[0002] An injection molding machine is a device used to produce plastic products, also known as an injection molding machine. Injection molding production refers to the process of using an injection molding machine to heat and melt plastic particles, inject them into a mold, and cool and mold them under certain pressure and temperature conditions, such as the processing of storage box products.

[0003] In the injection molding process, mold removal is a key step that directly affects the molding efficiency and quality of the product. After the product has cooled, the mold is first removed and the mold is opened. At this time, the product is often in close contact with the mold, making it inconvenient to remove. A suction cup or clamping device is required to remove the product, which is a cumbersome operation. In view of the above problems, a new mold removal device is needed to remove the product more conveniently and quickly. Utility Model Content

[0006] As an improvement, the lifting structure includes a lifting block and a lifting cylinder; the lifting cylinder is fixedly connected above the lifting block, and the lifting cylinder is fixedly connected to the lower closing block.

[0007] As an improvement, a motor is arranged in the fixed cylinder, and a screw rod is fixedly connected to the output shaft of the motor; the lifting block is threadedly connected to the screw rod; a limit rod is fixedly arranged in the fixed cylinder, and the lifting block is slidably sleeved on the limit rod.

[0008] As an improvement, the auxiliary material picking structure includes a pressure plate and a sliding rod; the sliding rod slides through the upper mold body, the upper end of the sliding rod is fixedly connected to the pressure plate, and the lower end of the sliding rod is fixedly connected to the ejection plate; a rebound spring is arranged between the pressure plate and the upper mold body and is sleeved on the sliding rod.

[0009] As an improvement, a card slot is provided in the upper mold body, and a card block inserted into the card slot is fixedly provided on the lower closing block.

[0010] As an improvement, an injection hole is provided on the upper mold body, and a through hole corresponding to the injection hole is provided on the ejection plate.

[0011] Beneficial effects of the utility model:

[0012] The upper mold body is a frame body that opens downwards, and a lower closing block is arranged below the upper mold body, and the lifting structure is fixedly connected to the lower closing block; by setting the lifting structure, the lower closing block can be driven to rise and fall, so that rapid demolding can be achieved, and because the upper mold body is set as a frame body that opens downwards, when the lower closing block is separated from the upper mold body, the product easily has a tendency to move downward under the action of gravity.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] according to Figure 1-4As shown: the utility model provides a mold removal device for an injection molding machine: it includes a base 1, on which a support frame 2 and an injection molding machine 3 are fixedly arranged upward in sequence; an upper mold body 4 is fixedly arranged inside the support frame 2, and the upper mold body 4 is a frame body opening downward; a lower closing block 5 is arranged below the upper mold body 4; a fixed cylinder 62 is fixedly arranged inside the base 1, a lifting structure 6 is arranged inside the fixed cylinder 62, and the lifting structure 6 is fixedly connected to the lower closing block 5; an ejection plate 74 is arranged inside the upper mold body 4, and the ejection plate 74 is located and fits the inner wall of the upper mold body 4; an auxiliary material removal structure 7 is slidably arranged above the upper mold body 4, and the auxiliary material removal structure 7 is fixedly connected to the ejection plate 74.

[0020] The present application configures the upper mold body 4 as a downwardly opening structure, and the lower closing block 5 can be driven to rise and fall by configuring a lifting structure 6, and the auxiliary material removal structure 7 is used to push the product downward, so that the product can be taken out while the mold is quickly removed, greatly increasing the mold removal efficiency.

[0021] The lifting structure 6 includes a lifting block 66 and a lifting cylinder 61; the lifting cylinder 61 is fixedly connected to the top of the lifting block 66, and the lifting cylinder 61 is fixedly connected to the lower closing block 5.

[0027] It should be noted that the mold removal device is suitable for injection molding of daily plastics.

[0028] Principle of the utility model

[0029] like Figure 1 The figure shows the mold closing state, the lower closing block 5 closes the bottom of the upper mold body 4, and the injection molding machine 3 is provided with a nozzle connected to the injection hole 10. The molten plastic is injected into the mold through the nozzle and the injection hole 10, so that the plastic is formed and cooled in the upper mold body 4. After cooling, the product needs to be taken out, such as Figure 2 As shown, the motor 64 is started, and driven by the lifting block 66 and the lifting cylinder 61, the lower closing block 5 moves downward, thereby opening the mold, and at this time, the lower closing block 5 no longer closes the upper mold body 4. Under the action of gravity, the product in the upper mold body 4 can easily fall out, so that it is convenient to take out the product. The product can be directly taken out while the mold is removed, which greatly improves the efficiency of mold removal.

[0030] If the product is stuck in the upper mold body 4, directly press the pressing plate 72 so that the pressing plate 72 drives the ejection plate 74 to move downward, thereby assisting in ejecting the product. At the same time, the pressing plate 72 compresses the rebound spring 73. After the product is ejected, release the pressing plate 72. Under the action of the rebound force of the rebound spring 73, the ejection plate 74 and the pressing plate 72 return to their original positions, which is convenient for the next injection molding of the product and easy to operate.

[0031] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
