Detailed description of the invention
below in conjunction with accompanying drawing and specific embodiment, technical scheme of the present invention is further elaborated.
be depicted as a kind of refrigerator liner structure schematic diagram referring to Fig. 1-4, wherein, this inner container of icebox comprises the cabinet body 3 ' with inner chamber, on one side end of cabinet body 3 ', there is the protuberance 4 ' protruding laterally, because protuberance 4 ' is outwardly, after mould molding, can not directly vertically carry out the demoulding.
be depicted as the vacuum forming mould for the production of 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, on die shoe 1, be permanently connected and be provided with the forming body with inner chamber 2 that can form cabinet body 3 ', on die shoe 1, be positioned on a side end of forming body 2 and be also provided with the forming slide 3 that can form protuberance 4 ', between forming slide 3 and die shoe 1, be connected by the first cylinder 4, when the setting of the first cylinder 4 is mainly used in carrying out the demoulding after this mould completes the moulding of product, forming slide 3 be pulled in the inner chamber of forming body 2 with conveniently stripped completing.The first cylinder 4 comprises the first cylinder body 41 and can be along the first expansion link 42 of the axial stretching of the first cylinder body 41, and in the present embodiment, the first cylinder body 41 is fixedly connected with die shoe 1, and the external part of the first expansion link 42 and forming slide 3 are fixedly connected.The bottom end face of the axial line of the first expansion link 42 and forming body 2 tilts setting, the angle of its inclination pulling forming slide 3 to be advisable to forming body 2 inner chambers in the time that the first expansion link 42 shortens, in the present embodiment, between the axial line of the first expansion link 42 and the bottom end face of forming body 2, be 45 ° of settings.
shown in Fig. 5-7, more steady when ensureing that the first cylinder 4 pulls forming slide 3, between die shoe 1 and forming slide 3, be also provided with at least one group of guiding mechanism 5, 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 with and is arranged on die shoe 1, on guide holder 1, offer bearing of trend parallels setting groove with the axial line of the first expansion link 42, one end of lead 52 can be inserted ordinatedly in above-mentioned groove and can in above-mentioned groove, be slided by the bearing of trend along groove, the other end of lead 52 with forming slide 3 setting that is fixedly connected.For example, groove can adopt cylinder shape groove, and columniform axial line parallels setting with the axial line of the first expansion link 42, and the first expansion link 42 is also cylindrical bar.The first cylinder body 42 and guide holder 51 can be arranged on die shoe 1 integratedly by link.
shown in Figure 5, this mould also comprises the auxiliary die holder 6 that can be arranged on up and down on die shoe 1, on auxiliary die holder 6, be positioned in the outboard end of forming slide 3 and be provided with the second cylinder 72, the second cylinder comprises and is fixedly connected with the second cylinder body of being arranged on auxiliary die holder 6 and along the second Boring mill to second expansion link that can stretch, the axial line along continuous straight runs of the second expansion link distributes, the external part of the second expansion link is also connected with a push-off pin 71 that can match to realize the moulding of protuberance 4 ' outside end face in the time that the second expansion link stretches out with the outboard end of forming slide 3, the second cylinder 72 and push-off pin 71 form auxiliary mold forming mechanism 7, in the time of processing and forming, the second cylinder 72 work are extended the second expansion link, thereby drive and release dry 71 and release and complete moulding by being pressed on for the material of processing and forming on the outside end face of forming slide 3.In order to make push-off pin 71 held stationary in the time that along continuous straight runs moves, can on auxiliary die holder 6, offer the chute that an along continuous straight runs extends, by the guide pillar of along continuous straight runs slip in the other end of push-off pin 71 connection one can penetrate above-mentioned chute and in this chute, realize by the cooperation of guide pillar and chute the movement that push-off pin 71 keeps along continuous straight runs again.
below elaborate the course of work of the present embodiment:
shown in Figure 5, the vacuum forming mould of the present embodiment is when carrying out moulding to inner container of icebox, first the first expansion link 41 of the first cylinder 4 extends forming slide 3 is pushed out on a side end of forming body 2 to can mold the counterdie of above-mentioned inner container of icebox with the common formation of forming body 2, again the sheet material for processing and forming is sent to shaping station, be sent between the patrix (not shown) and counterdie of top mold frame, auxiliary die holder 6 vertically declines, die shoe 1 is up coordinate with patrix to after sheet material pressing through frothing, vacuumize etc. after technique, the second cylinder 72 is worked, the second expansion link extends the outside end face that makes push-off pin 71 push forming slide 3 to and makes the global formation of inner container of icebox, through pressurize, cooling, disappear after the techniques such as vacuum, obtain inner container of icebox shaped article.At this moment, the second cylinder 72 is worked, the second expansion link shortens pulls back push-off pin 71, unclamps the compressing of end face outside inner container of icebox shaped article protuberance, and the first cylinder 4 is worked, the first expansion link 41 shortens vertically, under the guiding of lead 52, forming slide 3 is along in the inner chamber that is axially pulled to forming body 2 of the 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, by the first cylinder 4 when the demoulding by forming slide 3 along in the oblique inner chamber of drawing in forming body 2 with conveniently stripped, simplify the structure of mould, reduce the manufacturing cost of mould, also make mould reliability of operation be improved simultaneously, the space at the plane place, top of forming body 2 increases, be convenient to arrange cooling water channel, this can decline the temperature at this mould top in the time of moulding rapidly, has improved shaped article quality and the production efficiency of inner container of icebox.In addition, and forming slide 3 adopts and is wholely set, and on product, plastic uptake vestige reduces, and aesthetics is improved.
above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
