Manufacturing device and method of a bearing cap core

Abstract

The invention discloses a bearing cap core production unit and production method. The production unit comprises a top core plate, a guide plate, a guide rod, a top core rod, a crank link mechanism, a core box and an electrical control unit. The guide rod passes through the guide plate and is then attached to the top core plate; the top core rod is arranged on the guide plate and is able to move towards the top core plate along with the guide plate under the guiding role of the guide rod; the crank link mechanism is arranged on the guide plate, and can drive the guide plate to move along the guide direction of the guide rod; the core box is arranged on the top core plate; the electric control unit can control the working temperature of the core box; and the top core holes corresponding to the top core rod are arranged on the top core plate and the core box. The unit and method of the invention, based on the electrical control systems and crank link mechanism, realize efficient production of the core; the core combines functions of heating and convenient acquisition; and the invention has the advantages of high production efficiency bearing cap core, easy operation and high quality core production.

Description

technical field [0001] The invention relates to the technical field of core making, in particular to a manufacturing device and method for a bearing cap product core. Background technique [0002] In the prior art, the production of bearing cap product cores is realized by means of a core box structure. The core box has an upper core box and a lower core box structure. There is a chute on the upper core box, and the upper and lower core boxes are closely spaced during core making. Fitting, the upper and lower core boxes are reliably positioned by two positioning pins. When making cores by hand, the upper and lower core boxes are tightly pressed, and a certain degree of compactness is ensured to make cores between them. When the finished core is opened and the core is taken out, the prior art always adopts the method of sand making, which makes it very inconvenient to take out the core after the core is made, and the coring process can easily lead to deformation of the core,...

AI Technical Summary

Problems solved by technology

When the core is made and the core is opened and the core is taken out, the method of sand making is used in the prior art, which makes it very inconvenient to take out the core after the core is made, and the coring process can easily cause the core to deform and fail to meet the quality requirements At the same time, because the core is made by manual oil sand, after the core is made, it must be baked in a special resistance furnace, so the finished core in the prior art has a long completion period, the production process is relatively complicated, and the cost is high
