Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as Figure 1-13 As shown, the present invention provides a kind of injection mold that can adjust the length of pipe fittings, comprises fixed template 1, movable template 2 and core 3, and described fixed template 1 is provided with first cavity block 11, and described movable template 2 is provided with The second cavity block 21, the first cavity block 11 and the second cavity block 21 form a tubular cavity with an opening, and the core 3 is core-pulled from the opening and placed inside the tubular cavity, so The outer wall of the core 3, the inner wall of the first cavity block 11, and the inner wall of the second cavity block 21 form a tubular forming cavity,

[0038] The core 3 is sleeved with an adjustment sleeve 4, and the inner end of the adjustment sleeve 4 extends into the tubular forming cavity; the opening of the tu...

Abstract

The invention discloses an injection mold capable of adjusting the length of a pipe fitting. The injection mold comprises a fixed mold plate, a movable mold plate and a mold core. A first cavity blockis arranged on the fixed mold plate, a second cavity block is arranged on the movable mold plate, and the first cavity block and the second cavity block form a tubular cavity with an opening. The mold core is arranged in the tubular cavity in a core pulling manner from the opening, the outer wall of the mold core, the inner wall of the first cavity block and the inner wall of the second cavity block form a tubular forming cavity, the mold core is sleeved with an adjusting sleeve, and the inner end of the adjusting sleeve stretches into the tubular forming cavity. An axial adjusting and fixingdevice is arranged at the opening of the tubular cavity. After the adjusting sleeve slides to a required position on the mold core, the adjusting sleeve is fixed to the axial adjusting and fixing device so as to change the length of the tubular forming cavity. According to the scheme, adjustment is convenient, direct operation can be conducted on a machine table, size adjustment is accurate, andformed products do not need to be cut.

Description

technical field [0001] The invention relates to the technical field of forming molds, in particular to an injection mold with adjustable length of pipe fittings. Background technique [0002] The molding methods of pipe fittings in the prior art are mainly divided into two types. [0003] One is obtained by injection molding. The length of the injection mold is fixed and only a single length of pipe fittings can be produced. When other lengths need to be injected, the mold needs to be re-opened or made into different inserts, resulting in higher manufacturing costs. and the difficulty of replacement. [0004] The other is obtained by extrusion molding. Extruded pipes need to be cut after forming. The manufacturing process is more complicated, and only a single length of pipe can be produced. When other lengths are required, the cutting process needs to be adjusted. bit. [0005] The Chinese patent application number CN201420366630.0 proposes a mold for producing length-ad...
