Abstract
The invention discloses a core-pulling mechanism of a hot core box die, which comprises a cylinder support, a cylinder fixed plate arranged on the cylinder support, a cylinder arranged on the cylinder fixed plate, a cylinder arranged on the cylinder fixed plate, and a cylinder connecting shaft the lower end of which passes through the cylinder fixed plate. The core-pulling mechanism of the hot core box die is characterized in that: both sides on the lower part of a core-pulling connecting frame are connected with a core-pulling block respectively by a first core-pulling connecting block and a second core-pulling connecting block; a hoop on the upper part of the core-pulling connecting frame is connected with the lower end of the cylinder connecting shaft; the upper ends of two guide pillars are connected on the cylinder support by end covers, while the lower ends thereof are matched with guide holes on both sides of the core-pulling connecting frame; the core-pulling connecting frame and the core-pulling block connected with the core-pulling connecting frame can slide up and down along the two guide pillars; and the lower end of the core-pulling block is connected with a sand core. The invention has the advantages that the core-pulling mechanism avoids the problem that the cylinder is influenced by high temperature; the sealing component is also not easy to be aged; and the core-pulling mechanism also avoids the phenomenon that the strip core-pulling block is blocked.
Description
Technical field
The present invention relates to the oblique core-pulling mechanism of hot box process mould, relate to particularly that strip is loosed core or the core-pulling mechanism of a plurality of moulds of loosing core.
Background technology
At present, casting industry generally adopts hot box process to make core, and the manufacturing of the core-pulling mechanism of hot box mould then is the key that hot box process is implemented.The core-pulling mechanism of existing hot box mould generally adopts the cylinder connecting axle directly the cylinder and the piece of loosing core to be linked together.Its shortcoming is: the one, and temperature is higher during the hot box mold work, is 250～300 ℃, and heat can directly pass on the cylinder by the cylinder connecting axle, causes the cylinder seal component ageing to be lost efficacy; The 2nd, for the strip piece of loosing core,, then can cause the piece unbalance stress of loosing core if the cylinder installation site is improper, the piece of loosing core when loosing core is very easily stuck.
Summary of the invention
The core-pulling mechanism that the purpose of this invention is to provide a kind of hot box mould, it is rational in infrastructure, easy to assembly, can make cylinder not be subjected to mould temperatures involved, potted component to be not easy to wear out, and can also avoid the strip easy stuck phenomenon of piece of loosing core to take place.
The core-pulling mechanism of a kind of hot box mould of the present invention, comprise that the lower end is located at cylinder support on the hot box mould, is located at air cylinder fixed plate on the cylinder support, is located at the cylinder connecting axle that air cylinder fixed plate is passed in cylinder on the air cylinder fixed plate and lower end, is characterized in that:
The loose core both sides, bottom of link are connected with the piece of loosing core by first contiguous block and second contiguous block of loosing core of loosing core respectively, and the anchor ear that is located at the link top of loosing core is connected with the lower end of cylinder connecting axle;
The upper end of two guide pillars is connected on the cylinder support by end cap, and the lower end of two guide pillars cooperates with the pilot hole of the link both sides of loosing core, and loose core link and the connected piece of loosing core can slide up and down along two guide pillars;
The loose core lower end of piece is connected with core.Between each parts of this mechanism by bolt and bolting.
Beneficial effect of the present invention: because the cylinder connecting axle directly do not link together the cylinder and the piece of loosing core, thereby avoided cylinder to be subjected to the mould temperatures involved, potted component also is not easy to wear out, and in addition, has also avoided growing the bar shaped stuck phenomenon of piece of loosing core and has taken place.
Description of drawings
Fig. 1 is the structural representation of invention.
Fig. 2 is the A-A profile (part) of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
Referring to the core-pulling mechanism of a kind of hot box mould illustrated in figures 1 and 2, comprise that the lower end is located at cylinder support 4 on the hot box mould 12, is located at air cylinder fixed plate 8 on the cylinder support, is located at the cylinder connecting axle 9 that air cylinder fixed plate is passed in cylinder 6 on the air cylinder fixed plate and lower end; The loose core both sides, bottom of link 3 are connected with the piece 13 of loosing core by first contiguous block 1 and second contiguous block 14 of loosing core of loosing core respectively, and the anchor ear 11 that is located at link 3 tops of loosing core is connected with the lower end of cylinder connecting axle 9; The upper end of two guide pillars 10 is connected on the cylinder support 4 by end cap 5, and the lower end of two guide pillars cooperates with the pilot hole of link 3 both sides of loosing core, and loose core link 3 and the connected piece 13 of loosing core can slide up and down along two guide pillars; The loose core lower end of piece 13 is connected with core 15.Fixing between each parts of this mechanism by bolt 2 and bolt 7.
Core-pulling mechanism installs the piece 13 of loosing core, first the loose core contiguous block 14, the link 3 of loosing core, anchor ear 11 of contiguous block 1, second of loosing core and moves as a global facility, when loosing core, cylinder provides power to act on the above-mentioned global facility by cylinder connecting axle 9, and by guide pillar 10 slips, to extract core 15.
Claims (2)
