Description

Technical Field

[0001] The utility model relates to the technical field of conductive foam, in particular to a conductive foam forming mould. Background Art

[0002] Conductive foam is a foam material with conductive properties. It is usually made by mixing polymer foam such as polyester foam, polyether foam, etc. with conductive agents such as carbon powder, metal powder, etc. It is widely used in electrostatic protection, EMI shielding and other fields.

[0003] After the foam layer and the conductive layer in the conductive foam are bonded, a molding mold is needed to press and fix the two together to maintain the structural stability after bonding so that the conductive foam can be quickly shaped. However, the existing molding molds on the market are very inconvenient when loading and unloading. For this reason, we propose a conductive foam molding mold. Utility Model Content

[0004] The purpose of the utility model is to provide a conductive foam forming mold to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A translation mechanism is arranged between the base frame and the forming box, and the translation mechanism comprises a synchronous wheel, a gear and a rack. A rotating shaft is movably installed between the middle parts of the base frame, and the gears are symmetrically arranged outside the two ends of the rotating shaft.

[0009] Preferably, a motor is fixedly installed inside the right side of the top frame, a transmission shaft is fixedly installed on the output shaft of the motor, cams are arranged in the middle and both ends of the transmission shaft, and three of the cams are movably connected to the upper surface of the middle part of the top end of the pressing plate;

[0010] Preferably, a pair of guide grooves are provided on the inner walls of both sides of the top frame, and optical axes are fixedly installed inside the four guide grooves, and the four optical axes are movably sleeved with the four corners of the pressing plate respectively, and a spring is provided at the inner bottom end of the four guide grooves, and the other end of the spring is provided on the lower surface of the bottom end of the pressing plate, and the spring is movably sleeved on the outside of the optical axis;

[0013] Preferably, one end of the rack passes through the base frame and is located outside the base frame.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. This conductive foam forming mold is used in conjunction with a motor, a transmission shaft, a cam, a forming box and a pressing plate. During processing, the conductive foam after bonding is placed on the forming box, and then the motor is started. The motor controls the rotation of the transmission shaft and drives the forming box to move toward the inner side of the chassis. When the transmission shaft rotates, it drives the three cams to rotate. After the three cams rotate, they press the pressing plate downward. At this time, the forming box will move to the bottom of the pressing plate, and the pressing plate will just press the conductive foam in the forming box. After pressing for a certain period of time, the motor is reversed until the forming box and the pressing plate are reset to the initial point. This is more efficient during shaping.

[0016] 2. This conductive foam forming mold is used in conjunction with a motor, a synchronous wheel, a gear, a rack, a slider and a forming box. When the motor controls the rotation of the transmission shaft, the two synchronous wheels cooperate with the belt to control the synchronous rotation of the rotating shaft. When the rotating shaft rotates, it drives the gears at both ends to rotate. After the two gears rotate, they control the rack to move horizontally, so that the molding box is synchronously extended into the base frame. After shaping, as the motor reverses, the molding box will synchronously withdraw from the middle of the base frame, and then the shaped conductive foam can be removed. In this way, no work injury will occur during loading and unloading, and the pressing and loading and unloading are carried out synchronously, making the device easier to operate.

[0023] 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.

[0024] like Figure 1-5 As shown, a technical solution provided by the utility model:

[0025] A conductive foam forming mold comprises a base frame 1, a top frame 2 is fixedly installed on the top of the base frame 1, a forming box 3 is movably installed in the middle of the base frame 1, a pressing plate 4 is movably installed in the middle of the top frame 2, a forming mechanism 5 is arranged between the top frame 2 and the pressing plate 4, and the forming mechanism 5 comprises a motor 501, a transmission shaft 502 and a cam 503; a motor 501 is fixedly installed inside the right side of the top frame 2, a transmission shaft 502 is fixedly installed on the output shaft of the motor 501, cams 503 are arranged in the middle and both ends of the transmission shaft 502, and three cams 503 are movably connected to the upper surface of the middle part of the top of the pressing plate 4; a pair of guide grooves 8 are opened on the inner walls on both sides of the top frame 2, optical axes 9 are fixedly installed inside the four guide grooves 8, and the four optical axes 9 are movably sleeved with the four corners of the pressing plate 4 respectively, and springs 10 are arranged at the bottom ends of the four guide grooves 8, and the other ends of the springs 10 are arranged on the lower surface of the bottom end of the pressing plate 4, and the springs 10 are movably sleeved on the outside of the optical axes 9;

[0026] In this embodiment, during processing, the conductive foam after bonding is placed on the molding box 3, and then the motor 501 is started. The motor 501 controls the transmission shaft 502 to rotate and drives the molding box 3 to move toward the inner side of the base frame 1. When the transmission shaft 502 rotates, it drives the three cams 503 to rotate. After the three cams 503 rotate, they press down the pressure plate 4. At this time, the molding box 3 will move to the bottom of the pressure plate 4, and the pressure plate 4 just presses the conductive foam in the molding box 3. After pressing for a certain period of time, the motor 501 is reversed until the molding box 3 and the pressure plate 4 are reset to the initial point. This is more efficient during shaping.

[0027] like Figure 2, Figure 3 and Figure 5 As shown, a translation mechanism 6 is arranged between the base frame 1 and the forming box 3, and the translation mechanism 6 includes a synchronous wheel 601, a gear 602 and a rack 603. A rotating shaft 7 is movably installed between the middle part of the base frame 1, and the gear 602 is symmetrically arranged outside the two ends of the rotating shaft 7; the rotating shaft 7 and the end of the transmission shaft 502 close to the motor 501 are both provided with synchronous wheels 601, and the two synchronous wheels 601 are movably connected through a belt, and sliders 11 are fixedly installed on both sides of the forming box 3, and a rack 603 is arranged on the other side of the slider 11, and the gear 602 is meshed with the rack 603; one end of the rack 603 passes through the base frame 1 and is located outside the base frame 1;

[0028] In this embodiment, when the motor 501 controls the transmission shaft 502 to rotate, the two synchronous wheels 601 cooperate with the belt to transmit the transmission and thus control the synchronous rotation of the rotating shaft 7. When the rotating shaft 7 rotates, it drives the gears 602 at both ends to rotate. After the two gears 602 rotate, they control the rack 603 to move horizontally, so that the molding box 3 is synchronously extended into the base frame 1. After shaping, as the motor 501 reverses, the molding box 3 will synchronously withdraw from the middle of the base frame 1, and then the shaped conductive foam can be removed. In this way, no work-related injuries will occur during loading and unloading, and the pressing and loading and unloading are carried out synchronously, making the operation of the device easier.

[0029] like Figure 5 As shown, both sides of the bottom frame 1 close to the forming box 3 are provided with sliding grooves 12 which are slidably connected with the slider 11;

[0030] In this embodiment, when the pressure plate 4 moves back and forth, the sliders 11 at both ends of the pressure plate 4 will slide along the inside of the slide groove 12, and one end of the rack 603 is connected to the bottom of one end of the slider 11, and the other end of the rack 603 passes through the outer shell of the base frame 1 and is located outside it.

[0031] Working principle: During processing, the conductive foam after bonding is placed on the molding box 3, and then the motor 501 is started. The motor 501 controls the transmission shaft 502 to rotate and drives the molding box 3 to move toward the inner side of the bottom frame 1. When the transmission shaft 502 rotates, it drives the three cams 503 to rotate. After the three cams 503 rotate, they press the pressing plate 4 downward. At this time, the molding box 3 will move to the bottom of the pressing plate 4, and the pressing plate 4 just presses the conductive foam in the molding box 3. After pressing for a certain period of time, the motor 501 is reversed until the molding box 3 and the pressing plate 4 are reset to the initial point. This is more efficient during shaping. When the motor 501 controls the transmission shaft 502 to rotate, the two synchronous wheels 601 cooperate with the belt to control the synchronous rotation of the rotating shaft 7. When the rotating shaft 7 rotates, it drives the gears 602 at both ends to rotate. After the two gears 602 rotate, they control the rack 603 to move horizontally, so that the molding box 3 is synchronously extended into the base frame 1. After shaping, as the motor 501 reverses, the molding box 3 will synchronously withdraw from the middle of the base frame 1, and then the shaped conductive foam can be removed. In this way, no work injury will occur during loading and unloading, and the pressing and loading and unloading are carried out synchronously, making the operation of the device easier.
