DETAILED DESCRIPTION​

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings of the present application. Obviously, the embodiments described in the present application are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] Referring to Figures 1 to 5 , the present application is further described as follows:

[0028] In combination with Figure 1 and Figure 5 , a sampling mold tool for sampling rubber or plastic products, comprising a bottom plate 1 and at least one cutter 2, the cutter 2 is arranged on the bottom plate 1 for cutting sampling of the sample 8; the cutter 2 is connected at the end to form a closed loop, the cutter 2 is in the shape of a sandglass with thick top and bottom and thin middle; in this embodiment, the cutter 2 is two, the number of cutters 2 can be increased or decreased as needed; the inside of the cutter 2 forms a sampling groove 20, the outside of the cutter 2 is provided with a support plate, the support plate 3 is detachably connected to the bottom plate 1, for supporting and protecting the cutter 2, to avoid deformation of the cutter; the cutter 2 extends through the support plate 3 to the side away from the bottom plate 1; the sampling groove 20 is provided with a top die assembly 4, which can move in the z-axis direction in the sampling groove 20 to eject the sample in the sampling groove 20; thereby avoiding the problem that the sample is difficult to take out after sampling is completed, improving the sampling efficiency, and avoiding the risk of cutting caused by accidental contact with the cutter 2.

[0029] In combination with Figure 3 , in this embodiment, the top die assembly 4 includes a push plate 41 and an adjusting component 42, the adjusting component 42 is used to limit the position of the push plate 41 in the sampling groove 20, to avoid the push plate 41 from falling out of the sampling groove 20; wherein the adjusting component 42 includes an adjusting rod and a locking nut, the push plate 41 is provided with a stepped hole 40, the locking nut is arranged in the stepped hole 40 to connect the adjusting rod, by adjusting the position of the locking nut on the adjusting rod, the position of the push plate 41 in the sampling groove 20 is controlled; a plurality of expansion components 43 are arranged between the bottom plate 1 and the push plate 41, the expansion components 43 are used to drive the push plate 41 to move in the z-axis direction, the expansion components 43 are compression springs; when sampling, the cutter 2 cuts the sample 8 to be sampled, the sample retained in the sampling groove 20 pushes the push plate 41 to compress the expansion components 43 Figure 3When the sampling is completed, the telescopic part 43 pushes the push plate 41 to reset and move out of the sampling groove 20 to push the sample out (the dotted line position of the push plate 41) Figure 3 In the non-working state, the push plate 41 protrudes from the cutter 2, thereby protecting the cutting edge of the cutter 2 from being deformed due to external impact.

[0030] In combination Figure 4 The support plate 3 is formed by stacking a plurality of adjusting plates 30, and the adjusting plates 30 are connected to the bottom plate 1 through connecting parts, which can be screws. By disassembling or replacing the adjusting plates 30 with different thicknesses, the length of the cutter 2 protruding out of the support plate 3 can be controlled to adapt to samples 8 with different thicknesses, thereby preventing the cutter 2 from being damaged due to excessive protrusion and providing support and protection for the cutter to improve the strength of the cutter itself.

[0031] In combination Figure 5 The support frame 5 is further provided with a pressure plate assembly 6 that can move reciprocally along the z-axis direction, and the pressure plate assembly 6 is used to drive the bottom plate 1 to move and cut the sample 8, thereby enabling one-time sampling, saving effort and being convenient to operate, and greatly reducing the working intensity of the operator. The pressure plate assembly 6 includes a driving part and a pressure plate 61, the driving part is used to drive the pressure plate 61 to move, and a pressure sensor is arranged between the pressure plate 61 and the driving part. When sampling, the pressure plate assembly is lifted upward when the pressure sensor reaches a set threshold value, thereby preventing the cutter from being damaged due to excessive pressure.
