Specific embodiment
As depicted in figs. 1 and 2, a kind of mold with cow glue powder structure disclosed by the utility model, including cover half 10
With dynamic model 20, mother module core 11 is provided in cover half 10, male die core 21 is provided on dynamic model 20, ox is installed on the male die core 21
Angle cast gate 22, is directly processed on male die core as shown in Fig. 2, cow glue powder can be, and is also possible to as shown in fig. 6, ox horn pours
Mouth 22 and male die core 21 are separate structures.In the present embodiment, also have on the male die core 21 and connect with the cow glue powder 22
Logical injecting hole 210, the injecting hole 210 are externally connected with gas source (not shown), when male die core and cow glue powder are integrated
When structure, injecting hole is the extraneous venthole with cow glue powder of connection directly processed on male die core, gas injection outer end of hole and gas
Source connection is machined with injecting hole, has first on cow glue powder when male die core is separate structure with cow glue powder on male die core
Air guide port 220, when cow glue powder is mounted on male die core, the first air guide port 220 is corresponding with 210 position of injecting hole, so that
Cow glue powder can be connected to extraneous gas source.
It is illustrated in figure 3 schematic diagram when being poured in the prior art using cow glue powder, the sizing material of melting passes through ox
Angle cast gate, which enters type chamber and pours, builds up product 30.When pour build up product 30 after, the remaining sizing material of cow glue powder can also be connected with product
It connects, separate the remaining sizing material in cow glue powder with product, the means generally used are directly with external force by remaining glue
Material is broken with product, product separated with residue sizing material after again to being handled at cast gate.Since sizing material remaining in cow glue powder is filled out
Full entire space, therefore remaining sizing material is separated with product and can only be separated from the weakest point of connection, usually cast gate is connect with product
Place, since there is sizing material certain toughness or viscosity to be easily damaged the inner surface of product, very when being isolated with external force
To formation defect ware.
Such as the mold that Fig. 4 is cow glue powder disclosed by the utility model, there is connection ox horn on the male die core of the mold
The injecting hole of cast gate and extraneous gas source, after by cow glue powder by the sizing material for injecting melting in type chamber, in cow glue powder
Before stock coagulation, gas is injected into cow glue powder by injecting hole, the gas of injection can be from the opening of injecting hole by ox
Sizing material in the cast gate of angle cuts off to form air chamber, therefore after formed product, only has fraction residue sizing material (figure in cow glue powder
In 4 in cow glue powder right side sizing material) connect with product, facilitate and product coupling part remaining sizing material directly from cow glue powder
Middle extraction, simultaneously because high pressure gas is filled in cow glue powder, when remaining sizing material is extracted out from cow glue powder, high pressure gas
With the power for pushing out remaining sizing material, it is also convenient for from cow glue powder extracting remaining sizing material out.Meanwhile as shown in figure 4, from note
Most of remaining sizing material in cow glue powder is also blown into runner by the air injected in stomata, convenient for the collection of remaining sizing material.
As shown in Figure 5 and Figure 6, the cow glue powder includes runner 221 and glue-feeder 222, described 222 one end of glue-feeder with
Runner 221 is connected to, and the other end is connected to type chamber, and the sectional area of the glue-feeder is gradually reduced from runner one end to type chamber one end,
The injecting hole leans on plesiotype chamber side.Injecting hole leans on plesiotype chamber side, can to stay in and connect in cow glue powder with product
Remaining sizing material is small as far as possible, in order to extract out from cow glue powder.
Further, when male die core and cow glue powder are separate structure, there is boss 211 on the male die core, it is described
There is recess 223, when the cow glue powder is placed on the male die core, the recess 223 is fastened on described convex on runner 221
On platform 211, cow glue powder is positioned and installed on male die core to facilitate.
Preferably, the injecting hole is connect by pipeline with gas source, has pressure-control valve, the gas source on the pipeline
For source nitrogen.Pressure in the adjustable injecting hole of pressure-control valve, while as gas source, it has chemically using source nitrogen
The advantages that matter is stablized, nontoxic easily collecting.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
