Abstract
The invention relates to an injection mold for an automobile glass bracket, comprising an upper mold, a lower mold, a slider, an opening insert and a matching insert, the upper mold is provided with an upper slot and a drainage hole, and the lower mold is provided with a The lower slot and the drainage slot, the slider, the upper slot and the lower slot together form a sealing structure, the drainage hole and the drainage slot are connected to each other, and the drainage slot is connected to the lower slot; the lower slot is provided with multiple lower openings , the upper slot is provided with a plurality of upper openings, the opening insert is located in the lower opening, the top of the opening insert passes through the lower working surface of the lower mold or is flush with the lower working surface of the lower mold, and the opening The number of inserts is the same as the number of openings of the car glass bracket, the paired inserts are located in the upper opening, the top of the paired inserts is flush with the upper working surface of the upper mold, and the diameter of the paired inserts is greater than or equal to the opening The diameter of the insert. The automobile glass bracket injection mold improves the production versatility of the automobile glass bracket injection mold and improves the production efficiency of the automobile glass bracket.
Description
Technical field: [0001] The invention relates to the field of mold production, in particular to an injection mold suitable for producing automobile glass brackets and a production method. Background technique: [0002] At present, the lifting and fixing functions of the car side window glass need to be completed by the bracket and the glass lifter. The car glass bracket is usually made of metal material or plastic material. The connection structure, the part of the car glass bracket and the glass regulator is generally fixedly connected by bolts and nuts. At present, the car glass bracket is produced by the corresponding mold, and the size and shape of the car glass bracket are also set according to the shape of the car glass and the shape of the glass regulator; at present, every time a new car glass bracket is developed, It is necessary to make corresponding molds. The existing automobile glass bracket molds cannot manufacture other different shapes of automobile glass br...
