模具的定期磨光保證（zhèng）了一致（zhì）的衝壓質量。定期打磨模具，不僅可（kě）以提高模具的使用壽命，而且（qiě）可以（yǐ）提高機床的（de）使用壽命。那麽打磨模具時應考慮哪些因素呢？

The regular polishing of the die ensures the consistent stamping quality. Grinding the mold regularly can not only improve the service life of the mold, but also improve the service life of the machine tool. So what factors should be considered when grinding the mold?

（1）在R01-025毫米的情況下，切削刃圓角的銳（ruì）度取決於切削刃的銳度。

(1) In the case of r01-025 mm, the sharpness of the cutting edge fillet depends on the sharpness of the cutting edge.

（2）砂輪表麵應清理幹淨。

(2) The surface of grinding wheel shall be cleaned.

（3）建議使用鬆軟的粗粒砂輪。如WA46KV

(3) It is recommended to use a soft coarse-grained grinding wheel. Such as wa46kv

（4）每次研磨量（刀具）不應超過0013mm。過度磨削會導致模具表麵過熱，相當於（yú）退（tuì）火處理，模具變軟，大大降低模具壽（shòu）命。

(4) The grinding amount (tool) per time should not exceed 0013mm. Excessive grinding will lead to overheating of the die surface, which is equivalent to annealing treatment, making the die soft and greatly reducing the life of the die.

（5）打磨時須添加足夠的冷卻液。

(5) Add enough coolant during grinding.

（6）打磨時，衝頭和下模應固（gù）定牢固，並使用專用工裝夾具。

(6) During grinding, the punch and lower die shall be firmly fixed, and special tooling fixtures shall be used.

（7）模具的（de）研磨量是恒定的。如果達到此值，衝頭將被報廢。如（rú）果繼續（xù）使用，很容易損壞模具和機器（qì）。

(7) The grinding amount of the mold is constant. If this value is reached, the punch will be discarded. If you continue to use, it is easy to damage the mold and machine.

（8）濟南注塑加工廠家提醒您，打磨後，應使用磨刀石處理邊緣，以去除過度鋒利的邊緣。

(8) Jinan injection molding manufacturer reminds you that after grinding, the edge should be treated with a grindstone to remove the excessively sharp edge.

（9）磨尖後（hòu），清洗、退磁、上油。

(9) After sharpening, clean, demagnetize and oil.

注（zhù）意：有很多方法可以磨（mó）快模具，這（zhè）可以通過一個特殊的（de）磨刀器（qì）或在平麵磨床上實現。衝頭和下（xià）模的刃（rèn）磨頻率（lǜ）一般為4:1。磨刀後請調整模具高度。

Note: there are many ways to sharpen the mold, which can be achieved by a special knife grinder or on a surface grinder. The grinding frequency of punch and lower die is generally 4:1. Please adjust the mold height after sharpening.

（1）不正確的銳化方法的危（wēi）害：不正確的銳化會加劇模具刀刃的快速損壞，導致每次（cì）銳（ruì）化的（de）錘擊次（cì）數大大減少。

(1) Harm of incorrect sharpening method: incorrect sharpening will aggravate the rapid damage of the die blade, resulting in a significant reduction in the number of hammers per sharpening.

（2）正確的（de）刃磨方法的好處：定期對模具進行刃磨，可使衝（chōng）孔質量和精度保持穩定。模具的刀刃損壞緩慢，使用壽命較（jiào）長。

(2) Benefits of correct grinding method: regular grinding of the die can stabilize the punching quality and accuracy. The blade of the die is damaged slowly and has a long service life.

技術（shù）人員要了解和掌握基礎的注塑知識，包括低壓保護設置、注射速度（dù）、合模速度、保壓壓力（lì）、鎖（suǒ）模（mó）力、模溫等重要參數，在生（shēng）產操作時，盡量避免傷害模具（jù）。更多相關內容就來網站（zhàn）http://www.lsjtcyjt.cn進行谘詢吧。

Technicians should understand and master basic injection molding knowledge, including low-pressure protection settings, injection speed, mold closing speed, pressure maintaining pressure, mold locking force, mold temperature and other important parameters. During production operations, try to avoid damaging the mold. Come to the website for more relevant content http://www.lsjtcyjt.cn Consult.
