Description

Technical Field

[0001] The utility model belongs to the technical field of prepolymer particle forming molds, and particularly relates to a prepolymer particle forming mold. Background Technique

[0002] PMI foam is a new type of polymer structural foam material, which has the characteristics of low density, high temperature resistance, good wave transmission, high specific strength, etc., and shows good application prospects in the fields of aerospace, medical, military, electronic communication, radar, etc. Especially in the military industry, more and more attention is paid to using PMI foam to produce and manufacture adapter type products. With the increasingly fierce competition among enterprises in the industry, as well as the urgent need for enterprise development and cost reduction and efficiency improvement, the industry has put forward higher requirements for the material cost, processing cost and production efficiency of PMI foam related products.

[0003] During the processing of PMI foam, it is necessary to first cut the foam in the prepolymer state into the required size, and then put it into the forming mold, apply pressure while heating, heating makes it crosslinked and cured, and the pressure ensures that the material fills every corner of the mold to form the required shape. Since the prepolymer foam needs to be cut before being put into the mold, and the cutting size needs to be adjusted according to the needs at any time, it is difficult to use large cutting tools, and using a small cutting device will generate a large amount of powder dust, which is harmful to the operator.

DETAILED DESCRIPTION

[0015] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0016] Embodiment: A prepolymerized particle forming mold, such as Figures 1-4As shown in the figure, it includes a bottom mold 1 and a cover plate 2. There are a plurality of forming holes 3 arranged in an array in the bottom mold 1. A material passing groove 4 is connected between two adjacent forming holes 3. The cover plate 2 covers the top of the bottom mold 1. A plurality of corresponding fixed through grooves 5 are provided at the edges of the bottom mold 1 and the cover plate 2. A set of locking parts are provided in each group of the fixed through grooves 5. A plurality of injection holes 6 are formed on the upper surface of the cover plate 2. And a cross rib plate 7 is provided on the upper surface of the cover plate 2. A first lifting ring 8 is provided at the middle position of the cross rib plate 7. A feeding assembly is provided on the cover plate 2. The feeding assembly includes a hanging plate 9. A nozzle 10 is installed at a position on the hanging plate 9 corresponding to the injection hole 6 on the cover plate 2.
