How to standardize injection molds in order to improve mold efficiency? From a professional point of view, to do a set of molds, you should pay attention to the following issues:
1. A mold blank smaller than 2020, a die pit is required between the a and b plates; a mold pit larger than 2020, all of which include a thimble.
2. The mold guide post guide sleeve should be processed to the exhaust groove to prevent the guide post guide sleeve from being pulled.
3. There must be no sharp corners on the mold and chamfering is required. Except where specified
4. The inner mold and mold parts must not be welded without consent.
5. The periphery of the mold product must be opened at the appropriate position. For the specifications of the exhaust groove, please refer to the mold design manual.
6. Avoid using a sander to grind the mold as much as possible. If it is necessary to use a sander, you must use oil stone to save light (especially the parting surface).
7. The surface treatment of the internal molding surface must be performed in accordance with the BOM or other officially notified technical requirements. The processing lines on the non-adhesive surface (line cutting, milling, CNC boring machine, spark machine) should also be polished with oil stone.
8. For all internal mold materials, the mold grade requirements must be purchased in accordance with the order or the technical requirements officially confirmed during the design review process. A proof of material must be provided, and if it is a hard mold, a heat treatment report must be provided. All relevant proofs.
9. The front and back inner molds of all molds, inserts, row positions, slant tops, straight tops (push blocks), shovel chickens, etc. need to machine a waist round pit on the bottom or side, and engrave the material name and hardness.
10. Important wearable parts such as row position, push block, shovel chicken, and pout must be nitrided and hardened.
11. The position must be positioned. The positioning methods include slingshot, wave bead, HASCO (DME) standard position clamp, etc., which need to be in accordance with the requirements of each project. The row needs to have a bead and a wear plate. For the beading and wear-resistant plates, wear-resistant hard materials must be used, and oil grooves are required.
12. The row guide column must be pressed tightly and cannot be rotated or loosened. The tail of the inclined guide column must be processed into a hemispherical or truncated cone shape to help ensure normal movement of the row. If there are two or more inclined guide columns in the same row position, the length, size and inclination of the inclined guide columns must be the same.
13. The sloping top seat must use hard wearing materials. The inclined top must be machined with oil grooves. The inclined top seat is generally hardened with 2510 or cr12 to hrc40-45 degrees. Because the inclined top seat is subjected to the impact load, it cannot be too hard or it will break and chamfer the c angle at all right angles. . A sloping top guide (bronze) is required. Do not weld.
14. The flow path and the glue position need to save the light #400-600.
15. The thimble, the cylinder, the thimble, the slanting top and the thimble should be engraved with the corresponding identification code for easy installation. If the thimble position is not horizontal on the product, the thimble seat needs to be made "D" or positioned with the anti-rotation key.
