Description

Technical Field

[0001] The present invention relates to the technical field of automobile part processing, and particularly relates to a production device and a production process for an outer tube of a shock-absorbing component for an automobile chassis. Background Art

[0002] In the field of the automobile industry, the performance of an automobile chassis directly affects the safety, comfort and handling performance of the whole vehicle. And as a key component of the automobile chassis, the quality and performance of the shock-absorbing component play a crucial role in the shock-absorbing effect of the chassis. Among them, the production quality and efficiency of the outer tube of the shock-absorbing component are the basis for ensuring the performance of the shock-absorbing component.

[0003] Taking the production of the outer tube of a shock-absorbing component made of common metal materials as an example, there are many problems in the demolding link during the process of forming by the casting process. In the actual application of the traditional production device for the outer tube of an automobile chassis shock-absorbing component, the unreasonable demolding method seriously affects the production efficiency and product quality. When the traditional outer tube production device demolds, it mostly adopts a relatively simple structural design. Some devices only rely on manual separation of the mold and the formed outer tube. This method not only consumes a large amount of manpower and time, but also in the manual operation process, it is extremely easy to cause defects such as scratches and deformation on the surface of the outer tube due to improper operation, seriously affecting the product quality.

[0004] There are also some devices in the prior art that adopt a mechanical demolding method, but the structure is relatively simple. Usually, the outer tube is demolded by linearly pulling the mold. However, during the forming process of the outer tube, a large adhesion force will be generated between the outer tube and the mold. The simple linear demolding method is difficult to overcome this adhesion force, and the situation of the outer tube sticking to the mold often occurs, resulting in difficult demolding, and even secondary treatment of the adhered part is required, which undoubtedly further reduces the production efficiency and increases the production cost. Summary of the Invention

[0005] In order to overcome the above-mentioned drawbacks, the present invention provides a production device and a production process for an outer tube of a shock-absorbing component for an automobile chassis.

[0006] The technical solution of the present invention is: a production device for the outer tube of a shock-absorbing component for an automobile chassis, including a mounting plate, guide rods, a pushing block, a concave mold, a cylinder, a convex mold and a cooling component. Guide rods are symmetrically arranged on both sides of the mounting plate. A pushing block is slidably connected between the guide rods. A convex mold is symmetrically and slidably connected to the pushing block. The right side of the convex mold is a cylinder, and the left end is a support rod, and the two are integrally formed. A concave mold is arranged between the right ends of the guide rods. Grooves adapted to the convex mold are opened on both inner sides of the concave mold. A cylinder is arranged on the left side of the mounting plate, and the telescopic rod of the cylinder is connected to the pushing block. A cooling component is arranged on the convex mold; it also includes a sleeve rod, a support ring, a driving component and a return spring. A sleeve rod is rotatably connected to the outer side of the support rod of the convex mold. A driving component is arranged between the pushing block and the sleeve rod. Support rings are symmetrically arranged on the pushing block. A ring sleeve is arranged on the outer side of the support ring. A return spring is sleeved on the outer side of the support rod of the convex mold, and the two ends of the return spring are respectively connected to the ring sleeve and the sleeve rod.

[0007] Further, the driving component includes a guide rail, a rack, a gear and a hinge rod. A guide rail is connected to the left inner wall of the pushing block. The sleeve rod is slidably connected to the guide rail. Racks are symmetrically and slidably connected to the guide rail. A gear meshing with the rack is rotatably connected to the support ring. The gear is connected to the support rod of the convex mold through a spline. A hinge rod is rotatably connected between the lower end of the sleeve rod and the corresponding rack.

[0008] Further, the cooling component includes a liquid inlet valve and a liquid outlet valve. The upper and lower sides of the left end of the convex mold are respectively connected with a liquid inlet valve and a liquid outlet valve. The liquid inlet valve is located above, and the liquid outlet valve is located below. A spiral chamber is opened inside the convex mold. The two ends of the spiral chamber are respectively a liquid inlet end and a liquid outlet end. The liquid inlet end communicates with the liquid inlet valve, and the liquid outlet end communicates with the liquid outlet valve.

[0009] Further, it also includes a top rod, a clamping block, a buffer spring and a clamping spring. Top rods are symmetrically and slidably connected to both the upper and lower sides inside the pushing block. The right end face of the top rod is of an inclined structure, and a buffer spring is connected between the top rod and the inside of the pushing block. Clamping blocks are slidably connected to the left side face of the concave mold at positions aligned with the top rods. Each two clamping blocks are respectively located on the upper and lower sides of the groove. A clamping spring is connected between the clamping block and the concave mold, and an inclined surface is arranged in the middle of the clamping block, and the inclined surface cooperates with the inclined structure of the top rod.

[0010] Further, it also includes a cylinder body, a first air pump, a conical rod and a tension spring. Cylinder bodies are symmetrically connected to the right side face of the concave mold. A conical rod is slidably connected inside the cylinder body. The two conical rods respectively penetrate through the two grooves of the concave mold. A tension spring is connected between the conical rod and the inside of the cylinder body. A first air pump is installed on the outer side of the cylinder body.

[0011] Furthermore, it also includes a second air pump, which is respectively installed on the front and rear side walls of the push block. An air intake channel is opened on the left side of the push block. The two second air pumps are interconnected with the air intake channel, and the cavity between the push block and the concave mold is interconnected with the air intake channel.

[0012] Furthermore, it also includes a support block, a slide rail, a shock-absorbing belt, a tension spring, an inclined frame and a pulley. The support block is symmetrically connected to the right side of the lower part of the mounting plate, and the support blocks are also connected to the two side walls of the lower part of the concave mold. Each support block is provided with a slide rail with a sliding connection. The lower ends of the four slide rails are commonly connected to a shock-absorbing belt. A tension spring is connected between the upper ends of the two slide rails on the left and the mounting plate, and a tension spring is also connected between the upper ends of the two slide rails on the right and the concave mold. The top of the shock-absorbing belt is symmetrically connected to the inclined frame, and the lower side of the push block is symmetrically and rotationally connected to the pulley, and the pulley and the inclined frame form a contact and matching relationship.

[0013] Furthermore, the shock absorbing belt is inclined with the left side lower and the right side higher.

[0014] Furthermore, it also includes a positioning rod, and the four corners of the left side wall of the concave mold are connected to the positioning rod. Positioning grooves are respectively opened on the right side wall of the push block at positions corresponding to the positions of the positioning rods, and the positioning rods are plugged into the positioning grooves.

[0015] A process for producing an outer tube of a shock-absorbing component for an automobile chassis, using the above-mentioned equipment for producing an outer tube of a shock-absorbing component for an automobile chassis, comprises the following steps: S1: After ensuring that the injection mechanism is connected to the concave mold, connect the inlet valve and the outlet valve to the coolant pipeline, and start the cooling mechanism. The coolant is injected into the spiral chamber from the inlet valve, and then flows out from the outlet valve back to the cooling mechanism to form a cycle; S2: The cylinder starts to drive the push block to move, so that the convex mold moves to the right and docks with the concave mold. The rack is converted into the rotation of the convex mold through the gear. S3: When the push block completely wraps around the convex mold, the injection mechanism injects the molten metal into the cavity between the two molds, and at the same time supplies coolant to the spiral chamber to help the outer tube part to cool and form quickly; S4: After molding, the cylinder drives the assembly to move left and reset. The convex mold pops outward due to the action of the reset spring, and realizes reverse rotation with the help of the interaction between the rack and the gear, completing the initial demoulding; S5: In the demoulding stage, the first air pump and the second air pump are activated. The second air pump inflates the air inlet channel, and the air enters the cavity between the push block and the concave mold, and the outer tube product is pushed out in cooperation with the ejection action of the convex mold. The first air pump draws air into the cylinder body, guides the air to be discharged along the edge of the groove, and helps the finished product to be separated from the groove. S6: After demoulding, the finished outer tube falls on the shock-absorbing belt, is buffered by the tension spring and slides down the inclined surface to complete the collection work.

[0016] The beneficial effects are as follows: 1. Through the coordinated operation of the reset spring, rack and gear, etc., the convex mold can rotate and pop outwards during demolding, effectively ensuring the smooth demolding of the outer tube finished product; at the same time, the first air pump and the conical rod assist the outer tube finished product to demold from the groove, and the second air pump cooperates with the ejection of the convex mold to remove the adhered outer tube finished product. The combined action of multiple methods greatly improves the demolding efficiency and success rate, facilitating the subsequent processing of the operator.

[0017] 2. Through the precise movement of the pushing block and the convex mold driven by the cylinder, combined with the groove design of the concave mold, the construction of the cavity can be quickly completed, and the molten metal or alloy liquid can be efficiently injected with the help of the injection equipment, realizing the rapid forming of the outer tube and greatly improving the production efficiency.

[0018] 3. The spiral chamber and the coolant circulation structure of the cooling component can continuously cool the outer tube parts during the forming process, ensuring the forming quality of the outer tube and improving the product performance and stability.

[0019] 4. The buffer structure composed of the support block, slide rail, shock-absorbing belt and tension spring can effectively buffer the impact force when the outer tube finished product drops, avoid damage to the product caused by dropping, and ensure the product quality.

Specific embodiments

[0034] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1: A production device for the outer tube of a shock-absorbing component for an automobile chassis, as Figures 1-6As shown in the figure, it includes a mounting plate 1, guide rods 101, a pushing block 102, a concave mold 103, a cylinder 104, a convex mold 105, a sleeve rod 201, a guide rail 202, a rack 203, a support ring 204, a gear 205, a hinge rod 206, a return spring 207 and a cooling component. On both the front and rear sides of the mounting plate 1, the guide rods 101 are symmetrically and penetratingly connected up and down. A pushing block 102 is slidably connected between the four guide rods 101. A convex mold 105 is slidably connected to the front and rear of the pushing block 102. The right part of the convex mold 105 is a cylinder, and a support rod is connected to the left end of the cylinder, and the two form an integral structure. A concave mold 103 is connected between the right ends of the four guide rods 101. Grooves are provided on the front and rear sides inside the concave mold 103, and the grooves are adapted to the cylinder of the convex mold 105. When the two are sleeved, the cavity between the groove and the convex mold 105 is the forming space for the outer tube finished product 109. The surface treatment of the groove of the concave mold 103 uses a material or process with a low friction coefficient to reduce the friction between the outer tube finished product 109 and the groove. The surface of the convex mold 105 is treated with hard chromium plating, which significantly improves the surface hardness and smoothness. Moreover, the inner groove of the pushing block 102 in contact with the convex mold 105 is nitrided, which can not only improve the surface hardness but also reduce the friction coefficient, making the inner groove of the pushing block 102 not easily adhere to the outer tube finished product 109. A connection port is connected to the right end of the concave mold 103, and the connection port communicates with the groove for connecting an external injection device to inject molten metal or alloy liquid into the cavity. A cylinder 104 is installed on the left side of the mounting plate 1. The telescopic rod of the cylinder 104 penetrates the mounting plate 1 and is connected to the pushing block 102. Sleeve rods 201 are rotatably connected to the outer sides of the support rods of the convex mold 105. A guide rail 202 is connected to the left inner wall of the pushing block 102. The sleeve rods 201 are slidably connected to the guide rail 202. Racks 203 are slidably connected to the front and rear of the guide rail 202 symmetrically. Support rings 204 are welded symmetrically to the front and rear positions above the guide rail 202 on the pushing block 102. A gear 205 meshing with the rack 203 is rotatably connected to the support rings 204. The gear 205 is connected to the support rod of the convex mold 105 by a spline connection, so that the rotation of the gear 205 can drive the rotation of the convex mold 105, and the movement of the convex mold 105 will not affect the gear 205. Hinge rods 206 are rotatably connected to the lower ends of the sleeve rods 201 respectively, and the right ends of the hinge rods 206 are rotatably connected to the corresponding racks 203 respectively. A collar is sleeved outside the support ring 204, and the collar is located outside the support rod of the convex mold 105. A return spring 207 is sleeved on the outer side of the support rod of the convex mold 105. The left and right ends of the return spring 207 are connected to the collar and the sleeve rod 201 respectively, and are used to provide a return force for the convex mold 105. A cooling component is provided on the convex mold 105.

[0036] As Figure 3As shown, the cooling component includes a liquid inlet valve 107 and a liquid outlet valve 108. The upper and lower sides of the left end of the convex mold 105 are respectively connected to the liquid inlet valve 107 and the liquid outlet valve 108. The liquid inlet valve 107 is located above, and the liquid outlet valve 108 is located below. A spiral chamber 106 is provided inside the convex mold 105. The two ends of the spiral chamber 106 are respectively a liquid inlet end and a liquid outlet end. The liquid inlet end communicates with the liquid inlet valve 107, and the liquid outlet end communicates with the liquid outlet valve 108, forming a circulating flow structure with one inlet and one outlet.

[0037] When manufacturing and forming the outer tube, first connect the injection mechanism to the concave mold 103 through the connection port, then connect the liquid inlet valve 107 and the liquid outlet valve 108 to the coolant pipeline of the cooling mechanism. The cooling mechanism injects the coolant into the spiral chamber 106 through the coolant pipeline and the liquid inlet valve 107. After the coolant flows inside the spiral chamber 106, it flows back to the liquid outlet valve 108 from the other end, and is discharged to the cooling mechanism through the liquid outlet valve 108 for cooling, thus realizing the circulating flow of the coolant. After the preparation work is completed, start the cylinder 104. The telescopic rod of the cylinder 104 extends, driving the pushing block 102 and the convex mold 105 to move to the right along the guide rod 101. During this process, the convex mold 105 gradually aligns with the groove of the concave mold 103 and then inserts into the groove. When the convex mold 105 is in full contact with the groove, the convex mold 105 cannot move further, while the telescopic rod of the cylinder 104 continues to extend, driving the pushing block 102 to continue moving to the right. At this time, components such as the support ring 204, the gear 205, the guide rail 202, and the rack 203 also move to the right, and the return spring 207 is stretched. The movement of the rack 203 drives the articulated rod 206 to rotate. Since the articulated rod 206 cannot move, this causes the rack 203 to move outward by itself, and then the rack 203 drives the gear 205 to rotate. Because the gear 205 is spline-connected to the support rod of the concave mold 103, the gear 205 can drive the convex mold 105 to rotate. When the pushing block 102 completely sleeves outside the convex mold 105, inject the molten metal or alloy into the cavity between the groove, the convex mold 105, and the pushing block 102 at high pressure and high speed through the injection mechanism, thus forming the outer tube part. During the entire forming process, continuously inject the coolant into the spiral chamber 106 to cool and form the outer tube part. After the outer tube is formed, control the cylinder 104 to run in reverse, and the telescopic rod of the cylinder 104 shortens, driving the pushing block 102 and the convex mold 105 to move to the left to reset. When the convex mold 105 is separated from the groove by a certain distance, the return spring 207 rebounds and resets, causing the convex mold 105 to pop out to the right on the basis of the pushing block 102.Under the reverse rotation action of the articulated rod 206, the rack 203 moves inward to reset, drives the convex mold 105 to rotate in the reverse direction through the gear 205. The rotation and outward springing action of the convex mold 105 can ensure the smooth demolding of the convex mold 105 and the outer tube finished product 109. Since the inner groove of the pushing block 102 is nitrided and the matching precision between the inner groove of the pushing block 102 and the convex mold 105 is strictly controlled, it is ensured that under normal working conditions, the pushing block 102 will not cause adhesion to the outer tube finished product 109. When the convex mold 105 is separated from the outer tube finished product 109, the outer tube finished product 109 is also separated from the pushing block 102. At the same time, the rotation of the convex mold 105 generates a torsional force on the outer tube finished product 109, destroying the tightly fitting state formed between the outer tube finished product 109 and the concave mold 103 due to the forming process, changing the distribution of the adhesion force, and realizing the separation of the outer tube finished product 109 and the concave mold 103, facilitating the operator to unload the outer tube finished product 109. According to the above operation process, the production of the outer tube can be continued.

[0038] Embodiment 2: On the basis of Embodiment 1, as Figures 7-9 shown, it further includes a ejector rod 301, a clamping block 302, a buffer spring 303 and a clamping spring 305. The ejector rods 301 are symmetrically slidably connected to the upper and lower sides inside the pushing block 102 in the front and rear directions. The right end surface of the ejector rod 301 is of an inclined structure, and a buffer spring 303 is connected between the ejector rod 301 and the inside of the pushing block 102. Clamping blocks 302 are slidably connected to the left side surface of the concave mold 103 at positions aligned with the ejector rods 301. Every two clamping blocks 302 are respectively located on the upper and lower sides of the groove, and their main function is to clamp the outer tube finished product 109. A clamping spring 305 is connected between the clamping block 302 and the concave mold 103, and an inclined surface 304 is provided in the middle of the clamping block 302. The inclined surface 304 cooperates with the inclined structure of the ejector rod 301 to realize the automatic opening and clamping actions of the clamping block 302.

[0039] When the pushing block 102 drives the convex mold 105 to move to the right, it will synchronously drive the ejector rod 301 to move to the right. During this process, the inclined structure of the ejector rod 301 will first contact the inclined surface 304 of the clamping block 302. Through the mutual cooperation of the two inclined surfaces 304, the clamping block 302 will move outward, resulting in the compression of the clamping spring 305. When the convex mold 105 is docked with the concave mold 103 in place, the pushing block 102 will continue to move and sleeve outside the convex mold 105. At this time, since the ejector rod 301 and the inclined surface 304 of the clamping block 302 are already in full contact, the ejector rod 301 cannot continue to move to the right, and the continuous movement of the pushing block 102 will compress the buffer spring 303. The buffer spring 303 plays a buffering role here and provides a certain space for the subsequent movement of the pushing block 102. When the outer tube is formed, the pushing block 102 drives the convex mold 105 to move to the left. During this process, the outer tube finished product 109 cooperates with the convex mold 105, and the outer tube finished product 109 will be taken out to the left by a part. At this time, the buffer spring 303 resets, and the ejector rod 301 moves to the left with the pushing block 102, and then disengages from the contact with the inclined surface 304. Subsequently, the clamping spring 305 rebounds and resets, driving the clamping block 302 to move inward. The clamping block 302 will clamp the outer tube finished product 109 to play a limiting role to prevent the outer tube finished product 109 from continuing to move with the convex mold 105. When the convex mold 105 is completely separated from the outer tube finished product 109, because the size of the outer tube finished product 109 is larger than that of the convex mold 105, when the outer tube finished product 109 is suspended only by the clamping force of the clamping block 302, since the outer tube finished product 109 is taken out by the convex mold 105 by a part, the center of gravity of the outer tube finished product 109 is not in the part that fits the groove. Once the convex mold 105 is separated, the component of the gravity force on the outer tube finished product 109 will generate a rotational moment around the clamping point. This moment will gradually cause a gap to appear between the fitting surface of the outer tube finished product 109 and the groove. As the gap increases, the outer tube finished product 109 will gradually tilt under the action of gravity and finally fall downward from the groove, facilitating the operator to collect it.

[0040] As Figure 8 , Figures 10-11 shown, it further includes a cylinder body 401, a first air pump 402, a tapered rod 403 and a tension spring 404. The front and rear sides of the right side of the concave mold 103 are symmetrically connected with the cylinder body 401. A tapered rod 403 is slidably connected inside the cylinder body 401. The two tapered rods 403 respectively penetrate through the two grooves of the concave mold 103. A tension spring 404 is connected between the tapered rod 403 and the inside of the cylinder body 401. The first air pump 402 is installed on the outside of the cylinder body 401 through bolts.

[0041] When the convex mold 105 moves to the right and inserts into the groove of the concave mold 103, the convex mold 105 will squeeze the tapered rod 403, causing it to move to the right, and the tension spring 404 will be stretched accordingly. At this time, a closed state is formed between the cylinder body 401 and the groove, which can effectively prevent the molten liquid from entering the inside of the cylinder body 401 when injecting the molten liquid into the cavity between the groove and the convex mold 105. After the outer tube is formed, the convex mold 105 moves to the left to reset. At this time, the first air pump 402 is started to pump external air into the cylinder body 401. Under the reset action of the tension spring 404, the tapered rod 403 moves to the left to open the channel, and the gas enters the groove. Due to the special tapered structure of the tapered rod 403, it plays a good guiding role. The gas enters the bottom of the groove from the gap between the tapered rod 403 and the groove, and then diffuses around at the bottom of the groove. And because the gap between the outer tube finished product 109 and the groove wall is small, the gas will preferentially flow along this gap during the diffusion process, forming an air flow around the circumference of the outer tube finished product 109. This air flow will form an air film between the outer tube finished product 109 and the groove wall, reducing the friction between the two. At the same time, the pressure of the air flow will also generate an outward thrust acting on the outer tube finished product 109. The gas accumulates in the gap between the groove wall and the outer tube finished product 109 and generates a pressure difference to overcome the adhesion force generated during forming and the possible small friction force between the outer tube finished product 109 and the groove wall, thereby assisting the outer tube finished product 109 to smoothly separate from the concave mold 103. After the demolding is completed, the first air pump 402 is closed.

[0042] As Figure 1 and Figure 5 shown, it further includes a second air pump 501. The second air pumps 501 are respectively installed on the front and rear side walls of the pushing block 102 through bolts. An air inlet channel 502 is opened on the left side inside the pushing block 102. The two second air pumps 501 communicate with the air inlet channel 502, and the chamber between the pushing block 102 and the concave mold 103 communicates with the air inlet channel 502.

[0043] After the outer tube is formed, the pushing block 102 drives the convex mold 105 to move to the left to separate from the concave mold 103. At the same time, the second air pump 501 is started to continuously inflate the air inlet channel 502. The gas enters the chamber between the pushing block 102 and the concave mold 103 through the air inlet channel 502. The gas will penetrate from the gaps between the outer tube finished product 109, the convex mold 105 and the inner groove of the pushing block 102, generating an outward thrust on the inner side of the adhesion surface. During the process of the convex mold 105 moving to the left to reset, under the action of the reset spring 207, the convex mold 105 will pop out to the right. A certain stretching and torsional force will be generated at the adhesion parts of the convex mold 105 and the pushing block 102 with the outer tube finished product 109. The thrust action of the gas will enhance the strength and speed of the convex mold 105 popping out, realizing the effective demolding of the outer tube finished product 109. After the demolding is completed, the second air pump 501 is closed.

[0044] As Figure 12 and Figure 13 shown, it further includes support blocks 601, slide rails 602, shock-absorbing belts 603, tension springs 604, inclined frames 605 and pulleys 606. On the right side of the lower part of the mounting plate 1, support blocks 601 are symmetrically connected by bolts in the front and back. On the front and back side walls of the lower part of the concave die 103, support blocks 601 are also connected in the same way. Slide rails 602 which are slidably connected are arranged on each support block 601. The lower ends of the four slide rails 602 are jointly connected with an obliquely arranged shock-absorbing belt 603. The shock-absorbing belt 603 is in an inclined state with the left side lower and the right side higher, facilitating the natural sliding of the finished pipe fittings. The shock-absorbing belt 603 is located directly below the entire device. Tension springs 604 are connected between the upper ends of the two slide rails 602 on the left side and the mounting plate 1, and tension springs 604 are also connected between the upper ends of the two slide rails 602 on the right side and the concave die 103. The front and back of the top of the shock-absorbing belt 603 are symmetrically connected with inclined frames 605. Pulleys 606 are symmetrically rotatably connected to the lower side of the pushing block 102. The pulleys 606 and the inclined frames 605 form a contact and cooperation relationship.

[0045] When the pushing block 102 drives the convex die 105 to move and sleeve with the concave die 103, the pulleys 606 move synchronously with the pushing block 102. During this process, the pulleys 606 contact the inclined surface 304 of the inclined frame 605, thereby exerting an extrusion force on the inclined frame 605 and the shock-absorbing belt 603, causing the inclined frame 605 and the shock-absorbing belt 603 to move downward, and at the same time driving the slide rails 602 to slide downward along the support blocks 601, and the tension springs 604 are stretched. During the processing of the outer pipe, the shock-absorbing belt 603 maintains this lower height. After the outer pipe is formed, the pushing block 102 drives the convex die 105 to move to the left and separate from the concave die 103, and the pulleys 606 also move to the left accordingly. At this time, the demolded outer pipe finished product 109 will fall downward onto the shock-absorbing belt 603, and the setting of the tension springs 604 can play an effective buffering role for the outer pipe finished product 109, avoiding damage to the outer pipe finished product 109 due to the impact of falling. The outer pipe finished product 109 will smoothly slide out to the left along the inclined surface 304 of the shock-absorbing belt 603, facilitating the operator to collect the outer pipe finished product 109. After the pushing block 102 drives the convex die 105 and the pulleys 606 to move to the left and reset as a whole, the pulleys 606 no longer exert pressure on the inclined frame 605, and the shock-absorbing belt 603, the inclined frame 605 and the slide rails 602 move upward as a whole and return to the initial height.

[0046] As Figure 1 and Figure 2As shown in the figure, it further includes a positioning rod 7. The positioning rod 7 is connected to the four corners of the left side wall of the concave mold 103. Positioning grooves are respectively provided at the positions corresponding to the positioning rod 7 on the right side wall of the pushing block 102. During the process of the pushing block 102 driving the convex mold 105 to move to the right to dock with the concave mold 103, through the insertion and cooperation of the positioning rod 7 and the positioning groove, it can play a role in accurately positioning the pushing block 102 and the concave mold 103, effectively ensuring the accuracy when the two are docked, and improving the quality and stability of the outer tube production.

[0047] A production process for the outer tube of a shock-absorbing component for an automotive chassis, using the above-mentioned production equipment for the outer tube of a shock-absorbing component for an automotive chassis, includes the following steps: S1: Connection and startup of the cooling system First, ensure that the injection mechanism is firmly connected to the concave mold 103 through the connection port. Then, connect the liquid inlet valve 107 and the liquid outlet valve 108 to the coolant pipeline respectively, and start the cooling mechanism so that the coolant can be injected into the spiral chamber 106 of the convex mold 105 from the liquid inlet valve 107, and then flow out from the liquid outlet valve 108 and return to the cooling mechanism to form an effective coolant circulation.

[0048] S2: Mold docking and rotation preparation Start the cylinder 104, so that the telescopic rod of the cylinder 104 extends. The pushing block 102 moves accordingly and drives the convex mold 105 to move to the right along the guide rod 101 until it docks with the groove of the concave mold 103. Subsequently, the telescopic rod of the cylinder 104 continues to extend, and the pushing block 102 moves further to the right, driving components such as the gear 205, the guide rail 202, and the rack 203 to move synchronously to the right. During this process, the movement of the rack 203 is converted into the rotation of the convex mold 105 through the gear 205.

[0049] S3: High-pressure injection molding When the pushing block 102 completely wraps the convex mold 105, start the injection mechanism, and inject molten metal or alloy into the cavity between the concave mold 103 and the convex mold 105 through the connection port at high pressure and high speed. While injecting the material, continuously supply coolant to the spiral chamber 106 to cool the outer tube part being formed and promote its molding.

[0050] S4: Reset and preliminary demolding After the outer tube is formed, control the cylinder 104 to operate in the reverse direction, shorten the telescopic rod of the cylinder 104, and drive the pushing block 102 and the convex mold 105 to move leftward to reset. During this process, the convex mold 105 pops outwards due to the action of the reset spring 207, and realizes reverse rotation with the help of the interaction between the rack 203 and the gear 205 to assist in completing the demolding process.

[0051] S5: Pneumatic-assisted demolding During the demolding stage, the first air pump 402 and the second air pump 501 are synchronously activated. The second air pump 501 inflates the air inlet passage 502, and the gas enters the chamber between the pushing block 102 and the concave mold 103, and cooperates with the ejection action of the convex mold 105 to push out the adhered outer tube finished product 109; the first air pump 402 extracts the external air and sends it into the interior of the cylinder body 401, prompting the conical rod 403 to move leftward, and the gas flows into the groove and is discharged along the edge of the groove under the guidance of the conical rod 403, assisting the outer tube finished product 109 to disengage from the groove.

[0052] S6: Finished product collection The demolded outer tube finished product 109 falls on the shock-absorbing belt 603, is buffered by the tension spring 604, and slides down along the inclined surface 304 of the shock-absorbing belt 603, finally completing the collection work of the pipe fitting finished product.

[0053] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
