Example Embodiment

[0017] In order to facilitate the understanding of those skilled in the art, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be noted that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0018] As attached figure 1 , 2 3, a liquid silicone injection mold structure, including a rear mold core 2 fixed on the back template 1 and a front mold core fixed on the front template, the rear mold core 2 is provided with heat insulation panels on its periphery 4. The temperature of the back mold core 2 and the mold base are effectively separated to reduce heat transfer; the back mold core 2 is provided with a pressure-bearing block 6 on the parting surface to avoid pressure damage on the surface of the plastic structure 3 when the mold is closed; 2 There are inserts 7, top block 8 and silicone cold runner parts 9 inside. The top block 8 is...

Abstract

The invention relates to a liquid silica gel injecting and molding mold structure which comprises a rear mold core and a front mold core. The rear mold core is fixed on a rear mold plate, and the front mold core is fixed on a front mold plate; the side edge of the periphery of the rear mold core is provided with a heat insulating plate, the parting surface of the rear mold core is provided with a pressure bearing block, and an inserted component, an ejecting block and a silica-gel cold runner component are arranged in the rear mold core; the rear mold plate, the rear mold core and the inserted component are respectively and internally provided with a heating rod; a piece of heating insulating paper is arranged at the part in which the top of the silica-gel cold runner component abuts against the rear mold core; and the inserted component and the rear mold core form a silica-gel molding cavity with a silica-gel structural component needing to be injected by the silica gel. According to the liquid silica gel injecting and molding mold structure provided by the invention, a low-temperature area of a cold runner in the silica-gel cold runner component is separated from a high-temperature area in which silica gel is molded, and thus the problem that a silica-gel ring is vulcanized for quite a long time due to the low temperature of the low-temperature area of a cold runner so as to cause low production capacity can be solved, the temperature in the high-temperature area is uniform, and the deformation caused by large temperature difference is prevented.

Description

technical field [0001] The invention relates to a liquid silicone injection mold structure. Background technique [0002] The existing waterproof technology for battery products usually uses glue coating, ultrasonic welding, etc. to set a silicone waterproof ring on the groove or rib on the plastic structural parts, or use plastic plus TPU two-color molding method , and finally achieve the purpose of waterproofing. However, due to the need for manual operations in the process of glue coating and ultrasonic welding, the accuracy and stability of the assembly cannot be guaranteed, and the waterproof effect is not good. For the waterproof method of two-color molding of plastic and TPU, on the one hand, the hardness of the TPU material can only reach a minimum of 60 degrees, and the waterproof level of the molded product is greatly limited; on the other hand, although the fluidity of the TPU material is higher than that of ordinary plastic materials Good, but much worse than l...
