Description

Forming tool for eliminating closed angle of molded part

Technical Field

The utility model belongs to the combined material field, concretely relates to eliminate shaping frock at mould pressing piece closed angle.

Background

After the existing mould pressing piece is solidified and formed by a hot press to obtain a part, an auxiliary tool stop block in the mould pressing piece needs to be pulled out.

However, fig. 1 is a schematic external view of a conventional molded part, and as shown in fig. 1, the cross section of the molded part is a U shape with a closed end, and the three inner surfaces of the molded part may be provided with depressions in different directions, respectively, so that the stop block of the auxiliary tool is difficult to separate from the part when the stop block is withdrawn from any direction, and the part is damaged during the demolding process of the auxiliary tool.

SUMMERY OF THE UTILITY MODEL

The utility model provides an eliminate shaping frock of moulded piece closed angle solves the problem that current moulded piece drawing of patterns in-process probably harm.

The utility model provides an eliminate shaping frock of moulded piece closed angle, include: the device comprises a base, an upper die 1, a first middle die block 2, a second middle die block 3, a left stop block 4, a lower die 5 and a right stop block 6; wherein,

the base, the upper die 1, the left stop block 4, the lower die 5 and the right stop block 6 are attached to the outer surface of the die pressing piece;

the first middle die block 2 and the second middle die block 3 form a middle die block which is attached to the inner surface of the die pressing piece and is attached to the upper die 1, the left stop block 4, the lower die 5 and the right stop block 6;

the angle that the binding face of module 2 in the first module 2 with in the second module 3 and the bottom surface of mould pressing piece was is not more than the angle that the binding face of module 2 in the first with the mould pressing piece with the bottom surface of mould pressing piece was, the binding face of module 2 in the first module 2 with in the second module 3 is the plane.

Optionally, the abutting surfaces of the first middle module 2 and the die pressing piece are parallel to the abutting surfaces of the first middle module 2 and the second middle module 3.

Optionally, a lifting ring screw hole for mounting a lifting ring is formed in the first middle module 2.

Optionally, the forming tool for eliminating the closed angle of the die pressing piece further comprises: a pin 7 and a screw 8; wherein,

the first middle module 2 and the second middle module 3 are fixedly connected through pins and screws.

Optionally, a die opening groove is formed in the joint surface of the first middle die block 2 and the second middle die block 3.

Optionally, the upper die 1 and the lower die 5 are provided with glue flowing grooves.

The utility model provides an eliminate shaping frock at moulded piece closed angle through being divided into two with traditional well module, and the parting line face between the two well modules of simultaneous design is the inclined plane, and the parting line face cross-section of module 2 is little for the lower extreme in the first, and the upper end is big, and the parting line face cross-section of module 3 is big for the lower extreme in the second, and the upper end is little. After the part is formed, the purpose of demoulding is achieved by obliquely hanging the first middle module 2 through the hanging ring.

Detailed Description

The following explains the forming tool for eliminating the closed angle of the molded part according to the present invention with reference to the accompanying drawings.

Referring to fig. 2-5, the utility model provides an eliminate shaping frock of moulded piece closed angle includes: go up mould 1, first module 2, module 3, left dog 4, lower mould 5, right dog 6 in the second, pin 7, screw 8 and base.

The utility model discloses a be divided into two with traditional well module, the parting line face between the two well modules of simultaneous design is the inclined plane, and the parting line face cross-section of module 2 is little for the lower extreme in the first, and the upper end is big, and the parting line face cross-section of module 3 is big for the lower extreme in the second, and the upper end is little. After the molding press 9 is formed, the purpose of demolding is achieved by obliquely hanging the first middle module 2 through the hanging ring.

Further, the first middle module 2 is connected with the second middle module 3 through a pin 7, a screw 8 is fixed, and meanwhile, an area for avoiding the pin 7 and the screw 8 is formed in the upper end of the first middle module 2.

Further, mold opening grooves are formed in the mold splitting surfaces of the first middle mold block 3 and the second middle mold block 4, mold opening is facilitated, and the number of the mold opening grooves is determined according to the lengths of the first middle mold block 3 and the second middle mold block 4.

Further, a lifting ring screw hole is formed in the side face of the first middle module 3, and in the mold taking process, the first middle module 3 is taken out by the hanging device.

Furthermore, the left block 4 and the right block 6 are fixed on the lower die 4 from the side through screws 7 and pins 8.

Furthermore, glue flowing grooves are formed in the upper die 1 and the lower die 5, so that glue is conveniently removed after the upper die is taken out.
