Injection mold of plastic manifold for intake system of mini-car engine

Abstract

The invention relates to an injection mold of a plastic manifold for an intake system of a mini-car engine. The injection mold of the plastic manifold for the intake system of the mini-car engine comprises a cavity and a core. The cavity is provided with guide posts, a manifold upper intake pipe opening inclined guide post, manifold lower exhaust pipe opening inclined guide blocks, a manifold upper side nut embedment inclined guide post, a manifold lower side nut embedment inclined guide post, a manifold lower front nut embedment inclined guide post, a manifold upper pipe clip inclined guide post, an upper core and a lower core. The core is provided with guide sleeves, a manifold upper intake pipe opening forming sliding block, a manifold lower exhaust opening forming sliding block, a manifold upper side nut embedment rod sliding block, a manifold lower side nut embedment rod sliding block, a manifold lower front nut embedment rod sliding block, a manifold upper pipe clip forming sliding block, an upper cavity and a lower cavity. According to the injection mold of the plastic manifold for the intake system of the mini-car engine, one oil cylinder can drive multiple sliding blocks, the structure that the sliding blocks drive the sliding blocks is also designed, the structure is relatively simple, and the manufacturing cost can be reduced; and meanwhile, one mold can produce the upper half portion and the lower half portion of a product at the same time, and therefore the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a molding die, in particular to a plastic manifold injection molding die for an engine intake system of a miniature car. Background technique [0002] With the development of the automobile industry, energy saving and environmental protection have become two major issues of the automobile industry. Functional plastics are constantly replacing metal materials due to their light weight, low manufacturing cost and excellent performance, making automobile engines achieve breakthroughs in light weight, energy saving, environmental protection and manufacturing costs. Engine valve chamber covers, intake manifolds, oil pans, etc. Shells, small gasoline engine camshafts, rocker arms, oil pumps, water pumps, gearbox covers, etc. are made of nylon materials. [0003] At present, the injection molding of plastic manifolds for automobile engine air intake systems needs to be completed through molding molds. The existing plastic manifold mo...

Problems solved by technology

However, the slider action of the existing forming mold is that one slider is directly driven by a corresponding oil cylinder, so that a set of molds needs to be equipped with multiple oil cylinders, which will make the structure complicated, and the mold with multiple sets of sliders Bigger, more expensive

[0005] 2. The existing molds are all part of a set of mold forming products, that is, a set of molds produces a part. If the product is divided into several parts, several sets of molds are required correspondingly. The production benefit is poor, the efficiency is low, and it takes up a lot of resources. , unable to realize the supporting production of products
