Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated。Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model。
As shown in Figure 1, a kind of easy-open lid injection molding, including centring ring 1, described centring ring 1 left end is connected to top clamping plate 2, described top clamping plate 2 is connected to the first core 4 by the first screw 3, described first core 4 is connected to spacing screw rod 6 by spring 5, described spacing screw rod 6 is connected to the second core 8, annular core 7 it is provided with between described second core 8 and the first core 4, described second core 8 is connected to sealing ring 11 by the second screw 10, described sealing ring 11 is received water pipe head 12, described water pipe head 12 is connected with release link 13 and support column 14, described support column 14 has been connected below Bottom clamp plate 15, described Bottom clamp plate 15 right-hand member upper surface is connected to push pedal 16, described push pedal 16 is connected to ejector pin retaining plate 17, described ejector pin retaining plate 17 connects by support plate 19, described support plate 19 is connected to sprue puller 20, described sprue puller 20 is connected to the second core fixing plate 21, described second core fixing plate 21 is provided with guide pillar 22, described guide pillar 22 is connected to guide pillar push pedal 23, described guide pillar push pedal 23 is connected to the first core fixing plate 24, described first core fixing plate 24 is provided with backing plate 26, described backing plate 26 is connected to fixing plate 27, described centring ring 1 is connected with gate bush 28。
On above-described embodiment preferably, it is provided with copper pipe 9 in described annular core 7。
On above-described embodiment preferably, it is provided with cushion block 18 between described ejector pin retaining plate 17 and support plate 19。
On above-described embodiment preferably, described guide pillar 22 is provided with guide pin bushing 25。
During this utility model die sinking, move after injection machine slide block, the compression spring being arranged between the backing plate of core fixing plate and annular core flicks, die joint I opens, be arranged on the core in the middle of top clamping plate and core fixing plate, Angle Pin is stayed above die joint I motionless, compression spring moves after promoting backing plate, and annular core 7 and core fixing plate are moved rearwards by。Slide block on core fixing plate moves along Angle Pin, completes that screw thread lobe is box-like looses core。After whorl side has been loosed core, core separates with annular core, becomes hollow in the middle of the annular distance of pull-tab。Injection machine slide block moves after continuing, spacing screw rod and pad contact, backing plate and core fixing plate move after stopping, die joint II opens, plastic is because self lower end annular barb and inverted cone sprue puller stay dynamic model, and the pull-tab annular distance of plastic upper end becomes hollow, because leaving deformation space, the ring part shrinkage deformation forced stripper mechanism of pull-tab, extracts out by force from mould；After the complete die sinking of mould, injection machine push rod promotes mould pushing-out structure, and push pedal is forced out plastic from core, completes the demoulding。During matched moulds, injection machine slide block moves forward, and push pedal and release link complete ejecting mechanism and reset, and Angle Pin completes slide block and resets, and upper and lower double; two guiding ensure the accurate guide-localization of template, and matched moulds completes, and injection starts, and enters next cycle of operation。
Based on above-mentioned, this utility model designs 1 mould 4 chamber injection mold structure, have employed order Enforced stripping structure and cover half sequential code system structure, and whole secondary mould structure is reasonable, and reliable in action, the plastic demoulding is smooth。
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model。
