Description

Technical Field

[0001] The invention belongs to the technical field of a device for plasticizing or homogenizing molding materials or a device for forcing materials into a mold, and specifically discloses a pressure sleeve production device. Background Art

[0002] In the production process of carbon fiber batteries, the plates and AGM diaphragms need to be stacked according to certain rules, and then pressure is applied to the plates and AGM diaphragms to compress them, thereby reducing the thickness of the plates and AGM diaphragms, thereby reducing the volume of the plates and AGM diaphragms. However, since the material itself has a certain elasticity, when the pressure is removed, the thickness of the plates and AGM diaphragms will increase again. In order to prevent the plates and AGM diaphragms from rebounding after being compressed during the production process of carbon fiber, it is necessary to use a pressure sleeve to press the compressed plates and AGM diaphragms in the pressure sleeve to prevent the thickness of the plates and AGM diaphragms from increasing. The pressure sleeve includes a bottom plate, two side plates and a pressure cover. The two side plates are rotatably connected to the opposite sides of the bottom plate, and reinforcing ribs are provided on the outer walls of the side plates, the bottom plate and the pressure cover.

[0003] In the prior art, when producing a pressure sleeve, a general shape is usually firstly formed by injection molding, and then a specific structure is formed by subsequent cutting. Such a production method has many steps and low efficiency. Summary of the invention

[0004] The invention discloses a pressure sleeve production device, aiming to solve the technical problem of the prior art that when producing the pressure sleeve, the general shape is firstly injection molded, and then the specific structure is cut and processed, thereby resulting in many steps and low efficiency.

[0005] The basic scheme of the present invention is: pressure sleeve production equipment, including a movable template, a fixed template and an injection molding mechanism, the movable template is provided with a first cavity, the fixed template is provided with a second cavity, the first cavity is in the shape of a rectangular groove, the second cavity is the same in shape and size as the first cavity, two vertical protrusions are provided in the second cavity along the vertical direction, the two vertical protrusions divide the second cavity into three rectangular grooves, each rectangular groove is provided with a horizontal groove along the horizontal direction, the rectangular groove on the left and the rectangular groove on the right are provided with a protrusion, the fixed template is fixedly connected to the injection molding mechanism, the fixed template is provided with a feed port, and the injection molding mechanism is used to inject material into the feed port.

[0006] The technical principle and beneficial effect of the present invention are: by setting vertical protrusions, after the workpiece is formed, two connecting lines with a thickness thinner than other parts are generated on the workpiece, and the connecting lines divide the workpiece into three rectangular plates. Since the thickness of the connecting lines is thinner than other parts, the connecting lines are easy to deform, so the rectangular plates can be folded along the connecting lines. At the same time, horizontal protrusions are generated on the surface of the rectangular plates through horizontal grooves, thereby forming reinforcing ribs, which increases the strength of the rectangular plates. By setting protrusions, holes are generated on the rectangular plates, which facilitate the cover plate to be engaged in the holes. The bottom plate and two side plates in the pressure sleeve can be produced at one time through the first cavity and the second cavity.

[0007] Furthermore, the height of the protrusion is equal to the sum of the depths of the first cavity and the second cavity, and the height of the vertical protrusion is less than the depth of the first cavity. Through the above design, the protrusion creates a through hole on the side plate, which facilitates the cover plate to engage with the through hole. Since the height of the vertical protrusion is less than the depth of the first cavity, the thickness of the connection line created by the vertical protrusion is ensured to be thinner than other parts.

[0008] Furthermore, the injection molding mechanism includes an extrusion barrel, a discharge pipe is provided at the end of the extrusion barrel, the discharge pipe is fixed and sealed to the feed port, a motor is fixed to the side of the extrusion barrel away from the discharge pipe, the motor is fixedly connected to a drive shaft, the drive shaft is coaxial with the extrusion barrel and extends into the extrusion barrel, a spiral blade is fixedly connected to the drive shaft located in the extrusion barrel, and a feed pipe is provided on the side wall of the extrusion barrel. Through the above design, the material is put into the extrusion barrel through the feed pipe, and then the drive shaft is driven to rotate by the motor, and the spiral blade is driven to rotate when the drive shaft rotates, and the spiral blade drives the material to flow into the discharge pipe, and then flows into the feed port through the discharge pipe.

[0009] Furthermore, the movable template is provided with a first sliding hole, the fixed template is provided with a second sliding hole, a driving rod is slidably connected in the first sliding hole, one end of the driving rod away from the fixed template extends out of the first sliding hole and is fixed with a limiting boss, an elastic member is fixed between the limiting boss and the movable template, one end of the driving rod away from the limiting boss slides through the second sliding hole, a rack is fixed on the lower end surface of the driving rod located on the side of the fixed template close to the extrusion barrel, a driving wheel is coaxially fixedly connected to the driving shaft between the motor and the extrusion barrel, a spiral sliding groove is provided on the side wall of the driving wheel, and the sliding groove is open at both ends along the axial direction of the driving wheel. Through the above design, the rotation of the driving wheel drives the rack to make a linear motion, and the rack then drives the driving rod to move, and the driving rod drives the movable template to move toward the fixed template through the elastic member until the movable template fits with the fixed template.

[0010] Furthermore, the upper end of the feed pipe is rotatably connected to a rotating ring, the inner diameter of the rotating ring is smaller than the inner diameter of the feed pipe, the lower end surface of the rotating ring is fixedly connected to a suspension rod, the lower end of the suspension rod is fixedly connected to a stirring rod, the stirring rod is located in the feed pipe, a friction belt is provided on the side wall of the driving rod, and the side wall of the rotating ring is in contact with the friction belt. Through the above design, when the driving rod moves, the friction belt is driven to move, the friction belt then drives the rotating ring to rotate, and the rotating ring then drives the stirring rod to rotate in the feed pipe through the suspension rod, so that the material is affected by the rotation of the stirring rod, thereby avoiding the material bridging phenomenon in the feed pipe.

[0011] Furthermore, a cylinder is fixedly connected to the upper side wall of the discharge pipe, and a piston plate is slidably and sealed in the cylinder, a limit portion is provided between the piston plate and the cylinder, and the limit portion is used to prevent the piston plate from rotating, and the piston plate is coaxially threadedly connected to a reciprocating screw, the upper end of the reciprocating screw extends out of the upper wall of the cylinder and is coaxially provided with a friction wheel, the side wall of the friction wheel is in contact with the friction belt, a first one-way bearing is provided between the friction wheel and the reciprocating screw, and a second one-way bearing is provided between the reciprocating screw and the upper wall of the cylinder, the first one-way bearing is locked when the friction wheel rotates forward, and the second one-way bearing is locked when the reciprocating screw rotates reversely. Through the above design, the driving rod drives the friction wheel to rotate through the friction belt. When the friction wheel rotates clockwise, it drives the reciprocating screw to rotate, and the reciprocating screw drives the piston plate to slide back and forth in the cylinder. When the piston plate moves upward, negative pressure is generated in the cylinder, and the material in the extrusion barrel is sucked into the discharge pipe to avoid clogging of the material in the extrusion barrel. When the piston plate moves downward, the piston plate increases the pressure in the cylinder, and the material in the discharge pipe is pressed into the feed port, so that the material is more evenly distributed in the first cavity and the second cavity.

A cylinder 29 is fixedly installed on the upper side wall of the discharge pipe 24, and a piston plate 31 is slidably and sealedly installed in the cylinder 29.

The limiting protrusion is slidably connected to the limiting groove 25. A reciprocating screw 30 is coaxially threadedly connected to the piston plate 31. The upper end of the reciprocating screw 30 extends out of the upper end surface of the cylinder 29. A friction wheel 32 is coaxially provided on the upper end of the reciprocating screw 30. A first unidirectional The bearings are rotatably connected, and the reciprocating screw 30 and the upper wall of the cylinder 29 are rotatably connected through the second one-way bearing. When the friction wheel 32 rotates clockwise, the first one-way bearing is locked, and when the reciprocating screw 30 rotates counterclockwise, the second one-way bearing is locked. The side wall of the friction wheel 32 contacts the friction belt 15. A one-way valve that only allows material to flow out of the extrusion barrel 23 is installed on the discharge pipe 24 between the cylinder 29 and the extrusion barrel 23, and a one-way valve that only allows material to flow into the feed port is installed on the discharge pipe 24 between the cylinder 29 and the fixed mold plate 3.

[0021] The specific implementation process is as follows: start the forward and reverse motor 17, the forward rotation of the forward and reverse motor 17 drives the drive shaft 18 to rotate clockwise, the drive shaft 18 drives the drive wheel 20 to rotate clockwise, and the rotation of the drive wheel 20 causes the slide groove 25 to move relative to the rack 16. When the rack 16 contacts the right opening 26, it slides out of the slide groove 25 from the right opening 26 along the connecting plate 28. At the same time, the rack 16 is driven to move to the right, so that the left tooth enters the slide groove 25 from the left opening 27. Through the above process, the rack 16 drives the drive rod 12 to move intermittently to the right. The rightward movement of the drive rod 12 generates a rightward pressure on the reset compression spring 14, and the reset compression spring 14 then pushes the movable template 1 to move to the right, and the movable template 1 then gradually approaches the fixed template 3 to the right along the guide hole 9.

[0022] When the movable template 1 and the fixed template 3 are fitted together, under the action of the rack 16 and the driving wheel 20, the rack 16 continues to drive the driving rod 12 to move to the right until all the teeth of the rack 16 are located on the right side of the driving wheel 20. At this time, since the movable template 1 and the fixed template 3 are abutted against each other, the return compression spring 14 is compressed by the limiting boss 13, so the driving rod 12 is subjected to a leftward elastic force. Therefore, as the driving wheel 20 rotates, the tooth at the leftmost end of the rack 16 moves to the left under the leftward pulling force of the return compression spring 14, and enters the slide groove 25 from the right opening 26, and then immediately moves to the right along the connecting plate 28 as the driving wheel 20 rotates and slides out of the right opening 26. Therefore, every time the driving wheel 20 rotates one circle, the driving rod 12 produces a reciprocating motion. Since the elastic force of the return compression spring 14 not only acts on the limiting boss 13 but also has a rightward elastic force on the movable template 1, the movable template 1 is always pressed against the fixed template 3 during the reciprocating motion of the driving rod 12. At this time, the material is injected into the feed pipe 33, and the material enters the extrusion barrel 23 from the feed pipe 33. During the process of the material entering the extrusion barrel 23, due to the reciprocating motion of the driving rod 12, the driving rod 12 drives the rotating ring 34 to continuously reverse forward and reverse, so that the rotating ring 34 drives the stirring rod 36 to reverse forward and reverse through the suspension rod 35, thereby continuously stirring the material to prevent the material from being stuck in the feed pipe When the piston plate 31 moves upward, negative pressure is generated in the cylinder 29, thereby sucking the material in the extrusion barrel 23 into the discharge pipe 24 to avoid the material from being blocked in the extrusion barrel 23. When the piston plate 31 moves downward, the piston plate 31 increases the pressure in the cylinder 29, thereby pressing the material in the discharge pipe 24 into the feed port, so that the material is more evenly distributed in the first cavity 2 and the second cavity 4. At the same time, under the action of the one-way valve, the material will not flow back into the extrusion barrel 23.

[0023] When the material is injected, the forward and reverse motor 17 is turned off. When the workpiece is formed, the forward and reverse motor 17 is started and rotated counterclockwise, thereby causing the drive shaft 18 to rotate counterclockwise. The counterclockwise rotation of the drive shaft 18 drives the drive wheel 20 to rotate counterclockwise, causing the rack 16 to enter the slide groove 25 from the right opening 26 and then leave the slide groove 25 from the left opening 27, thereby causing the rack 16 to drive the drive rod 12 to move intermittently to the left, thereby causing the drive rod 12 to pull the movable template 1 to move to the left through the reset compression spring 14, thereby separating the movable template 1 and the fixed template 3, making it easier to remove the workpiece.

[0024] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
