Description

Technical Field

[0001] The utility model relates to the technical field of demolding devices, in particular to an epoxy resin demolding device. Background Art

[0002] When preparing hollow fiber membranes, the common preparation process is to form a porous structure inside the fiber and then fix and protect these hollow fibers through encapsulation. If demolding is required, some measures or chemicals may be taken to remove the encapsulation material so that the hollow fiber membrane can obtain the desired shape and structure. At present, when demolding, an oil-type substance is used to brush a demolding layer inside the mold. After encapsulation is completed, the epoxy resin and the demolding substance do not stick together, and demolding can be easily achieved.

[0003] The demolding device in the prior art 201420267301.6 includes an upper cover plate, a lower cover plate, a shell mold and a mold core. A cylindrical cavity for casting an insulating cylinder is formed between the shell mold and the mold core. A groove is arranged at the bottom of the upper cover plate. The groove corresponds to the upper surface of the cylindrical cavity and is evenly distributed. A detachable gasket is arranged in the groove. The gasket is installed in the groove by connecting bolts. After loosening the connecting bolts, the gasket can be pushed downward from the groove by using a top screw.

[0004] The above structure uses a gasket to demould the insulating tube, but due to the influence of the release agent during the demoulding process, the internal middle demoulding layer will adhere to the surface of the epoxy resin, which is not easy to clean. At the same time, the adhesion layer on the surface will affect the bonding strength of the sealant and there is a risk of leakage. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide an epoxy resin demolding device to solve the problem that the epoxy resin surface is difficult to clean and the adhesive layer on the surface will affect the bonding strength of the sealant.

[0006] Based on the above purpose, the utility model provides an epoxy resin demolding device, including a casting tool, a groove is opened inside the casting tool, an inner film cylinder is detachably installed on the bottom of the casting tool, and an inner groove is opened inside the inner film cylinder; a silicone profiling sleeve is installed inside the groove, a center hole is opened at the center of the silicone profiling sleeve, a glue inlet hole is opened inside the groove, and the silicone profiling sleeve and the glue inlet hole are connected to form a glue inlet channel; the inner diameter of the silicone profiling sleeve matches the outer diameter of the inner groove opened in the inner film cylinder; demolding holes are opened in the groove around the glue inlet hole.

[0007] Preferably, mounting holes are provided inside the casting tool and the inner groove, and bolts are installed inside the mounting holes.

[0008] Preferably, the shape of the silicone profiling sleeve is adapted to the groove provided in the casting tool.

[0009] Preferably, an annular strip is fixedly mounted on the edge of the groove at the bottom of the casting tool, and a groove corresponding to the annular strip is opened on the top of the inner film cylinder.

[0010] Preferably, the inner diameters of the annular strip and the slot match the outer diameter of the silicone profiling sleeve.

[0011] Preferably, there are at least four groups of demoulding holes, and the demoulding holes are distributed around the inside of the casting tooling.

[0012] The beneficial effects of the utility model are as follows: firstly, the casting tool is connected with the inner film cylinder, and then the silicone profiling sleeve is directly placed inside the casting tool, and the glue inlet hole in the middle of the casting tool is passed through the glue inlet hole. At this time, the glue inlet hole and the center hole coincide with each other to form a glue inlet channel. After the packaging is completed, the casting tool is taken out first. Since the silicone profiling sleeve is used to isolate the epoxy resin between the casting tool and the inner film cylinder, the non-stickiness of silicone and epoxy resin is utilized to realize demolding. The overall structure is simple and compact, and it is easy to install. No other components will be introduced during packaging. The surface is smooth after demolding, and there is no need to manually clean the demolding agent. BRIEF DESCRIPTION OF THE DRAWINGS
