The invention provides an airbag plastic mould in which junctures of a lifter and a product as well as a moving core are less prone to generation of flash and the product is less prone to falling when ejected out. The airbag plastic mould comprises a fixed core (1), the moving core (2) and a product cavity (3) positioned between the fixed core and the moving core, the lifter (4), a right slider (6) and a left slider (7) are connected onto the product cavity (3) respectively, the lifter (4) is in sliding sleeved fit with the moving core (2), and one side of the upper end of the lifter (4) is directly connected with the product cavity (3) while the other side of the same is attached to the moving core (2). The airbag plastic mould is characterized in that a reverse button (9) is arranged on one side, attached to the moving core (2), of the lifter (4), a button buttoned with the reverse button (9) is arranged on the moving core (2), an anti-falling needle (5) is further connected onto the product cavity (3), and saw teeth (10) are arranged at a contacting position of the side face of the anti-falling needle (5) and the product cavity (3).
Description
Technical field
The present invention relates to a kind of Airbag plastic mould.
Background technology
In prior art, Airbag plastic mould comprises the indispensable part such as fixed mold core, mavable module core, oblique top and slide block.And due to the complex structure of air bag product, to the reliability of oblique top and slide block and designing requirement higher.What adopt for the ramp-roof structure of air bag in prior art is those skilled in the art the most frequently used structure, and the brace primarily of a smooth in appearance is made.When this structure is in for Airbag plastic mould, oblique top generally will design larger, and the side of oblique top is product, and opposite side is mavable module core.After formed product, product is upwards ejected mavable module core by oblique top, and take away after shaped article by workman or automatic material taking mechanism from oblique top, oblique top return back in mavable module core again, prepares to produce next product.Because oblique top shaft is larger, gap is produced between the hole wall of the oblique top jack in back off procedure easily and on mavable module core, this gap makes oblique top when formed product, the common intersection of mavable module core and product three easily occurs overlap, has influence on the use of product.Be exactly that oblique top is subject to the restriction of structure often can only withstand on the side of product in addition, when product is by lifter ejection mavable module core, product is easy to drop from oblique top rollover due to the effect of inertia force, is not easy to automatic material taking mechanism and carries out feeding operation.In sum, there is the weak point that junction easily produces overlap, product easily falls when being ejected of oblique top and product and mavable module core in Airbag plastic mould of the prior art.
Summary of the invention
The technical problem to be solved in the present invention is, provide the junction of a kind of oblique top and product and mavable module core to be not easy to produce overlap and product is ejected time be not easy the Airbag plastic mould fallen.
For solving the problems of the technologies described above, technical scheme provided by the invention is: a kind of Airbag plastic mould, and it comprises fixed mold core, mavable module core and is positioned at product die cavity between the two; Product die cavity is connected to oblique top, right slide block and left slider; With mavable module core slip fit while of oblique top, the side, upper end of oblique top directly connects with product die cavity, and opposite side and mavable module core are affixed; The side that the upper end of described oblique top and mavable module core are affixed is provided with back-off, and mavable module core is provided with the button bit interlocked with back-off; Described product die cavity is also connected with anti-fall pin, and the side of anti-fall pin and the contact position of product die cavity are provided with sawtooth.
After adopting above structure, tool of the present invention has the following advantages: the side that the upper end of described oblique top and mavable module core are affixed is provided with back-off, and mavable module core is provided with the button bit interlocked with back-off.When oblique top complete a product eject work after carry out rollback time, back-off structure is directly fastened on button bit place, can fit with mavable module core more closely in the side that the upper end of such oblique top and mavable module core are affixed, gap is between the two reduced, because gap is transferred to that side that oblique top upper end connects with product die cavity, and the side connected with product die cavity is participated in directly moulding when shaping, small gap can not have influence on the quality of product.But due to the side gap shrinks that upper end and the mavable module core of oblique top are affixed, in formed product process, plastics are difficult to enter in gap, so can not produce overlap at this place from the junction of oblique top, product and mavable module core three.In addition due to product die cavity being also connected with anti-fall pin, the contact position of anti-fall pin and product die cavity is provided with sawtooth.When completing shaping rear oblique top and product being ejected from mavable module core, anti-fall pin is also connected on product, define second supporting construction except oblique top, and be provided with sawtooth due to the contact position of anti-fall pin and product die cavity, the outside of product broached-tooth design when shaping is filled up shaping by plastics thus forms buckle type structure with the sawtooth on anti-fall pin, product can not fall easily, is conducive to follow-up automatic material taking mechanism and carries out feeding operation.
As improvement, described right slide block is secondary slide block structure, it comprises first order slide block and second level slide block, first order slide block is the slide block of horizontal slip, second level slide block is oblique slide block, first order slide block is connected with second level slide block by feather key, and second level slide block connects with the inclined open on product die cavity, second level slide block can be driven to skid off from inclined open when first order slide block level moves right.The inclined open that said structure solves on product die cavity is large by single slide block demoulding slip angle; the problem of demoulding difficulty; by secondary slide block structure, the stripping means of original direct oblique downward 36 degree is converted to by the naturally oblique slide downward of first order slide block horizontal movement drive second level slide block; do not need other oblique demolding structures such as the line position of design band separate power in addition; saved production cost, stripping operation is also more prone to.
As preferably, described back-off is 15 ~ 30mm to the distance of the junction of oblique top, product and mavable module core three.This distance range can ensure the laminating of oblique top and mavable module core to greatest extent, prevents the generation of overlap when not affecting formed product to greatest extent.
As preferably, described feather key is T-shaped.T-type structure stable connection, structure is simple, and sliding is good.
