Utility model content
The utility model provides a kind of upper cover of connecting box mould, and described mould comprises: top board; Upper thermal insulation board, described upper thermal insulation board is located on the lower surface of described top board; Cope match plate, described cope match plate is located on the lower surface of described upper thermal insulation board; Lower template, described lower template is located on the lower surface of described cope match plate, between wherein said cope match plate and described lower template, limits die cavity; Lower thermal insulation board, described lower thermal insulation board is located on the lower surface of described lower template; Base plate, described base plate is located on the lower surface of described lower thermal insulation board; Back stitching, is the push rod arranging in order to allow when the mould matched moulds front mould top return back to top needle plate, and described back stitching is located at the lower surface of thermal insulation board, and back stitching has been appended air discharge duct.
Preferably, multiple back stitchings are symmetrically located at the lower surface of thermal insulation board.
Preferably, 4 back stitchings are symmetrically located at the lower surface of thermal insulation board.
Preferably, described back stitching is mobilizable in upper thermal insulation board, on the track that upper thermal insulation board inside moves up and down in back stitching, is provided with groove.
Preferably, described 4 back stitchings are respectively appended an air discharge duct.
Preferably, described air discharge duct one end is communicated with the groove of upper thermal insulation board inside, and one end penetrates the side of thermal insulation board, directly ingress of air.
Preferably, described top board, described upper thermal insulation board, described cope match plate, described lower template, described lower thermal insulation board and described base plate removably link together by bolt.
Preferably, described top board, described upper thermal insulation board, described cope match plate, described lower template, described lower thermal insulation board and described base plate removably link together by multiple described bolts.
Preferably, multiple described bolts are positioned on the first circumference.
Preferably, multiple described bolts are distributed on described the first circumference equally spacedly.
In original upper cover of connecting box Design of Dies, back stitching part is often bad because of resistance problem return, and because matched moulds is too fast, causes the moment cannot be air scavenge, the clamp force of final mould is excessive, the utility model appends exhaust on each back stitching, and exhaust well while making closure pressing speed very fast adopts after design of the present utility model, mould back stitching can not cause return bad because of tired gas, guarantee that each matched moulds is effective, and enhance productivity, reduce costs.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present utility model and advantage accompanying drawing below combination is understood becoming the description of embodiment obviously and easily, wherein:
Fig. 1 is according to the structural representation of the mould of the utility model embodiment.
In figure: 1, mould; 10, upper thermal insulation board; 20, back stitching; 30, air discharge duct.
The specific embodiment
Describe embodiment of the present utility model below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Below with reference to Fig. 1, describe according to the mould 1 of the utility model embodiment.As shown in Figure 1, according to the mould 1 of the utility model embodiment, comprise top board, upper thermal insulation board 10, cope match plate, lower template, lower thermal insulation board, base plate and back stitching 20.
Upper thermal insulation board 10 is located on the lower surface of top board, and cope match plate is located on the lower surface of thermal insulation board 10.Lower template is located on the lower surface of cope match plate, wherein between cope match plate and lower template, limits the die cavity being communicated with hot flow path.Lower thermal insulation board is located on the lower surface of lower template, and base plate is located on the lower surface of lower thermal insulation board.Back stitching 20 is located at the lower surface of thermal insulation board 10, is the push rod arranging in order to allow when mould 1 matched moulds front mould top return back to top needle plate.
Preferably, 4 back stitchings 20 are symmetrically located at the lower surface of thermal insulation board 10, back stitching 20 is mobilizable in upper thermal insulation board 10, on the track that upper thermal insulation board 10 inside move up and down in back stitching 20, be provided with groove, when practical operation, back stitching 20 parts are often because resistance problem return is bad, and because matched moulds is too fast, cause the moment cannot be air scavenge, the clamp force of final mould 1 is excessive, for addressing this problem, 4 back stitchings 20 are respectively appended an air discharge duct 30, air discharge duct 30 one end are communicated with the groove of upper thermal insulation board 10 inside, one end penetrates the side of thermal insulation board 10, directly ingress of air, the utility model appends exhaust on each back stitching 20, exhaust well while making closure pressing speed very fast, adopt after design of the present utility model, mould 1 back stitching can not cause return bad because of tired gas, guarantee that each matched moulds is effective, and enhance productivity, reduce costs.
