Technical field

The present invention relates to mould applications, and in particular to core shooter.

Background technique

It is the overlay film that precoated sand coring is used by hot box process that core shooter, which is called " penetrating sand machine " or " sand shot machine ", Sand molding coremaking equipment.It is widely used in the production of the high-volume higher core for cast of small-sized and appearance requirement, work is former Reason is to be kept for the regular hour in the master pattern for having heated the core sand filling containing phenolic resin, made at core box wall Resin melting in shell core sand and sand grains is bonded together, being formed along core box internal chamber wall has certain thickness mecystasis shell Extra core sand is poured out and then continues to heat certain time by layer, opens core box and ejects shell core to get type wall thickness is arrived The hollow shell core of very little.In order to improve the production work efficiency of core for cast, a kind of Double-station core shooter exists in the prior art, Two dynamic models are set on a core shooter, and a process terminates to complete the production of two core for cast.

But either single-station core shooter or Double-station core shooter, current generally existing core sand during core shooting The problem of being scattered, being not easily cleaned.If things go on like this, core sand can enter among all parts, influence the normal work of core shooter.

Therefore, how existing core shooter is improved, it is made to overcome the above problem, be those skilled in the art urgently The problem solved.

Summary of the invention

It is an object of the present invention to provide a kind of shaping efficiency it is high, core sand is not easy to be scattered, and can be convenient cleaning Double-station core shooter.

To achieve the above objectives, the technical solution adopted by the present invention are as follows: a kind of Double-station core shooter, including left core shooting component With right core shooting component, the left core shooting component and the right core shooting component are symmetrical arranged, and include pedestal and column support, institute It states and is provided with gas bag, sand hopper and sand cylinder on column support, the gas bag is fixedly installed on the column support, and the sand hopper is solid Surely it is set on rear side of the column support, the sand cylinder is slideably positioned in along the longitudinal direction on the column support, the column Sand cylinder cylinder is provided between bracket and the sand cylinder, the sand cylinder cylinder pushes the sand cylinder to be moved forward and backward, the column branch It is additionally provided with pressure head cylinder, the pressure head cylinder and gas bag cooperation on front side of frame, controls the sand cylinder and carries out penetrating sand movement；Institute It states and is provided with cover half, dynamic model on pedestal and molds cylinder, the cover half is fixedly installed on the pedestal, and the dynamic model is along left and right Direction is slideably positioned on the pedestal, and the molding cylinder is set between the pedestal and the dynamic model, for driving Dynamic model is stated to move left and right；It is characterized by:

Sand cylinder lower end, which is provided with, penetrates head assembly, and the head assembly of penetrating includes cylinder, sand ejection board, baffle, flashboard and lock Plate cylinder, the sand ejection board are fixedly installed on the cylinder lower end, core shooting hole are offered on the core shooting plate, and the baffle is fixed Be set in the cylinder and be located above the sand ejection board, offered down on the baffle through slot, the flashboard abutting and It is slideably positioned on the baffle, the flashboard cylinder drives the gate panel slide, offers on the flashboard and passes through slot；Institute State by slot with it is described it is lower be connected to by slot when, the head assembly of penetrating is opened, and the sand cylinder, which can carry out penetrating sand, to be acted；The gear Plate block it is described upper by slot, the flashboard block it is described under when passing through slot, described to penetrate head assembly closure, the sand cylinder can not be into Row penetrates sand movement.

As an improvement, the column support is additionally provided with cleaning assembly, the cleaning assembly includes cleaning cylinder and cleaning Head, the cleaning cylinder rear end are set on the column support, and the cleaning head is fixedly installed on the gas of the cleaning cylinder Cylinder rod front end, the cleaning cylinder can drive the cleaning head to reach the pedestal, for clearing up the core sand being scattered.

Preferably, being provided with air gun head and water gun nozzle on the cleaning head.High pressure gas and cleaning solution can be used respectively It is cleared up, improves cleaning effect.

Preferably, the cleaning cylinder is articulated on the column support, and can fix at an arbitrary position.Conveniently to more A position is cleared up.

Preferably, the flashboard cylinder is fixedly installed on outside the cylinder, the cylinder rod of the flashboard cylinder is passed through The cylinder rod of the cylinder, the flashboard cylinder is fixedly connected with the flashboard by being drivingly connected block.The connection type is simple Reliably.

Preferably, the sand ejection board two sides are provided with loading plate, the cylinder, institute is bolted in the loading plate Sand ejection board is stated to be fixed on the cylinder by loading plate pressing.Sand ejection board is facilitated to load and unload, for periodically to penetrating head assembly Carry out maintenance and cleaning.

Compared with prior art, the invention has the following advantages that due to offering sand-spraying hole in sand ejection board, in sand cylinder from sand After receiving core sand in bucket, before sand cylinder reaches pressure head cylinder (penetrating sand station), core sand can more or less dissipate from core shooting hole It falls.And this programme is being penetrated in head assembly provided with baffle and flashboard, is equivalent to and is being penetrated in head assembly provided with valve, can control The unlatching and closure for penetrating head assembly, avoid core sand from being scattered.In addition, biggish core can also be stopped by slot on baffle and flashboard Sand passes through, and plays the role of filter screen, is avoided that blocking sand-spraying hole.
