Description
[technical field]
The present invention relates to a kind of slide block structure, particularly relate to a kind of antiseized slide block structure of mould.
[background technology]
In the time adopting mould to carry out production, often can use slide block structure and carry out the moulding of product, but slide block is in the time exiting, and can mutually stick together with product again, causes the two to separate.
Refer to Fig. 1, it illustrates the antiseized slide block structure into a kind of mould of prior art.This sliding block anti-adhesion structure applications is in having the product 10 in breaking hole 11 and separating of slide block 12, and this structure comprises: spring 13, be located in described slide block 12; False thimble 14, its one end is in spring 14 described in matched moulds state lower compression, and the other end is held in the breaking hole 11 of product 10.
In the time of die sinking, described slide block 12 moves, and described in two, false thimble 14 supports described product 10 by described breaking hole 11, and described slide block 12 separates with described product 10, and after described spring 14 discharges completely, described false thimble 14 also departs from described breaking hole 11.But the structure shown in Fig. 1 can only be applicable to possess the product 10 in breaking hole 11 and separating of slide block 12.
Referring again to Fig. 2, it illustrates the antiseized slide block structure into the another kind of mould of prior art.This sliding block anti-adhesion structure applications is in having separating of product 20 that large area position can support and slide block 21, and this structure comprises: slide block bundle piece 22, and it has vertical plane 23 and the inclined plane 24 to downward-extension by this vertical plane 23; Spring 25, is located in described slide block 21 away from described product 20 1 sides; False thimble 26, it is arranged in described slide block 21, on this vacation thimble 26, there is a stop block 27, described stop block 27 is located at described spring away from described product 20 one end, in the time of matched moulds, described false thimble 26 one end are held in described product 20, and the other end is held in the vertical plane 23 of described slide block bundle piece 22.
In the time of die sinking, described slide block bundle piece 22 moves upward, described slide block 21 moves in the horizontal direction, described false thimble 26 one end are held in described product 20, thereby make described product 20 depart from easily described slide block 12, and described false thimble 26 other ends are held in the vertical plane 23 of described slide block bundle piece 22, so described false thimble 26 does not move, in the time that described slide block bundle piece 22 moves up to described inclined plane 24 and contacts with described false thimble 26, described spring 25 discharges, the stopper section 27 of described false thimble 26 is driven, and described false thimble 26 one end depart from described product 20.
But the structure shown in Fig. 2 can only be applicable to possess separating of product 20 that large area position can support and slide block 21.
Refer to Fig. 3, the structural representation that Fig. 3 is a kind of product.Described product 30 1 sides are provided with three extensions 31, and each described extension 31 areas are less, on each described extension 31, are all provided with hole post 31, the post 31 neither breakings of each described hole.
Visible, described product 30, because the position that needs moulding does not exist breaking hole, therefore can not adopt the antiseized slide block structure of mould as shown in Figure 1; Meanwhile, because the area of the described extension 31 of described product 30 is less, the therefore also antiseized slide block structure of inapplicable mould as described in Figure 2.
In view of this, be necessary to develop in fact a kind of antiseized slide block structure of mould, to address the above problem.
