Abstract
The utility model discloses a reserve forming die of hole when the product is fashioned. The technical scheme is as follows: the utility model provides a SMC product back-off forming die, includes mould, lower mould and drawing of patterns thimble, goes up mould and lower mould and places from top to bottom, thimble one end and product contact, drawing of patterns thimble upper end is equipped with inserts, inserts and inlays in the lower mould, during the shaping with the product contact, the auxiliary forming, one side of inserting is equipped with the arch, can the shaping hole. The movable insert helps to form the hole opening part, the movable insert is taken out along with the product during die opening, and the insert can be taken down to complete forming without damaging the product structure.
Description
Technical field
This utility model belongs to SMC product forming mould field, particularly relates to a kind of back-off mould.
Background technology
The prepreg of a kind of dry tablet shape that sheet molding compound (abbreviation SMC) is made up of unsaturated polyester resin, low shrinkage additive, filler, firming agent, thickening agent, releasing agent and glass fibre etc., it has the features such as shrinkage factor is low, intensity is high, convenient formation, is particularly suitable for industrialization large-scale production. It is frequently necessary to more reserved holes at the edge of product and interface section and facilitate later stage bolt anchoring or secondary operations, the mode generally adopted is after product main body molding, hole again, produce in the face of large-scale, need great labor cost, simultaneously because later stage Manual punching, the position of hole has trickle deviation, reduces the precision of product.
Utility model content
For the problems referred to above, the purpose of this utility model is in that to provide a kind of mould having reserved hole while formed product. The technical scheme is that a kind of SMC product back-off mould, including upper die and lower die and demoulding thimble, upper die and lower die are placed up and down, thimble one end contacts with product, and described demoulding thimble upper end is provided with insert, and insert is embedded in counterdie, contact with product during molding, assistant formation, the side of described insert is provided with projection, it is possible to molding hole. The main part of upper die and lower die shaped article, loose plug helps molding aperture segment, and during die sinking, loose plug is carried over together along with product, takes off insert and plastic completes, not damaging product configurations.
Further, the draw-in groove location passing through between described insert and demoulding thimble to match is placed. Can being mutually disengaged between insert and demoulding thimble, draw-in groove Position Design is not shifted over when can guarantee that work, and whether convenient confirmation mould installation puts in place.
Further, described demoulding thimble is inside counterdie, corresponding with the position of described insert. Demoulding thimble is inside counterdie, it is not necessary to additional designs support, it is ensured that thimble position is accurate.
Adopt the technical solution of the utility model to have the advantages that additionally do not increasing on the basis of multi-mould and operating procedure, solve the problem that molding operates respectively with perforate two procedures, drastically increase production efficiency; Opening step mould location replaces manual operation simultaneously, and position of opening is more accurate, improves the precision of product, improves the quality of product.

Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by this utility model; without the conversion that creative work obtains, all should be encompassed in this utility model protection domain.
As it can be seen, SMC product 5 is needing fixing position to arrange protruding sheet material 1, it is necessary in the boring hole, position 2 of sheet material 1, upper die and lower die about 3 are placed, demoulding thimble 7 upper end is provided with insert 4, and counterdie 7, in the hole needing the position of insert 4 to be provided with through, is used for placing demoulding thimble 7. Described demoulding thimble 7 is fixed in frame 8, it is possible to produce relative sliding with counterdie 3 under the drive of cylinder.
Demoulding thimble 7 other end contacts with insert 4, and contact surface is the arc 6 mated each other, it is simple to insert 4 is in place. Insert 4 is provided with projection, and for molding hole 2, the form fit counterdie 3 of insert 4 is for shaped article 5.
During product 5 demoulding, after upper die and lower die 3 die sinking, demoulding thimble 7 upwards jack-up, now insert 4 is additionally attached on product 5, after product stripping success, insert 4 is taken off, namely product has produced, and by product 5 back-off one-shot forming, greatly reduces process time and cost.
