Description
Technical field
The utility model is related to IML injection molds field, and in particular to a kind of base material location structure of IML injection molds.
Background technology
Recently as China's economic development, the face-piece of the existing various types of communication electronics of in the market and household electrical appliance is adopted mostly
Use IML（In-mode inserts are molded）Face-piece, Film film printings is good by forming machine Forming shapings, then by cutting die cold cut
Shaping, finally carried out in injection mold injection and produce using manually or mechanically planting personally, the characteristics of its technique highly significant
It is that surface is one layer of transparent membrane of hardening, centre is printing pattern layer, and the back side is plastic layer, and transparent membrane can prevent product
Only surface is scratched and rub resistance, and patterned layer is clipped in the middle, and can for a long time keep the distinctness of color to be difficult to fade.
In mold injection, the Dicoration base material for generally requiring to have printed is put into injection mold, is then noted resin
Penetrate at the back side of Dicoration base material, Dicoration base material is integrally formed with resin-bonded, the products formed entirety to three-dimensional shape can be carried out
Decorating printing, makes product reach ornamental and feature effect.The location structure of traditional IML injection molds is usual
It is that one boss is set in front cavity, the hole on base material passes through boss, so as to base material be positioned with front cavity, in rear cavity
Position corresponding to boss is provided with a groove, and boss is inserted through with groove when matched moulds.Before injection, first base material is put
Put in front cavity, the hole on base material passes through from boss, so as to base material and front cavity be positioned, when matched moulds, boss
It is inserted into the groove of rear cavity, the front cavity boss height of this structure is restricted, it is impossible to too high, and otherwise product can glue front mould
Benevolence, and boss and groove can produce abrasion when being inserted through to die, make the die lost of life, improve cost；In addition, boss is also
Modular angle is made, this can influence base material positioning precision again so that fraction defective is improved.
Current country IML base material implanted prosthetics has aspiration to position and base material auxiliary handle location technology.Aspiration location technology
It is general to be positioned in front mould using getter device, complex process, it is necessary to using mould, three sets of shearing die and injection mold
Mould is processed, and when product appearance requirement is high and plastic material mobility is very good, this technology will be lost on the surface of product
Stay trace.And base material auxiliary handle location technology is typically positioned using base material and extend base material on side（Abbreviation auxiliary handle）, to do
Positioned into variously-shaped, matching is poor between kinds of processes, quality is unstable, the production process time is long and environmental condition will
Ask complicated, cause product percent of pass low, when product appearance requirement is high and IML 3D injection mouldings, this technology will be in auxiliary handle
There are many winged silks with hand with the edge of product, finished product yield is low.Factors above causes production cost high, so that the technology is pushed away
It is wide for many years still cannot large area use.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model be provide a kind of simple structure, it is reasonable in design,
Production efficiency is high, finished product rate and product quality are high, and equipment investment expense is greatly reduced, so as to reduce production cost
A kind of base material location structure of IML injection molds, with effectively solving the problems, such as background technology.
In order to solve the above technical problems, the utility model provides following technical scheme：
A kind of base material location structure of IML injection molds, including upper cores, lower die and be fixed on four angles of lower die
Alignment pin, the locating piece for positioning base material is provided with lower die, it is parallel on locating piece to offer two bar holes, institute
That states bar hole opens up that direction is vertical with corresponding material edge, and the locating piece is fixed on by bolt through the bar hole
On lower die, the upper cores bottom is arranged with fixed plate, and limited impression is offered in fixed plate, in the locating piece outer end pair
Defining flange should be provided with the position of limited impression, itself and limited impression mating reaction, by limited impression and defining flange
Be clasped to limit the position of locating piece.
Further, described locating piece is the locating piece of a wedge shape, and the side wall of each locating piece is born against above-mentioned
On the side wall of base material.
Further, the locating piece is pushed down and less than base material joint 0.01-0.03 mm, to extension elongation in base material
It is 0.03-0.08 mm.
Further, with the locating piece coaxial corresponding upper cores fixed plate extruding contact surface on be equipped with
The second groove that corresponding locating piece setting-in coordinates.
Further, the fixed plate is connected by flexible member with upper cores, and alignment pin is corresponded in the fixed plate
Position at be provided with dowel hole.
Further, the flexible member has 4, is separately positioned on four angles of fixed plate.
Further, the flexible member is in compressive state when mould matched moulds, and the flexible member is spring.
The beneficial effects of the utility model are：Compared with prior art, base material location structure of the present utility model utilizes spiral shell
Be fixed on locating piece on lower die through the bar hole on locating piece by bolt, and locating piece can be moved along the bar hole one of itself
Complete the adjustment of position location；When base material is placed on lower die, lower die is positioned with alignment pin, while with calmly
Position block is positioned to base material, and during matched moulds, the active force that flexible member gives can also increase compaction degree；Limited impression on pressing plate
Design with the second groove can also increase compaction degree of the mould to base material, also, it also ensures base material uniform force；Matched moulds
Afterwards, elasticity edge element is in projecting inward highly small of upper cores, contributes to product to depart from upper cores during die sinking, and can reduce product to glue
The possibility of upper cores.The simple structure, is easy to the installation of mould, shortens the time of die debugging and improves location structure
Positioning precision and workpiece production efficiency.
