Abstract
The utility model relates to a casting sand mold structure of a cam case. The cam case comprises a base plate, case walls and two pairs of fixing holes, wherein the case walls are arranged on the edges and the middle part of the base plate; the two pairs of fixing holes are formed in the case walls and used for fixing a transmission mechanism and an open arm component respectively; the casting sand mold structure comprises a lower sand case, an upper sand case and a cavity; the upper sand case is clamped with the lower sand case in a sealing manner; the cavity is formed in an interface between the upper sand case and the lower sand case and corresponds to the cam case structure; the casting sand mold structure also comprises a plurality of inner pouring channels, transverse pouring channels and straight pouring channels; the inner pouring channels are arranged in the upper sand case and communicated with the top of the cavity; the transverse pouring channels are arranged in the upper sand case and communicated with the tops of the pouring channels; the straight pouring channels are arranged in the upper sand case, communicated with the transverse pouring channels and used for injection of molten iron. According to the casting sand mold structure of the cam case, the molten iron enters the cavity in a raining manner through the plurality of inner pouring channels which are communicated between the transverse pouring channels and the cavity; the molten iron is even in temperature gradient and exhausts smoothly, so that almost no air holes are formed in the manufacture castings.
Description
Technical field
The utility model belongs to machine casting field, relates to particularly a kind of cam box casting sand type structure.
Background technology
Fly-shuttle loom refers to that take shuttle introduces weft yarn the loom of shed open as weft insertion device, the shortcoming that it has, and vibrations are large, noise is large, machine material loss is many, be unfavorable for high yield.Along with the development of textile industry, general fly-shuttle loom is eliminated gradually, and shuttleless loom has captured rapidly loom market.Shuttleless loom mainly contains the four major types such as rapier loom, gripper shuttle loom, water-jet loom and air-jet loom, by opening mode, can be divided into three kinds of crank connecting link openings, dobby shedding, cam shedding.
Grant number is that the Chinese utility model patent of CN 201952571 U discloses a kind of cam opening device, it mainly comprises cam box, in cam box, be provided with transmission mechanism and open arm component, described transmission mechanism comprises camshaft and some cam bits fixed thereon, and described open arm component comprises opening arm axle and some opening arm sheets fixed thereon.Wherein cam box is used for supporting transmission mechanism and open arm component, therefore require it there is certain intensity, without serious casting flaw.Existing casting sand type structure be the lateral leadin molten iron from die cavity, cold when molten iron is flowed through die cavity top, in the situation that pouring temperature is low, easily produce pore, produce defect.
Summary of the invention
The utility model object is that a kind of casting sand type structure that cam box does not produce pore of casting is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cam box casting sand type structure, described cam box comprises substrate, be located at bottom edge and middle tank wall, be located at two pairs of fixing holes that are respectively used to fixed conveyor mechanism and open arm component on tank wall, described casting sand type structure comprises drag box, the cope engaging with drag box sealing, be located at the cope die cavity corresponding with drag box interface and described cam box structure, described casting sand type structure also comprises is located at many ingates that are connected with die cavity top in cope, be located at the cross gate being connected with ingate top in cope, be located in cope and be connected with cross gate for pouring into the sprue of molten iron.
Optimally, described ingate is evenly distributed in cope.
Further, described ingate is earthenware.
Further, described sprue does not face ingate.
Because technique scheme is used, the utility model compared with prior art has following advantages: the utility model cam box casting sand type structure, by being communicated with many ingates between cross gate and die cavity, make molten iron enter die cavity with rain type, the thermograde of molten iron is even, exhaust is smooth and easy, basic pore-free in the foundry goods of making.
Accompanying drawing explanation
Accompanying drawing 2 is the utility model cam box casting sand type structure cutaway view
Wherein: 1, cam box; 11, substrate; 12, tank wall; 13, fixing hole; 14, fixing hole; 2, cope; 3, drag box; 4, die cavity; 5, ingate; 6, cross gate; 7, sprue.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment is elaborated:
Cam box casting sand type structure as shown in Figure 2, for casting above-mentioned cam box 1, comprises cope 2, drag box 3, die cavity 4, ingate 5, cross gate 6, sprue 7.Wherein cope 2 engages with drag box 3 sealings, and in interface, is formed at the corresponding die cavity 4 of cam box 1 structure; Ingate 5 has many, be located in cope 2 and be connected with die cavity 4 tops, for introducing molten iron to die cavity 4 rain types, because foundry goods substrate 11 place's walls are thin, introduce herein ingate 5 water inlets, be conducive to reduce distributing of molten iron heat, make molten iron temperature gradient even, slow down solidifying of molten iron, the air of being convenient in molten iron and die cavity 4 sees through the gap discharge between die cavity 4 sand grains, and exhaust is smooth and easy.Cross gate 6 is also located in cope 2 with sprue, and cross gate 6 is connected with institute's ingate 5 tops, and 7 of sprues are connected with cross gate 6, for the molten iron of perfusion is evenly introduced to ingate 5.
In the present embodiment, ingate 5 adopts earthenware, can improve the surface quality of ingate 5, reduces the impact of molten iron to die cavity 4, reduces the sand hole defect of foundry goods.Ingate 5 is evenly distributed in cope 2, and sprue 7 is located at ingate 5 peripheries, does not face ingate 5, to change the flow direction of molten iron, reduces flow velocity, reduces the impact of molten iron to die cavity 4, is conducive to improve the product quality of foundry goods.
Above-described embodiment is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and implement according to this; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
