Abstract
The utility model discloses a sand shooting device for processing valve cap sand cores, which comprises a sand shooting frame body (1), wherein a plurality of valve cap sand core sand shooting units (2) are arranged in the sand shooting frame body (1); every two adjacent valve cap sand core sand shooting units (2) are communicated with each other through a sand shooting passage (3); and a sand shooting hole (4) is formed in the center of each sand core sand core sand shooting unit (2). The sand core sand shooting device provided by the utility model can process four valve cap sand cores at a time, thereby improving the efficiency of valve cap sand core processing; and one centralized sand shooting hole is arranged for each valve cap sand core, so that the structure is simple, the core ejection and core discharge are facilitated, and a favorable application prospect is achieved.
Description
Technical field
The utility model relates to the placing field, be specifically related to a kind of process the valve gap core penetrate the sand device.
Background technology
The hot box mould is that machine commonly used in the Foundry Production is made core mold, in the prior art, the hot box mould structure that is used for having the valve gap core of the numerous dark apertures of even distribution mainly contains two kinds of vertical-parting and horizontal partings, owing to take the vertical-parting structure, penetrating sand can only be the concentrated sand-spraying hole that concentrates on hot box mould top, but owing to penetrating sand and exhaust reason, be difficult to dark aperture and will penetrate foot, in valve gap core process, often do not use, valve gap core processing is general adopt as shown in Figure 1 existing horizontal parting structure penetrate the sand device, usually adopt the little sand-spraying hole that disperses, namely at the core place of each dark aperture, all settle a sand-spraying hole 101, complex structure is given hot box Mould Machining and coremaking, plunger tip, big difficulty all has been with in knockout and core cleaning, and present core is penetrated the sand device can only penetrate sand one to one, and valve gap core knockout efficient is slow.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provide a kind of process the valve gap core penetrate the sand device, can one go out four valve gap cores, improve the working (machining) efficiency of valve gap core, for each valve gap core a concentrated sand-spraying hole is set, simple in structure, make things convenient for the plunger tip knockout, have a good application prospect.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of process the valve gap core penetrate the sand device, it is characterized in that: comprise and penetrate the sand framework, described penetrating is provided with several valve gap cores and penetrates the sand unit in the sand framework, adjacent valve gap core is penetrated between the sand unit and is connected by penetrating the sand passage, and core is penetrated sand unit center place and is provided with a sand-spraying hole.
Aforesaid a kind of process the valve gap core penetrate the sand device, it is characterized in that: the quantity that the valve gap core is penetrated the sand unit is four, is left and right being evenly distributed on and penetrates in the sand framework.
Aforesaid a kind of process the valve gap core penetrate the sand device, it is characterized in that: the described tetrapod of penetrating the sand framework is equipped with fixed support, is equipped with fixing hole on each fixed support.
Aforesaid a kind of process the valve gap core penetrate the sand device, it is characterized in that: described sand-spraying hole diameter is 3cm.
The beneficial effects of the utility model are: the core that is used for the valve gap casting mold that the utility model provides is penetrated the sand device, can one go out four valve gap cores, improve the working (machining) efficiency of valve gap core, for each valve gap core a concentrated sand-spraying hole is set, simple in structure, make things convenient for the plunger tip knockout, have a good application prospect.
Description of drawings
Fig. 1 be existing horizontal parting structure penetrate the sand device.
Fig. 2 is the structural representation of penetrating the sand device of processing valve gap core of the present utility model.
Fig. 3 is the side view of penetrating the sand device of processing valve gap core of the present utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figures 2 and 3, a kind of process the valve gap core penetrate the sand device, comprise and penetrate sand framework 1, penetrate and be provided with several valve gap cores in the sand framework 1 and penetrate sand unit 2, adjacent valve gap core is penetrated between the sand unit 2 and is connected by penetrating sand passage 3, core is penetrated 2 centers, sand unit and is provided with a sand-spraying hole 4, sand-spraying hole 4 diameters are 3cm, the sand-spraying hole of penetrating the sand device than existing horizontal parting structure is bigger, adopt to concentrate and penetrate sand, the core of each dark aperture on the full valve gap core is penetrated in assurance, simple in structure, the quantity that the valve gap core is penetrated sand unit 2 is four, is a left side, the right side is evenly distributed on to be penetrated in the sand framework 1, the quantity that the valve gap core is penetrated sand unit 2 is four, be a left side, the right side is evenly distributed on to be penetrated in the sand framework 1, can one goes out four valve gap cores, improves the working (machining) efficiency of valve gap core, the tetrapod of penetrating sand framework 1 is equipped with fixed support 5, is equipped with fixing hole 6 on each fixed support 5.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
