CN204770515U - Casting sand box with adjustable it is novel - Google Patents

Abstract

The utility model relates to a casting sand box with adjustable it is novel (non - " V " method, disappearance mould class sand box) belongs to mechanical foundry technology field. Its technical scheme is: a sand box left side frame and sand box right side framework components utilize bolt, nut, packing ring to connect and the fastening that casting sand box with adjustable it is novel is welded by steel sheet, lug. Sand box right side frame slightly is greater than sand box left side frame on height and width, produce respectively in sand box left and right frame both sides and arrange the exhaust hole that the law is the same, the aperture unanimous, correspond each other, and left and right framework composition gets up the sand box, and like the drawer, bolt, nut, packing ring are used to in certain extent relative movement to suitable position, through corresponding exhaust jogged joint and fastening to obtain not unidimensional sand box. The beneficial effects are that: make a pair sand box can be applicable to the mould that more sizes are different to reach the preparation quantity that reduces the sand box, the mesh that reduces casting binder use amount.

Description

A kind of novel adjustable casting sandbox

Technical field

The utility model relates to a kind of novel adjustable casting sandbox (non-" V " method, evaporative pattern class sandbox), belongs to machine casting technical field.

Background technology

At present, the monolithic construction that conventional casting sandbox (non-" V " method, evaporative pattern class sandbox, as Fig. 1) all adopts appearance and size to change, a set of sandbox is only applicable to several secondary mould that a secondary mould or appearance and size are close.Because sandbox appearance and size cannot change, in process of production, generally all according to the difference of die boundary dimensions, produce various corresponding special shape mo(u)lding box.But the cost of manufacture of special shape mo(u)lding box is high, the cycle is long, and a large amount of special shape mo(u)lding boxs also needs large-area storage space.Therefore in real production process, usually all can run into and have to use large sandbox to produce the situation of miscellaneous goods, thus (binding agent of casting has multiple: 1. swelled ground and clay to cause binding agent, 2. waterglass, 3. oil based binder, 4. synthetic resin) huge waste, make production cost remain high.

In with in 2012 in 2013, Jiang Tong group (Dexing) casts Co., Ltd's Casting Factory in the process making acid-proof pipe (use phenolic sand molding), because most of acid-proof pipe bore is more or less the same, but length dimension is different, when there is no special shape mo(u)lding box, large sandbox can only be utilized to make miscellaneous goods, thus cause the huge waste of binding agent (resin and curing agent).

Summary of the invention

The purpose of this utility model is just to provide a kind of novel adjustable casting sandbox (non-" V " method, evaporative pattern class sandbox), solves the problems of the technologies described above.

The technical solution of the utility model is: the sandbox left frame be welded into by steel plate, hanger is corresponding with sandbox correct frame size, sandbox correct frame is slightly higher than sandbox left frame, slightly wide, after combination, all slightly gap between the upside of the left and right framework of sandbox and between the side on both sides, that face that the left and right framework of sandbox contacts with mould shaping plate is in same level, and can relative movement as drawer.Produce in the both sides of the left and right framework of sandbox that arrangement regulation is identical respectively, steam vent that aperture is consistent, mutually corresponding, left and right for sandbox framework composition is got up, according to the difference of die size size, as drawer, relative movement is to correct position within the specific limits, make sandbox both sides coincide part steam vent be in concentric circles position, then use bolt, nut, packing ring, to be connected by corresponding steam vent and fastening, thus obtain the different sandbox of size.

The beneficial effects of the utility model are: according to need of production, change sandbox size within the specific limits, make a secondary sandbox can be applicable to the different mould of more sizes, to reach the production quantity reducing sandbox, the object reducing binding agent use amount, thus shorten the production cycle, save production cost, decrease the stacking place of production of sandbox simultaneously.

Accompanying drawing explanation

Fig. 1 is conventional monoblock type casting sandbox (non-" V " method, evaporative pattern class sandbox).

Fig. 2 and Fig. 3 is the structural representation before and after the utility model size regulates.

Fig. 4 is the comparison diagram (do not use bolt, nut, packing ring fastening) before and after the utility model size regulates.

Fig. 5 and Fig. 6 is two parts of the present utility model: sandbox left frame (as Fig. 5), sandbox correct frame (as Fig. 6).

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail, known with reference to Fig. 2, Fig. 3, Fig. 4, the sandbox left frame (as Fig. 5) that the utility model is welded into by steel plate, hanger respectively and sandbox correct frame (as Fig. 6) forms, utilize the connection of bolt, nut, packing ring and fastening.The left and right framework of sandbox (as Fig. 5,6) size corresponding (as Fig. 4), namely sandbox correct frame is slightly higher than sandbox left frame, slightly wide, after combination, all slightly gap between the upside of the left and right framework of sandbox and between the side on both sides, that face that the left and right framework of sandbox contacts with mould shaping plate is in same plane, and can relative movement as drawer (as Fig. 4).Left at sandbox, correct frame is (as Fig. 5, 6) it is identical that both sides produce arrangement regulation respectively, aperture is consistent, the steam vent (as Fig. 4) of mutual correspondence, sandbox is left, correct frame is (as Fig. 5, 6) combine, according to the difference of die size size, as drawer, relative movement is to correct position within the specific limits, make sandbox both sides coincide part steam vent be in concentric circles position (as Fig. 4), then bolt is used, nut, packing ring, to be connected by steam vent and fastening, thus obtain the different sandbox of size (as Fig. 2, 3), to meet the needs of the different mould of portion size, make a secondary sandbox can be applicable to more mould.

Claims (2)

1. novel adjustable casting a sandbox, comprising: the sandbox left frame be welded into by steel plate, hanger and sandbox correct frame, use each other bolt, nut, packing ring connection and fastening.

2. one kind as claimed in claim 1 novel adjustable casting sandbox, in contour structures and use procedure, it is characterized in that: sandbox is left, correct frame size is corresponding, namely sandbox correct frame is slightly higher than sandbox left frame, slightly wide, after combination, sandbox is left, all slightly gap between the upside of correct frame and between the side on both sides, sandbox is left, that face that correct frame contacts with mould shaping plate is in same level, and can relative movement as drawer, left at sandbox, it is identical that the both sides of correct frame produce arrangement regulation respectively, aperture is consistent, the steam vent of mutual correspondence, sandbox is left, correct frame combines, according to the difference of die size size, as drawer, relative movement is to correct position within the specific limits, make sandbox both sides coincide part steam vent be in concentric circles position, then bolt is used, nut, packing ring, by corresponding steam vent connect and fastening, thus obtain the different sandbox of size.
