Abstract
The utility model relates to a brake head swage tectorial membrane sand device, its characterized in that: include case card, last swage, lower swage, the gating system, rising head, core, cover the sand bed, the case card sets up at last swage under and on opposite side of swage for swage and lower swage on the chucking, the opposite side of going up swage and lower swage sets up casting machine, it sets up the rising head to go up the swage top, the swage inner wall sets up the core down, it forms the brake head die cavity jointly to go up swage, lower swage and core, the sand bed is covered in the setting of brake head die cavity inner wall. The beneficial effects of the utility model are that: the production efficiency of this device is high, and production cycle reduced to 1 day by original 7 days, and the per capita output is original 5 times, the molding raw and other materials are only two kinds, low in production cost, and only the swage heating is power consumptive, energy -concerving and environment -protective, product rate and product percent of pass are high, the production environment is good, low in labor strength, but the tectorial membrane sand core resting period is long, and stability is high.
Description
Technical field
The utility model relates to brake head lock casting technology field, specifically a kind of brake head swage precoated sand device.
Background technology
Rail wagon brake system parts brake head, material is cast steel, and shape matching is complicated.At present, complete its casting technique of railway freight-car industry be precision-investment casting and shell mould precoated sand fabrication technique casting.Brake head full form casting process, production process is many, cycle minimum needs 7 days, and its mechanization degree is low, labour demand is large, and technique uses material to reach kind more than 10 altogether, and percent defective is high, and manufacturing cost is high, and owing to using ammonium chloride sclerosis, hydrochloric acid Lasaxing Oilfield technique, contaminated environment; Brake head shell mould precoated sand fabrication technique, the shortcomings such as resin-coated sand shell mould yielding and venting quality difference, cause finished product rate low.
Utility model content
Not enough for above-mentioned prior art, the utility model provides a kind of brake head swage precoated sand device.
The brake head swage precoated sand device that the utility model provides is achieved through the following technical solutions:
A kind of brake head swage precoated sand device, it is characterized in that: comprise case card, upper swage, lower swage, running gate system, rising head, core, cover layer of sand, described case card is arranged on swage and lower swage opposite side, for clamping upper swage and lower swage, the opposite side of described upper swage and lower swage arranges casting system, described upper swage top arranges rising head, described lower swage inwall arranges core, described upper swage, lower swage and core form brake head die cavity jointly, and described brake head die cavity inwall arranges and covers layer of sand.
The described precoated sand thickness covered on layer of sand is 5-8mm.
The beneficial effects of the utility model are:
1, the production efficiency of this device is high, and the production cycle was reduced to 1 day by original 7 days, and per capita output is original 5 times;
2, this device moulding raw material only have two kinds, and production cost is low, and only have swage to heat power consumption, energy-conserving and environment-protective;
3, yield rate and product percent of pass high;
4, production environment is good, and labour intensity is low;
5, precoated sand core can the resting period long, stability is high;
6, rising head and exhaust passage are set, can effectively avoid the defects such as steel-casting shrinkage cavity, crackle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1 for case card, 2 for upper swage, 3 for lower swage, 4 for running gate system, 5 for rising head, 6 for core, 7 for brake head, 8 for covering layer of sand.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of brake head swage precoated sand device as shown in Figure 1, it is characterized in that: comprise case card 1, upper swage 2, lower swage 3, running gate system 4, rising head 5, core 6, cover layer of sand 8, described case card 1 is arranged on swage 2 with on lower swage 3 one opposite sides, for clamping upper swage 2 and lower swage 3, the opposite side of described upper swage 2 and lower swage 3 arranges casting system 4, described upper swage 2 top arranges rising head 5, described lower swage 3 inwall arranges core 6, described upper swage 2, lower swage 3 and core 6 form the brake head die cavity of casting brake head 7 jointly, described brake head die cavity inwall arranges and covers layer of sand 8.
Further, the precoated sand thickness covered described on layer of sand 8 is 5-8mm.
Further, described upper swage 2 arranges exhaust passage.
The above embodiment only represents embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to the utility model protection domain.
