Embodiment Construction

[0012] Figure 1-3 Shown is the relevant explanatory drawing of the present invention;

[0013] A biconical sprue gate bushing, comprising a first runner piece 1, a second runner piece 2, a first piece screw 3, a second piece screw 4, a positioning pin 5, and a plywood fastening Screw 6 spherical nozzle surface 7, first conical main runner 8, second conical main runner 9, injection inlet 10, such as figure 1 , figure 2 shown.

[0014] The sprue bushing is composed of the first runner piece 1 and the second runner piece 2 through the installation and combination of the plywood fastening screw 6 and the positioning pin 5, and is connected by the first piece screw 3 and the second piece screw. 4 Install on the required sprue bushing mold.

[0015] The unilateral composition of the runner on the first runner block 1 of the sprue bushing is composed of the first conical main runner 8, the second conical main runner 9, and the injection molding inlet 10. The spherical ...

Abstract

The invention provides a double-cone-shaped main runner sprue bushing. The double-cone-shaped main runner sprue bushing comprises a first runner splice block, a second runner splice block, a first splice block screw, a second splice block screw, positioning pins, plywood fastening screws, a spherical crown nozzle surface, a first cone-shaped main pouring runner, a second cone-shaped main pouring runner and an injection molding inlet. A single edge of the first runner splice block of the sprue bushing is composed of the first cone-shaped main pouring runner, the second cone-shaped main pouring runner and the injection molding inlet, and the spherical crown nozzle surface is used for being in butt joint with a spray pipe nozzle ball of an injection molding machine. By the adoption of the double-cone-shaped main runner sprue bushing, the requirement for forming an eccentric pouring main runner on a mould is met; compared with a traditional oblique sprue bushing, materials can flow more smoothly when injection molding is conducted in the main runner, the requirements for pouring of two independent runners can be met at the same time, pressure losses are small, machining is easy, material discharging is smooth, and mould production cost and product injection molding cost are reduced; the structural design is reasonable, working is stable, both safety and reliability are guaranteed, and using is convenient.

Description

technical field [0001] The invention relates to the field of injection mold mechanism design, in particular to a biconical sprue gate bushing. Background technique [0002] When designing the gating system of injection molds, the gate bushing is generally designed in the center of the mold. The inclined gate bushing can solve the problem of eccentric installation of the straight gate, but it cannot meet the needs of simultaneous independent pouring of more than two runners. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a biconical sprue gate bushing, which is reasonable in design, compact in structure, stable in operation, safe and reliable, and convenient to use; in order to solve the above-mentioned existing technical problems, the present invention adopts the following scheme : A double-conical sprue gate bushing, comprising a first runner piece, a second runner piece, a first piece screw, a second piece scr...
