Embodiment 1

[0045] refer to Figure 15 with Figure 16 , Figure 15 with Figure 16 Both are structural diagrams of injection molding products of the present invention. The product is an integrated casing of the main casing and handle of the hair dryer, including the main casing part 510 and the handle part 520. The handle part 520 is the handle casing when the handle is installed, and the hair dryer with integrated structure design The shell is easy to assemble and disassemble, compact in structure, and comfortable to use. The main shell part 510 is cylindrical, with a slide groove 540 and a positioning piece 530 inside, and the connection between the main shell part 510 and the handle part 520 is surrounded by ventilation holes. The bottom of the handle part 520 is provided with a semicircular handle seat.

[0046] together with reference Figure 1 to Figure 14 , is a preferred embodiment, an injection mold for a hair dryer shell, including a front mold 110, a rear mold 120, a left ...

Embodiment 2

[0067] The front shell 210 is separated from the rear mold 120, and the front mold 110 is driven by an independent driver, which can be a hydraulic cylinder or a ball screw structure, and the left oblique push block 211, the right oblique push block 212 and the downward oblique push block 213 is fixedly connected to the front shell 210, after the driver pushes the front mold 110 and the rear mold 120 to match the mold, the front shell 210 pushes the left inclined mold 130 respectively through the left inclined push block 211, the right inclined push block 212 and the downward inclined push block 213. 1, right inclined mold 140 and lower inclined mold carry out mold clamping process, can reach technical effect of the present invention equally.

[0068]In addition, the injection hole 111 can also be set on the back mold 120 in addition to being set on the front mold 110. When the injection hole 111 is set on the back mold 120, the front mold 110 is provided with a water inlet nee...

Abstract

The invention discloses a hair dryer shell injection mold and an injection molding method of the hair dryer shell injection mold. The mold comprises a front mold, a rear mold, a left inclined mold, aright inclined mold and an inner shrinkage mechanism arranged in the rear mold. The inner shrinkage mechanism penetrates through the rear mold and abuts against the deepest part of a first concave cavity. The inner shrinkage mechanism, the front mold, the left inclined mold and the right inclined mold form a main shell cavity of a product main shell part, and the lower middle parts of the front mold and the rear mold form a handle cavity, communicating with the main shell cavity, of a product handle part. Line marks and segment differences generated in the injection molding process are eliminated through the oblique insertion type and the internal contraction structure, the aesthetic effect of the injection molded product is greatly improved, and the injection molding process of the product without line marks and segment differences is realized.

Description

technical field [0001] The invention relates to the technical field of hair dryers, in particular to an injection mold for a hair dryer housing and an injection molding method thereof. Background technique [0002] After the molding of the existing hair dryer housing, there are line marks or step differences left after injection molding, which seriously affects the aesthetic effect. Its molding defects are mainly divided into two types, one is set on the line mark of the symmetry line of the shell of the hair dryer, and the line mark divides the shell of the hair dryer into two halves, which are formed by clamping the left mold and the right mold, and the other is There is a serious step at the rear of the connection between the housing and the handle of the hair dryer. This step is a step difference defect on the case. The step is formed by the rear insert mold during the molding process. The line mark and step difference seriously affect the appearance effect , At the sam...
