Abstract
The utility model discloses a prevent psammitolite expansion deformation's sand mould structure, including several cylinder body psammitolite, the main part psammitolite has the oil duct core, and the intercommunication increases psammitolite intensity between the adjacent oil duct core. The utility model has the advantages that improve the support intensity of psammitolite, the position and the main part core of oil duct core intercommunication form the cooperation, can prevent oil duct core core floatation, fracture under high temperature iron liquid.
Description
Technical field
This utility model relates to casting sand type field, particularly belongs to prevent the sand mould structure of core dilatancy.
Background technology
In prior art, cylinder casting sand mold forms the oil duct core of cylinder body back oil road structure, without connection between oil duct core.This structural disadvantages is, oil duct core is unsettled with between main body sand core after putting into die cavity, nothing coordinates, under high temperature iron liquid effect, and the easy core floatation of oil duct core, fracture.
Utility model content
The purpose of this utility model is available to a kind of sand mould structure preventing core dilatancy, and the advantage of this structure is to improve the support strength of core, and the position of oil duct core connection is formed with main core and coordinates, and can prevent oil duct core core floatation, fracture under high temperature iron liquid.
The technical solution of the utility model is as follows:
Preventing the sand mould structure of core dilatancy, include several main body sand core, cylinder body core has oil duct core, and between adjacent oil duct core, connection increases sand core strength.
The reinforcement core of described oil duct core weakness is formed with main body sand core and coordinates.
This utility model forms the oil duct core of cylinder body back oil road structure, oil duct cored structure weakness increases connection, the advantage of this structure is to improve the support strength of core, and the position of oil duct core connection is formed with main core and coordinates, and can prevent oil duct core core floatation, fracture under high temperature iron liquid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is three-dimensional view of the present utility model.
Detailed description of the invention
Seeing accompanying drawing, prevent the sand mould structure of core dilatancy, include several main body sand core 1, be communicated with reinforcement core 3 between adjacent oil duct core 2, the reinforcement core 3 of oil duct core 2 weakness is formed with main body sand core 1 and coordinates.
Claims (2)
1. preventing the sand mould structure of core dilatancy, it is characterised in that include several main body sand core, cylinder body core has oil duct core, and between adjacent oil duct core, connection increases sand core strength.
The sand mould structure preventing core dilatancy the most according to claim 1, it is characterised in that the reinforcement core of described oil duct core weakness is formed with main body sand core and coordinates.
