Detailed description of the invention

Fig. 1 is the structural schematic diagram of first mold of the utility model；

Fig. 2 is the structural schematic diagram of second mold of the utility model.

Specific embodiment

Detailed description furtherly is made to the utility model in the following with reference to the drawings and specific embodiments, so as to this field skill Art personnel understand.

As shown in Figs. 1-2, the casting mould with venthole of the utility model, including vertical-parting pouring in vertically clamped moulds One mold 1 and the second mold 2；

First mold 1 includes multiple first casting type chambers 11 and the first running gate system 12, as shown in Figure 1, described Multiple first casting type chambers 11 divide for two rows Heterogeneous Permutation, are also formed with multiple ventholes 13 on first mold 1, and One casting type chamber 11 is correspondingly connected with a venthole 13, and the venthole 13 is flat strip, connects at the top of the flat strip It is connected to the top of first mold 1, the bottom of the flat strip is connected to the top of the first casting type chamber 11；

Second mold 2 includes multiple second casting type chambers 21 and the second running gate system 22, the multiple second casting Part type chamber 21 divides for two rows Heterogeneous Permutation.

Using the casting mould with venthole of the utility model, structure is simple, facilitates casting, can be in time by type chamber In gas discharge, reduce liquid metal filling when the intracavitary gas pressure of type, improve mold-filling capacity, improve the quality of casting.This The gas vent apperance 13 of utility model from the highest point of the first casting type chamber 11 be connected to pouring in vertically clamped moulds vertical-parting first, The top of second mold 1,2 is conducive to gas when casting in timely discharge type chamber and casting mold and sand mold is discharged in casting and coagulates The gas generated during Gu.

The width of the venthole 13 of the utility model is preferably 25mm.The thickness of the venthole 13 is 2mm.Venthole is arranged too small, is unfavorable for the intracavitary gas of type and is discharged in time, and the excessive molten metal that will lead to is filled in venthole, Lead to casting physical breakdown, for this purpose, the size of venthole 13 is optimized into setting, the excessive or mistake for preventing venthole to be arranged It is small.

The venthole 13 for being connected to the first casting type chamber 11 of the utility model is vertical flat strip.Using setting vertically It sets, exhaust pathway is short, is conducive to being quickly discharged by mould upstream by the gas in casting type chamber when casting.

Same principle, it includes bending part and perpendicular that the venthole 13 for being connected to the first casting type chamber 11 described in lower row, which is set as, Straight portion, the lower end of the bending part are connected to the top of the first casting type chamber 11, and the top of the bending part is connected to institute The bottom end of vertical portion is stated, the top of the vertical portion is connected to the top of first mold 1.By ranked first casting type under The venthole that chamber 11 is exhausted rationally is arranged, and exhaust pathway is shortened, by the gas in casting type chamber when being conducive to be poured Be quickly discharged by mould upstream；The white space of mold can be efficiently used simultaneously, reduce mold deadweight, reduce manufacture at This.

First mold 1 and the second mold 2 of the utility model are formed with the dowel hole 14,23 of molding, and close When case, the dowel hole 14,23 of the two is overlapped.First mold 1 and the second mold 2 pass through the positioning pin also cross dowel hole Realize mould assembling positioning.

Although above-described embodiment is made that detailed description to the utility model, it is only the utility model a part Embodiment, rather than whole embodiments, people can also obtain other implementations according to the present embodiment under the premise of without creativeness Example, these embodiments belong to scope of protection of the utility model.
