Abstract
The utility model relates to a salt core compacting tool set designed by a proportional cavity. The salt core compacting tool set comprises an upper compression die, a lower compression die outer ring and a lower compression die inner ring; and the tool set comprising the lower compression die outer ring and the lower compression die inner ring comprises a die cavity of a salt core blank forming part and a die cavity of a compacting stroke which are proportional. The salt core compacting tool set meets the standardization design of various salt core blank compacting tool sets; when the salt core compacting tool set designed by the proportional cavity is used for compacting the salt core blank, the dense salt core blank can be obtained by adopting the specific compacting pressure with the same standard; when the salt core is compacted, the weight of the salt material does not need to be weighted every time, the volume of the die cavity decides the adding weight of the loose salt material; the salt material added into the tool set cavity does not need to be evenly processed by manpower; and after the tool set is internally added with the salt material, the qualified salt core blank can be compacted according to the authorized pressure. The production efficiency and the utilization rate of devices are increased by 2 to 3 times; therefore the salt core compacting tool set has very high application value.
Description
Technical field
The utility model relates to a kind of salt core compacting tool set, relates in particular to a kind of salt core compacting tool set of ratio cavity design of aluminium piston water soluble salt element.
Background technology
Along with the raising of diesel engine strengthening degree, thermic load and mechanical load that piston is born increase considerably.For guaranteeing that piston crown has enough intensity and reduces its thermic load, must piston be forced to cool off at top land near near cold oil road in producing with water-soluble core first and second road annular groove.Cold oil road structure can reduce the temperature at top land and annular groove position in adopting, and the temperature at each position of piston is controlled in the rational limit value, has guaranteed the functional reliability of piston and piston ring.Water-soluble core generally is meant with the water soluble salt to be the salt core that matrix is made, and is characterized in meeting water-soluble separating, and is convenient to depoling.Aluminium casting for piston process adopts sodium chloride compacting salt core more and is cast into piston blank and forms interior cold oil road.
Because the shape and size in cold oil road have relative uniformity and comparativity in the piston, the mould parting method of compacting salt core tends to consistent mostly, generally presses small end R arc center circumferential somatotype, sees shown in Figure 1.Because the press device difference of selecting for use, the connection locate mode of mould and equipment may be different.The key of mould design is how to determine the size of mold cavity, and mold cavity comprises the mold cavity volume of salt core blank forming part in the mould and the mold cavity volume of pressing stroke.At present, the cavity design of salt core compacting tool set is a kind of design more than needed, before coming into operation, passes through by mould the relation of weight, pressing pressure and the corresponding salt core blank dimension of the required loose sodium chloride salt material of verification experimental verification, during production before a salt core of the every compacting blank, accurately measure required salt material weight with electronic scale, then the salt material is added in the mold cavity, and manual mode evenly distributes the salt material pressure compacting salt core during then according to test with instrument.Before using, to test by this mould obtaining process data, operation complexity in the use, and whether the salt core blank quality of compacting is influenced uniformly by the salt material in the mold cavity and has than great fluctuation process.
Summary of the invention
The utility model purpose is stated the deficiencies in the prior art in order to solve exactly, and a kind of salt core compacting tool set of ratio cavity design is provided, and has satisfied the standardized designs of various salt core blank compacting tool sets.Simultaneously, adopt this compacting tool set, use the sodium chloride raw material of certain limit granularity, adopt the unit are pressing pressure of relative broad range, can obtain fine and close salt core blank, and can guarantee that salt core blank has certain processing capacity.
The purpose of this utility model is to adopt following technical proposals to realize:
A kind of salt core compacting tool set of ratio cavity design, it comprises top die and dip mold outer ring, dip mold inner ring.The die cavity that dip mold outer ring and dip mold inner ring are formed comprises the die cavity of salt core blank forming part and the die cavity of pressing stroke.
The mold cavity volume of described shaped portion requires to calculate according to salt core compact dimensions, the volume of described pressing stroke die cavity is by 80% design of shaping part mold cavity volume, adopt the unit pressure compacting salt core blank of 125～160MPa during compacting, its inherent quality optimum, this moment the salt core in this pressure limit, suppressed density stabilized at 1.96g/cm
3～1.98g/cm
3About.
The unit pressure of described 125～160MPa is that forcing press is applied to the unit pressure on the salt core blank vertical projection area.
Before using, need not test the salt core compacting tool set that adopts the utility model to make the weight of required loose sodium chloride salt material, process datas such as pressing pressure, cooperate suitable salter structure (as with salt box etc.) during use, after adding the salt material in the die cavity, blow unnecessary salt material then off along plane on the mould, the weight that when compacting salt core, does not need each weighing salt material, but determined the adding weight of loose salt material with mold cavity volume, simultaneously because the loose salt material is full of mold cavity, reached even distribution, do not need by manually the salt material being carried out uniform treatment, the pressure compacting can suppress qualified salt core blank in accordance with regulations then.The salt core compacting tool set production efficiency and the utilization rate of equipment and installations that adopt the utility model to make have improved 2～3 times, therefore have highly application value, and through promoting checking, successfully are used for the batch process of various salt core products as design specification, and be respond well.
Description of drawings
Fig. 1 is the utility model cross-section structure sketch;
Wherein 1. top dies, 2. dip mold outer ring, 3. dip mold inner ring.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, dip mold outer ring 2 is a standing part, generally is connected with press bench, and dip mold inner ring 3 is connected with the forcing press ejecting mechanism, and top die 1 is connected with the slide unit that forcing press principal pressure cylinder drives.Dip mold outer ring 2 and dip mold inner ring 3 are along lower end R arc center circumferential somatotype, and both form mold cavity jointly, comprise the die cavity of salt core blank forming part and the die cavity of pressing stroke.The die cavity of h1 height is the mold cavity volume of shaped portion, is the volume of the salt core blank after suppressing; The die cavity of h2 height is the volume of pressing stroke die cavity, and top die 1 enters the mold cavity volume of dip mold part when being compacting.The mold cavity volume of shaped portion requires to calculate according to salt core compact dimensions, and the mold cavity volume of pressing stroke is by 80% design of the mold cavity volume of the part that is shaped.
Claims (2)
1. the salt core compacting tool set of a ratio cavity design, it comprises top die, dip mold outer ring and dip mold inner ring, it is characterized in that: the mold cavity that described dip mold outer ring and dip mold inner ring are formed comprises the die cavity of salt core blank forming part of proportional relation and the die cavity of pressing stroke.
2. the salt core compacting tool set of ratio cavity design according to claim 1 is characterized in that: the volume of described pressing stroke die cavity is 80% of a shaped portion mold cavity volume.
