The shell of the oxygen-hydrogen atomizer is generally prepared by an injection mold. The structural integrity and dimensional accuracy of the product are directly related to the mold of the shell of the hydrogen-oxygen atomizer, because the water vapor contained in the raw materials and the curing process Uneven heat dissipation may lead to incomplete structure or inaccurate dimensions of the prepared hydrogen-oxygen atomizer shell
In addition, the cooling efficiency is not high and the cooling speed is slow, which will also affect the molding efficiency of the hydrogen-oxygen atomizer shell, thereby increasing the cost

Embodiment 1
[0040] Such as figure 1 , 2 , 3, an injection mold for a hydrogen-oxygen atomizer shell, including a panel 1, a sprue sleeve 2, a front template 3, a front mold core 4, a rear mold core 5, a rear template 6, a slider, and a rear mold base 8; the sliders include a first slider 71 and a second slider 72 .
[0041] The panel 1, the front template 3, the front mold core 4, the rear mold core 5, the rear template 6, and the rear mold base 8 are arranged sequentially; On the template 3, the rear mold core 5 fits on the rear template 6; the first slider 71 and the second slider 72 are arranged horizontally opposite each other, and are respectively arranged between the front template 3 and the rear template 6; the rear template 6 passes through the guide column 83 Cooperate with rear die holder 8.
[0042] The front mold core 4, the rear mold core 5, the first slider 71 and the second slider 72 encircle the mold cavity of the hydrogen-oxygen atomizer shell, and the injection hole 3...
Embodiment 2
[0056] Similar to Example 1, but the mold ejector pin material is selected from SKH51. In order to improve the wear resistance and surface hardening of the ejector pin, the ejector pin material is subjected to nitriding treatment, and the nitriding treatment includes the following steps:
[0057] Heat the thimble material, and use a heading machine to directly punch out the head; roughen the lathe, and finally reserve 0.03mm; then centerlessly grind the thimble to make it smooth; machine the head on the lathe, and control the outer circle of the head with centerless grinding ; Then put into the nitriding furnace for nitriding treatment.
Embodiment 3
[0059] Similar to embodiment 1, but the surface of the front mold core 4 and the rear mold core 5 is coated with a protective layer. The preparation method of described protective layer is:
[0060] S1. After dedusting the mold kernels, put them into a sodiumhydroxide solution with a concentration of 5g / L, and degrease them for 10 minutes at an ultrasonic frequency of 45kHz and a temperature of 35°C;
[0061] S2. After the degreasing is completed, put the mold core into a hydrogen peroxide solution with a mass concentration of 2% to activate for 1 min;

Abstract
The invention relates to the technical field of molds, in particular to an injection mold for an oxyhydrogen atomization machine shell. The injection mold for the oxyhydrogen atomization machine shell comprises a panel, a sprue bush, a front mold plate, a front mold core, a rear mold core, a rear mold plate, a first sliding block, a second sliding block and a rear mold base. The panel, the front mold plate, the front mold core, the rear mold core, the rear mold plate and the rear mold base are arranged in sequence. The front mold core and the rear mold core are oppositely arranged up and down, the front mold core is located on the front mold plate in a matched mode, and the rear mold core is located on the rear mold plate in a matched mode. The first sliding block and the second sliding block are horizontally and oppositely arranged and are respectively arranged between the front mold plate and the rear mold plate. The rear mold plate is matched with the rear mold base through guide posts. Uniform heat dissipation in the product curing process is ensured, the structural integrity and the size precision of the oxyhydrogen atomization machine shell are ensured, the cooling efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to an injection mold for a shell of a hydrogen-oxygen atomizer. Background technique [0002] Hydrogen and oxygen atomizer is an important medical and health care equipment, which can provide hydrogen and oxygenmixed gas, enter the human body through the respiratory system for disease treatment, and at the same time, it can be mixed with atomized liquid particles for medical institutions and families to atomize the human body For inhalation and humidification therapy. The shell of the oxygen-hydrogen atomizer is generally prepared by an injection mold. The structural integrity and dimensional accuracy of the product are directly related to the mold of the shell of the hydrogen-oxygen atomizer, because the water vapor contained in the raw materials and the curing process Uneven heat dissipation may lead to incomplete structure or inaccurate dimensions of the prepared hydrogen-oxygen ...
