Problems solved by technology

Due to the complex and long flow path of the existing laminated mold, the material injected from the main feed port needs to pass through the parting surface and be evenly distributed between the two layers of cavities, resulting in the problem of unbalanced pressure between the front and rear cavities
In addition, since the material is injected from the module on one side of the mold, there is a problem that the material is difficult to seal when the mold is opened

Abstract

A stack mold in the present invention, having a fixing module, a movable module and a middle module, the middle module being arranged between the fixing module and the movable module, and the movable module and the middle module moving towards a direction being close to the fixing module until a first mold cavity is formed by the middle module and the fixing module and a second mold cavity is formed by the movable module and the middle module; the stack mold also comprises an injection molding runner; a main body central axis of a main runner of the injection molding runner is arranged in a central plane, being vertical to a direction of a movement axis of the movable module, of the middle module. In the present invention, materials enter an injection molding runner through a middle module and do not have to penetrate through a mold joint, thereby enabling pressure of each mold cavity to be more balanced; and meanwhile, the problem of seal leakage of the materials during mold opening is avoided.

Description

technical field [0001] The invention relates to the field of injection molding equipment, in particular to a laminated mold. Background technique [0002] The mold of the traditional horizontal injection molding machine has only one cavity, and each time the mold is opened and closed, only one layer of products can be produced, and the production efficiency is low. For this reason, people design " laminated mold ", for example, CN203792627U, CN201346830Y all disclose laminated mold, and it comprises movable module, middle module, fixed module arranged in order from front to back in structure, and the difference between movable module and middle module The first layer of cavity is formed between the middle module and the fixed module, and the second layer of cavity is formed between the middle module and the fixed module. Usually, the general feed port of the mold is set on the fixed module, and the material is poured into each cavity through horizontal injection. Due to th...
