Abstract
The utility model provides a die exhausting structure. The die exhausting structure is mounted in a die core and comprises a base and breathable steel which is adhered to the surface of the base and covers the surface of the base; a groove is formed in the surface, in contact with the breathable steel, on the base; a cooling water channel and a suction and exhausting pipeline communicated with the groove are arranged inside the base. According to the die exhausting structure provided by the utility model, exhausting limitation of an existing exhausting mold insert is broken up, the problem of a weld line of a product is solved, and the yield of products is improved.
Description
Technical field
The utility model relates to a kind of die venting structure.
Background technology
For the higher product of appearance requirement, as phone housing, because there is air in mold cavity, need to make exhaust mold insert mould is carried out to exhaust, existing exhaust mold insert is single gas form, and exhaust is insufficient, easily cause residual air in die cavity, produce weld bond, affect product appearance.
Summary of the invention
For overcoming the problem of the deficiencies in the prior art and existence, the utility model provides a kind of effective die venting structure that improves product weld bond problem, improves product yield.
The utility model is achieved through the following technical solutions:
, being installed in die, described exhaust structure comprises that pedestal and laminating are covered in the ventilative steel on base-plates surface; The surface contacting with ventilative steel on described pedestal offers groove, the suction and discharge pipeline that base interior is provided with cooling water channel and communicates with groove.
Described groove is snakelike or S shape.
The surperficial surrounding contacting with ventilative steel on described pedestal is provided with buckling groove, and ventilative steel is provided with the projection with the clamping of buckling groove phase.
The wedging position of described exhaust structure is provided with screw, and it is inner that described screw extends to ventilative steel from base bottom surface, by screw, locked.
In exhaust structure installation described in the utility model and die, ventilative steel both, as the mold insert of plastic parts moulding, can be discharged type intracavity gas again simultaneously; The surface contacting with ventilative steel on pedestal offers snakelike or S connected in star, and groove communicates with suction and discharge pipeline, before injection moulding, by suction and discharge pipeline, takes air in die cavity away, makes that die cavity is capable becomes negative pressure state, avoids product formation weld bond; Injection moulding completes after ejecting product, by suction and discharge pipeline, blows, and the impurity in ventilative steel gap is blown away, and enters the next suction and discharge cycle; Snakelike or S connected in star has increased the breathing area of ventilative steel, type cavity gas is discharged more rapid, and product ejects the rear more convenient impurity in ventilative steel that blows out.
Accompanying drawing explanation
Fig. 1 is the utility model base construction schematic diagram;
Fig. 2 is the utility model overall structure schematic diagram.
In figure: 1-pedestal, the 2-steel of breathing freely, 3-suction and discharge pipeline, 4-cooling water channel, 5-groove, 6-buckling groove, 7-projection, 8-screw.
The specific embodiment
Understanding for the ease of those skilled in the art, is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of die venting structure, inlays and is installed in die, and described exhaust structure comprises that pedestal 1 and laminating are covered in the lip-deep ventilative steel 2 of pedestal 1, and ventilative steel 2 surfaces are concordant with die cavity; The surface contacting with ventilative steel 2 on described pedestal 1 offers groove 5, the suction and discharge pipeline 3 that pedestal 1 inside is provided with cooling water channel 4 and communicates with groove 5.Before injection moulding, by suction and discharge pipeline 3, take air in die cavity away, make die cavity form negative pressure state, avoid product formation weld bond; Injection moulding completes after ejecting product, by suction and discharge pipeline 3, blows, and the impurity in ventilative steel 2 gaps is blown away, and enters the next suction and discharge cycle.Described groove 5 is snakelike or S shape, and groove 5 snakelike or S shape has increased the breathing area of ventilative steel 2, type cavity gas is discharged more rapid, and product ejects the rear more convenient impurity in ventilative steel that blows out.
The surperficial surrounding contacting with ventilative steel 2 on described pedestal 1 is provided with buckling groove 6, and ventilative steel 2 is provided with the projection 7 with buckling groove 6 phase clampings, and buckling groove 6 and projection 7 coordinate location, guarantee accuracy.
The wedging position of described exhaust structure is provided with screw 8, and described screw 8 extends to ventilative steel 2 inside from pedestal 1 bottom surface, by screw, locked.
The content of mentioning in above-described embodiment is not to restriction of the present utility model, is not departing under the prerequisite of inventive concept of the present utility model, and any apparent replacement is all within protection domain of the present utility model.
