Abstract
The utility model discloses a secondary stroke core-pulling structure in a refrigerator foaming mold. The secondary stroke core-pulling structure is characterized in that core-pulling blocks capable of sliding relative to expansion plates in a core-pulling direction are arranged in the middles of the expansion plates and are fixed on core-pulling block fixing seats; limiting stoppers are arranged on the expansion plates; two ends of each core-pulling block fixing seat are limited in limiting slots of a corresponding limiting stopper; the width of each limit slot depends on the relative moving distance between the core-pulling block fixing seats and the expansion plates in the core-pulling direction; the core-pulling block fixing seats can drive the expansion plates to move in the core-pulling direction through the limiting stoppers. Secondary stroke is realized through the transmission of the limiting stoppers, so that the secondary stroke core-pulling structure has the advantages that the design difficulty is reduced; the mold assembly is simple and convenient; the stability and strength are enhanced while the material consumption is reduced; the work efficiency is greatly increased.
Description
Technical field
The utility model relates to box body foaming mould.
Background technology
At present, box body foaming mould has adopted expansion mechanism mostly, and this kind of structure foaming deflection is little, is convenient to produce and safeguard, but the special or complicated refrigerator body of part is because need of production must increase a set of core-pulling mechanism in expansion mechanism, further to improve foam box quality.Conventionally the Stroke Control of expansion mechanism is in 5mm left and right, otherwise main body and the excesssive gap between plate that rises can cause foam box effect undesirable, and the stroke of core-pulling mechanism is conventionally larger, be about 15mm, but a set of executing agency of the prior art can not complete two kinds of strokes simultaneously.And box body foaming mould intracavity space is limited, in this limited space, arrange that Liang Tao mechanism not only deposits difficulty in design, when safeguarding, mould assembling has no way of doing it especially.
Summary of the invention
The utility model is for avoiding the existing weak point of above-mentioned prior art, and secondary stroke pulled core structure in a kind of refrigerator foaming mould is provided, to effectively improving product strength, guarantee to complete two kinds of strokes simultaneously, avoid waste of material, reduce costs, shorten the production cycle of product.
The utility model solves the technical scheme that its technical problem adopts:
In the utility model refrigerator foaming mould, the feature of secondary stroke pulled core structure is:
At the middle part of the plate that rises, with the form of sliding sleeve, be provided with at the piece of loosing core that can slide with respect to the plate that rises along the direction of loosing core, described in the piece of loosing core be fixed on and loose core on piece holder;
On the described plate that rises, limited block is set, described two ends of loosing core piece holder are limited in the stopper slot of described limited block, width restriction with described stopper slot is loosed core piece holder in the displacement with respect to the plate that rises along loosing core in direction, and can by limited block, drive the plate that rises in the movement along loosing core in direction by the described piece holder of loosing core.
In the utility model refrigerator foaming mould, the feature of secondary stroke pulled core structure is also:
Guide frame is set is: on the described piece holder of loosing core, by the direction setting of the loosing core piece guide rod of loosing core, coordinate the fairlead of guiding to be fixedly installed on mould bases with the described piece guide rod of loosing core.
Executing agency is set is: on the main guide post of pair of parallel setting, be provided with the push pedal that can slide along main guide post by air cylinder driven, the end of push pedal by connecting rod with described in the piece holder of loosing core hinged.
Described push pedal is upper push pedal and the lower push pedal be arrangeding in parallel, and described connecting rod relative set is upper connecting rod and lower link, and described upper push pedal and lower push pedal are by drive link interlock synchronous upper connecting rod and the lower link of driving.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model forms secondary stroke by the transmission of limited block, has reduced design difficulty, and die assembly is simple and convenient, in the Simultaneous Stabilization and the intensity that reduce material, has obtained reinforcement, has greatly improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Number in the figure: the 1a piece of loosing core, the 1b piece guide rod of loosing core, 1 holder of loosing core, 2 limited blocks, 3 fairleads, 4 cylinders, 5 mould bases, 6 main guide posts, 7 push pedals, 8 connecting rods, 9 plates that rise, 10 drive links.
The specific embodiment
Referring to Fig. 1, in the present embodiment, in refrigerator foaming mould, secondary stroke pulled core structure is:
At the middle part of the plate 9 that rises, with the form of sliding sleeve, be provided with at the piece 1a of loosing core that can slide with respect to the plate 9 that rises along the direction of loosing core, the piece of loosing core is fixed on looses core on piece holder 1.
On the main guide post 6 of pair of parallel setting, be provided with the push pedal 7 that can slide along main guide post 6 being driven by cylinder 4, the end of push pedal 7 is hinged with the piece holder 1 of loosing core by connecting rod 8.
On the piece holder 1 of loosing core, by the direction setting of the loosing core piece guide rod 1b of loosing core, coordinate the fairlead 3 of guiding to be fixedly installed on mould bases 5 with the piece guide rod 1b of loosing core.
On the plate 9 that rises, limited block 2 is set, the loose core two ends of piece holder are limited in the stopper slot of limited block 2, width restriction with stopper slot is loosed core piece holder 1 in the displacement with respect to the plate that rises along loosing core in direction, and can by limited block 2, drive the plate that rises in the movement along loosing core in direction by the piece holder 1 of loosing core.
In concrete enforcement, in order to guarantee the stability of mechanism action, and gain in strength, upper push pedal and the lower push pedal of push pedal 7 for be arrangeding in parallel is set, connecting rod 8 relative set are upper connecting rod and lower link, and upper push pedal and lower push pedal are by drive link 10 interlocks synchronous upper connecting rod and the lower link of driving.
In the present embodiment, cylinder stretches out, and by the holder of loosing core, has driven the piece of loosing core to move inward together with the plate that rises.If casing is loosed core, piece amount of contraction is 14.5mm, the plate amount of contraction that rises is 4.5mm, to be set to overall shrinkage amount be 14.5mm to linkage, be that in limited block, to loose core between the motor area of holder be 14.5mm, when cylinder stretches out, connecting rod pulls the holder of loosing core to retract, in the holder laminating stopper slot of loosing core during inner side limiting-position face, stroke reaches 10mm, and cylinder stroke does not put in place, so the holder of loosing core rises by plate together to reclaiming contracting 4.5mm by drive.Otherwise, when foam box is produced, cylinder pulls push pedal to decline, connecting rod drive loose core holder and the piece of loosing core protruding, in loose core holder and stopper slot outside confined planes while fitting, stroke is 10mm, continuation action along with cylinder, the holder of loosing core drives the plate that rises together outwards to continue to stretch out 4.5mm by limited block, and cylinder puts in place, can start foaming work.
