Embodiment Construction

[0015] Shown in the figure is a forming die for the combination structure of a pair of reducing pipe fittings. When the mold was clamped to the die-casting machine, since the core 2, the core 6, the insert ring 7, the silk core 27, the insert ring 28 and the plug 26 were all movable. If the plug is installed, the straight expansion joint can be produced. Replace a core 2 to produce a variable diameter tee. Change two pieces of insert ring 7 and mold core 6, can produce variable diameter four-way pipe etc. In order to form the grooves on both ends of the inner wall, its forming main core adopts the structural form of an assembled assembly, consisting of mandrel 8, tightening nut 9, main block 12, small block 11 and large block 13. When the product is ejected together with the main core, the mandrel 8 and the main block will be pulled out together by the worker or machine at the back, and then the two small blocks 11 will be clamped inward, and the two small blocks 11 will be ...

Abstract

The invention relates to a set of molding die for a telescoping pipe composite structure. The molding die comprises an insert ring, a silk core, an end cap, a guide post, a guide sleeve, a movable die block, screws, a movable die seat block, a roof plate, a support column, a spring, an ejector rod, a supporting plate, a big slice block, a major slice block, a small slice block, a water faucet, fastening nuts, a core rod, a 3' insert ring, a 3' core, a positioning ring, a mold core, a fixed die plate, and the like. The connection mode is shown in the attached drawing of the specification. The die for the structure is quite practical, and can be used for manufacturing plastic pipes and die casting pipes of various specifications. By changing parts, molded pipes of dozens of specifications such as direct connection, diameter change connection, diameter change cross tee and diameter change five-way connection can be produced. Therefore, the multiple purposes of the die are fulfilled and the economic benefit is improved.

Description

technical field [0001] The invention relates to a die-casting mold and a plastic forming mold, and is a forming mold with a combined structure of variable-diameter pipe fittings. Background technique [0002] At present, when molding injection molds and die-casting molds, the following methods are mainly used for the structural design of molded parts: 1. Integral die; 2. Overall embedded die; 3. Partially embedded die; 4. Combination Combined die; 5. Flap-closed die; 6. Integral core; 7. Inlaid combined core; 8. Through-hole forming; 9. Multiple close-to-close combinations; The thread structure on the fixed mold; 11. The structure of the threaded ring. Because some of the above combined parts have a simple mold structure during design and manufacture, but the mold steel is quite wasteful, which greatly increases the cost of the mold. Therefore, it is very difficult in actual processing, installation, debugging and maintenance. Combining the advantages and disadvantages of...
