Detailed description of the invention
It is described further of the present utility model below in conjunction with accompanying drawing.
Embodiment 1
Such as Fig. 1, shown in Fig. 2, a kind of die assembly, it includes backing plate 41, positioning needle 49 fixes plate, cope match-plate pattern 46, housing, the upper surface of described backing plate 41 is provided with positioning needle 49 and fixes plate, the bottom face of described backing plate 41 is provided with spring 410, what described positioning needle 49 fixed the upper surface of plate is provided centrally with release link 43, described release link 43 is through the center of compacted under block 48, the inside of described compacted under block 48 is run through positioning needle 49, compacted under block 48 is stretched in one end of described positioning needle 49, the other end of described positioning needle 49 stretches into positioning needle 49 and fixes plate, the described left end on the upside of compacted under block 48 is provided with side core A44, described side core A44 and is connected to side core B47, and the upside of described side core B47 is provided with forming blocks 45, and the arranged outside of described upper forming blocks 45 has cope match-plate pattern 46.
As shown in Figure 3, Figure 4, mould structure solves following problem: metal shell is the location difficulty problem that circle causes, plastic be entirely metal shell surrounded cause enter gate location select permeability, plastic wall is relatively thin to be caused stream not freely to be difficult to complete molding to fly problem, its simple in construction, location structure are few, cost is low, efficiency is high, die joint selects rationally, but the problem of housing location difficulty is not still solved, this utility model adopts positioning needle to coordinate fabrication hole, and housing is effectively positioned by connecting shaping block, detent mechanism is simply effective.
When this utility model uses, during die sinking, under the effect of spring 410 elastic force, positioning needle 49 and release link 43 are fixed in positioning needle 49 and are moved up under the drive of plate; Fixing positioning needle 49 when plate contacts with compacted under block 48 when positioning needle 49 and stop mobile, now positioning needle 49 protrudes forming blocks, can positioning needle 49 be penetrated in the fabrication hole of housing, relies on positioning needle 49 and compacted under block 48 common by housing location; During matched moulds, cope match-plate pattern 46 contacts with release link 43, and positioning needle 49 is pressed multiple return; When complete mold closing, positioning needle 49 departs from housing, for ensureing the unobstructed offer advantage into cast gate, and now housing and upper and lower type block close contact, the location of housing is ensured by upper and lower type block completely; Die sinking again, positioning needle 49 relies on elastic force to be ejected by assembly, completes whole work process.
During the demoulding, this mould does not arrange mould emptier specially, but makes full use of construction features and the mould emptier of assembly, utilizes positioning needle 49 to carry out the demoulding dexterously; Figure 4, it is seen that after matched moulds, positioning needle 49 is deviate from from fabrication hole, and during injection mo(u)lding, fabrication hole is filled with by plastics; During die sinking, positioning needle 49 resets under the effect of spring 410; Because fabrication hole is filled, so positioning needle 49 drives part to deviate from from die cavity; Owing to die cavity is semicircular structure, therefore the power of positioning needle 49 is fully able to the guarantee smooth demoulding of part; Mould emptier make use of the construction features of positioning needle 49 dexterously, makes positioning needle 49 both do part location and uses, makees again push rod and use, eliminate a set of special ejecting mechanism, make mould structure be greatly simplified, reduce die cost, improve the reliability of mould; Total, this utility model have stable action reliable, without mould emptier, manufacture advantage convenient, that cost is low, qualification rate is high, good in economic efficiency.
Embodiment 2
Such as Fig. 1, shown in Fig. 2, a kind of die assembly, it includes backing plate 41, positioning needle 49 fixes plate, cope match-plate pattern 46, housing, the upper surface of described backing plate 41 is provided with positioning needle 49 and fixes plate, the bottom face of described backing plate 41 is provided with spring 410, what described positioning needle 49 fixed the upper surface of plate is provided centrally with release link 43, described release link 43 is through the center of compacted under block 48, the inside of described compacted under block 48 is run through positioning needle 49, compacted under block 48 is stretched in one end of described positioning needle 49, the other end of described positioning needle 49 stretches into positioning needle 49 and fixes plate, the described left end on the upside of compacted under block 48 is provided with side core A44, described side core A44 is connected to side core B47, the upside of described side core B47 is provided with forming blocks 45, the arranged outside of described upper forming blocks 45 has cope match-plate pattern 46, it is integral type structure that described positioning needle 49, release link 43, positioning needle 49 fix plate, described positioning needle 49, release link 43, positioning needle 49 are fixed the integral structure of plate composition and are arranged between compacted under block 48 and cope match-plate pattern 46, and described positioning needle 49 penetrates the fabrication hole 0.1mm of housing.
As shown in Figure 3, Figure 4, mould structure solves following problem: metal shell is the location difficulty problem that circle causes, plastic be entirely metal shell surrounded cause enter gate location select permeability, plastic wall is relatively thin to be caused stream not freely to be difficult to complete molding to fly problem, its simple in construction, location structure are few, cost is low, efficiency is high, die joint selects rationally, but the problem of housing location difficulty is not still solved, this utility model adopts positioning needle to coordinate fabrication hole, and housing is effectively positioned by connecting shaping block, detent mechanism is simply effective, positioning needle 49 of the present utility model, release link 43, it is integral type structure that positioning needle 49 fixes plate, positioning needle 49, release link 43, positioning needle 49 is fixed the integral structure of plate composition and is arranged between compacted under block 48 and cope match-plate pattern 46, positioning needle 49 penetrates the fabrication hole of housing, positioning needle 49 penetrates the fabrication hole 0.1mm of housing, the detent mechanism of whole integral structure can freely-movable in the spatial dimension that compacted under block 48 and cope match-plate pattern 46 are formed, the effect of positioning needle 49 is very special, not only play the role of positioning, but also act the effect of ejecting, also can effectively prevent the excessive glue in injection process simultaneously, positioning needle 49 plays the role of positioning through the fabrication hole of housing, in the process of matched moulds, the relative motion of housing and positioning needle 49 it is easily caused due to the motion of dynamic model, cause positioning unsuccessfully, therefore the reasonable clearance of conservative control positioning needle 49 and fabrication hole is wanted, it is prevented that the housing play in matched moulds process,Simultaneously because the Main Function of positioning needle 49 is in matched moulds process, housing to be positioned, matched moulds to exit fabrication hole after terminating, position is provided for cast gate, therefore when the displacement of positioning needle 49 to guarantee die sinking, positioning needle 49 exceeds housing 2��3mm, during matched moulds, positioning needle 49 only needs to wear fabrication hole 0.1mm under people's housing, so namely can guarantee that housing is accurately positioned, and cast gate is smooth and easy, can prevent again molten plastic from overflowing from fabrication hole, it is ensured that product quality; Total, this utility model have stable action reliable, without mould emptier, manufacture advantage convenient, that cost is low, qualification rate is high, good in economic efficiency.
