Description
Technical field
The present invention relates to a kind of lens mould core fixing structure.
Background technology
The imaging eyeglass is widely used in the various electronic installations.The imaging eyeglass that is applied at present in the portable electron device generally adopts plastic material to obtain by injection mo(u)lding.Include a plurality of dies in the mould in order to the shaping eyeglass, be injected into after described plastic cement is heated in the formed die cavity of die, after supercooling, just formed eyeglass.Existing die generally is to be screwed onto in the mould by bolt, in each repairing, maintenance process to die, described die all can be removed and change or keep in repair, yet the position that reinstalls to the die in the mould often is subjected to the pretightning force influence of construction bolt, be applied to power on the construction bolt because can't record operator in the installation process accurately, thereby can't accurately described die be installed in the pre-position.Need to adjust by rectification repeatedly the position of die after die installs, this process is not only time-consuming, and influences the stability of lens quality.
Summary of the invention
In view of this, be necessary to provide the lens mould core fixing structure of a kind of fast changeable and installation.
A kind of lens mould core fixing structure, it comprises a backboard, a module, a plurality of set bolts and at least one die.Be formed with at least one die cavity and perforation that at least one runs through described module and is connected with described die cavity on the described module, described module is installed on the described backboard by described set bolt.Described die comprises a body and a core rod that is connected on the body.Described body is arranged in the described die cavity and the one end supports on described backboard.Described core rod is by passing in the described perforation.This lens mould core fixing structure also comprises at least one spring, and described spring is arranged between the bottom surface of the body of described die and described die cavity, and supports after the compression on the body of the bottom surface of described die cavity and described die.
Compare prior art, lens mould core fixing structure of the present invention adopts spring that die is applied fastening force, as long as the distance between the bottom surface of described die and described die cavity does not change, the length of described spring just can not change, thereby make and be applied to installation and the replacing that the fastening force on the described die does not change yet and makes things convenient for die, simplify the operation of die installation and repair and replacement, saved the time simultaneously.

The specific embodiment
See also Fig. 1 to 4, the lens mould core fixing structure 100 of better embodiment of the present invention, it comprises 110, one modules 120 of a backboard, a plurality of set bolts 130, at least one die 140 and at least one spring 150.Be formed with at least one die cavity 122 and perforation 124 that at least one runs through described module 120 and is connected with described die cavity 122 on the described module 120.Described module 120 is installed on the described backboard 110 by described set bolt 130.Described die 140 is arranged in the die cavity 122 of described module 120, and the one end is by passing in the described perforation 124, and the other end supports on described backboard 110.Be arranged between the bottom surface of described die 140 and described die cavity 122 after described spring 150 compressions.
Described backboard 110 is arranged in the injection machine (figure does not show).110 comprise 112, one lower surfaces 114 of a upper surface on the described backboard, and a plurality of its upper and lower surperficial through hole of 112,114 116 that runs through.
Described module 120 comprises an end face 123 and a bottom surface 125.Described die cavity 122 is formed on the end face 123 of described module 120, and extends certain distance by described end face 123 to the direction of its bottom surface 125.Described perforation 124 is formed on the bottom surface 125 of described module 120, and extends to the position that is connected with described die cavity 125 by described bottom surface 125.The diameter of described die cavity 122 is greater than the diameter of described perforation 124, thereby forms the step 127 around described perforation 124 in the bottom of die cavity 122.On the end face 123 of described module 120, also offer through hole 116 corresponding a plurality of bolts hole 126 with described backboard 110.
Thereby described a plurality of set bolt 130 passes the through hole 116 of described backboard 110 and is screwed onto in the bolt hole 126 on described module 120 end faces 123 described module 120 is fixed on the described backboard 110.
Described die 140 comprises that a body 142 and one are connected body 142 upper mold core 144.Described body 142 manners are in the die cavity 122 of described module 120, and described core rod 144 is set in the perforation 124 of described module 120 and by stretching out a segment distance in the described perforation 124.One end of described body 142 supports on described top board 110.
Be arranged on after 150 compressions of described spring between the step 127 of the body 142 of described die 140 and module 120.Thereby act on fixing described die 140 on the described die 140 by its restoring force behind the described spring 150 compression certain-lengths, because the spacing between the body 142 of described die 140 and the step 127 of described module 120 is certain, and be difficult for changing, therefore the length that is arranged on the spring 150 between the step 127 of the body 142 of die 140 and module 120 just is fixed, therefore the restoring force that is produced by the deformation of spring 150 just is fixed, therefore, the fastening force of the spring 150 that described die 140 is suffered immobilizes, thereby make die 140 in maintenance and replacing process, needn't carry out position correction to die 140 again, simplified the operation that die is installed and changed, the speed of the die of having accelerated replacing simultaneously and having installed is saved time.
In addition, regulate the suffered fastening force of die 140 for convenience, a pad 160 can be set between the body 142 of described backboard 110 and die 140, change the distance between the step 127 of the body 142 of described die 140 and module 120 by the thickness of adjusting this pad 160, thereby change the deformation length of spring 150, to realize adjusting to the suffered fastening force of die 140.In order to prevent that described pad 160 is offset, can on the lower surface 114 of described backboard, offer a groove 118 in the position of corresponding described die 140, described pad 160 is contained in the described groove 118.
Be noted that above-mentioned embodiment only is better embodiment of the present invention, those skilled in the art also can do other variation in spirit of the present invention.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
