The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of runner improves compression mod, including with the The male model and the master mold with the second die joint and the second cavity surface of one die joint and the first cavity surface, first die joint Edge be provided with some first corrugated parts, the edge of second die joint is provided with the second of some supporting first corrugated parts Corrugated part, first corrugated part forces to form corrugated emptying runner with second corrugated part folder.

Specifically, be additionally provided with first die joint from first cavity surface extending to confluxing for the emptying runner Groove.

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

Specifically, the master mold is provided with material set, inlet channel is provided with second cavity surface, is contained in the material set Shunting, shunting is provided with the splitter box for being connected the inlet channel.

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, is arranged with retaining ring on the outside of the bottom, the retaining ring be held in the top and the master mold it Between.

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

1st, emptying flow passage structure of the present utility model makes motlten metal increase by pressure, promotes motlten metal to flow to die cavity The position of interior underfill, it is to avoid the die-cast product after shaping produces the undesirable conditions such as cavity；

2nd, 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；

3rd, 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；

4th, splitter box is conducive to motlten metal along die cavity to external diffusion, it is to avoid multiple feed produces the problem of flow liner；

5th, 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.

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 runner of the present utility model improves compression mod, including with the He of the first die joint 11 The male model 1 of the first cavity surface 12 and the master mold 2 with the second die joint 21 and the second cavity surface 22, the side of the first die joint 11 Edge is provided with some first corrugated parts 111, and the edge of the second die joint 21 is provided with the second ripple of some supporting first corrugated parts 111 Portion 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 It is additionally provided with the collecting tray 112 that emptying runner 102 is extended to from the first cavity surface 12.Motlten metal is noted from the middle of male model 1 and master mold 2 Enter die cavity, then spread 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 several emptying runners 102 then slow stream through collecting tray 112 Go out, 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 Motlten metal can be 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 bad shapes such as cavity Condition.Collecting tray 112 makes the greater number of outlet on die cavity be compiled in small number of several emptying runners 102, reduces mould and adds Work difficulty.

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.
