Abstract
The utility model discloses a positioning device for a sealing die of a round silencer. The positioning device comprises an anti-rotation accessory of the round silencer, and an accessory which is used for ensuring the relative position of an upper inner tube 3 and a lower inner tube 8 of the silencer. The positioning device has the beneficial effects that firstly, with an upper positioning pillar 2 and a lower positioning pillar 7, the installation positions of the silencer end covers and the silencer cylinder body on the sealing die are effectively ensured, which facilitates the down pressing of the sealing die; secondly, with the upper and the lower positioning pillars 2 and 7, the relative position of the upper inner tube 3 and the lower inner tube 8 of the silencer is effectively ensured, so that the positions of the upper inner tube 3 and the lower inner tube 8 in the silencer cylinder body 4 are not changed; and thirdly, with an upper die core 1 and a lower die core 6, the relative position of the upper end cover and the lower end cover of the silencer is effectively ensured, as a result, the working efficiency is greatly improved, and the rejection rate of the product is reduced.
Description
Technical field
The utility model relates to circular silencer seal mould positioner.
Background technology
Present circular silencer seal mould positioner is the elastic positioning device of making of rubber, and its problem one is to be unfavorable for silencer end cap and silencer cylinder putting on seal mould; The 2nd, be unfavorable for guaranteeing the silencer relative position of two end cap up and down; The 3rd, be unfavorable for guaranteeing the silencer relative position of interior pipe up and down.
Summary of the invention
The order ground of the utility model is to improve silencer to seal efficient, reduces the silencer percent defective.
The order ground of the utility model is realized through following mode: a kind of circular silencer seal mould positioner, comprise upper mold core 1, lower mold core 6, and be separately fixed at up and down on the seal mould; Last reference column 2, reference column 7 is fixed on upper mold core 1, the lower mold core 6 down; Upper end cover 9, bottom end cover 5 are enclosed within on the corresponding cylindrical shell 4, and cylindrical shell 4 and bottom end cover 5 are enclosed within down on the reference column 7, and upper end cover 9 is enclosed within on the reference column 2; To go up reference column 2 and insert upward interior pipe 3; It is characterized in that: said lower mold core 6 is provided with lower mold core counterbore 10, upper mold core is provided with upper mold core counterbore 11, and lower mold core counterbore 10 is aimed at bottom end cover 5 outer apertures, and reference column 7 is aimed at bottom end covers 5 internal orifice dimensions at present together; Upper mold core counterbore 11 is aimed at upper end cover 9 outer apertures, goes up reference column 2 simultaneously and aims at upper end cover 9 internal orifice dimensions.This structure has prevented the rotation that core rod is random.
The diameter range of said lower mold core counterbore 10, upper mold core counterbore 11, and depth bounds is according to the setting of bottom end cover 5, upper end cover 9 sizes, diameter range is than the monolateral big 0.7-1mm in end cap external diameter hole, and depth bounds is than the dark 3-5mm in end cap aperture.
The said diameter range of going up reference column 2 is than the monolateral little 0.5-0.6mm of upper end cover internal orifice dimension; Last reference column 2 stretch in the pipe 3 apart from 50-60mm; The diameter range of following reference column 7 is than the monolateral little 0.5-0.6mm of upper end cover internal orifice dimension, and pipe 8 was apart from 20-25mm in following reference column 2 stretched into down.
The utlity model has has beneficial effect as follows: the setting of seal mould positioner, one of which advantage are exactly to have made things convenient for silencer upper end cover 9, bottom end cover 5 and the riding position of silencer cylinder 4 on seal mould, the pressing down of easily sealing mould; Its two advantage is the relative position of pipe 3 in reference column has effectively guaranteed on the silencer, following interior pipe 8, and its position in silencer cylinder 4 can not be changed; Its three advantage is the relative position that core rod has effectively guaranteed silencer upper end cover 9, bottom end cover 5; More than three advantages improved operating efficiency greatly, reduced the scrappage of product.
Description of drawings
Fig. 1 is the utility model structural representation
On 1 upper mold core 2 on the reference column 3 in pipe 9 upper end covers 10 lower mold core counterbores 11 upper mold core counterbores in pipe 4 cylindrical shell 5 bottom end covers, 6 lower mold core 7 times reference columns 8 times.
The specific embodiment
As shown in Figure 1: that upper end cover 9, bottom end cover 5 are enclosed within on the corresponding cylindrical shell 4; Cylindrical shell 4 and bottom end cover 5 are enclosed within down on the positioner; Hole aligning above the bottom end cover 5 is reference column 7 down, capsuling machine is slowly moved down put in place, will go up in reference column 2 insertions upward and manage in 3; In effective like this assurance pipe 3 with down in the relative position and the perpendicularity of pipe 8 and upper end cover 9 and bottom end cover 5, can begin silencer with that to have sealed; Rotation along with sealing machine; Because upper end cover 9 is with bottom end cover 5 and go up reference column 2, the effect of reference column 7 down; Effectively prevented upper end cover 9, bottom end cover 5, go up in pipe 3, down in pipe 8, cylindrical shell 4 and assembly along with the sealing machine rotation, thereby pipe 3 in having guaranteed to go up, down in the relative position of pipe 8 in cylindrical shell 4.
