Abstract
A de-molding mechanism of a vacuum forming mould is characterized in that the de-molding mechanism is designed as a parallelogram linkage formed by a core-knockout block connecting rod, a driving connecting bar in parallel to the core-knockout block connecting rod, a left rocker and a right rocker respectively articulated between the aforementioned two bars. Each core-knockout block is firmly arranged on the core-knockout block connecting rod respectively based on relevant position. On the core-knockout block connecting rod, a guide pole is arranged in parallel to the moving direction of the core-knockout block. A guide sleeve is fixed on the machine frame and forms a sliding cooperation with the guide rod. The driving connecting bar is linked with the piston rod of an air cylinder, and forms a sliding fit with a slide bar base fixed on the main body in the direction vertical to the moving direction of the core-knockout block. The utility model has a simple structure, can reduce cost, and can mainly guarantee the synchronized motions and accurate cooperation among all the core-knockout blocks, thus guaranteeing the successful de-molding and improving the product quality.
Description
Technical field
The utility model relates to demouding mechanism for vacuum plastic-absorbing forming mould, more specifically says so such as the mould emptier of inner container of icebox vacuum forming mould.
Background technology
The inner container of icebox vacuum forming mould mainly is the thermoplastic plate to be frothed it is drawn together by heating stretch, and extracts the air in the mold cavity out, forms vacuum, makes plate be adsorbed on die surface, again through supercooling, moulding, blows, the demoulding obtains required product.In the concrete operations,, mould emptier need be set on mould for the smooth demoulding, such as, be applied in the core-pulling device in the inner container of icebox vacuum forming mould.In the prior art, the version that refrigerator door liner is hung the boss core-pulling mechanism of bottle stand, shelf be by a cylinder about drive opposite to each other on the direction of its axis two loose core, thereby two of driven in synchronism are loosed core and are finished demoulding action.The existing problem of this version is, when in the door courage a plurality of boss being arranged, must many cover cylinders be set correspondence, and between many cover cylinders, be difficult on the one hand that guaranteeing respectively looses core keeps strokes, on the other hand, because dimensionally inconsistent of transmission mechanism exists the problem that is difficult to cooperatively interact between respectively loosing core.These problems may cause demoulding difficulty, also may bring product quality problem.Moreover, overlap being provided with of cylinder more and improved die cost, cause mould structure complexity, increased the weight of mould.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point; provide a kind of simple in structure; reduce cost, and the demouding mechanism for vacuum plastic-absorbing forming mould of keeping strokes between mainly can guaranteeing respectively to loose core and accurately cooperating, thereby guarantee that the demoulding is smoothly to improve the quality of products.
The utility model technical solution problem adopts following technical scheme.
The design feature of the utility model demouding mechanism for vacuum plastic-absorbing forming mould be the setting of described mould emptier be by the piece connecting rod of loosing core, with the parallel drive link of piece connecting rod of loosing core, and be hinged on the left rocking bar of loosing core between piece connecting rod and the drive link respectively and right rocking bar constitutes parallelogram lindage, the piece of respectively loosing core is arranged on the piece connecting rod of loosing core by separately fixed-site, on the described piece connecting rod of loosing core, the moving direction that is parallel to the piece of loosing core is provided with lead, guide pin bushing be fixed on the main body and and lead formation be slidingly matched; Drive link is a slide bar, and links by the piston rod of interlock plate and cylinder, and drive link is slidingly matched with the slider block formation that is fixed on the main body on perpendicular to the moving direction of the piece of loosing core.
Design feature of the present utility model also is with the cylinder to be the center; the bilateral symmetry that is positioned at cylinder is provided with two groups of mould emptiers; the interlock plate is fixedly installed between the drive link in two groups of mould emptiers that are parallel to each other, and described interlock plate and cylinder piston rod are fixedly connected.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the piece of respectively loosing core in the utility model is co-located on the piece connecting rod of loosing core, reliable synchronization action between the piece has guaranteed respectively to loose core, cooperate the accurate control of piece on himself size and dimension of respectively loosing core, can improve demoulding success rate greatly, improve the quality of products.
2, the utility model has simplified mould structure greatly, and has improved the reliability of demoulding work whereby, reduces die cost, alleviates mold weight.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 side view.
Number in the figure: 1 guide pin bushing, 2 leads, 3a left side rocking bar, the right rocking bar of 3b, 4 slider blocks, 5 drive link, 6 piece connecting rod, 7 interlock plates, 8 cylinders, 9 piece of loosing core of loosing core.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings:
The specific embodiment
Referring to Fig. 1, Fig. 2, by the piece connecting rod 6 of loosing core, the drive link 5 parallel with the piece connecting rod 6 of loosing core, and be hinged on the left rocking bar 3a of loosing core between piece connecting rod 6 and the drive link 5 respectively and right rocking bar 3b constitutes parallelogram lindage, the piece 9 of respectively loosing core is arranged on the piece connecting rod 6 of loosing core by separately fixed-site, on the piece connecting rod 6 of loosing core, the moving direction that is parallel to the piece 9 of loosing core is provided with lead 2, guide pin bushing 1 be fixed on the main body and and lead 2 formation be slidingly matched; Drive link 5 is a slide bar, and passes through the piston rod interlock of interlock plate 7 and cylinder 8, and drive link 5 is slidingly matched with slider block 4 formations that are fixed on the main body on perpendicular to the moving direction of the piece 9 of loosing core.
In concrete the enforcement; according to the shape of mould, can be set to cylinder 8 is the center, and the bilateral symmetry that is positioned at cylinder 8 is provided with two groups of mould emptiers; interlock plate 7 is fixedly installed between the drive link 5 in two groups of mould emptiers that are parallel to each other, and interlock plate 7 is fixedly connected with cylinder piston rod.
The course of work is as follows:
During vacuum suction moulding, cylinder 8 air inlets promote piston rod and stretch out left, and drive drive link 5 is moved to the left in slider block 4, when drive link 5 is moved to the left, drive left rocking bar 3a and right rocking bar 3b rotates, drive thus and loose core piece connecting rod 6 in translation on lead 2 directions, the piece 9 of loosing core is pushed out with the moving ahead of piece connecting rod 6 of loosing core and operating position when being in moulding; Moulding finishes, for the smooth demoulding, cylinder 8 air inlets in the other direction, promote piston rod and move backward, pulling connecting plate 7 and drive link 5 oppositely move at slider block 4, and drive link 5 is reverse when mobile, spur left rocking bar 3a and right rocking bar 3b backward rotation, thereby drive the piece connecting rod 6 oppositely translation on lead 2 directions of loosing core, the piece 9 of loosing core is finished and is loosed core with the reverse translation withdrawal of the piece connecting rod 6 of loosing core.
