Embodiment 1

[0053] The resin material is formulated according to the following ratio, and the production status has been verified on site.

[0054] Material PC-3451 PH-3911-1 PH-3952-1 hardness Proportion 100 65 52 Shore A85

[0055] Remove air bubbles before stirring. The volume of the barrel is 5 times that of PC-3451, and a 5-liter barrel is used for 1 liter. Vacuum the vacuum pump for 5min. Repeat the above steps for PH-3911 / PH3952.

[0056] The resin is stirred in the vacuum mixing tank to keep the material in a vacuum state. The total stirring time is 3-4 minutes. After the resin is mixed and the casting is completed, try to control it within 20 minutes. After the resin is stirred, the casting will solidify and the flow rate will gradually decrease. Reducing the time for stirring can better maintain the fluidity of the resin during the initial casting, so that the material can fully flow into the threaded hole and increase the connection.

Abstract

The invention discloses a production method of a flexible resin swaging core, which comprises the following steps: S1, carrying out rough machining on a metal molded surface of a base, carrying out sand blasting treatment, and then cleaning; s2, threaded holes with cross angles are additionally formed in the rough machining face of the base, and after surface cleaning, a foam cavity is used for sealing; s3, pouring a prepared resin material between the cavity and the base, and curing; and S4, after the resin material is cured, the foam cavity is removed, then the resin molded surface is processed according to optimized processing data, the pressing core can reach the grinding-in rate of 95%-100%, and zero grinding-in of the pressing core is achieved. According to the flexible resin pressing core and the production method thereof, the bonding strength of epoxy resin and the cast iron pressing core is enhanced, the height of a resin molded surface is reduced, the application range is expanded, and the material cost is reduced.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a flexible resin pressing core and a production method thereof. Background technique [0002] During the production process of the stamping die, the process part is placed on the punch, and the pressing core is above the process part. The pressing core provides sufficient pressing force to ensure that the position of the part is stable during the stamping process and the edge position does not move. Existing stamping dies mainly use metal pressing cores, and the metal pressing method is the mainstream method of mold pressing at the present stage. Research and matching methods are generally used to ensure that the pressing cores meet the requirements for coloring, precision, and surface quality of the parts. However, after years of use, the shortcomings of traditional press cores such as crushing, poor coloring, and long research and development cycles have gradually been ma...
