Description
Technical field
The present invention relates to a kind of die opening mechanism of mould.Location in specifically a kind of plastic processing open clamping.
Background technology
At present, dual-mode machine has normally been installed an intermediate die plate between the fixed form of routine and collapsible form.The mould of two standards is installed in the both sides of intermediate die plate, and on-stream two moulds replace die sinking and unload workpiece.Also alternately inject each mould the articles injection-moulded behind that is moved to injection machine.The injection moulding process of two moulds staggers mutually, yet when branch has the mould of a lot of row position, often because of the suffered resistance difference of each die joint of three template dies, occurs sequencing when causing matched moulds.
Summary of the invention
Because above-mentioned problem, the objective of the invention is to overcome the deficiencies in the prior art and defective, provide a kind of and can accurately locate, location simple in structure open clamping.
A kind of location that the present invention discloses open clamping, comprise master mold, intermediate die plate, male model and location open clamping, wherein, described intermediate die plate offers guide groove, described location open clamping comprise: the master mold pull bar, be arranged in the master mold pull bar guide groove that described intermediate die plate offers, the one end is locked on the described master mold, and its other end offers breach; The male model pull bar is arranged in the male model pull bar guide groove that described intermediate die plate offers, and the one end is locked on the described male model, and its other end offers short slot; And slide block, can left and right displacement be installed on the described intermediate die plate, between the opposite side of described male model pull bar and described master mold pull bar, under the state of mould mold closing, described slide block is fastened in the breach and described male model pull bar of described master mold pull bar.
More excellent, described location open clamping also comprise: the flexible block assembly, the one end is resisted against the inside of described intermediate die plate, the other end is resisted against the free end that is provided with short slot of described male model pull bar.
More excellent, described flexible block assembly comprises: the bullet piece is installed in the male model pull bar guide groove of described intermediate die plate; And elastic parts, be installed between the bottom of described bullet piece and described male model pull bar guide groove.
More excellent, described elastic parts is a spring.
Location of the present invention open clamping have simple in structurely, and can accurately control the die sinking of mould and the sequential scheduling advantage of matched moulds.

Fig. 2 is the cross-sectional view of the die opening state one of a preferred embodiment of the present invention.
Fig. 3 is the cross-sectional view of the die opening state two of a preferred embodiment of the present invention.
The specific embodiment
For describing technology contents of the present invention, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..
See also Fig. 1, the cross-sectional view during the mold closing state of a preferred embodiment of the present invention.This mould comprise master mold 11, intermediate die plate 12, male model 13 and location open clamping 2, wherein, described intermediate die plate 12 offers guide groove (figure does not show), described location open clamping 2 comprise: master mold pull bar 21, be arranged in the master mold pull bar guide groove that described intermediate die plate 12 offers (figure does not show), the one end is locked on the described master mold 11, and its other end offers breach 211; Male model pull bar 22 is arranged in the male model pull bar guide groove that described intermediate die plate 12 offers (figure does not show), and the one end is locked on the described male model 13, and its other end offers short slot 221; Slide block 23, can left and right displacement be installed on the described intermediate die plate 12, between the opposite side of described male model pull bar 22 and described master mold pull bar 21; And flexible block assembly 24, it comprises: bullet piece 241, be installed in the male model pull bar guide groove of described intermediate die plate, and the one end is resisted against the free end that is provided with short slot 221 of described male model pull bar 22; And spring 242, be installed between the bottom of the other end of described bullet piece 241 and described male model pull bar guide groove.Under the state of mould mold closing, described slide block 23 is fastened in the breach 211 and described male model pull bar 22 of described master mold pull bar 21, and described spring 242 is in compressive state.
See also Fig. 2, be the cross-sectional view of the die opening state one of a preferred embodiment of the present invention.In this, this mould is when die sinking, at first give the power of drawing on the described master mold 11 by board, after the breach 211 that moves to its lower end when described master mold pull bar 21 meets with described slide block 23, in the process of on board continues described master mold 11, drawing, the elastic force that described spring 242 recovers nature will promote described male model pull bar 22 and move downward, and cause its short slot 221 to promote described slide block 23 and move to breach 211 directions of described master mold pull bar 21.
Please continue to consult Fig. 3, be the cross-sectional view of the die opening state two of a preferred embodiment of the present invention.Broken away from the fixing state of described slide block 23 when described male model pull bar 22 after, draw, can make described intermediate die plate 12 be pulled away from described male model 13 fully, thereby finish the die sinking operation of this mould along with board drives in described master mold 11 continuation.
Otherwise, when matched moulds, because described slide block 23 is fastened in breach 211 places of described master mold pull bar 21, makes described master mold pull bar 21 to move down, along with described intermediate die plate 12 moves down, moving to its short slot 221 on the described male model pull bar 22 meets with described slide block 23, described master mold pull bar 21 will give the power that described slide block 23 1 moves right, and make described slide block 23 move in the described short slot 221, in this, described master mold 11 just can move down, thereby finishes the matched moulds operation of mould.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by claim of the present invention.
