Problems solved by technology
However, sometimes the center of the product deviates from the center of the mold, resulting in unbalanced force on the molding surface of the mold, and warping of the molded product.
[0004] In order to solve the problem of uneven force on the molding surface of the mold and warpage of the product, the existing technology is to add a balance block to the mold. Adding a balance block can improve the situation of force imbalance, but the improvement effect is not obvious, and the entire mold is still not stable. balance
[0005] In view of this, it is necessary to develop a balance structure of the mold to solve the above-mentioned problems of unbalanced force and product warpage due to the deviation of the center of the product from the center of the mold

The invention provides a balancing structure of a die. The die comprises a female die side and a male die side, wherein an upper fixing plate and a female die plate are arranged on the female die side; a male die plate, an upper ejector plate, a lower ejector plate, a lower fixing plate and two foot pads are arranged on the male die side; the two foot pads are arranged between the male die plate and the lower fixing plate. The balancing structure of the die comprises two balancing blocks and a plurality of balancing columns, wherein the two balancing blocks are fixed in the female die plate and the male die plate correspondingly; the balancing blocks are opposite to a direction in which a product center deviates from a die center; the plurality of balancing columns are fixed on the outer side of the female die side and the outer side of the male die side near the balancing blocks respectively. Through the balancing structure of the die, the die is balanced through a manner of the combination of the balancing blocks and the balancing columns; when the product center deviates from the die center, the balancing structure of the die is capable of overcoming the condition with uneven stress and avoiding warping of a product.
Description
【Technical field】 [0001] The invention relates to a balance structure, in particular to a balance structure of a mold. 【Background technique】 [0002] The plastic parts of the product will be molded using plastic molds, such as plastic parts such as housings of electronic products. Due to the popularity of electronic products, the improvement of plastic molds has also become a subject of extensive research. [0003] When molding plastic products, the product center, molding center and mold center must be consistent to form the product normally. However, sometimes the center of the product deviates from the center of the mold, resulting in unbalanced force on the molding surface of the mold and warping of the molded product. [0004] In order to solve the problem of uneven force on the molding surface of the mold and warpage of the product, the existing technology is to add a balance block to the mold. Adding a balance block can improve the situation of force imbalance, but...
