Description

Sand core molding sand shooting mechanism

Technical Field

The utility model belongs to the technical field of the psammitolite production, concretely relates to psammitolite shaping is with penetrating sand mechanism.

Background

As shown in fig. 1 and 2, the sand core is provided with a sand core main body in an elbow structure and a core head sleeved at one end of the sand core main body, wherein the core head is in a tubular structure sleeved on the sand core main body, the lower end of the core head is bent towards one side to form a structure with an L-shaped longitudinal section, and the core head is in a blind pipe structure with a closed lower end; the sand core is provided with a sand shooting and blowing channel; the sand shooting and blowing channel comprises a plurality of sand shooting and blowing channels I communicated with the sand core main body and a sand shooting and blowing channel II sleeved on one end of the sand core main body, which is close to the core head; when sand shooting and air blowing are carried out, the core head is of a blind pipe structure, so that the problems of sand core scrapping caused by incomplete shooting and insufficient sand are easily caused during on-site core manufacturing.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model aims at providing a psammitolite shaping is with penetrating sand mechanism.

The utility model adopts the following technical scheme for accomplishing the above purpose:

a sand shooting mechanism for sand core molding is provided, wherein a sand core is provided with a sand core main body in an elbow structure and a core head sleeved at one end of the sand core main body; the core head is a tubular structure sleeved on the sand core main body, the lower end of the core head is bent towards one side to form a structure with an L-shaped longitudinal section, and the core head is a blind pipe structure with a closed lower end; the sand core is provided with a sand shooting and blowing channel; the sand shooting and blowing channel comprises a plurality of sand shooting and blowing channels I communicated with the sand core main body and a sand shooting and blowing channel II sleeved on one end of the sand core main body, which is close to the core head; a communicating air passage is arranged between the sand shooting and air blowing channel II and the upper end opening of the core head; a plug used for changing the blowing channel of the sand shooting blowing channel II and enabling the sand shooting blowing channel II to be communicated with the core head through a communicating air channel is further arranged in the sand shooting blowing channel II; and the blind end of the core print is provided with an exhaust insert communicated with the outside.

The utility model provides a pair of psammitolite shaping is with penetrating sand mechanism considers from the shaping principle of psammitolite, will penetrate sand blow the II seals of passageway, will penetrate sand blow passageway II and be linked together through interface channel and core to set up the exhaust at the cecum of core and insert, blow for penetrating sand and provide a passageway, guarantee to penetrate that sand exhausts unobstructed, avoid appearing penetrating the condition unrealistic, that sand is virtual, provide the yield of psammitolite.
