Compared with the prior art, the utility model, designed centre form spraying protection frock, the distance design of the height of baffle according to centre form location terminal surface and centre form parting line, the structure of the centre form parting line of laminating completely of the top shape of baffle has effectively solved the regional mutual pollution problem of losing and coating of mould parting line when sandblast, spraying.
Description
Technical Field
The utility model belongs to the technical field of the mechanical skill and specifically relates to an centre form spraying protection frock.
Background
Aluminum piston gravity casting uses widely metal-type molds. The piston mold has a complex structure and is generally formed by splicing a plurality of components such as a top mold, an outer mold, an insert, a pin, an inner mold and the like. In the casting production process, the piston mold needs to be maintained periodically, and the maintenance is mainly divided into two steps of sand blasting and spraying. The main purpose of sand blasting is to remove aluminum and old paint adhered on the surface of the mould and increase the roughness of the surface of the mould. The purpose of spraying is to make the surface of the mould adhere with a new coating, which is beneficial to improving the temperature of the mould, prolonging the service life of the mould and facilitating the demoulding of the casting.
The geometry of the inner die forms the inner cavity structure of the piston casting and is the most important part in the piston die. In the sand blasting process, the sand grains clean the surface of the mold and cause the loss of the surface of the mold, particularly the loss of a parting surface. The lost damage causes the weight of the casting to be overweight, and the lost damage of the parting surface also causes the inner mold not to be well spliced with other mold components, thereby causing the flash of the casting.
In the spraying process, the part of the inner die, which is in contact with the casting, needs to be sprayed with the heat-insulating coating, and the part of the inner die, which is in contact with other die parts, needs to be sprayed with the diluted graphite emulsion, so that the movement between the dies is facilitated. Different coatings are easy to cause coating pollution in the spraying operation, influence the effect of the mold coating and cause casting defects.
Therefore, an inner mold spraying protection tool needs to be designed to solve the problems of loss of a mold parting line area and mutual pollution of coating during sand blasting and spraying.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art, providing an centre form spraying protection frock to the mutual pollution problem of losing and coating of mould parting line region when solving sandblast, spraying.
In order to achieve the purpose, the utility model relates to an centre form spraying protection frock, including the front side shield, the rear side shield, the screw, adopt the screw-fastening between front side shield and the rear side shield, the front side shield, the bottom of rear side shield is planar structure, planar structure is used for the location, planar structure places on centre form location terminal surface, the centre form is located between front side shield and the rear side shield, the front side shield, the top shape of rear side shield is the same with the structure of centre form joint line, the front side shield, the highly equal interval between centre form location terminal surface and the centre form joint line of rear side shield.
The number of the screws is two, and the screws are respectively positioned at the left side and the right side of the front side baffle and the rear side baffle.
Compared with the prior art, the utility model, designed centre form spraying protection frock, the distance design of the height of baffle according to centre form location terminal surface and centre form parting line, the structure of the centre form parting line of laminating completely of the top shape of baffle has effectively solved the regional mutual pollution problem of losing and coating of mould parting line when sandblast, spraying. The utility model discloses simple structure, the cost is cheap, is convenient for install and dismantles, and the practicality is strong, can satisfy the used jointly of the many sets of moulds of same product.
Drawings
Fig. 1 is a structural diagram of the present invention.
Fig. 2 is a schematic view of the present invention.
Detailed Description
The invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1, fig. 2, the utility model relates to an centre form spraying protection frock, including front side shield, rear side shield, the screw, adopt the screw 3 fastening between front side shield 1 and the rear side shield 2, front side shield 1, rear side shield 2's bottom is planar structure, planar structure places on centre form location terminal surface 6, centre form 4 is located between front side shield 1 and the rear side shield 2, front side shield 1, rear side shield 2's top shape is the same with centre form parting line 5's structure, front side shield 1, rear side shield 2 highly equals the interval between centre form location terminal surface 6 and the centre form parting line 5.
The utility model discloses in, screw 3 is two, is located the left and right sides of front side shield 1 and rear side shield 2 respectively.
The utility model discloses before the sandblast operation, with front side shield 1, on inner mould location terminal surface 6 was put to back side shield 2, then put into the sand blasting machine and carry out the sandblast with the centre form that will be equipped with spraying protection frock, protection centre form parting line 5. And cleaning the surface of the inner mold by using an air gun after sand blasting, preheating the inner mold provided with the spraying protection tool in a 250 ℃ oven for 1 hour, and spraying the surface of the inner mold after the inner mold is taken out of the oven. And finally, loosening the screws 3, taking out the front side baffle 1 and the rear side baffle 2, and performing graphite brushing operation on the bottom area of the inner mold 4.
The utility model discloses an centre form spraying protection frock, the distance design of the height of baffle according to centre form location terminal surface and centre form parting line, the structure of the centre form parting line of laminating completely of the top shape of baffle, the regional mutual pollution problem of losing and coating of mould parting line when effectively having solved the spraying. The utility model discloses simple structure, the cost is cheap, is convenient for install and dismantles, and the practicality is strong, can satisfy the used jointly of the many sets of moulds of same product.
