Problems solved by technology

[0003] In the prior art, in order to facilitate demoulding after molding, it is necessary to spray a layer of release agent on the inner wall of the mold. As the production tempo increases, the number of times of spraying the demoulding agent will also increase, thereby reducing the production tempo and seriously affecting the plastic The production efficiency of the product; there is another way of demoulding is to increase the demoulding mechanism, such as the ejector pin or the top plate, etc., and use the push of the ejector pin or the top plate to push the finished product out of the mold. This method will cause indentations on the surface of the plastic product and affect the quality of the product. Yield rate

Embodiment 1

[0037] Such as Figure 1 to Figure 11 As shown, the high-efficiency injection mold that is convenient for demoulding in this embodiment includes a fixed mold 1100 and a movable mold 1200. The fixed mold 1100 is provided with several spraying mechanisms for spraying the release agent. The nozzles of the spraying mechanisms 1110 are all facing the inner cavity of the fixed mold 1100; the movable mold 1200 is arranged below the fixed mold 1100, and the outer peripheral surface of the movable mold 1200 is provided with a number of blowing holes 1210 for blowing air into the plastic product. Air blowing on the surface is used for auxiliary demoulding. The air blowing holes 1210 are provided with a first hole blocking post 1220. The end face of the first hole blocking post 1220 is flush with the outer surface of the movable mold 1200. The end face of the first hole blocking post 1220 is consistent with the shape of the mold surface, thereby ensuring the smoothness of the product sur...

Embodiment 2

[0053] Such as Figure 12 As shown, the high-efficiency injection mold for easy demolding in this embodiment is different from the above embodiment in that the connection between the blowing hole 1210 and the first sliding hole 1230 is not provided with a rubber stopper 1211 . During the injection molding process, control the solenoid valve of the air blow hole 1210 so that it does not need to blow air or generate negative pressure in the air blow hole 1210. As the raw material in the molten state enters the mold cavity, the air blow hole 1210 will discharge the air in the mold cavity , to prevent air bubbles, after the injection molding is completed, the first retaining hole column 1220 is moved, and the raw material entering the first sliding hole 1230 is pressed into the mold cavity to ensure the compactness of the plastic product in the mold.

[0054] The technical solution in this embodiment eliminates the need for additional vent holes in the mold, thereby further ensuri...

Abstract

The invention discloses an efficient injection mold facilitating demolding. The efficient injection mold comprises a fixed mold and a movable mold, a plurality of spraying mechanisms are arranged on the fixed mold and are used for spraying demolding agents, spray heads of the spraying mechanisms face the interior of an inner cavity of the fixed mold, the movable mold is arranged below the fixed mold, a plurality of air blowing holes are formed in the outer peripheral surface of the movable mold, are used for blowing air to the inner surfaces of plastic products for auxiliary demolding, the airblowing holes are provided with first hole blocking columns, the end surfaces of the first hole blocking columns are flush with the outer surface of the movable mold, the first hole blocking columnsare driven by a first driving cylinder so that the first hole blocking columns can control blowing and sealing of the air blowing holes. According to the efficient injection mold facilitating demolding, the efficiency of demolding operation can be improved on the premise of ensuring the product appearance.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a high-efficiency injection mold that is easy to demould. Background technique [0002] With the development of society, the amount of plastic products in our life is increasing. Due to its advantages of cheap price, convenient processing, light weight and good performance, more and more products are made of plastic materials. Most of the plastic products are processed by injection molding process, that is, the plastic in the molten state is injected into the cavity of the accommodation mold through the injection molding machine, the plastic is cooled in the cavity, and then shaped, and then the cavity is opened to take out the plastic product. [0003] In the prior art, in order to facilitate demoulding after molding, it is necessary to spray a layer of release agent on the inner wall of the mold. As the production tempo increases, the number of times of spraying the demoulding ag...
