Abstract
The utility model discloses a molding sand core bar for manufacturing a rolling sleeve. The molding sand core bar consists of a plurality of main frames (1), which are connected integrally in the middle, and is characterized in that: the two ends of a plurality of main frames (1) are connected with a plurality of branch frames (2) towards both sides of the main frames, so that the core bar is radially forky with a plurality of heads. The molding sand of the utility model is difficult to scatter.
Description
Technical field
The utility model relates to a kind of core arbor, exactly is a kind of core arbor that roll sleeve is used of making.
Background technology
Roll sleeve is a hollow cylindrical, and roll sleeve is that molding sand forms roll sleeve shape space in mold, again molten iron is injected in roll sleeve shape space, removes molding sand after the cooling and promptly gets roll sleeve.Molding sand is linked to each other with the bottom core print seat by the top core and constitutes jointly.Because the volume of sand mold is big, for preventing to be scattered after the sand mold moulding, inside at molding sand is provided with arbor, arbor commonly used is connected as a single entity at mid point by some main bones and constitutes, and owing to the attached effect of arbor, has increased the intensity of molding sand, but existing arbor only is made of several main bones, the attached effect of arbor is not fairly obvious, and the intensity of molding sand is still not enough, causes molding sand the situation of being scattered still to occur.
The utility model content
The purpose of this utility model is exactly to solve that existing to make the molding sand arbor that roll sleeve uses not obvious to the attached effect of molding sand, makes molding sand the problem of being scattered still occur.
The technical solution adopted in the utility model is: make the molding sand arbor that roll sleeve is used, it is connected as a single entity at mid point by some main bones and constitutes, the two ends that it is characterized in that described some main bones are connected with several fulcra to main bone two side directions, make arbor be radiation bull forked.
Adopt technique scheme,, arbor and molding sand and contact area are increased greatly, thereby reach the attached power that increases arbor and molding sand greatly, increased the intensity of molding sand, make molding sand be difficult for being scattered because main bone two side directions are connected with several fulcra.
The utility model beneficial effect is: connect fulcra because the utility model adopts at the two ends of main bone, increased the contact area with molding sand, increased attached power, so the utility model makes molding sand be difficult for being scattered.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is made the molding sand arbor that roll sleeve is used, and as shown in Figure 1, it is connected as a single entity at the middle part by some main bones 1 and constitutes, and the two ends of described some main bones 1 are connected with several fulcra 2 to main bone two side directions, make arbor be radiation bull forked.
Claims (1)
1. make the molding sand arbor that roll sleeve is used, it is characterized in that by some main bones [1] formations that be connected as a single entity at the middle part two ends of described some main bones [1] are connected with several fulcra [2] to main bone two side directions, arbor is radiates the bull forked.
