Description

TECHNICAL FIELD

[0001] The utility model relates to mould assembly technical field, concretely relates to a kind of assembly structure of extrusion forming mould for vehicle shock support. BACKGROUND

[0002] Vehicle shock support as the key component of automobile chassis system plays a vital role in safeguarding vehicle driving performance. Its core function is to effectively weaken the vibration and impact suffered during vehicle driving, and thus create a more stable and comfortable driving experience for the driver and passengers. Shock support is generally installed inside the vehicle suspension system and works in conjunction with the shock absorber to efficiently absorb and reasonably disperse the impact force from the road, protecting other components of the vehicle from unnecessary damage.

[0003] As for the current application status of lower mould of vehicle shock support, positioning pin is generally used directly fixed. In actual assembly process, the lower mould needs to be accurately aligned first, and then further fixed operation can be carried out. However, since the lower mould itself has a certain weight, it is difficult for the operator to place it stably on the base to carry out alignment work, which undoubtedly adds great difficulty to the placement of positioning pin, resulting in complicated assembly process and time-consuming. Moreover, after the mould completes the forming operation, the existing fixing mode limits the disassembly of the lower mould for replacement and maintenance, which seriously affects the production efficiency and normal operation of the equipment, and thus needs to be improved. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model provides an assembly structure of extrusion forming mould for vehicle shock support, which solves the problems raised in the background art.

[0005] The utility model solves the above technical problems by the following scheme:

[0006] An assembly structure of extrusion forming mould for vehicle shock support, comprising a bottom plate, a support seat, a lower mould and an upper mould, the support seat and a guide rod are installed on the bottom plate, the lower mould and the upper mould are arranged on the bottom plate;

[0007] A assembly groove is formed in the lower mould;

[0008] A cavity is formed in the support seat, a fixed pin is arranged in the cavity, a connecting pipe is embedded in the cavity, a fixed ring is installed on the connecting pipe, and a screw rod is installed in the fixed ring through screw thread.

[0009] On the basis of the above technical scheme, the utility model can also be improved as follows.

[0010] Further, a top plate is installed on the upper mould, and the top plate is slidingly sleeved on the guide rod.

[0011] The beneficial effects of the above further scheme are:

[0012] The sliding fit of the top plate and the guide rod provides accurate guidance for the up-down movement of the upper mold. During the extrusion molding process, the upper mold can stably move downward along the guide rod, ensuring precise docking with the lower mold and improving the precision of extrusion molding.

[0013] Further, the bottom end face of the lower mold is installed with a guide block which is slidingly sleeved in the support seat.

[0014] The beneficial effects of the above further scheme are:

[0015] The sliding connection of the guide block and the support seat provides additional support and guidance for the lower mold. When assembling the mold, personnel can directly place the lower mold in the support seat for left-right movement, and then perform alignment work after placement.

[0016] Further, a second piston is installed on the screw and slidingly sleeved in the connecting pipe.

[0017] The beneficial effects of the above further scheme are:

[0018] The cooperation of the second piston with the screw and the sliding in the connecting pipe forms a hydraulic transmission structure. When the screw is rotated, the second piston moves correspondingly in the connecting pipe, thereby changing the pressure of the hydraulic oil in the connecting pipe. This structure can control the fixed pin, and through the transmission of hydraulic oil, the rotational motion of the screw is converted into the linear motion of the fixed pin, providing adjustable power source for the extension and retraction of the fixed pin.

[0019] Further, the cavity and the connecting pipe are filled with hydraulic oil.

[0020] The beneficial effects of the above further scheme are:

[0021] Hydraulic oil, as a good force transmission medium, plays a key connection and transmission role in the cavity and the connecting pipe. It can uniformly transmit the pressure generated by the second piston to the first piston, thereby pushing the fixed pin to act. The incompressibility of hydraulic oil ensures the efficiency and accuracy of force transmission, so that the fixed pin can stably extend or retract, realizing reliable fixing and loosening of the assembly groove.

[0022] Further, a handle frame is installed on the screw, and a spring washer is sleeved on the screw.

[0023] The beneficial effects of the above further scheme are:

[0024] The grip bracket provides operators with a convenient and comfortable operating position. When adjusting the screw, operators can easily turn it by holding the grip bracket, improving ease of operation and efficiency. The spring washer plays a role in preventing loosening. During mold operation, vibrations and impacts occur, and the spring washer maintains preload on the screw during these vibrations, preventing it from loosening and ensuring the stability and reliability of the entire hydraulic adjustment system, allowing the retaining pin to remain in the set position.

[0025] Furthermore, each of the fixing pins is slidably sleeved in the assembly groove, and the bottom end face of the fixing pin is fitted with a first piston, which is slidably sleeved in the cavity.

[0026] The beneficial effects of adopting the above-mentioned further solutions are:

[0027] The sliding fit between the fixing pin and the assembly slot, along with the connection between the first piston and the hydraulic oil in the cavity, effectively secures and releases the components assembled within the assembly slot. When the hydraulic oil pressure in the cavity changes, the first piston drives the fixing pin to slide up and down within the assembly slot. During the assembly of the lower mold, the fixing pin extends to fix and limit the lower mold, preventing displacement during extrusion and ensuring the molding accuracy of the product. When it is necessary to remove or replace components, the hydraulic oil pressure is changed by adjusting the screw, causing the fixing pin to retract, facilitating quick and easy disassembly of the components. This greatly improves the flexibility of mold use and ease of maintenance. Furthermore, when the fixing pin is retracted into the cavity, personnel can directly place the lower mold, which has a certain weight, on the support base for alignment work, avoiding the need for operators to repeatedly move the lower mold for alignment and assembly operations.

[0028] This utility model provides an assembly structure for an extrusion molding die for a vehicle shock absorber bracket. It has the following advantages:

[0029] The guide block of the lower mold is slidably connected to the support base, providing additional support and guidance for the lower mold, which facilitates alignment after placement; and when the fixing pin is retracted, it is convenient for personnel to place the lower mold on the support base for alignment, avoiding the problem of frequent handling due to the heavy weight of the lower mold.

[0030] The hydraulic transmission structure, consisting of components such as the screw, the second piston, and hydraulic oil, can control the extension and retraction of the fixing pin by rotating the screw, converting the rotational motion of the screw into the linear motion of the fixing pin. This provides an adjustable power source for the movement of the fixing pin, enabling the effective fixing and release of components assembled in the assembly slot.

[0031] Hydraulic oil, as the force transmission medium, utilizes its incompressibility to ensure the efficiency and accuracy of force transmission, enabling the fixing pin to extend or retract stably, thus achieving reliable fixing and loosening of the assembly slot and ensuring the stability of the entire system.

[0032] The grip bracket provides operators with a convenient and comfortable operating position, making it easy to rotate the screw and improving the convenience and efficiency of operation; the spring washer plays an anti-loosening role, maintaining the preload on the screw when the mold is vibrating and impacted during operation, preventing the screw from loosening, ensuring the stability and reliability of the hydraulic adjustment system, and ensuring that the fixing pin can be kept in the set position continuously.

[0033] By adjusting the screw to change the hydraulic oil pressure, the fixing pin can be retracted, making it easy and quick to disassemble the parts, greatly improving the flexibility of mold use and the convenience of maintenance. Attached Figure Description

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0044] Example 1

[0045] An assembly structure for an extrusion molding die for a vehicle shock absorber bracket includes a base plate 1, a support seat 2, a lower die 3 and an upper die 401. The support seat 2 and a guide rod 101 are installed on the base plate 1, and the lower die 3 and the upper die 401 are provided on the base plate 1.

[0046] The lower mold 3 has an assembly slot 301 inside;

[0047] The support base 2 has a cavity 208, a fixing pin 202 is provided in the cavity 208, a connecting pipe 201 is embedded and fixed in the cavity 208, a fixing ring 206 is installed on the connecting pipe 201, and a screw 203 is installed in the fixing ring 206 by thread.

[0048] A top plate 4 is mounted on the upper mold 401, and the top plate 4 is slidably sleeved on the guide rod 101. The sliding fit between the top plate 4 and the guide rod 101 provides precise guidance for the up-and-down movement of the upper mold 401. During the extrusion molding process, the upper mold 401 can move stably downward along the guide rod 101, ensuring precise docking with the lower mold 3 and improving the accuracy of extrusion molding.

[0049] A guide block 302 is installed on the bottom end face of the lower mold 3. The guide block 302 is slidably sleeved in the support base 2. The sliding connection between the guide block 302 and the support base 2 provides additional support and guidance for the lower mold 3. When assembling the mold, the operator can place the lower mold 3 directly in the support base 2 and move it left and right to perform alignment work after placement.

[0050] A second piston 209 is fitted onto the screw 203 and slidably sleeved within the connecting pipe 201. The cooperation between the second piston 209 and the screw 203, as well as its sliding within the connecting pipe 201, constitutes a hydraulic transmission structure. When the screw 203 is rotated, the second piston 209 moves accordingly within the connecting pipe 201, thereby generating pressure changes in the hydraulic oil within the connecting pipe 201. This structure enables control of the fixed pin 202, converting the rotational motion of the screw 203 into the linear motion of the fixed pin 202 through the transmission of hydraulic oil, providing an adjustable power source for the extension and retraction of the fixed pin 202.

[0051] The cavity 208 and connecting pipe 201 are filled with hydraulic oil. As an excellent force transmission medium, the hydraulic oil plays a crucial role in connecting and transmitting force within the cavity 208 and connecting pipe 201. It can evenly transmit the pressure generated by the second piston 209 to the first piston 207, thereby driving the fixing pin 202 to move. The incompressibility of the hydraulic oil ensures the efficiency and accuracy of force transmission, allowing the fixing pin 202 to extend or retract stably, achieving reliable fixing and loosening of the assembly slot 301.

[0052] Example 2

[0053] To allow for removal, replacement, or maintenance after assembly, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0054] A handle 204 is mounted on the screw 203, and a spring washer 205 is fitted onto the screw 203. The handle 204 provides the operator with a convenient and comfortable operating position. When adjusting the screw 203, the operator can easily rotate the screw 203 by holding the handle 204, improving the convenience and efficiency of operation. The spring washer 205 plays a role in preventing loosening. During the mold's operation, a certain amount of vibration and impact will occur. The spring washer 205 can maintain the preload on the screw 203 during vibration, preventing the screw 203 from loosening due to vibration, ensuring the stability and reliability of the entire hydraulic adjustment system, and allowing the fixing pin 202 to remain in the set position continuously.

[0055] The fixing pins 202 are slidably sleeved in the assembly groove 301. A first piston 207 is fitted to the bottom end of each fixing pin 202 and slidably sleeved within the cavity 208. The sliding engagement between the fixing pins 202 and the assembly groove 301, along with the connection between the first piston 207 and the hydraulic oil within the cavity 208, effectively fixes and releases the components assembled within the assembly groove 301. When the hydraulic oil pressure within the cavity 208 changes, the first piston 207 causes the fixing pins 202 to slide up and down within the assembly groove 301. During the assembly of the lower mold 3, the fixing pins 202 extend to fix and limit the lower mold 3, preventing displacement during extrusion and ensuring the product's molding accuracy. When it is necessary to remove or replace parts, the hydraulic oil pressure can be changed by adjusting the screw 203, causing the fixing pin 202 to retract, which facilitates the quick and easy disassembly of parts. This greatly improves the flexibility of mold use and the convenience of maintenance. Furthermore, when the fixing pin 202 is retracted into the cavity 208, personnel can directly place the lower mold 3, which has a certain weight, on the support base 2 for alignment operations, avoiding the need for operators to repeatedly move the lower mold 3 for alignment and assembly operations.

[0056] Working principle:

[0057] Upper mold 401 guide: The top plate 4 is slidably sleeved on the guide rod 101. During the extrusion molding process, the sliding cooperation between the top plate 4 and the guide rod 101 provides precise guidance for the up and down movement of the upper mold 401, so that the upper mold 401 can move stably downward along the guide rod 101, ensuring precise docking with the lower mold 3 and improving the extrusion molding accuracy.

[0058] Lower mold 3 placement and alignment: A guide block 302 is installed on the bottom surface of the lower mold 3, and the guide block 302 is slidably sleeved in the support base 2. When assembling the mold, the operator can place the lower mold 3 directly in the support base 2 and move it left and right through the sliding connection between the guide block 302 and the support base 2, thereby performing alignment work after placement.

[0059] Screw 203 Operation and Hydraulic Transmission:

[0060] The operator holds the handle 204 and rotates the screw 203, and the second piston 209, which is fitted on the screw 203, will move accordingly within the connecting pipe 201.

[0061] Since the cavity 208 and the connecting pipe 201 are filled with hydraulic oil, the movement of the second piston 209 will cause pressure changes in the hydraulic oil in the connecting pipe 201.

[0062] Hydraulic oil, as the force transmission medium, evenly transmits the pressure generated by the second piston 209 to the first piston 207.

[0063] Fixed pin 202 telescopically secures the mold:

[0064] The first piston 207 is slidably sleeved in the cavity 208, and the bottom end face of the fixing pin 202 is fitted onto the first piston 207, and the fixing pin 202 is slidably sleeved in the assembly groove 301.

[0065] When the hydraulic oil pressure pushes the first piston 207, the first piston 207 will drive the fixing pin 202 to slide up and down in the assembly groove 301.

[0066] When assembling the lower mold 3, the fixing pin 202 extends to fix and limit the lower mold 3, preventing it from shifting during the extrusion process; when it is necessary to remove or replace the parts, the hydraulic oil pressure is changed by rotating the screw 203 in the opposite direction, causing the fixing pin 202 to retract, so as to facilitate and quickly disassemble the parts.

[0067] Screw 203 anti-loosening: The spring washer 205 sleeved on the screw 203 can maintain the preload on the screw 203 during the operation of the mold and vibration, preventing the screw 203 from loosening due to vibration, ensuring the stability and reliability of the entire hydraulic adjustment system, and enabling the fixing pin 202 to remain in the set position.
