be described in detail here.

[0054] In this embodiment, the forming template is used for the production of asphalt mixture specimens formed by the wheel rolling method. The first side plate 21 is parallel to the rolling direction, and the second side plate 22 is perpendicular to the rolling direction. There are two first side plates 21 and two second side plates 22. Both ends of each first side plate 21 have an embedding groove 211, and both ends of each second side plate 22 have an embedding block 221. That is to say, each forming mold 001 has 4 groups of embedding grooves 211 and embedding blocks 221, and correspondingly has 4 groups of fixed components.

[0055] like Figure 2 As shown, in this embodiment, along the edge of the lower surface of the bottom plate 1 toward the inner side of the bottom plate 1, the width of the support plate groove 101 remains unchanged, specifically, the support plate groove 101 is a rectangular groove. By setting the support plate groove 101 as a rectangular groove, processing is convenient.

[0056] Of course, in other embodiments, the width of the support plate slot 101 may be gradually reduced along the edge of the lower surface of the base plate 1 toward the inner side of the base plate 1 , so that the support plate 201 can be detachably embedded in the support plate slot 101 .

[0057] like Figure 1 and Figure 4 As shown, in this embodiment, a pull ring 203 is provided on the second surface of the side plate 2 opposite to the first surface, that is, a pull ring 203 is provided on the second surface of the side plate 2, i.e., the outer surface of the molding die 001, and in this embodiment, since spring buckles are provided on the two first side plates 21, it is inconvenient to provide the pull ring 203, and the pull ring 203 is only provided on the two second side plates 22. By providing the pull ring 203 on the second surface of the second side plate 22, it is more convenient to move the molding die 001 or disassemble the side plate 2.

[0058] Of course, in other embodiments, if the molding mold 001 is relatively large and the first side plate 21 has enough space to set the pull ring 203 in addition to the spring buckle, the pull ring 203 may also be set on the first side plate 21.

[0059] In this embodiment, the lower surface of the support plate 201 is flush with the lower surface of the side plate 2, and the thickness of the support plate 201 is equal to the height of the support plate slot 101. By setting the lower surface of the support plate 201 to be flush with the lower surface of the side plate 2, and the thickness of the support plate 201 is equal to the height of the support plate slot 101, after the support plate 201 is embedded in the support plate slot 101, the lower surfaces of the support plate 201, the side plate 2 and the bottom plate 1 form a completely flush plane, which can improve the load-bearing capacity of the molding mold 001 and make the molding mold 001 more beautiful.

[0060] Of course, in other embodiments, as long as the thickness of the bottom plate 1 is sufficient, the support plate 201 and the side plate 2 may protrude relative to the lower surface of the bottom plate 1, which will not affect the molding of the test piece. Specifically, the thickness of the bottom plate 1 should be greater than or equal to 3 mm, and the thickness of the bottom plate 1 mentioned here refers to the thickness of the thinnest part of the bottom plate 1.

[0061] The bottom plate 1 in this embodiment is a rectangular plate with a support plate groove 101 formed on it. Therefore, the thickness of the bottom plate 1 in this embodiment refers to the thickness of the bottom plate 1 at the support plate groove 101. In this embodiment, the thickness is 5 mm. At the same time, the thickness of the support plate 201 in this embodiment is also 5 mm, that is, after the entire molding die 001 is installed, the overall thickness of the bottom plate 1 is 10 mm.

[0062] Of course, in other embodiments, according to different needs, the thickness of the base plate 1 can be greater than or equal to 3 mm to meet the strength requirements, especially if the material of the forming mold 001 is a high-strength steel plate, then the thickness of the steel plate is greater than or equal to 3 mm, which can meet the production requirements of most specimens.

[0063] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
