Description

Technical Field

[0001] The utility model relates to the field of mold cores, in particular to an injection molding mold core capable of rapidly dissipating heat. Background Art

[0002] The mold core is a key component in the mold. It is responsible for forming parts in the mold, such as the inner hole of the product, and plays a role in positioning, supporting and compacting. The mold core is usually located in the center of the mold, and its shapes are various, including straight, round, flat, etc., to meet different processing needs. In order to facilitate the heat dissipation of the mold core, it is necessary to use an injection molding mold core that can quickly dissipate heat. For example, the prior art Chinese patent publication number "CN218399250U" discloses a multi-cavity front mold core, including a base and a front mold core, a support seat is fixedly installed on the upper end of the base, and a front mold core is fixedly installed on the support seat. The lower end of the front mold core is provided with a number of equally spaced heat dissipation ports, and the upper end of each heat dissipation port is spaced no more than 5 mm from the bottom of the mold cavity on the front mold core. A water storage tank is opened on the base by setting a water storage tank, and a water storage tank is opened on the base by setting a water storage tank. A support seat is provided with a through slot, and air inlets are arranged on both sides of the through slot and are externally connected to a cold air supply device to transport cold air into the through slot, while the water storage tank is externally connected to an ice water supply device through the water inlet, and heat dissipation ports are provided on both sides of the bottom of the front mold core, and a heat dissipation plate is inserted and installed through the bottom thereof and is located in the heat dissipation port, so that the heat dissipation port is connected to the through slot, and the heat dissipation plate is connected to the water storage tank, and then the mold cavity of the front mold core is cooled by water cooling and cold air, thereby improving the heat dissipation efficiency and solving the problem of low cooling efficiency.

[0003] Although some mold cores can achieve the effect of heat dissipation, in actual operation, similar mold cores only dissipate heat through heat dissipation plates. On the one hand, the heat dissipation effect is poor, and on the other hand, it cannot achieve the effect of rapid heat dissipation. In addition, it is also considered that the heat dissipation plate needs to be cooled immediately after heating to make the injection molded parts separate from the mold core. However, the alternation of hot and cold requires frequent replacement of the heat dissipation plate. If it cannot be replaced quickly, it will affect production efficiency. Utility Model Content
