Abstract
The invention discloses a neck forming die for a filter housing cover. The neck forming die comprises an upper die, a middle die and a lower die, wherein guide rods are installed on the lower die; the middle die and the upper die are glidingly installed on the guide rods; springs sleeved on the guide rods are respectively connected between the upper die and the middle die as well as between the middle die and the lower die; a cylindrical part is arranged in the middle of the middle die, a supporting block is arranged in a cylindrical cavity of the cylindrical part, and four through holes are arranged in the outer wall of the cylindrical part adjacent to a cylindrical opening at the front end of the cylindrical part of the middle die; a semicircular groove is respectively formed in the middle of the upper die and the middle of the lower die, and pressure levers are arranged in the semicircular grooves of the upper die and the lower die; the upper die and the lower die are respectively positioned at the upper and the lower pars of the middle die; and the pressure levers of the upper die and the lower die respectively penetrate through the through holes of the cylindrical part of the middle die. According to the neck forming die disclosed by the invention, with the mutually compressed structure of the upper die, the lower die and the middle die, the cross section of the reduced neck of the housing cover can be ensured to be strictly perpendicular to an axis in the center of the housing cover, the reduced neck of the housing cover has better flatness, and the product quality of the filter housing cover is improved.
Description
Technical field
The present invention relates to filter process units field, be specially a kind of neck forming die for filter housing cover.
Background technology
Filter is indispensable a kind of device on pumped (conveying) medium pipeline, and its effect is the impurity of eliminating in the medium of the filter of flowing through.Filter comprises case, in case, by central support tube, supports filter screen, by filter screen, plays the filtration to medium.Case need to be shaped to neck the neck of undergauge, with spacing central support tube, the case neck shaping mould of prior art adopts drift to carry out punching press mostly, case neck out-of-flatness after undergauge moulding, and case undergauge neck cross section and case central shaft relative tilt rather than vertical relation, cause filter case to occur substandard products.
Summary of the invention
The object of the invention is to provide a kind of neck forming die for filter housing cover, easily causes the problem of substandard products to solve prior art neck forming die for filter housing cover.
In order to achieve the above object, the technical solution adopted in the present invention is:
Neck forming die for filter housing cover, comprise the patrix that is respectively rectangle, middle mould, counterdie, it is characterized in that: described counterdie corner location is separately installed with vertical guide rod, described middle mould, patrix is slidably mounted on respectively on the guide rod of counterdie successively, and between patrix and middle mould, between middle mould and counterdie, be connected with respectively the spring being enclosed within on guide rod, in the middle of described middle mould, there is cylindrical part, in the cylinder chamber of middle mould cylindrical part, be provided with the columned back-up block parallel with cylindrical part, from close, the middle mould cylindrical part outer wall of mould cylindrical part front end nozzle has four through holes to cylindrical part inwall, and four through holes are arranged on the circumference in the same mould cylindrical part cross section around back-up block, described patrix, in the middle of counterdie, form respectively in corresponding and middle mould cylindrical part, the half slot of lower tubular face coupling, and patrix, in the half slot of counterdie, in correspondence, mould cylindrical part lead to the hole site is respectively arranged with depression bar, described patrix, counterdie lays respectively on middle mould, bottom, patrix, the depression bar of counterdie stretches into respectively in through hole corresponding to middle mould cylindrical part position.
Described neck forming die for filter housing cover, is characterized in that: described middle mould cylindrical part rear end tube port position is provided with support bar, and described back-up block rear end is bolted on support bar.
The present invention includes patrix, middle mould, counterdie, patrix, middle mould are slidably mounted on respectively on the guide rod on counterdie, and upper die and lower die lay respectively at the upper and lower of middle mould.During use, the case for the treatment of undergauge is enclosed within to the outer and case of the back-up block of middle mould between back-up block and middle mould cylindrical part inwall, and make case neck to be contracted corresponding with position, middle mould cylindrical part through hole aperture, then press down patrix, by patrix, middle mould is pressed down, mould in finally jointly clamping to upper die and lower die.In the process pressing down at patrix, depression bar on patrix slides and stretches in middle mould cylindrical part in the corresponding through hole of middle mould cylindrical part, finally support at case neck, in the process pressing down at middle mould, depression bar on counterdie slides and stretches in middle mould cylindrical part in the corresponding through hole of middle mould cylindrical part, finally also support at case neck, by upper die and lower die, middle mould are pressed against each other, then rotate case, utilize the rod end of push rod case neck can be shaped to the neck of undergauge, after moulding completes, patrix, middle mould, counterdie are realized and being resetted by the spring connecting each other.The structure that the present invention is pressed against each other by upper die and lower die, middle mould, can guarantee that the case neck cross section after undergauge is strictly vertical with case central axis, and make the neck of case undergauge have good planarization, has improved the quality of production of filter case.
