When using said three board mold injection mouldings; Earlier said upper mounted plate, stripper plate, caster and mother module core are compressed successively each other, the injection raw material with fusion injects condensation moulding in said stub bar passage afterwards from the said inlet that waters again; Formed product is in said mother module core; Form stub bar in the stub bar passage, at last said upper mounted plate, stripper plate and caster are separated from each other, and adopt manipulator or artificial mode that said stub bar is taken out from said stripper plate.Make whole process of production can't realize whole-course automation like this, and make production efficiency low.
The utility model content
The purpose of the utility model is to the deficiency of above-mentioned prior art a kind of three board molds to be provided; Said three board molds are after accomplishing injection moulding; Stub bar can automatically come off from stripper plate; Needn't adopt manipulator or artificial mode, realize the whole-course automation of whole process of production, and improved production efficiency.
For realizing above-mentioned purpose; The utility model provides a kind of three board molds, comprises upper mounted plate, stripper plate, caster and mother module core, and said stripper plate is located between said upper mounted plate and the caster; Said mother module core is arranged in the said caster; Said upper mounted plate is provided with and waters inlet, and one draws the material pin to be arranged at saidly waters inlet and insert said stripper plate, and said caster and mother module core are provided with and the said stub bar passage that is used for the stub bar cast molding that enters the mouth and be connected that waters.Wherein, said three board molds also comprise an elastic component and a bullet piece that is arranged at said stripper plate, and an end of said elastic component is installed on said stripper plate, the other end of the said elastic component said bullet piece of conflicting, the said bullet piece said stub bar of conflicting after the condensation moulding.
Further, said stripper plate has an installation portion, and an end of said elastic component is installed on said installation portion.
Further, said elastic component is a wire spring.
As stated, three board molds of the utility model comprise an elastic component and a bullet piece that is arranged at said stripper plate, and an end of said elastic component is installed on said stripper plate, the other end of the said elastic component said bullet piece of conflicting, the said bullet piece said stub bar of conflicting; After accomplishing injection moulding, said elastic component produces outside elastic force, and makes stub bar break away from said stripper plate through said bullet piece, needn't adopt manipulator or artificial mode, has realized the whole-course automation of whole process of production, and has improved production efficiency.

The specific embodiment
By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.
See also Fig. 1 and Fig. 2; The utility model three board molds comprise upper mounted plate 10, stripper plate 12, elastic component 16, bullet piece 18, caster 22 and mother module core 24; Said stripper plate 12 is located between said upper mounted plate 10 and the caster 22; One end of said elastic component 16 is installed on said stripper plate 12, the other end of the said elastic component 16 said bullet piece 18 of conflicting, and said mother module core 24 is arranged in the said caster 22.Said upper mounted plate 10 is provided with and waters inlet 101; One draws material pin 14 to be arranged at saidly waters inlet 101 and inserts said stripper plate 12; Said caster 22 is provided with said with mother module core 24 and waters the stub bar passage 201 that is used for stub bar 20 cast moldings that inlet 101 is connected, and the said stub bar 20 of said bullet piece 18 conflicts after the condensation moulding.
Particularly, said stripper plate 12 has an installation portion 121, and an end of said elastic component 16 is installed on said installation portion 121.
Preferably, said elastic component 16 is a wire spring.
See also Fig. 3 to Fig. 7 again, said stub bar 20 breaks away from the process of said stripper plate 12 automatically after having described the three board molds casting product that uses the utility model and having accomplished the casting injection moulding.
As shown in Figure 3; When using said three board molds, earlier said upper mounted plate 10, stripper plate 12, caster 22 and mother module core 24 are compressed successively each other, the injection raw material with fusion injects from the said inlet 101 that waters again; After the condensation moulding; Product 30 takes shape in the said mother module core 24, the said stub bar 20 of condensation moulding in the said stub bar passage 201, thus accomplish whole injection moulding process.
Afterwards, carry out the die sinking operation.As shown in Figure 4; Earlier said stub bar 20 is separated with product 30; This moment, said stub bar 20 was pulled away said stub bar passage 201, and said stub bar 20 is attached to said stripper plate 12 said drawing under the effect of expecting pin 14, and said stub bar 20 can receive the outside elastic force that comes from said elastic component 16.But because the said elastic force that draws the pulling force of material pin 14 greater than said elastic component 16, therefore, said elastic component 16 and bullet piece 18 can't outwards eject said stub bar 20, and this moment, said elastic component 16 was in compressive state.
Then; Like Fig. 5, shown in Figure 6; The said material pin 14 that draws is separated with said stub bar 20, and this moment, compressed said elastic component 16 outwards ejected said stub bar 20 through said bullet piece 18, made it break away from said stripper plate 12; Reach state as shown in Figure 7, thereby accomplish the process that said stub bar 20 breaks away from said stripper plate 12 automatically.
As stated; Because three board molds of utility model comprise an elastic component 16 and a bullet piece 18 that is arranged at said stripper plate 12; One end of said elastic component 16 is installed on said stripper plate 12, the other end that said elasticity is 16 the said bullet piece 18 of conflicting, the said bullet piece 18 said stub bar 20 of conflicting; After accomplishing injection moulding, said elastic component 16 produces outside elastic force, and makes stub bar 20 break away from said stripper plate 12 through said bullet piece 18, needn't adopt manipulator or artificial mode, has realized the whole-course automation of whole process of production, and has improved production efficiency.
