2. Principle of temperature balance: make the temperatures at all parts of the mold cavity approximately equal to ensure that the shrinkage of plastic parts in each cavity is equal.
4.進(jìn)料平衡原則:對于一模多腔的模具,同一塑件應(yīng)從同一位置進(jìn)料,以保證塑件的互換性;流道和澆口的大小、長短應(yīng)與塑件大小相適應(yīng),盡量保證各型腔同時(shí)進(jìn)料,同時(shí)充滿保證每個型腔進(jìn)料均勻
。
4. feeding balance the first mock exam for multi cavity mold, the same plastic parts should be fed from the same position to ensure the interchangeability of the plastic parts. The size and length of the runner and gate shall be consistent with the size of the plastic part, and try to ensure that each cavity is fed at the same time and filled at the same time, so as to ensure that each cavity is fed evenly.
合理設(shè)計(jì)制造注塑模具成型零件的型腔
，保證塑件的成型質(zhì)量，提高模具的生產(chǎn)效率
。
Reasonably design and manufacture the cavity of injection mold molding parts, ensure the molding quality of plastic parts and improve the production efficiency of the mold.
