In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

In one preferred embodiment of the present application, as shown in fig. 2 to 19, an automobile upper trim panel mold comprises a fixed mold 3, a movable mold 2, a molding die set 5 and an ejection mechanism 4. The movable die 2 and the fixed die 3 are both vertically installed, so that the movable die 2 can be horizontally moved to be matched with and opened by the fixed die 3 under the driving of the driving device. The molding module 5 is installed on the fixed mold 3, and the molding module 5 can be matched with a concave cavity arranged on the movable mold 2 for injection molding of the upper decorative plate 100 when the mold is closed. The molding die set 5 includes a fixed die plate 51, a first movable core 52 and a second movable core 53, wherein the fixed die plate 51 is fixedly mounted to the fixed die 3, and the first movable core 52 and the second movable core 53 are respectively mounted to an upper portion and a lower portion of the fixed die plate 51, so that the first movable core 52 and the second movable core 53 respectively cooperate with the fixed die plate 51 for molding the clip 110 and the mount 120. The liftout mechanism 4 is installed in the fixed die 3, and the liftout mechanism 4 is connected with the first movable core 52 and the second movable core 53 respectively, so that when the movable die 2 is opened, the liftout mechanism 4 can drive the first movable core 52 and the second movable core 53 to perform the demolding process and the blanking process in sequence.

Wherein, the demoulding process: the liftout mechanism 4 drives the first movable core 52 to move up in an inclined manner, and simultaneously drives the second movable core 53 to move down in an inclined manner, so that the first movable core 52 and the second movable core 53 are demolded with the formed buckle and the mounting seat 120 respectively. The upper decorative plate 100 is always adhered to the second movable core 53 in the process of completing the demolding of the clip 110 and the mount 120, and then the blanking process is performed. The blanking process comprises the following steps: the ejector mechanism 4 may sequentially turn and deflect the upper plaque 100 attached to the second moving core 53. During the process of turning over the second moving core 53, the adhered upper trim panel 100 is changed from a vertical state at the time of molding to an inclined or horizontal state, and then during the deflection of the second moving core 53, the second moving core 53 is detached from the upper trim panel 100 so that the upper trim panel 100 is inclined or horizontally dropped by gravity to perform blanking.

It can be understood that, as shown in fig. 1, the cross-sections of the upper buckle 110 and the lower mounting seat 120 are L-shaped, and the directions of the buckle 110 and the mounting seat 120 are respectively toward the upper end and the lower end of the upper trim panel 100, so that the molded upper trim panel 100 is fastened to the fixed mold plate 51 through the buckle 110 and the mounting seat 120, and therefore, the upper trim panel 100 is difficult to be demolded conventionally, and needs to be demolded by a grabbing device such as a manipulator or to be blanked manually, and the grabbing device such as a manipulator is costly, and the grabbing device such as a manipulator is dangerous and labor-intensive.

When the upper decorative plate 100 is demolded, the first moving core 52 and the second moving core 53 can be driven by the liftout mechanism 4 to synchronously move up and down in an inclined manner, so that the upper decorative plate 100 adhered to the second moving core 53 can be simultaneously demolded by the buckle 110 and the mounting seat 120; this drawing of patterns process need not to use grabbing device such as manipulator, also need not the manual work simultaneously and operates. When the buckle 110 and the mounting seat 120 are demolded, the upper decorative plate 100 can be prevented from being interfered when being turned over in the subsequent blanking process. And through placing upper decoration board 100 in order to carry out the unloading with inclining or level, the impact force that produces when can effectual reduction upper decoration board 100 drops to guarantee upper decoration board 100's unloading quality.

It can also be understood that, if the upper decorative plate 100 is directly subjected to vertical blanking after being demolded, because the thickness of the upper decorative plate 100 is relatively thin and the force-bearing area on one side is small, when the upper decorative plate 100 is vertically dropped into the ground or the collecting device under the action of gravity, the impact force generated by gravity is likely to cause the lower end side wall of the upper decorative plate 100 to be damaged or worn, thereby reducing the blanking quality of the upper decorative plate 100. And through carrying out the unloading that inclines or level drops with last plaque 100, the lifting surface area after last plaque 100 drops will very big increase, and the air resistance at the in-process that drops also very big increase simultaneously, so the impact force of going up plaque 100 after the unloading obviously reduces to the quality after can guaranteeing the unloading of last plaque 100.

In this embodiment, as shown in fig. 4, 12 to 19, the ejector mechanism 4 includes an upper ejector rod 41 and a pair of lower ejector rod assemblies 42, the upper ejector rod 41 is disposed obliquely and penetrates through the fixed mold 3 and the fixed mold plate 51 to be connected to the first movable core 52; the lower mandril assemblies 42 are horizontally arranged at intervals and penetrate through the fixed die 3 and the fixed die plate 51 to be connected with the second movable core 53. Thus, when the demolding process is performed, the upper ejector rod 41 and the lower ejector rod assembly 42 respectively drive the first moving core 52 and the second moving core 53 to perform the obliquely upward movement and the obliquely downward movement, so that the clip 110 and the mount 120 on the molded upper trim panel 100 are respectively demolded from the first moving core 52 and the second moving core 53. When the blanking process is performed, the two lower ejector rod assemblies 42 can drive the second movable mold core 53 to turn over firstly, so that the formed upper decorative plate 100 is changed from a vertical state to an inclined or horizontal state; the two lower ram assemblies 42 are then blanked by rotating in opposite directions to cause the inclined or horizontally disposed upper trim panel 100 to become detached from the second moving core 53.

In this embodiment, as shown in fig. 5 and fig. 11 to fig. 13, the upper portion of the fixed die plate 51 is provided with a first mounting groove 510, the fixed die plate 51 is provided with a first forming groove 512 at a lower side of an end portion of the first mounting groove 510, and a specific number of the first forming grooves 512 may be set according to a number of the required fasteners 110 on the upper trim panel 100, for example, as shown in fig. 1 and fig. 5, the number of the first forming grooves 512 is two. The first movable core 52 is slidably mounted in the first mounting groove 510, and the side of the first movable core 52 is provided with first molding blocks 521 corresponding to the number and positions of the first molding grooves 512, so that when the mold is closed, the first molding blocks 521 can cooperate with the first molding grooves 512 to form a first molding cavity for molding the buckle 110. The bottom of the first mounting groove 510 is provided with a first through hole 511, and the inner end of the first movable core 52 is provided with a connecting hole 522, so that the upper ejector rod 41 can pass through the first through hole 511 and be connected with the connecting hole 522, so that during a demolding process, the first movable core 52 can be driven by the upper ejector rod 41 to move up and down along the axial direction of the upper ejector rod 41, and the first molding block 521 can be separated from the molded buckle 110.

It should be understood that the inner end of the first moving core 52 is an end surface close to the inside of the first mounting groove 510, and the inner upper side of the first mounting groove 510 is a slope, and the slope direction is the same as the slope direction of the upper ejector pin 41, so that the first moving core 52 can slide along the upper side wall of the first mounting groove 510 when the upper ejector pin 41 drives the first moving core 52 for demolding.

In one embodiment of the present application, as shown in fig. 5, 6, 8, and 14 to 19, a second installation groove 515 is disposed at one side of a lower portion of the fixed die plate 51, and a second forming groove 514 is disposed at an upper side of an end portion of the second installation groove 515 of the fixed die plate 51. The second moving core 53 comprises a first type core block 531, a second type core block 532 and a pair of blanking modules 533; wherein the first type core block 531 is slidably installed at one side of the inside of the second installation groove 515; the second type core block 532 is slidably mounted to the other side of the inside of the second mounting groove 515 while the side of the second type core block 532 is provided with a second molding block 5321 so that when the mold clamping is performed, the second type core block 532 can be fitted with the second molding groove 514 through the second molding block 5321 to form a second molding cavity for molding the mounting block 120. Meanwhile, the second core block 532 is respectively matched and connected with the first core block 531 and the second mounting groove 515, so that during the demolding process, the second core block 532 can be driven by the first core block 531 to move downwards and obliquely along the second molding groove 514, and the molded mounting seat 120 can be separated from the second molding block 5321.

One of the two blanking modules 533 is slidably mounted on the first core block 531, and the other is slidably mounted on the other side of the lower portion of the fixed die plate 51. After the upper decorative plate 100 is molded, the two blanking modules 533 can be adhered to the lower portion of the molded upper decorative plate 100. When the demolding process is performed, the first type core block 531 and the blanking module 533 are driven by the lower ejector rod assembly 42 to perform synchronous horizontal movement, so that the molded upper decorative plate 100 performs synchronous horizontal movement along with the blanking module 533, and at this time, the second type core block 532 is driven by the first type core block 531 to perform inclined downward movement along the second mounting groove 515, so that the molded mounting seat 120 can be separated from the second molding block 5321. Subsequently, during the blanking process, the first core block 531 remains stationary, so that the blanking module 533 can be separated from the first core block 531 and turned over under the continuous driving of the lower ejector rod assembly 42, so as to drive the adhered upper decorative plate 100 to be placed obliquely or horizontally, and then the two blanking modules 533 are driven again by the lower ejector rod assembly 42 to deflect in the opposite direction, so as to separate from the adhesion of the upper decorative plate 100 for blanking.

It can be understood that the lower portion of the upper decorative plate 100 is adhered to the two blanking modules 533, and when the upper decorative plate 100 is inclined or horizontal for blanking, the two blanking modules 533 deflect in opposite directions, so that both sides of the lower portion of the upper decorative plate 100 are simultaneously subjected to pull or pressure in opposite directions, and when the pull or pressure is greater than the adhesion force between the blanking modules 533 and the upper decorative plate 100, the upper decorative plate 100 is separated from the adhesion of the blanking modules 533 and falls off.

In this embodiment, as shown in fig. 8 and 9, the blanking module 533 is provided with a plurality of grooves 5330 on the outer end surface for molding the upper decorative plate 100, the grooves 5330 may be distributed in a staggered manner or arranged in order, and the grooves 5330 are elongated structures, so that the grooves 5330 can be firmly adhered to the outer end surface of the blanking module 533 during molding the upper decorative plate 100.

In this embodiment, as shown in fig. 6, 7, 8, 14, 16 and 19, a first stopper 516 is disposed in the middle of one side of the second mounting groove 515, and a second stopper 5311 is disposed on the bottom end side wall of the first core block 531; when the demolding process is performed, the first core block 531 can slide along the second installation groove 515 under the driving of the lower ejector rod assembly 42 until the first stopper 516 and the second stopper 5311 are in abutting fit, so that the first core block 531 is kept stationary during the subsequent blanking process.

The first positioning structure comprises a first positioning block 5313 and a second positioning sliding groove 5323 which are connected in a matched mode. The first positioning block 5313 is arranged on the extension block 5312, and the second positioning chute 5323 is arranged on the second type core block 532; or the first positioning block 5313 is disposed on the second type core block 532, and the second positioning sliding groove 5323 is disposed on the extension block 5312. When the first core block 531 moves horizontally, the second core block 532 can move synchronously with the first core block 531 through the first positioning structure, so that the second core block 532 can move with the first core block 531 for demoulding, and can also perform resetting and mould closing with the first core block 531.

In this embodiment, as shown in fig. 6, 8, 15 and 17, the second mounting groove 515 and the second type core block 532 are connected by a second positioning structure, and the second positioning structure includes a second positioning block 5322 and a first positioning sliding slot 517; the second positioning block 5322 is obliquely arranged on the second type core block 532, and the first positioning chute 517 is obliquely arranged on the second mounting groove 515; or the second positioning block 5322 is obliquely arranged in the second mounting groove 515, and the first positioning sliding slot 517 is obliquely arranged in the second type core block 532, so that the second type core block 532 can be obliquely moved downwards by the second positioning structure in the process of synchronous movement of the second type core block 532 along with the first type core block 531, and then the second molding block 5321 and the mounting seat 120 are demoulded.

It will be appreciated that the second positioning structure is provided at the lower end of the second mounting groove 515 and the second-type core block 532, which is located at a side of the second mounting groove 515 away from the second forming groove 514 and the second-type core block 532 away from the second forming block 5321.

In one embodiment of the present application, as shown in fig. 5 to 7, 10, 14, 16, 18 and 19, a pair of spaced second through holes 513 is disposed at a lower portion of the fixed die plate 51, wherein one second through hole 513 is communicated with the second mounting groove 515, and the other second through hole 513 is communicated with a position where the blanking module 533 away from the second mounting groove 515 is located. The two lower mandril assemblies 42 are correspondingly arranged in the two second through holes 513; the lower ejector rod assembly 42 comprises a lower ejector rod 421 and a connecting shaft 422, one end of the connecting shaft 422 is connected with the blanking module 533 in a matching manner, the other end of the connecting shaft 422 is hinged with one end of the lower ejector rod 421, the lower ejector rod 421 positioned in a second through hole 513 communicated with the second mounting groove 515 is sleeved with a spring 600, one end of the spring 600 is connected with the lower ejector rod 421, and the other end of the spring 600 is connected with the first type core block 531; meanwhile, the lower push rod 421 and the second through hole 513 are connected in a matching manner through a guide structure.

When the demolding process is performed, the lower ejector 421 performs a horizontal movement along the second through hole 513, so that the first type core block 531 performs a synchronous horizontal movement with the blanking module 533 under the elastic force of the spring 600. When the blanking process is performed, the first type core block 531 is in a static state, so that the blanking module 533 is separated from the first type core block 531 under the horizontal driving of the lower ejector rod 421, and the blanking module 533 further drives the adhered upper decorative plate 100 to turn downwards around the hinged position of the connecting shaft 422 and the lower ejector rod 421 under the action of gravity, so that the upper decorative plate 100 is in an inclined or horizontally placed state from a vertical state; subsequently, the two lower push rods 421 continue to move along the second through holes 513, so that the two lower push rods 421 reversely rotate under the guidance of the guide structure, and further, the blanking modules 533 hinged to the lower push rods are driven to synchronously deflect, and the upper decorative plate 100 and the two blanking modules 533 can be detached from the adhesive to perform blanking.

In this embodiment, as shown in fig. 7, 10, 14, 16, 18 and 19, the guiding structure includes a guiding block 4210 and a guiding sliding groove 518, the guiding sliding groove 518 includes a first guiding segment 5181 and a second guiding segment 5182, the first guiding segment 5181 is horizontally disposed, the second guiding segment 5182 is in deflection communication with the first guiding segment 5181, and the deflection directions of the second guiding segments 5182 in the two guiding structures are opposite. The guide block 4210 is arranged on the side wall of the lower top bar 421, and the guide sliding groove 518 is arranged on the side wall of the second through hole 513; or the guide block 4210 is arranged on the side wall of the second through hole 513, and the guide sliding groove 518 is arranged on the side wall of the lower top bar 421. Therefore, during the process of demoulding and turning over the upper plaque 100, the guide block 4210 can slide along the first guide section 5181, so that the lower ejector rod 421 can horizontally move; when the upper decorative plate 100 is blanked, the guide block 4210 can be in sliding fit along the second guide section 5182, so that the two lower ejector rods 421 rotate in opposite directions, and further the two blanking modules 533 are driven to deflect reversely to detach and adhere the upper decorative plate 100.

It will be appreciated that the second guide segments 5182 of the two guide structures can be biased toward each other or away from each other. If the two second guide sections 5182 are deflected towards each other, as shown in fig. 19, the two lower lift pins 421 can drive the two blanking modules 533 of (a) and (b) in fig. 19 to deflect back, so as to generate pulling forces on the upper decorative plate 100 in opposite directions. If the two second guiding sections 5182 are deflected away from each other, the two lower push rods 421 can drive the two blanking modules 533 to generate opposite pressures on the upper decorative plate 100. No matter the generated pulling force or pressure is greater than the adhesion force between the upper decoration plate 100 and the blanking module 533, the upper decoration plate 100 can be detached from the blanking module 533 for dropping and blanking.

In this embodiment, as shown in fig. 9, 10, 14, 16 and 18, the inner end of the blanking module 533 is provided with an opening 5332 communicated with the inner cavity 5331, the size of the opening 5332 is smaller than that of the inner cavity 5331, and the side wall of the opening 5332 is provided with a spline groove. The side of the connecting shaft 422 is provided with a spline, the connecting shaft 422 can be connected with the spline groove in a matching manner through the spline, and meanwhile, the end of the connecting shaft 422 extending to the inner cavity 5331 is in sliding fit with the inner cavity 5331 through the connecting block 4220, so that when the lower ejector rod 421 drives the first type core block 531 to horizontally move through the spring 600, the connecting shaft 422 provides a certain compression space for the spring 600 through sliding along the inner cavity 5331, and further, the spring 600 is ensured to have enough elasticity to drive the first type core block 531 and the blanking module 533 to synchronously move.

It can be understood that after the first core block 531 completes the injection molding of the upper trim panel 100, a certain fastening force exists between the first core block 531 and the second mounting groove 515, so that when the lower ejector pin 421 drives the first core block 531 to move through the spring 600 for demolding, the lower ejector pin 421 moves a distance because the fastening force is greater than the elastic force of the spring 600 within an initial certain distance, but the first core block 531 is stationary, and the blanking module 533 slides relatively, and then drives the upper trim panel 100 to move synchronously, so that the mounting seat 120 is broken by the second molding block 5321. Therefore, by providing the inner cavity 5331 in the blanking module 533, the lower push rod 421 can drive the connecting shaft 422 to slide along the inner cavity 5331 under the condition that the spring 600 does not drive the first type core block 531 when moving for a certain distance, so as to ensure that the blanking module 533 is also in a static state at this time.

Meanwhile, the spline connection between the connecting shaft 422 and the blanking module 533 can ensure that the lower ejector pin 421 can drive the blanking module 533 to deflect synchronously through the connecting shaft 422 when rotating. Of course, in order to achieve the above functions, there are various structures between the connecting shaft 422 and the blanking module 533, for example, the cross sections of the connecting shaft 422 and the opening 5332 may be rectangular or elliptical.

Through the size that is less than inner chamber 5331 with opening 5332's size setting, can guarantee that blanking module 533 is connected with connecting axle 422 all the time to can drive connecting axle 422 through lower ejector pin 421 and drive blanking module 533 and overturn and deflect and carry out the unloading, lower ejector pin 421 can also drive blanking module 533 through connecting axle 422 simultaneously and reset the compound die.

In this embodiment, in order to facilitate the resetting and mold closing of the blanking module 533, the inner end side of the blanking module 533 is tapered or rounded.

The whole blanking process of the upper decorative plate 100 of the application is as follows: after the upper decorative plate 100 is injection molded, the movable mold 2 is horizontally away from the fixed mold 3 to open the mold. The lower lift bar 421 may be moved a distance first so that the elastic force of the spring 600 is just equal to the fastening force of the first type core block 531 and the second mounting groove 515, and then the upper lift bar 41 and the lower lift bar 421 are moved in synchronization, and the synchronized movement of the upper lift bar 41 and the lower lift bar 421 may be detected and controlled by a sensor. Therefore, the lower push rod 421 drives the upper decorative plate 100 to move horizontally by driving the blanking module 533, and simultaneously, the upper push rod 41 and the lower push rod 421 respectively drive the first movable core 52 and the second core block 532 to move up and down obliquely, until the first molding block 521 and the second molding block 5321 are respectively separated from the buckle 110 and the mounting seat 120 on the upper decorative plate 100. When the second molding block 5321 is disengaged from the mounting seat 120, the first molding block 531 is just in abutting contact with the second stopper 5311 and the first stopper 516, so that the first type core blocks 531 remain stationary in the subsequent process, and then the lower top bar 421 continues to drive the blanking module 533 to horizontally move until the blanking module 533 installed in the first type core blocks 531 is separated from the first type core blocks 531, so that the blanking module 533 is turned over around the hinged position of the connecting shaft 422 under the action of gravity, at this time, the guide block 4210 in the guide structure between the lower top bar 421 and the second through hole 513 just moves to the end of the first guide section 5181, i.e., the initial position of the second guide section 5182, so that the lower push rod 421 rotates under the continuous sliding of the guide block 4210 along the second guide section 5182, thereby driving the blanking module 533 to deflect synchronously to separate from the upper decorative plate 100.

Resetting: after the upper decorative plate 100 is completely blanked, the upper ejector rod 41 can directly drive the first movable core 52 to perform reverse movement resetting. The lower top rod 421 also performs reverse movement, and during the reverse movement of the lower top rod 421, the lower top rod firstly slides to the first guide section 5181 along the second guide section 5182 through the guide block 4210, so that the blanking module 533 performs reverse deflection resetting, and then the blanking module 533 is driven by the lower top rod 421 to perform reverse inversion resetting and shrink into the first type core block 531 through the sliding of the side wall along the edge of the installation position in the first type core block 531, so as to drive the first type core block 531 to be synchronously reset into the second installation groove 515, and meanwhile, the resetting of the first type core block 531 can drive the second type core block 532 to be synchronously reset into the second installation groove 515 through the first positioning structure and the second positioning structure.
