Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a rapid heat dissipation type rubber injection molding machine. Background Art

[0002] Rubber injection molding machine is a kind of equipment used to produce rubber products. It uses rubber as raw material, injects rubber material into the mold through heating and injection processes, and forms rubber products of various shapes after curing and cooling.

[0003] A Chinese patent discloses an injection mold (authorization announcement number CN219686383U). The injection mold described in the patented technology is in the form of a center point injection port, and a locking ear mechanism is arranged on the side of the injection mold. The side of the injection mold spans multiple parting surfaces; the locking ear mechanism is used to control the opening and closing sequence of each parting surface. The utility model adopts a center point injection gate form of multiple parting surfaces. With the help of the locking ear mechanism on the side of the mold, each parting surface can be opened in sequence according to ideal requirements, and the runner can be automatically separated from the injection blank, and fall off and collected at a determined position; it can effectively eliminate the runner removal process in the injection molding production process and greatly reduce the need for manual cleaning operations. The runner cleaning is completed simultaneously with the injection production process, which is almost completely mechanized and automated, with high production efficiency and low probability of product damage.

[0004] This patented technology has the ability to significantly reduce the need for manual cleaning operations when used, but it still has some shortcomings when used, especially in large-scale rubber injection processing, it takes a long time to wait for the cooling time of the injection molded parts inside the mold, resulting in a long mold opening time and reducing the production efficiency of the mold. Therefore, technical personnel in this field provide a fast heat dissipation type rubber injection molding machine to solve the problems raised in the above background technology. Utility Model Content

[0005] 1. Technical solution

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a rapid heat dissipation type rubber injection molding machine, comprising a top plate,

[0008] The injection molding structure includes a movable mold and a fixed mold below the top plate, and an injection molding hydraulic rod whose telescopic end is connected to the upper end of the top plate;

[0009] The heat dissipation structure comprises a water tank, a fan 1 located at the rear end of the water tank, a fan 2 located at both sides above the top plate, a travel plate located at the upper end of the water tank, and a heat dissipation hydraulic rod fixedly disposed on both sides of the upper end of the water tank and having a telescopic end connected to the upper end of the travel plate;

[0010] as well as;

[0011] The water filtering structure comprises a bracket at the lower end of the fixed mold, a vibration motor fixed inside the bracket, springs at the four corners of the fixed mold and the movable mold opposite to each other, a spring at the lower end of the fixed mold connected to the stroke plate, and a spring at the upper end of the movable mold connected to the top plate.

[0012] Furthermore, the outer wall of the injection hydraulic rod is sleeved on the mounting frames fixed on both sides of the upper end of the stroke plate, and both ends of the movable mold are provided with a sliding sleeve, and a guide rod fixed between the mounting frame and the stroke plate is slidably inserted inside the sliding sleeve;

[0013] Specifically, the mounting frame fixes the injection hydraulic rod, and when the fixed mold moves longitudinally, the sliding sleeve slides inside the guide rod to obtain a sliding guide.

[0014] Furthermore, a partition is provided at the rear end of the water tank, the partition corresponds to the fan 1, a water outlet pipe is installed through one side of the upper end of the water tank, and a water inlet pipe is installed through one side of the lower end of the water tank;

[0015] Specifically, water droplets blown by the fan when delivering airflow are intercepted by the partition to prevent the droplets from falling into the environment. The water inlet pipe and the water outlet pipe are used to replace the cooling water and the water after heat exchange.

[0016] Furthermore, a plurality of through holes are provided inside the travel plate;

[0017] Specifically, the liquid dripping from the fixed mold and the movable mold to the upper end of the stroke plate can flow downward through the through hole.

[0018] Furthermore, a side ring is sleeved on the outer wall of the movable mold joint surface, a rectangular guide groove is opened inside the upper end of the side ring, and a guide pipe penetrating the guide groove is arranged at one end of the side ring;

[0019] Specifically, the side ring receives the liquid material dripping from the movable mold to prevent it from dripping onto the fixed mold, and the guide groove guides the collected liquid into the guide pipe and discharges it on one side of the fixed mold.

[0020] Furthermore, two sliding sleeves are embedded and installed at the four corners of the top plate and the stroke plate, two guide rods are slidably inserted inside the two sliding sleeves, one end of the two guide rods inside the top plate is connected to the movable mold, and one end of the two guide rods inside the top plate is connected to the fixed mold, and the outer walls of the fixed mold and the movable mold are both provided with fins distributed at equal distances;

[0021] Specifically, when the movable mold and the fixed mold move, the guide rod 2 slides inside the sliding sleeve 2 to obtain a sliding guide. When docking, the fixed mold and the movable mold effectively correspond, and the guide rod 2 limits the shaking spring to prevent the spring from shifting outward. The fins increase the contact area between the fixed mold and the movable mold and the cold medium, thereby improving the heat exchange effect.

[0022] 2. Beneficial effects

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] The utility model installs the injection molding structure inside the water tank, and the driving member can enter the water tank, and the injection molding is quickly cooled by immersing in cooling water, thereby shortening the mold opening time and improving the processing efficiency of the injection molding parts.

[0025] At the same time, when the cooled mold and the injection molded parts inside the mold are moved out of the water tank, the liquid adhering to its outer wall is blown away by lateral and longitudinal airflow through fans 1 and 2. In this process, the water filter structure drives the mold to vibrate at a high frequency, accelerating the detachment of the liquid, ensuring that the mold is not affected by the liquid material during the next injection molding process after efficient cooling by immersion.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example 1

[0042] See also Figure 1-Figure 5 As shown, this embodiment is a rapid heat dissipation type rubber injection molding machine, including a top plate 106,

[0043] The injection molding structure 100 includes a movable mold 104 and a fixed mold 105 below a top plate 106, and an injection molding hydraulic rod 101 whose telescopic end is connected to the upper end of the top plate 106;

[0044] The heat dissipation structure 200 includes a water tank 202, a fan 1 302 located at the rear end of the water tank 202, a fan 2 303 located on both sides above the top plate 106, a travel plate 206 located at the upper end of the water tank 202, and a heat dissipation hydraulic rod 201 fixedly disposed on both sides of the upper end of the water tank 202 and having a telescopic end connected to the upper end of the travel plate 206;

[0045] The outer wall of the injection hydraulic rod 101 is sleeved on the mounting frame 107 fixed on both sides of the upper end of the stroke plate 206, and the two ends of the movable mold 104 are provided with a sliding sleeve 103, and the inner part of the sliding sleeve 103 is slidably inserted with a guide rod 102 fixed between the mounting frame 107 and the stroke plate 206;

[0046] A partition 203 is provided at the rear end of the water tank 202, and the partition 203 corresponds to the fan 302. A water outlet pipe 205 is installed through one side of the upper end of the water tank 202, and a water inlet pipe 204 is installed through one side of the lower end of the water tank 202.

[0047] Using the heat dissipation structure 200;

[0048] It is worth mentioning that an injection nozzle is installed on the upper end of the fixed mold 105 and is connected to a hose to ensure stable feeding during movement. The injection hydraulic rod 101 drives the top plate 106 to descend longitudinally, driving the movable mold 104 to dock with the fixed mold 105. After the liquid material is injected into the mold cavity, the cooling hydraulic rod drives the stroke plate 206 to descend, driving the injection structure 100 to enter the water tank 202. The injection mold as a whole is immersed in the cooling water inside the water tank 202. The injection mold and the injection molded parts inside are quickly cooled, avoiding the time-consuming cooling waiting time, greatly reducing the cooling and shaping time during the heat dissipation process, and improving the processing efficiency of the injection molding machine.

[0049] Example 2

[0050] See also Figure 1-Figure 5 As shown, this embodiment is based on the embodiment 1 and also includes:

[0051] as well as;

[0052] The water filtering structure 300 includes a bracket 308 located at the lower end of the fixed mold 105, a vibration motor 306 fixed inside the bracket 308, springs 305 located at the four corners of the fixed mold 105 and the movable mold 104 opposite to each other, the spring 305 located at the lower end of the fixed mold 105 connected to the stroke plate 206, and the spring 305 located at the upper end of the movable mold 104 connected to the top plate 106.

[0053] A plurality of through holes 207 are formed inside the travel plate 206;

[0054] The outer wall of the joint surface of the movable mold 104 is sleeved with a side ring 309, and a rectangular guide groove 310 is opened inside the upper end of the side ring 309. A guide pipe 301 penetrating the guide groove 310 is provided at one end of the side ring 309;
