Description

TECHNICAL FIELD

[0001] The utility model relates to injection mold field, concretely is injection mold for nozzle production. BACKGROUND

[0002] Nozzle is also called as nipple, and the injection mold for nozzle production is a tool specially used for producing plastic nipple. The mold is usually composed of multiple parts, including mold base, mold core, mold cavity, discharge system, etc. The working principle of the injection mold is to inject molten plastic material into the mold, and form the required shape of the nipple product through pressurization and cooling.

[0003] The existing injection mold still has the following defects:

[0004] 1) The existing injection mold has low mold closing precision and is difficult to demold. The existing injection mold is usually composed of an upper mold and a lower mold. During injection molding, molten plastic material is injected into the mold, and the plastic material is injection molded by applying pressure to the upper mold by an injection molding machine. During the injection molding process, the mold cavity is divided into two parts, and the upper mold needs to be actively closed to the lower mold. When the upper mold and the lower mold of the injection mold are combined, they are easily affected by the external injection molding machine. When the injection molding machine drives the upper mold to move, a certain vibration and pressure may be generated, which can easily cause the upper mold and the lower mold to be misaligned, resulting in inaccurate mold closing and low mold closing precision, which can cause the produced products to not meet the quality requirements. At present, when the injection mold is demolded, after the lower mold is separated from the upper mold, the injection molded product is then ejected by an external ejection mechanism. When the injection molded product is ejected, the ejection rod of the ejection mechanism will contact and eject the injection molded product. Since the injection molded product is present in the mold cavity, a large pushing force needs to be generated by the ejection mechanism to eject the injection molded product, which requires a large force to eject the injection molded product. Therefore, the injection molded product can be damaged during ejection, resulting in incomplete demolding and reducing the yield.

[0005] 2) The molten plastic material needs to be cooled for a long time in the mold cavity before it can be taken out. The existing mold usually has heat dissipation holes in the mold to facilitate cooling. The heat dissipation holes are in communication with the mold cavity, and the heat generated after injection molding is directly discharged from the heat dissipation holes. This heat dissipation hole has the problem of slow cooling speed, which is not convenient for rapid cooling, and the heat transfer efficiency is not good, resulting in a long cooling time, which affects the cooling and heat dissipation efficiency. In addition, the heat dissipation holes are designed to be too small, insufficient in number or unevenly distributed, which can cause insufficient heat transfer area and affect the cooling speed.
