[0027] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides an efficient injection mold for air-conditioning accessories, including a movable mold 2 and a fixed mold 3. After the movable mold 2 and the fixed mold 3 are molded together, a cavity of the same size as the injection molded product will be formed inside. A feed port is opened at the top of the movable mold 2 for adding melted injection molding materials. The movable mold 2 is arranged on the top of the fixed mold 3, a support seat 1 is fixed at the bottom of the fixed mold 3, a bracket 6 is fixed on the side of the fixed mold 3, a hydraulic cylinder 4 is fixed on the bracket 6, the hydraulic cylinder 4 is connected to an external hydraulic pump through a pipeline, and the hydraulic pump provides power for the hydraulic cylinder 4. The end of the hydraulic cylinder 4 passes through the bracket 6 and is fixed to the top of the movable mold 2. A loading plate 5 is arranged inside the fixed mold 3, and also includes: a lifting mechanism 7, the lifting mechanism 7 includes a push rod 72 passing through the bottom of the fixed mold 3, the top of the push rod 72 is fixed to the bottom of the loading plate 5, a connecting frame 71 is fixed on the side of the movable mold 2, the bottom of the connecting frame 71 is movably sleeved on the surface of the push rod 72, and a ring 73 is fixedly sleeved on the surface of the push rod 72.

[0028] like Figure 3As shown, in this embodiment, a circular plate 74 is fixed to the bottom of the push rod 72, and the connecting frame 71 can be fitted with the top of the circular plate 74 by movement. The connecting frame 71 moves downward. When the connecting frame 71 approaches the lowest position, the connecting frame 71 will contact the circular plate 74, and the connecting frame 71 will drive the circular plate 74 to move downward. The circular plate 74 will drive the push rod 72 to move downward, and the push rod 72 will drive the loading plate 5 to move downward, ensuring that the loading plate 5 is reset to the initial position. There is no need to use a spring to reset the loading plate 5, which is more convenient to use.

[0029] like Figure 4 As shown, in this embodiment, a triangular plate 75 is fixed on the surface of the connecting frame 71 and at the corner position. The corner position of the connecting frame 71 is ninety degrees. During use, stress will be concentrated at the corner position. After the triangular plate 75 is set, the triangular plate 75 can share part of the stress, so that the connecting frame 71 is not easy to deform during use, thereby improving the overall structural strength.

[0030] like Figure 4 As shown, in the present embodiment, there are two connecting frames 71, and an X-shaped connecting rod 76 is fixedly connected between the two connecting frames 71. The X-shaped connecting rod 76 serves to connect the two connecting frames 71, thereby ensuring that the two connecting frames 71 rise and fall synchronously, preventing deformation between the two connecting frames 71, and improving the stability of the connecting frames 71 during use.

[0031] like Figure 2 and Figure 3 As shown, in this embodiment, a discharge assembly 8 is provided on the side of the fixed mold 3, and the discharge assembly 8 includes a support plate 81. A cylinder 82 is fixed on the top of the support plate 81 through a mounting seat. The cylinder 82 needs to be connected to an external air compressor through a pipeline, and the cylinder 82 is supplied with air through the air compressor. A sensor 85 is embedded on the top of the ring 73. The sensor 85 is connected to the central processing unit through a wire. The signal of the sensor 85 can be processed by the central processing unit. After processing the signal, the central processing unit can start the cylinder 82. The sensor 85 is electrically connected to the cylinder 82.

[0032] like Figure 2 and Figure 3 As shown, in this embodiment, a push plate 83 is fixed to the end of the cylinder 82, and the angle between the push plate 83 and the cylinder 82 is ninety degrees. The push plate 83 is provided with anti-skid stripes on the side away from the cylinder 82. The push plate 83 can increase the contact area with the side of the injection molded product, and the injection molded product is pushed more stably by the push plate 83. The anti-skid stripes on the surface of the push plate 83 increase the friction with the contact surface, so it is not easy to slide when in contact, and the pushing is more stable.

[0033] like Figure 3As shown, in this embodiment, a reinforcing plate 84 is fixed to the bottom of the support plate 81, and the side of the reinforcing plate 84 is fixedly connected to the side of the fixed mold 3. The cylinder 82 and the support plate 81 both have a downward gravity, and the support plate 81 is fixed only by one end. After the reinforcing plate 84 is set, the reinforcing plate 84 can support the support plate 81, so that the support plate 81 is more stable during use, and after the reinforcing plate 84 is fixed to the side of the fixed mold 3, it can also share a part of the horizontal pulling force of the support plate 81, thereby further improving the stability of the support plate 81.

[0034] like Figure 3 As shown, in this embodiment, triangular through holes are opened on the surface of the reinforcing plate 84. After the triangular through holes are provided, the material usage can be reduced without affecting the structural strength, which can save some resources and improve the utilization rate of materials.

[0035] Working principle: After the movable mold 2 and the fixed mold 3 are closed, the melted injection material is added into the cavity between the movable mold 2 and the fixed mold 3 from the feed port on the movable mold 2. After the materials inside the movable mold 2 and the fixed mold 3 are shaped, the hydraulic cylinder 4 on the top of the bracket 6 is started, and the hydraulic cylinder 4 contracts upward, and the hydraulic cylinder 4 drives the movable mold 2 to move upward. When the movable mold 2 moves upward, the movable mold 2 will drive the connecting frame 71 to move upward, and the bottom horizontal part of the connecting frame 71 slides upward on the surface of the ejector rod 72. When the top of the bottom horizontal part of the connecting frame 71 contacts the circular ring 73, the connecting frame 71 will drive the circular ring 73 to move upward, and the circular ring 73 will drive the ejector rod 72 to move upward, and the ejector rod 72 The carrier plate 5 will be driven to move upward, and the upward movement of the carrier plate 5 will drive the injection molded product to move upward. When the top of the ring 73 contacts the bottom of the rear fixed mold 3, the hydraulic cylinder 4 stops, and the carrier plate 5 has pushed the injection molded product out of the fixed mold 3. At this time, the sensor 85 contacts the bottom of the fixed mold 3, and the sensor 85 will send a signal to the central processor. After receiving the signal, the central processor processes the signal, and then the central processor will send an instruction to start the cylinder 82. After the cylinder 82 is started, the cylinder 82 drives the push plate 83 to move in the direction of the carrier plate 5. The push plate 83 will contact the injection molded product on the top of the carrier plate 5, and the cylinder 82 will push the injection molded product away from the cylinder 82 through the push plate 83. The movable mold 2 is pushed in the direction of the fixed mold 3 to push a part of the injection molded product out of the range of the fixed mold 3. At this time, the injection molded product can be pulled out. After the injection molded product is taken out, the movable mold 2 needs to be reset. At this time, the hydraulic cylinder 4 is started again, and the hydraulic oil extends outward. The hydraulic cylinder 4 drives the movable mold 2 to move downward. During the downward movement of the movable mold 2, the connecting frame 71 is driven downward again. The connecting frame 71 moves downward under the ring 73. At this time, the carrier plate 5, the ejector rod 72 and the connecting frame 71 will move downward by their own gravity. At the same time, at the moment when the carrier plate 5 moves downward, the ejector rod 72 will drive the top of the ring 73 to separate from the bottom of the fixed mold 3. At this time, the sensor 85 senses that it has separated from the bottom of the fixed mold 3. At this time, the sensor 85 sends a signal to the central processing unit, and the central processing unit receives and processes the signal again. After the signal processing and analysis are completed, the central processing unit starts the cylinder 82 to retract until the cylinder 82 retracts to the initial position, and during the period of retraction of the cylinder 82, the hydraulic cylinder 4 continues to drive the movable mold 2 to move downward until the movable mold 2 is again attached to the top of the fixed mold 3, and when the movable mold 2 is about to contact the fixed mold 3, the bottom horizontal part of the connecting frame 71 will contact the circular plate 74, the connecting frame 71 drives the circular plate 74 to move downward, the circular plate 74 drives the push rod 72 to move downward, and the push rod 72 drives the carrier plate 5 to move downward, ensuring that the carrier plate 5 is completely reset, and then it can be used again.

[0036] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
