Production process of high-density engineering machinery balancing weight

Abstract

The invention discloses a production process of a high-density engineering machinery balancing weight. The engineering machinery balancing weight is composed of a movable mold base plate, a movable mold plate, a fixed mold base plate, a fixed mold plate, a mold cavity and a plastic part. The plastic part is provided with two pressing blocks which are independently arranged, and the pressing blocks are arranged in the two axial directions of the plastic part. In the manufacturing process of the balancing weight, weight balancing can be carried out according to the actually-used structure, balance weights of different structures can be achieved by increasing and decreasing the pressing blocks, and different balancing weight molds do not need to be manufactured according to different structures; and furthermore, a melting cavity is formed in the plastic part of the balancing weight, and in the later use process, if the micro-balance weight ratio needs to be adjusted, only balance weight solutions with different weights need to be injected into the melting cavity, and the good balance weight effect can be achieved.

Description

technical field [0001] The invention relates to a production process of high-density construction machinery counterweights, and specifically relates to the technical field of die-casting industry. Background technique [0002] Construction machinery counterweights, as the name implies, are mainly used to reduce and buffer the vibration of passengers and some precision mechanisms during bumps, so as to ensure the comfort of passengers and drivers and protect the service life of precision mechanisms. The shock counterweight is mainly used to reduce the quality gap between the various components of the construction machinery to achieve the purpose of reducing vibration. The production of shock-absorbing counterweights for construction machinery is generally formed by pouring. The pouring is mainly to pour high-temperature molten cast iron into the mold, and then after it cools naturally, open the mold and take out the casting to obtain construction machinery. Class counterweig...

Problems solved by technology

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a production process of high-density construction machinery counterweights to solve the construction machinery requirements for construction machinery with different volumes and sizes proposed in the background technology. The weight of the counterweight has different requirements, so the weight of the commonly used engineering machinery counterweight needs to be designed according to different molds for different volumes and sizes of vehicles, resulting in greater waste and increased production costs.
