Description

Demolding structure with internal thread product

[technical field]

The utility model relates to a kind of demolding structure, is specifically related to a kind of demolding structure with internal thread product.

[background technology]

When production had the product of internal thread, when adopting mould that it is carried out moulding, product stripping can become problem.

See also Fig. 1, Fig. 1 illustrates a kind of demolding structure with internal thread product for prior art.Described product 100 has internal thread 101.Described demolding structure has interconnective motor 102, gear 103 and screw mandrel 104, the end of described screw mandrel 104 cooperates the internal thread 101 of shaped article 100, after described product 100 moulding, described motor 102 drives described gear 103, described gear 103 drives described screw mandrel 104 rotations again and breaks away from the internal thread 101 of described product 100, and then reaches the purpose of the demoulding.

Yet, adopt above-mentioned demolding structure with internal thread 101 products 100, owing to needing motor 102 gears 103 equipment such as grade, its manufacturing expense is high, takes up room large.

In view of this, be necessary to provide a kind of demolding structure with internal thread product in fact, to address the above problem.

[summary of the invention]

Therefore, the purpose of this utility model provides a kind of demolding structure with internal thread product, solves to have that internal thread product stripping infrastructure cost is high, large problem takes up room.

In order to achieve the above object, the demolding structure with internal thread product of the present utility model, this demolding structure is used for mould, and described mould has male die core, mother module core, and this demolding structure comprises:

The bundle piece is fixed on the described mother module core, and the both sides of described bundle piece have slide rail;

Two inner slides are located in the described male die core relatively, and described inner slide one side has chute, is installed with the described slide rail of described bundle piece in the described chute, and described inner slide has the inner slide forming surface away from described chute one side, and described inner slide bottom has guide groove;

Two taper pins are located in the pin hole of described male die core relatively, and described taper pin top has the taper pin forming surface, and described taper pin forming surface cooperates the described internal thread of the described product of moulding with described inner slide forming surface;

Guide rail is located in the described male die core, cooperates with the described guide groove of described inner slide.

Optionally, described bundle piece upper end is wide than the lower end.

Optionally, described slide rail is T-shaped, and described chute corresponds to T-shaped.

Optionally, described slide rail is dove-tail form, and described chute corresponds to dove-tail form.

Optionally, described guide rail is T-shaped, and described guide groove corresponds to T-shaped.

Optionally, described guide rail is dove-tail form, and described guide groove corresponds to dove-tail form.

Compared to prior art, demolding structure with internal thread product of the present utility model, during die sinking, described bundle piece drives described inner slide and inwardly moves, and then breaking away from the described internal thread of described product, described taper pin ejects described product and break away from the described internal thread of described product afterwards.Owing to adopting described inner slide and described taper pin can reach the described internal thread that breaks away from described product, thereby need not the equipment such as motor gear, its manufacturing expense is low, takes up room little.

[specific embodiment]

See also Fig. 2, Fig. 2 illustrates a kind of structural representation with product of internal thread.As shown in the figure, described product 200 has internal thread 201.

Please consult Fig. 3, Fig. 3 illustrates the stereochemical structure decomposing schematic representation into demolding structure one preferred embodiment of internal thread product of the present utility model again.

In order to achieve the above object, the demolding structure with internal thread product of the present utility model is in order to the product with internal thread 201 200 shown in the production drawing 2, this demolding structure is used for mould, described mould has male die core 202, mother module core 203, and in the present embodiment, this demolding structure comprises:

Bundle piece 204 is fixed on the described mother module core 203, and the both sides of described bundle piece 204 have slide rail 205;

Two inner slides 206, relatively be located in the described male die core 202, described inner slide 206 1 sides have chute 207, be installed with the described slide rail 205 of described bundle piece 204 in the described chute 207, described inner slide 206 has inner slide forming surface 208 away from described chute 207 1 sides, and described inner slide 206 bottoms have guide groove 209;

Two taper pins 210 are located in the pin hole 211 of described male die core 202 relatively, and described taper pin 210 tops have taper pin forming surface 212, and described taper pin forming surface 212 cooperates the described internal thread 201 of the described product 200 of moulding with described inner slide forming surface 208;

Guide rail 213 is located in the described male die core 202, cooperates with the described guide groove 209 of described inner slide 206.

Wherein, described bundle piece 204 upper ends are wide than the lower end, thereby can take described inner slide 206 inwardly move (two inner slide 206 move toward one another) to.

Wherein, in the present embodiment, described slide rail 205 is T-shaped, and described chute 207 corresponds to T-shaped; Certainly, described slide rail 205 also can be dove-tail form, and described chute 207 also can correspond to dove-tail form.

Wherein, in the present embodiment, described guide rail 213 is T-shaped, and described guide groove 209 corresponds to T-shaped; Certainly, described guide rail 213 also can be dove-tail form, and described guide groove 209 also can correspond to dove-tail form.

Please in conjunction with consulting Fig. 4, Fig. 5, Fig. 4 illustrates matched moulds view, Fig. 5 for demolding structure one preferred embodiment of internal thread product of the present utility model and illustrates the first die opening state (inner slide disengaging) schematic diagram into demolding structure one preferred embodiment of internal thread product of the present utility model.

During die sinking, because the described slide rail 205 of described bundle piece 204 is the inclined plane, the described chute 207 of the described inner slide 206 that cooperates with it also is the inclined plane, described bundle piece 204 drives described inner slide 206 and inwardly moves (guide groove 209 limited can only the moving at described guide rail 213 of described inner slide 206), and then breaks away from the described internal thread 201 of described product 200.

Please consult Fig. 6, Fig. 6 illustrates the second die opening state (angle pin ejecting) schematic diagram into demolding structure one preferred embodiment of internal thread product of the present utility model again.Fig. 6 and Fig. 5 to analyse and observe direction orthogonal.

Hold, after described inner slide 206 breaks away from the described internal thread 201 of described product 200, continue die sinking, described taper pin 210 is subject to described pin hole 211 and moves upward, because described taper pin 210 also is inclination, therefore shrink at its top, and then also break away from the described internal thread 201 of described product 200 when described product 200 is ejected.

To sum up, owing to adopting described inner slide 206 and described taper pin 210 can reach the described internal thread 201 that breaks away from described product 200, thereby need not the equipment such as motor 102 gears 103, its manufacturing expense is low, takes up room little.
