Description

Encapsulated part metal part compression mod

Technical field

It the utility model is related to die-casting technique field, it is more particularly to a kind of to prevent bad encapsulated in encapsulated products border Part metal part compression mod.

Background technology

It is the encapsulated part of metal to have some in intelligent appliance, that is to say, that encapsulated part product some be to pass through compression mod Has the die cast metal part of shaping, another part fills plastic cement formation using encapsulation die on the basis of die casting.In order that Metal part and plastic portions are firmly connected, and structure of caving in often is provided with die cast metal part, and plastic cement will enter structure of caving in and work as In, being fitted together in a kind of structure is formed, so can just make product structure stable.

In general plastic cement filling process, melt plastic cement enters in the middle part of mould, is then diffused into metalwork die cavity outward. The difficult point of this process is to control the border of two kinds of materials bad.If die casting can not in rubber-coating module precision-fit, bag Glue part product is easy to excessive glue occur in plastic cement filling process, runs phenomena such as flash.But actual die casting is because die casting A series of reasons such as molten metal skewness, deformation are likely to occur in journey, often cause die casting to be sealed with rubber-coating module Unreal, rubber-coating module is changed anyway, and scrappage is all difficult to reduce.

The utility model is just to provide for a kind of new scheme to solve the above problems.

Utility model content

Main purpose of the present utility model is to provide a kind of encapsulated part metal that encapsulated products border can be prevented bad Part compression mod.

The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of encapsulated part metal part compression mod, including The male die core and mother module core of mutual split, the male die core have the first cavity surface, and the mother module core has the Second-Type of indent Cavity surface, first cavity surface force to form the die cavity for connecting charging aperture with the second cavity surface folder；Second cavity surface is encapsulated Border is provided with step edge, and the depth of the step edge is 0.06mm, width 0.3mm.

Specifically, the mother module core is provided with some projections for being close to the second cavity surface non-packet glue border, the male model Benevolence is provided with the groove that caves in for avoiding the projection, described to cave in groove and projection folder is forced to be formed from die cavity and extends to confluxing outside mould.

Specifically, the mother module core covers provided with material, shunting of taper is contained in the material set, it is described to shunt on son Provided with the splitter box for being connected the charging aperture.

Further, the material set includes coaxial integrally formed upper and lower part, and the external diameter on the top is more than described The external diameter of bottom, the outer sheath of the bottom are provided with retaining ring, and the retaining ring is held in the top and the mother module core Between.

Using above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model is：

1st, the utility model improves the excessive glue solved in encapsulation process by the details of compression mod, runs the problems such as flash, Make the outward appearance of encapsulated part with regard to the requirement of client can be reached.

2nd, cave in groove and projection will make metal material head have turnover with respect to useful part, be easily processed metal material head.

3rd, shunting makes molten metal flow direction be changed into the flow direction along die cavity, is so advantageous to molten metal along die cavity To external diffusion.

4th, the space between retaining ring energy sealing material set and master mold, avoid molten metal from overflowing and enter air stream enter runner with liquid.

Embodiment

The utility model is described in further detail with reference to specific embodiment.

Embodiment：

As shown in Figures 1 to 4, a kind of encapsulated part metal part compression mod of the present utility model, the public affairs of mutual split are included Die 1 and mother module core 2, male die core 1 have the first cavity surface 11, and mother module core 2 has the second cavity surface 21 of indent, the first die cavity Force to form the die cavity for connecting charging aperture 101 with the second cavity surface 21 folder in face 11；Second cavity surface 21 is provided with step on encapsulated border Edge 211, the depth of step edge 211 is 0.06mm, width 0.3mm.

As shown in Figure 4 and Figure 6, encapsulated processing step is as follows：

1. die casting：The die casting 6 that encapsulated marginal swell is flange 61 is molded in compression mod；

A 2. trimming：Metal material head unnecessary around die casting 6 is cut off；

It is 3. encapsulated：The die casting 6 of trimming is placed in rubber-coating module, the forming plastic cement part 7 around die casting, forms bag Glue part；

4. secondary trimming：Plastics material head unnecessary around encapsulated part is cut off.

This technique is not to improve product yield by rubber-coating module improvement, but improves product yield by compression mod. Because mother module core 2 has a step edge 211, on die casting 6 can the junction section with plastic portions 7 have more one be higher by it is flat Face about 0.06mm flange 61, the flange 61 do not interfere with the performance of encapsulated part.But such die casting 6 be placed in rubber-coating module work as When middle, flange 61 can preferably near closed hollow ring, prevention plastic portions 7 penetrate into pressure across flange 61 under the pressing deformation of mould In the plane of casting 6, so encapsulated part is not in excessive glue, runs phenomena such as flash in the intersection of two kinds of materials, encapsulated part Outward appearance is with regard to that can reach the requirement of client.

As shown in Figures 2 and 3, mother module core 2 is provided with some projections 22 for being close to 21 non-encapsulated border of the second cavity surface, male model Benevolence 1 is provided with the groove 12 that caves in for avoiding projection 22, caves in groove 12 and the folder of projection 22 is forced to be formed from die cavity and extends to confluxing outside mould 102.The die cavity of compression mod is that substantitally planar is sprawled, so die casting 6 can in the form of sheets, from confluxing, 102 parts overflowed will It is changed into metal material head.Cave in groove 12 and projection 22 will make metal material head have turnover with respect to useful part, metal material head is easily located Reason is fallen.

As shown in Figure 1 and Figure 5, mother module core 2 is provided with material set 3, and material set 3 has outer small interior big taper hole 33, received in material set 3 Have shunting 4 of taper, tapered shunting 4 is contained in material set 3, shunt the cone of the taper and taper hole 33 of sub 4 conical surfaces Spend identical, splitter box 41 of shunting 4 provided with linking charging aperture 101.Shunting 4 connects together with material set 3, because both Profile is supporting, so in the presence of having thrust at sub 4 rear portions of shunting, only molten metal can be formed at splitter box 41 enters die cavity Passage, avoid overflow.The outside of taper hole 33 of material set 3 is docked with the charging aperture 101 of mould, so molten metal enters pan feeding set Along when expecting 3 axis of set, and entering die cavity by splitter box 41, flow direction is changed into the flow direction along die cavity, so favourable in 3 direction In molten metal along die cavity to external diffusion.

As shown in figure 5, material set 3 includes coaxial integrally formed top 31 and bottom 32, the external diameter on top 31 is more than bottom 32 external diameter, the outer sheath of bottom 32 are provided with retaining ring 5, and retaining ring 5 is held between top 31 and master mold 2.Retaining ring 5 can be close Space between envelope material set 3 and master mold 2, avoids molten metal from overflowing and enters air stream enter runner with liquid.

Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art, On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality New protection domain.
