Abstract

The utility model discloses a combined type core box for sand core molding. The combined type core box comprises a base, wherein a U-shaped guide sliding groove is fixedly formed in the upper end surface of the base; a core plate is slidably arranged in the guide sliding groove, and is formed by splicing a plurality of assembly plates; and semi-strip-shaped grooves with different lengths are formed in opposite surfaces of the assembly plates at intervals. The combined type core box is reasonable in structural design; the core plate is formed by splicing the assembly plates; and sand cores with different lengths can be gathered in a core box and is manufactured and molded, so that the processing efficiency is improved.

Description

A kind of core moulding combined type core box

Technical field:

The utility model relates to the high-abrasive material process technology, relates in particular to a kind of core moulding combined type core box.

Background technology:

For the manufacture of the material of core, generally mixed according to a certain percentage by casting model powder, moulding sand binder and the auxilliary Modeling Material such as thing that adds in the Foundry Production.Core is most of in casting mold to be surrounded by the liquid metal of high temperature, and the size of support localization part is generally less, so core sand also requires to have higher intensity, gas permeability, deformability and collapsibility except the performance that should have general molding sand.

In the wallboard process, the core of different length is made with different core boxes usually, need make moulding by a plurality of cores for the manufacturing of one group of core, and processing capacity is big, makes trouble, and causes working (machining) efficiency low.

The utility model content:

In order to remedy the prior art problem, the purpose of this utility model provides a kind of core moulding combined type core box, and reasonable in design is made moulding with the core unification of one group of different length by a core box, has improved working (machining) efficiency.

The technical solution of the utility model is as follows:

Core moulding combined type core box, comprise base, it is characterized in that: fixedly there is the guide chute of U-shaped described base upper surface, be slidingly fitted with central layer in the guide chute, central layer is made of some assembled plate assembly units, has half bar-shaped trough of different length on the corresponding face of some assembled plate at interval.

Described core moulding combined type core box, its feature is being: after described some assembled plate are assembled into central layer, half bar-shaped trough assembly unit constitutes six groups of bar holes, six groups of bar holes constitute to blind end parallel distribution successively along the openend of guide chute, and wherein second from the bottom group of bar hole is made of the bar hole of three sections different lengths.

Described core moulding combined type core box, its feature is being: described base, central layer all adopt wood materials to make.

The utility model has the advantages that:

The utility model reasonable in design, by some assembled plate assembly units are constituted central layer, the core that can cross different length is unified in a core box manufacturing moulding, has improved working (machining) efficiency.

Description of drawings:

Fig. 1 is structural representation of the present utility model.

The specific embodiment:

Referring to Fig. 1:

Core moulding combined type core box, comprise base 1, fixedly there is the guide chute 2 of U-shaped base 1 upper surface, is slidingly fitted with central layer in the guide chute 2, central layer is made of 3 assembly units of some assembled plate, has half bar-shaped trough 4 of different length on the corresponding face of some assembled plate 3 at interval.

After some assembled plate 3 were assembled into central layer, 4 assembly units of half bar-shaped trough constituted six groups of bar holes, and six groups of bar holes constitute to blind end parallel distribution successively along the openend of guide chute, and wherein second from the bottom group of bar hole 5 is made of the bar hole of three sections different lengths.

Base 1, central layer all adopt wood materials to make.
