Description

Technical Field

[0001] This invention relates to the technical field of automotive parts, specifically a production line for a foaming mold frame for automotive parts. Background Technology

[0002] Microfoaming refers to the use of thermoplastic materials as a matrix, with the middle layer of the product densely packed with closed micropores ranging in size from ten to tens of micrometers. Compared with conventional injection molding, it has unique advantages in the production of high-precision and expensive automotive parts, and has become an important direction in the development of injection molding technology in recent years.

[0003] In automotive parts manufacturing, the movement of foam mold holders on the foaming line is typically achieved by resting them on the line; the mold holders themselves do not have a power system. The movement and position control of the mold holders are usually achieved by controlling the opening and closing of motors that drive the rollers on the foaming line. However, for specific workstations, such as those requiring material injection into open door foam mold holders, where precise robotic arms are needed for automated operation, the door foam mold holders must maintain a precise position on the foaming line. Due to the inertia of the door foam mold holders moving on the foaming line, controlling their position by opening and closing the motors driving the rollers cannot achieve the required precision for these specific workstations. Furthermore, for actions such as mold opening and closing, the market commonly uses cylinders to drive the mold opening, which can lead to damage to the mold components at the corners where the upper and lower mold holders connect.

[0004] Therefore, it is necessary to provide a production line for foam mold frames of automotive parts, which can achieve the function of automatic control of foam mold frames. Summary of the Invention

[0015] In one embodiment, both transmission rod one and transmission rod two are made of magnetic metal, and both ends of the two transmission rods are rotatably connected to rubber wheels. An electromagnet ring is provided at the connection between the rubber wheel and the transmission rod.

[0016] In one embodiment, the sinking assembly includes an elastic part and a guide part. The guide part includes two concave strips disposed on the upper side of the transmission wheel. One end of the concave strip is fixedly connected to a side plate. A plurality of guide wheels are rotatably connected to the inner side of the concave strip. Wheel grooves are correspondingly opened on both sides of the lower mold frame. The guide wheels roll in the wheel grooves. An inclined plate is fixedly connected to the other end of the concave strip. A plurality of rolling wheels are rotatably connected to the inner side of the inclined plate. The diameter of the rolling wheels is larger than the diameter of the guide wheels. A chamfer is provided at one end of the wheel groove.

A support frame is fixedly connected to one end of the horizontal plate. The horizontal wheels and rolling wheels are all arranged corresponding to the wheel grooves. The elastic part is disposed on the lower side of the guide part and the elastic part and the guide part are staggered.

[0017] In one embodiment, the elastic part includes an L-shaped base, the short side of which is connected to one end of a base plate. The L-shaped base is connected to a support frame.

The hinge round rod slides with the two pairs of slide grooves.

[0019] In one embodiment, the mold opening assembly includes a straight groove and an arc groove. The straight groove is positioned opposite to the guide wheel and is fixedly connected to the double side plates. Both ends of the straight groove extend outward beyond the inclined plate. The straight groove is connected to the arc groove, and the arc groove is connected to the support frame.

[0020] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention uses a stop component to block the moving mold frame assembly. When the mold frame assembly moves to the corresponding station on the foaming line, it moves while rubbing against the first rubber wheel, causing the first rubber wheel to rotate. The first rubber wheel drives the gear component to rotate, thereby driving the gear mechanism to move. The gear mechanism drives the wedge block mechanism to slide against each other, causing the wedge block mechanism to move upward and block the forward path of the mold frame assembly. Then, the ratchet mechanism controls the second rubber wheel to rotate in one direction and not in reverse, so that the blocked mold frame assembly cannot move backward. Thus, in conjunction with the stop component, the positioning restriction of the mold frame assembly is achieved. It has a high degree of automation, does not require an additional drive power mechanism, saves costs, and can position and restrict mold frames of various sizes, making it highly versatile.

[0021] By setting up an opening mold assembly and a sinking assembly, when the lower mold frame in the mold frame assembly enters the sinking assembly along the foaming line, the lower mold frame moves and slowly descends along the sinking assembly, while the upper mold frame moves along the opening mold assembly and is restricted on the opening mold assembly, so that the upper mold frame and the lower mold frame separate in the vertical direction. Then, while the upper mold frame moves along the opening mold assembly, it tilts to open the upper mold frame, realizing the automatic mold opening function without the need for additional power components to drive it, and ensuring that the internal mold parts are not damaged when the upper mold frame hinge flips.

To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0041] Please see Figure 1-8 The present invention provides a technical solution: a production line for foaming mold frames of automotive parts, comprising a foaming line 3, a stop assembly 1, a one-way assembly 6, a mold frame assembly 4, a mold opening assembly 5, and a sinking assembly 2; wherein,

[0042] The mold frame assembly 4 includes an upper mold frame 401 and a lower mold frame 402. The upper mold frame 401 and the lower mold frame 402 are hinged to one end. The mold frame assembly 4 is located on the upper side of the foaming line 3, and the foaming line 3 is used to transport the mold frame assembly 4.

[0043] The stop assembly 1 is located on the lower side of the foaming line 3. The stop assembly 1 includes a rubber wheel 101, a gear and rack meshing mechanism, and a wedge mechanism. The rubber wheel 101 is in contact with the lower end of the mold frame assembly 4. The rubber wheel 101 rolls as the mold frame assembly 4 moves. The rubber wheel 101 drives the gear to rotate and pushes the gear to move. The gear pushes the wedge mechanism to slide against each other. The wedge mechanism slides upward and restricts the forward movement of the mold frame assembly 4.

[0044] One-way component 6 is arranged adjacent to stop component 1. One-way component 6 includes ratchet mechanism and rubber wheel 601. Rubber wheel 601 is in contact with the lower end of mold frame component 4. The ratchet mechanism is connected to rubber wheel 601. The ratchet mechanism restricts the one-way rotation of rubber wheel 601. Rubber wheel 601 is used to restrict the reverse movement of mold frame component 4.

[0045] The sinking component 2 is connected to the foaming line 3. The foaming line 3 transmits the mold frame component 4 into the sinking component 2. The sinking component 2 is used to restrict the movement direction of the lower mold frame 402. The lower mold frame 402 moves along the sinking component 2 and separates from the upper mold frame 401.

[0046] The mold opening component 5 is positioned above the sinking component 2. The mold opening component 5 is used to restrict the movement direction of the upper mold frame 401. The upper mold frame 401 moves along the mold opening component 5 and rotates along the hinge to open the mold.

[0047] Specifically, the mold frame assembly 4 is transported via the foaming line 3. The stop assembly 1 is located at the lower end of the foaming line 3. When the mold frame assembly 4 is transported to the designated processing station, it first passes through rubber wheel 2 601 and then rubber wheel 101. As the lower end of the mold frame assembly 4 moves, it rubs against rubber wheel 101 and rubber wheel 2 601, causing rubber wheel 101 to rotate. Rubber wheel 101 drives the gear component to rotate, thereby driving the gear condition to move. The gear condition causes the wedge block mechanism to slide against each other, causing the wedge block mechanism to move upward and block the forward path of the mold frame assembly 4. Then, through the unidirectional component 6 on the adjacent side, the ratchet mechanism controls rubber wheel 2 601 to rotate only in one direction and not in reverse, so that the blocked mold frame assembly 4 cannot move backward. Thus, in conjunction with the stop assembly 1, the positioning restriction of the mold frame assembly 4 is achieved. The degree of automation is high, no additional drive power mechanism is required, saving costs. Moreover, it can perform positioning restriction on mold frames of various sizes, making it highly versatile.

[0048] When the mold opening action is required, the foaming line 3 drives the mold frame assembly 4 into the sinking assembly 2 and the mold opening assembly 5. When the lower mold frame 402 in the mold frame assembly 4 enters the sinking assembly 2 along the foaming line 3, the lower mold frame 402 moves and slowly descends along the sinking assembly 2, while the upper mold frame 401 moves along the mold opening assembly 5 and is restricted on the mold opening assembly 5, so that the upper mold frame 401 and the lower mold frame 402 separate in the vertical direction. Then, the upper mold frame 401 moves along the mold opening assembly 5 and tilts, thereby opening the upper mold frame 401 and realizing the automatic mold opening function. No extra power components are needed for driving, and it is ensured that the internal mold parts will not be damaged when the upper mold frame 401 hinges flip, thus ensuring the quality of the finished product. When the mold needs to be closed, simply return the upper mold frame 401 and the lower mold frame 402 to the original path to realize automatic mold closing, which has a high degree of automation.

[0049] The foaming line 3 includes a base plate 301, a side plate 302 fixedly connected to one end of the base plate 301, and an upper cover frame 303 fixedly connected to the upper side of the base plate 301. Several sets of transmission wheels 304 are rotatably connected to both ends of the upper cover frame 303. Several square openings are correspondingly provided on the upper side of the upper cover frame 303, and the transmission wheels 304 extend to the upper side of the square openings. The upper ends of the transmission wheels 304 contact the lower mold frame 402. Two rubber wheels 101 are arranged similarly to the transmission wheels 304. A transmission rod 102 is arranged between the two rubber wheels 101, passing through both rubber wheels 101. The gear component includes two gears 103, and both ends of the transmission rod 102 are fixedly connected to the two gears 103. The transmission wheel 304 is driven to rotate by a motor assembly. The gear mechanism includes two racks 104. The lower side of the gear 103 meshes with the racks 104. The lower side of the racks 104 slides with the base plate 301. The two racks 104 are connected by a connecting rod 105. A square through hole is provided on the vertical side wall of the upper cover frame 303. The connecting rod 105 slides in the square through hole. The wedge mechanism includes a triangular wedge 106 and a trapezoidal wedge 107. One side of the connecting rod 105 is fixedly connected to the triangular wedge 106. The lower end of the triangular wedge 106 slides with the base plate 301. The inclined surface of the triangular wedge 106 slides with the inclined surface of the trapezoidal wedge 107. The upper end of the trapezoidal wedge 107 passes through the upper cover frame 303 and slides with it.

[0050] Specifically, the mold frame assembly 4 is moved by several transmission wheels 304. When the mold frame assembly 4 passes the rubber wheel 101, the two rubber wheels 101 are driven to rotate under the action of friction. The rubber wheel 101 drives the transmission rod 102 and the gears 103 at both ends to rotate. The gears 103 mesh with the rack 104, thereby pushing the racks 104 on both sides to move. The racks 104 drive the connecting rod 105 and the triangular wedge 106 to move. The inclined surface of the triangular wedge 106 pushes the inclined surface of the trapezoidal wedge 107, so that the trapezoidal wedge 107 moves along the inclined surface. The trapezoidal wedge 107 passes through the upper cover frame 303 for guidance, so that the trapezoidal wedge 107 moves upward and extends to the upper end of the upper cover frame 303, thereby blocking the mold frame assembly 4 and restricting its forward movement. This realizes the function of automatically positioning the mold frame assembly 4 without the need for an additional power device, thus saving costs.

[0051] The lower end of the upper cover frame 303 is provided with a telescopic rod 108, and the lower end of the telescopic rod 108 is provided with a guide plate 111. The guide plate 111 is fixedly connected to one end of the trapezoidal wedge block 107. The outer side of the telescopic rod 108 is provided with a spring 1, and the two ends of the spring 1 are respectively connected to the upper cover frame 303 and the guide plate 111. One end of the triangular wedge block 106 is provided with a telescopic rod 2 110, and one end of the telescopic rod 2 110 is provided with a fixing plate 109. The fixing plate 109 is fixed to the upper end of the bottom plate 301. The outer side of the telescopic rod 2 110 is provided with a spring 2, and the two ends of the spring 2 are respectively connected to the fixing plate 109 and the triangular wedge block 106.

[0052] Specifically, when the trapezoidal wedge 107 moves, a telescopic rod 108 and a guide plate 111 are provided for further guidance to ensure the stability of the movement. A spring is also provided to facilitate the reset of the trapezoidal wedge 107. Similarly, a telescopic rod 110, a fixing plate 109 and a spring are provided on one side of the triangular wedge 106 to further assist the triangular wedge 106 in resetting.

[0053] Rubber wheel 2 601 is arranged adjacent to rubber wheel 101. Similarly, there are two rubber wheels 2 601 and rubber wheel 101. A transmission rod 2 602 is arranged between the two rubber wheels 2 601. One end of the transmission rod 2 602 passes through the rubber wheel 2 601. The ratchet mechanism includes a ratchet 603 and a pawl 604. One end of the transmission rod 2 602 is fixedly connected to the ratchet 603, and the pawl 604 is rotatably connected to the vertical side wall of the upper cover frame 303.

[0054] Specifically, rubber wheel 2 601 is arranged adjacent to rubber wheel 101, and the mold frame assembly 4 passes through rubber wheel 2 601 first and then rubber wheel 101. Thus, when the mold frame assembly 4 is restricted by the stop assembly 1, rubber wheel 2 601 is located on the lower side of the mold frame assembly 4 and in contact with it. The transmission rod 2 602 and rubber wheel 2 601 are restricted by ratchet 603 and pawl 604, and can only move in one direction, that is, they cannot move backward. In conjunction with the stop assembly 1, the mold frame assembly 4 is restricted to remain stationary, which facilitates the next processing step. In addition, the preferred scheme is to set at least two sets of one-way components 6 to increase the engagement accuracy of the ratchet mechanism, and can restrict mold frames of various sizes, which is highly versatile.

[0055] Both transmission rod 102 and transmission rod 602 are made of magnetic metal. Both ends of the two transmission rods are rotatably connected to rubber wheels. An electromagnet ring 7 is provided at the connection between the rubber wheel and the transmission rod.

[0056] Specifically, when it is necessary to remove the restrictions of the gear assembly 1 and the one-way assembly 6, it is only necessary to de-energize the electromagnet ring 7. At this time, the rubber wheel and the electromagnet ring 7 are connected to each other, and the rubber wheel and the transmission rod are rotatably connected. When the electromagnet ring 7 is de-energized, the rubber wheel and the transmission rod are no longer a whole. That is, when the rubber wheel rotates, the transmission rod does not rotate with it, so that the mold frame assembly 4 can move freely on the rubber wheel without being restricted. After the mold frame assembly 4 passes, the electromagnet ring 7 can be energized again, so that the electromagnet ring 7 and the transmission rod can attract each other and be fixed together, thereby connecting the rubber wheel and the transmission rod together, so that the positioning restriction can be performed again. The operation is simple and convenient, and no power component is required for driving.

[0057] The sinking component 2 includes an elastic part and a guide part. The guide part includes two concave strips 201, which are disposed on the upper side of the transmission wheel 304. One end of the concave strip 201 is fixedly connected to the side plate 302. Several guide wheels 202 are rotatably connected to the inner side of the concave strip 201. Wheel grooves are correspondingly opened on both sides of the lower mold frame 402, and the guide wheels 202 roll in the wheel grooves. The other end of the concave strip 201 is fixedly connected to an inclined plate 203, and the inner side of the inclined plate 203 rotates. Several rolling wheels 204 are connected, the diameter of the rolling wheels 204 is larger than the diameter of the guide wheel 202, one end of the wheel groove is provided with a chamfer, one end of the inclined plate 203 is fixedly connected to a horizontal plate 205, several sets of horizontal wheels 206 are rotatably connected to the inner side of the horizontal plate 205, one end of the horizontal plate 205 is fixedly connected to a support frame 8, the horizontal wheels 206 and the rolling wheels 204 are all arranged corresponding to the wheel groove, the elastic part is arranged on the lower side of the guide part and the elastic part and the guide part are staggered.

[0058] Specifically, when the mold frame assembly 4 moves on the foaming line 3, the wheel groove on the lower mold frame 402 and the guide wheel 202 roll against each other, so that the concave strip 201 and the guide wheel 202 guide the movement of the lower mold frame 402. With the guidance, the lower mold frame 402 moves along the concave strip 201 and finally contacts the rolling wheel 204 in the inclined plate 203. At the same time that the chamfer in the wheel groove contacts the rolling wheel 204, the lower mold frame 402 moves downward with the inclined rolling wheel 204, thereby separating from the upper mold frame 401.

[0059] The elastic part includes an L-shaped base 207, the short side of which is connected to one end of the base plate 301. The L-shaped base 207 is connected to the support frame 8. Double side plates 208 are fixedly connected to both ends of the L-shaped base 207. The inner sidewalls of the double side plates 208 are fixedly connected to the inclined plate 203. Several sets of telescopic columns 209 are provided at the upper end of the L-shaped base 207. A lifting plate 210 is provided at the upper end of the telescopic columns 209. Several sets of drive wheels 211 are provided at the upper end of the lifting plate 210. The drive wheels 211 are driven to rotate by a motor assembly. The diameter of the drive wheels 211 is equal to the diameter of the transmission wheel 304 and the two are on the same horizontal line. Springs 212 are provided on the outer side of the telescopic columns 209. The two ends of the springs 212 are connected to the lifting plate 210 and the L-shaped base 207, respectively.

[0060] Specifically, before the lower mold frame 402 separates from the upper mold frame 401, that is, before the mold frame assembly 4 contacts the rolling wheel 204, the mold frame assembly 4 will first move from the foaming line 3 to several drive wheels 211 for transmission. The lower side of the drive wheel 211 is provided with a lifting plate 210, a telescopic column 209 and a spring 212 to provide elastic support for the drive wheel 211. When the lower mold frame 402 tilts and moves down with the rolling wheel 204, the spring 212 and the telescopic column 209 are compressed, the lifting plate 210 and the drive wheel 211 descend. Under the elastic force of the spring 212, the drive wheel 211 and the lower mold frame 402 always remain in close contact, which facilitates the transmission of the mold frame assembly 4 by the drive wheel 211.

[0061] Several sets of guide wheels 403 are provided on the lower ends of both sides of the upper mold frame 401. Two pairs of hinge square rods 404 are fixedly connected to one end of the lower mold frame 402. An open slide groove 406 is provided on the upper side of the hinge square rod 404 near the mold opening component 5, and a closed slide groove 407 is provided on the upper side of the hinge square rod 404 away from the mold opening component 5. Four square holes 405 are provided on both sides of the upper mold frame 401 respectively. The square holes 405 slide with the hinge square rods 404. A hinge round rod 408 is provided inside the square hole 405. The hinge round rods 408 slide with the two pairs of slide grooves.

[0062] Specifically, since the hinge square rods 404 at both ends of the lower mold frame 402 are inserted into the square holes 405 on the upper mold frame 401 and the two are slidably engaged, while the hinge round rod 408 slides in the groove, it guides the separation of the upper mold frame 401 and the lower mold frame 402 when they separate, so that when the lower mold frame 402 separates downward, it can move vertically downward relative to the upper mold frame 401, thereby ensuring that the internal mold parts are not damaged.

[0063] The mold opening assembly 5 includes a straight groove 501 and an arc groove 502. The straight groove 501 is positioned opposite to the guide wheel 403. The straight groove 501 is fixedly connected to the double side plates 208. Both ends of the straight groove 501 extend outward beyond the inclined plate 203. The straight groove 501 is connected to the arc groove 502, and the arc groove 502 is connected to the support frame 8.

[0064] Specifically, since both ends of the straight groove 501 extend outward beyond the inclined plate 203, before the lower mold frame 402 contacts the rolling wheel 204 and descends to separate from the upper mold frame 401, the guide wheel 403 on the lower side of the upper mold frame 401 has already entered the straight groove 501. The guide wheel 403 moves along the straight groove 501, so that the straight groove 501 guides the upper mold frame 401 and restricts its movement direction. Then, as the lower mold frame 402 contacts the rolling wheel 204, separation is achieved. Until the lower mold frame 402 completes separation and enters several horizontal wheels 206, the lower mold frame 402 is in a stable state. At this time, the upper mold frame 401 on the upper side is also driven by the lower mold frame 402 and moves along the arc groove 502. Since the upper side of the hinge square rod 404 near one end of the mold opening component 5 is opened... An open slide 406 is provided, and a closed slide 407 is provided inside the upper side of the hinge square rod 404 at the end away from the mold assembly 5. Therefore, the end of the upper mold frame 401 that first enters the arc groove 502 moves along the arc and thus tilts and rotates. At the same time as it tilts and rotates, the hinge round rod 408 at the other end is restricted in the closed slide 407. Therefore, as the open slide 406 releases the hinge round rod 408 and tilts and rotates upward, the hinge round rod 408 in the closed slide 407 is restricted and rotates accordingly, thereby completing the automatic opening of the upper mold frame 401 and realizing the automatic mold opening function. No additional drive device is required. When the mold needs to be closed, it is only necessary to control the drive wheel 211 to reverse and drive the upper mold frame 401 and the lower mold frame 402 to move in opposite directions to return to the original state when the mold is closed, which is quite convenient.
