Abstract
The utility model provides a spline type mould. The spline type mould comprises a rack, wherein the rack is provided with two horizontal air cylinders; each horizontal air cylinder is connected with an outer mould; a lower hanging plate is arranged below the rack; the lower hanging plate is connected with the rack by a connection guide column; a lower air cylinder is arranged at the bottom of the lower hanging plate; the lower air cylinder drives the lower hanging plate to move on the connection guide column; the lower hanging plate is provided with a middle core corresponding to the inner outline and the size of a product; a spline core is arranged at the top of the middle core and the middle core and the spline core are concentric; a base plate is mounted in the middle of the two outer moulds on the rack; and the base plate is provided with an outer circle positioning step and an inner hole positioning hole. According to the spline type mould, a vertical mould opening structure is adopted to guarantee that the spline and the product are concentric and a previous spline eccentric problem is solved; meanwhile, the spline and the middle core, and the mould are in a movable connection structure, so that the problems that as the steel spline is overheated, the mould is clamped and the core is difficult to draw are solved; furthermore, the air cylinder is used for opening the mould and an operator only needs to press a button, so that the mould opening carried out by the air cylinder is faster than manual mould opening and closing; and the working efficiency is greatly improved and the labor force is saved.
Description
Technical field
The utility model relates to Metallic Casting Die & Mold technical field, and being specifically related to a kind of spline is mould.
Background technology
Casting mould is instrument important in metal casting industry, the mould that is workpiece casting for spline is at present all to adopt horizontal mold-opening structure, horizontal die sinking is difficult to guarantee that spline is concentric with product, easily produce spline eccentricity issues, and the mould of wherein casting spline parts is to be all fixed on whole mould, can cause so the overheated mould that causes of spray of molten steel key to hold tightly, the difficult problem of loosing core.In addition existing spline is that mould adopts artificial or half mechanically actuated mode mostly, and production efficiency is low, and cost of labor is high.
Summary of the invention
It is mould that the utility model provides a kind of spline, the spline bias, the difficulty of loosing core and the low problem of production efficiency that to solve prior art, exist.
The utility model comprises frame, solving the technical scheme that its technical problem adopts is that two horizontal air cylinders are installed in frame, each horizontal air cylinder is connected with an external mold, frame below arranges lower boatswain chair, lower boatswain chair is connected with frame by connecting guide pillar, lower boatswain chair bottom arranges lower cylinder, lower cylinder drives lower boatswain chair to move on connection guide pillar, the corresponding SMIS of the in-profile of installation and product and size on lower boatswain chair, SMIS top arranges multiple key core, SMIS is concentric with multiple key core, chassis of installation in frame in the middle of two external molds, chassis is provided with excircle orientation step and Internal hole positioning hole concentric with in-profile to guarantee product exterior contour.
Above-mentioned horizontal air cylinder is fixed in frame by air cylinder support.
Horizontal air cylinder promotes external mold die sinking matched moulds, and lower cylinder is used for connecting SMIS, plays the loosing core effect of core that pushes away, connect guide pillar for connection frame and lower boatswain chair and guarantee frame and lower boatswain chair between the depth of parallelism, thereby the overall dimensions of assurance product.
The utility model adopts perpendicular mold-opening structure to guarantee that spline and product are concentric, has solved spline eccentricity issues in the past; Spline and SMIS and mould are movable connection structure simultaneously, having solved the overheated mould that causes of spray of molten steel key holds tightly, the difficult problem of loosing core, in addition the utility model adopts cylinder die sinking, operator only need to pull button, and faster than artificial folding mould, greatly improved production efficiency, save labour.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic top plan view of the present utility model.
In figure, 1 frame, 2 horizontal air cylinders, 3 external molds, 4 times boatswain chairs, 5 lower cylinders, 6 SMIS, 7 multiple key cores, 8 connect guide pillar, 9 air cylinder supports, 10 chassis, 11 excircle orientation steps, 12 Internal hole positioning holes.
The specific embodiment
As depicted in figs. 1 and 2: a kind of spline is mould, comprise frame 1, two horizontal air cylinders 2 are installed in frame 1, horizontal air cylinder 2 is fixed in frame 1 by air cylinder support 9, each horizontal air cylinder 2 is connected with an external mold 3, frame 1 below arranges lower boatswain chair 4, lower boatswain chair 4 is connected with frame 1 by four connection guide pillars 8, lower boatswain chair 4 bottoms arrange lower cylinder 5, lower cylinder 5 drives lower boatswain chair 4 to move on connection guide pillar 8, the corresponding SMIS 6 of the in-profile of installation and product and size on lower boatswain chair 4, SMIS 6 tops arrange multiple key core 7, SMIS 6 is concentric with multiple key core 7, chassis 10 of installation in frame 1 in the middle of two external molds 3, chassis 10 is provided with excircle orientation step 11 and Internal hole positioning hole 12 concentric with in-profile to guarantee product exterior contour.
Claims (2)
1. a spline is mould, comprise frame, it is characterized in that installing in frame two horizontal air cylinders, each horizontal air cylinder is connected with an external mold, frame below arranges lower boatswain chair, lower boatswain chair is connected with frame by connecting guide pillar, lower boatswain chair bottom arranges lower cylinder, lower cylinder drives lower boatswain chair to move on connection guide pillar, the corresponding SMIS of the in-profile of installation and product and size on lower boatswain chair, SMIS top arranges multiple key core, SMIS is concentric with multiple key core, chassis of installation in frame in the middle of two external molds, chassis is provided with and excircle orientation step and Internal hole positioning hole.
