Description
Technical Field
The utility model relates to the technical field of casting molds, in particular to an adjustable casting mold with a micro-structural cavity.
Background
For cast castings, such as compressor housings and the like, there is typically a microstructure thereon, typically at the end of the casting body, which is typically of deep and narrow structural characteristics. The microstructure cavities used to form the microstructure in the mold cavity correspondingly also have deep and narrow structural features, and are typically located relatively far from the gate. Before casting production, when the thermal insulation coating is sprayed on the die cavity, the coating is difficult to be sprayed on the two side surfaces of the cavity vertical to the depth direction due to the narrow space and the deep depth of the micro-structure cavity, so that the coating in the micro-structure cavity is unevenly sprayed, and the thermal insulation effect of the cavity is affected during casting. And, because structural feature is far away from runner position, easily cause the casting not enough, influence shaping quality, easily lead to the foundry goods to scrap.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides an adjustable casting mold with a micro-structural cavity, which aims to solve the technical problem of poor casting molding quality caused by insufficient casting due to insufficient spraying of the micro-structural cavity in a mold cavity.
The technical scheme adopted by the utility model is as follows:
the utility model provides a casting mould with adjustable micro-structure chamber, includes mould, lower mould and looses core, be equipped with the guide way on the die joint of last mould or lower mould, be equipped with the loose core that can follow its removal in the guide way, be equipped with first shaping portion in the die cavity of last mould or lower mould, first shaping portion is located the inner of guide way, the inner of loosing core is formed with second shaping portion, works as loose core to the inner of guide way removes to second shaping portion with first shaping portion dock, forms complete micro-structure chamber.
The further technical scheme is as follows:
the core pulling device is driven by the linear driving device to move along the guide groove.
The fixed end of the linear driving device is arranged outside the upper die or the lower die.
When the loose core moves towards the outer end of the guide groove, the second forming part is away from the first forming part, so that the cavity area formed by the first forming part, the guide groove and the second forming part is enlarged.
The depth of the micro-structural cavities is greater than the width.
The beneficial effects of the utility model are as follows:
the utility model utilizes the core pulling and the mould to form the micro-structure cavity, can increase the size of the micro-structure cavity along the width direction by moving the core pulling, is beneficial to enabling the two side surfaces perpendicular to the depth direction to be sprayed to the paint, ensures that the paint of the micro-structure cavity is uniformly sprayed, and improves the heat preservation effect. The problem that the casting is scrapped due to insufficient casting caused by incapability of applying paint to the cavity and the fact that the cavity is far away from the pouring gate is avoided.
The utility model realizes on-line coating of the die and cleaning of aluminum sticking. The time for cleaning the die after the die is taken off is reduced, the labor is saved, and the production flow is shortened.
Additional features and advantages of the utility model will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.

Detailed Description
The following describes specific embodiments of the present utility model with reference to the drawings.
As shown in fig. 1, 2 and 3, the casting mold with adjustable micro-structural cavity of this embodiment includes an upper mold 1, a lower mold 2 and a core pulling 4, a guide groove 6 is provided on a parting surface of the lower mold 2, a core pulling 4 capable of moving along the guide groove 6 is provided in the guide groove 6, a first forming portion 9 is provided in a cavity 8 of the lower mold 2, the first forming portion 9 is located at an inner end of the guide groove 6, a second forming portion 41 is formed at an inner end of the core pulling 4, and when the core pulling 4 moves to the inner end of the guide groove 6 to butt joint the second forming portion 41 and the first forming portion 9, a complete micro-structural cavity 7 is formed.
Specifically, the core back 4 is driven by the linear driving device 3 to move along the guide groove 6.
Specifically, the fixed end of the linear driving device 3 is installed outside the upper die 1.
The linear drive 3 is preferably a cylinder.
It will be appreciated that when the core back 4 moves toward the outer end of the guide groove 6, the second molding portion 41 moves away from the first molding portion 9 accordingly, so that the cavity area formed by the first molding portion 9, the guide groove 6 and the second molding portion 41 is enlarged.
Specifically, referring to fig. 3, the depth of the microstructure cavities 7 is greater than the width thereof.
It can be understood that the micro-structural cavity of the embodiment is correspondingly communicated with the cavity of the upper die after the upper die and the lower die are clamped, so as to form a complete closed cavity structure. The guide groove and the first molding portion are not limited to being provided in the cavity of the lower die, but may be provided in the cavity of the upper die, depending on the casting structure and the need.
The casting mould with adjustable micro-structure chamber of this embodiment, before using, remove the loose core and remove towards the guide way outer end direction, second shaping portion moves along with the loose core for the width in the micro-structure chamber of dark narrow originally becomes big, during the spraying, through coating spraying mechanism along the die cavity inner wall spraying heat preservation coating of mould, lower mould respectively in the direction of perpendicular to die joint, in the spraying process, because the width in the micro-structure chamber of dark narrow becomes big, more be favorable to the coating to be spouted on the side of cavity (i.e. in original first shaping portion and the second shaping portion). After the spraying is finished, the movable loose core moves towards the inner end direction of the guide groove, so that the first forming part and the second forming part are in butt joint to form a micro-structure cavity. The coating is uniformly and completely coated in the micro structural cavity, so that the heat preservation effect of the micro structural cavity after die assembly is effectively enhanced.
Fig. 4 is a schematic view showing a state of the casting 5 in the cavity of the mold after casting molding by using the mold according to the embodiment of the present utility model. The upper mold is hidden in the figure for clarity of the molded structure. The microstructure 51 on the casting 5 is molded in the microstructure cavity, and after the core is removed after molding, smooth demolding of the microstructure 51 is facilitated. And after demoulding, the width of the micro structural cavity is increased, so that the inner wall of the structural cavity is convenient to clean by sticking aluminum.
