Abstract

The utility model relates to a cooler core box core shooting machine with a structure that four stand columns are fixed on four corners of a base seat. An upper support plate is fixed on the upper ends of the stand columns. A hopper, an upper mold opening mechanism and an air pocket are respectively arranged on the upper support plate. Four connecting rods used for connecting an upper core box are arranged on the upper mold opening mechanism. The connecting rods penetrate the upper support plate and stretch below the upper support plate. A sand shooting head is fixedly connected with the undersurface of the upper support plate and is connected with the lower portion of the hopper. An air delivery pipe arranged on the air pocket is communicated with the sand shooting head. A vertical guidepost is fixedly and respectively connected with the inner side of each stand columns. An operating platform is arranged movably on the guideposts. A lifting hydro-cylinder used for lifting the operating platform is arranged on the base seat. The cooler core box core shooting machine has the advantages of improving production efficiency, saving production cost, prolonging service life of molds, producing sand cores with accurate dimensions, improving quality of products and reducing rejection rate of castings.

Description

Cold-box core blower
Technical field
The utility model relates to a kind of moulding machine, specifically a kind of cold-box core blower.
Background technology
Cold core box process is through well mixing the resin sand of system at core box injection system and hardened forming, to obtain a kind of moulding process of qualified core under the normal temperature state.The closing precision of conventional cold-box core blower is not high, affects the quality of core; In addition, the installation of core box bed die and patrix, the dismounting also not too convenient.
The utility model content
The purpose of this utility model just provides a kind of cold-box core blower, and the closing precision that existing cold core machine exists is not high to solve, the problem of core box bed die and patrix dismounting inconvenience.
The utility model is achieved in that a kind of cold-box core blower, at the Corner Strapped of base four columns is arranged, and is fixedly connected with frame plate in the upper end of described column, be equipped with respectively on the frame plate on described hopper, on die opening mechanism and gas bag; Die opening mechanism is provided with four connecting rods for core box on connecting on described, and described connecting rod passes and extend into the below of described upper frame plate; The bottom surface of frame plate is fixedly connected with sand-shooting head on described; The bottom of described hopper and described sand-shooting head join, and the appendix on the described gas bag leads to described sand-shooting head; Inboard at described four columns is fixedly connected with respectively upright lead, slidely connects workbench at described lead, and the elevating ram of the described workbench of lifting is housed at described base.
Be provided with Working cart at described workbench, be connected to demoulding stand on the side edge of described base, be provided with the track that connects with described workbench at described demoulding stand, in described demoulding stand, the plunger tip assembly is housed.
The guide-localization mechanism that the utility model moves up and down as workbench with four leads that are fixedly connected with four columns, with cross-under four connecting rods on the upper frame plate as on the guiding mechanism of core box, because upper frame plate also is fixedly connected on four root posts, therefore, closing precision between upper core box and the workbench can be controlled very accurately, obtains thus more accurate core model.
The utility model can move to the demoulding stand from workbench Working cart by demoulding stand is set, and can make things convenient for thus the installation and removal of core box bed die; The plunger tip assembly carries out the demoulding in the recycling demoulding stand, has made things convenient for the demoulding of core model.
The utility model can be enhanced productivity, and saves production cost, prolongs die life, and the size of the core that produces is accurate, is conducive to improve the quality of products, and reduces the percent defective of foundry goods.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, base, 2, upper frame plate, 3, demoulding stand, 4, appendix, 6, the plunger tip assembly; 7, column, 8, lead, 9, workbench, 10, Working cart, 11, guide pin bushing; 12, connecting rod, 13, sand-shooting head, 14, upper die opening mechanism, 15, gas bag, 16, hopper.
The specific embodiment
As shown in Figure 1, at the Corner Strapped of base 1 four columns 7 are arranged, are fixedly connected with frame plate 2 in the column upper end, be equipped with respectively on the upper frame plate 2 hopper 16, on die opening mechanism 14 and gas bag 15.Upper die opening mechanism 14 is frame structure, is provided with the connecting rod 12 of four cross-under in upper frame plate, and the lower end of connecting rod 12 extend into the below of frame plate 2, is used for connecting upper core box.Sand-shooting head 13 is fixedly connected on the bottom surface of frame plate 2.The bottom of hopper 16 and sand-shooting head 13 join, and the appendix 4 on the gas bag 15 leads to sand-shooting head 13.Inboard at four columns 7 is fixedly connected with respectively upright lead 8, and four guide pin bushings 11 on the workbench 9 respectively cross-under make workbench 9 carry out lifting along lead 8 on four leads 8.Elevating ram (not shown) is housed in the middle position of base 1, and the bottom connection of the piston rod of elevating ram and workbench 9 is in order to the elevate a turnable ladder workbench that makes progress.
Be provided with the Working cart 10 of accepting lower core box at workbench 9, along being connected to demoulding stand 3, be provided with the track that can with workbench connect at demoulding stand 3 at a side of base 1, Working cart 10 can be moved back and forth between workbench 9 and demoulding stand 3.When Working cart 10 is hauled out penetrating after the sand workspace between four columns, can be under the outside dismounting of workspace core box.Plunger tip assembly 6 also is housed, so that the cold core mould in the lower core box is ejected conveniently stripped operation in demoulding stand 3.
