Abstract
The utility model discloses a heat sealing welding die which includes a die matrix with a working face; the working face is coated with an elastic cushion used to support welding work piece; the elastic cushion is provided with a bearing face which can be fully adhered to the welding zone of the welding work piece and a distorted face which can fully match with the working face by being pressed and deformed. The heat sealing welding die manufactured by the technical proposal makes up for the deficiency of the uneven working face of the die matrix by the elastic cushion; the bearing face of the elastic cushion is used as the actual working face of the heat sealing welding die, is fully adhered to and matches with the welding zone of the welding work piece, so that the pressure is distributed evenly during welding, so as to eliminate the appearance deficiencies, such as weak welding, faulted welding, welding position displacement, uneven welding depth, etc. and performance deficiencies, such as labor waste in film uncovering, etc., and ensure welding sealing performance. Plenty of production practices prove that the welding conformity rate of the heat sealing welding die reaches above 99.82 percent.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of heat-sealing weld mold of workpiece being realized seal welding by the heating pressurization.
Background technology
For using the envelope film that the place of plastic opening is sealed, use welding robot usually, weld mold will seal film under the condition of heating pressurization and plastic fuses together, instant heating soldering and sealing connects.As shown in Figure 1, during the heat-sealing welding, weld mold 1 ' working face 2 ' tend to former thereby produce some rough defectives because of the difficulty of processing and fabricating or technology do not reach designing requirement etc., cause working face 2 ' and welding work pieces 3 ' between can not fit like a glove, exist gap 4 ', pressure distribution is inhomogeneous during welding work pieces 3 ' pressurized.Seal welding in the case and can produce a series of defective: open defects such as for example button thes be white, rosin joint, welding position skew, the depth of weld are inhomogeneous, and can have influence on the performance of product, when product uses, need and to seal the occasion that film is taken off, then cause taking off the film effort, another serious situation is to reveal because of sealing the article that not exclusively make in the airtight container.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weld defect, provides a kind of welding effect good heat-sealing weld mold.
For achieving the above object, the utility model has adopted following technical scheme: a kind of heat-sealing weld mold is provided, comprises the die matrix with working face, be coated with the cushion that is used to support welding work pieces on the described working face; The deformation plance that described cushion has the bearing-surface that can be close to fully with the welding region of described welding work pieces and can fit like a glove by compressive deformation and the formation of described working face.
Described cushion is preferably the solid rubber pad.
Described bearing-surface can adopt suitable with it plane or cambered surface according to the shape of the welding region of welding work pieces.
Described cushion can be laid on the described die matrix.
The heat-sealing weld mold that adopts technique scheme to make, because of having filled up the rough defective of die matrix working face by cushion, the bearing-surface of this cushion is as the working face of this heat-sealing weld mold reality and the complete snug fit of welding region of welding work pieces, pressure distribution is even when making welding, open defect such as eliminated that button is white, rosin joint, welding position skew, the depth of weld are inhomogeneous and take off defective on the performance such as film effort, welded seal is good.By a large amount of production practices, prove that the solder yield of this heat-sealing weld mold reaches more than 99.82%.
Description of drawings
Fig. 1 is existing a kind of structural representation that seals weld mold;
Fig. 2 is the structural representation of a kind of preferred embodiment of the utility model heat-sealing weld mold;
Fig. 3 is an operation principle schematic diagram embodiment illustrated in fig. 1.
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in further detail.
The specific embodiment
Referring to Fig. 2, a kind of preferred embodiment of the utility model heat-sealing weld mold comprises die matrix 1, directly be equipped with the solid rubber cushion 3 that is used to support welding work pieces 5 on the working face 2 of this die matrix 1, have rough gap 6 between the working face 2 of die matrix 1 and the welding work pieces 5; This solid rubber cushion 3 has the bearing-surface 4 that can be close to fully with the welding region of welding work pieces 5 and the deformation plance 7 relative with working face 2, and this bearing-surface 4 can adopt suitable with it plane or cambered surface according to the shape of the welding region of welding work pieces 5.
Referring to Fig. 3, along under the effect of solder side well-distributed pressure F (N), the deformation plance 7 of solid rubber cushion 3 fits like a glove by working face 2 formation of distortion with die matrix 1, make solid rubber cushion 3 fill rough gap 6 between working face 2 shown in Fig. 2 and the welding work pieces 5, the bearing-surface 4 of solid rubber cushion 3 has replaced the working face 2 of die matrix 1, becomes actual welding job face.When welding, can guarantee that the pressure distribution of welding work pieces 5 is even, open defect such as eliminated that button is white, rosin joint, welding position skew, the depth of weld are inhomogeneous and take off defective on the performance such as film effort, welded seal is good.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the present utility model design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.For example, except elastomeric material, can also adopt other elastomeric materials such as foam to make cushion of the present utility model; The mode of this cushion except laying can also utilize mode such as bonding to be fixed on the working face of die matrix.
