Abstract
The utility model belongs to the field of lost foam casting, specifically to a flow dividing sand storage hopper for a production line of the lost foam casting. The flow dividing sand storage hopper comprises a receiving cavity for receiving sand and a fixed frame for fixing the receiving cavity. A feed inlet for feeding is arranged on the receiving cavity and more than two discharge channels are arranged at extended parts in a fork shape downwards in the cavity of the receiving cavity. The flow dividing sand storage hopper overcomes the problem that conventional one sand shakeout position corresponds to one sand storage hopper to cause the increase of production cost, meets the requirement of respectively filling sand of a plurality of sand shakeout positions with one sand storage hopper, and reduces the number of the sand storage hoppers so as to further reduce corresponding sand transporting devices so that the production cost is extremely reduced and the production efficiency is further improved.
Description
Technical field
The utility model belongs to the lost foam casting field, is specifically related to a kind of by-pass type sand storage bin of the mould manufacturing line that is used to disappear.
Background technology
Lost foam casting is called dry sand full mold negative pressure casting again, is referred to as EPC abroad, is one of state-of-the-art foundry technique in the world at present.This method is processed the bubble moulding model earlier by technological requirement, is coated with to hang special high-temperature resistant coating, after the drying; Place special sandbox, insert dry sand by technological requirement again, vibration ramming; Vacuumize casting metals liquid under the state; This moment, the model gasification disappeared, and the molten metal replacement model copies the foundry goods the same with steeping moulding model.In the above-mentioned flow process, Chu Shadou is institute's necessary part wherein, and it mainly acts on the available sand that is to store transportation from sand storage and comes; And through the device that drenches with rain that is arranged at its bottom sand is inserted the sandbox that is arranged in its below when needed, there is following defective in the husky bucket of existing storage more: at first, the existing husky bucket of the corresponding storage in a back-up sand position that is; And for reaching the largest production benefit; Back-up sand position in the actual production often is set to a plurality of, and this just needs the husky bucket of each all corresponding storage, simultaneously; Also need the corresponding sand conveyor installation that increases to realize being connected between the husky bucket of storage and sand storage, productive costs is higher; Secondly, in the real work, be to need the workman sand of inserting in the sandbox to be carried out tiling operation during the sandbox back-up sand on the sandbox limit; Chu Shadou is positioned at directly over the sandbox, and receives factory building height and consider to guarantee that sand can be accurately by inserting among the Chu Shadou in the sandbox that the Chu Shadou bottom is nearer usually with the sandbox distance; The real work space that this has just inevitably compressed the workman causes its operational space narrow and small, is easy to produce constriction; Simultaneously; There is more property at parts of edges and corners in the Chu Shadou bottom, and people and the husky buckets spacing of storage left near, also had big potential safety hazard.
The utility model content
The purpose of the utility model provides a kind of by-pass type sand storage bin simple in structure, can realize a tractor serves several purposes, can effectively improve its work efficiency.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: a kind of by-pass type sand storage bin; Comprise and be used to the fixed support that holds the container cavity of sand and be used for fixing container cavity; Said container cavity is provided with the inlet point that is used for charging, and said container cavity is provided with the tapping channel more than two from its cavity to its forked postponing in below.
The major advantage of the utility model is: after adopting said structure; The problem that the productive costs of having abandoned the corresponding sand storage bin in a traditional knockout position and having caused increases; Realize that a sand storage bin can satisfy the difference back-up sand demand of a plurality of knockouts position, has reduced the sand storage bin number, and then has more reduced corresponding sand conveyor installation; Productive costs is greatly reduced, and has also improved its production efficiency.

The specific embodiment
A kind of by-pass type sand storage bin; Comprise and be used to the fixed support 20 that holds the container cavity 10 of sand and be used for fixing container cavity 10; Said container cavity 10 is provided with the inlet point that is used for charging; Said container cavity 10 is provided with the tapping channel 11 more than two from its cavity to its forked postponing in below, shown in Fig. 1-3.
The forked junction of above-mentioned adjacent tapping channel 11 can be set to multiple structure, as is polyline shaped etc., as long as can realize its sub-sand function.Further preferred version as the utility model: the forked junction arc transition of the adjacent tapping channel 11 of each of the utility model; Above-mentioned structure can be guaranteed not only in actual use that sand can not have and be stained with sticking and do not have the corresponding tapping channel 11 that directly falls into respectively that splashes and realize storing when from sand conveyor installation, falling; Guarantee also simultaneously that its forked junction is force-applied even when receiving the sand impulsive force, guarantee its service life.
Further; For specializing the structure of the utility model, said by-pass type sand storage bin profile is the symmetrical expression structure, and said tapping channel 11 is four; Said tapping channel 11 be symmetrically arranged in container cavity 10 both sides in twos and by its sidepiece to its below layout that postpones, shown in Fig. 1-3.Traditional sand storage bin why can administration of human with constriction with make its narrow and smallization of working space; Bigger reason is that the blanking port of its sand storage bin is all directly vertically postponed and is opened under the container cavity 10; Cause exercisable space, container cavity bottom minimum, also just have big potential safety hazard simultaneously naturally; The utility model has effectively utilized the side spaces of container cavity 10; Make tapping channel 11 be symmetrically arranged in container cavity 10 both sides in twos and by its sidepiece to its below layout that postpones; Container cavity 10 bottoms are adjacent surround naturally between tapping channel 11 outer walls and constitute one section bigger clear area; Can in this zone, realize its sanding operation during staff's practical operation; In other words, thereby the utility model makes its operational space of " dodging " personnel that do that go into operation through its structural development, has also just avoided some problems that above-mentioned traditional sand storage bin occurred; Thereby given the staff loose working environment, the generation of having stopped the potential safety hazard that narrow and small operational space occurred simultaneously.In addition, for making things convenient for the storage sand blanking of tapping channel 11, all big up and small down hopper shape of said tapping channel 11 profiles.
