The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0030] Example

[0031] Please refer to Figures 1 to 6 The present embodiment provides a casting mechanism for a special-shaped mold, including a mold, wherein a casting cavity 10 is provided in the mold, wherein the casting cavity 10 is a special-shaped surface layered structure with thickness, and the casting cavity 10 is inclined; secondly, it includes a casting tube 20, wherein the casting tube 20 is detachably and slidably inserted into the casting cavity 10, and the casting end of the casting tube 20 is located at the bottom of the casting cavity 10; thirdly, it includes a plurality of cylindrical and elastic net bags 31, wherein the net bags 31 are slidably sleeved on longitudinal steel bars 32, wherein the longitudinal steel bars 32 are longitudinally arranged in the casting cavity 10, wherein the top end of the net bag 31 is connected to the top end of the longitudinal steel bars 32, and the bottom end of the net bag 31 is sealed; fourthly, it includes a plurality of vibrating rods 30, wherein the vibrating rods 30 correspond to the net bags 31 one by one, and the vibrating rods 30 are slidably penetrated into the corresponding net bags 31.

[0032] The pouring mechanism for special-shaped molds provided in this embodiment, by setting up a mold as the pouring basis of the special-shaped surface structure, is convenient for the subsequent insertion and removal of the pouring tube 20 and the sliding in and out of the vibrating rod 30, as well as the subsequent discharge of bubbles by setting the mold as inclined. On this basis, by setting the pouring tube 20, it can be detachably and slidably inserted in the pouring cavity 10, so that its pouring end can extend into the bottom of the pouring cavity 10, and pouring starts from the bottom of the pouring cavity 10, and the air is gradually discharged upward by utilizing the property that the density of cement is greater than that of air. Since the two slide together, the pouring tube 20 can be gradually pulled up during the pouring process, thereby avoiding the pouring tube 20 from being subjected to too much external pressure, resulting in pouring difficulties, and also avoiding the holes generated when the pouring tube 20 is pulled out at the end of a one-time pouring to draw in air. On this basis, by setting a cylindrical and elastic net bag 31, a semi-closed slideway structure is formed, and the net bag 31 is penetrated by longitudinal steel bars 32 to limit its direction and movement direction, and Its lateral movement is limited so that the net bag 31 can be pulled upward along the longitudinal steel bar 32; on this basis, by setting the vibrating rod 30, when in use, it is first made to slide to the bottom of the casting cavity 10 through the corresponding net bag 31 regulation, and the cement poured at the bottom is continuously vibrated to discharge the bubbles in time, and then the casting tube 20 is gradually pulled up, and the net bag 31 is pulled up at the same time, and the vibrating rod 30 in it is pulled up by the net bag 31, so that the vibrating rod 30 can cooperate with the pulling up of the casting tube 20 to vibrate and exhaust the newly poured cement, and enable it to withdraw from the cement poured in the upper layer in time, so as to avoid the formation of a large cavity and the introduction of air when it is pulled out at the end. During the pulling process, due to the mesh semi-closed structure of the net bag 31, the cement in it can flow out smoothly without being entrained by the cement; through the mutual cooperation of the above-mentioned features, the casting mechanism for special-shaped molds can effectively solve the problem that the existing special-shaped surface molds cannot effectively handle bubbles during the casting process.

[0033] In order to make the vibration rod 30 slide down the net bag 31 more smoothly, the side wall of the vibration rod 30 is a smooth conical surface.

[0034] In order to further enable the vibration rod 30 to slide down the net bag 31 more smoothly, the diameter of the bottom end of the vibration rod 30 is less than the diameter of the top end, and the end faces of both ends of the vibration rod 30 are both convex arc surfaces with smooth transition.

[0035] In order to further explain the specific structure of the mold, the mold includes a back mold plate 11, a side mold plate 12 and a front mold plate 13. The back mold plate 11 and the front mold plate 13 are matching special-shaped surface plates. The back mold plate 11 is arranged in parallel with the front mold plate 13 to form a casting interlayer. The side mold plate 12 is arranged around the casting interlayer so that the casting interlayer is enclosed as the casting cavity 10.

[0036] In order to prevent unnecessary relative sliding between the back template 11 and the front template 13 , a plurality of positioning anchor rods 50 are vertically provided between the back template 11 and the front template 13 .

[0037] In order to accurately position the distance between the front template 13 and the back template 11, support members 51 are respectively provided at both ends of the positioning anchor rod 50 located in the casting cavity 10, and the end faces of the support members 51 abut against the back template 11 or the front template 13 to limit the distance between the back template 11 and the front template 13; locking nuts 52 are respectively screwed on the two ends of the positioning anchor rod 50 located outside the casting cavity 10, so that the back template 11 and the front template 13 are respectively clamped between the corresponding support members 51 and the locking nuts 52.

[0038] Preferably, the positioning anchor rods 50 are arranged in multiple rows, and a net bag 31 is provided between two adjacent rows of the positioning anchor rods 50; the casting pipe 20 is longitudinally passed through the center line of the casting cavity 10, and all the positioning anchor rods 50 and all the net bags 31 are symmetrically arranged with the casting pipe 20 as the axis.

[0039] In order to enable the support member 51 to be removed after the mold is removed, the support member 51 is in a truncated cone shape, and the large-diameter end of the support member 51 abuts against the back mold plate 11 or the front mold plate 13 .

[0040] Since the positioning anchor rod 50 is generally a metal rod, when the mold is removed, its end will be flush with the surface of the hyperbolic monomer. After subsequent painting, its end will cause the painted surface to turn red due to rust, seriously affecting the aesthetics. In order to solve the above problem, the positioning anchor rod 50 includes an embedded rod 501 and two sections of disassembly rod 502, and the two ends of the embedded rod 501 are respectively screwed to the two support members 51, and the two sections of the disassembly rod 502 are respectively screwed to the side of the two support members 51 away from the embedded rod 501, and the two locking nuts 52 are respectively screwed to the two sections of the disassembly rod 502; the support member 51, the embedded rod 501 and the disassembly rod 502 are coaxially arranged.

[0041] Through the above arrangement, when disassembling the mold, the locking nut 52, the disassembly rod 502, and the mold are disassembled in sequence, and then the support member 51 is unscrewed from the cast special-shaped surface structure. At this time, the end of the embedded rod 501 is located in the groove where the support member 51 is located, and the end is not flush with the surface of the special-shaped surface structure, but is located in the groove. After that, it is only necessary to use cement to seal the groove hole to effectively avoid rust and redness.

[0042] In order to further explain the specific structure of the support member 51, the support member 51 includes a shell 511 and a stud nut 512, the stud nut 512 is coaxially sleeved in the shell 511 and axially slidably connected to the shell 511; the embedded rod 501 and the disassembly rod 502 are respectively screwed to the two ends of the stud nut 512; the inner wall of the shell 511 is provided with a plurality of flanges 513 protruding inwardly, and the end of the flange 513 is provided with a limit plate 514, and the limit plate 514 is used to be attached to the outer edge wall of the stud nut 512 to limit the rotation of the shell 511 and the stud nut 512; the top end of the stud nut 512 extends outward to form a limit plate 515, and the diameter of the limit plate 515 is slightly smaller than the outer diameter of the small diameter end face of the shell 511.

[0043] With the above arrangement, when disassembling, the housing 511 can be pulled out first, and then the stud nut can be screwed out with a wrench, which further facilitates disassembly.

[0044] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
