This programme according to the hole area on the machined surfaces of four cylinder box castings four cylinder box molds die cavity inner surface
Corresponding site meshed grooves are set, the gas on the machined surface for the four cylinder box castings that so can effectively eliminate die cast
Hole.The structure of the cylinder box mold of this programme four is simple, easy to make, and small, saving Mold Making cost is changed to mould structure, and
The problem of easily producing stomata can be effectively improved on four cylinder casing machined surfaces.
Preferably, four cylinder box molds include upper mould and lower mould, the meshed grooves are arranged on the lower surface of mould.
Preferably, meshed grooves include some interlaced longitudinal flutings and transverse concave groove, the following table of the upper mould
Face is provided with running channel, and at least part longitudinal fluting is connected with running channel in the longitudinal fluting.The longitudinal direction of this programme structure is recessed
Groove is connected with running channel, so further can effectively eliminate the stomata on the machined surface of four cylinder box castings.
Preferably, meshed grooves include some interlaced longitudinal flutings and transverse concave groove, the following table of the upper mould
Face is provided with running channel, and at least parts transversely groove is connected with running channel in the transverse concave groove.The transverse direction of this programme structure is recessed
Groove is connected with running channel, so further can effectively eliminate the stomata on the machined surface of four cylinder box castings.
Preferably, meshed grooves include some interlaced longitudinal flutings and transverse concave groove.
Preferably, the A/F of longitudinal fluting and transverse concave groove is 1.5-1.7mm.
Preferably, each longitudinal fluting is parallel to each other, and the spacing between adjacent two longitudinal fluting is 4-6mm；Each transverse direction
Groove is parallel to each other, and the spacing between adjacent two transverse concave groove is 4-6mm.
Preferably, the pattern draft of longitudinal fluting and transverse concave groove is 0.3-0.5 degree.
Preferably, the groove depth of longitudinal fluting and transverse concave groove is 0.4-0.6mm.
A kind of preparation method for the four cylinder box molds for eliminating machined surface stomata, comprises the following steps successively：
A, four cylinder casing samples are made using existing four cylinders box mold；
B, the hole area on the machined surface of four cylinder casing samples is observed, and according to the position of the hole area corresponding
Meshed grooves are processed on the die cavity inner surface of four cylinder box molds.
The beneficial effects of the invention are as follows：With simple in construction, easy to make, mould structure is changed it is small, it is cost-effective
Feature, and the problem of easily producing stomata can be effectively improved on four cylinder casing machined surfaces.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the upper mould of four cylinder box molds of the elimination machined surface stomata of the present invention.
Fig. 2 is the partial enlarged drawing at A in Fig. 1.
In figure：Upper mould 1, running channel 2, meshed grooves 3, longitudinal fluting 31 and transverse concave groove 32.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Embodiment 1：As shown in figure 1, a kind of four cylinder box molds for eliminating machined surface stomata include upper mould 1 and lower mould.With
The die cavity inner surface of four corresponding cylinder box molds of the machined surfaces of four cylinder casings is provided with meshed grooves 3.Meshed grooves are used for
Eliminate the stomata of the machined surface of four cylinder casings.Meshed grooves in the present embodiment are arranged on the lower surface of mould.Meshed grooves
Including some interlaced longitudinal flutings 31 and transverse concave groove 32.The lower surface of upper mould is provided with running channel 2.In longitudinal fluting extremely
