Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold for producing needle tester accessories. Background Art

[0002] Die-casting molds are important tools in the production process of die-casting parts. Through the precise design and manufacture of die-casting molds, the shape, size and surface process of die-casting parts can be optimized. The design and manufacture of die-casting molds should meet the requirements of size, shape, structure, surface, material, etc. of die-casting parts to ensure the accuracy, dimensional stability and geometric accuracy of die-casting products, thereby achieving good assembly performance and motion accuracy.

[0003] Mechanical ejection is the most common ejection method. It uses a mechanical device to push the ejector pin to the bottom of the mold, thereby pushing the casting out of the mold. Due to the high speed and force of mechanical ejection, it can cause great damage to the mold, so special care should be taken when using it.

[0004] Hydraulic ejection uses a hydraulic cylinder to push the ejector pin. Compared with mechanical ejection, the hydraulic ejection force is more stable and the damage to the mold is less. However, this method requires the support of the hydraulic system, so it is more troublesome.

[0005] The principle of pneumatic ejection is similar to that of hydraulic ejection, except that a pneumatic cylinder is used instead. Pneumatic ejection is more flexible than hydraulic ejection, but the ejection force is relatively weak and is only suitable for relatively small molds.

[0006] There are various ejection structures for die-casting molds when ejecting castings, such as mechanical ejection, hydraulic ejection, and pneumatic ejection. However, existing die-casting molds of this type are generally not conducive to convenient ejection of needle gauge accessories when in use. The electric type flexibly controls the ejection distance and ejection speed, which is not convenient for opening the mold for maintenance of the die-casting mold, greatly affecting the convenience of ejecting the needle gauge accessories and the convenience of opening the mold for inspection and maintenance of the die-casting mold.
