Problems solved by technology

The mold is easy to use. However, when preparing the cast body, due to the interfacial tension of the resin, the upper surface of the prepared cast body is uneven and the size tolerance is large, so the upper surface still needs to be polished; The sides are parallel, and the brittle resin cast body is difficult to remove from the mold, and it is easy to break

Embodiment Construction

[0019] The present invention will be described in more detail below with examples in conjunction with the drawings.

[0020] The resin cast body mold of the present invention is composed of at least two double cross components, Figure 4 , 5 Shown is a resin cast body mold composed of four double cross components mismatched, and the bottom is sealed with transparent tape.

[0021] Combine Figure 1-Figure 3 , The double cross assembly 1 includes two short beams 2, a through beam 3, the length of the short beam 2 is twice the thickness of the bending spline of the resin casting body to be prepared plus the width of the through beam, and the distance between the short beams is the resin casting The length of the body bending spline plus the width of the short beam, and the thickness of the short beam is the width of the resin cast body bending spline. The thickness of the through beam 3 is the width of the prepared casting body. Each end of the through beam has a through hole 4, and...

Abstract

The invention provides a resin casting body processing die, which is composed of two double-cross components, the double-cross components comprise a short beam and a through beam, the length of the short beam is more than two times of thickness of the prepared casting body and the width of the through beam, the spacing between the short beams is the length of the casting body and the width of the short beam, and the thickness of the through beam and the width of the prepared casting body. The resin casting body processing die is composed of two double-cross components, which enables flexible combination, convenient assembling and dismounting, and the die can be used for one-time moulding of resin casting body bending spline, a DMA test spline and other splines required to be tested.

Description

Technical field [0001] The present invention relates to a mold, and specifically, drip is a mold for making resin cast bodies. Background technique [0002] Thermosetting and thermoplastic resins such as epoxy resins, unsaturated polyester resins, phenolic resins, polyimides, nylons, etc. are widely used as matrix resins for the preparation of glass fiber reinforced plastics, adhesives, and aviation materials. However, the performance of the resin is closely related to its formulation and production process. The performance of the resin obtained by different formulations and processes is different, so when it is used in different occasions, its performance needs to be tested. Performance testing mainly includes bending performance, tensile performance, dynamic thermomechanical performance, etc. Since most resins are liquid at room temperature, or the first choice to be dissolved in a solvent to form a liquid during processing, it is necessary to prepare solid strips that meet ce...
