Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold that is easy to demold. Background Technology

[0002] Injection molds are specialized tools used in plastic injection molding processes. They mainly consist of high-precision molds and mold supports, and are used to manufacture plastic products of various shapes and sizes. By injecting heated and molten plastic into the cavity of the mold, and then allowing it to cool and solidify, the desired plastic product is finally obtained. Injection molds play a vital role in modern manufacturing, and are particularly suitable for mass production of products with complex geometries and high precision requirements, such as automotive parts, electronic casings, home appliances, and toys.

[0003] Currently, injection molds use inclined supports to demold the molded parts after injection molding. However, due to the long-term alternating high and low temperature processing environment, the surface of the mold is prone to defects such as dents and fine lines. These defects greatly increase the adhesion between the molded parts and the mold, making the demolding process difficult and resulting in poor demolding. Utility Model Content

[0004] The purpose of this utility model is to provide an injection mold that facilitates demolding, in order to solve the problem mentioned in the background art that the mold surface is prone to defects such as dents and fine lines under long-term high and low temperature alternating processing environment, which increases the adhesion between the injection molded part and the mold, leading to difficulties in the demolding process and thus causing poor demolding.

[0013] Preferably, the top of the shaft is threadedly connected to a limiting member, which abuts against the top of the fixing member.

[0014] Preferably, the demolding assembly further includes a round rod, which is fixedly connected to the bottom of the top mold and slidably connected to the bottom of the pad.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting a cleaning component below the mold cavity, the electric telescopic rod on the cleaning component can drive the lubricating component upward to clean and polish the mold cavity after demolding, thereby improving the surface finish of the mold cavity and the smoothness of demolding of the injection molded part;

[0025] like Figure 1-5 As shown, this application provides an injection mold that is easy to demold, including a lower mold plate 1 and a backing plate 101, with the interior of the lower mold plate 1 arranged in the mold cavity 2;

[0026] Specifically, such as Figure 4 As shown, a cleaning component 3 is provided below the mold cavity 2. The cleaning component 3 is used to clean the mold cavity 2. The cleaning component 3 includes a lubricating component 303, which is rotatably connected inside the mold cavity 2. An electric telescopic rod 301 is provided below the lubricating component 303. By providing the cleaning component 3 below the mold cavity 2, the electric telescopic rod 301 on the cleaning component 3 can drive the lubricating component 303 upward to lubricate and polish the mold cavity 2 after demolding, thereby improving the surface finish of the mold cavity 2 and ensuring that each injection molded part can be demolded smoothly.

[0027] The electric telescopic rod 301 is provided with a support rod 302 at its top. The electric telescopic rod 301 is fixedly installed on the top of the top mold 401. A motor is installed on the top of the electric telescopic rod 301, and the output shaft of the motor is fixedly connected to the support rod 302.
