Embodiment Construction

[0034] Such as figure 1 with figure 2 with image 3 with Figure 4 As shown, the mold includes an upper mold body and a lower mold body 1. When the upper mold body and the lower mold body 1 are connected, a molding cavity with a cavity inside is formed between the two. The arc core pulling mechanism in this mold includes Guide block 2, pull rod 3 and core rod 4, the above-mentioned guide block 2 is block-shaped and the guide block 2 is connected with the lower mold body 1, the inside of the above-mentioned guide block 2 has a guide channel 2a, the above-mentioned pull rod 3 is L-shaped and the outside of the pull rod 3 The end is horizontally located in the guide channel 2a and can be connected with the driver. The inner end of the pull rod 3 is vertical and is movably connected with the outer end of the core rod 4. The inner end of the above-mentioned core rod 4 is located in the molding cavity and is connected between the upper mold body and Under the action of the lower...

Abstract

The invention provides an arc core pulling mechanism in a mold, belongs to the technical field of machinery, and solves the problem that the structure in the prior art is complex. The mold comprises an upper mold body and a lower mold body, and when the upper mold body and the lower mold body are connected, a forming cavity of which the interior is a cavity is formed between the upper mold body and the lower mold body. The arc core pulling mechanism comprises a guide block, a pull rod and a core rod, wherein the guide block is blocky and is connected with the lower mold body; a guide channel is formed in the guide block; the pull rod is L-shaped; the outer end of the pull rod is horizontally positioned in the guide channel and can be connected with a driving part; the inner end of the pullrod is vertical and is movably connected with the outer end of the core rod; the inner end of the core rod is positioned in the forming cavity; and an arc pipe section product can be formed in the forming cavity under the action of the upper mold body and the lower mold body. According to the arc core pulling mechanism in the mold, the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to an arc core-pulling mechanism in a mould. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". [0003] Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ce...
