Description
Technical field
The present invention relates to a kind of hot box automatic mold splitting device, belong to casting core technical field.
Background technology
Hot box process technology is that the core box with heater injected by sand material foundry sand, thermosetting resin and catalyst mix become, make the sand material of box surface to be heated, binding agent is made within very short time, to get final product polycondensation and harden, form core, there is advantages such as shortening the production cycle, be specially adapted to the high middle or small core of quick production dimensional accuracy.
Dynamic model and the cover half of core box are made by metal material, due to Heavy Weight, when clearing up its inner chamber and maintenance works, a kind of is directly be separated with cover half at the dynamic model of core shooter by core box, core shooter carries out clear up and maintenance work, this can badly influence the production efficiency of core shooter.For this reason another kind be by the dynamic model of core box with cover half after core shooter is separated, under the dynamic model after separation and cover half being winched to line by driving, the inner chamber of dynamic model and cover half is cleared up and maintenance work, carry out matched moulds being transported on core shooter by traveling crane more after hours, this mode also can take core shooter and affect its production efficiency, also need to carry out handling respectively to the dynamic model of core box and cover half respectively, add handling non-cutting time, and to collide with phenomenon to its inner chamber in handling process, there is the risk damaging core box inner-cavity structure.Current majority carries out maintenance under hot box entirety is transported to line by traveling crane, although this mode does not affect the production efficiency of core shooter, but need first core box to be overturn after 90 °, again will play dynamic model with driving to sling separation, two operating personnel are not only needed to carry out the dynamic model of core box and the detached job of cover half, and be easy to cause colliding with of its inner chamber in upset and handling process, and damage can be caused to the interior shape of core box and positioner, also be not easy to the inspection of core box inner chamber and the operation of change core box interior structure simultaneously, under line, dismounting core box needs to expend very large man power and material, cause core box maintenance efficiency not high.
Summary of the invention
The object of this invention is to provide a kind of rational in infrastructure, can fast can be separated and install, and guarantee that the internal structure of core box is not collided dynamic, the cover half of core box, easy to operate, versatility be good, can improve the hot box automatic mold splitting device of core box maintenance operating efficiency.
The present invention is the technical scheme achieved the above object: a kind of hot box automatic mold splitting device, is characterized in that: comprise fixed mechanism for connecting core box cover half with for being connected and the travel mechanism moved horizontally core box dynamic model;
Described fixed mechanism comprises firm banking and is arranged on the first lifting executive item on firm banking, firm banking is provided with first time connector, the mobile side of the first lifting executive item is connected with the first guide rail beam, be connected to the first upper connector on the first guide rail beam and first time connector is slidably connected, two location-plates are arranged on the first guide rail beam and also laterally can adjust along work on the first guide rail beam, and each location-plate is provided with the first connection slotted eye;
Described travel mechanism comprises Mobile base and supporting base, the base plate of Mobile base is provided with second time connector, base plate is provided with roller, it moves side and is connected with the second guide rail beam to be arranged on the second lifting executive item on base plate, be connected to the second upper connector on the second guide rail beam and second time connector is slidably connected, two running fix plates are arranged on the second guide rail beam and also laterally can adjust along work on the second guide rail beam, and each running fix plate is provided with the second connection slotted eye; Described supporting base is provided with horizontal sliding to stretch executive item, horizontal sliding stretch executive item mobile side with passing top board be connected, connecting rod is connected with passing top board and Mobile base, pass top board short transverse is provided with stopper slot, spacing connecting rod be arranged on pass top board stopper slot in and be connected with the second guide rail beam.
The present invention adopts the running fix plate of the location-plate of fixed mechanism and travel mechanism to be connected with the dynamic model runners of core box and cover half runners respectively, the dynamic model of core box is connected on split cast mounting with cover half, because location-plate and running fix plate all can do laterally adjustment along its guide rail beam separately, energy quick adjustment location-plate and running fix Board position, can coordinate with the core box mould runners of different size, conveniently be connected with the core box of each model, size.Mobile base of the present invention is provided with roller, therefore conveniently the distance between Mobile base and holder can be adjusted by the position adjusting Mobile base, the separation of the core box of different depth of inner cavity can be met, when changing core box size in mud core dimensional variations, by regulating the operation that repairs a die of the quick core box of this distance energy, applied widely.The present invention performed by the first lifting and second be elevated executive item in the vertical direction and the horizontal sliding executive item that stretches realize directed movement in the horizontal direction, and quick and stable open core box or matched moulds, stable movement, be separated efficient and convenient, do not need when opening core box to overturn, and also without the need to carrying out handling to the dynamic model of core box after being separated and cover half again, thoroughly solve the problem of core box inner chamber collision, reliably protecting can be realized to core box interior structure, ensure the integrality of core box inner chamber, the size of core box and the size of steady heat core can be guaranteed, and then ensure the quality of core.The present invention drives passing top board and two guide rail beams in moving process by each executive item, make that core box is dynamic, cover half can steadily be separated and matched moulds, core box lifting distance is controlled by the stopper slot passed on top board, reliable operation, the dynamic model of core box and cover half, after cleaning and maintaining, can be carried out matched moulds by core box dynamic model and cover half again fast.The present invention without the need to being separated core box on core shooter, do not affect the production efficiency of core shooter, just can fix with core box through once adjustment and clamping under online by split cast mounting of the present invention, energy is disposable complete the moving of core box, the separation of cover half and assembling operation, does not affect the production efficiency of core shooter.The present invention is rational in infrastructure, simple, improves the security of operating personnel, because versatility is good, easy to use, decrease driving handling number of times, save operating personnel and overhead time, the operating efficiency of core box maintenance and change core box interior structure can have been increased substantially.
