Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a mold structure for quick straightening of a middle frame insert. Background Technology

[0002] In the injection molding production of mobile phone mid-frame inserts, the inserts must be placed correctly during injection molding; otherwise, they may be damaged during molding. A common practice is to install a spring block on the front mold core. When the injection molding machine closes the mold, the spring block straightens and pushes the insert, which is placed on the rear mold core, into place. In the existing structure, the spring block can only eject 10mm. To increase the stroke and quickly straighten the product, the steel in the front mold core mounting area needs to be reduced, and the spring hole in the spring block also needs to be lengthened. Reducing the steel in the front mold core weakens its strength, and subsequent stroke adjustments become difficult. Therefore, a mold structure for rapid straightening of the mid-frame insert was designed. Utility Model Content

[0003] The purpose of this utility model is to provide a mold structure for quick straightening of the middle frame insert in order to address the shortcomings of the existing technology. The mold structure for quick straightening of the middle frame insert has a novel design and simple structure, and can quickly straighten the insert, thereby improving the quality of finished products and production efficiency.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] A mold structure for quick alignment of a mid-frame insert includes a rear mold core and a corresponding matching front mold core. The upper end of the rear mold core is provided with a convex product cavity, and the upper end of the product cavity is equipped with a product insert. At least one insert positioning pin is also provided on the upper end of the product cavity. The lower end face of the front mold core is equipped with several vertically arranged insert spring pins, and spring pin springs are fitted on the upper ends of the insert spring pins. The spring pin springs are installed in spring blocks, and the spring blocks are installed in spring block receiving holes provided on the upper end of the front mold core. The upper end of the outer wall of the upper end of the spring block is provided with a convex protrusion, and the corresponding matching hanging groove of the protrusion is provided on the upper end of the inner wall of the spring block receiving hole.

[0006] The product mold cavity is equipped with two insert positioning pins at its upper end.

[0007] The lower end face of the front mold core is equipped with four rectangularly distributed insert spring pins.

[0008] The upper surface of the front mold core is equipped with a flow channel plate.

[0009] The beneficial effects of this utility model are as follows: The mold structure for quick straightening of the middle frame insert of this utility model includes a rear mold core and a corresponding matching front mold core. The upper end of the rear mold core is provided with a convex product mold cavity, and the upper end of the product mold cavity is provided with a product insert. At least one insert positioning pin is provided at the upper end of the product mold cavity. The lower end face of the front mold core is provided with a number of vertically arranged insert spring pins, and the upper end of the insert spring pins is fitted with a spring pin spring. The spring pin spring is installed in the spring block, and the spring block is installed in the spring block receiving hole provided at the upper end of the front mold core. The upper end of the outer wall of the upper end of the spring block is provided with a convex protrusion, and the corresponding matching hanging groove of the protrusion is provided at the upper end of the inner wall of the spring block receiving hole. This invention features several vertically arranged insert spring pins mounted on the lower end face of the front mold core. Each insert spring pin has a spring spring fitted at its upper end, which is housed within a spring block. The spring block itself is installed in a spring block receiving hole at the upper end of the front mold core. A convex protrusion is located on the upper outer wall of the upper end of the spring block, and a corresponding matching groove is located on the upper inner wall of the spring block receiving hole. This design eliminates the need to reduce the steel content of the front mold core; only the depth of the spring block receiving hole and the spring spring need to be adjusted, ensuring mold core strength and enabling faster alignment of the insert. Furthermore, since the insert spring pins and spring springs are separate components, they can be quickly and individually replaced during mold repair, reducing production costs and improving production efficiency. Therefore, this invention boasts advantages such as novel design, simple structure, rapid insert alignment, improved finished product quality, and increased production efficiency.
