Description

Sand device is uniformly put in cabinet workpiece casting

Technical field

The utility model relates to one kind to put sand device, and in particular to a kind of cabinet workpiece casting is uniform to put sand device.

Background technique

Lost foam casting is that paraffin similar with casting dimension shape or foam part model bonding are combined into model Cluster is embedded in vibration molding in drystone sand, is poured under negative pressure, model is made to gasify after brushing fireproof coating and drying, liquid gold Category occupies modal position, and the novel casting method of casting is formed after solidification is cooling.

For the casting of the casting of cabinet, especially cylindrical box, need for cabinet model to be put into sandbox, then sand Tank puts sand into sandbox, while circumferentially swinging sand pipe, i.e., ceaselessly surrounds body pivot sand pipe, keep sand slow Ground, equably overlay model, until part model all submerges in sand, in this process, if the necessary sand of sand is in model Surrounding uneven distribution is then easy to cause part model stress deformation, to make to pour the workpiece size generation large error cast out. It is at present usually that worker empirically swings sand pipe, the degree of automation is low, and human cost is high.

Summary of the invention

The purpose of the utility model is to provide a kind of casting of cabinet workpiece uniformly to put sand device, can automatically, equably incite somebody to action Sand is covered on cabinet workpiece, reduces human cost.

To achieve the above object, sand device is uniformly put in the cabinet workpiece casting that the utility model uses, comprising: limit plate is put Sand hose, limit plate are fixed by the hanger for being located at limit plate surrounding, which is equipped with multiple groups and puts sand device, this puts sand device Including symmetrically arranged two arc waist holes, the sand pipe mouth, the conducting mechanism that are movably arranged in arc waist hole, the arc waist hole Radian less than 180 °, the conducting mechanism include with arc waist hole internal diameter cooperation toroidal conductor slot, the toroidal conductor slot It is set to the top or bottom of the limit plate, is provided with drawstring in the toroidal conductor slot, the drawstring and the sand pipe mouth Connection, the toroidal conductor slot are equipped with opening, which is provided with roller, and the starting point of the drawstring and clearing end are wrapped in On the roller, which is driven by motor；The different diameters for putting the arc waist hole in sand device is different.

Further, the arc waist hole put described in adjacent two groups in sand device is staggered in the circumferential.

Further, the center for putting sand device is equipped with central through hole, is equipped with center in the central through hole and puts Sandpipe mouth, the center sand pipe mouth are connected with center and put sand hose.

Preferably, the drawstring is wirerope.

Put sand hose to be connected to silo, put two in sand device sand pipe mouths and be together in series by drawstring, sand pipe mouth with Drawstring moves synchronously, and when rotating electric machine, motor drives roller rotation, so that the drawstring in toroidal conductor slot be driven circumferentially to transport It is dynamic, thus drive two sand pipe opening's edges the movement of arc waist hole, so that sand be made rotatably, equably to fall into sandbox, from And be equably covered on cabinet model, in particular for columnar cabinet model, effect is more preferable；Since setting multiple groups put sand Device, it is ensured that sand is along the radially uniform distribution of cylindrical shape case body Model；It is manual due to not needing to reuse staff Sand is put, therefore reduces human cost.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 be in Fig. 1 A-A to schematic cross-section；

Fig. 3 is B-B direction schematic cross-section in Fig. 1；

In figure: 1. hangers, 2. limit plates, 3. sand pipe mouths, 4. arc waist holes, 5. toroidal conductor slots, 6. drawstrings, 61. rollings Sand hose is put at cylinder, 62. motors, 7. center sand pipe mouths, 71. central through holes, 72. centers, and 8. put sand hose.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing, with the left side Fig. 1 for left direction, with Fig. 1's Top is top.

As shown in Figure 1 to Figure 3, sand device is uniformly put in cabinet workpiece casting, comprising: limit plate 2 puts sand hose 8, limit plate 2 Fixed by the hanger 1 for being located at 2 surrounding of limit plate, 1 upper end of hanger can be fixed in silo, which puts equipped with multiple groups Sand device, it includes symmetrically arranged two arc waist holes 4, the sand pipe mouth being movably arranged in arc waist hole 4 that this, which puts sand device, 3, conducting mechanism, sand pipe mouth 3 is fastened in arc waist hole 4, can be along 4 back and forth movement of arc waist hole；The arc of the arc waist hole 4 Angle is spent less than 180 °, and conducting mechanism includes the toroidal conductor slot 5 with the cooperation of 4 internal diameter of arc waist hole, which is set to The top or bottom of limit plate 2 are provided with drawstring 6 in toroidal conductor slot 5, which connect with sand pipe mouth 3, when drawstring 6 is suitable Toroidal conductor slot 5 when doing circumferential movement, sand pipe mouth 3 can be driven to move synchronously；Toroidal conductor slot 5 is equipped with opening, this is opened It is provided with roller 61 at mouthful, the starting point of drawstring 6 and clearing end are wrapped on the roller 61, which is driven by motor 62； The diameter of the different arc waist holes 4 put in sand device is different.

The present apparatus is fixed between silo and sandbox, and silo stores sand, prevents model in sandbox；Such as Fig. 1 to Fig. 3 institute Show, put sand hose 8 and be connected to silo, puts two in sand device sand pipe mouths 3 and be together in series by drawstring 6, sand pipe mouth 3 and drawing Rope 6 moves synchronously, and when rotating electric machine 62, motor 62 drives roller 61 to rotate, to drive the drawstring 6 in toroidal conductor slot 5 Circumferential movement, thus drive two sand pipe mouths 3 moved along arc waist hole 4, thus make sand rotatably, equably fall into sand In case, to equably be covered on cabinet model, in particular for columnar cabinet model, effect is more preferable；Due to setting Multiple groups put sand device, it is ensured that sand is along the radially uniform distribution of cylindrical shape case body Model；Multiple groups put the curved waist of sand device 4 diameter of hole is different, therefore puts the complementary interference of sand hose 8 above it；Sand is put manually due to not needing to reuse staff, because This reduces human cost.

Since there are gaps between two symmetrically arranged arc waist holes 4, i.e., when sand pipe mouth 3 moves, there are blind areas, should Region cannot be covered by the sand pipe mouth 3 in this group of arc waist hole 4, therefore, further, as shown in Figure 1, adjacent two groups The arc waist hole 4 put in sand device is staggered in the circumferential, such as the design symmetrical above and below of two arc waist holes 4 of outer ring, interior Two arc waist holes 4 of circle symmetrically design, and the sand pipe mouth 3 in inner ring arc waist hole 4 can be to the sand pipe mouth 3 of outer ring Sand is nearby put in movement blind area, avoids and above-mentioned condition occurs.

In order to guarantee middle part also can Synchronous Radio sand, further, as shown in Figure 1 to Figure 3, the centre bit for putting sand device installs There is central through hole 71, which, which can cover in through-hole, is equipped with center sand pipe mouth 7, during which is connected with The heart puts sand hose 72.

In order to improve the wear-resisting property of drawstring 6, it is preferred that drawstring 6 is wirerope.
