[0060] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, an embodiment of the present invention provides a multi-process sample core making machine, including a frame 10, a sand shooting assembly 100, an air heating element 200, a blowing assembly 300, a clamping assembly 400 and a core box 500; the air heating element 200 is arranged on the top of the frame 10; the sand shooting assembly 100 is arranged in the frame 10, the blowing assembly 300 is movably arranged in the frame 10, the air inlet of the blowing assembly 300 is connected with the exhaust port of the air heating element 200, and the blowing assembly 300 is located below the sand shooting assembly 100; the clamping assembly 400 with a heating function is arranged in the frame 10, the clamping assembly 400 is located below the blowing assembly 300, and the two clamping members 420 of the clamping assembly 400 can move horizontally relative to the frame 10, and the left and right core boxes 500 of the core box 500 are respectively arranged on the two clamping members 420, so that the two clamping members 420 drive the left and right core boxes 500 of the core box 500 to close the film or open the mold.

[0061] Specifically, the components for realizing the heating function on the left and right halves of the core box 500 are arranged on the clamping assembly 400 , so as to reduce the weight of the core box 500 and facilitate the test personnel to disassemble the core box 500 .

[0062] Specifically, when producing samples, the test personnel remove the aluminum sand shooting tube 120 in the sand shooting assembly 100, and then load the mixed sand into the aluminum sand shooting tube. Generally, 1L of mixed sand is required, and the weight of the mixed sand is about 1.5 kg. Then the aluminum sand shooting tube 120 is put back, and then the core box 500 corresponding to the process is installed. Then the clamping assembly 400 molds the left and right core boxes 500, and then the sand shooting work is carried out. And it is decided whether to turn on the blowing assembly 300 according to the process requirements. The air heating component 200 can provide hot air for the blowing assembly 300, and then blow air into the core box 500 through the blowing assembly 300. In addition, it is decided whether to turn on the heating function of the clamping assembly 400 according to the process requirements.

[0063] See also Figure 1-Figure 10As shown, in the optional scheme of this embodiment, the core box 500 includes a bending core box 500 for producing a bending specimen, a compression core box 500 for producing a compression specimen, and a tensile core box 500 for producing a tensile specimen; the bending core box 500 includes a left bending core box 511, a right bending core box 512, and a bottom mold 513, the cavities on the left bending core box 511 and the right bending core box 512 are arranged in a triangle, the bottom mold 513 includes a horizontal slide rail 514, a horizontal telescopic rod 515, a lifting rod 516, a bottom film seat 517 and a bottom film 518, the horizontal slide rail 514 is arranged on the frame 10, the bottom film seat 517 is slidably arranged on the horizontal slide rail 514, one end of the horizontal telescopic rod 515 is slidably connected to the bottom film seat 517, and one end of the horizontal telescopic rod 515 is slidably connected to the bottom film seat 517. 17, and the other end is connected to the frame 10, the lifting rod 516 is arranged on the bottom film seat 517, and the bottom film 518 is arranged on the movable end of the lifting rod 516; the pressure-resistant core box 500 includes a left pressure-resistant core box 521 and a right pressure-resistant core box 522, and the tops of the left pressure-resistant core box 521 and the right pressure-resistant core box 522 are both provided with a detachable pressure plate 523, and the left pressure-resistant core box 521 is provided with a bottom plate 524, and the ground of the bottom plate 524 is provided with a demoulding spring, and the right pressure-resistant core box 522 is provided with a support block 525 for supporting the bottom plate 524; the tensile core box 500 includes a left tensile core box 531 and a right tensile core box 532, and the left tensile core box 531 and the right tensile core box 532 are provided with a detachable movable block 533.

[0064] Specifically, according to the national standard track, the core box 500 includes a bending core box 500 for producing bending specimens, a compression core box 500 for producing compression specimens, and a tensile core box 500 for producing tensile specimens. The three core boxes 500 can produce three specimens corresponding to the national standard.

[0065] Among them, the cavities on the left anti-bending core box 511 and the right anti-bending core box 512 are set to be triangular, that is, the left anti-bending core box 511 and the right anti-bending core box 512 can still produce rectangular specimens after being molded together. However, by setting the cavities on the left anti-bending core box 511 and the right anti-bending core box 512 to be triangular, the single-sided core box 500 is in contact with the specimen on only two sides, which is easier to demold than the three-side contact in the prior art, so that there is no need to set a demolding rod structure on the core box 500, further reducing the weight of the core box 500, so that the experimenter can carry it more conveniently.

[0066] When the bending-resistant core box 500 is producing a sample, the lifting rod 516 drives the bottom film 518 to rise, so that the bottom film 518 contacts the left bending-resistant core box 511 and the right bending-resistant core box 512 to form a completed core box 500. When demolding, the left bending-resistant core box 511 and the right bending-resistant core box 512 are driven by the clamping assembly 400 to move outward, and the sample stays on the bottom film 518. Then the lifting rod 516 drives the bottom film 518 to descend, and then the horizontal telescopic rod 515 drives the bottom film seat 517 to move on the horizontal slide rail 514, thereby moving the bottom film 518 outward so that the staff can take the bending-resistant sample.

[0067] Among them, the left compression core box 521 and the right compression core box 522 are provided with a detachable pressing plate 523 on the top of the left compression core box 521 and the right compression core box 522, a bottom plate 524 is provided in the left compression core box 521, a demoulding spring is provided on the ground of the bottom plate 524, and a support block 525 for supporting the bottom plate 524 is provided in the right compression core box 522. When demoulding, the tester first removes the pressing plate 523, and then the bottom plate 524 located at the bottom of the sample will move upward under the action of the demoulding spring, thereby completing the demoulding, so that there is no need to set a demoulding rod mechanism on the compression core box 500, thereby further reducing the weight of the core box 500, so that the tester can carry it. Among them, the pressing plate 523 on the left compression core box 521 and the right compression core box 522 is fixed by bolt connection. A support block 525 is provided in the right compression core box 522 to ensure the stability of the bottom plate 524 during core shooting and ensure the structure of the sample.

[0068] The tensile core box 500 includes a left tensile core box 531 and a right tensile core box 532, and a detachable movable block 533 is arranged in the left tensile core box 531 and the right tensile core box 532. Through the arrangement of the movable block 533, when demoulding, the bolts fixing the movable block can be unscrewed, and then the movable block 533 can be taken out, and finally only one side of the sample is in contact with the core box 500, and the staff can demould conveniently, so that the demoulding rod mechanism does not need to be arranged on the tensile core box 500, thereby further reducing the weight of the core box 500, so that the experimenter can carry it.

[0069] It should be noted that, through the configuration of the core box 500, the weight of the left and right halves of the core box 500 can be reduced from the traditional weight of about 20 kg to about 10 kg.

[0070] See also Figure 1-Figure 10As shown, in the optional scheme of this embodiment, the sand shooting assembly 100 includes a sand shooting lifting member 110, an aluminum sand shooting tube 120, a pressure head 130, a sand shooting mounting plate 140 and a sand shooting valve; the sand shooting lifting member 110 is arranged in the frame 10, the pressure head 130 is arranged on the top of the aluminum sand shooting tube 120, and the top of the pressure head 130 is connected to the movable end of the sand shooting lifting member 110; the sand shooting mounting plate 140 is detachably arranged at the sand outlet of the aluminum sand shooting tube 120, and the sand shooting valve is installed between the aluminum sand shooting tube 120 and the pressure head 130.

[0071] Before producing the sample, the experimenter needs to remove the aluminum sand-shooting tube 120 and the sand-shooting mounting plate 140 of the sand-shooting assembly 100 from the frame 10, and then install them back after filling them with mixed sand.

[0072] Specifically, during sand shooting, the sand shooting lifting component 110 drives the aluminum sand shooting cylinder 120, the pressure head 130, the sand shooting mounting plate 140 and the sand shooting valve to descend as a whole, and the air bag can supply air to the pressure head 130 and then inflate the aluminum sand shooting cylinder 120, and then the mixed sand is filled from the aluminum sand shooting cylinder 120 into the mold cavity of the core box 500.

[0073] Among them, the use of the aluminum sand-shooting tube 120 can reduce the overall weight of the sand-shooting assembly 100 from about 30 kg (filled with mixed sand) to 8-10 kg (filled with mixed sand).

[0074] See also Figure 1-Figure 10 As shown, in an optional solution of this embodiment, a heat insulation plate 160 is provided on the side of the sand blasting mounting plate 140 facing away from the aluminum sand blasting cylinder 120 .

[0075] Specifically, a heat insulation plate 160 is provided between the sand blasting mounting plate 140 and the aluminum sand blasting cylinder 120 to reduce the heat transfer from the core box 500 to the aluminum sand blasting cylinder 120, thereby eliminating the need to provide cooling pipelines on the sand blasting mounting plate 140 and the aluminum sand blasting cylinder 120, thereby further reducing the overall weight of the sand blasting assembly 100 for easier movement by experimenters.

[0076] See also Figure 1-Figure 10 As shown, in the optional scheme of this embodiment, the blowing assembly 300 includes a sliding mounting seat 310, a blowing driving air rod 320 and a blowing piece 330; a slide rail is arranged in the frame 10, the sliding mounting seat 310 is slidably arranged on the slide rail, the blowing driving air rod 320 is arranged on the frame 10, and the movable end of the blowing driving air rod 320 is connected to the sliding mounting seat 310; the blowing piece 330 is arranged on the sliding mounting seat 310, the air inlet of the blowing piece 330 is connected to the air heating piece 200, and the air outlet of the blowing piece 330 can be connected to the core box 500.

[0077] Specifically, before the sandblasting, the air-blowing driving air rod 320 drives the sliding mounting seat 310 to move, so that the air-blowing member 330 moves to the cavity feed port of the core box 500, so as to perform the air-blowing operation.

[0078] See also Figure 1-Figure 10 As shown, in the optional scheme of this embodiment, the blowing member 330 includes a blowing box 331 and a return spring 332; a hollow portion for installing the blowing box 331 is opened on the sliding mounting seat 310, a flange 333 is provided at the edge of the top plate of the blowing box 331, a butt column 334 is provided on the bottom surface of the flange 333, an end of the butt column 334 away from the flange 333 is butt-jointed with the sliding mounting seat 310, and the return spring 332 is sleeved on the butt column 334; the air inlet of the blowing box 331 is connected to the air heating element 200, and the air outlet of the blowing box 331 can be connected to the core box 500.

[0079] Specifically, when the blowing component 330 moves to the cavity feed port of the core box 500, the sand shooting lifting component 110 drives the sand shooting cylinder, the pressure head 130, the sand shooting mounting plate 140 and the sand shooting valve to descend, and the sand shooting mounting plate 140 and the sand shooting valve can be pressed on the blowing box 331. At this time, the return spring 332 is pressurized and the blowing box 331 can descend, so that the blowing box 331 is tightly in contact with the cavity feed port of the core box 500, and then the blowing work can be performed according to demand, and the blown hot air is provided for the air heating component 200.

[0081] Specifically, during the blowing process, according to process requirements, the valve between the triethylamine supply member 600 and the blowing box 331 may be opened so that the triethylamine can be blown into the core box 500 .

[0082] For example, when conducting a hot core process experiment, only the mold needs to be heated. When conducting a cold core process experiment, the sand blasting work is only performed by blowing triethylamine with hot air. When conducting an inorganic process experiment, the mold is heated and hot air is blown into the mold.
