Description

A kind of casting for piston mould

Technical field

The utility model is related to casting mould technical field, and more particularly, to a kind of simple production process, production efficiency are high, casting The casting for piston mould that part cooling velocity is uniform, casting hardness uniformity is high.

Background technology

Casting mould refers to the planform in order to obtain part, makes part with the material that other are easily molded in advance Planform, then puts into mould again in sand mold, is then the formation of a sky the same with design of part size in sand mold Chamber, then pour into a mould mobility liquid in the cavity, just can be formed and mold shape structure complete after the solidification of this liquid cooling The part of sample.

The process program being bilayer model of domestic cast pistons at present, as shown in Figure 1, it includes rising head 01, casting Part model 02, mud core dividing plate 03, its cast model adopts upper and lower two-layer setting, is provided with mud core dividing plate between two-layer cast model 03, although this scheme product yield is high, but still there are a lot of shortcomings:

1st, because the cast model in single mode is more so that the cooling velocity in the middle of model and edge is uneven, final appearance The hardness of cast form being also easy to produce foundry goods is uneven.

2nd, because this scheme needs lower core it is therefore necessary to increase the operation of one core making, and make under every mould Core also reduces operating efficiency, also can improve, using core, the ratio that foundry goods produces the defects such as sand holes simultaneously.

3rd, because this scheme must be using the feeding scheme of deep cast gate, after the blank dead head that therefore final production goes out separates Not only must waste time and energy through grinder buffing in surface, and a large amount of dusts producing also result in very big impact to environment.

Further, since product requirement chemical composition difference is larger, it is provided with multiple foundry goods due in every mould, as special in do not taken Measure easily causes product batch mixing.The method that other producers are mainly utilized in die face quarter cloudy word is distinguish between, this side Method after long-term use, is easy to carry molding sand secretly in groove of carving characters, and causes sand holes defect；If any mark is not added with foundry returns simultaneously Show, will also result in foundry returns difficult management, the product quality in later stage is impacted.

As fully visible, need a kind of new casting for piston device at present, to simplify production technology, improve production efficiency, to make Foundry goods cooling velocity is uniform, casting hardness uniformity improves, and can simply distinguish the specification of each product, facilitates the pipe of foundry returns Reason.

Content of the invention

The utility model is directed to above-mentioned the deficiencies in the prior art, there is provided a kind of casting for piston mould, its production technology letter Single, production efficiency is high, and foundry goods cooling velocity is uniform, casting hardness uniformity is high, and can simply distinguish the specification of each product, convenient The management of foundry returns.

For solving problems of the prior art, the concrete technical scheme that the utility model adopts is:

A kind of casting for piston mould, it includes template, side by side in order located at multiple casting patterns of template bottom, described casting Modeling type is arranged for individual layer, and described casting pattern is threadingly attached in template, and the center of described template is provided with down gate, institute State and be connected by multiple running channels between multiple casting patterns and down gate.

Preferably scheme, the top of the plurality of running channel (rising head) is equipped with the strip projected parts for distinguishing product specification.

Further preferred scheme, the end face of described casting pattern is equipped with the convex annular for distinguishing each product specification Rise.

Scheme still more preferably, is equipped with steady mould passive to mould at the bottom corner of described template Post.

Scheme still further preferably, is bolt connection between described casting pattern and its running channel.

It is provided with multiple steam vents for being exhausted to foundry goods inside described template.

By adopting such scheme, a kind of casting for piston mould of the present utility model compared with prior art, imitate by its technology Fruit is:

1st, cast model single layer cloth is postponed by the utility model, makes the cooling velocity of all foundry goods basically identical, foundry goods Hardness of cast form uniformity greatly improves.

2nd, cast model is provided with annular bar, and it solves the problems, such as the differentiation of product, also solves quarter positive word to the later stage The infringement to cutter for the product cutting.

3rd, rising head is provided with strip projection, and during foundry returns, mark thereon also efficiently solves each specification foundry returns and is difficult to The problem of management, when making to melt down, various materials are unlikely to obscure, and the product quality in later stage will not be impacted.

Specific embodiment

For making the purpose of this utility model, technical scheme and advantage of greater clarity, with reference to instantiation and join According to accompanying drawing, the utility model is further described.It should be understood that these descriptions are simply exemplary, and it is not intended to limit Scope of the present utility model.Additionally, in the following description, eliminate the description to known features and technology, unnecessary to avoid Concept of the present utility model is obscured on ground.

As shown in Figures 2 to 6, a kind of casting for piston technique, casting pattern is set to individual layer arrangement, multiple casting patterns by it Ordered arrangement, down gate is connected by multiple running channels located between the center of casting pattern, down gate and each casting pattern；Each Casting pattern all prevents the shrinkage depression of casting pattern, the method for described flanging feeding using the method for flanging feeding, refers to often adjacent It is provided with a rising head 2 between two casting patterns 1 and carry out feeding.It is equipped with each for distinguishing on the end face of described casting pattern 1 The annular protrusion 3 of product specification, different products can arrange different annular protrusions, as shown in Figure 3.Described rising head 2 upper surface It is equipped with the strip projected parts 4 for distinguishing product specification, different materials can arrange different strip projected parts, as shown in Figure 4.

As shown in Figure 5 and Figure 6, casting for piston mould of the present utility model in the present embodiment, goes out 40 products with every mould As a example, it includes template 5, side by side in order located at multiple casting patterns 1 of template bottom, between described casting pattern and its running channel For bolt connection.Described casting pattern 1 is arranged for individual layer, and described casting pattern 1 is threadingly attached in template 5, described mould The lower central of plate 1 is provided with down gate 10, and the top of described template 1 is provided with down gate seat 12, the plurality of casting pattern 1 with straight Between cast gate 10 pass through multiple running channels be connected, in figure, 6 be running channel 1,7 be running channel 2,8 be running channel 3,9 be running channel 4.Described running channel 1st, the top of running channel 2, running channel 3 and running channel 4 is equipped with the strip projected parts for distinguishing product specification, and its section is as shown in Figure 4.Institute Annular protrusion for distinguishing each product specification is equipped with the end face stating casting pattern 1, as shown in Figure 3.Under described template 5 It is equipped with steady mould post 11 passive to mould at portion corner.Be additionally provided with inside described template 5 multiple for entering to foundry goods The steam vent of row exhaust.
