Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to a multi-station integrated molding mold for a radome. Background Art

[0002] The antenna cover is an outer shell that protects the antenna and its components. It has important protective and aesthetic functions. It not only needs to have good mechanical strength and weather resistance, but also should produce minimal interference to signal transmission. Therefore, the material selection, structural design and molding process of the antenna cover are particularly critical. Among them, injection molding is an efficient production process that can mass-produce plastic parts of complex shapes. The process involves heating plastic particles to a molten state, and then injecting the molten plastic into the mold through an injection system. After cooling, the desired product is formed. Due to its high precision, stability and repeatability, injection molding has become the preferred process for manufacturing antenna covers.

[0003] A Chinese patent discloses an injection molding device (grant announcement number CN102361739B), which includes an inlet component, a plurality of nozzles and a plurality of hoses, each of which is not heated. The hose is connected between the outlet of the inlet component and the corresponding molding material inlet of the nozzle, and is used to transport the molding material from the inlet component to the nozzle. The hose can also be connected between the guide plate and the nozzle, and is used to transport a cooling fluid or an actuating fluid for an actuator to the nozzle or to transport a cooling fluid or an actuating fluid from the nozzle. The nozzle can be fastened to a mold plate of the injection molding device, such as by a threaded bushing. The heated insert can at least partially define the mold cavity to heat the molding material in the mold cavity.

[0004] In the above patents and most existing injection molding equipment, during the injection molding process, the product inside the mold is usually demolded by ejector pins after cooling and molding. However, this process easily leaves ejector pin marks on the surface of the product. There are two main solutions at present: one is to extend the cooling time to ensure that the product is completely hardened before demolding. Although this can reduce the appearance of ejector pin marks, it will significantly increase the molding time of a single product, thereby reducing work efficiency; another method is to improve the cooling effect of the mold, but too low a temperature may cause the raw material to be cooled and molded before it can completely fill the mold cavity, thereby affecting the integrity of the product. To address this problem, we proposed a multi-station integrated molding mold for antenna covers to optimize the injection molding process. Summary of the invention

[0005] The purpose of the present invention is to provide a multi-station integrated forming die for a radome to solve the problems raised in the above-mentioned background technology.

[0010] As a further solution of the present invention, a plurality of connecting rods are fixedly connected between the fixed column and the row of pipes, a first gear is fixedly connected to the sealing rotating sleeve, and a motor is fixedly connected to the side wall of the rotating seat.

[0011] As a further solution of the present invention, a second gear is rotatably connected inside the rotating seat, and the output end of the motor is fixedly connected to the second gear, and a leather toothed belt is sleeved between the second gear and the first gear.

[0012] As a further solution of the present invention, the infusion assembly includes two infusion cylinders respectively sleeved on two inlet and outlet tubes, and the two inlet and outlet tubes are both provided with long infusion holes.

[0021] 3. When the present invention is used, the multi-station design not only prolongs the cooling time of the antenna cover molding, but also significantly improves the production efficiency of the antenna cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1 to 6 In the embodiment of the present invention, the antenna cover multi-station integrated molding mold includes a mold frame assembly 1, the mold frame assembly 1 includes a support base 101, an injection molding machine 102 is fixedly connected to the upper side of the support base 101, and a fixed mold 103 is fixedly connected to the injection end of the injection molding machine 102. A rotating seat 104 is fixedly connected to the upper side wall of the support base 101, and a rotating shell 105 is arranged inside the rotating seat 104. Two special-shaped disks 106 are arranged inside the rotating shell 105. The bottom of the special-shaped disk 106 is designed to be slightly concave inward, and a plurality of protruding components 2 are arranged around the special-shaped disk 106;

[0040] The extending component 2 includes a fixed cylinder 201 fixedly connected to the inner wall of the rotating shell 105, a moving disk 202 is slidably connected inside the fixed cylinder 201, two top plates 203 are fixedly connected to the side wall of the moving disk 202, and the ends of the two top plates 203 away from the moving disk 202 are rotatably connected to rollers 204, two inlet and outlet pipes 205 are fixedly connected to the side wall of the moving disk 202, and the ends of the two inlet and outlet pipes 205 away from the moving disk 202 are connected to the same movable mold 206, and a cooling cavity 207 is excavated inside the movable mold 206, a fixed ring block 208 is fixedly connected inside the fixed cylinder 201, and a thrust spring 209 is fixedly connected between the fixed ring block 208 and the moving disk 202, and the roller 204 is connected to the moving disk 202 through the thrust spring 20 9 is against the side wall of the special-shaped disk 106, the fixed cylinder 201 is fixedly connected with an infusion component 3, the two special-shaped disks 106 are fixedly connected with a mold closing drive component 4, and the movable mold 206 is fixedly connected with an ejection component 5. In the initial state, the movable disk 202 is pushed by the thrust spring 209 so that the roller 204 can be close to the side wall of the special-shaped disk 106. When the rotating shell 105 rotates, it will also drive the roller 204 to roll on the side wall of the special-shaped disk 106. When the movable mold 206 of one of the stations corresponds to the fixed mold 103, the mold closing drive component 4 can be started to push the movable disk 202 to move, so that the movable disk 202 pushes the movable mold 206 to move through the inlet and outlet pipes 205, so that the movable mold 206 and the fixed mold 103 are closed.

[0041] The mold frame assembly 1 also includes a fixed column 107 fixedly connected to the side wall of the two special-shaped disks 106, and the two fixed columns 107 are rotatably connected to a sealing sleeve 108, and the end of the sealing sleeve 108 away from the fixed column 107 is rotatably connected to a row pipe 109, and a plurality of connecting rods 110 are fixedly connected between the fixed column 107 and the row pipe 109. The sealing sleeve 108 is fixedly connected to a first gear 111, and a motor 112 is fixedly connected to the side wall of the rotating seat 104, and a second gear 113 is rotatably connected inside the rotating seat 104, and the motor 112 is fixedly connected to the side wall of the rotating seat 104, and a second gear 113 is rotatably connected inside the rotating seat 104, and the motor 112 is fixedly connected to the side wall of the rotating seat 104, and the ... The output end of 112 is fixedly connected to the second gear 113, and a leather tooth belt 114 is provided between the second gear 113 and the first gear 111. During the injection molding process of the device, the motor 112 can drive the second gear 113 to intermittently rotate 90 degrees. The second gear 113 drives the first gear 111 to intermittently rotate 90 degrees through the leather tooth belt 114. At the same time, the first gear 111 drives the extending component 2, the rotating shell 105 and the sealing rotating sleeve 108 to intermittently rotate 90 degrees through the connecting hard pipe 304, so that the fixed mold 103 can correspond one by one to the movable mold 206 of multiple stations.

[0042] The infusion component 3 includes two infusion cylinders 301 respectively sleeved on two inlet and outlet pipes 205, and the two inlet and outlet pipes 205 are both provided with an infusion long hole 302. A plurality of sealing ring plugs 303 are fixedly connected to the inner wall of the infusion cylinder 301, and a connecting hard tube 304 is connected between the sealing ring plug 303 and the sealing rotating sleeve 108. When the extended component 2 is not in the injection molding state, the coolant will enter from one of the row pipes 109, and then be input into different infusion cylinders 301 through a plurality of connecting hard tubes 304, and then enter into the cooling cavity 207 of the movable mold 206 through the infusion long hole 302, so as to cool the movable mold 206, and then the cooling cavity 207 is cooled. The coolant in 7 is discharged from another inlet and outlet pipe 205, so that the discharged coolant is finally discharged through the discharge pipe 109 on the other side. In the process of closing the movable mold 206 with the fixed mold 103, due to the movement of the inlet and outlet pipe 205, the long infusion hole 302 will be partially blocked by the sealing ring plug 303, resulting in the effective length of the long infusion hole 302 that can transport the coolant being shortened, thereby slowing down the flow rate of the coolant flowing into the movable mold 206, reducing the cooling effect during injection molding to a certain extent, thereby maintaining the appropriate fluidity of the raw material in the mold cavity, which helps to better fill the entire mold cavity and improve the overall integrity of the antenna cover.

[0043] Example 2: Please refer to Figures 7 to 10 Based on Example 1, the mold clamping drive assembly 4 includes a fixed block 401 fixedly connected between the two special-shaped disks 106, and the fixed block 401 is fixedly connected to the side wall of the fixed mold 103 with an electric push rod 402.

[0044] It is worth noting that the power supply of the electric push rod 402 is electrically connected to the fixed column 107 through wires, and the external power supply is electrically connected to the fixed column 107 through a collector ring, so that when the rotating shell 105 rotates, the electric push rod 402 can also receive a stable current.

[0045] The ejector assembly 5 includes an ejector block 501 slidably connected to the inside of the movable mold 206, a plurality of limit sleeves 502 are fixedly connected to the inner wall of the rotating shell 105, a round rod 503 is inserted into the limit sleeve 502, and the round rod 503 is fixedly connected to the ejector block 501, and a return spring 504 is fixedly connected between the ejector block 501 and the movable mold 206. When the rotating shell 105 rotates, it also drives the roller 204 to roll on the side wall of the special-shaped disk 106. Due to the bottom design of the special-shaped disk 106 It is slightly concave inward, so when one of the protruding components 2 rotates to the lower side of the special-shaped disk 106, the roller 204 will move a certain distance under the thrust of the thrust spring 209, so that the movable disk 202 drives the movable mold 206 to move a certain distance through the liquid inlet and outlet pipes 205. However, since the round rod 503 is limited by the limiting sleeve 502, the top block 501 and the round rod 503 cannot move, which will cause the top block 501 to bulge out of the movable mold 206 and eject the cooled antenna cover product.

[0046] It is worth noting that after one of the protruding components 2 is injection molded, the motor 112 will drive the protruding component 2 to rotate 90 degrees upward, so that the protruding component 2 can rotate to the lower side of the special-shaped disk 106 after rotating three stations, which will effectively extend the cooling time of the antenna cover product.

[0047] The working principle of the present invention is:

[0048] When the present invention is used, first, by starting the motor 112, the motor 112 drives the second gear 113 to intermittently rotate 90 degrees, and the second gear 113 drives the first gear 111 to intermittently rotate 90 degrees through the toothed belt 114. At the same time, the first gear 111 drives the extension assembly 2, the rotating shell 105 and the sealing rotating sleeve 108 to intermittently rotate 90 degrees through the connecting hard pipe 304, so that the fixed mold 103 can correspond to the movable molds 206 of multiple stations one by one;

[0049] When the movable mold 206 of one of the workstations corresponds to the fixed mold 103, the electric push rod 402 is started to push the movable plate 202 to move, so that the movable plate 202 pushes the movable mold 206 to move through the inlet and outlet pipes 205, so that the movable mold 206 and the fixed mold 103 are closed. At this time, injection molding can be performed by the injection molding machine 102. At the same time, during the movement of the inlet and outlet pipes 205, a part of the long infusion hole 302 will be blocked by the sealing ring plug 303, resulting in the effective length of the long infusion hole 302 that can transport the coolant being shortened, thereby slowing down the flow rate of the coolant flowing into the movable mold 206, reducing the cooling effect during injection molding to a certain extent, thereby maintaining the appropriate fluidity of the raw material in the mold cavity. This fluidity helps to better fill the entire mold cavity and improve the overall integrity of the antenna cover.

[0050] When one of the extending components 2 rotates to the lower side of the special-shaped disk 106, since the bottom of the special-shaped disk 106 is designed to be slightly concave inward, the roller 204 will move a short distance toward the center of the special-shaped disk 106 under the thrust of the thrust spring 209, so that the movable disk 202 drives the movable mold 206 to move a certain distance through the inlet and outlet liquid pipes 205. However, since the round rod 503 is limited by the limiting sleeve 502, the ejector block 501 and the round rod 503 cannot move, which will cause the ejector block 501 to bulge out of the movable mold 206 and eject the cooled antenna cover product. The ejection state is shown in FIG. Figure 9-10 shown.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
