Abstract
The utility model discloses a locating and molding fixture for an oil sump sealing piece. The locating and molding fixture comprises a molding locating plate (10) and a plurality of locating columns (11), wherein the locating columns (11) are arranged on the molding locating plate (10); and the locating columns (11) correspond to machine mounting or locating holes (22) in the oil sump sealing piece (20) in position and shape. The heights of the locating columns (11) protruding out of the molding locating plate (10) are more than the thicknesses of the machine mounting or locating holes (22). Therefore, the accuracies of relative positions of the machine mounting or locating holes are guaranteed; meanwhile, the loss of a plastic framework rubber piece caused by product dislocation during mounting a machine is also eliminated.
Description
Technical field
The utility model relates to a kind of tool, especially relates to a kind of location moulding tool that is used for the plastic skeleton seal of automotive oil drain pan.
Background technology
The oil sump seal plays a part very important in automotive applications, phenomenon such as seal failure causes easily oozing, emits, drips, leakage, the serious performance that then has influence on whole part or even cause serious security incident; Increasing employing plastic skeleton waters and seals after rubber is processed finished product in the present automotive oil drain pan; But in watering the process of rubber,, cause plastic skeleton seal product to produce distortion and shrink, cause location dimension to be guaranteed because the secondary of plastic skeleton seal is heated; And then can't accurately locate when causing installing; Easy damage plastic skeleton seal, cause the product defect rate higher, influence sealing effectiveness, reduction service life.
The day for announcing is that the granted patent ZL200920167945.7 on May 26th, 2010 discloses a kind of engine sump tank sealing gasket, and it comprises standing part and hermetic unit; Said standing part is provided with the bolt hole of a plurality of fixedly usefulness, said hermetic unit and the standing part structure that is formed in one.The utility model adopts the aluminium sheet and the vulcanization of rubber all-in-one-piece sealing gasket of moulding, has improved mounting stability; Adopt biconvex to play hermetically-sealed construction, particularly at the place, hole of each set bolt, part outer lug thickness is thicker than internal projection, has improved sealing property.Yet same because sealing gasket overall structure flat thin, area is big, in forming process, produces distortion easily and shrinks, and causes location dimension to be guaranteed, and then defective such as can't accurately locate when causing installing.
The utility model content
The utility model is easy to generate the distortion contraction for the plastic skeleton seal that solves in the existing automotive oil drain pan; Cause location dimension to be guaranteed; And then can't accurately locate when causing installing; Damage the plastic skeleton seal easily; Cause the product defect rate higher, influence sealing effectiveness, reduce present situation and provide a kind ofly can solve effectively that plastic skeleton seal secondary receives thermal contraction, location dimension is inaccurate and the sealing bit loss is hindered the oil sump seal location moulding tool of problem such as service life.
The utility model is to solve the problems of the technologies described above the concrete technical scheme that is adopted to be: a kind of oil sump seal location moulding tool; It is characterized in that: comprise the moulding location-plate; And the some reference columns that are located at the moulding location-plate, the installation in the shape of said reference column and distributing position thereof and the oil sump seal or the position and the shape of locating hole are corresponding.Simple in structure; Putting into metallic sintered products and the product after plastic skeleton injects rubber when adopting injection moulding just put into a kind of the utility model location moulding tool and further locatees and be molded into final products before cooling not; Reduced the plastic skeleton seal and received thermal contraction, distortion, defect problems such as the inaccurate and sealing bit loss wound of the location dimension that is caused at secondary.Reach the raising product percent of pass, improve the effect of product service life and raising positioning accuracy.Thereby guaranteed the accuracy of relative position between installation/locating hole, the damage of the plastic skeleton rubber parts that has produced because of the product dislocation when also having eliminated simultaneously installation.
As preferably, the upper surface of moulding location-plate and oil sump seal parallel.Improve the moulding flatness.
As preferably, be provided with metallic sintered products in described installation or the locating hole.
As preferably, the outside dimension of described moulding location-plate is greater than the outside dimension of oil sump seal.Improve moulding positioning action convenience and reliability.
As preferably, the height of described reference column protrusion moulding location-plate is greater than the thickness of installation or locating hole.Improve moulding positioning action convenience and reliability.
The beneficial effect of the utility model is: simple in structure; Putting into metallic sintered products and the product after plastic skeleton injects rubber when adopting injection moulding just put into a kind of the utility model location moulding tool and further locatees and be molded into final products before cooling not; Reduced the plastic skeleton seal and received thermal contraction, defect problems such as the inaccurate and sealing bit loss wound of the location dimension that is caused at secondary.Reach the raising product percent of pass, improve the effect of product service life and raising positioning accuracy.Thereby guaranteed the accuracy of relative position between installation/locating hole, the damage of the plastic skeleton rubber parts that has produced because of the product dislocation when also having eliminated simultaneously installation, final products good sealing effect.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed description.
Fig. 1 is the structural representation of the preferred implementation when in the utility model oil sump seal location moulding tool the oil sump seal being housed.
Fig. 2 is that the B-B of Fig. 1 is to the sectional structure sketch map.
Among Fig. 3 Fig. 1 A-A to amplification sectional structure sketch map.
Fig. 4 is to use the oil sump seal configuration sketch map in the utility model oil sump seal location moulding tool.
The specific embodiment
Among Fig. 1, Fig. 2, the embodiment shown in Figure 3; A kind of oil sump seal location moulding tool; Comprise moulding location-plate 10; And be installed in several reference columns 11 that all cooperate with oil sump seal installation or locating hole 21 opposite positions and shape on the moulding location-plate 10, the installation in the shape of said reference column 11 and distributing position thereof and the oil sump seal 20 (seeing Fig. 1, Fig. 4) or the position and the corresponding cooperation of shape of locating hole 22 (see figure 4)s.The upper surface 12 and the oil sump seal 20 of moulding location-plate 10 parallel.Be embedded with metallic sintered products 21 in installation or the locating hole 22, the outside dimension of type location-plate 10 is greater than the outside dimension of oil sump seal 20, and the height of the reference column 11 protrusion moulding location-plates of being installed 10 is greater than the thickness (see figure 2) of installation or locating hole 22.
When locating moulding; Put into metallic sintered products 21 and the product after plastic skeleton injects rubber 23 when adopting injection moulding and before cooling not, just put into the utility model location moulding tool and further locate and be molded into final products, reduced producing the possibility that distortion is shunk to a greater extent.
Although this paper has used moulding location-plate, reference column, installation or terms such as locating hole, upper surface morely; But do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; It all is contrary with spirit of the present invention being construed to any additional restriction to them.
