Technical Field

The utility model relates to a spiral stirring vane's die mould. Belongs to the technical field of machinery.

Background

The existing spiral stirring blades used on equipment such as a conveyor, a stirrer, an extruder and the like are mostly formed by casting, and the method has high cost; the prior art has a corresponding profiling mold, the structure is complex, and large-batch profiling output cannot be realized.

The chinese utility model patent (application No. 201721580319.1) discloses an upper pressure film and a lower pressure film, all be provided with helical curved surface a helical blade moulding-die on upper pressure film and the lower pressure film, upper pressure film and lower pressure film, all be provided with helical curved surface on upper pressure film and the lower pressure film.

The above patent has the following problems: the upper pressing film and the lower pressing film are both provided with spiral curved surfaces corresponding to the shapes of the spiral blades, the processing difficulty of the spiral curved surfaces is large (the die opening difficulty is large), the structure is complex, and batch production cannot be realized.

Disclosure of Invention

An object of the utility model is to overcome above-mentioned not enough, provide a helical mixing blade's die mould utensil.

The purpose of the utility model is realized like this:

the utility model provides a helical mixing blade's die mould which its characteristics are: it is including the last mould and the lower mould that the symmetry was used, goes up the mould and is the same with lower die structure, and the lower mould includes base plate, left board, medium plate, right board and protective sheath, and the contained angle of left board and medium plate equals the contained angle of right board and medium plate, and the top surface of medium plate is straight face, and the top surface of left board and right board is the inclined plane, and the incline direction on two inclined planes is opposite, and inclination is the same.

Spiral stirring vane's die mould still includes three protective sheath, and three protective sheath sets up respectively at the top of left board, medium plate and right board, and the top surface of protective sheath is the cylinder, the top surface of protective sheath with treat the panel cooperation of die mould.

Further, the included angle between the left plate and the middle plate is 15 degrees.

Further, left board 2 and right board 4 all are trapezoidal, and medium plate 3 is square.

Further, the bottom of protective sheath is opened flutedly, and the recess is square groove, and the top of left board, medium plate and right board is fixed respectively and is set up in the recess of three protective sheath.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model relates to a spiral stirring vane's die mould, the preparation of upper and lower mould symmetry is used, and panel setting is at last, between the bed die, goes up the mould and gives certain pressure to press into required spiral stirring vane's shape with panel, the protective sheath can prevent effectively that panel is impaired when the die mould, the utility model discloses simple structure, the operation degree of difficulty is low, can realize mass production.

Detailed Description

Referring to fig. 1-5, the utility model relates to a helical mixing blade's die mould, it includes the last mould and the lower mould that the symmetry was used, goes up the mould the same with lower mould structure, uses the lower mould as an example, the lower mould includes base plate 1, left board 2, medium plate 3, right board 4 and protective sheath 5, left side board 2 equals the contained angle beta of right board 4 and medium plate 3 with the contained angle alpha of medium plate 3, the top surface of medium plate 3 is flat plane, and the top surface of left board 2 and right board 4 is the inclined plane, and the incline direction on two inclined planes is opposite, and inclination is the same, and the top surface of left board 2, medium plate 3 and right board 4 corresponds with helical mixing blade shape to extrusion helical mixing blade.

The included angle alpha and the included angle beta are both 15 degrees.

Left board 2 and right board 4 all are trapezoidal, and medium plate 3 is square.

Protective sheath 5 has threely, and protective sheath 5 sets up respectively at the top of left board 2, medium plate 3 and right board 4, and protective sheath 5's top surface is the cylinder, and open protective sheath 5's bottom has the recess, and the recess is square groove, and left board 2, medium plate 3 and right board 4's top is fixed respectively and is set up in three protective sheath 5's recess.

The working principle is as follows: as shown in fig. 4-5, the upper and lower molds are symmetrically manufactured and used, the plate is disposed between the upper and lower molds, and the upper mold applies a certain pressure to press the plate into a single piece of the required helical stirring blade (see fig. 6), the cylindrical surface of the protective sleeve 5 can effectively prevent the plate from being damaged during pressing, and the helical stirring blade (see fig. 7) is formed by combining a plurality of pressed single pieces.
