Description

Technical Field

[0002] With the development of intelligent automobiles, the functional integration of the central control interface panel cover in the central control area is becoming higher and higher. Generally, the central control interface panel cover is equipped with a USB connector, a Type-C connector and an operating indicator light for displaying its working status.

[0003] In the related art, the injection mold used for injection molding the central control interface panel cover needs to set the upper mold core, lower mold core and side position according to the shape of the central control interface panel cover for injection molding, and configure the first insert according to the USB connector and Type-C connector to injection mold the plug interface, and configure the second insert according to the position of the working indicator light to injection mold the mounting port; and these side positions, first inserts and second inserts need to be respectively equipped with independent hydraulic cylinders to drive them to move and complete core pulling. This belongs to the multi-cylinder sequential core pulling technology. However, the defect of this injection mold is that hydraulic cylinders need to be arranged around the injection mold to drive the corresponding side positions, first inserts and second inserts to move, and each hydraulic cylinder also needs to be equipped with matching oil pumps, filters, pipes and seals; its structure is relatively complex, which makes the debugging cycle of the injection mold longer and inconvenient for subsequent repair and maintenance, and at the same time causes the manufacturing cost of the injection mold to increase by 15%-20%.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide an injection mold for a central control socket panel cover of an automobile, which effectively solves the technical defects in the prior art of the injection mold used for injection molding the central control socket panel cover, such as the complex structure and high manufacturing cost.

[0007] The advantageous effect of the injection mold for the automobile central control socket panel cover provided by the present application is that, when the mold is opened after the automobile central control socket panel cover is injection molded, the panel is first driven to move upward by a first distance, which can cause the transfer slider to move leftward to retract the first protrusion and the right slider to move obliquely upward, so that the transfer slider is separated from the indicator light installation port and the right slider, and the second protrusion is separated from the automobile central control socket panel cover; and then, the panel is driven to move upward by a second distance, which can cause the left slider to move obliquely upward, the upper mold base to move upward, and the right slider to move obliquely upward, so that the automobile central control socket panel cover is completely separated from the left slider, the right slider, and the upper mold core; Compared with the existing technology, firstly, by controlling the drive panel to move the first distance and the second distance, the transfer slide, the right slide, the left slide and the upper mold base can be moved in a hierarchical linkage manner, so that the core pulling and demoulding operations can be completed in one mold opening; there is no need to configure hydraulic cylinders and oil circuit control systems according to the transfer slide, the right slide and the left slide, which can reduce the manufacturing cost of the injection mold by 15%-20%; at the same time, it can simplify the overall structure of the injection mold, thereby shortening the time required for injection mold debugging and facilitating subsequent repair and maintenance; Secondly, the sequential mold opening operation is performed by mechanically moving the transfer slide, right slide, left slide, and upper mold base only through the mechanical movement of the drive panel.

Among them, the upper mold base 20 is provided with a left slide 23 and a right slide 24 that can be moved obliquely; the right side of the left slide 23 is provided with a first convex portion 231 for injection molding the front cavity 2001, and the surface of the first convex portion 231 is provided with a molding convex point 2311 for injection molding the plug interface 2004, and the left side of the right slide 24 is provided with a second convex portion 241 for injection molding the back cavity 2002; the left slide 23 is provided with a movable adapter slide 25, and the adapter slide 25 can extend from the right side of the first convex portion 231 to the injection molding indicator light installation port 2003; when the driving panel 22 moves up a first distance x1, it can drive the adapter slide 25 to retract the first convex portion 231 to the left and drive the right slide 24 to move obliquely upward; when the driving panel 22 moves up a second distance x2, it can drive the left slide 23 to move obliquely upward, the upper mold base 20 to move up and the right slide 24 to move obliquely upward.

[0028] It can be understood that the molding chamber used for injection molding the automotive center console panel cover 200 is enclosed by the lower mold core 11, the upper mold core 21, the left runner 23, and the right runner 24. The first protrusion 231 is used to injection mold the front cavity 2001 and, through the molding protrusion 2311, the plug interface 2004 is injection molded on one surface of the front cavity 2001, while the adapter runner 25 is used to injection mold the indicator light installation port 2003 on the other surface of the front cavity 2001. The second protrusion 241 is used to injection mold the back cavity 2002. The lower mold core 11 is equipped with a lower punch 111, which is capable of injection molding the snap structure and frame 2005 at the bottom of the automotive center console panel cover 200.

[0029] Specifically, when the mold is opened after the automobile central control socket panel cover 200 is injection molded, the driving panel 22 is first moved up by a first distance x1, which can cause the transfer position 25 to move leftward and retract the first protrusion 231 and the right position 24 to move upward obliquely, so that the transfer position 25 is separated from the indicator light installation port 2003 and the right position 24 and the second protrusion 241 are separated from the automobile central control socket panel cover 200; then, the driving panel 22 is moved up by a second distance x2, which can cause the left position 23 to move upward obliquely. , the upper mold base 20 moves up and the right slide 24 moves obliquely upward, so that the car center console socket panel cover 200 is completely separated from the left slide 23, the right slide 24 and the upper mold core 21; compared with the prior art, in the first aspect, by controlling the driving panel 22 to move the first distance x1 and the second distance x2, the hierarchical linkage transfer slide 25, the right slide 24, the left slide 23 and the upper mold base can be realized to complete the core pulling and demoulding operation at one time; there is no need to adjust the slide 25, the right slide 24, the left slide 23 and the upper mold base according to the transfer distance x1 and the second distance x2. The side slide 23 is equipped with a hydraulic cylinder and an oil circuit control system, which can reduce the manufacturing cost of the injection mold by 15%-20%; at the same time, it can simplify the overall structure of the injection mold, thereby shortening the time required for injection mold debugging and facilitating subsequent repair and maintenance; secondly, the transfer slide 25, the right slide 24, the left slide 23 and the upper mold base 20 are linked by mechanical movement of the drive panel 22 to perform sequential mold opening operations, which can completely avoid the problem of asynchrony caused by pressure fluctuations that often occurs in the hydraulic cylinder system, thereby improving the production operation reliability of the injection mold; thirdly, by movably arranging the transfer slide 25 on the left slide 23, and combining the structure of the drive panel 22 to link the transfer slide 25, the right slide 24, the left slide 23 and the upper mold base 20 in a graded manner, there is no need to set a hydraulic cylinder, which can make the overall structure of the injection mold more compact, so that the injection mold can be adapted to a small injection molding machine for injection molding the automobile central control socket panel cover 200.

[0030] In some embodiments, a first oblique guide groove 211 is provided on the left side of the upper mold core 21 for movably installing the left slide 23, and a second oblique guide groove 212 is provided on the right side of the upper mold core 21 for movably installing the right slide 24; a first mounting seat 221 is provided at the bottom of the driving panel 22, the first mounting seat 221 is provided with a left side rod 2211, and the left slide 23 is provided with a first active hole 232 for inserting the left side rod 2211; a second mounting seat 222 is provided at the bottom of the driving panel 22, the second mounting seat 222 is provided with a right side rod 2221, and the right slide 24 is provided with a second active hole 242 for inserting the right side rod 2221.

[0031] Furthermore, the left row 23 is provided with a transfer guide groove 233; one end of the transfer guide groove 233 passes through the surface of the first protrusion 231, and the other end passes through the bottom surface of the left row 23; the transfer row 25 is movably installed in the transfer guide groove 233 and can extend or retract from the surface of the first protrusion 231; a transfer movable seat 251 is movably installed at the bottom of the left row 23; the right end of the transfer movable seat 251 is provided with a T-shaped slot 2511, and the left end of the transfer row 25 is provided with a T-shaped limiting portion 252 which is movably restricted by the T-shaped slot 2511; the right end of the transfer movable seat 251 is provided with a third action hole 2512 for inserting the left rod 2211, and the diameter of the first action hole 232 is larger than the diameter of the third action hole 2512.

[0032] Specifically, a transfer mounting groove 234 is provided at the bottom of the left row 23, and the right end of the transfer mounting groove 234 is conductively connected to the left end of the transfer guide groove 233. The transfer movable seat 251 can be movably installed in the transfer mounting groove 234 so that the bottom surface of the transfer movable seat 251 is flush with the bottom surface of the left row 23; a stroke limiting notch 2513 is provided on the front or rear side of the bottom of the transfer movable seat 251, and a stroke limiting block 235 is fixed to the bottom of the left row 23 by screws, and one end of the stroke limiting block 235 is limited by the stroke limiting notch 2513, and the left-right width of the stroke limiting notch 2513 is smaller than the left-right width of the stroke limiting notch 2513.

[0033] When repairing and maintaining the left row 23, the right row 24 and the transfer row 25, the driving panel 22 is moved upward to disengage the left rod 2211 from the first action hole 232 and the right rod 2221 from the second action hole 242, so that the left row 23 can be taken out from the first oblique guide groove 211 and the right row 24 can be taken out from the second oblique guide groove 212; then, by removing the stroke limiting block 235, the transfer movable seat 251 can be taken out from the transfer mounting groove 234, and the transfer row 25 can be taken out from the transfer guide groove 233; such a structure facilitates the replacement or repair of parts such as the left row 23, the right row 24, the transfer movable seat 251 and the transfer row 25.

[0034] More specifically, the left side rail 23 is detachably mounted with a stroke limiting square column 2331 on the top of the transfer guide groove 233, and the top of the transfer rail 25 is provided with a stroke limiting groove 253 used in conjunction with the stroke limiting square column 2331. The width of the stroke limiting square column 2331 in the left and right directions is smaller than the length of the stroke limiting groove 253 in the left and right directions; when the transfer rail 25 extends from the first protrusion 231, the stroke limiting square column 2331 can abut against the left end of the stroke limiting groove 253; when the transfer rail 25 is retracted from the first protrusion 231, the stroke limiting square column 2331 can abut against the right end of the stroke limiting groove 253. With such a structure, the stroke limiting square column 2331 can be used to control the distance that the adapter position 25 extends from the first protrusion 231. By adjusting the different distances at which the adapter position 25 extends from the first protrusion 231, it can be adapted to the use of automobile central control socket panel covers of different thicknesses; at the same time, different adapter positions 25 can be replaced according to the different sizes of indicator light mounting ports 2003, and indicator light mounting ports 2003 of different sizes can be injection molded in the automobile central control socket panel cover.

The structure of the stroke limiting square post 2331 and the stroke limiting groove 253 can be used to improve the displacement control accuracy of the transfer slide 25, and no position sensor is required for control, which further simplifies the overall structure of the injection mold and reduces the time and manufacturing cost of injection mold debugging. Moreover, the function of the square post 2331 is not limited to limiting the movement stroke of the transfer slide 25. In addition, when the driving panel 22 moves up to the second stroke, the stroke limiting square post 2331 can be used to abut against the left end of the stroke limiting groove 253 and work with the left rod to move the left slide diagonally upward, thereby improving the reliability of the left slide 23 in moving and opening the mold.

When the upper mold base 20 and the lower mold base 10 are closed, the first locking module 223 and the second locking module 224 can provide a force on the left slide 23 and the right slide 24 to ensure that the lower mold core 11, the upper mold core 21, the left slide 23, the right slide 24, and the transfer slide 25 can reliably enclose the cavity for injection molding the automobile center console panel cover.

[0037] Furthermore, the first lock module 223 is provided with a guide lock groove 2232 that passes through its upper surface and the first active inclined surface 2231, and a movable column 2233 that can move up and down is provided in the guide lock groove 2232. An elastic member 2234 is provided at the top of the movable column 2233 and the drive panel 22, and a third abutting inclined surface 2235 that can abut against the first abutting inclined surface 236 is provided at the bottom of the movable column 2233. The left side rod 2211 is set to be tilted to the left from top to bottom, and the right side rod 2221 is set to be tilted to the right from top to bottom; when the driving panel 22 moves up a first distance x1, the left side rod 2211 can act on the transfer moving seat 251 to move diagonally upward to the left and link the transfer row 25 to move diagonally downward to the left, and the right side rod 2221 can act on the right row 24 to move diagonally upward to the right; when the driving panel 22 moves up a second distance x2, the left side rod 2211 can act on the left row 23 to move diagonally upward to the left, and the right side rod 2221 can act on the right row 24 to move diagonally upward to the right.

[0038] Specifically, the direction of vertical movement of the upper mold base 20 relative to the lower mold base 10 is defined as the first axis b1. The left side bar 2211 is tilted from top to bottom and leftward along the second axis b2. The second axis b2 forms a first angle a1 with the first axis b1. The first operating hole 232 has the same tilt direction as the left side bar 2211. The right side bar 2221 is tilted from top to bottom and rightward along the third axis b3. The third axis b3 forms a second angle a2 with the first axis b1. The second operating hole 242 has the same tilt direction as the right side bar 2221. The first operating hole 232 extends through the top and bottom surfaces of the left side slider 23, while the second left and right operating holes extend through the top and bottom surfaces of the right side slider 24. This allows the left side bar 2211 to abut against the wall of the first operating hole 232 when it moves upward, thereby causing the left slider to move diagonally upward to the left. When the right side bar 2221 moves upward, it abuts against the wall of the second operating hole 242, thereby causing the right side slider 24 to move diagonally upward to the right.

[0039] More specifically, the left runner 23 moves diagonally upward to the left or downward to the right along a fourth axis b4, forming a third angle a3 with the first axis b1. The right runner 24 moves diagonally downward to the left or upward to the right along a fifth axis b5, forming a fourth angle a4 with the first axis b1. After the left and right runners 23 and 24 have moved diagonally downward, the lower mold core 11, upper mold core 21, left runner 23, transfer runner 25, and right runner 24 can be assembled to form the automotive center console panel cover. The first angle a1 is 31 degrees, the second angle a2 is 18 degrees, the third angle a3 is 57 degrees, and the fourth angle a4 is 70 degrees.

[0040] Furthermore, the moving direction of the transfer movable seat 251 is the same as the moving direction of the left slide 23. The transfer slide 25 moves obliquely downward to the left or obliquely upward to the right along the sixth axis b6. The sixth axis b6 and the first axis b1 form a fifth angle a5, which is 72 degrees. The first protrusion 231 of the left slide 23 has a first molding surface 2312 at the bottom right and a second molding surface 2313 at the top right. The molding protrusion 2311 is provided on the first molding surface 2312. It can extend or retract from the second molding surface 2313; when the left row position 23 moves obliquely to the right and downward, the front concave cavity of the car's central control socket panel cover can be formed through the first protrusion 231. At this time, the front concave cavity has at least a first surface formed by the first molding surface 2312 and a second surface formed by the second molding surface 2313, and the molding protrusion 2311 is injection-molded into the plug interface 2004 on the first surface, and the adapter row position 25 extends from the second molding surface 2313 and is injection-molded into the indicator light mounting port 2003 on the second surface.

[0041] It should be noted here that there are one or more molding protrusions 2311, and the molding protrusions 2311 are used for injection molding of USB plug interfaces or TYPE-C plug interfaces; according to actual production needs, the left row position 23 with different molding protrusions 2311 can be replaced to adapt to the injection molding of different types of plug interfaces.

[0042] Specifically, the driving panel 22 is equipped with a glue injection port 225, and the upper mold base 20 and the upper mold core 21 are provided with a glue injection channel. When the driving panel 22 moves downward and causes the upper mold base 20 to move downward relative to the lower mold base 10 to complete the mold closing, the glue injection port 225 can be connected to the cavity used for injection molding the automobile central control socket panel cover through the glue injection channel, and the hot melt slurry is injected into the cavity through the glue injection port 225 and the glue injection channel by using an injection molding machine. After the hot melt slurry in the cavity cools, the automobile central control socket panel cover can be injection molded. The driving panel 22 is provided with a guide column, and the lower die base 10 and the upper die base 20 are provided with guide holes for the movably inserted guide columns; the lower die base 10 can be moved up and down and is equipped with an ejector plate 12, and the top of the ejector plate 12 is provided with an ejector pin 121. By driving the ejector plate 12 upward, the ejector pin 121 can be extended from the surface of the lower die core 11 to eject the car center console panel cover attached to the lower die core 11 and the lower punch 111. These are conventional design methods of those skilled in the art and will not be elaborated here.

[0043] More specifically, when the drive panel 22 moves downward, it drives the lower mold base 10 downward, allowing the upper mold core 21, lower mold core 11, left slide 23, right slide 24, and transfer slide 25 to close together and form the cavity for injection molding the automotive center console panel cover. After the center console panel cover is molded, the mold is opened, and the drive panel 22 moves upward in stages to complete the mold opening. When the driving panel 22 moves up for the first time, the driving panel 22 moves up a first distance. Because the diameter of the first action hole 232 of the left slide 23 is larger than the diameter of the third action hole 2512 of the transfer movable seat 251, and the elastic member 2234 provides a downward elastic force for the movable column 2233, the movable column 2233 continues to act on the left slide 23 and does not move; the left side rod 2211 drives the transfer movable seat 251 to move obliquely to the left and upward, and links the transfer slide 25 to move obliquely to the left and downward, so that the transfer slide 25 is demolded from the indicator light mounting port 2003; while the left side rod 2211 acts on the transfer movable seat 251 to move, the right side rod 2221 acts on the right slide 24 to move obliquely to the right and upward, so that the right slide 24 and the car's central control socket panel cover are demolded; at this time, the lower mold core 11 and the lower punch 111 of the left slide 23 have not completed demolding. Then, the panel 22 is driven to continue to move up a second distance x2 on the basis of the first distance, so that the left rod 2211 can drive the left slide 23 and the transfer movable seat 251 to move obliquely to the left and up, allowing the left slide 23 and the car's central control socket panel cover to complete demoulding. At this time, the right rod 2221 only acts on the right slide 24 to move up synchronously but does not participate in demoulding. Finally, by driving the ejector plate 12 to move up, the ejector pin 121 extends upward from the surface of the lower mold core 11 and the lower punch 111, and the car's central control socket panel cover can be ejected from the lower mold core 11 and the lower punch 111.

[0044] In other embodiments, a chain or a connecting rope (not shown in the figure) is provided between the driving panel 22 and the ejector plate 12. When the driving panel 22 moves up to the second distance x2, the chain or the connecting rope is utilized to link the ejector plate 12 to move up. Thus, after the driving panel 22 moves up to the second distance x2, the ejector pin 121 is synchronously linked to eject the cover of the central control socket panel of the automobile.

[0045] It should be noted that the automobile central control socket panel cover injection mold 100 is a double-cavity injection mold.

[0046] The present application also provides an injection molding method for a car central control socket panel cover, which is applied to an injection molding mold 100 for a car central control socket panel cover. The injection molding method for the car central control socket panel cover comprises the following steps: Step 1: Provide an automobile center console panel cover injection mold 100 and install it in an injection molding machine. Connect the drive panel 22 with the hydraulic rod of the injection molding machine and control the drive panel 22 to move up and down to close or open the mold. Step 2: The driving panel 22 is moved downward by controlling the injection molding machine, so that the lower mold core 11, the left slide 23, the transfer slide 25, the right slide 24 and the upper mold core 21 are combined to injection mold the automobile center console panel cover; Step 3: Control the driving panel 22 to move up a first distance. The left rod 2211 moves up and causes the transfer movable seat 251 to move diagonally upward to the left, thereby linking the transfer slider 25 to move diagonally downward to the left, thereby demolding the transfer slider 25 from the indicator light mounting opening 2003. The right rod 2221 moves up and causes the right slider 24 to move diagonally upward to the right, thereby demolding the right slider 24 from the vehicle's central control panel cover. Step 4: Control the driving panel 22 to move up a second distance x2, and the left rod 2211 moves up and causes the left slider 23 to move diagonally leftward and upward, so that the left slider 23 is demolded from the car's central control panel cover; Step 5: Control the ejector plate 12 to move upward, and use the ejector pins 121 on the ejector plate 12 to extend upward from the surface of the lower mold core 11 to eject the car center console panel cover from the lower mold core 11; Step 6: Repeat steps 2-5 to continuously injection mold the automobile central control socket panel cover 200.

[0047] Specifically, in step 3, the driving panel 22 is moved up a first distance, and the transfer moving seat 251 can be moved obliquely to the left and upward through the action of the left side rod 2211, and the transfer slide 25 is linked to move obliquely to the left and downward along the sixth axis, and moves in a 72-degree inclined direction to complete the core pulling of the transfer slide 25; in step 4, the driving panel 22 is moved up a second distance x2, and the left side slide 23 can be moved obliquely to the left and upward through the action of the left side rod 2211, so that the left side slide 23 moves in a 70-degree inclined direction to complete the demoulding of the left side slide 23; with such a structure, the left side rod 2211 can be moved up the first distance x1 and the second distance x2 respectively by only the setting of one transfer moving seat 251, so as to realize demoulding at different angles of the transfer slide 25 and the left side slide 23, which can simplify the overall structure of the injection mold, and enhance the reliability of the injection mold by mechanically linking the slide movement, and does not require the setting of a hydraulic cylinder for control, thereby reducing the manufacturing cost of the injection mold.
