Embodiment 1

[0022] Attached below Figure 1-3 To further describe the present invention, a method for preparing an automobile engine balancer housing, the material of the automobile engine balancer housing is YZAlSi 9 Cu 3 Aluminum alloy, YZAlSi 9 Cu 3 The aluminum alloy is die-cast in a cold chamber die-casting machine. The cold chamber die-casting machine includes an injection punch 1, a fast injection accumulator 3 and a booster accumulator 4. After the slow injection, the fast injection and Pressurized injection, the rapid injection accumulator 3 and the pressurized accumulator 4 of the cold chamber die-casting machine pressurize the injection punch 1 at the same time until YZAlSi 9 Cu 3 The aluminum alloy liquid fills the mold cavity.

[0023] YZAlSi 9 Cu 3 The die-casting process of aluminum alloy in the cold chamber die-casting machine is controlled by a PLC controller (the prior art), and the fast-injection accumulator 3 and the pressurized accumulator 4 are respectively co...

Abstract

The invention belongs to the technical field of die-casting processes, and particularly relates to a preparation method of an automobile engine balancer shell, the automobile engine balancer shell is made of YZAlSi9Cu3 aluminum alloy, the YZAlSi9Cu3 aluminum alloy is subjected to die casting in a cold chamber die-casting machine, the cold chamber die-casting machine comprises an injection punch, a rapid injection energy accumulator and a pressurization energy accumulator, and after slow injection, the rapid injection energy accumulator and the pressurization energy accumulator are subjected to die casting; fast injection and pressurized injection are started at the same time, and a fast injection energy accumulator and a pressurized energy accumulator of the cold chamber die casting machine pressurize an injection punch at the same time till a die cavity is filled with the YZAlSi9Cu3 aluminum alloy liquid; according to the preparation method of the automobile engine balancer shell, the current situation that in the prior art, injection of a cold chamber die casting machine is divided into three stages (low-speed injection, rapid injection and pressurized injection) is changed, cooperation of rapid injection and pressurized injection is achieved, the injection force of an injection punch is increased, and the service life of the injection punch is prolonged. And the qualification rate of the die-cast automobile engine balancer shell is greatly improved.

Description

technical field [0001] The patent of the invention belongs to the technical field of die-casting technology, and specifically relates to a method for preparing an automobile engine balancer housing. Background technique [0002] Automobile generator balancer, which is mainly used for diesel automobile engines, is installed on the upper part of the oil pan and meshes with the main shaft gear of the engine. The vibration generated during forward rotation, therefore, requires high mechanical performance of the balancer shell, and the load-bearing parts must not have internal and external defects, and the weight is light. [0003] In this regard, in actual work, YZAlSi is selected 9 Cu 3 The material is selected as the housing of the automobile engine balancer. The production process of high pressure casting is selected, the test plan is designed, step by step, step by step, and the size of the shell is designed according to the volume of the automobile engine bottom shell t...
