Embodiment

With reference to the accompanying drawings and examples, the utility model is described in detail.

A kind of mortar fluidity determines device, as depicted in figs. 1 and 2, including frame 1, the vertically company of slip of frame 1 Disk desktop 2 is connected to, motor 21, driving electricity are provided with frame 1,21 output ends are fixedly connected with for driving disk table The cam 22 that face 2 moves up and down.Lower mould 3 is provided with disk desktop 2, lower mould 3 is set in hollow truncated cone-shaped, the lower lower end of mould 3 Face is provided with rubber ring 4, and rubber ring 4 fits in disk desktop 2 and sealed the gap of lower mould 3 and disk desktop 2.Lower mould 3 upper surfaces are fitted with mould 5, and upper mould 5 is set in tubular, and the upper side wall of mould 5 offers opening 6, be open 6 length and upper mould 5 Internal diameter is equal, as shown in figure 3,6 upper side walls of opening are hinged with cover plate 7, the periphery of cover plate 7 fits in the side wall of opening 6, and opens The upper side wall of mouth 6 sets the limited block 8 that restricted cover plate 7 rotates away from cavity direction in upper mould 5, and baffle plate is additionally provided with frame 1 9, baffle plate 9 can be inserted into opening 6 and for blocking the lower surface of mould 5, and the lower surface of baffle plate 9 fits in the lower upper surface of mould 3, baffle plate 9 Opening is fitted in 6 two sides and to be bonded with the upper inwall of mould 5, and baffle plate 9 be located at the upper inner chamber of mould 5 one end be arranged to in upper mould 5 The corresponding arc surface of chamber, so after in the insertion opening 6 of baffle plate 9, the glue sand flow in mould 5 can be limited and enter lower mould 3.So When needing that glue sand is put into lower mould 3 by upper mould 5, glue sand abuts to cover plate 7 and promotes cover plate 7 to abut to limited block 8, so as to Opening 6 is sealed up by cover plate 7, when glue sand fills up lower mould 3, baffle plate 9 promotes cover plate 7 and rotates cover plate 7, then by opening The upper inner chambers of mould 5 of the insertion of mouth 6, and upper mould 5 and the lower inner chamber of mould 3 are separated, then upper mould 5 and baffle plate 9 are removed again, so passed through While baffle plate 9 strikes off the lower unnecessary glue sand in the upside of mould 3, the glue sand of the upper inner chamber of mould 5 drops to disk desktop when preventing from removing mould 5 2。

Baffle plate 9 and upper mould 5 are removed in order to facilitate synchronous, as shown in figure 1, being provided with fixed group between baffle plate 9 and upper mould 5 Part, fixation kit, including baffle plate 9 is shaped in away from upper one end of mould 5 and perpendicular to the fixed plate 10 of the upper surface of baffle plate 9, and When baffle plate 9 blocks upper 5 inner chamber of mould, fixed plate 10 fits in the upper side wall of mould 5 with the movement of baffle plate 9.Fixed plate 10 is towards upper mould 5 Side wall vertically offer two fixing holes 11, fixing hole 11 is square and is horizontally disposed with, and the upper side wall of mould 5 offers two The individual fixed block 12 corresponding with fixing hole 11, fixed block 12 are set in cuboid.So when baffle plate 9 blocks the upper inner chamber of mould 5 When, fixed block 12 is arranged in corresponding fixing hole 11, and in such pull-up during mould 5, upper mould 5 can drive fixed plate 10 and baffle plate 9 synchronizing movings.

As shown in figure 4, each two side of fixed block 12 is symmetrically arranged with the clip assembly 13 for connecting and fixing plate 10, card Connected components 13 include the buckling groove 14 for being opened in the side wall of fixed block 12, slidably connect clamping bar 15 in buckling groove 14, and block Extension bar 15 and the distance between the upper outer wall of mould 5 are equal with the thickness of fixed plate 10, so when fixed plate 10 slide to clamping bar 15 with it is upper When between the outer wall of mould 5, clamping bar 15 limits fixed plate 10 and slided；Spring 16, the both ends of spring 16 are additionally provided with buckling groove 14 The one end of the bottom surface of buckling groove 14 and clamping bar 15 towards the bottom surface of buckling groove 14 is connected to respectively, and clamping bar 15 is away from fixed block 12 One end is provided with the inclined plane 17 for facilitating fixed plate 10 to slip between clamping bar 15 and the side wall of upper mould 5, and inclined plane 17 deviates from upper mould 5 Direction is set.So when fixed plate 10 is slided along fixed block 12 towards the upper direction of mould 5, and the side wall of fixing hole 11 abuts to inclination During face 17, promote inclined plane 17 and clamping bar 15 is slipped into buckling groove 14, so that fixed plate 10 smoothly slips into clamping bar 15 Between the upper side wall of mould 5, then the push card extension bar 15 of spring 16 is slided away from the direction of buckling groove 14 so as to be blocked by clamping bar 15 Fixed plate 10 is caught, and prevents fixed plate 10 from sliding.

In order to ensure lower mould 3 can move straight up, as shown in figure 1, being provided with lifting assembly on disk desktop 2, carry The telescopic cylinder 18 that component includes being fixedly connected on disk desktop 2 is risen, the output shaft of telescopic cylinder 18 is in be vertically arranged, and flexible The output shaft of cylinder 18 is fixedly connected with connector 19, and the lower surface of connector 19 is fixed with two symmetrical connecting rods 20, Two connecting rods 20 are in horizontally disposed and are fixedly connected with the lower side wall of mould 3, and two connecting rods 20 are symmetricly set in lower mould 3 Both sides.So when needing to be pulled away from lower mould 3, moved up, connected by the drive connection part 19 of telescopic cylinder 18 and connecting rod 20 Bar 20 drives lower mould 3 is synchronous up to move, thus make lower mould 3 move straight up and with glue sand separation.

When needing to determine mortar fluidity, glue sand is flowed into the lower inner chamber of mould 3 by upper mould 5, and glue sand promotes cover plate 7 It is covered on opening 6；Instantly when the inner chamber of mould 3 is filled by glue sand, baffle plate 9 is fitted in into lower mould 3 from the position of opening 6 and inserted in upper mould 5 Chamber, and the inner chamber of mould 5 is blocked, while fixed plate 10 is slid between clamping bar 15 and the outer wall of upper mould 5, and fix fixed plate 10 and the position of baffle plate 9, then mould 5 in pull-up, while drive fixed plate 10 and baffle plate 9 synchronously to leave lower mould 3 by upper mould 5；Again Then driving telescopic cylinder 18 make lower mould 3 vertically with glue sand separation, so that it is guaranteed that when lower mould 3 and glue sand separation, glue sand Keep original shape.

Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
