 Pre design review(mold products)
1. Mold material
2. Molded products
3. Molding machine selection
4. Basic structure of formwork base

 Important items in mold design(mold products)
1. Multi color injection combination
2. Sprue system
(1) The injection pressure is low.
(2) Rapid filling can increase production.
(3) It can be injected evenly and the product quality is good.
(4) Reduce waste and shorten injection time.

3. Forming equipment(mold products)
(1) The injection volume of each injection cylinder determines which cylinder is used for the same color.
(2) Position and stroke of striking rod.
(3) The configuration of water circuit, oil circuit and circuit on the rotating disc.
(4) The bearing weight of the rotating disc.

4. Mold base design: mold core configuration design(mold products)
First of all, considering that the male mold side of the mold must rotate 180 degrees, the mold kernel setting must be arranged in a cross and symmetrical manner, otherwise the mold cannot be closed and formed.
(1) Guide post: it has the function of guiding the male mold and the female mold. Concentricity must be maintained in multicolor mold.
(2) Return pin: because the mold must rotate, it is necessary to fix the ejector plate, and add a spring on the return pin to keep the ejector plate stable.
(3) Positioning block: ensure that the two die bases are not offset due to the gap of screws when they are fixed on the large fixed plate.
(4) Adjusting block (wear-resistant block): it is mainly used to adjust the Z coordinate value error of die height during die clamping.
(5) Ejection mechanism: the design of ejection mode is the same as that of general molds.
(6) Cooling circuit design: the cooling circuit design of mold I and mold II shall be the same as far as possible.
