Referring to fig. 1 to 11, in an embodiment of the present invention, there is provided an expansion and contraction mold of a large stroke subassembly for forming a kitchen frame 100, the kitchen frame 100 including a convex cavity 110, the expansion and contraction mold including:
a main fixing plate 210 which is an installation base of the collapsible mold;
a main fixing frame 220 connected to an outer side surface of the main fixing plate 210;
the driving frame 230 is connected to a surface of the main fixing frame 220 away from the main fixing plate 210, and the driving frame 230 is a function foundation of an external driving structure;
a main collapsible member 310 mounted to the main fixing plate 210 for molding the kitchen frame 100;
a first driving assembly 320 mounted to the main fixing plate 210 for driving the main collapsible assembly 310;
a first fixing seat 400 disposed at an inner side of the main fixing plate 210;
the second driving cylinder 500 comprises a second cylinder body 510 and a second driving rod 520 arranged in the second cylinder body 510, and one end of the second cylinder body 510, which is far away from the second driving rod 520, is hinged to the first fixed seat 400;
a parallel guide rail group 600 disposed inside the main fixing plate 210;
a sub-collapsible member 700 slidably disposed on the parallel guide rail set 600, the second driving rod 520 being connected to the sub-collapsible member 700, the sub-collapsible member 700 being used for processing the convex cavity 110;
a third driving assembly installed on the sub-collapsible assembly 700 for driving the sub-collapsible assembly 700;
a mold housing cooperating with the main collapsible member 310 and the sub collapsible member 700.
The external driving structure drives the whole driving frame 230 to move, and the driving frame 230 drives the main fixing frame 220 and the main fixing plate 210 to move, so that all the structural members mounted on the main fixing plate 210 move along with the main fixing frame. The first drive assembly 320 controls the operation of the main collapsible assembly 310. Taking the main collapsible assembly 310 as an example, the main collapsible assembly 310 includes a guide pillar assembly 311 vertically installed, two sliding plates 312, a plurality of fixing rods 313, a plurality of collapsible plate installation rods 314 matched with the fixing rods 313, a plurality of limit guide pillar assemblies 315, and a plurality of collapsible plates 316; the sliding plates 312 can be driven up and down on the guide post assembly 311 by the first driving assembly 320, the fixing rod 313 is connected between the two sliding plates 312, the fixing rod 313 and the collapsible plate mounting rod 314 form a connecting rod connection, and the guide post assembly 315 is limited so that the collapsible plate mounting rod 314 can only move in the direction perpendicular to the guide post assembly 311; that is, when the first driving assembly 320 drives the sliding plate 312 to move on the guide post assembly 311, the fixing rod 313 moves up and down together, the fixing rod 313 and the collapsible plate mounting rod 314 are connected to move the collapsible plate mounting rod 314 together, but the position-limiting guide post assembly 315 enables the collapsible plate mounting rod 314 to move only in the direction perpendicular to the guide post assembly 311, and thus the collapsible action of the main collapsible assembly 310 is realized. The corresponding sub-collapsible member 700 is similar in structure to the main collapsible member 310 described above. When the cam cavity 110 is formed, the sub-collapsible member 700 is extended out of the main collapsible member 310 by the second driving cylinder 500; when demolding is to be performed, the sub-collapsible member 700 retracts the main collapsible member 310 by the second driving cylinder 500; wherein the parallel guide rail set 600 functions to limit the moving direction of the sub-collapsible member 700. The mold housing cooperates with the main collapsible member 310 and the sub collapsible member 700 to co-form the galley frame 100.
In the utility model, the outer convex cavity 110 is processed by the sub-expansion and contraction assembly 700 connected with the second driving cylinder 500, so that the demoulding process of the outer convex cavity 110 is conveniently realized; and the second driving cylinder 500 is connected to the first fixing seat 400 in a hinged manner, so that the accuracy of the installation position of the second driving cylinder 500 is reduced, and a small position error in the installation in the vertical direction can be adapted by the above-mentioned hinged structure.
Referring to fig. 9 to 11, in one embodiment, a second fixing seat 410 is further disposed on an inner side of the main fixing plate 210, and the second fixing seat 410 elastically supports an end of the second cylinder block 510 close to the second driving cylinder 500.
In the present invention, an end of the second cylinder 510 remote from the second driving rod 520 is hinged to the first fixed base 400, and the second driving rod 520 is connected to the sub-collapsible assembly 700. There are only two fixed points of force applied to the entire second driving cylinder 500, and in the case that the second driving cylinder 500 has a large mass, the possibility of deformation of the second driving rod 520 is increased, and the hinged characteristic of the second cylinder 510 also makes the force applied to the second driving rod 520 large. In the present embodiment, the second fixing base 410 elastically supports the second cylinder block 510, so that the force bearing points of the second driving cylinder 500 are increased to three while the minute swing of the second driving cylinder 500 is not affected, and the supporting position of the second fixing base 410 is in the middle of the second driving cylinder 500, the probability of the deformation of the second driving rod 520 is significantly reduced.
Referring to fig. 11, in an embodiment, the second fixing seat 410 includes a second base 411, a spiral casing 413, and a contact 412, the spiral casing 413 is connected to the second base 411 and forms a mounting cavity therebetween, the contact 412 is disposed in the mounting cavity and partially penetrates through an end of the spiral casing 413 away from the second base 411, an elastic member 414 is disposed between the contact 412 and the second base 411, and an end of the contact 412 away from the second base 411 is used for elastically supporting the second driving cylinder 500.
In this embodiment, a simple manner is provided, which realizes the elastic support of the second fixing base 410 to the second cylinder 510.
In one embodiment, the main fixing plate 210 is provided with guide members at positions on both sides of the parallel guide rail set 600 in the width direction, and the guide members guide the movement direction of the sub-collapsible member 700 to be along the length direction of the parallel guide rail set 600.
The parallel guide rail set 600 has a contradiction to the limitation of the sub-collapsible assembly 700, and if the size matching between the two is tight, the small deformation can destroy the guiding effect of the parallel guide rail set 600; if the size matching between the two is loose, the guiding effect is reduced. In this embodiment, in order to reduce the possibility of damage to the parallel guide rail set 600 by the sub-collapsible member 700, two guide members are added.
Referring to fig. 7-8, in one embodiment, the guide assembly is a hinged two-piece folding bar 610. Compared with the parallel guide rail set 600 assembly, the possibility of damage to the two-section folding rod 610 is low, and the size or strength performance of the two-section folding rod 610 can be simply guaranteed.
In one embodiment, the guiding assembly includes a guide rod and a guide base, the guide rod is connected to the sub-collapsible assembly 700, the guide base is connected to the main fixing plate 210, a through hole matched with the guide rod is formed in the guide base, and guiding is achieved through matching of the guide rod and the through hole.
The limiting directions of the guide rod and the guide seat are consistent with the length direction of the parallel guide rail group 600, so that the guide assembly can play a more smooth guide role.
In one embodiment, the guide rods are detachably connected to the sub-collapsible assembly 700 by bolts.
The bolt mode improves the installation performance of the guide rod.
In one embodiment, the guide is detachably coupled to the main fixing plate 210 by bolts.
The bolt mode improves the installation performance of the guide seat.
In one embodiment, the second drive cylinder 500 is hydraulically driven.
The hydraulic drive type has larger power and stable drive process.
In summary, in the collapsible mold of the large-stroke subassembly provided by the utility model, the outer convex cavity 110 is processed by the sub-collapsible assembly 700 connected with the second driving cylinder 500, so that the demolding process of the outer convex cavity 110 is conveniently realized; and the second driving cylinder 500 is connected to the first fixing seat 400 in a hinged manner, so that the accuracy of the installation position of the second driving cylinder 500 is reduced, and a small position error in the installation in the vertical direction can be adapted by the above-mentioned hinged structure.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures or equivalent flow transformations made by using the contents of the specification and the drawings, or applied directly or indirectly to other related technical fields, are included in the scope of the present invention.
