Abstract
The utility model provides a water pump core-pulling device of a gear transmission mould. The water pump core-pulling device of the gear transmission mould comprises a stationary mould and a movable mould connected with a water pump. The stationary mould comprises a first rack, and the movable mould comprises a mould core and an inclined ejector rod, wherein the mould core is provided with an inside inclined hole, the inclined ejector rod abuts against the inside inclined hole in a matched mode, a second rack which can move is installed on the inclined ejector rod, and a gear which is respectively meshed with the first rack and the second rack is installed between the first rack and the second rack. According to the water pump core-pulling device of the gear transmission mould, mutual movement of mould assembly and separation between the movable mould and the stationary mould is utilized, the first rack of the stationary mould drives the second rack of the movable mould to move through the gear, and then the second rack drives the inclined ejector rod to complete core pulling, so that the water pump core-pulling device of the gear transmission mould is simple in structure and convenient to install.
Description
Technical field
The utility model relates to the technical field of loosing core of foundry goods, especially, relates to a kind of water pump core-pulling device of gear drive mould.
Background technology
At present, general mould all is shaped with interior inclined hole (tiltedly blind hole), and the core-pulling device of inclined hole adopts oil cylinder or spring to drive push rod (in take out piece) as power to come direct pumping mode usually in the prior art, the shortcoming of its existence is: structure is comparatively complicated, when being installed, oil cylinder or spring bother, and especially easily and the hole, water route of mould interfere, affect the cooling effect of mould.
The utility model content
The utility model purpose is to provide a kind of water pump core-pulling device of gear drive mould, to solve the technical problem of existing core-pulling device complex structure, installation oil cylinder or spring trouble.
For achieving the above object, according to an aspect of the present utility model, a kind of water pump core-pulling device of gear drive mould is provided, comprise quiet mould, the dynamic model that links to each other with water pump, quiet mould comprises the first tooth bar, dynamic model comprises that the core that is installed with inclined hole in the band pushes up the angle ejector rod of joining mutually with interior inclined hole with core, and angle ejector rod is provided with movably the second tooth bar, is provided with between the first tooth bar and the second tooth bar respectively and the first tooth bar and the second tooth bar meshed gears.
Further, the engagement interlock of the upper surface of the second rack and pinion, the lower surface engagement interlock of the first rack and pinion.
Further, the gear teeth of the gear teeth of the second tooth bar and the first tooth bar are oppositely arranged.
The utlity model has following beneficial effect:
The water pump core-pulling device of gear drive mould of the present utility model utilizes matched moulds and the mutual movement that separates between dynamic model and the quiet mould, the first tooth bar of quiet mould is by the second tooth bar motion of gear driven dynamic model, the second tooth bar drives angle ejector rod again and finishes and loose core, and such is simple in structure, easy for installation.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
