Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold with an inclined ejector mechanism. Background Technology

[0002] Injection molds are molding and processing tools used to produce rubber and plastic products. Based on their molding characteristics, injection molds are divided into two types: thermosetting plastic molds and thermoplastic plastic molds. Through specific mold cavity structures, plastic products can be given complete structures and precise dimensions. Specifically, molten plastic is injected into the mold cavity under high pressure by an injection molding machine, and after cooling and solidification, the molded product is obtained. The process is stable and efficient, and it is a commonly used tool for mass production of certain complex-shaped parts.

[0003] When processing workpieces with undercuts, injection molds typically use an angled ejector mechanism to facilitate the separation and ejection of the workpiece after molding. However, due to the softening of the workpiece at high temperatures, it may structurally adhere to the angled ejector structure during demolding, leading to demolding failure and affecting the quality of the injection molded product. Furthermore, the cooling rate of the mold is greatly reduced due to frequent processing during injection molding, requiring additional cooling waiting time to ensure demolding quality, which seriously affects the efficiency of injection molding. Therefore, an injection mold with an angled ejector mechanism is proposed. Utility Model Content

Assisted cooling can effectively improve the cooling efficiency of the molding mold base 3 and the inclined ejector support 11. While facilitating the lifting and demolding work of the inclined ejector support 11, it can also effectively shorten the cooling time of the mold. After cooling and shaping, the lower cylinder pushes the drive connecting seat 5 to move upward. The drive connecting seat 5, in conjunction with the drive connecting column 7, drives the upper mold base 6 to move upward. During the process, the inclined ejector support 11 is driven by the drive connecting seat 5 to engage with the slot guide for oblique lifting. The drive connecting seat 5 pushes the workpiece obliquely out from the snap side of the workpiece, completing the demolding work. Then, the workpiece is clamped and removed by a tool. After that, the upper mold base 6 and the inclined ejector support 11 move downward and reset, completing the injection molding work.

[0032] In summary, this injection mold adopts a slanted ejector structure. The slanted ejector support 11 moves up and down following the drive connecting seat 5. During the mold opening process, the slanted ejector support 11 can efficiently and quickly separate the molded workpiece by tilting it upwards. The structure is simple and reliable. Furthermore, it adopts an active heat dissipation auxiliary structure, using the slanted ejector support 11 as an air supply connection structure. After the mold is closed, the upper docking end pipe 14 of the slanted ejector support 11 is connected to the upper docking end hole 15 of the molding mold base 3, which can achieve working connection with the internal air passage 16 of the molding mold base 3.
