The structural elements to be considered in the Armchair Mould

  •   What should be paid attention to in the design process of Armchair Mould

      Armchair Mould design and manufacture are closely related to plastic processing. The success or failure of plastic furniture mold processing depends to a large extent on the design effect of the mold and the quality of mold manufacturing, and the design of Armchair Mould is based on the correct plastic product design.

      The structural elements to be considered in the Armchair Mould design are:

      The parting surface is the contact surface where the concave mold and the convex mold cooperate with each other when the mold is closed. The selection of its location and form is affected by factors such as product shape and appearance, wall thickness, molding method, post-processing technology, mold type and structure, demolding method, and molding machine structure.

      Structural parts, namely sliders, inclined tops, straight top blocks, etc. of complex molds. The design of structural parts is very critical, related to mold life, processing cycle, cost, product quality, etc. Therefore, designing the core structure of complex molds requires designers to have the higher comprehensive ability, and strive to be simpler, more durable, and more economical. the design of.

      The precision of the mold, that is, avoiding paper jams, precise positioning, guide posts, positioning pins, etc. The positioning system is related to the appearance quality, mold quality, and lifespan of the product. According to different mold structures, choose different positioning methods. The positioning accuracy control mainly depends on processing. The internal mold positioning is mainly considered by the designer to design a more reasonable and easier-to-adjust positioning method.

      The pouring system, that is, the feed channel from the injection molding machine nozzle to the cavity, includes the main runner, runner, gate, and cold material. In particular, the selection of the gate position should be conducive to the molten plastic filling the cavity in a good flow state. The solid runner and gate cold material attached to the product are easily ejected from the mold and taken out when the mold is opened. Except for road models).

      Plastic shrinkage and various factors that affect product dimensional accuracy, such as mold manufacturing and assembly errors, mold wear, etc. In addition, when designing compression molds and injection molds, the matching of process and structural parameters of the molding machine should also be considered. Computer-aided design technology has been widely used in plastic mold design.
