[0048] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] like Figure 1-15 As shown, this application provides:

[0050] A double extrusion structure of a vertical extruder comprises a base 1, an upper pressing device 2, a lower pressing device 3, a feeding device 4 and a workbench 5; the feeding device 4 is arranged on the workbench 5, and the feeding device 4 comprises a clamping sleeve 4a, an extension pipe 4b, a first switch valve 4c, an air outlet 4d, a driving device 4e, and a pushing block 4f; the workbench 5 is provided with a through hole penetrating along the height direction of the base 1, and the clamping sleeve 4a is fixedly arranged at the bottom of the workbench 5 along the axis of the through hole; the extension pipe 4b is arranged on the side wall of the clamping sleeve 4a, the extension pipe 4b and the clamping sleeve 4a are connected to each other, and a feed port is arranged on the extension pipe 4b; the first switch valve 4c is arranged on the feed port; the air outlet 4d is arranged on the extension pipe 4b on one side of the first switch valve 4c; the pushing block 4f is slidably arranged inside the extension pipe 4b along the length direction of the extension pipe 4b; the driving device 4e is arranged on the extension pipe 4b, and the driving device 4e is used to drive the pushing block 4f to move in the extension pipe 4b.

[0051] Based on the above embodiments, the technical problem that the present application wants to solve is how to realize the automatic filling of the raw materials of the vertical extruder under the premise of ensuring the safety of the staff. To this end, the present application is provided with a lower pressing device 3 on the upper part of the base 1, a workbench 5 on the upper part of the lower pressing device 3, and an upper pressing device 2 on the upper part of the workbench 5. When pressing, the feeding device 4 on the workbench 5 is first required to push the molten metal raw material into the extension tube 4b, and then the lower pressing device 3 and the upper pressing device 2 will approach each other, so as to press the molten metal raw material. The working principle of the feeding device 4 is as follows: when the vertical extruder starts to run, the lower pressing device 3 is in a retracted state, and the upper part of the lower pressing device 3 will let out the first connection port between the extension tube 4b and the clamping sleeve 4a. First, it is necessary to feed, and at this time, the lower pressing device 3 will slowly rise, so that the lower pressing device 3 will block the first connection port. Then the first switch valve 4c is opened, and the first switch valve 4c will inject the molten metal raw material into the extension tube 4b. Since the side of the extension tube 4b close to the clamping sleeve 4a is blocked by the lower pressing device 3, the air in the extension tube 4b will be discharged from the air outlet 4d. It is worth noting that the air outlet 4d is set above the extension tube 4b. With the continuous injection of the molten metal raw material, the molten metal raw material in the extension tube 4b will gush out from the air outlet 4d. When filling, the air outlet 4d can be observed by machine or manually. If it is found that the molten metal raw material is about to gush out from the air outlet 4d, the filling is stopped. In this way, it can be ensured that the filling amount is neither too much nor too little. After the molten metal raw material stops being added, the lower pressing device 3 will be started and the lower pressing device 3 will gradually move downward, so that the lower pressing device 3 will give up the first connecting port, so that the molten metal in the extension tube 4b will flow into the clamping sleeve 4a, and then the driving device 4e arranged on the extension tube 4b will be started, and the driving device 4e will drive the pushing block 4f to move along the length direction of the extension tube 4b, and the pushing block 4f will push the molten metal raw material in the extension tube 4b to move toward the clamping sleeve 4a. It is worth noting that when the lower pressing device 3 opens the first connecting port, the liquid level of the molten metal in the extension tube 4b will drop. When the driving device 4e drives the push block 4f to slide in the extension tube 4b, the liquid level of the molten metal in the extension tube 4b will rise. When the molten metal has not yet flowed to the gas outlet 4d, the push block 4f will block the gas outlet 4d, thereby preventing the molten metal from flowing out of the gas outlet 4d when the push block 4f is pushed. The side of the push block 4f close to the clamping sleeve 4a is set as a curved surface, so that when the push block 4f is pushed by the driving device 4e to the end of the extension tube 4b close to the clamping sleeve 4a, the push block 4f will fit with the inner wall of the clamping sleeve 4a.In this way, when the lower pressing device 3 pushes the molten metal raw material upward, there will be no leakage. After the lower pressing device 3 drives the molten metal raw material to rise, the lower pressing device 3, the upper pressing device 2 and the through holes on the workbench 5 will form a pressing cavity, so that the molten metal raw material will be pressed and formed. Then the lower pressing device 3 drives the pressed workpiece to descend, and then the workpiece on the lower pressing device 3 can be removed. In this way, the technical requirements of automatic filling of raw materials of the vertical extruder can be achieved while ensuring the safety of the staff.

[0052] Further, such as Figure 9-10 As shown:

[0053] The driving device 4e includes a fixed seat 4e1, a first rotation driver 4e2, a gear 4e3 and a rack 4e4; the fixed seat 4e1 is fixedly arranged on the side wall of the extension tube 4b; the first rotation driver 4e2 is fixedly arranged on the fixed seat 4e1, and the output shaft of the first rotation driver 4e2 is horizontally arranged, and the axis of the output shaft of the first rotation driver 4e2 is perpendicular to the axis of the extension tube 4b; the gear 4e3 is fixedly arranged on the output end of the first rotation driver 4e2; the rack 4e4 is fixedly arranged on one side of the pushing block 4f along the axis of the extension tube 4b, and the rack 4e4 is meshed with the gear 4e3.

[0054] Based on the above embodiments, the technical problem that the present application intends to solve is how the driving device 4e drives the pushing block 4f to move. To this end, the first rotating driver 4e2 of the present application is preferably a servo motor, and a first driving opening is provided on the upper portion of the extension tube 4b on one side of the first rotating driver 4e2, and a gear 4e3 is provided on the first driving opening. Since the gear 4e3 and the rack 4e4 are meshed with each other, after the first rotating driver 4e2 is started, the first rotating driver 4e2 will drive the gear 4e3 provided on its output end to rotate, and the rotating gear 4e3 will drive the rack 4e4 to move, and the rack 4e4 will move along the length direction of the extension tube 4b, and the rack 4e4 will drive the pushing block 4e4 to move. f moves in the extension tube 4b, so that the pushing block 4f will push the molten metal in the extension tube 4b into the clamping sleeve 4a. After the lower pressing device 3 completes the pressing of the workpiece, the lower pressing device 3 will leave the clamping sleeve 4a, and the first rotary driver 4e2 will rotate in the opposite direction. At this time, the first rotary driver 4e2 will drive the gear 4e3 set on its output end to rotate, and the rotating gear 4e3 will drive the rack 4e4 to move, and then the rack 4e4 will drive the pushing block 4f to retract, thereby realizing the technical requirement that the driving device 4e can drive the pushing block 4f to move.

[0055] Further, such as Figure 6 and Fig.15 As shown:

[0056] The feeding device 4 also includes an exhaust device 4g, which includes a second switch valve 4g1, a first channel 4g2, a second channel 4g3, a first linear drive 4g4 and a shell 4g5; the second channel 4g3 is horizontally penetrated and opened on the side wall of one side of the through hole; the first channel 4g2 is opened on the workbench 5 along the height direction of the workbench 5, and the first channel 4g2 and the second channel 4g3 are connected to each other; the second switch valve 4g1 is arranged at the upper part of the first channel 4g2, and an exhaust fan is arranged on one side of the workbench 5, and the exhaust fan and the second switch valve 4g1 are connected through a first connecting pipeline; the first linear drive 4g4 is arranged on one side of the workbench 5, and the axis of the output shaft of the first linear drive 4g4 is colinear with the axis of the second channel 4g3, and the output shaft of the first linear drive 4g4 is slidably arranged in the second channel 4g3; the shell 4g5 is fixedly arranged at the upper part of the air outlet 4d.

[0057] Based on the above embodiments, the technical problem that the present application wants to solve is how to make the feeding speed faster. To this end, the first linear drive 4g4 of the present application is preferably a linear cylinder. When the molten metal begins to be injected into the extension tube 4b, the output end of the first linear drive 4g4 is in a retracted state, and the first channel 4g2 and the second channel 4g3 are interconnected. Because at this time, the lower pressing device 3, the upper pressing device 2 and the through holes on the workbench 5 form a pressing chamber. At this time, the second switch valve 4g1 will open, and the exhaust fan arranged on one side of the workbench 5 will extract the air in the pressing chamber, so that the air pressure in the pressing chamber will be less than the external pressure, so that a certain pressure difference is formed. When the lower pressing device 3 moves downward, the first connection port between the extension tube 4b and the clamping sleeve 4a will be released, so the push block 4f set in the extension tube 4b will be pushed under the action of atmospheric pressure. Since the shell 4g5 is sealed, the air pressure in the shell 4g5 is limited, and the air in the shell 4g5 will press the molten metal that is about to gush out back into the extension tube 4b. Due to the effect of the pressure difference, the push block 4f will move quickly in the extension tube 4b, so the push block 4f will quickly block the air outlet 4d, thus preventing the air in the shell 4g5 from being integrated into the molten metal. In this way, the feeding speed is increased.

[0058] Further, such as Figure 1-8 As shown:

[0059] The feeding device 4 also includes a monitoring component 4h, which includes a camera 4h1, a fixed rod 4h2 and a temperature sensor 4h3; the fixed rod 4h2 is fixedly arranged on the upper part of the workbench 5; the temperature sensor 4h3 is fixedly arranged on the side of the fixed rod 4h2 close to the air outlet 4d, and the temperature sensor 4h3 is electrically connected to the first switch valve 4c; the camera 4h1 is fixedly arranged on the outer shell 4g5 at the upper part of the air outlet 4d, and the output end of the camera 4h1 is vertically downward, and the camera 4h1 is electrically connected to the first switch valve 4c.

[0060] Based on the above embodiments, the technical problem that the present application intends to solve is how to monitor whether the molten metal in the extension tube 4b is filled when the molten metal in the extension tube 4b is filled. To this end, the present application, when the first switch valve 4c is opened, the molten metal raw material will enter the extension tube 4b, and when the molten metal in the extension tube 4b is gradually filled, the molten metal will soon gush out from the gas outlet 4d, and at this time, the temperature sensor 4h3 set on the shell 4g5 will sense the temperature at the gas outlet 4d, and when the molten metal is about to gush out from the gas outlet 4d, the temperature around the gas outlet 4d will rise rapidly. At the same time, the camera 4h1 set on the shell 4g5 will also identify the molten metal coming out of the gas outlet 4d. When the camera 4h1 identifies that the molten metal has reached the gas outlet 4d and the temperature sensor 4h3 also senses high temperature, the first switch valve 4c will be closed, so that the molten metal in the extension tube 4b is filled. In this way, the technical requirement of automatically judging whether the molten metal in the extension tube 4b has been filled is achieved when the molten metal in the extension tube 4b is filled.

[0061] Further, such as Figure 9-10 As shown:

[0062] The feeding device 4 also includes an auxiliary component 4i, which includes an extension frame 4i1 and a roller 4i2; the extension frame 4i1 is fixedly arranged on the side wall of the extension tube 4b below the driving device 4e, and a second driving opening is opened on the tube wall of the extension tube 4b on one side of the extension frame 4i1; the roller 4i2 is rotatably arranged on the extension frame 4i1, and the roller 4i2 and the gear 4e3 are symmetrically arranged about the rack 4e4, and the roller 4i2 contacts the lower part of the rack 4e4.

[0063] Based on the above embodiments, the technical problem that the present application intends to solve is how to make the rack 4e4 more balanced in force when it is driven by the gear 4e3 to move. To this end, when the first rotary driver 4e2 drives the gear 4e3 to rotate, the rack 4e4 set in the extension tube 4b is not only subjected to the force of the gear 4e3 in the length direction of the extension tube 4b, but also subjected to a downward squeezing force of the gear 4e3 on the rack 4e4. At this time, a roller 4i2 is set on the side of the rack 4e4 away from the gear 4e3, so that the roller 4i2 can provide a certain support for the rack 4e4, and the gear 4e3 can stably drive the rack 4e4 to move. In this way, the technical requirement that the force on the rack 4e4 can be more balanced when the rack 4e4 is driven by the gear 4e3 is achieved.

[0064] Further, such as Figure 9-10 As shown:

[0065] The feeding device 4 includes a limit assembly 4j, which includes a guide block 4j1 and a guide groove 4j2; at least one guide groove 4j2 is provided, and the guide groove 4j2 is opened on the inner wall of the extension tube 4b on the side of the push block 4f away from the clamping sleeve 4a, and the length direction of the guide groove 4j2 is parallel to the length direction of the extension tube 4b; the guide block 4j1 is fixedly arranged on the side wall of the rack 4e4, and the guide block 4j1 is slidably matched with the guide groove 4j2.

[0066] Based on the above embodiments, the technical problem that the present application intends to solve is how to make the rack 4e4 move more stably while preventing the rack 4e4 from falling off the gear 4e3. To this end, when the gear 4e3 drives the rack 4e4 to move, the guide block 4j1 disposed on the side wall of the rack 4e4 will slide in the guide groove 4j2, and when the side of the push block 4f close to the clamping sleeve 4a fits with the inner wall of the clamping sleeve 4a, the guide block 4j1 will move to the side of the guide groove 4j2 close to the clamping sleeve 4a. In this way, the technical requirement that the rack 4e4 can move more stably is achieved.

[0067] Further, such as Fig. 9 As shown:

[0068] The feeding device 4 also includes a sensing component, which includes a first button 4k and a second button; the first button 4k is arranged on the side of the guide groove 4j2 close to the snap-in sleeve 4a, and the first button 4k is electrically connected to the first rotation driver 4e2; the second button is arranged on the side of the extension tube 4b away from the snap-in sleeve 4a, and the second button is electrically connected to the first rotation driver 4e2.

[0069] Based on the above embodiments, the technical problem that the present application intends to solve is how to automatically identify the position state of the rack 4e4. To this end, when the rack 4e4 of the present application drives the push block 4f to move to one side of the card sleeve 4a, the guide block 4j1 on the side wall of the rack 4e4 will be located on the side of the guide groove 4j2 close to the card sleeve 4a, and the guide block 4j1 will press the first button 4k on the guide groove 4j2, so that the first rotary driver 4e2 will stop running; when the first rotary driver 4e2 drives the push block 4f to retract through the rack 4e4, the end of the rack 4e4 away from the push block 4f will gradually approach the second button, and when the rack 4e4 is fully retracted, the rack 4e4 will contact the second button, so that the second button will stop the first rotary driver 4e2. In this way, the automatic identification of the position state of the rack 4e4 is achieved.

[0070] Further, such as Figure 7-8 As shown:

[0071] It also includes a protection mechanism 6, which includes a heat absorbing plate 6a, a heat conducting rod 6b, a heat dissipation plate 6c and a protective cover 6d; the protective cover 6d is fixedly arranged on the outside of the camera 4h1; the heat conducting rod 6b is arranged to penetrate the upper part of the outer shell 4g5; the heat absorbing plate 6a is fixedly arranged on one end of the heat conducting rod 6b located inside the outer shell 4g5; the heat dissipation plate 6c is fixedly arranged on one end of the heat conducting rod 6b located outside the outer shell 4g5.

[0072] Based on the above embodiments, the technical problem that this application wants to solve is how to reduce the impact of high temperature on the camera 4h1. To this end, when the molten metal of this application is close to the air outlet 4d, it will heat the surrounding temperature, and because the shell 4g5 is airtight, the air temperature inside the shell 4g5 will rise sharply soon. At this time, the heat absorbing plate 6a set inside the shell 4g5 will absorb heat from the inside of the shell 4g5, and then the heat will be exported through the heat conducting rod 6b, and then the heat dissipation plate 6c set on the heat conducting rod 6b will dissipate the heat in time. In this way, the impact of high temperature on the camera 4h1 is reduced.

[0073] Further, such as Figure 2 As shown:

[0074] It also includes a one-way valve 7; a vent is opened at the upper part of the shell 4g5, and the one-way valve 7 is arranged on the vent.

[0075] Based on the above embodiments, the technical problem that the present application intends to solve is how to timely remove the air in the extension tube 4b when the extension tube 4b is filled after the shell 4g5 is provided. To this end, the present application only allows the air in the shell 4g5 to move to the outside of the shell 4g5 through the one-way valve 7, so that when the extension tube 4b is filled, the air in the extension tube 4b will be squeezed into the shell 4g5, and the air in the shell 4g5 will be discharged through the one-way valve 7. When the molten metal in the extension tube 4b needs to be pushed into the clamping sleeve 4a, the air in the shell 4g5 will not quickly enter the extension tube 4b due to the one-way valve 7. In this way, the technical requirement that the air in the extension tube 4b can be discharged in time when the extension tube 4b is filled is achieved.

[0076] Further, such as Figure 2 As shown:

[0077] It also includes a bracket 8; the bracket 8 is fixedly arranged on one side of the workbench 5, and the bracket 8 is fixedly connected to the extension tube 4b.

[0078] Based on the above embodiments, the technical problem that the present application intends to solve is how to provide stable support for the extension tube 4b. To this end, the bracket 8 of the present application plays a supporting role for the extension tube 4b, thus achieving the stable support function for the extension tube 4b.

[0079] The present application also provides a process method of a vertical extruder, comprising the steps of:

[0080] S1, injecting molten metal into the extension tube 4b from the feed port;

[0081] S2, exhaust the air in the extension tube 4b and the clamping sleeve 4a through the exhaust fan;

[0082] S3, the driving device 4e drives the push block 4f to move in the extension tube 4b, and injects the molten metal into the clamping sleeve 4a;

[0083] S4, the metal in the clamping sleeve 4a is pressed by driving the lower pressing device 3 and the upper pressing device 2 to approach each other to obtain a workpiece;

[0084] S5, driving the lower pressing device 3 and the upper pressing device 2 to separate from each other and taking out the workpiece in the lower pressing device 3.

[0085] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
