Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, 2, 3 and 4, an automobile sound insulation pad mold comprises an upper mold frame 1, a lower mold frame 2, a cavity 11, a mold core 21, a guide pillar 3, a guide sleeve 4 and a guide hole 5, wherein the mold core 21 is fixed on the lower mold frame 2 and is fixed by two rows of 4 pairs of symmetrically arranged bolts 9 in the embodiment so that the mold core and the lower mold frame are stably connected, the cavity 11 is fixed on the upper mold frame 1 and is fixed by two rows of 4 pairs of symmetrically arranged bolts 9 in the embodiment so that the mold core and the lower mold frame are stably connected, the upper mold frame 1 is fixed on a molding press, the guide hole 5 is arranged on the lower surface of the upper mold frame, the guide sleeve 4 is arranged in the guide hole 5, the guide pillar 3 is arranged on the upper surface of the lower mold frame, the guide pillar 3 is arranged corresponding to the guide hole 5, and the upper mold frame 1 and the lower mold frame, the number of the guide posts 3 is 4, the guide posts are distributed on 4 corners of the upper die frame 1, and the guide posts 3 are made of low-carbon steel and have high toughness and low wear rate. The side edges of the upper die frame 1 and the lower die frame 2 are provided with U-shaped grooves, the inside of the die cavity 11 and the inside of the die core 21 are provided with heating pipes of a single-row U-shaped loop, and heat conducting oil is arranged in the heating pipes for circulating heating.
The utility model discloses a car gives sound insulation and fills up mould, the U type inslot of lower die carrier 2 is built-in and is equipped with bolt (not shown in the figure), will descend die carrier 2 to fix subaerial through the bolt, goes up the U type inslot of die carrier 1 and builds bolt (not shown in the figure), will descend die carrier 2 to fix on the hydraulic press through the bolt, goes up die carrier 1 and reciprocates along with the hydraulic press. The mold core 21 is fixed on the upper mold frame 1, the mold cavity 11 is fixed on the lower mold frame 2, in the compression molding process of the automobile sound insulation pad, the upper mold frame 1 and the lower mold frame 2 are extruded through the guide pillar 3 and the guide sleeve 4, and finally the material is made into the automobile sound insulation pad product. Because the size of the automobile sound insulation pad is large, the size of the die is large, the weight of the die is large, and fixed pressing dies are adopted to carry out compression molding production on the automobile sound insulation pad. The heating pipes of the single-row U-shaped loops are arranged inside the cavity 11 and the mold core 21, and heat conducting oil is arranged in the heating pipes for circulating heating, so that the temperature distribution of the molding surface of the mold is uniform, the temperature rise time is short, and the molding quality and the production efficiency of the automobile sound insulation pad product are improved.
The core 21 has a side wall surface with a draft angle of 0.5 degrees. The demoulding inclination of the side wall surface of the cavity 11 is 1 degree. For male die forming, the automobile sound insulation pad product can be tightly attached to the surface of a die due to the shrinkage of materials, and for female die forming, the automobile sound insulation pad product can be separated from the wall surface after being shrunk, so in order to be smoothly demoulded, the side wall surface of the die must have a certain demoulding inclination, the demoulding inclination is larger, the demoulding is faster, the deformation of the automobile sound insulation pad product during demoulding is smaller, and the production efficiency is higher.
The cavity 11 and the core 21 are made of aluminum alloy.
