Abstract
The utility model discloses a round tube extrusion die comprising a male die and a female die, wherein the middle of the male die is provided with a feeding cavity; the middle of the feeding cavity is provided with an extrusion bar; the head of the extrusion bar is protruded forwards to form a male head and extends into the cavity of the female cavity; the inner diameter of the cavity of the female die is a first work zone which forms the outer diameter of the extruded round tube; the outer diameter of the male head of the male die is a second work zone which forms the inner diameter of the extruded round tube; and the top end of the second work zone is also provided with a stair-shaped empty cutter location. In the utility model, when the die is assembled or detached, the male head dose not collide with real articles around easily and the product is ensured; even though collision occurs, the direct damage is at the empty cutter location, therefore the working condition of the second work zone is not influenced directly, so that the quality of the product in production is ensured, the rate of finished products is improved, the reject ratio is lowered, the repair time of die technical personnel is saved, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of press molds, especially relates to a kind of press molds of pipe, belongs to mould design and processing technique field.
Background technology
Traditional pipe press molds, comprise male model and master mold, wherein, the centre of male model is the pan feeding cavity, the centre of pan feeding cavity then is a pressure ram, and the head of pressure ram protrudes the formation male forward, and is deep in the die cavity of master mold, in addition, the die cavity internal diameter of master mold is first work zone, and its formation extrudes the external diameter of pipe, and the male external diameter of male model then is second work zone, its formation extrudes the internal diameter of pipe, the top of the second above-mentioned work zone does not have the sky cutter spacing, this kind structure, in process of production, when assembling or dismounting mould, material object around male is easy to collide, second work zone are easy to distortion, even produce breach, and breach is easy to be filled by impurity in the raw material aluminium ingot or aluminium oxide, cut must appear in the pipe material inwall that causes extruding out, thereby causes the bad of product, and needs mould is changed or it is repaired after this kind situation takes place, not only need to spend great amount of manpower and time, but also greatly reduce production efficiency.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is a kind of efficient height, and can effectively guarantee the yield rate of product, the pipe press molds of saving cost.
The utility model is achieved through the following technical solutions:
A kind of pipe press molds comprises male model and master mold, wherein, the centre of male model is the pan feeding cavity, and the centre of pan feeding cavity then is a pressure ram, and the head of pressure ram protrudes the formation male forward, and be deep in the die cavity of master mold, in addition, the die cavity internal diameter of master mold is first work zone, and its formation extrudes the external diameter of pipe, the male external diameter of male model then is second work zone, its formation extrudes the internal diameter of pipe, it is characterized in that, the top of described second work zone also is provided with step-like empty cutter spacing.
Above-mentioned empty cutter spacing and outer wall male are at a distance of 2mm.
The beneficial effects of the utility model are: the utility model is provided with the sky cutter spacing by the top of second work zone on male, when making assembling or dismounting mould, material object around male is not easy to collide has guaranteed product surface quality, even it is directly impaired also at empty cutter spacing place collision phenomenon to occur, thereby can directly not have influence on the working condition of second work zone, the quality of the feasible product of producing is protected, improved yield rate, reduced fraction defective, also reduce mould personnel's repair time, improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Main Reference numeral implication is among the figure:
1, master mold 2, male model 3, second work zone 4, first work zone

The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of the present utility model in detail:
Fig. 1 is the structural representation of the utility model one embodiment; Fig. 2 is the A portion enlarged drawing of Fig. 1.
As illustrated in fig. 1 and 2: the pipe press molds, comprise male model 2 and master mold 1, wherein, the centre of male model 2 is the pan feeding cavity, the centre of pan feeding cavity then is a pressure ram 6, the head of pressure ram 6 protrudes the formation male forward, and be deep in the die cavity of master mold 1, in addition, the die cavity internal diameter of master mold 1 is first work zone 4, and its formation extrudes the external diameter of pipe, the male external diameter of male model 2 then is second work zone 3, its formation extrudes the internal diameter of pipe, and the top of described second work zone 3 also is provided with step-like empty cutter spacing 5, and the outer wall of empty cutter spacing 5 and male is at a distance of 2mm.
The utility model is provided with sky cutter spacing 5 by the top of second work zone on male, when making assembling or dismounting mould, material object around male is not easy to collide has guaranteed product surface quality, even it is directly impaired also at empty cutter spacing 5 places collision phenomenon to occur, thereby can directly not have influence on the working condition of second work zone 3, the quality of the feasible product of producing is protected, improved yield rate, reduce fraction defective, also reduced mould personnel's repair time, improved production efficiency.
Below disclose the utility model with preferred embodiment, so it is not in order to restriction the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode is obtained, all drops within the protection domain of the present utility model.
Claims (2)
1. a pipe press molds comprises male model and master mold, wherein, the centre of male model is the pan feeding cavity, and the centre of pan feeding cavity then is a pressure ram, and the head of pressure ram protrudes the formation male forward, and be deep in the die cavity of master mold, in addition, the die cavity internal diameter of master mold is first work zone, and its formation extrudes the external diameter of pipe, the male external diameter of male model then is second work zone, its formation extrudes the internal diameter of pipe, it is characterized in that, the top of described second work zone also is provided with step-like empty cutter spacing.
