Description
Technical field
The utility model relates to a kind of preparation facilities of casting mould, particularly prepares the device of the thin-walled sand core of water jacket of automobile engine cylinder-body.
Background technology
The thin-walled sand core of water jacket of common automobile engine cylinder-body has difficult forming aborning, ejects problems such as difficulty.In existing mould designing technique, arranging exhaust air plug or increase drafting angle, increase surface smoothness outside the thin-walled core are guaranteeing to lean on the common round top rod on next door that core is ejected mold cavity under the complete prerequisite of core moulding usually.There is following shortcoming in the mould of this structure in actual production: 1, the thin-walled place moulding of core is better, causes core and cavity surface to fit firmly, easily pushes up core bad when ejecting; 2, Duan Lie core is difficult to cleaning, the maintenance inconvenience when causing the frock online production in die cavity; 3, because the region limits of die cavity, can only be during the arranging exhaust air plug from the back side the anti-venting plug of beating, if venting plug is blocked by sand aborning, will cause defectives such as the fluffing of moulding sand, and be difficult to venting plug is cleared up, be unfavorable for producing continuously in enormous quantities.
The utility model content
The utility model purpose: at the problems referred to above, the purpose of this utility model provide a kind of rational in infrastructure, processing is simple, produce the device of the thin-walled sand core of water jacket of stable, easy to maintenance preparation automobile engine cylinder-body.
Technical scheme: a kind of device for preparing the thin-walled sand core of water jacket of automobile engine cylinder-body, comprise that cylinder body inserts, cope match-plate pattern, lower bolster and ejecting mechanism; thin-walled core and described lower bolster are located matched moulds by round top rod; cope match-plate pattern is pressed together on thin-walled core top; position relative with the thin-walled of described thin-walled core on described lower bolster has the groove that ejecting mechanism is set; in the middle of described thin-walled core and the described lower bolster by fillings of inserting of described cylinder body; described ejecting mechanism comprises height release link and the retinue push rod that is fixed on the push rod base; described retinue push rod is over against thin-walled; described height release link is provided with back-moving spring, and described height release link top is fixed with the cope match-plate pattern inboard.
For making ejecting mechanism when moving with frock folding mould, the thin-walled place is stressed evenly, the height release link is symmetricly set on the both sides of described retinue push rod.
Described retinue push rod is provided with the line cut-in groove, and easy to exhaust helps the moulding herein of thin-walled core.
Height release link and retinue push rod removably connect by bolt, screw and the formation of push rod base, be convenient to damage of components after, dismounting and change effectively reduces the maintenance cost of mould.
Groove leaves vacant stroke on the degree of depth, for the motion of ejecting mechanism provides the stretching motion space.
Described ejecting mechanism that quantity is set is consistent with the quantity of described thin-walled, at the thin-walled place of thin-walled core such ejecting mechanism is set all, guarantee the yield rate of core.
The gap is left at ejecting mechanism assembling position, is used for exhaust, thereby can better guarantees the Forming Quality of core.
Beneficial effect: compared with prior art, the utility model has the advantages that simple and reasonable, make full use of the characteristic of spring, guarantee during the folding mould that ejecting mechanism and other push rods are synchronized with the movement, make that to eject balance of movement reliable, guarantee the moulding of thin-walled sand core of water jacket and eject steadily the percent defective of reduction core.Itself can separate ejecting mechanism and template, is convenient to processing, repair and replacement.
Description of drawings
The half sectional view of mould when Fig. 1 is the matched moulds state;
The half sectional view of mould when Fig. 2 is die opening state.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of device for preparing the thin-walled sand core of water jacket of automobile engine cylinder-body, comprise that cylinder body inserts 2, cope match-plate pattern 9, lower bolster 3 and ejecting mechanism; thin-walled core 1 and described lower bolster 3 is by round top rod 8 location matched moulds; cope match-plate pattern 9 is pressed together on thin-walled core 1 top; position relative with the thin-walled 12 of described thin-walled core 1 on described lower bolster 3 has the groove 10 that ejecting mechanism is set; insert by described cylinder body in the middle of described thin-walled core 1 and the described lower bolster 3 and 2 fill; it is characterized in that: described ejecting mechanism comprises height release link 4 and the retinue push rod 6 that is fixed on the push rod base 7; described retinue push rod 6 is over against thin-walled 12; described height release link 4 is provided with back-moving spring 5, described height release link 4 tops and cope match-plate pattern 9 inboard fixing.
Height release link 4 and retinue push rod 6 form by bolt, screw and push rod base 7 and removably connect, and height release link 4 is symmetricly set on the both sides of described retinue push rod 6, and thin-walled 12 just in time is positioned in the middle of two height release links 4 of symmetric arrangement.Thin-walled 12 places, every place all are provided with ejecting mechanism, and gap 11 is left at ejecting mechanism assembling position.
