Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically to an automotive instrument bracket die. Background Technology

[0002] Molds are generally used in industrial production to create various molds and tools for obtaining desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. The car instrument bracket is one of the important parts of a car, and mold stamping is used when processing the car instrument bracket.

[0003] A search revealed an existing patent (publication number: CN212469477U) that discloses an automotive instrument bracket mold. During use, the required raw materials for the bracket are fed into the upper mold mechanism through a feeding hole, and the upper mold base is easily lifted using a handle. The punch performs stamping on the automotive instrument bracket, and the positioning groove positions the upper and lower mold mechanisms to ensure accurate insertion of the upper mold into the lower mold mechanism, thus improving the quality of bracket production. However, the inventors discovered the following problems with the existing technology during the development of this utility model: When stamping the workpiece, the aforementioned automotive instrument bracket mold requires mold closing, followed by manual lifting of the upper mold using a handle. Only after lifting the upper mold can the stamped part be easily removed from the mold. After stamping, because the workpiece is pressed against both the upper and lower molds, manual lifting of the upper male mold due to friction makes demolding difficult, reducing the efficiency and convenience of mold use for the operator.

[0004] In view of this, the present invention proposes an easy-to-use automotive instrument bracket mold to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automotive instrument bracket mold to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: an automotive instrument bracket mold, including a base, a female mold fixedly installed on the upper surface of the base, a top plate provided on the upper side of the female mold, a male mold fixedly installed at the bottom of the top plate, the male mold and the female mold being compatible, and an opening mold assembly and a closing mold assembly respectively provided between the base and the top plate.

[0007] The mold opening assembly includes a vertical slide rod fixedly installed on the upper surface of the base. A top frame is fixedly installed at the top of the vertical slide rod. The surface of the top frame is reserved with a clearance opening for an external hydraulic rod to extend into. The top plate is slidably connected to the surface of the vertical slide rod, and a support spring for driving the top plate to move upward is sleeved on the surface of the vertical slide rod.

[0008] The mold closing assembly includes mounting slots symmetrically opened on the left and right sides of the bottom end of the top plate. A transverse slide rod is fixedly installed inside the mounting slot. A locking pin is slidably connected to the surface of the transverse slide rod. A locking groove is opened on the side of the female mold. When the male mold and the female mold are closed, the locking pin is locked inside the locking groove.

[0009] Furthermore, a return spring is sleeved on the surface of the transverse slide bar to drive the locking pin to move towards the center of the female mold; by setting the return spring, the elasticity of the return spring can drive the locking pin to lock into the slot.

[0010] Furthermore, the bottom end of the locking pin is provided with an inclined surface. When the locking pin contacts the female mold during its downward movement, the locking pin slides with the upper edge of the female mold through the inclined surface. By providing the inclined surface, when the male mold moves downward, the locking pin slides with the female mold through the inclined surface to avoid the female mold.

[0011] Furthermore, a handle is fixedly installed on the side wall of the latch, and a lever is fixedly installed on the side wall of the top plate, with the handle and lever being positioned to match each other. By setting the handle and lever, when the operator opens the latch, the palm is pressed against the lever, and the fingers are bent to pull the lever, making it convenient to apply force to quickly open the latch.

[0012] Furthermore, the base is provided with a first auxiliary demolding component and a second auxiliary demolding component respectively corresponding to the female mold.

[0013] Furthermore, the first auxiliary demolding assembly includes a drive motor fixedly installed on the left side of the base. A crankshaft is fixedly installed on the output shaft surface of the drive motor, and a transmission rod is rotatably connected to the surface of the crankshaft. A vibration chamber is opened at the bottom end of the base. A limit slide rod is fixedly installed on the inner wall of the vibration chamber. A reciprocating plate is slidably connected to the surface of the limit slide rod. Rubber hammers are provided on both the left and right sides of the reciprocating plate. The end of the transmission rod away from the crankshaft extends into the interior of the vibration chamber and is rotatably connected to the reciprocating plate. The drive motor drives the crankshaft to rotate. Under the transmission action of the transmission rod, the reciprocating plate slides left and right on the surface of the limit slide rod, causing the rubber hammers to impact the vibration chamber and vibrate the mold, so that the stamped part is loosened from the inner wall of the mold, making it easier to remove the stamped part from the mold.

[0014] Furthermore, the second auxiliary demolding component includes a sealing sleeve embedded in the inner top wall of the base. An air pipe is embedded in the side wall of the sealing sleeve, and the air inlet end of the air pipe extends to the right side of the base and is connected to an external high-pressure air tank. A stepped hole extending into the sealing sleeve is opened at the bottom end of the female mold. A circular plate is slidably connected inside the stepped hole, and the circular plate is adapted to the inner diameter of the stepped hole. A circular rod is fixedly installed at the bottom end of the circular plate, and the bottom end of the circular rod extends into the interior of the sealing sleeve. A clamping spring is sleeved on the surface of the circular rod to drive the circular plate to close with the stepped hole. After the mold is opened, the external high-pressure gas is input into the interior of the sealing sleeve through the air pipe. The air pressure overcomes the elasticity of the clamping spring and pushes the circular rod and circular plate upward, thereby lifting the stamped part upward and further reducing the demolding difficulty of the stamped part.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. This utility model involves placing the stamping material of an automotive instrument bracket into the female mold, and using an external hydraulic device to press the top plate downwards, thereby driving the male mold and female mold to close and achieve the purpose of stamping the instrument bracket. During mold closing, a locking pin is inserted into a slot to maintain the mold closing state and ensure the stamping and shaping effect. By opening the locking pin, the top plate and male mold can be moved upwards under the elastic force of the support spring, achieving a rapid mold opening effect and improving the efficiency and convenience of mold use.

[0017] 2. This utility model, by setting a return spring, utilizes the elasticity of the return spring to drive the locking pin to lock with the locking groove. By setting an inclined surface, when the male mold moves down, the inclined surface slides with the female mold, which facilitates the sliding of the locking pin to avoid the female mold. By setting a handle and a pull handle, when the operator opens the locking pin, the palm is pressed against the handle and the fingers are bent to pull the pull handle, which facilitates the quick opening of the locking pin.

[0018] 3. This utility model, by setting a first auxiliary demolding component, drives the crankshaft to rotate via a drive motor. Under the transmission action of the transmission rod, the reciprocating plate slides left and right on the surface of the limiting slide rod, causing the rubber hammer to impact the vibration chamber and vibrate the die, loosening the stamped part from the inner wall of the die, making it easier to remove the stamped part. By setting a second auxiliary demolding component, after the die is opened, external high-pressure gas is introduced into the sealed sleeve through the air pipe. The air pressure overcomes the elasticity of the retaining spring and pushes the round rod and round plate upward, thereby lifting the stamped part upward, further reducing the demolding difficulty of the stamped part. In addition, the high-speed flow of gas inside the die can assist in cleaning the inside of the die by blowing away debris, ensuring the quality of stamping processing using the die.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automobile instrument bracket mold involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figure 1-6 This utility model provides an automotive instrument bracket mold, including a base 1, a female mold 2 fixedly installed on the upper surface of the base 1, a top plate 3 provided on the upper side of the female mold 2, and a male mold 4 fixedly installed at the bottom end of the top plate 3, the male mold 4 being compatible with the female mold 2.

[0028] In use, the stamping material of the car instrument bracket is placed inside the female mold 2, and the top plate 3 is pressed down by an external hydraulic device, which drives the male mold 4 to close with the female mold 2, thereby achieving the purpose of stamping the instrument bracket.

[0029] A mold opening component and a mold closing component are respectively provided between the base 1 and the top plate 3.

[0030] The mold opening assembly includes a vertical slide bar 5 fixedly installed on the upper surface of the base 1. A top frame 6 is fixedly installed at the top of the vertical slide bar 5. The surface of the top frame 6 is reserved with a clearance opening for the external hydraulic rod to extend into. The top plate 3 is slidably connected to the surface of the vertical slide bar 5, and a support spring 7 for driving the top plate 3 to move upward is sleeved on the surface of the vertical slide bar 5.

[0031] The mold closing assembly includes mounting slots symmetrically opened on the left and right sides of the bottom end of the top plate 3. A transverse slide rod 8 is fixedly installed inside the mounting slot. A locking pin 9 is slidably connected to the surface of the transverse slide rod 8. A locking groove 10 is opened on the side of the female mold 2. When the male mold 4 and the female mold 2 are closed, the locking pin 9 is locked inside the locking groove 10.

[0032] When the mold is closed, the locking pin 9 is inserted into the locking groove 10 to maintain the closed state and ensure the stamping and shaping effect of the mold. When the locking pin 9 is opened, the top plate 3 and the male mold 4 can be moved upward under the elastic force of the support spring 7, so as to achieve the effect of quick mold opening and improve the efficiency and convenience of mold use.

[0033] A return spring 11 is fitted on the surface of the transverse slide bar 8 to drive the locking pin 9 to move toward the center of the female mold 2.

[0034] By setting a reset spring 11, the elasticity of the reset spring 11 can drive the locking pin 9 to lock into the locking slot 10.

[0035] The bottom end of the locking pin 9 is provided with an inclined surface 12. When the locking pin 9 moves down and comes into contact with the female mold 2, the locking pin 9 slides and connects with the upper edge of the female mold 2 through the inclined surface 12.

[0036] By setting the inclined surface 12, when the male mold 4 moves down, the inclined surface 12 slides with the female mold 2, which facilitates the sliding of the locking pin 9 to avoid the female mold 2.

[0037] A handle 13 is fixedly installed on the side wall of the latch 9, and a handle 14 is fixedly installed on the side wall of the top plate 3. The positions of the handle 13 and the handle 14 are matched.

[0038] By setting handle 14 and lever 13, when the operator opens the latch 9, the palm is pressed against handle 14 and the fingers are bent to pull lever 13, which makes it easy to apply force to quickly open the latch 9.

[0039] The base 1 is provided with a first auxiliary demolding component and a second auxiliary demolding component respectively corresponding to the female mold 2.

[0040] The first auxiliary demolding component in this embodiment includes a drive motor 15 fixedly installed on the left side of the base 1. A crankshaft 16 is fixedly installed on the output shaft surface of the drive motor 15. A transmission rod 17 is rotatably connected to the surface of the crankshaft 16. A vibration cavity 18 is opened at the bottom end of the base 1. A limiting slide rod 19 is fixedly installed on the inner wall of the vibration cavity 18. A reciprocating plate 20 is slidably connected to the surface of the limiting slide rod 19. Rubber hammers 21 are provided on both the left and right sides of the reciprocating plate 20. The end of the transmission rod 17 away from the crankshaft 16 extends into the interior of the vibration cavity 18 and is rotatably connected to the reciprocating plate 20.

[0041] When preparing to open the mold, the overall mold is connected to the external power control system in advance. By setting the first auxiliary demolding component, the drive motor 15 drives the crankshaft 16 to rotate. Under the transmission action of the transmission rod 17, the reciprocating plate 20 slides left and right on the surface of the limit slide rod 19, which drives the rubber hammer 21 to impact the vibration chamber 18 and vibrate the mother mold 2, so that the stamped part is loosened from the inner wall of the mother mold 2, making it easier to remove the stamped part from the mold.

[0042] The second auxiliary demolding component in this embodiment includes a sealing sleeve 22 embedded in the inner top wall of the base 1. An air pipe 23 is embedded in the side wall of the sealing sleeve 22. The air inlet end of the air pipe 23 extends to the right side of the base 1 and is connected to an external high-pressure air tank. A stepped hole 24 extending into the sealing sleeve 22 is opened at the bottom end of the female mold 2. A circular plate 25 is slidably connected inside the stepped hole 24, and the inner diameter of the circular plate 25 is adapted to the inner diameter of the stepped hole 24. A circular rod 26 is fixedly installed at the bottom end of the circular plate 25, and the bottom end of the circular rod 26 extends into the interior of the sealing sleeve 22.

[0043] A clamping spring 27 is fitted onto the surface of the round rod 26 to engage the driving round plate 25 with the stepped hole 24.

[0044] By setting a second auxiliary demolding component, after the mold is opened, external high-pressure gas is introduced into the sealing sleeve 22 through the air pipe 23. The air pressure overcomes the elastic force of the clamping spring 27 to push the round rod 26 and the round plate 25 upward, thereby lifting the stamped part upward and further reducing the demolding difficulty of the stamped part. In addition, the high-speed flow of gas inside the mother mold 2 can assist in cleaning the inside of the mother mold 2 by blowing away debris, ensuring the quality of stamping processing using the mother mold 2.

[0045] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model.
