Description
Technical field
The present invention relates to a kind of mould structure, more particularly to a kind of car light light guide injection mold structure.
Background technology
In automobile lamp manufacturing field, headlight light guide and back light light guide are generally formed by PC (polycarbonate) material injection.
Usual car lamp mold structure not only needs to consider its feasibility and feature in design, also to ensure in injection each zero
Mating protection between part, extends the service life of each part.
And headlight light guide and back light light guide need to be connected as structural member with other car light parts.This is just needed in mould knot
Outer core pulling and sleeve, plug are needed in structure design, and core pulling generally carries certain angle.After injection terminates die sinking, outer core pulling
Retreat, ejector retainner plate can eject upwards with moving sleeve, and when molding again, sleeve is also without completely multiple when outer core pulling easily occurs in place
The situation of position, this will cause sleeve to be severed by outer core pulling, and the situation that then plug is also severed occurs.In this case not only
Injection efficiency can be influenced, and also add labour cost.And the headlight light guide of car light and the injection of back light light guide in the prior art
Mould structure design, do not solve the problems, such as this.
The content of the invention
The technical problems to be solved by the invention be to provide when one kind can effectively protect molding sleeve and plug not by
The car light light guide injection mold structure that core pulling severs.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of car light light guide injection mold structure, including dynamic model frame 5, moving die insert 2, outer core-pulling slide block 3, plug 8, sleeve
9 and ejector retainner plate 10, the moving die insert 2 is positioned at 5 top of dynamic model frame, the outer core-pulling slide block 3 through the connection of fixing screws 6
Formed with the apparent surface of 5 joint place of dynamic model frame and be sheathed on institute easy to the sliding bevel of both slide displacements, the sleeve 9
8 outer rim of plug is stated, the plug 8 passes through the ejector retainner plate 10, and the sleeve 9 is embedded on the ejector retainner plate 10, the plug 8
Perpendicular with the ejector retainner plate 10, its feature is to further include the first guide rod and the second guide rod, first guide rod and
Two guide rods are positioned on the ejector retainner plate 10 and parallel with the plug 8；Under molding state, first guide rod and
Two guide rods pass through the dynamic model frame 5, and the upper surface of first guide rod and the second guide rod is resisted against the outer core pulling and slides
The bottom surface of block 3；
The bottom surface of the single outer core-pulling slide block 3 includes one section of inclined-plane and one section of plane, and the planar section is close to described dynamic
Mould insert 2, the upper surface of the planar section and first guide rod or the second guide rod lean.
Further as the technical program is improved, and the outer core-pulling slide block 3 includes opposite one group totally two.
The further improvement of the technical program is also served as, first guide rod and the second guide rod are two-part ladder
Bar, its thicker one section is embedded in the body of the ejector retainner plate 10 completely.
Further as the technical program is improved, and the upper surface of first guide rod and the second guide rod is resisted against
The flat bottom section of the different single outer core-pulling slide blocks 3 is along interposition close to the part of the moving die insert 2.
Further as the technical program is improved, and the car light is headlight or back light.
Using the car light light guide injection mold structure of above-mentioned technical proposal, by setting two parallel guide rods to be used for mould
The reset guide of tool, realizes effective protection to sleeve and plug in the clamping process again after mould die sinking, avoids and taken out
Core such as severs at the generation of failure.

Embodiment
The specific embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings.
Car light back light light guide injection mold structure signal as depicted in figs. 1 and 2,5 upper end of dynamic model frame are provided with dynamic model edge
Block 2, acts on through fixing screws 6, both are fixed as one in connection；Formed in mould product 1 is arranged on the top of moving die insert 2, production
The left and right sides of product 1 and moving die insert 2 be provided with one group totally two can respectively to the left and right both ends with respect to the outer pumping that dynamic model frame 5 slides
Core sliding block 3, wherein sliding surface are inclined-plane.The bottom surface of outer core-pulling slide block 3 connects with the upper surface 51 of dynamic model frame 5, outer core-pulling slide block
31 bottom surface is divided into two sections, is respectively horizontal bottom surface 31 and the bottom surface 32 for inclined-plane, and the gradient of bottom surface 32 is oblique with end face 51
Degree matches.Horizontal bottom surface 31 forms what gap at one was received as the top of release link 7 with inclined 51 joint of end face
Release link groove 4, is received within the space after being stretched out through in the head driven framed 5 of the release link 7 of dynamic model frame 5, release link 7
Top surface is resisted against the lower part of horizontal bottom surface 31, wherein, both phase contacts are for bottom surface 32, closer to moving die insert 2.
In the opposite side of the mould, the mutually position of same release link 17 outer core-pulling slide block corresponding with opposite side and pass
System is symmetrically arranged compared with right side.
Downward along the position of product 1, plug 8 passes through moving die insert 2, dynamic model frame 5, ejector retainner plate 10 and ejector retainner plate backing plate respectively
Positioned after 11 through fastening plug screw 12.The outer rim of plug 8 is arranged with sleeve 9, and sleeve 9 is embedded on ejector retainner plate 10.Equally, in two sections
The stair-stepping release link 7 and 17 of formula, lower part is embedded on ejector retainner plate 10.8 and two release link 7 of plug and 17 keeping parallelisms,
It is and perpendicular with ejector retainner plate 10.
Increase release link under outer core pulling it is an object of the invention to provide a kind of ejector retainner plate forced resetting mode, to set
Cylinder, plug are protected.
At the end of die sinking core pulling retreats, the release link 7 and 17 below core pulling is with ejection and the outer core pulling upwards of ejector retainner plate 10
Sliding block 3 is not interfered.When the structure can mold again after ejection, outer core pulling module 3 can be realized on definite meaning first when resetting
The complete reset of release link 7 and 17 for making lower section is forced, then core pulling is just completed in place.And sleeve 9 also can be before core pulling in place
Already with the reset of release link 7 and 17 below core pulling, the possibility severed by core pulling is so avoided.
This car light back light light guide injection mold structure using the above structure, by outside in back light light guide injection moulding process
Increase the ejector retainner plate forced resetting mode of release link under core pulling, realize the protection to sleeve, plug.It has the following advantages that：
1st, this structure can effectively protect sleeve, plug, not severed by core pulling；
2nd, this structure improves injection efficiency, reduces labour cost, extends die life；
3rd, the cost of this structure is relatively low.
