Abstract

The invention discloses a method for preventing sand accumulation in a sand hopper of a core shooter. The method for preventing sand accumulation in the sand hopper of the core shooter includes the following steps that firstly, a PVC board is tailored to be in the shape matched with that of the inner wall of the sand hopper; secondly, the tailored PVC board is paved on the sand hopper so that the PVC board is tightly attached to the inner wall of the sand hopper; and finally, the PVC board and the inner wall of the sand hopper are fixed together. By means of the method for preventing sand accumulation in the sand hopper of the core shooter, as the PVC board is paved on the inner wall of the sand hopper, sand mixed with resin can be well prevented from being attached to the inner wall of the sand hopper, accumulation of hard sand on the inner wall of the sand hopper is completely avoided, the hard sand can be well prevented from causing the quality problem, and the labor intensity of machine cleaning by a person on the post is reduced.

Description

Prevent core shooter sand hopper from amassing the method for sand

Technical field

The present invention relates to core shooter field, particularly a kind of method preventing core shooter sand hopper from amassing sand.

Background technology

At present, at cold-box core blower puddle mixer sand hopper and the core shooter sand hopper of casting use, because bucket inwall directly contacts with the sand being mixed with resin, sand sticks to sand hopper inwall.General is all that an order of classes or grades at school just clears up a sand hopper in 10 hours, and the sand that sand hopper inwall amasss is not only hard but also thick.Hard sand penetrates cylinder if fall into core shooter, can directly affect core quality.The hard sand sticking to sand hopper brings difficulty to clear, and post librarian use iron hammer strikes, and pneumatic pick is beaten and could be cleared up long-pending sand, and cleaning once amasss sand at least 40 minutes.

The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.

Summary of the invention

A kind of core shooter sand hopper that prevents of simple and reasonable steps is the object of the present invention is to provide to amass the method for sand, this prevents core shooter sand hopper from amassing the method for sand by laying PVC board at sand hopper inwall, can well prevent the sand being mixed with resin from sticking to sand hopper inwall, thus stop sand hopper inwall and amass hard sand, quality problems well avoiding long-pending hard sand to cause and reduce post personnel's clear labour intensity.

For achieving the above object, the invention provides a kind of method preventing core shooter sand hopper from amassing sand, comprise the following steps: first, PVC board is cut into the shape with sand hopper inwall adaptation; Then, the PVC board of cutting out shaping is laid on sand hopper, PVC board and sand hopper inwall are close to; Finally, PVC board and sand hopper inwall are fixed together.

Preferably, in technique scheme, PVC board is cut into triangle.

Preferably, in technique scheme, PVC board and sand hopper inwall are fixed together by rivet.

Compared with prior art, the present invention has following beneficial effect: this prevents core shooter sand hopper from amassing the method for sand by laying PVC board at sand hopper inwall, can well prevent the sand being mixed with resin from sticking to sand hopper inwall, thus stop sand hopper inwall and amass hard sand, quality problems well avoiding long-pending hard sand to cause and reduce post personnel's clear labour intensity.

Accompanying drawing explanation

Fig. 1 is the flow chart preventing core shooter sand hopper from amassing the method for sand of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.

Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.

As shown in Figure 1, amass sand thick according to the method preventing core shooter sand hopper from amassing sand of the specific embodiment of the invention for cold-box core blower sand hopper, falling hard sand affects the problem such as core quality and clear difficulty.Repeatedly attempt through us, if find to lay wear-resisting PVC smooth plate to sand hopper inwall, can well avoid the sand being mixed with resin to stick on sand hopper.This prevents core shooter sand hopper from amassing comprising the following steps of the method for sand:

First, PVC board is cut into triangle;

The sheet material that PVC board is take PVC as cross section that raw material is made is honeycomb eyed structure is a kind of vacuum forming film.Top layer for all kinds of panel is packed, so the decorating film that is otherwise known as, attached glued membrane, is applied to all conglomeraties such as building materials, packaging, medicine.Wherein the proportion that accounts for of building material industry is maximum, and being 60%, is secondly packaging industry, also has some other industries applied among a small circle.

PVC board is cut into triangle and is convenient to PVC board and is laid on sand hopper, make PVC board and sand hopper inwall without any gap.

Then, the PVC board of cutting out shaping is laid on sand hopper, make PVC board and sand hopper inwall be close to without any gap;

PVC board and sand hopper inwall be close to without any gap be that sticky the entering between PVC board and sand hopper inwall of sand in order to prevent from being mixed with resin is deposited.

Finally, rivet is used PVC board and sand hopper inwall to be fixed together.

From buying wear-resisting smooth PVC board on the market, according to the actual size of sand hopper, be cut into triangle.Drilling sand hopper is laid on the PVC board of cutting out shaping on sand hopper, PVC board and sand hopper inwall without any gap, re-use rivet fixing PVC plate, cost of manufacture is low, and method is simple and reliable.

This advantage preventing core shooter sand hopper from amassing the method for sand comprises: 1, reduce sand hopper and amass sand, reduce post employee labour.2, the low method of cost of manufacture is simple and reliable.

To sum up, this prevents core shooter sand hopper from amassing the method for sand by laying PVC board at sand hopper inwall, well can prevent the sand being mixed with resin from sticking to sand hopper inwall, thus stop sand hopper inwall and amass hard sand, quality problems well avoiding long-pending hard sand to cause and reduce post personnel's clear labour intensity.

The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
