Lost foam gluing mould

Abstract

The invention belongs to auxiliary tools in the technical field of engine casting, and particularly relates to a lost foam gluing mould. The lost foam gluing mould comprises an upper mould plate and a lower mould plate which are arranged on a rack, and a die used for gluing the bottom of an upper half body of a lost foam; the upper mould plate and the lower mould plate are arranged in the vertical direction in an openable mode; the die is arranged in the vertical direction in a reciprocating motion mode; a glue pool used for containing glue is arranged below the die; when the die moves downwards, the upper surface of the die can sink into the glue pool; the upper mould plate is arranged in the horizontal direction in a reciprocating motion mode so that the upper mould plate can move to the position above the die or the lower mould plate alternately; and when the upper mould plate moves to the position above the die and the die moves upwards, glue on the upper surface of the die can be printed on the bottom of the upper half body of the lost foam. The lost foam is automatically glued through the die, the upper body and the lower body of the lost foam are pressed to be glued into a whole through the upper mould plate and the lower mould plate, and the gluing precision and efficiency of the lost foam are greatly improved.

Description

technical field [0001] The invention belongs to auxiliary tooling in the technical field of engine casting, and in particular relates to a lost foam glued mold. Background technique [0002] The lost foam casting process is to use paraffin or foam models similar in size and shape to the castings to bond and combine to form a model cluster. After brushing refractory paint and drying, it is buried in dry quartz sand for vibration molding, and poured under negative pressure to make the model gas. It is a new casting method in which liquid metal occupies the position of the model, solidifies and cools to form a casting. The lost foam casting process has the advantages of high precision, flexible design, and no sand core in traditional casting. However, in order to produce high-quality castings, early model making is particularly important. For many parts with complex structures, especially parts with complex inner cavities like the engine block, the model making must use split ...

Problems solved by technology

In the prior art, manual glue bonding is often used for bonding. This method is difficult to ensure accurate positioning between the split structures, and is prone to defects such as uneven glue application, which seriously affects the molding quality of castings.
