The specific embodiment
are come technical scheme of the present invention is done further to set forth below in conjunction with accompanying drawing and concrete embodiment.
are depicted as a kind of inner container of icebox structural representation referring to Fig. 1-4; Wherein, This inner container of icebox comprises the cabinet body 3 ' with inner chamber; Have the protuberance 4 ' of protrusion laterally on one side end of cabinet body 3 ',, can not directly vertically carry out the demoulding behind the mould molding because protuberance 4 ' outwards protrudes.
are depicted as the vacuum forming mould that is used to produce above-mentioned inner container of icebox of a specific embodiment of the present invention referring to Fig. 5-7.This mould comprises die shoe 1; Be permanently connected on the die shoe 1 and be provided with the forming body with inner chamber 2 that can form cabinet body 3 '; Be positioned on the die shoe 1 on the side end of forming body 2 and also be provided with the forming slide 3 that can form protuberance 4 '; Be connected through first cylinder 4 between forming slide 3 and the die shoe 1, the setting of first cylinder 4 is mainly used in when after this mould is accomplished the moulding of product, carrying out the demoulding in the inner chamber that forming slide 3 is pulled to forming body 2 with conveniently stripped completion.First cylinder 4 comprise first cylinder body 41 with can be along first expansion link 42 of the axial stretching of first cylinder body 41, in the present embodiment, first cylinder body 41 is fixedly connected with die shoe 1, the external part of first expansion link 42 and forming slide 3 are fixedly connected.The bottom end face of the axial line of first expansion link 42 and forming body 2 tilts setting; The angle of its inclination is being advisable in pulling forming slide 3 to forming body 2 inner chambers when first expansion link 42 shortens; In the present embodiment, be 45 ° of settings between the bottom end face of the axial line of first expansion link 42 and forming body 2.
referring to shown in Fig. 5-7, and are more steady when guaranteeing first cylinder, 4 pulling forming slides 3, between die shoe 1 and forming slide 3, also are provided with at least one group of guiding mechanism 5, and here guiding mechanism 5 has four groups.Guiding mechanism 5 is made up of guide holder 51 and lead 52; Wherein guide holder 51 is fixedly connected and is arranged on the die shoe 1; The axial line that offers the bearing of trend and first expansion link 42 on the guide holder 1 parallels the groove of setting; One end of lead 52 can be inserted ordinatedly in the above-mentioned groove and can in above-mentioned groove, be slided by the bearing of trend along groove, the other end of lead 52 then with forming slide 3 setting that is fixedly connected.For example, groove can adopt cylinder shape groove, and the axial line of the columniform axial line and first expansion link 42 parallels setting, and first expansion link 42 also is a cylindrical bar.First cylinder body 42 can be arranged on the die shoe 1 through link with guide holder 51 integratedly.
are referring to shown in Figure 5; This mould also comprises the auxilliary die holder 6 that can be arranged on up and down on the die shoe 1; The outboard end that is positioned at forming slide 3 on the auxilliary die holder 6 is provided with second cylinder 72; Second cylinder comprise be fixedly connected second cylinder body be arranged on the auxilliary die holder 6 and along second Boring mill to second expansion link that can stretch; The axial line along continuous straight runs of second expansion link distributes; The external part of second expansion link also is connected with one and can when second expansion link stretches out, matches with push-off pin 71, the second cylinders 72 and the auxilliary mold forming mechanism 7 of push-off pin 71 formation of the moulding of end face outside the realization protuberance 4 ', promptly when processing and forming with the outboard end of forming slide 3; The work of second cylinder 72 makes the elongation of second expansion link, does 71 and releases on the outside end face that the material that will be used for processing and forming is pressed on forming slide 3 and accomplish moulding thereby drive to release.In order to make push-off pin 71 held stationary when along continuous straight runs moves; Can on auxilliary die holder 6, offer the chute that an along continuous straight runs extends; Can penetrate in the above-mentioned chute and along continuous straight runs slides in this chute guide pillar through connect one in the other end of push-off pin 71 again, the cooperation through guide pillar and chute realizes that push-off pin 71 keeps the mobile of along continuous straight runs.
Below set forth in detail the course of work of present embodiment:
are referring to shown in Figure 5; The vacuum forming mould of present embodiment is when being used for that inner container of icebox carried out moulding; At first first expansion link 41 elongation of first cylinder 4 is pushed out to forming slide 3 on the side end of forming body 2 can mold the counterdie of above-mentioned inner container of icebox with forming body 2 common formation, and the sheet material that will be used for processing and forming again is sent to shaping station, promptly is sent between the patrix (not shown) and counterdie of top mold frame; Auxilliary die holder 6 vertically descends; Die shoe 1 is up to be cooperated with patrix the sheet material pressing after after technology such as frothing, vacuumize, 72 work of second cylinder, and the outside end face that the elongation of second expansion link makes push-off pin 71 push forming slide 3 to makes the global formation of inner container of icebox; Through pressurize, after the technology such as the vacuum of cooling off, disappear, obtain the inner container of icebox shaped article.At this moment, 72 work of second cylinder, second expansion link shortens pulls back push-off pin 71; Unclamp the compressing of inner container of icebox shaped article protuberance outside end face, 4 work of first cylinder, first expansion link 41 shortens vertically; Under the guiding of lead 52, forming slide 3 is along in the inner chamber that axially is pulled to forming body 2 of first expansion link 41, and at this moment die shoe 1 is descending; Forming body 2 and forming slide 3 just spin off from the inner chamber of inner container of icebox shaped article, have realized the demoulding.
in sum; The vacuum forming mould of inner container of icebox of the present invention, through first cylinder 4 when the demoulding with forming slide 3 along in the oblique inner chamber of drawing in forming body 2 with conveniently stripped, simplified the structure of mould; Reduced the manufacturing cost of mould; Simultaneously also make the mould reliability of operation be improved, the space at the place, plane, top of forming body 2 increases, and is convenient to arrange cooling water channel; This makes the temperature at this mould top when moulding to descend apace, has improved the shaped article quality and the production efficiency of inner container of icebox.In addition, and forming slide 3 adopts and is wholely set, and the plastic uptake vestige reduces on the product, and aesthetics is improved.
