Description
Technical field
The present invention relates to the accurate bottle cap mold in bottle cap injection mo(u)lding field, particularly novel HALF block structured high pitched tune.
Background technology
Traditional Multicavity bottle box cover die is that Angle Pin drives slide block or the HALF piece is realized undercut for what adopt.
Angle Pin drives slide block and realizes that undercut is on large slide block, slanting guide pillar hole to be set, and the width of large slide block increases, and the width of whole mould is increased.Take 48 chamber 3025 water covers as example, mould adopts 4 * 12 to arrange, and large slide block is thinner, considers on each large slide block of processability 6 chambeies of design number.Between two large slide blocks, distance increases, and the length of whole mould is increased, and such die boundary dimensions is 996mm * 596mm * 671mm.Mould with Angle Pin, except appearance and size large, cost of material is high and easily cause outside mould tenesmus, mould must guarantee that all large slide block is in position accurately when each matched moulds, matched moulds when if large slide position is inaccurate, can cause the Angle Pin fracture, cause mould to damage, even may jeopardize personal safety.Be provided with large inclined-plane on large slide block, because the length of large slide block is long, make large inclined-plane also longer, the machining accuracies such as the flatness on large inclined-plane, the depth of parallelism, perpendicularity are difficult to assurance, and processing cost increases.
Angle Pin drives the HALF piece and realize that undercut is that certain improvement has been arranged on above architecture basics, but final or unresolved Angle Pin easily causes Angle Pin fracture, the HLAF piece location inaccuracy under the matched moulds state and the problem that can't effectively protect HALF piece the weakest wedge angle position to preserve from thereof when driving HLAF piece somatotype in the mould running.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide that a kind of appearance and size is little, the low cost of manufacture of mould, the mould quality of fit is high and stable, machining accuracy easily guarantees and the accurate bottle cap mold of the novel HALF block structured high pitched tune of long service life.
purpose of the present invention is achieved through the following technical solutions: the accurate bottle cap mold of novel HALF block structured high pitched tune, it comprises the HALF piece, die cavity, large slide block A, large slide block B, wedge block, throw-out collar, thread core, the cooling water core, ejector sleeve and interior core, HALF piece up and down both ends of the surface have location taper hole and location straight hole, the both sides of HALF piece arrange the inclined-plane, die cavity coordinates the inside that is arranged on the location taper hole, the both sides of HALF piece are provided with wedge block, wedge block and inclined-plane closely cooperate, the throw-out collar of hollow coordinates the inside that is arranged on the location straight hole, the below of HALF piece is symmetrically arranged with large slide block A and large slide block B, large slide block A is fixedly mounted on the die sinking plate with large slide block B, the thread core of hollow passes successively the inside of throw-out collar and HALF piece and stretches into die cavity, the outer wall of cooling water core and the inwall of thread core are connected, ejector sleeve is set in the inside of cooling water core, outer wall and the thread core at ejector sleeve top are connected, ejector sleeve inside is equipped with interior core.
The surrounding of described HALF piece also offers locating hole, and upper end and the die cavity of locating hole are fixed by pin, and lower end and the throw-out collar of locating hole are fixed by pin.
Described interior core is core in edge beryllium copper formula.
Evenly be fixed with the large slide block A of many groups and large slide block B on described die sinking plate, the large slide block A and the large slide block B that are distributed in die sinking plate both sides are located by spring steel ball.
The present invention has the following advantages:
1, owing to not being provided with slanting guide pillar hole on large slide block A and large slide block B, HALF piece arranging on large slide block A and large slide block B is compacter, mould has in the size of width and length direction and dwindles, take 48 chamber 3025 water cover moulds as example, die boundary dimensions narrows down to 785mm * 600mm * 453mm by 996mm * 596mm * 671mm.
2, because die boundary dimensions reduces, the cost of material decrease, although the size of large slide block A and large slide block B is longer, but the inclined-plane that will originally be arranged on large slide block A and large slide block B is set on the HALF piece, the cuboid that large slide block A and large slide block B are rule, the difficulty of processing decrease makes manufacturing cost decrease.
3, adopt spring steel ball to locate, the positioning accuracy that is positioned at the large slide block A of die sinking plate both sides and large slide block B is high, quality of fit is high when the mould open/close mould, and the appearance and size of mould reduces, the weight reducing of mould, the possibility of mould tenesmus reduces, and moves more stable, Angle Pin is not set simultaneously, and the security of mould when the folding mould is fully guaranteed.
4, large slide block A and large slide block B have not had slanting guide pillar hole, inclined-plane and HALF piece locating slot, directly for flat board adds slider guide fine positioning groove structure, the manufacturing procedure of large slide block is reduced, and processability are higher, and machining accuracy easily is guaranteed; Can guarantee its machining accuracy by the most traditional processing method car/mill processing on the HALF piece, technique is simpler, and processing cost is lower.
5, owing to there is no Angle Pin, solve traditional Angle Pin and driven the typing mechanism of slide block because of the inaccurate problem that easily causes the Angle Pin fracture in large slide block start-stop position in the folding mold process, the length of HALF piece is shorter, and its thickness thickening, make rigidity and the intensity of HALF piece improve, the processing of large slide block A and large slide block B is simple, and machining deformation is little, and the mold use life-span increases substantially.
