Abstract
The utility model discloses a pressure casting mould for a four-cylinder engine cylinder cover surface. The mould has a movable mould water jacket structure; and the upper surface of a movable mould water jacket is provided with latticed bumps. In the mould, gas produced in a pressure casting process is accommodated by the latticed bumps, so that pores are prevented from being produced on the cylinder cover surface, and the qualification rate of a product is increased.
Description
Technical field
The utility model relates to a kind of four cylinder engine cylinder cap face die casting.
Background technology
Automobile engine cylinder-body is key position parts on the automobile, and its build is bigger, planform complexity, specification requirement height.Molten metal is short at the time compole of high-voltage high-speed retrofilling mold cavity in the press casting procedure, generally only one of in a measure second, or even 1/tens seconds.Advance to water and 2.0L four cylinder engine cylinder block is the center, when watering die cast, aluminium liquid is along the direct injection of cast gate direction.Its cylinder cap face die casting is the cylinder sleeve structure, and perpendicular to the cast gate direction, and distance is shorter, and near the gas the cylinder cap face can't be discharged fully, and pore appears in the cylinder body upper surface when causing the follow-up machined of cylinder body.Therefore cinder ladle should be opened in away from gate end, and with convenient exhaust deslagging, but cylinder sleeve has water jacket to be separated by, and liner backs can't be offered cinder ladle.
Summary of the invention
The purpose of this utility model is in order to solve the easy defective that produces pore in cylinder block and head face die casting surface in the prior art, a kind of four cylinder engine cylinder cap face die casting to be provided.
In order to achieve the above object, the utility model provides a kind of four cylinder engine cylinder cap face die casting, comprises cylinder sleeve, it is characterized in that: the outer surface at cylinder sleeve is provided with the latticed projection that is used for holding the gas that can't discharge.
In the utility model, described latticed projection is square projection or rhombus projection, and the gas that can't discharge is contained in square projection or the rhombus projection.
Compared with prior art, the utility model cylinder cap face die casting utilizes the latticed projection of liner backs, holds the gas that produces in the press casting procedure, eliminates the pore that the cylinder block and head face occurs, and improves the qualification rate of product.
Description of drawings
Fig. 1 is the structural representation of the utility model cylinder cap face die casting;
Fig. 2 is the structure enlarged drawing of dynamic model water jacket among Fig. 1.
Among the figure, 1-dynamic model water jacket, the latticed projection of 2-.
The specific embodiment
Below in conjunction with accompanying drawing the utility model four cylinder engine cylinder cap face die casting is described in detail.
As shown in the figure, the utility model four cylinder engine cylinder cap face die casting is dynamic model water jacket 1 structure, is provided with latticed protruding 2 at dynamic model water jacket 1 upper surface.A small amount of gas that this face can't be discharged during die casting can be involved in latticed protruding 2 the grid when the filling of aluminium liquid, and cylinder body adds partly to be processed grid man-hour, and the cylinder cap face then pore can not occur.Latticed projection is square projection or rhombus projection, and the gas that can't discharge is contained in square projection or the rhombus projection.
Claims (2)
1. a four cylinder engine cylinder cap face die casting comprises dynamic model water jacket (1), it is characterized in that: the upper surface at dynamic model water jacket (1) is provided with the latticed projection (2) that is used for holding the gas that can't discharge.
2. four cylinder engine cylinder cap face die casting according to claim 1 is characterized in that: described latticed projection (2) is square projection or rhombus projection.
