Description
Technical Field
The utility model relates to an automobile engine spare part production and processing equipment field specifically is an engine support die casting die.
Background
In automobile engine support die-casting production process, remain on the mould after the processing finishes usually and have the sweeps, do not clear up well, and common way is to adopt the brush to sweep remaining sweeps on the mould to the collection incasement to reach the purpose of clearing up the mould, but in the actual operation in-process, the effect that adopts the brush to clear up is very limited, in case misoperation will be difficult to more clear up in sweeps into "dead angle" region with the sweeps.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an engine support die casting die can the efficient clear up remaining sweeps on the mould, does not keep "dead angle".
The technical scheme of the utility model as follows:
the utility model provides an engine support die casting die, including die holder and lower mould, its characterized in that: the upper surface of the lower die base is respectively provided with a plurality of waste chip collecting holes around the periphery of the lower die, step holes with small upper parts and large lower parts are respectively arranged below each waste chip collecting hole in the lower die base, the top ends of the step holes are respectively communicated with the waste chip collecting holes correspondingly, the bottom ends of the step holes are closed, pistons with convex-shaped cross sections are respectively arranged in the step holes, the upper parts of the pistons are respectively positioned in the upper holes of the step holes, the lower parts of the pistons are respectively positioned in the lower holes of the step holes, the pistons respectively block the step holes, and springs are respectively connected between the bottom ends of the pistons and the bottom surfaces of the step holes; and air outlet holes which are correspondingly communicated with the lower holes of the stepped holes are respectively formed in the outer sides of the lower die seats, and the air outlet holes are respectively connected with air outlet pipes connected with an external induced draft fan.
The die-casting die for the engine bracket is characterized in that: the plurality of waste chip collecting holes are tapered holes with large upper parts and small lower parts respectively.
The die-casting die for the engine bracket is characterized in that: the plurality of waste chip collecting holes and the step holes below the waste chip collecting holes are vertically arranged.
The die-casting die for the engine bracket is characterized in that: the air outlet holes are respectively arranged transversely and correspondingly positioned below the pistons.
The utility model has the advantages that:
the utility model discloses simple structure sets up the sweeps and collects the hole around the mould, and this sweeps collection hole can be located the optional position, including some "dead angle" regions, set up rather than communicating and blocked up by the piston step hole in the below in sweeps collection hole, set up rather than communicating and external draught fan's venthole in one side in step hole, the draught fan during operation makes the downthehole negative pressure that produces of step, forces the piston to move down, and the sweeps collection hole switches on, can the efficient clear up the remaining sweeps on the mould, and the clearance is effectual, does not keep "dead angle".
Drawings
Fig. 1 is a schematic structural view of the waste chip collecting hole of the present invention when being plugged.
Fig. 2 is the structure diagram of the utility model when the sweeps collecting hole is switched on.
Detailed Description
Referring to the attached drawings, the die-casting die for the engine bracket comprises a lower die base 1 and a lower die 2, wherein a plurality of waste collecting holes 3 are respectively formed in the upper surface of the lower die base 1 around the periphery of the lower die 2, step holes 4 with small upper parts and large lower parts are respectively formed in the lower die base 1 below each waste collecting hole, the top ends of the step holes 4 are respectively and correspondingly communicated with the waste collecting holes 3, the bottom ends of the step holes are sealed, pistons 5 with convex-shaped cross sections are respectively arranged in the step holes 4, the upper parts of the pistons 5 are respectively located in the upper holes of the step holes, the lower parts of the pistons 5 are respectively located in the lower holes of the step holes, the pistons 5 respectively block the step holes, and springs 6 are respectively connected between the bottom ends of the pistons 5 and the bottom surfaces of the step holes; the outer side of the lower die holder 1 is respectively provided with air outlet holes 7 correspondingly communicated with the lower holes of the stepped holes 4, and the air outlet holes 7 are respectively connected with air outlet pipes connected with an external induced draft fan.
The utility model discloses in, a plurality of sweeps collect hole 3 and be big-end-up's bell mouth respectively.
A plurality of sweeps collect hole 3 and step hole 4 of its below all are vertical setting.
The air outlet holes 7 are respectively arranged transversely and correspondingly below the pistons 5.
The invention is further described below with reference to the accompanying drawings:
a plurality of sweeps collecting hole 3 are located the upper surface of die holder 1 to around the lower mould 2, can be located the optional position, including some "dead angle" regions, the step hole at place is blocked up respectively to piston 5.
When the induced draft fan is started to work, negative pressure is formed in the lower hole of the stepped hole 4, the piston 5 is forced to move downwards until the plurality of the scrap collecting holes 3 are correspondingly communicated with the air outlet holes 7, the spring 6 is in a compressed state at the moment, scraps on the die are quickly brought out through the plurality of the scrap collecting holes 3, the stepped hole 4 and the air outlet holes 7, and the spring 6 is continuously in a compressed state under the action of air flow; after the induced draft fan stops working, the air current disappears, the spring 6 resets, pushes the piston 5 to reset, and the step holes are blocked respectively again.
The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention, and the modifications and improvements made by the technical solutions of the present invention should fall into the protection scope of the present invention without departing from the design spirit of the present invention.
