Abstract
The utility model discloses a differential exhaust structure used in a casting mold. A groove is formed in the lower part of an upper mould of a mold; a cylinder is mounted above the upper mould; the piston rod of the cylinder is connected with a movable block after penetrating through the upper mould; the movable block is arranged in the groove in the upper mould; a square groove is formed in the lower end surface of the movable block; the movable block is driven to move downwards under the driving of the cylinder to be in contact with a side mold of the mold; the groove in the movable block and the upper end surface of the side mold form a through groove of which the periphery is sealed and two ends are open. The differential exhaust structure is used in the casting mold, can automatically regulate the sectional area of an exhaust passage, thereby not only ensuring smooth exhaust, but also avoiding overflow of aluminum liquid, ensuring safety production and improving product quality.
Description
Technical field
The utility model relates to automobile manufacturing field, is specifically related to a kind of differential exhaust structure.
Background technology
The gas extraction system of casting mould, affects the quality that die casting is shaped to a great extent.Exhaust is not smooth, can have a strong impact on casting and fill shape speed, and follow volume gas and choke with resentment phenomenon, therefore always wish that the sectional area of exhaust passage is the bigger the better when Design of Dies, but in the time that sectional area increases to a certain degree, can there is aluminium liquid excessive, easily meet accident, be also unfavorable for that mould fills type pressurize (when low pressure casting) simultaneously.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of differential exhaust structure, for casting mould, can automatically regulate exhaust passage sectional area, not only ensures smooth gas discharge, and avoids aluminium liquid excessive, has ensured safety in production, has improved product quality.
The utility model solves the technical scheme that its technical problem adopts:
A kind of differential exhaust structure, for casting mould, a groove is opened in the patrix bottom of mould; A cylinder is installed in the patrix top of mould, and the piston rod of this cylinder connects a loose piece through after patrix; This loose piece is placed in the groove of upper mould; The lower surface of this loose piece has a square groove; When loose piece is moved downward to the limit mould of contact mould under the drive of cylinder, the groove of loose piece and mould upper surface, limit form that a surrounding is sealed, the groove of both ends open.
Preferably, a side of described patrix is provided with a contact switch, and this switch has one end of contact downwards successively through exposing loose piece lower surface after patrix and loose piece.
Pass through technique scheme, the utility model provides a kind of differential exhaust structure, drives moving up and down of loose piece by cylinder, and exhaust passage sectional area is regulated automatically, in the time filling type and start, loose piece is in upper, keep larger exhaust passage area, ensure smooth gas discharge, normally carry out in order to cavity filling process, in the time filling type and close to an end, exhaust passage sectional area is adjusted to normal exhaust aisle spare automatically, does not make aluminium liquid excessive, ensure the pressurize of casting system simultaneously.The utility model, for casting mould, can regulate exhaust passage sectional area automatically, not only ensures smooth gas discharge, and avoids aluminium liquid excessive, has ensured safety in production, has improved product quality.
Brief description of the drawings

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Shown in Fig. 1, a kind of differential exhaust structure, for casting mould, a groove 4 is opened in patrix 1 bottom of mould; A cylinder 7 is installed in patrix 1 top of mould, and the piston rod of this cylinder 7 is through rear connection one loose piece 3 of patrix 1; This loose piece 3 is placed in the groove (this groove figure does not mark) of upper mould 1; The lower surface of this loose piece 3 has a square groove 4; When loose piece 3 is moved downward to the limit mould 2 of contact mould under the drive of cylinder 7, groove 4 and limit mould 2 upper surfaces of loose piece 3 form the groove of a surrounding sealing, both ends open, wherein, one side of patrix 1 is provided with a contact switch 5, and this switch 5 has one end of contact 6 downwards successively through exposing loose piece 3 lower surfaces after patrix 1 and loose piece 3.
Shown in Fig. 1, when enforcement, patrix 1 below has a groove that holds loose piece 3, and this groove is not expressed in Fig. 1.Loose piece 3 lower surfaces also have a groove 4, this groove 4 in the time of practical application as an exhaust passage; Cylinder 7 moves the electrical system control by Casting Equipment by magnetic valve, and carries out interlock joint control with casting control program, and breakdown action control parameter is set according to casting technological parameter.When cylinder 7 is worked, drive loose piece 3 to move up and down, according to actual needs, if need passage to open completely, ensure smooth gas discharge, loose piece 3 keeps separating with limit mould 2, at this moment the space between the upper surface of limit mould 2 and loose piece 3 lower surfaces is exhaust passage, can ensure like this exhaust effect; If the excessive aluminium liquid that will cause in exhaust passage is excessive, loose piece 3 moves downward under the drive of cylinder 7, now the lower surface of loose piece 3 contacts with the upper surface of limit mould 2, the groove 4 of loose piece 3 forms a passage with the upper surface of limit mould 2, it is penetrating before and after this passage only has, surrounding is closed state, and exhaust passage now just only limits to the passage that this groove 4 forms, and has at this moment just avoided aluminium liquid excessive.Increase in the present embodiment contact switch 5, this switch 5 can be according to contact 6 running that contacts to monitor total with limit mould 2 upper surfaces, once occur that exhaust situation obstructed or discharge occurs, contact switch 5 can send induced signal to control system, make whole mechanism out of service, avoid production accident to occur.
The utility model provides a kind of differential exhaust structure, drive moving up and down of loose piece by cylinder, exhaust passage sectional area is regulated automatically, and in the time filling type and start, loose piece, in upper, keeps larger exhaust passage area, ensure smooth gas discharge, normally carry out in order to cavity filling process, in the time filling type and close to an end, exhaust passage sectional area is adjusted to normal exhaust aisle spare automatically, do not make aluminium liquid excessive, ensure the pressurize of casting system simultaneously.The utility model, for casting mould, can regulate exhaust passage sectional area automatically, not only ensures smooth gas discharge, and avoids aluminium liquid excessive, has ensured safety in production, has improved product quality.
To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.
