Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] An embodiment of the present invention proposes a process for processing a distributor plate of a hot runner system. refer to figure 1 , the process includes the following steps:

[0032] Step 101, performing rough machining on the plate.

[0033] Specifically, the heat pipe groove, the outlet groove, the main nozzle, the screw hole, the temperature-sensing line hole, the glue inlet and the glue outlet are processed by the CNC center, leaving a margin of 0.3mm.

[0034] Step 102 , processing the outline of the roughly machined board.

[0035] Specifically, the outline of the roughly processed plate is processed by water cutting, so that the outline of the plate is the same as the outline of the target splitter plate with a certa...

Abstract

The invention relates to a technology for machining a spreader plate of a hot runner system. The technology comprises the steps of conducting rough machining on a panel; conducting contour machining on the panel after rough machining; conducting flat grinding on the upper end face and the lower end face of the panel after contour machining, so that a rough part is obtained; conducting deep hole working on the rough part to obtain an insert hole and a runner hole, so that the spreader plate is obtained; conducting quick sand polishing treatment on the runner hole of the spreader plate; installing an insert cooled in a liquid nitrogen environment at the position of the insert hole of the spreader plate, and sealing the punching end of the runner hole of the spreader plate; installing a heating pipe on the spreader plate provided with the insert. The technology aims to solve the technical problems that the finishing degree of the inner wall of a runner hole of an existing spreader plate is low, and color change is hard.

Description

technical field [0001] The invention relates to the technical field of hot runner systems, in particular to a process for processing a splitter plate of a hot runner system. Background technique [0002] The splitter plate distributes the plastic melt transferred from the nozzle of the main channel to the nozzles of each injection point through the runner, which is one of the core components of the hot runner system. The splitter plate can make the mold cavity fill evenly, the plastic melt flow in balance, and the system heat balance. The processing of the flow channel holes in the manifold adopts traditional manual processing. The inner wall of the processed flow channel holes has low smoothness and poor hardness. Excessive sharp corners will be formed at the corners of the flow channels. During injection molding, these positions will cause large pressure loss and bring Due to the high shear heat, when using this splitter plate to produce transparent, pure white or high-gl...
