Description

Casting system

Technical Field

The utility model belongs to the casting field, concretely relates to casting system.

Background

The casting industry is the basic industry of the mechanical industry, the casting plays an important role in the mechanical industry, and the casting technology is one of the main technologies of national economy sustainable development and is the supply side of mechanical products. With the reputations of foreign countries in China, the machinery manufacturing industry is promoted to develop vigorously. However, the casting system in the prior art is mostly used for casting two castings by using one casting system, and the method is difficult to improve the production efficiency on certain molding equipment, personnel and production sites.

At present, the process of casting a plurality of castings by one casting system gradually appears, but defects such as cold shut, overlapping lines and the like often appear, and the quality of the castings is influenced. The reasons for the defects are that the series runner pipes in the casting system for casting a plurality of castings are mostly straight pipes and are connected in the same horizontal direction, so that the flow rate of molten metal is high during the mold filling process, and partial molten metal flows into the next cavity when the molten metal in one cavity is not filled, so that the partially flowing molten metal contacts with the mold wall to be solidified prematurely, and the molten metal which enters the next cavity cannot be fused with the solidified metal layer into a whole, so that the defects of overlapping grains, cold shut and the like are formed at the butt joint of the surfaces of the castings, and the quality of the castings is influenced.

SUMMERY OF THE UTILITY MODEL

In order to solve the defect that the casting system that exists easily appears quality problems such as cold shut, water wave in many foundry goods of simultaneous casting, the utility model provides a casting system.

The utility model discloses a realize according to following technical scheme:

a casting system comprises a runner pipe, a pouring cup and a vertical pouring gate connected with the lower end of the pouring cup, wherein the runner pipe comprises a pipe body, and at least one protruding section with the height higher than the inlet of the pipe body is arranged on the pipe body;

the other end of the vertical pouring gate is connected with one end of the filter box, the other end of the filter box is connected with the inlet end of the horizontal pouring gate, the outlet end of the horizontal pouring gate is communicated with at least one casting channel, the casting channel at least comprises two connecting joints which are connected in series, each connecting joint is provided with a casting end communicated with the cavity, and the adjacent two connecting joints are connected through the pouring gate pipe.

Preferably, the pipe body is V-shaped or U-shaped.

Preferably, the raised section is located at the middle position of the pipe body.

Preferably, the number of the casting channels is more than two, and the casting channels are connected in parallel.

The utility model has the advantages that:

(1) the utility model discloses a V-arrangement runner pipe is used in the casting system of many foundry goods of simultaneous casting, when the molten metal flows into the die cavity, the metal liquid flows to fold the line that next die cavity formed when can avoiding previous die cavity not full, defects such as cold shut, adopt between the die cavity through V-arrangement runner union coupling, at this moment, can guarantee that a die cavity fills up the molten metal smoothly, its unnecessary molten metal is impressed next die cavity through pressure, can obtain the high quality foundry goods of defect such as no fold line, cold shut like this.

(2) The utility model discloses a casting system, under the good condition of assurance foundry goods quality, realized the effect of many foundry goods of a casting system casting, production efficiency in its unit interval has also improved greatly.

Drawings

Fig. 1 is a front view of a runner pipe according to embodiment 1 of the present invention;

fig. 2 is a front view of a casting system according to embodiment 1 of the present invention;

wherein, 1-pouring cup; 2-vertical pouring channel; 3-a filter cartridge; 4-horizontal pouring channel; 5-connecting a joint; 6-a runner pipe; 7-reducing bent pipe; 51-casting end; 61-a tube body; 62-inlet.

Detailed Description

The invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a runner pipe 6 includes a pipe body 61, and the pipe body 61 has at least one raised section with one end higher than an inlet 62 of the pipe body 61.

The tube 61 is V-shaped in this embodiment. The liquid metal pouring device is used in a pouring system for casting a plurality of castings, and can avoid the defects of overlapping grains, cold shut and the like caused by the fact that the liquid metal flows to the next cavity when the previous cavity is not filled.

As shown in figure 2, the casting system comprising the sprue pipe 6 comprises a sprue cup 1 and a vertical runner 2 connected with the lower end of the sprue cup 1, the other end of the vertical runner 2 is connected with one end of a filter box 3, the other end of the filter box 3 is connected with the inlet end of a horizontal runner 4, the outlet end of the horizontal runner 4 is communicated with a casting channel, and the casting channel comprises 3 connecting joints 5 connected in series and a reducing elbow pipe

7, attach fitting 5 and reducing return bend 7 have the casting end 51 with the die cavity intercommunication, and adjacent two pass through between the attach fitting 5 runner pipe 6 is connected, the height of the protruding section of runner pipe 6 is higher than the import 62 of the body 61 of runner pipe 6.

Example 2

Unlike in example 1, the pipe body 61 of the runner pipe 6 is U-shaped.

Example 3

Different from the embodiment 1, the number of the casting channels is two, and the casting channels are connected in parallel.

The working principle is as follows:

the molten metal is poured into the pouring cup 1, then passes through the vertical pouring channel 2 and the filter box 3, and is filtered by the filter box 3, so that residues are filtered, and then reaches a first cavity through the horizontal pouring channel 4 and the connecting joint 5, due to the existence of the protruding section, the molten metal cannot enter a next cavity, after the first cavity is completely filled with the molten metal, the subsequent molten metal can be pressed into the second cavity connected with the second connecting joint 5 through the first pouring channel pipe 6 until the second cavity is filled with the incoming molten metal, and so on, the redundant molten metal flows into the following cavity after the previous cavity is filled with the molten metal in sequence until the last cavity is filled with the molten metal.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are considered to be within the scope of the invention as defined by the following claims.
