Abstract
The utility model discloses a box-free sand mold locking device. The box-free sand mold locking device comprises a depression bar (1), wherein the two ends of the depression bar (1) are connected with pull rods through locking clamps (2); locking hooks (3) are arranged on the bottom parts of the pull rods. The box-free sand mold locking device has a unique and reliable structure. The device has very low impact on a sand mold in a locking process, and accumulated sand in a mold cavity in the locking process can be reduced. The box-free sand mold locking device can be used for various types of sand molds in common, and has high interchangeability. According to the box-free sand mold locking device, various types of sand molds can be locked reliably, and the accumulated sand in the mold cavity caused by impact can be reduced, so that sand inclusion defects of casts are reduced. Very good economic effects can be produced after long-term use.
Description
Technical field
the utility model relates to a kind of without case sand mold locking device, belongs to without case sand casting technical field.
Background technology
at casting industry, be to adopt sandbox to cast mostly, so current locking device mainly designs for sandbox.When adopting resin bonded sand mould to carry out casting without case, at present inapplicable for the locking device of sandbox, during locking, impulsive force is larger, easily causes die cavity inner product sand, affects castability.
Summary of the invention
the purpose of this utility model is, provides a kind of without case sand mold locking device, to solve, adopts the larger problem of impulsive force while lock without case sand mold, and minimizing die cavity inner product sand, to improve castability.
the technical solution of the utility model:
without a case sand mold locking device, comprise press strip, press strip two ends are connected with pull bar through locking clamp, and pull bar bottom is provided with latch hook.
aforementioned without in case sand mold locking device, described pull bar comprises pull bar epimere, pull bar epimere bottom and the welding of pull bar hypomere; Pull bar epimere is provided with one group of draw-in groove, and pull bar hypomere bottom is provided with latch hook.
aforementioned without in case sand mold locking device, be located at two latch hooks on pull bar hypomere and be all inwardly symmetrical arranged.
aforementioned without in case sand mold locking device, described press strip two ends are provided with open slot.
aforementioned without in case sand mold locking device, described pull bar epimere is positioned at open slot, and pull bar epimere is provided with one group of draw-in groove.
aforementioned without in case sand mold locking device, described locking clamp is provided with bayonet lock, and bayonet lock and draw-in groove are pegged graft.
aforementioned without in case sand mold locking device, described locking clamp is provided with screwed hole, and screwed hole and bolt are spirally connected.
aforementioned without in case sand mold locking device, described locking clamp bottom is provided with baffle plate.
compared with prior art, the utility model structure is unique, reliable.This device locking process is very little to the impact of sand mold, can reduce the generation of die cavity inner product sand in locking process.All kinds of sand molds all can be general, exchanges functional.The utility model can complete the locking of all kinds of sand molds reliably, reduces the long-pending sand of the die cavity producing because of impact, thereby reduces the burning into sand defect of foundry goods.Long-term use will produce very good economic effect.

being labeled as in accompanying drawing: 1-press strip, 2-locking clamp, 3-latch hook, 4-pull bar epimere, 5-pull bar hypomere, 6-open slot, 7-draw-in groove, 8-bayonet lock, 9-screwed hole, 10-bolt, 11-baffle plate, 12-die cavity, 13-bottom board, 14-pours into a mould cover plate.
The specific embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to any restriction of the present utility model.
without a case sand mold locking device, as shown in Figure 1, comprise press strip 1, press strip 1 two ends are connected with pull bar through locking clamp 2, and pull bar bottom is provided with latch hook 3.Described pull bar comprises pull bar epimere 4, pull bar epimere 4 bottoms and 5 welding of pull bar hypomere; Pull bar epimere 4 is provided with one group of draw-in groove 7, and pull bar hypomere 5 bottoms are provided with latch hook 3.Being located at two latch hooks 3 on pull bar hypomere 5 is all inwardly symmetrical arranged.Described press strip 1 two ends are provided with open slot 6.Pull bar epimere 4 is positioned at open slot 6, and pull bar epimere 4 is provided with one group of draw-in groove 7.As shown in Figure 2, locking clamp 2 is provided with bayonet lock 8 to described locking clamp 2, and bayonet lock 8 is pegged graft with draw-in groove 7.Locking clamp 2 is provided with screwed hole 9, and screwed hole 9 is spirally connected with bolt 10.Locking clamp 2 bottoms are provided with baffle plate 11.
fig. 3 is used the utility model locking without the schematic diagram of case resin bonded sand mould, and Fig. 4 is the partial enlarged drawing of pull bar and press strip 1 coupling part in Fig. 3.As seen from Figure 3, this example adopts four pull bars, first the latch hook of pull bar bottom 3 is hooked in bottom board 13 bottoms, again the open slot 6 at pressing plate 1 two ends is enclosed within to pull bar epimere 4, then the bayonet lock 8 on locking clamp 2 is inserted in the draw-in groove 7 that pull bar epimere 4 is suitable, because pull bar epimere 4 is provided with 7, one groups of draw-in grooves 7 of one group of draw-in groove, is divided into two row and is interspersed and can meets the needs of various height sand molds.In the screwed hole 9 again bolt 10 being screwed on locking clamp 2, by bolt 10, compress press strip 1, by press strip 1, coupling mechanism force is passed to the cast cover plate 14 at die cavity 12 tops, make bottom board 13, die cavity 12 and pour into a mould 14 one-tenth of cover plates as a whole.Press locking clamp 2 to be provided with baffle plate 11, can prevent pressing plate 1 lateral displacement.
