Abstract
The utility model provides a high-pressure casting die for a stepped end face structure, which is used for solving the problems of difficult breath holding and difficult removal and easy gas wrapping defect of a stepped casting piece.
Description
Technical Field
The utility model relates to the technical field of dies, in particular to a high-pressure casting die for a stepped end face structure.
Background
Pressure casting is a casting process in which a liquid or semi-solid metal or alloy, or a liquid metal or alloy containing a reinforcement phase, is filled into a cavity of a die casting mold at a relatively high rate under high pressure, and the metal or alloy is solidified under pressure to form a casting.
In high-pressure casting, a conventional slag ladle exhaust structure is used, so that the gas hold in the range of 5mm of the area where the slag ladle is located can be removed only for the stepped structure, and the gas hold formed at the step is difficult to remove, so that the gas hold defect is caused.
Disclosure of Invention
In order to solve the problems of difficult breath holding and removal and easy gas wrapping defect of a stepped casting part, the utility model provides a high-pressure casting die for a stepped end face structure, which adopts the following technical scheme:
the utility model provides a high-pressure casting mould for echelonment terminal surface structure, its characterized in that includes upper die base, die holder, the shaping has the ladder chamber between upper die base die cavity and the die holder die cavity, be provided with first circular arc groove on the upper die base die cavity, first circular arc groove distributes in ladder chamber outer end top along ladder chamber circumferencial direction to first circular arc groove and ladder chamber intercommunication, be provided with on the die holder die cavity and be located ladder chamber below and be linked together with the ladder chamber second circular arc groove.
Preferably, the first arc grooves are provided with a plurality of groups, the plurality of groups of first arc grooves are distributed at intervals in the radial direction of the step cavity, and the plurality of groups of first arc grooves are distributed in a crossed manner in the circumferential direction of the step cavity.
Preferably, the heights of the first arc groove and the second arc groove are not smaller than the height of the step cavity.
Preferably, the edges of the first circular arc groove and the second circular arc groove are provided with round corners
The utility model has the beneficial effects that: through setting up first circular arc groove, can effectively get rid of holding breath that echelonment flange structure ladder department produced, the second circular arc groove can get rid of holding breath that the long section of thick bamboo end of echelonment flange produced, through being provided with the first circular arc groove of multiunit in the different radial positions in ladder chamber moreover, can further improve the exhaust effect that ladder department held breath, avoid the narrow and small region in ladder department corner to hold breath and be difficult to the discharge when casting.

The device comprises a 1-lower die holder, a 2-upper die holder, a 3-lower die holder cavity, a 4-upper die holder cavity, a 5-step cavity, a 6-first circular arc groove, a 7-second circular arc groove, an 8-guide pillar, a 9-step end face degassing plate and a 10-long cylinder end face degassing plate.
Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In the description of the utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the view direction or positional relationships, merely to facilitate describing the utility model, and do not indicate or imply that the devices or elements being referred to must have a particular orientation, be configured and operated in a particular orientation, and thus should not be construed as limiting the utility model.
Taking the structure of the high-pressure casting mold of the rear end cover of the output shaft as an example, the high-pressure casting mold for the stepped end surface structure shown in fig. 1-5 comprises a lower mold base 1 and an upper mold base 2, wherein a lower mold base cavity 3 is arranged on the lower mold base 1, an upper mold base cavity 4 is arranged on the upper mold base 2, a stepped cavity 5 is formed between the lower mold base cavity 3 and the upper mold base cavity 4 in a matching mode, two groups of first circular arc grooves 6 communicated with the stepped cavity 5 are arranged at the lower end of the outer side of the upper mold base cavity 4, and are distributed at a certain distance in the radial direction of the stepped cavity 5, so that two groups of outer end surfaces at the upper end surface of the stepped cavity 5 are correspondingly distributed in a certain length in a superposition manner in the circumferential direction of the stepped cavity 5, the exhaust effect of the stepped position is improved under the condition that the integral weight of a part is not increased and the subsequent processing convenience is not affected is ensured, and a second circular arc groove 7 positioned below the stepped cavity 5 is arranged in the lower mold base cavity 3, and the second circular arc groove 7 is communicated with the stepped cavity 5.
In addition, in the present embodiment, the first and second circular arc grooves 5 and 7 are each the same in height as the stepped cavity 5, and rounded corners are provided at the edges.
The structure of the end cover of the output shaft formed by the die is shown in fig. 6, two groups of ladder end face degassing plates 9 distributed along the circumferential direction are formed at the flange end of the end cover, the two groups of ladder end face degassing plates 9 are distributed at a certain distance in the radial direction, and a long cylinder end of the end cover of the output shaft is formed with a long cylinder end face degassing plate 10.
Through the setting of first circular arc groove 6, can effectively solve the condition of holding breath of echelonment flange upper portion position, through the structure setting of second circular arc groove 7, can effectively solve long section of thick bamboo end upper portion problem of holding breath, set up two sets of first circular arc grooves 6 moreover, with two lateral surfaces at the ladder terminal surface corresponding distribution link to each other for with holding breath of ladder department in time discharge, further improve whole degassing effect.
The foregoing is only a preferred embodiment of the utility model, it being noted that: it will be apparent to those skilled in the art that modifications may be made without departing from the principles of the utility model, and such modifications are intended to be within the scope of the utility model.
