Description
technical field:
The utility model relates to technical field of mold, particularly relates to cavity small-diameter circular grommet type seal mould.
background technology:
At present, all generally adopt the injection mo(u)lding of cavity mould for small diameter circular sealing gasket, because cavity dimension specification is all less, existing mould rubber mobility when injecting sizing material is poor, be difficult to ensure that sizing material can fully fill each die cavity in the process of flowing, product fraction defective is high, and production out can produce burr afterwards, and burr are manual is difficult to process.
utility model content:
The purpose of this utility model is exactly the deficiency existed for prior art and the cavity small-diameter circular grommet type seal mould providing a kind of and can ensure rubber mobility, make sizing material fully can fill each die cavity, improve the quality of products.
To achieve these goals, the technical solution adopted in the utility model is: cavity small-diameter circular grommet type seal mould, it includes from top to bottom interconnective cope match-plate pattern successively, lower bolster, enclose between cope match-plate pattern and lower bolster and form multiple die cavity, wherein, multiple upper cavity is offered bottom cope match-plate pattern, protrusion core rod is convexly equipped with downwards in the middle part of upper cavity, the position corresponding with each upper cavity, lower bolster top offers shrinkage pool die cavity respectively, protruding core rod stretches in shrinkage pool die cavity, corresponding upper cavity, protrude between core rod and shrinkage pool die cavity and mutually enclose the described die cavity of formation, each die cavity outer peripheral edge is formed around the die cavity torn edges groove of a week respectively, be interconnected between the torn edges groove of adjacent two die cavities.
Distance between described adjacent two die cavities is less than the external diameter of torn edges groove.
Distance 0.3 ~ 0.5mm less of the external diameter of torn edges groove between described adjacent two die cavities.
Described multiple cavity spacer becomes multiple region, and the die cavity in each region is matrix-style distribution.
Described multiple region is matrix-style distribution.
Distance in a same region between adjacent two die cavities is 5 ~ 6mm, and the minimum range between the die cavity in adjacent two regions is 20 ~ 30mm.
The utility model beneficial effect is: the cavity small-diameter circular grommet type seal mould that the utility model provides, include interconnective cope match-plate pattern successively from top to bottom, lower bolster, enclose between cope match-plate pattern and lower bolster and form multiple die cavity, wherein, multiple upper cavity is offered bottom cope match-plate pattern, protrusion core rod is convexly equipped with downwards in the middle part of upper cavity, the position corresponding with each upper cavity, lower bolster top offers shrinkage pool die cavity respectively, protruding core rod stretches in shrinkage pool die cavity, corresponding upper cavity, protrude between core rod and shrinkage pool die cavity and mutually enclose the described die cavity of formation, each die cavity outer peripheral edge is formed around the die cavity torn edges groove of a week respectively, be interconnected between the torn edges groove of adjacent two die cavities, ensure rubber mobility, make sizing material can enter each die cavity by torn edges concentrated flow, ensure that sizing material can fully fill each die cavity in the process of flowing, and torn edges groove can form torn edges in product periphery, be convenient to utilize equipment stamping-out burr removing, the appearance requirement after product Burr removal can be ensured.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Fig. 3 is the fragmentary sectional view of the utility model decomposing state.
Fig. 4 is the distribution schematic diagram of the utility model die cavity.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described, see shown in Fig. 1 ~ 4, the utility model includes from top to bottom interconnective cope match-plate pattern 1 successively, lower bolster 2, enclose between cope match-plate pattern 1 and lower bolster 2 and form multiple die cavity 3, wherein, multiple upper cavity 11 is offered bottom cope match-plate pattern 1, be convexly equipped with downwards in the middle part of upper cavity 11 and protrude core rod 12, the position corresponding with each upper cavity 11, lower bolster 2 top offers shrinkage pool die cavity 21 respectively, protruding core rod 12 stretches in shrinkage pool die cavity 21, corresponding upper cavity 11, protrude between core rod 12 and shrinkage pool die cavity 21 and mutually enclose the described die cavity 3 of formation, each die cavity 3 outer peripheral edge is formed around the die cavity torn edges groove 4 of 3 one weeks respectively, be interconnected between the torn edges groove 4 of adjacent two die cavities 3, ensure rubber mobility, make sizing material can flow into each die cavity 3 by torn edges groove 4, ensure that sizing material fully can fill each die cavity 3 in the process of flowing, and torn edges groove 4 can form torn edges in product periphery, be convenient to utilize equipment stamping-out burr removing, the appearance requirement after product Burr removal can be ensured.
Distance between adjacent two die cavities 3 is less than the external diameter of torn edges groove 4, makes to be formed between adjacent two torn edges grooves 4 to cut, thus is communicated with to get up by two torn edges grooves 4.Distance 0.3 ~ 0.5mm less of the external diameter of torn edges groove 4 between adjacent two die cavities 3.
Multiple die cavity 3 is separated into multiple region 5, the distribution in matrix-style of the die cavity 3 in each region 5, the distribution in matrix-style of multiple region 5.Distance in a same region 5 between adjacent two die cavities 3 is 5 ~ 6mm, and the minimum range between the die cavity 3 in adjacent two regions 5 is 20 ~ 30mm.The utility model divides multiple drape forming, be convenient to subregion invocation facility stamping-out burr removing when postorder is processed, improve burr removing efficiency, and the shaping die cavity 3 in each region 5 that makes in subregion is more concentrated, the pressure of each region 5 unit are can be increased, ensure the abundant flowing of material, make product burr thickness even, smooth appearance, thus improve production efficiency and product quality.
Certainly, the above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
