DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-Figure 3The figure shows a mold frame for an injection mold that is easy to demold, including a fixed mold 1, a base 2 is provided on the right side of the fixed mold 1, a sliding mold 3 is provided on the left side of the fixed mold 1, a telescopic cylinder 4 is provided on the left side of the sliding mold 3, a limit block 5 is provided on the telescopic cylinder 4, the limit block 5 is slidably connected to the sliding block 6, the sliding block 6 is slidably connected to the second sliding block 7, and the second sliding block 7 is slidably connected to the base 2. The utility model is connected to the base through the right side of the fixed mold, a sliding mold is provided on the left side of the fixed mold, a telescopic cylinder and a limit block are installed on the left side of the sliding mold, the limit block is slidably connected to the sliding block, and the sliding block pushes the second sliding block to move, thereby effectively solving the problem of collision and damage that may occur in the process of demolding the molded product, and can also significantly improve the demolding efficiency and the appearance quality of the product.

[0020] Furthermore, three sliding rods 201 are provided on the inner side of the base 2, and the three sliding rods 201 are slidably connected to the sliding mold 3. The three sliding rods 201 are in a triangular shape. The design of three sliding rods in a triangular layout on the inner side of the base improves the stability and precision of the injection mold and also enhances the durability of the mold.

[0021] Furthermore, a sliding base 202 for sliding the sliding block 6 is provided in the middle of the base 2. The sliding base 202 is slidably connected to the sliding block 6 and the second sliding block 7. The sliding base 202 is slidably connected to the sliding block and the second sliding block. The limit block is used to limit the movement range of the sliding block and the second sliding block to prevent them from exceeding the predetermined position during the sliding process, thereby ensuring the safety and accuracy of the demoulding process.

[0022] Furthermore, the sliding block 6 is composed of a connecting block 601 and a trapezoidal body block 602. One end of the connecting block 601 passes through the middle of the base 2 and is plugged into the matching limit block 5. The inclined surface of the trapezoidal body block 602 is frictionally connected to the second sliding block 7. The sliding block is composed of the connecting block and the trapezoidal body block, which effectively prevents the sliding block from shifting or shaking during movement, thereby improving the demolding accuracy and quality, ensuring that the second sliding block can slide smoothly on the inclined surface of the trapezoidal body block, and at the same time utilizes friction to maintain a stable connection.

[0023] Furthermore, the second sliding block 7 includes a bearing base 701 and a second connecting block 702. The bearing base 701 is located in the middle of the base 2. The second connecting block 702 is slidably connected to the sliding base 201 and the trapezoidal body block 602. The bearing base in the second sliding block can withstand the pressure from above and evenly distribute it, thereby ensuring the stability of the entire demolding system. At the same time, the second connecting block can slide smoothly along the trajectory of the sliding base and the trapezoidal body block to ensure the smooth progress of the demolding process.

[0024] Furthermore, the sliding block 6 moves left and right through the limit block 5, and pushes the second sliding block 7 to move up and down. The sliding block moves left and right through the limit block, and pushes the second sliding block to move up and down, which improves the stability and efficiency of the demolding process, enhances the flexibility and adaptability of the mold, and avoids sudden drops or collisions that may occur during the demolding process, thereby protecting the integrity and quality of the product.

[0025] In this solution, the workflow is as follows: when the injection molding process is completed, the demoulding operation begins. At this time, the telescopic cylinder starts to work, and the sliding mold drives the limit block to move to the left, and at the same time drives the sliding block to move to the left. As the sliding block moves to the left, the inclined surface of the trapezoidal block in the sliding block will have a friction connection with the second sliding block. This allows the second sliding block to move upward under the push of the trapezoidal block. During the upward movement of the second sliding block, it will gradually drag the mold that has been injected and wait for the staff to collect it, so that the product in the mold can be smoothly detached during the demoulding process, avoiding collisions and damage that may occur during the demoulding method.
