Fig. 1 to Fig. 7 is please referred to, the fixed structure 10 of the nut in-mould injection of the utility model embodiment includes for pacifying
The positioning column 12 of loading nut, positioning column 12 are equipped with elastic component 14.It is provided on elastic component 14 and at least partly protrudes from positioning column
12 convex block 142.
The fixed structure 10 of the nut in-mould injection of the utility model embodiment is installed by nut to positioning column 12
When, convex block 142 can be by the offer pressure of elastic component 14 to block nut, can be to avoid nut is fallen from positioning column 12 and causes to press
Bad mold.Moreover, the fixed structure 10 of nut in-mould injection is applicable to thread aperture nut not of uniform size.
It is appreciated that nut in-mould injection is to be placed on nut in injection mold to be molded, after injection molding machine molding
Nut is integrally formed with moulding.When nut in-mould injection, need for the screw thread hole of nut to be inserted in the positioning column 12 of injection mold
On with fixture nut.In the present invention, at least partly protruding positioning pole 12 of convex block 142.Positioning is inserted in nut installation
When column 12, convex block 142 by nut squeeze and to being retracted inside fixed structure 10, elastic component 14 by convex block 142 extruding and
Reaction force (pressure) is provided to convex block 142, convex block 142 is allowed to block nut according to the thread pore size of nut, from
And nut is avoided to cause to damage mold by pressure due to injection mold vibration is fallen from positioning column 12.In this way, nut in-mould injection is consolidated
Determine structure 10 and is applicable to thread aperture nut not of uniform size.When not installing nut on fixed structure 10, convex block 142 by
To elastic component 14 active force and to stretching out outside fixed structure 10.Therefore, convex block 142 is to be telescopically disposed in fixed structure
10。
Specifically, referring to Fig. 4, one end of the remotely located column 12 of convex block 142 and the central axis distance d of positioning column 12 are big
In the thread pore radius of nut.In this way, convex block 142 can partly protrude from positioning column 12, when installing nut on fixed structure 10
When, pressure is provided to convex block 142 from elastic component 14, and convex block 142 is allowed to block nut.
In the present invention, elastic component 14 includes end 144, and convex block 142 is arranged in end 144.Elastic component 14 is arranged
In positioning column 12.Convex block 142 is arranged in the end 144 of elastic component 14, and elastic component 14 is arranged in positioning column 12, by spiral shell
When mother's installation to positioning column 12, nut is blocked using the elasticity of elastic component 14 conducive to convex block 142.Preferably, elastic component 14 is bullet
Property pin.
Further, elastic component 14 is in the form of a column, and the length of elastic component 14 is consistent with the length of positioning column 12.It is appreciated that
Elastic component 14 is arranged in positioning column 12, and the length of elastic component 14 is consistent with the length of positioning column 12, and nut can preferably be consolidated
It is scheduled on positioning column 12.Certainly, the length of elastic component 14 is also smaller than the length of positioning column 12, only need to guarantee to install on nut to
When positioning column 12, the convex block 142 that the end 144 of elastic component 14 is arranged in can block nut.
In the present invention, positioning column 12 includes cylinder 122 and the positioning region 124 for being set to 122 top of cylinder.Positioning
Portion 124 is for installing nut.Convex block 142 at least partly protrudes from positioning region 124.Specifically, positioning region 124 includes first fixed
Position and is spaced the second opposite locating piece 1244 with the first locating piece 1242 at block 1242.Convex block 142 from the first locating piece 1242 with
Projection between second locating piece 1244.
In the example shown, cylinder 122 is cylindrical body, and positioning region 124 is the cylindrical body of one cuboid of intermediate removal, so that convex block
142 by nut squeeze the positioning region Shi Kexiang 124 inside be retracted, elastic component 14 by after the extruding of convex block 142 to convex block 142
It provides reaction force (pressure), so that convex block 142 blocks nut.It is appreciated that positioning column 124 can also be any other suitable
Shape need to only guarantee that convex block 142 is being squeezed retraction inside the positioning region Shi Kexiang 124 by nut, be not limited thereto.Into
One step, the diameter of cylinder 122 is greater than the diameter of positioning region 124, in favor of nut installation to be located on positioning region 124.It is fixed
When position portion 124 is the cylindrical body of one cuboid of intermediate removal, positioning region 124 include the first locating piece 1242 and with the first locating piece
The second opposite locating piece 1244 of 1242 intervals.Preferably, 1244 shape size one of the first locating piece 1242 and the second locating piece
It causes.Elastic component 14 is arranged between the first locating piece 1242 and the second locating piece 1244, and the end 144 of elastic component 14 is arranged in
The projection between the first locating piece 1242 and the second locating piece 1244 of convex block 142 stablizes installation in favor of nut.
Further, the top of positioning region 124 is formed with guiding surface 1246, the top-down direction of guiding surface 1246
It is inclined outwardly.When positioning region 124 is the cylindrical body of one cuboid of intermediate removal, the top of the first locating piece 1242 and second is determined
The top of position block 1244 is each formed with guiding surface 1246.The setting of guiding surface 1246 is so that nut is easily mounted on positioning column
On 12.
In the present invention, the fixed structure 10 of nut in-mould injection includes pedestal 16, and pedestal 16 is arranged in cylinder 122
Bottom.Fixed structure 10 can connect the pedestal of injection mold by pedestal 16.
In the present invention, convex block 142 is elastic projection.When installing nut to positioning column 12, elastic projection
Nut can be blocked because of the elasticity of itself.Preferably, the external surface shape of convex block 142 is arc, so that nut is easily mounted to
Positioning column 12.In other embodiments, when convex block 142 is elastic projection, directly convex block 142 can be arranged in positioning column
On 12, nut is blocked merely with the elasticity of convex block 142 itself.In this way, without setting elastic component 14 in positioning column 12.
Referring to Fig. 8, the injection mold 100 of the utility model embodiment is used for nut in-mould injection.Injection mold 100
