Abstract

The utility model belongs to the field of mould production and processing and particularly relates to a core shooting machine which is even in sand filling and simple in whole structure. The core shooting machine comprises a machine frame, a mould box, two sand shooting barrels and a sand hopper, wherein the mould box, the sand shooting barrels and the sand hopper are arranged on the machine frame. The two sand shooting barrels are identical and symmetrically arranged on two sides of the mould box. The sand hopper is located in the top of the machine frame. The sand shooting barrels are connected with the sand hopper through respective sand delivering pipes and provided with machine frames through brackets. Outer sides of the sand shooting barrels are provided with pushing cylinder for pushing the sand shooting barrels to eject the mould box to perform the sand filling. The mould box is composed of an upper mould cover and a lower mould box. The top of the upper mould cover is connected with a lifting cylinder. Two sides of the lower mould box corresponding to the sand shooting barrels are provided with sand inlet holes. Sand spraying nozzles are arranged on the sand shooting barrels corresponding to the sand inlet holes. A plurality of electric heating air guiding rods are inserted into the lower mould box. The whole core shooting machine is square. The core shooting machine adopts a mode that synchronous sand filling is performed on the two sides and is high in the sand filling speed, even in sand filling, high in production efficiency and good product quality.

Description

A kind of core shooter

Technical field

The utility model belongs to the die production manufacture field, is specifically related to that a kind of notes sand is even, the simple core shooter of overall structure.

Background technology

Traditional core shooter overall structure irregularity, poor stability, and adopt a top to annotate sand hole and annotate sand, it is irregular to annotate sand, produces greensand density of modes inequality.Like application number 97237386.1 " pillar core shooter "; Disclose a kind of pillar core shooter, between the upper and lower supporting base of frame, be connected with guide upright post, patrix supporting plate, demoulding supporting plate, the bed die supporting plate links to each other with column through fairlead; The spacing adjusting rod in the column outside pass three supporting plates and upper branching holder and with patrix supporting plate Joint; The patrix supporting plate is provided with jet box and links to each other with feed hopper, this core shooter complex structure, and parts are various.

The utility model content

The purpose of the utility model is for addressing the above problem a kind of simple in structure, globality, the uniform core shooter of notes sand to be provided.

The above-mentioned technical purpose of the utility model is achieved through following technical scheme:

A kind of core shooter comprises frame and is arranged at moulding box, blasting unit and the sand hopper on the frame that said blasting unit is identical two, is symmetricly set in said moulding box both sides.

As preferably, said sand hopper is positioned at said frame top.

As preferably, said blasting unit is connected with said sand hopper through the sandpipe that send separately.

As preferably, said blasting unit is arranged on the said frame through carriage.

As preferably, said blasting unit arranged outside is useful on and promotes blasting unit and withstand the promotion cylinder that moulding box is annotated sand.

As preferably, said moulding box is made up of upper mould cover and drag.

As preferably, said upper mould cover top is connected with lift cylinder.

As preferably, the both sides of the corresponding blasting unit of said drag are provided with into sand hole; Correspondence is advanced sand hole and is provided with blast nozzle on the said blasting unit.

As preferably, be interspersed with some electric heating air guide rods on the said drag.

As preferably, said core shooter integral body is square.

In sum, the utlity model has following beneficial effect:

1, these core shooter parts are few, and cost is low;

2, this core shooter adopts both sides to annotate the mode of sand synchronously, and it is fast to annotate sand speed, and it is even to annotate sand, and production efficiency is high, good product quality;

3, this core shooter integral body is square, simple in structure, and compactness is difficult for colliding with, and is safe.

Description of drawings:

Fig. 1 is a core shooter structural representation one;

Fig. 2 is a core shooter structural representation two;

1-blasting unit among the figure, 11-send sandpipe, the 12-carriage, 13-promotes cylinder, 14-blast nozzle, 31-upper mould cover, 32-drag, 33-electric heating air guide rod.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explain.

This specific embodiment only is the explanation to the utility model; It is not the restriction to the utility model; Those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as in the claim scope of the utility model, all receive the protection of Patent Law.

Embodiment:

Shown in accompanying drawing, a kind of core shooter comprises frame and is arranged at moulding box, blasting unit 1 and the sand hopper on the frame that blasting unit 1 is identical two, is symmetricly set in the moulding box both sides.Sand hopper is positioned at frame top.Blasting unit 1 is connected with sand hopper through the sandpipe 11 that send separately.Blasting unit 1 is provided with frame through carriage 12.Blasting unit 1 arranged outside is useful on promotion blasting unit 1 and withstands the promotion cylinder 13 that moulding box is annotated sand.Moulding box is made up of upper mould cover 31 and drag 32.Upper mould cover 31 tops are connected with lift cylinder.The both sides of drag 32 corresponding blasting units 1 are provided with into sand hole; Correspondence is advanced sand hole and is provided with blast nozzle 14 on the blasting unit 1.Be interspersed with some electric heating air guide rods 33 on the drag 32.Core shooter integral body is square.

During production, pour sand into sand hopper, firing switch, upper mould cover 31 cooperates in the effect decline of lift cylinder and drag 32, promote cylinder 13 promotion both sides blasting units 1 and withstand moulding box, blast nozzle 14 with advance the sand hole closed butt joint, begin in moulding box, to annotate sand Cheng Mo; Core machines, and promotes cylinder 13 blasting unit 1 is dragged go back to both sides, and upper mould cover 31 rises, and delivery gets final product.

This production equipment is simple in structure, and good integrity is produced safelyr, and the core density of production is even, and quality is better, and production and processing is convenient, has improved production efficiency.
