Abstract
The utility model relates to a device for positioning and mould assembling in the sand mould casting, in particular to a mould assembling device for the sand mould casting. The device is characterized in that the device comprises a barrel-formed mould assembling sleeve (1), the mould assembling sleeve (1) is formed by two semi-mould assembling sleeves with the same shape, and the device also comprises a positioning cone (2) which is arranged in the mould assembling sleeve (1) and of which the outer surface is matched with the inner surface of the mould assembling sleeve (1). When the die is designed, the proper tolerances of the metal mould assembling sleeve and the positioning cone are selected for matching, thereby ensuring that the metal mould assembling sleeve does not grip the positioning cone when the device is used. Firstly, the device is matched with a positioning cone of a mould plate for casting so as to make the sand mould accurately and reliably positioned; and secondly, the metal positioning cone is put inside in the mould assembling so as to ensure that the cast does not miss the mould and is high in dimensional accuracy. In the production and use processes, the device can effectively overcome the defect of the cast missing the mould, and the operation is simple and convenient.
Description
Technical field
The utility model relates to a kind of instrument that is used to locate mould assembling in sand casting, especially mould assembling device for sand casting.
Background technology
The following dual mode of the general employing in traditional mould assembling location of existing sand casting:
1, fixing mould assembling awl on the plate is produced the locating hole that mould assembling is used on sand mold, inserts sand system closing pin and carry out the sand mold mould assembling and operate in the mould assembling process.This mould assembling method is simple, easy operating, but since locating hole, closing pin all make of sand mold, in operating process because of the rocking of sand mold, positive error etc. all caused especially easily the wearing and tearing of locating hole, closing pin, cause the sand mold dislocation, finally form the defective of foundry goods mould shift.This mould assembling mode is fatal often for the caused defective of the high foundry goods of dimensional requirement, makes the percent defective of foundry goods higher.
2, on sandbox, template, make latch structure, in moulding, mould assembling process, use latch.This method dimensional accuracy height, but operating process is numerous and diverse, difficulty and higher to the size and the structural requirement of sandbox, only is suitable for the high production line operation of mechanization degree.
The utility model content
The purpose of this utility model provides a kind of mould assembling device for sand casting, and its accurate positioning, reliable can guarantee not mould shift of foundry goods and dimensional accuracy height.
Come the utility model is described in further detail below in conjunction with accompanying drawing:
A kind of mould assembling device for sand casting, its special feature are, comprise the mould assembling cover of tubbiness, and this mould assembling cover is made up of two identical housing-cases that narrow of shape, also comprise being installed in the locating cone that its outer surface cooperates with mould assembling cover inner surface in this mould assembling cover.
Wherein the locating cone interlude is cylindric, and two ends are hemispherical or coniform.
Further, wherein mould assembling cover and locating cone are metal material.
The utility model is selected suitable tolerance fit for use to metal mould assembling cover and locating cone when design, guarantee metal mould assembling cover and not interlock of locating cone in the use.The locating cone of at first casting in the using stencil cooperates, and makes accurate positioning in the sand mold, reliable, puts into the metal locating cone then when mould assembling, guarantees not mould shift of foundry goods and dimensional accuracy height.In the production use, this kind device can effectively reduce foundry goods mould shift generation of defects and simple, convenient.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 3, the utility model discloses a kind of metal mould assembling easy to use cover 1 and locating cone 2, during design, involutory housing-case 1 and locating cone 2 are selected suitable tolerance fit for use, guarantee mould assembling cover 1 and locating cone 2 not interlocks in the use.When mould assembling, put into locating cone 2, thereby by locating cone 2 and cooperating of mould assembling cover 1 guaranteeing not mould shift of foundry goods and precision height.
Make because the mould closer in the last nowel all is a metal, in the mould assembling operating process, produce hardly locating hole, closing pin wearing and tearing, move, make mould assembling accurately, not mould shift, and operating process is simple and reliable.
Claims (3)
1, a kind of mould assembling device for sand casting, it is characterized in that: the mould assembling cover (1) that comprises tubbiness, this mould assembling cover (1) is made up of two identical housing-cases that narrow of shape, also comprises being installed in the locating cone (2) that its outer surface cooperates with mould assembling cover (1) inner surface in this mould assembling cover (1).
2, mould assembling device for sand casting as claimed in claim 1 is characterized in that: wherein locating cone (2) interlude is cylindric, and two ends are hemispherical or coniform.
3, mould assembling device for sand casting as claimed in claim 1 or 2 is characterized in that: wherein mould assembling cover (1) and locating cone (2) are metal material.
