The utility model discloses an advantage: the arc convex surface of the laminating die cavity that the glued membrane can be better during vacuum plastic molding improves the shaping quality of product, during the drawing of patterns product can be smoothly the drawing of patterns from the die cavity in, simple structure, the drawing of patterns are efficient.
Description
Technical field
The utility model relates to a kind of plastics suction mould, is specifically related to a kind of high laminating degree and is easy to the plastics suction mould of the demoulding.
Background technology
Plastic uptake is that adopt vacuum suction glued membrane to be stretching in the surface of mould, cooling forming obtains product, is widely used in the industries such as plastics package, lamp decoration, advertisement and decoration by after open and flat glued membrane heating deliquescing.
Existing a lot of plastic uptake product, need at its edge formation fillet structure, in plastics suction mould drawing process, die joint is arranged on above the die cavity of die ontology, the edge of glued membrane is fixed on die joint, carry out glued membrane when plastic uptake is shaped by vacuum sucking holes to be stretched, in drawing process, the amount of tension of glued membrane is large, glued membrane outside arc convex is subject to self tensile force, and this glued membrane tensile force is directly corresponding on the arc-shaped concave of final required product, glued membrane is made better not to be attached on arc convex, the product arc-shaped concave produced is caused to be stretched distortion, be difficult to the form accuracy ensureing product, product can not be fitted with other products causes product bad, waste production cost, defect is obvious.
Because glued membrane is by being adsorbed on mould after heating, through often there is the situation that product is difficult to the demoulding after formed product, routine techniques adopts the form such as pre-coating release agent or lubricant, to prevent sticking to mould situation and to realize the smooth demoulding of product, but releasing agents etc. need all to want precoating, and are easy to polluted product and environment at every turn.
Utility model content
The utility model proposes high laminating degree and be easy to the plastics suction mould of the demoulding, its object is intended to overcome prior art above shortcomings, improve the laminating degree of product and mold cavity in plastic uptake process, realize plastic uptake product the smooth demoulding and without the need to using releasing agent etc.
Technical solution of the present utility model: high laminating degree and be easy to the plastics suction mould of the demoulding, its structure comprises die ontology, this die ontology is established the vacuum sucking holes of die cavity and corresponding die cavity; Die cavity has arc convex; Elastic mechanism is established at the edge of die cavity, this elastic mechanism comprise be arranged on die cavity edge support column, A spring is on the support columns installed and is arranged on the fixture of A spring one end, the height of this fixture is lower than the detecting parting surface height of die cavity; Die ontology there is the mould emptier being positioned at die cavity gap; this mould emptier comprises the guide pillar be arranged in the groove of die ontology; on this guide pillar, cover has demoulding block and B spring; this B spring is between the bottom of groove and demoulding block; groove is consistent with the area of section of demoulding block; guide pillar is also provided with limited block, and when the upper surface of demoulding block is concordant with the upper surface of die ontology, the upper surface of limited block contacts with the lower surface of demoulding block.
Preferably, the upper surface of described support column is lower than the upper surface of die ontology.
Preferably, during plastics sucking moulding, the upper surface of described demoulding block is concordant with the upper surface of die ontology.
Preferably, during the demoulding, the upper surface of described demoulding block protrudes from the upper surface of die ontology.
Advantage of the present utility model: during vacuum forming, glued membrane can better be fitted the arc convex of die cavity, improves the shaping quality of product; During the demoulding, product can smoothly from the demoulding in die cavity, and structure is simple, demoulding efficiency is high.
Accompanying drawing explanation
Fig. 1 be high laminating degree and the plastics suction mould being easy to the demoulding for structural representation during glued membrane plastics sucking moulding.
Fig. 2 is A portion structure for amplifying schematic diagram in Fig. 1.
In figure 1 is die ontology, 2 are die cavities, 3 are arc convex, 4 are vacuum sucking holes, 5 are glued membranes, 6 are fixtures, 7 are A springs, 8 are support columns, 9 are demoulding blocks, 10 are guide pillars, 11 are B springs, 12 are grooves, 13 is limited blocks.
Detailed description of the invention
Below in conjunction with embodiment and detailed description of the invention, the utility model is described in further detail.
As shown in Figure 1, 2, high laminating degree and be easy to the plastics suction mould of the demoulding, its structure comprises die ontology 1, this die ontology 1 is established the vacuum sucking holes 4 of die cavity 2 and corresponding die cavity 2; Die cavity 2 has arc convex 3, for the arc-shaped concave of formed product; Elastic mechanism is established at the edge of die cavity 2, for the edge of fixing glued membrane 5, this elastic mechanism comprise be arranged on die cavity 2 edge support column 8, be arranged on the A spring 7 on support column 8 and be arranged on the fixture 6 of A spring 7 one end, the height of this fixture 6 is lower than the detecting parting surface height of die cavity 2, with the die joint making glued membrane 5 be close to die cavity 2, guarantee vacuum during plastic uptake; Die ontology 1 is also provided with the mould emptier being positioned at die cavity 2 gap; this mould emptier comprises the guide pillar 10 be arranged in the groove 12 of die ontology 1; on this guide pillar 10, cover has demoulding block 9 and B spring 11; this B spring 11 is between the bottom of groove 12 and demoulding block 9; groove 12 is consistent with the area of section of demoulding block 9; guide pillar 10 is also provided with limited block 13, and when the upper surface of demoulding block 9 is concordant with the upper surface of die ontology 1, the upper surface of limited block 13 contacts with the lower surface of demoulding block 9.
The upper surface of described support column 8 is lower than the upper surface of die ontology 1.
During plastics sucking moulding, the upper surface of demoulding block 9 is concordant with the upper surface of die ontology 1.
During the demoulding, the upper surface of demoulding block 9 protrudes from the upper surface of die ontology 1.
According to above structure, when plastics sucking moulding, when vacuum acquires a certain degree, the deformational stress of glued membrane 5 is greater than the elastic force of A spring 7, thus A spring 7 is stretched, glued membrane 5 has moving inward to a certain degree, thus glued membrane 5 better laminating die cavity 2 arc convex 3 when guaranteeing vacuum forming, and glued membrane 5 pairs of demoulding blocks 9 are exerted pressure and then to compress B spring 11 to demoulding block 9 upper surface concordant with die ontology 1 upper surface to complete plastics sucking moulding; During the demoulding, the external force be applied on demoulding block 9 reduces, and the elastic force of B spring 11 makes demoulding block 9 rise to protrude the upper surface of die ontology 1, and then makes product smoothly from the demoulding in die cavity 2 by the effect of demoulding block 9.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
