Description
Technical field
The present invention relates to mold injection technical fields specifically to further relate to more particularly to a kind of set beer die processing method
A kind of set beer die processing method of cell-phone cover.
Background technology
It is also referred to as encapsulated to cover beer, is a kind of die processing method, the mold for covering beer is known as covering beer mold (rubber-coating module
Tool), also referred to as post forming mould.Such mold needs two sets of plastic moulds, typically first carries out ebonite part, then will be at
The good ebonite of type is put into injection molding package in flexible glue mold, and compared to dual-color plastic rubber mold, what set beer mold need not be special is double
Color injection molding machine, die cost is lower, also more flexible.
Existing cell-phone cover is to obtain higher shatter-resistant performance and abundant appearance, and generally use set beer mold is added
Work meets product requirement by the combination of two kinds of different materials such as PC plastic and TPU materials.
For the cell-phone cover of certain model, since the limitation of structure causes PC sheet material location difficulties, TPU to need to do three into glue
A template die simultaneously turns the thin mouth of a river style big water gap and carries out side into being molded by way of glue, can leave glue-feeder in this way, need to manually add
Work removes glue-feeder, increases processing cost.The structure chart of existing cell-phone cover as shown in Figure 1, Fig. 2 is the A-A sectional views of Fig. 1,
Cell-phone cover 1 is made of PC sheet materials 11 and TPU sheet materials 12, to solve PC sheet material orientation problems, is had by increasing in 1 tail portion of cell-phone cover
Two crescent moon location holes 2, are positioned by crescent moon location hole 2, set beer injection molding are then carried out again, the shortcomings that this method
It is that final product can leave crescent moon location hole in cell-phone cover tail portion, affects product appearance, and the tooth moon positions when product stripping
Slight fracture phenomenon is also had at hole 2.
For the cell-phone cover of certain model, the mobile phone back side has camera or fingerprint hole, the injection molding in covering beer mold
When product, it may appear that the slight burst conditions of deviation voltage protection film and PC sheet material location holes periphery need to make to solve the problems, such as this
Special positioning fixture, which is put into mold, carries out set beer, and PC sheet materials fill localization tool, then localization tool is attached on injection molding machine,
Process time is very long, and efficiency is very low and PC sheet perimeters equally have burst conditions appearance.Equally, as using in cell-phone cover tail
Portion, which increases by two crescent moon location holes, can solve the problems, such as positioning built-up time length, but the slight burst conditions of PC sheet perimeters equally can
Occur, and product appearance is affected.
Invention content
The purpose of the present invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of set beer die processing method.
The present invention realize goal of the invention the technical solution adopted is that：A kind of set beer die processing method, has to process
The product of hole bit architecture, includes the following steps：
A. the first sheet material is obtained by the first injection mould processing；
B. at least two location holes in different size are processed by the CNC methods processed on first sheet material,
All location holes are no more than the range of the hole bit architecture；
C. first sheet material is placed in the second injection mold, is positioned first sheet material by the location hole,
Then set beer injection molding is carried out, the second sheet material is molded on first sheet material；
D. the hole bit architecture is processed on first sheet material by the CNC methods processed, obtains product.
Preferably, the step c further includes：When carrying out set beer injection molding, the glue-feeder of injection molding machine is arranged in institute
In the range of stating hole bit architecture.
Specifically, the product is cell-phone cover.
Preferably, first sheet material is PC plastic, and second sheet material is TPU materials.
Specifically, the hole bit architecture is camera shooting head bore or fingerprint hole.
The beneficial effects of the invention are as follows：
1, processing method of the invention first processes two location holes smaller than actual apertures position in the first sheet material by CNC,
The TPU of injection molding machine is made in simultaneously on the hole bit architecture for needing CNC to process into glue point, waits injecting products out CNC processing removal again
Fall, processing method of the invention is suitble on all products that can not be positioned and need to be processed into glue with TPU, and solving product can not position
Problem, for the product for having positioning, there is slight slight crack problem on product orientation hole periphery after overcoming injection molding.
2, TPU is solved the problems, such as into there are the mouths of a river to process after glue.
3, the high problem of existing mold processing scrappage is overcome, so that mould structure is become two template dies by three template dies, saves
About manufacturing cost and cost of labor.
