Detailed description of the invention
With specific embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
As shown in Fig. 1,2,3,4,5, specific embodiment described in the utility model is the moulding machine at a kind of dead angle without back-up sand, including frame 1, slide bar 2, drag box 3, raising middle flask 4, cope 5, lower platen 6, top board 7, squeezing cylinder 8, upper cylinder pressure 9, blasting unit 10, mould 11, control module, described frame 1 side is vertically installed with parallel four group slide bar 2, and slide bar 2 is disposed with cope 5, drag box 3 from top to bottom；Top box movement cylinders 14 it is provided with between cope 5 and slide bar 2；Nowel movement cylinders 12 it is provided with between drag box 3 and slide bar 2；Lower platen 6 it is additionally provided with below drag box 3；Lower platen 6 is connected to squeezing cylinder 8, and cope 5 is provided above top board 7, and top board 7 is connected to cylinder pressure 9, and described raising middle flask 4 is arranged in the middle part of slide bar 2, and mould 11 is fixed in raising middle flask 4 by hook；
Squeezing cylinder 8, upper cylinder pressure 9, top box movement cylinders 14, nowel movement cylinders 12 electrically connect with control module respectively；
Slide bar 2 outside vertical orientation is each provided with a blasting unit 10 the most respectively, the porch of blasting unit 10 is provided with flashboard 21, blasting unit 10 is also connected with air pump, the sand jet outlet 16 for sand grains ejection it is provided with below blasting unit 10, being provided with Sand jet valve 15 on sand jet outlet 16, the sand jet outlet 16 of two blasting units 10 is all corresponding with the side of cope 5 and drag box 3 to be connected；The perpendicular angle of sand grains injection direction in the sand jet outlet 16 of both sides；Vertical injection can effectively reduce the dead angle penetrating sand, is suitable for the mould of various structures, it is possible to ensures the uniformity of sand mold, reduces husky hole, improves yields；
In the specific implementation, operation is sent in order to realize raising middle flask and automatically pushing of mould, slide bar side has been horizontally disposed with raising middle flask push rod 18, raising middle flask push rod guide rail and raising middle flask and has pushed away mould cylinder 17, raising middle flask push rod 18 is arranged on raising middle flask and pushes away mould cylinder 17 front end, raising middle flask push rod guide rail is arranged on below raising middle flask push rod 18, and raising middle flask push rod 18 moves along raising middle flask push rod guide rail.The appointment position that raising middle flask can be delivered between cope and drag box by operation is worked in coordination with by raising middle flask push rod and raising middle flask push rod guide rail.
In the specific implementation, in order to improve the uniformity penetrating sand further, arranging a plurality of sand jet outlet 16 bottom blasting unit 10, sand jet outlet 16 front end is additionally provided with the guide plate 22 of angle adjustable.Owing to existing moulding machine is when pressing mold, can suppress multiple mould (as shown in Figure 4), single sand jet outlet structure can not meet sandblasting without dead angle, the uniform requirement of sandblasting, arranges multiple sand jet outlet simultaneously, can spray by carrying out evenly, reduce sandblasting dead angle；According to the shape adjustment guide plate 22 of mould, sand grains can be sprayed toward assigned direction simultaneously.
In the specific implementation, in order to avoid part the most recessed than excessive and cannot be the most compressing, top board 7 bottom be provided with a plurality of be distributed in length and breadth flexible protruding 24, flexible protruding 24 be connected with independent minitype cylinder 23 respectively below, minitype cylinder 23 electrically connects with control module；Flexible protruding 24 is consistent with the lower horizontal face of top board 7 when regaining.Meanwhile, in order to avoid upper cylinder pressure 9 conflicts mutually with minitype cylinder 23 position, upper cylinder pressure 9 is connected outside top board 7 by gear frame 20.By stretching out flexible protruding 24, the mould that concavity is bigger can be regulated, the deep recessed ratio making its deeper recess is maintained at OK range, can be prevented effectively from the sand grains skewness of this type of mould, the mould different parts degree of packing is inconsistent when causing die mould problem reduces defect rate.When the local calculating mould is deep recessed than during more than threshold value, (in the specific implementation, threshold value can pre-set；In the present embodiment, threshold value can be set to 0.75), what regulation minitype cylinder 23 made top board 7 bottom corresponding with mould flexible protruding 24 extend out to predeterminated position, so can ensure that when penetrating sand recess is unlikely to penetrate sand too much, thus after causing recess compacting, the degree of packing is more than other positions, affects the stability of whole sand mold.
As shown in Figure 5, lower platen is cleaned for convenience in pushing away mold process, it is provided with below raising middle flask push rod 18 and pushes away tringle 13 and push rod cylinder 29, push away tringle 13 and be arranged on push rod cylinder 29 front end, push away tringle 13 front end and be provided with gas hole 25, push rod cylinder 29 is connected with gas hole 25, pushes away tringle 13 front end and is additionally provided with the hairbrush 26 for cleaning.Thered is provided by push rod cylinder and blow, or driving pushes away tringle and advances, and utilizes the hairbrush of front end to carry out cleaning lower platen surface, can improve and make the smooth shape of precision and bottom of sand mold next time, it is to avoid be bonding.
In the specific implementation, in order to export sand mold to next machining area more easily, crane 19 tail end can also connect transmission system.Owing to sand mold is more fragile, being susceptible to vibration normal through forklift transport, damage sand mold, by the transmission system of integration, it is possible to effectively reduce collision, the sand mold reduced in tradition course of conveying damages.
In the specific implementation, improving and penetrate to reduce dead angle further and be additionally provided with a plurality of bleeding point 27 with the position of sand jet outlet 16 symmetry on sand efficiency, cope 5 and drag box 3, bleeding point 27 is connected to air pump by pipeline.The most each bleeding point 27 is also equipped with independent control valve 28；Pumping process advantageously forms negative pressure, improves and penetrates sand speed, increases the degree of packing of sand mold, can guide sand grains simultaneously, reduces dead angle and husky hole.
In the present embodiment, the position of sand jet outlet symmetry is additionally provided with a plurality of bleeding point 27, is taken away the injection of the negative pressure quickening sand grains that air is formed by air pump；When mould is provided with the turning away from sand jet outlet, part is open at the bleeding point of mould corner vicinities, guides sand grains to enter the turning that normal injection cannot arrive at.
The above; it is only preferred embodiment of the present utility model; not in order to limit this utility model, every any trickle amendment, equivalent and improvement made above example according to technical spirit of the present utility model, within should be included in the protection domain of technical solutions of the utility model.
