One-mold multi-cavity multipurpose screen plate casting mold system

Abstract

The invention relates to a one-mold multi-cavity multipurpose screen plate casting mold system, and belongs to the technical field of screen plate casting molds. A mold framework is placed in a mold body; an adhesive stirring mechanism is arranged above the mold framework; the mold body comprises a motherboard (1) and a positioning frame; the motherboard (1) is arranged on a bottom plate on the bottom part of the positioning frame; the positioning frame is arranged on the upper end face of the motherboard (1); multiple installation grooves for placing the mold framework is formed on the motherboard (1) through the positioning frame; a clamping device is arranged in each installation groove; and a pressing and positioning mechanism is arranged on the periphery of each installation groove. The one-mold multi-cavity multipurpose screen plate casting mold system provided by the invention is simple in overall structure, convenient to maintain, low in mold cost, and convenient to assemble and disassemble. A one-mold multi-cavity casting process can be realized, so that the production efficiency is greatly improved.

Description

technical field [0001] 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. Background technique [0002] Polyurethane edge-wrapped sieve plate and blind plate products are vulnerable parts in the field 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 now adopt the process of polyurethane casting and edge wrapping, which has a great impact on casting The quality of the mold and the casting efficiency are very high. 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 p...

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
