Anti-warping structure for injection molding piece

Abstract

The invention relates to an anti-warping structure for an injection molding piece. The anti-warping structure comprises a cross rod and through holes I formed in two ends of the cross rod, the throughholes I and the cross rod are integrated, the anti-warping structure is made of stainless steel and is formed through stamping, and a coating layer is further arranged on a surface of the anti-warping structure so as to prevent the anti-warping structure from being exposed in air for a long time or prevent a base material from being corroded in a using process. A groove matched with the anti-warping structure is arranged in an injection molding piece panel and is used for installing the anti-warping structure, and the injection molding piece is fixed to an equipment panel through bolts afterthe anti-warping structure is assembled. An edge of the injection molding piece can be effectively prevented from warping, and a warping phenomenon cannot occur even if the injection molding piece isexposed in the air for a long time or used at a high temperature. Meanwhile, the number of used screws can be reduced so that multiple threaded holes do not need to be arranged in the edge of the injection molding piece, a panel size of the injection molding piece can be reduced, the size of the injection molding piece is decreased, and overall connector size reduction and assembly space reductionare facilitated.

Description

technical field [0001] The invention relates to an anti-warping structure for injection molded parts. Background technique [0002] Injection molded parts have been widely used in low-voltage, high-voltage, signal and integration connectors. When the injection molded parts are released from the mold, they are prone to shrinkage and deformation. In some size restrictions, they will be used longer and have thinner walls. For injection molded parts, the long side of this injection molded part is prone to warping after long-term air exposure and high temperature operation, resulting in the failure of the seal that matches it. Moreover, long-term warping of injection molded parts will cause cracks or even breakage at the warped parts. In the prior art, the long sides of injection molded parts generally need to arrange bolt positions at intervals, such as figure 1 shown. However, the current structure still cannot change the phenomenon that the long side is prone to warping duri...

[0002] Injection molded parts have been widely used in low-voltage, high-voltage, signal and integration connectors. When the injection molded parts are released from the mold, they are prone to shrinkage and deformation. In some size restrictions, they will be used longer and have thinner walls. Injection molded parts, the long side of this injection molded part is prone to warping after long-term air exposure and high temperature operation, resulting in the failure of the matching seal

Moreover, long-term warping of injection molded parts will cause cracks or even breakage at the warped parts. In the prior art, the long sides of injection molded parts generally need to arrange bolt positions at intervals, such as figure 1 shown

However, the current structure still cannot change the phenomenon that the long side is prone to warping during long-term use and high-temperature use, and the current structure needs to arrange multiple bolts at intervals. The number of bolts used is large, which indirectly increases the size of the installation surface and occupies a certain amount of space. Not conducive to the overall miniaturization design requirements of the product
