One-mold multi-cavity multi-purpose sieve plate pouring mold system

Abstract

The utility model relates to a multi-cavity and multi-purpose sieve plate pouring mold system, which belongs to the technical field of sieve plate pouring molds. A mold skeleton is placed inside the mold body, and a colloid stirring mechanism is provided above the mold skeleton; the mold body includes a motherboard (1) and a positioning frame, the motherboard (1) is a bottom plate set at the bottom of the positioning frame, and the upper end surface of the motherboard (1) A positioning frame is provided, and a plurality of installation grooves for placing the mold skeleton are formed on the motherboard (1) through the positioning frame, and each installation groove is provided with a clamping device, and the periphery of the installation groove is provided with a compression positioning mechanism. The present invention has simple overall structure, convenient maintenance, low mold cost and convenient assembly and disassembly. The casting process of one mold with multiple cavities can be realized, which greatly improves the production efficiency.

Description

technical field [0001] A multi-cavity multi-purpose sieve plate casting mould system belongs to the technical field of sieve plate casting moulds. Background technique [0002] Polyurethane edging sieve plate and blind plate products belong to the wearing parts in the fields of coal washing and de-intermediation. In order to increase the wear resistance, strength and service life of the product, the sieve plate and blind plate are now using the process of polyurethane casting and edging. The quality of the mold and the pouring efficiency are very high. The existing sieve plate casting molds are all single-mode and single-cavity, with manual mixing and pouring, and the production efficiency is extremely low. Due to poor exhaust performance, the product is trapped in air, which leads to the reduction of the overall strength and wear resistance of the product. Seriously due to uneven stirring, uneven heating and other factors, degumming or direct fracture may occur. For this, ...

AI Technical Summary

Problems solved by technology

The existing casting molds for sieve plates are all single-mode and single-cavity, manual mixing and pouring, the production efficiency is extremely low, and the type of products poured in the same pair of molds is single, resulting in a variety of mold types that are not universal, and it is difficult to demould. Due to poor exhaust performance, the product is trapped, which leads to a decrease in the overall strength and wear resistance of the product. Seriously, it will be degummed or directly broken due to factors such as uneven stirring and uneven heating. Suppliers generally use opaque color paste for this. Mixing is used to cover up the air bubbles of the product from the appearance, which will lead to a low service life of the product, which will lead to faster replacement of sieve plates and other products in the coal washing plant, and even lead to shutdown of production in severe cases
