Description
Technical field
The utility model relates to mould applications.
Background technology
Die casting is a kind of method of casting liquid forging, and die casting is a kind of technique completed on die casting die forging machine.During die casting, molten metal first fills in the die cavity of the die casting on type entrance pressure casting die forging machine, along with the cooling procedure pressurization forging of molten metal, the mechanical performance of metal blank is improved, obtains die casting product.In prior art, the shape of the die cavity of a die casting is changeless, and therefore correspondingly can only produce a kind of die casting product, namely often produce a kind of die casting product and will produce a kind of die casting, cost is very high.
A kind of die casting of current existence, it comprises die frame, die cavity is established in die frame, the first implementation block and second parallel before and after establishing in die cavity carries out block, first carries out block offers the sleeve pipe running through the first implementation block in one end, and the sleeve pipe other end stretches out die frame, internal surface of sleeve pipe is provided with internal thread, second carries out establishing patty cavity in block, patty insert is established in cavity, insert is carried out the side of block side is fixedly connected with screw rod near first, described screw rod passes and stretches out die frame in sleeve pipe, described casing inner diameter is slightly larger than screw diameter, and the internal thread of internal surface of sleeve pipe matches with external screw thread on screw rod, one end that screw rod stretches out die frame is provided with handle.Regulated the size of die cavity by rotary screw, because transfer force is to opposite direction lead-screw in press casting procedure, make to there is very large interaction force between the screw thread on screw rod and mould bases, very easily make deformed threads, cause stuck, make failure of apparatus.
Utility model content
The utility model is intended to provide a kind of and avoids stuck adjustable compression mod.
Adjustable compression mod in this programme, comprise mould bases, push rod, described mould bases inside is provided with die cavity, this die cavity has the inlet for being pressed into point molten metal, the end of described push rod is provided with piston, push rod is through mould bases outer wall, piston stretches in die cavity and also contacts with mould intracavity wall, sealing inner sleeve is adopted to connect between push rod and mould bases outer wall, it is characterized in that: described push rod is provided with tooth bar away from one end of piston, tooth bar is provided with the gear be connected with tooth bar on one side, gear side is provided with ratchet, this ratchet is connected with ratchet, the elastic component of reset is provided with between this ratchet and hinged of ratchet.
Beneficial effect: point molten metal is pressed into die cavity by inlet, and die cast under stress; Because the tooth bar on gear and push rod is connected, pinion rotation, drives push rod to slide, and the piston in die cavity in the drive lower slider of push rod, can change the size of die cavity, to realize the die casting of different size workpiece; Gear side is provided with ratchet, and due to the restriction of ratchet, gear cannot reversely rotate, and therefore, realizes the fixing of piston in press casting procedure, ensures that the size of die cavity immobilizes.Adopt such scheme, compared with existing screw drive, avoid stuck phenomenon, make the adjustment of cavity dimension more smooth.
Further, the position that described push rod runs through mould bases is provided with prismatic section, and mould bases is provided with prismatic hole of matching with this prismatic section, and diamond-shaped outline both ensure that push rod slided in mould bases, and contact surface is more, solid and reliable simultaneously.
Further, described gear is provided with the rocking bar for swing pinion, and shake rocking bar carrys out swing pinion, makes the rotation of gear more laborsaving, convenient.
Further, described mould bases comprises top mold frame and lower mold holder, and top mold frame is connected by bolt with lower mold holder, takes upper and lower mould bases apart, is convenient to clean inside and keep in repair, bolt firm and reliable connection and be convenient to dismounting.
Further, described push rod is provided with handle away from the end, one end of piston, and gear and handle can be used to promote push rod simultaneously, reduces labour intensity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adjustable compression mod embodiment of the utility model.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: top mold frame 1, lower mold holder 11, inlet 12, push rod 2, piston 21, prismatic section 22, tooth bar 23, handle 24, gear 3, rocking bar 31, ratchet 4, ratchet 41.
Embodiment is substantially as shown in Figure 1:
Adjustable compression mod in this programme, comprise mould bases, push rod 2, mould bases inside is provided with die cavity, this die cavity has the inlet 12 of press-in point molten metal, the end of push rod 2 is connected with piston 21, push rod 2 is through mould bases outer wall, piston 21 stretches in die cavity and also contacts with mould intracavity wall, sealing inner sleeve is adopted to connect between push rod 2 and mould bases outer wall, push rod 2 is processed with tooth bar 23 away from one end of piston 21, the gear 3 be connected with tooth bar 23 is installed on one side, one-body molded on gear 3 side have ratchet 4, ratchet 41 is connected with ratchet 4, this ratchet 41 is provided with the elastic component of reset.
The position that push rod 2 runs through mould bases is provided with prismatic section 22, and mould bases matches with this prismatic section 22 is provided with prismatic hole, and diamond-shaped outline both ensure that push rod 2 slided in mould bases, and contact surface is more, solid and reliable simultaneously.Gear 3 is connected with the rocking bar 31 for swing pinion 3, shake rocking bar 31 carrys out swing pinion 3, makes the rotation of gear 3 more laborsaving, convenient.
Mould bases comprises top mold frame 1 and lower mold holder 11, and top mold frame 1 is connected by bolt with lower mold holder 11, takes upper and lower mould bases 11 apart, is convenient to clean inside and keep in repair, bolt firm and reliable connection and be convenient to dismounting.Push rod 2, away from one end welding edges jug 24 of piston 21, can two people promote push rod 2 simultaneously, reduces labour intensity.
Operation principle: point molten metal is pressed into die cavity by inlet 12, and die cast under stress; Because the tooth bar 23 on gear 3 and push rod 2 is connected, gear 3 rotates, and drives push rod 2 to slide, and the piston 21 in die cavity in the drive lower slider of push rod 2, can change the size of die cavity, to realize the die casting of different size workpiece; Ratchet 4 is equipped with in side with gear 3, and due to the restriction of ratchet 41, gear 3 cannot reversely rotate, and therefore, realizes the fixing of piston 21 in press casting procedure, ensures that the size of die cavity immobilizes.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
