Detailed Description
The optical lens module core actuating structure of the present invention will be described in detail with reference to fig. 1 to 9.
As shown in FIG. 1, an optical lens module core actuating structure of the present invention comprises a fixed side and a movable side. The fixed side includes: a fixed side mounting plate 1, a female die plate 2 and a female die core 103. The female die core 103 is arranged in a core hole of the female die plate 2, and the female die core 103 and the female die plate 2 are fixed on the fixed side mounting plate 1 through screws.
The movable side includes: a movable side mounting plate 7, a bearing plate 4, a male die plate 3, a male die core assembly, a male die bushing 202 and an ejector plate. Wherein, the male die bushing 202 is installed in the male die plate 3, the male die bushing 202 and the male die plate 3 are fixed on the carrier plate 4, and the carrier plate 4 is installed on the movable side mounting plate 7. The ejector plate is arranged in the cavity of the bearing plate 4, and comprises an upper ejector plate 5 and a lower ejector plate 6. One end of the male die core component is fixed on the upper ejector plate 5, and the other end of the male die core component is installed in the male die lining 202 through the through holes on the upper ejector plate 5 and the bearing plate 4. The ejector plate moves vertically in the cavity to push the male mold insert assembly to move in the actuation cavity of the male mold insert 202.
As shown in fig. 2, the male mold core assembly includes: the male die core 203, the male die core cushion block 207, the equal-height screw 208, the spring 209 and the screw 205. A male die insert 203 and a male die insert spacer 207 are mounted within the male die bushing 202. The spring 209 is sleeved on the screw 205, and the screw 205 is arranged in a through hole of the contour screw 208 and extends out of the through hole to sequentially connect the contour screw 208, the male die core cushion block 207 and the male die core 203 into a whole. The spring 209 prevents the inner teeth of the male mold core 203 from being too perpendicular, and prevents the male mold core 203 from being close to a single side during assembly, thereby affecting the positioning degree. The spring 209 acts as a correction.
As shown in fig. 3, the fixed side further includes a fixed side fine positioning column 105 mounted in the female mold plate 2 and fixed to the fixed side mounting plate 1. The movable side further includes a movable side fine positioning column 206 installed in the male mold plate 3 and fixed to the carrier plate 4. The fitting taper of the fixed side fine positioning column 105 and the movable side fine positioning column 206 is unilateral 2 degrees, and the taper is fit all around. In the process of die assembly, the male die and the female die are positioned by the fixed side fine positioning column 105 and the movable side fine positioning column 206, so that concentricity of products is ensured.
As shown in fig. 4 and 6, the large ends of the male mold core 203 and the male mold bushing 202 are in solid fit, and the small ends are left empty for 0.006mm on one side, so as to prevent mutual interference and influence on accuracy. The small end is hollow to play a role in exhausting air, thereby being beneficial to molding. The male mold core 203 is provided with an oil groove and an exhaust hole, wherein the oil groove is used for reducing the contact area and is used for lubricating in the operation process. The oil groove is favorable for storing impurities and lubricating. The male mold insert 202 and the male mold insert 203 are in a solid fit, and vacuum is generated in the production, so that an air vent is added to the male mold insert 203. The male die bushing 202 requires concentricity, roundness, cylindricity, and verticality of 0.001mm in the outer diameter and the actuating hole and the yield.
As shown in fig. 1, the fixed side further includes a female mold insert pad 104 disposed in the cavity hole, and the female mold insert pad 104 is fixedly connected with the female mold insert 103 and the fixed side mounting plate 1, respectively. The total length of the master cavity 103 is adjusted by the master cavity spacer 104. The female die core 103 needs to be fixed on the fixed side mounting plate 1 to ensure the stability of the die.
As shown in fig. 8, the female die core 103 is an integral nickel plating die core, and is made of a cylinder by four-sided edging. Four edges are needed to be cut in the 90-degree direction for processing the female die core 103, and a runner and a gate are processed on the end face, so that the eccentricity of a product is corrected by a method of rotating the female die core 103 under the condition that the product is eccentric. The countersunk head of the die core hole of the master template 2 is processed and positioned by only one edging.
The foregoing description of the preferred embodiments of the invention is not intended to limit the scope of the invention, but rather to enable any modification, equivalent replacement, improvement or the like to be made without departing from the spirit and principles of the invention.
