Description

Technical Field

[0001] This utility model belongs to the technical field of high voltage insulation, specifically relating to a mold for preparing epoxy test pieces with adjustable clamps. Background Technology

[0002] Epoxy resin is widely used in the power industry due to its excellent insulation and mechanical strength. Nano- or micro-modified epoxy samples often require thin sheet-like specimens with a thickness of less than 1 mm for testing related properties (such as thermal conductivity, electrical conductivity, breakdown field strength, space charge, and tensile strength). Existing molds for preparing thin sheet-like specimens mostly employ a sandwich structure, fixing the middle layer by pressing together upper and lower plates, and then casting epoxy resin into the hollow part of the sandwich to prepare epoxy resin samples of different thicknesses.

[0003] However, the existing molds used for preparing epoxy test pieces typically use screws to connect and adjust the distance between the clamping plates. This method of adjustment not only requires tools but is also very inconvenient to operate, which is not conducive to improving the work efficiency of staff.

[0004] This invention addresses the aforementioned problems by providing a mold for preparing epoxy test pieces with an adjustable clamping plate that is easy to connect. Utility Model Content

[0005] The purpose of this utility model is to provide a mold for preparing epoxy test pieces with adjustable clamps, so as to solve the problem mentioned in the background art that the distance between the clamps of the existing epoxy test piece preparation molds is usually adjusted by screws. This method of adjustment not only requires the use of tools, but is also very inconvenient to operate, which is not conducive to improving the work efficiency of the staff.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a mold for preparing epoxy test pieces with an adjustable clamping plate, comprising an epoxy test piece mold clamping plate and an epoxy test piece mold core disposed at the middle position of the epoxy test piece mold clamping plate;

[0007] The epoxy test piece mold clamping plate has a clamping plate insertion connection groove on its side. An upper fixed insertion connection block is located in the middle of the clamping plate insertion connection groove. An outer connecting post is located at the bottom end of the upper fixed insertion connection block. A rotary adjustment knob is located at the bottom of the outer connecting post. A central connecting threaded post is located in the middle of the rotary adjustment knob. A bottom moving connection block is located at the bottom of the central connecting threaded post. The bottom moving connection block and the upper fixed insertion connection block are inserted into the clamping plate insertion connection grooves of the upper and lower epoxy test piece mold clamping plates. Twisting the rotary adjustment knob drives the central connecting threaded post to move. The movement of the central connecting threaded post causes the upper fixed insertion connection block and the bottom moving connection block to move towards or away from each other. The upper and lower epoxy test piece mold clamping plates move inward, thereby pressing the inner epoxy test piece mold core.

[0008] Preferably, a side-connecting rough block is provided on the side of the upper fixed insertion connecting block and the bottom movable connecting block. The side-connecting rough block is an integral structure with the upper fixed insertion connecting block and the bottom movable connecting block, and the surface of the side-connecting rough block is rough.

[0009] Preferably, the middle position of the epoxy test piece mold core is the mold core injection port, and the mold core injection port is a through groove structure.

[0010] Preferably, a molding mold groove is provided at the bottom of the mold core injection port, and the molding mold groove has the shape of an epoxy test piece.

[0011] Preferably, the rotary adjustment knob is connected to the outer connecting post via a rotating shaft, and the rotary adjustment knob has an internal thread in the middle that matches the central connecting threaded post.

[0012] Preferably, a slope limiting and protective block is provided at the middle position of the mold core injection port, and the slope limiting and protective block has an outward slope structure.

[0013] Preferably, the slope limiting and protective block is provided with a built-in connecting spring body on its side, and the slope limiting and protective block is elastically connected to the epoxy test piece mold clamping plate through the built-in connecting spring body.

[0014] Compared with the prior art, this utility model provides a mold for preparing epoxy test pieces with adjustable clamps, which has the following advantages:

[0015] In an epoxy test piece preparation mold with adjustable clamping plates, clamping plate insertion slots are provided on the side of the clamping plates. An upper fixed insertion block is located in the middle of the clamping plate insertion slots. An outer connecting post is located at the bottom end of the upper fixed insertion block. A rotary adjustment knob is located at the bottom of the outer connecting post. A central connecting threaded post is located in the middle of the rotary adjustment knob. A bottom movable connecting block is located at the bottom of the central connecting threaded post. The bottom movable connecting block and the upper fixed insertion block are inserted into the clamping plate insertion slots of the upper and lower epoxy test piece mold clamping plates. The adjustment knob can be rotated via the threaded action. The movement of the central connecting threaded post increases or decreases the distance between the upper fixed insertion connecting block and the bottom movable connecting block. The distance between the upper fixed insertion connecting block and the bottom movable connecting block controls the distance between the two epoxy test piece mold clamping plates. When the two epoxy test piece mold clamping plates are shortened, they can tightly squeeze and clamp the epoxy test piece mold core. With the improvement of this utility model, the distance between the epoxy test piece mold clamping plates can be adjusted, and the number of epoxy test piece mold core layers clamped between them can be adjusted, thereby increasing the number of epoxy test pieces that can be injection molded at one time, and thus effectively improving the practicality of the epoxy test piece preparation mold with adjustable clamping plates.
