Description

Anti-overflow compression mod

Technical field

The utility model is related to notebook computer accessories manufacturing technical field, more particularly to a kind of anti-overflow compression mod.

Background technology

Have in notebook computer part some be by the metalwork of die cast, because notebook computer profile is flat, So metalwork is also generally planar to sprawl structure.In general press casting procedure, motlten metal enters from mould middle part, then past Extend out and be scattered to whole die cavity.Metalwork is one-to-one with compression mod, and die casting different metal part uses same equipment, institute Can be replaced with compression mod, so want detachable with the feed head in equipment, but if the sealing of feed head and compression mod is bad, can , there is accident in energy meeting flash.

The utility model is just to provide for a kind of new die casting mold structure to solve the above problems.

Utility model content

Main purpose of the present utility model is to provide a kind of anti-overflow compression mod.

The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of anti-overflow compression mod, including with first The male model and the master mold with the second die joint and the second cavity surface of die joint and the first cavity surface, the master mold are provided with material Set, the material set has outer small interior big taper hole, and tapered shunting is contained in the material set, the sub- conical surface of shunting Taper is identical with the taper of the taper hole；Inlet channel is provided with second cavity surface, the conical surface of shunting is provided with rank Connect the splitter box of the inlet channel.

Specifically, material set includes coaxial integrally formed upper and lower part, the external diameter on the top is more than under described The external diameter in portion, is arranged with retaining ring on the outside of the bottom, the retaining ring is held between the top and the master mold.

Specifically, folder forces to form some emptyings between the edge of the edge of first die joint and second die joint Runner.

Further, the remittance that the emptying runner is extended to from first cavity surface is additionally provided with first die joint Chute.

Further, the gap width of the emptying runner is gradually reduced from inside to outside.

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

1st, the utility model can form motlten metal at splitter box and enter in the presence of there is thrust at the sub- rear portion of shunting, only The passage of die cavity, it is to avoid overflow；

2nd, the space between retaining ring energy sealing material set and master mold, it is to avoid motlten metal overflows and liquid enters air stream enter runner；

3rd, collecting tray makes the greater number of outlet on die cavity be compiled in small number of several emptying runners, reduces mould and adds Work difficulty；

4th, the structure of emptying runner inner wide and outer narrow makes increasing by resistance, promotes fluid internal pressure to make motlten metal uniform Distribution, improves mould effect.

Specific embodiment

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

As shown in Figures 1 to 4, a kind of anti-overflow compression mod of the present utility model, including with the first die joint 11 and The male model 1 of one cavity surface 12 and the master mold 2 with the second die joint 21 and the second cavity surface 22, the edge of the first die joint 11 Some first corrugated parts 111 are provided with, the edge of the second die joint 21 is provided with the second corrugated part of some supporting first corrugated parts 111 211, the first corrugated part 111 and the folder of the second corrugated part 211 force to form corrugated emptying runner 102, on the first die joint 11 also It is provided with the collecting tray 112 that emptying runner 102 is extended to from the first cavity surface 12.Motlten metal injects from the middle of male model 1 and master mold 2 Die cavity, then spreads until filling up whole die cavity, emptying runner 102 drives mould out of there is provided type chamber air by toward surrounding Passage, after motlten metal is full of die cavity, it will be imported into the then slow outflow of several emptying runners 102 through collecting tray 112, Corrugated emptying runner 102 can produce resistance higher for motlten metal, and motlten metal is by emptying runner 102 Can be hindered, so the pressure distribution in die cavity can allow motlten metal to be flowed toward the small place of resistance, thus can Motlten metal is allowed to be supplied toward the position not being filled in die cavity, it is to avoid the die-cast product after shaping produces the undesirable conditions such as cavity. Collecting tray 112 makes the greater number of outlet on die cavity be compiled in small number of several emptying runners 102, reduces mould difficult processing Degree.

As shown in figure 4, the gap width of emptying runner 102 is gradually reduced from inside to outside.Such structure makes passage effective It is gradually reduced by area, this can make the motlten metal from this emptying discharge of runner 102 be subject to increasing resistance, promote stream Pressure evenly distributes motlten metal in vivo, improves mould effect.

As shown in Fig. 1, Fig. 3, Fig. 5 and Fig. 6, master mold 2 is provided with material set 3, and material set 3 has outer small interior big taper hole 33, the Inlet channel 221 is provided with two cavity surfaces 221, tapered shunting 4 is contained in material set 3, shunt the taper and cone of sub 4 conical surface The taper in hole 33 is identical, and the conical surface of shunting 4 is provided with the splitter box 41 of linking inlet channel 221.Shunting 4 is socketed with material set 3 Together, because both profiles are supporting, in the presence of there is thrust at sub 4 rear portion of shunting, can only be formed at splitter box 41 Motlten metal enters the passage of die cavity, it is to avoid overflow.The outside of taper hole 33 of material set 3 is docked with the charging aperture of equipment, so molten Melt metal and enter the direction of pan feeding set 3 along material 3 axis of set, and when passing through splitter box 41 into die cavity, flow direction is changed into along die cavity Flow direction, be so conducive to motlten metal along die cavity to external diffusion.

As shown in figures 1 to 6, material set 3 includes coaxial integrally formed top 31 and bottom 32, and the external diameter on top 31 is more than The external diameter of bottom 32, the outside of bottom 32 is arranged with retaining ring 5, and retaining ring 5 is held between top 31 and master mold 2.Retaining ring 5 Space between energy sealing material set 3 and master mold 2, it is to avoid motlten metal overflows and liquid enters air stream enter runner.

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