Engine exhaust pipe core pulling mechanism

Abstract

The invention discloses a core-pulling mechanism for an engine exhaust pipe, comprising an upper template, a lower template, a mold foot, a product, a thimble plate and a mold core for forming a product, the upper template is located on the upper surface of the lower template, and the The lower template is located between the upper template and the die foot, the ejector plate is slidingly fitted between the die foot and the lower template, and the mold core includes a first mold core for forming the lower end of the product and a mold core for forming The second mold core in the upper end of the product, the first mold core corresponds to the linear core pulling of a small part of the product, the second mold core corresponds to the arc core pulling of most of the product, and the upper surface of the lower template is along the The width direction of the lower template is provided with a first opening groove, and the upper surface of the lower template is provided with a second opening groove along the length direction of the lower template, and one end of the second opening groove communicates with the first opening groove. The present invention provides a The core-pulling mechanism of the engine exhaust pipe is convenient and easy to pull the core.

Description

technical field [0001] The invention relates to the field of molds, in particular to a core-pulling mechanism for an engine exhaust pipe. Background technique [0002] With the development of science and technology, automobiles have gradually become a common means of transportation for people. The engine exhaust pipe is one of the components of the automobile. The material of the engine exhaust pipe is soft rubber, and the engine exhaust pipe is formed by a mold. The shape of the engine exhaust pipe channel is arc-shaped. When forming, the engine exhaust pipe needs to be core-pulled by a core-pulling mechanism. According to the prior art, the engine exhaust pipe is core-pulled by using an ordinary arc core-pulling mechanism. , it is inconvenient to pull the core, and it is difficult to pull the core. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the above defects of the prior art, and to provide an engine exha...
