Description
Technical field
The utility model relates to the mould emptier of refrigerator body foaming molding mold.
Background technology
After outside plate work piece of refrigerator body and the assembly unit of refrigerator plastics inner bag, needing the heat-insulation and heat-preservation material of the high expansion rate of injection between inner bag and plate work piece is expanding foam solution.Because the expanding foam solution expansion rate is too big, therefore outside six faces of refrigerator body must be clamped casing with anchor clamps when refrigerator foaming, after expanding foam solution from expanding the casing external compression are out of shape preventing.And the inner bag of box house is because material is plastics, and therefore easy deformation more after the foaming need come inner container of icebox is supported with refrigerator foaming mould aluminum mold, prevents the distortion of inner bag position.In view of the inner bag shape is complicated, when foaming, some concave surface position to support, and therefore the demoulding smoothly again during the demoulding must adopt movable device to control.Inner bag gently pressed the movable block face to make movable block motion and effective support inner bag concave part when casing vertically was inserted in mold before the foam box, and movable block and casing are synchronized with the movement and get out of the way concave surface casing is deviate from when deviating from casing.
Fig. 1, shown in Figure 2, this movable block is the oblique sliping type lever construction in the prior art, be on the inclined-plane between main body loose tool 9 and the movable block 1, to slide by sliding assembly 2, lift 1 one-tenth demoulding state shown in Figure 2 of movable block by leverage, when the end face of light pressure movable block 1 and side, movable block 1 is with respect to main body loose tool 9 parallel motion like a cork.The existing problem of this version is, the stroke of movable block 1 need produce collision at sliding assembly 2 and limited block and just obtain restriction when contacting, can damage sliding assembly for a long time, the installed surface difficulty of processing of movable block 1 and main body loose tool 9 is big, required precision is high, the matching requirements height, gap between movable block 1 and the main body loose tool 9 will guarantee about 0.5mm, the big influence in gap is attractive in appearance, little then cause easily pull stuck causing between movable block 1 and the main body loose tool 9 can't the demoulding, cause serious product quality loss; The requirement of precision has improved die cost.
The utility model content
The utility model is for avoiding the existing weak point of above-mentioned prior art; provide a kind of simple in structure, can reduce cost; be easy to install and can guarantee and cooperate, move stable and consistent between movable block and the main body loose tool, thus guarantee casing be inserted in the main body loose tool with deviate from operation carry out foam box mould mould emptier smoothly to improve the quality of products.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model foam box mould mould emptier is to be provided with:
Be fixed on connecting rod base A, connecting rod base B on the movable block;
Be fixed on connecting rod base C, connecting rod base D on the plane casting platform;
Constitute each connecting rod of two groups of four-bar mechanisms that be arranged in parallel; Described each connecting rod is connecting rod A, connecting rod B, connecting rod C and the connecting rod D that is connected between each connecting rod base;
With hinged with rotating shaft A, rotating shaft B, rotating shaft C and rotating shaft D respectively, and between each connecting rod and rotating shaft interference fit between described each connecting rod and the connecting rod base;
Weighted lever is center of rotation with the rotating shaft C, and the weighted lever tail end is provided with balancing weight, front end and the hinged formation balanced lever of rotating shaft A mechanism.
The utility model is to be the center with rotating shaft C and rotating shaft D, with connecting rod A, connecting rod B, connecting rod C and connecting rod D is support, make the installed surface of movable block do parallel movement in a curve up and down with plane casting table top, and gently lift movable block with balanced lever mechanism and make mechanism keep demoulding state, when end face that presses movable block gently and side, movable block can be done movement in a curve like a cork up and down.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, movable block can stably with between the main body loose tool be done parallel movement in a curve in the utility model, to be face form seamless completed state between movable block and the main body loose tool with contacting of face to exercise end, and can limit that the stroke size of movable block maintains a long-term stability about parallel movement in a curve.
2, the required workpiece of the utility model is a plain steel, and simple shape is easily processed, and is with low cost, the installation casting platform on the piece that takes in sail, and the weight of reduction movable block alleviates mechanism and bears a heavy burden, and mechanism is more stably moved.

The specific embodiment
Referring to Fig. 3, Fig. 4 and Fig. 6, in the present embodiment, the connecting rod base A 13, the connecting rod base B 14 that are fixed on the movable block 1 are set; Be fixed on connecting rod base C 15, connecting rod base D 17 on the plane casting platform; Constitute each connecting rod of two groups of four-bar mechanisms that be arranged in parallel; Each connecting rod is connecting rod A 18, connecting rod B 10, connecting rod C 11 and the connecting rod D 12 that is connected between each connecting rod base; Hinged with rotating shaft A 2, rotating shaft B 3, rotating shaft C 4 and rotating shaft D 5 respectively between each connecting rod and the connecting rod base, and be interference fit between each connecting rod and rotating shaft.
Fig. 3, shown in Figure 5 is provided with balanced lever mechanism, and weighted lever 6 is a center of rotation with rotating shaft C 4, and the tail end of weighted lever 6 is provided with balancing weight 7, and front end and rotating shaft A 1 are hinged.
In concrete the enforcement, can be provided with rotating shaft C 4 and rotating shaft D 5 according to the shape concave surface degree of depth of movable block is the center, with connecting rod A 18, connecting rod B 10, connecting rod C 11 and connecting rod D 12 is support, make the installed surface of movable block 1 do parallel movement in a curve up and down with the plane of plane casting platform 8, and gently lift movable block with leverage and make mechanism remain on demoulding state shown in Figure 6, and when end face that touches the pressure movable block and side, movable block can be done movement in a curve easily up and down.
The course of work is as follows:
When the casing vertical sleeve is gone into main body loose tool 9, inner bag relative shape face presses the end face of movable block 1 earlier, movable block 1 is descended and drivening rod seat A 13, connecting rod base B 14, drive hinged rotating shaft A 2, rotating shaft B 3, connecting rod A 18, connecting rod B 10, connecting rod C 11 and connecting rod D 12, center with rotating shaft C 4 and rotating shaft D 5 is the parallel plane movement in a curve that benchmark is done downward outer direction and movable block 1 installed surface and plane casting platform 8, when movable block 1 contacted with main body loose tool 9, motion stopped; This moment, casing was inserted in main body loose tool 9 fully, and the box liner concave surface is filled by movable block 1.When casing is vertically deviate from main body loose tool 9, the side that box liner relative shape face presses movable block 1 earlier, make movable block 1 oppositely do parallel movement in a curve till movable block 1 gets out of the way the inner bag concave surface fully with above-mentioned, this moment casing fully and main body loose tool 9 disengagements, at this moment to borrow weighted lever 6 because of the gravity of balancing weight 7 be that the center is a bit larger tham under movable block 1 weight and gently lifts movable block with rotating shaft C 4 to movable block 1, to such an extent as to movable block keeps demoulding state, is inserted in to wait for next casing.
