In figure: 1 top die, 2 counterdies, 3 die heads, 4 die cavitys, 5 locating dowels, 6 positioning baffles.

The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of stock mould, comprises top die 1 and counterdie 2.Wherein, be distributed with a plurality of die heads 3 on the stamping surface of top die 1, counterdie 2 is provided with a plurality of die cavitys 4 that coordinate with die head 3, and this die cavity 4 can adopt rectangle frame posture structure (comprising the four edges frame) and by the polylith dividing plate, counterdie 2 is separated into a plurality of die cavitys 4.Wherein, die head 3 also can be formed side by side by the die head of many groups less, and die head 3 can be plugged in die cavity 4.Wherein, in the present embodiment, the structure of top die 1 and counterdie 2 is identical with the structure of existing stock mould, and certainly the stock mould in the utility model can also comprise other structures, as die holder, extruding cylinder etc., for common practise the present embodiment of this area describes in detail no longer one by one.

Wherein, referring to Fig. 1-3, improvements of the present utility model are: be provided with location structure between top die 1 and counterdie 2, particularly, top die 1 is provided with location structure (comprising locating dowel 5 in Fig. 1 and the positioning baffle 6 in Fig. 2), when making matched moulds press brick, die head 3 base plane are parallel to die cavity 4 base plane and die head 3 bottoms and are positioned at approximately 1-3mm of die cavity 4 belows, bottoms.When namely guaranteeing matched moulds, die head 3 bottoms are concordant with die cavity 4 bottoms but slightly pass die cavity 4 bottoms, and within the distance that passes will be strict controlled in 1-3mm, and concrete numerical value can be determined according to the precision of batching, moisture and the brick machine of brick etc.The improvement principle is: when the outstanding die cavity 4 of die head 3 guarantees matched moulds, material does not enter in die cavity 4, guarantee stripping result, and die head can be with the brick pressure break when controlling outstanding distance and closing film for the 1-3mm assurance, only have the distance of to give prominence to be controlled within 1-3mm and could effectively guarantee stripping result, make the success rate of last brickmaking reach 99%, especially be fit to and light-weight brick.

Particularly, the location structure in the utility model embodiment can be the common location structures such as locating dowel, locator protrusions or positioning baffle, and the below describes with locating dowel and positioning baffle respectively:

Wherein, referring to Fig. 1, location structure in the utility model embodiment is on four angles of 5, four locating dowels 5 of four identical locating dowels stamping surface of being fixed on vertically downward respectively top die 1, and during matched moulds, locating dowel 5 lower ends contact with the upper surface of counterdie 2 frames and are used for supporting top die 1.Wherein, according to the mould of different size, the height of locating dowel 5 can be the height of 0.6-0.8 times of die cavity 4.

Wherein, referring to Fig. 2, location structure in the utility model embodiment is two positioning baffles 6, this positioning baffle 6 is parallel to die cavity 4 bottoms settings, and be fixed on a pair of side of die head 3 sides, all around, die cavity 4 is given prominence at the two ends of positioning baffle 6, and during matched moulds, the two ends of positioning baffle 6 rest and are used for supporting top die 1 on counterdie 2 frames.Particularly, as shown in Figure 2, the front and back sides that two positioning baffles 6 are fixed on to horizontal symmetrical respectively top die 1 effluxes the outside of die head 3 most, and the length of positioning baffle is greater than the length (same direction) of die cavity.

Concrete use procedure is: upper press mold 1 promotes, counterdie 2 descends, distribution device begins cloth in the die cavity 4, after cloth was completed, top die 1 was inserted into accordingly and begins to carry out the compacting of brick body in die cavity 4, completes matched moulds when the backstay on top die 1 touches counterdie 2 frame, when arriving the set-point, the pressure brick is complete, prepares the demoulding, brickmaking success after the demoulding is completed.

The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
