What are the golden rules to design an automobile injection mold?
There will be a close correlation between the development planning and manufacturing of automobile injection molds and plastic processing. The success and failure of plastic processing, to a large extent, depend on the mold planning effect and mold manufacturing quality, while the plastic mold planning is based on the correct plastic product planning. What structures should be considered in the planning of plastic molds? Let’s understand the following: parting surface: the contact surface between the cavity and the mold base when the mold is closed. The selection of its position and method is harmed by such factors as product posture and shape, wall thickness, forming method, post manufacturing process, mold type and structure, mold drawing method and forming machine structure.
Automobile injection mold structural parts: guide sliders, inclined guide pillars, straight jacking blocks, etc. of miscellaneous molds. The planning of automobile injection mold structural parts is very important, which is related to the service life of the mold, production and processing cycle time, cost, product quality, etc. Therefore, the planning of complex mold key structures has high rules for the planners’ inductive ability, and they try their best to pursue a better, simpler, more durable, more economic development plan. Mold precision: i.e., avoiding jamming, precise positioning, locating pin, circlip, etc. Mobile phone positioning system is related to product appearance quality, mold quality and service life. According to different mold planning, different precision positioning methods are selected for automobile injection molds. The key to precision level operation is production and processing. The core mold precision positioning is mainly considered by planners to plan more useful and easy to adjust precision positioning methods.
Gating system of automobile injection mold: the safe feeding channel from the plastic machine nozzle to the center of the female mold, including the sprue, separation channel, rubber inlet and cold material cavity. In particular, the selection of the rubber inlet should be conducive to filling the mold with molten plastic under the condition of fluidity, and the solid flow passage attached to the product and the cold material at the rubber inlet should be easy to eject from the mold and be eliminated.
The plastic shrinkage of automobile injection mold and various factors that endanger the product dimension accuracy, such as mold manufacturing and device errors, mold damage, etc. In addition, when planning the die and injection mold, the matching of the main parameters of the processing technology and structure of the forming machine should also be considered. The technology of auxiliary planning has been widely used in plastic mold planning. In addition, in the process of planning the plastic mold, the standard parts of the mold should also be taken into account, so that the full set of molds can achieve the effect, thus promoting the smooth development of the plastic mold in the injection mold processing stage.
