Abstract
The utility model discloses a scraper ledge casting mould without the pattern draft at the two ends. The scraper ledge casting mould comprises an upper die and a lower die, wherein scraper ledge cavities are formed in the upper die and the lower die; the upper die comprises an upper die intermediate body as well as a convex-end M-shaped moving block and a concave-end M-shaped moving block which are arranged at the two ends of the upper die intermediate body; and the bottom angles alpha 2 of the end surfaces of the convex-end M-shaped moving block and the concave-end M-shaped moving block are both right angles. The scraper ledge casting mould has the advantages as follows: the moving blocks without the pattern draft are arranged at the two ends of the mould, so that unnecessary waste caused by processing is reduced and the cost of a company is reduced; a scraper ledge is cast by the scraper ledge casting mould, so that the assembly gap of a complete machine, the processing steps and the processing cost of the company are reduced; and the two end surfaces of the scraper ledge produced by adopting the mould with the moving blocks without the pattern draft at the two ends of the upper die are also not inclined, and the butting gap between two workpieces is not more than 2 mm after the complete machine is assembled and butted, so that the drawing design requirement is met and the assembly quality and the appearance of the complete machine are improved.
Description
Technical field
The utility model mold belongs to a kind of two ends without the scrapper conveyor ledge mold of pattern draft, relate in particular to and a kind ofly realize not allowing pattern draft with loose piece, after final assembly, butt-joint clearance obviously is decreased in 2mm, meet Design Requirement Drawing, improve final assembly quality and aesthetic property.
Background technology
The molding gradient all is with at the scrapper conveyor ledge two ends that produce due to original method traditionally, be that punch end face base angle is the obtuse angle, after final assembly, every two joint gaps are larger, final assembly quality and aesthetic property have been affected, or two ends process after having added processing capacity, bring very large difficulty to company's processing, caused the significant wastage of manpower and materials.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency the scrapper conveyor ledge mold of a kind of two ends without pattern draft is provided, and loose piece is adopted at two ends, reduces unnecessary waste, reduces costs minimizing manufacturing procedure, low company cost expense.
For achieving the above object, the utility model is by the following technical solutions:
A kind of two ends comprise upper die and lower die without the scrapper conveyor ledge mold of pattern draft, and scrapper conveyor ledge die cavity is located in upper die and lower die, and patrix comprises the patrix intermediate and is arranged on nose M type loose piece and the recessed end M type loose piece at patrix intermediate two ends.
Above-mentioned two ends are without the scrapper conveyor ledge mold of pattern draft, and the end face base angle a2 of recessed end M type loose piece and nose M type loose piece is the right angle.
Above-mentioned two ends are without the scrapper conveyor ledge mold of pattern draft, described scrapper conveyor ledge die cavity comprises patrix intermediate, nose M type loose piece and recessed end M type loose piece, patrix intermediate, nose M type loose piece and recessed end M type loose piece all are arranged in the patrix sandbox, and counterdie groove die cavity is arranged in the counterdie sandbox.
Adopt technique scheme, the utility model has following advantage: two ends adopt loose piece not put pattern draft, reduce the unnecessary waste that processing causes, and have reduced the company cost expense.And the scrapper conveyor ledge that the utility model is cast out reduces the final assembly gap, reduces manufacturing procedure, reduces company's processing charges and cost.Employing patrix two ends are not with the loose piece mould of molding gradient, and the scrapper conveyor ledge both ends of the surface of producing are not with gradient yet, and after the final assembly docking, the butt-joint clearance≤2mm between two workpiece meets Design Requirement Drawing, improves final assembly quality and aesthetic property.

The specific embodiment
A kind of two ends as shown in Fig. 6-8 are without the scrapper conveyor ledge mold of pattern draft, comprise patrix 1 and counterdie 2, scrapper conveyor ledge die cavity is located in patrix 1 and counterdie 2, patrix 1 comprises the patrix intermediate and is arranged on nose M type loose piece 3 and the recessed end M type loose piece 4 at patrix intermediate two ends, the end face base angle a2 of recessed end M type loose piece 4 and nose M type loose piece 3 is the right angle, and namely two ends are without pattern draft.Scrapper conveyor ledge die cavity of the present utility model comprises patrix intermediate, nose M type loose piece 3 and recessed end M type loose piece 4, and patrix intermediate, nose M type loose piece 3 and recessed end M type loose piece 4 all are arranged in the patrix sandbox, and counterdie groove die cavity is arranged in the counterdie sandbox.
The scrapper conveyor ledge assembling that the utility model is cast out is as shown in Fig. 9-11, after two scrapper conveyor ledge workpiece 5 final assembly docking, butt-joint clearance L2 between two workpiece is significantly less than the butt-joint clearance L1 between traditional two workpiece 6, gap L 1 〉=8mm between tradition two workpiece 6, the butt-joint clearance L2≤2mm between two workpiece that the utility model is cast out.
