Description

Technical Field

[0001] The present application relates to the technical field of mold forming and demoulding, and in particular to a large mold assembly downhill inclined roof structure. Background Art

[0002] The car dashboard is the installation carrier of various control components in modern cars. It is a vital part in car manufacturing and assembly. The dashboard is presented to the driver and passengers, and its beauty directly reflects the overall quality of the car. Therefore, the importance of the dashboard itself is self-evident.

[0003] With the rapid development of the automotive industry, the structure of the instrument panel is becoming more and more complex, and the requirements for product quality are becoming higher and higher. Figure 1 This is a large automotive instrument panel. The instrument panel includes a main body and a side flange attached to one side of the main body. The side flange forms an angle with the instrument panel body that is less than 90 degrees. Existing molds use conventional inclined ejector sliders to eject products. However, because the extension direction of the side flange intersects with the ejection direction, the side flange is easily damaged during ejection, reducing the product qualification rate. Utility Model Content

[0004] In order to reduce the probability of damage to the side flanges of large automobile instrument panels during ejection from a mold, the present application provides a large mold assembly with a downhill inclined ejection structure.

[0005] The present application provides a large mold assembly downhill inclined roof structure adopting the following technical solutions:

[0006] A large mold combination downhill inclined ejector structure includes a fixed base plate, a core arranged on the top of the lower mold, and an ejection mechanism arranged on the lower mold and used to eject the product. The lower mold also includes multiple groups of inclined ejector mechanisms for assisting in the ejection of side flanges. The inclined ejector mechanism includes an inclined ejector block for forming one side of the side flange, an inclined ejector slide that slides synchronously with the ejection mechanism, an inclined ejector slider arranged on the inclined ejector slide for oblique sliding, and an inclined ejector rod connecting the inclined ejector slider and the inclined ejector block. The inclined ejector head is located on the side of the side panel flange facing the instrument panel. When the ejection mechanism rises, the inclined ejector slider moves away from the side flange.

[0007] By adopting the above technical solution, when the ejection mechanism starts to eject the product, the inclined ejector slide and the ejection mechanism rise synchronously, and the inclined ejector slide is arranged at an angle, so that the inclined ejector slide gradually slides away from the side flange when rising, and drives the inclined ejector rod and the inclined ejector block to be staggered with the side flange in the horizontal direction, so that the product can be smoothly ejected and demolded from the vertical direction. The setting of the inclined ejector mechanism can protect the ejection of the product and improve the product yield. At the same time, the ejection and inclined ejection are combined to improve the unloading efficiency of the product.

[0008] Optionally, the bottom of the lift rod passes through the lift slide, and the lift rod is provided with a cooling joint at the bottom, the lift rod has a cooling channel connected to the lift block, and the lift block has a cooling flow channel.

[0009] By adopting the above technical solution, the provision of the cooling joint and the cooling channel facilitates the delivery of the coolant to the cooling channel of the inclined ejector block, thereby improving the cooling and forming efficiency of the side flanging.

[0010] Optionally, the tilting lift mechanism also includes an auxiliary component, which includes a fixed seat arranged on the fixed base plate, an auxiliary rod obliquely fixed to the fixed seat, and an auxiliary slider sleeved on the auxiliary rod, the auxiliary slider is fixedly connected to the tilting lift slider, and the inclination angle of the auxiliary rod is consistent with that of the tilting lift rod.

[0011] By adopting the above technical solution, the setting of the auxiliary components plays a guiding and supporting role, thereby improving the stability of the overall movement of the lift mechanism and reducing the probability of loosening or deformation of the lift rod and the lift block.

[0012] Optionally, the side walls of the inclined top slider and the auxiliary slider are both provided with connecting columns, and connecting plates are plugged into the connecting columns, and the inclined top slider and the auxiliary slider are fixed by the connecting plates.

[0013] By adopting the above technical solution, the connecting plate is inserted into the connecting column of the inclined top slider and the auxiliary slider to fix the two sliders. The connection method is simple and the assembly efficiency of the auxiliary component and the inclined top slider is improved.

[0014] Optionally, the inclined top slide seat is provided with a sliding groove for the inclined top slider and the auxiliary slider to slide, the bottom wall of the sliding groove has a penetration hole that passes through the upper and lower end faces and for the auxiliary rod and the inclined top rod to pass through, and the connecting plate is limited to abut against the side wall of the sliding groove.

[0015] By adopting the above technical solution, compared with only setting the inclined top slider on the inclined top slide, the inclined top slider and the auxiliary slider are both slidably installed on the inclined top slide, which can further improve the stability of the inclined top mechanism.

[0016] Optionally, the fixing seat is provided with a fixing countersunk hole for inserting the auxiliary rod, the end of the auxiliary rod is limitedly engaged with the fixing countersunk hole, and the fixing seat is provided with a clamping block in the fixing countersunk hole for clamping the auxiliary rod.

[0017] By adopting the above technical solution, a matching method of the auxiliary rod and the fixing seat is disclosed. The auxiliary rod passes through one end of the fixing countersunk hole, and then the pressing block is fixed in the fixing countersunk hole, thereby improving the stability of the bottom of the auxiliary rod.

[0018] Optionally, the lower mold is provided with five groups of the inclined ejection mechanisms, and the inclined ejection blocks of the five groups of the inclined ejection mechanisms are arranged adjacent to each other, and the size of the inclined ejection blocks located on both sides is smaller than that of the middle inclined ejection block.

[0019] By adopting the above technical solution, the number of inclined ejector mechanisms is specifically limited, and the overall inclined ejector block is divided into multiple inclined ejector blocks, the mold structure can be optimized and the manufacturing cost of the mold can be reduced. The setting of multiple inclined ejector blocks can more effectively disperse the ejection pressure and improve the demoulding efficiency.

[0020] Optionally, the inclined ejector block is further provided with an anti-elevation assembly that abuts the side flange, and the anti-elevation assembly includes an anti-elevation rod slidably installed on the inclined ejector block, an elastic member sleeved on the anti-elevation rod, and a limit block for limiting the sliding of the anti-elevation rod. One end of the anti-elevation rod passes through the inclined ejector block and abuts against the side flange, and the anti-elevation rod is driven by the elastic member to have a tendency to separate from the side flange.

[0021] By adopting the above technical solution, the setting of the anti-top assembly can enable the anti-top rod to separate from the side flange under the action of the elastic member when the inclined top block moves away from the side flange, providing reverse thrust for the side flange, thereby reducing the probability of the side flange being stretched due to adhesion to the inclined top block.

[0022] Optionally, the inclined ejector block is provided with a mounting countersunk hole for installing the elastic member, the side wall of the anti-elevator rod has a limiting ring for abutting one end of the elastic member, the limiting block is located on the side of the limiting ring away from the elastic member, and is fixedly connected to the inclined ejector block.

[0023] By adopting the above technical solution, an installation method of the elastic part is disclosed, in which the two ends of the elastic part respectively abut against the limit ring and the bottom wall of the mounting countersunk hole. The elastic part provides the anti-thrust rod with a force to move away from the side flange, and the limit block can limit the sliding distance of the anti-thrust block.

[0024] Optionally, a side slider for forming the other side of the side flanging and a sliding driving member for driving the side slider are also slidably provided on the core.

[0025] By adopting the above technical solution, the side slider is used to form the other side of the side flange. When the product is demoulded, the side slider is first moved away from the side flange by the sliding drive component, and then the ejection mechanism is started.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. The present application adopts the arrangement of the inclined ejector mechanism, so that when the ejector mechanism ejects the product, it simultaneously drives the inclined ejector block away from the side flange, thereby improving the efficiency of ejecting the product from the vertical direction;

[0029] 3. Through the provision of the anti-thrust assembly, the present application enables the anti-thrust rod to separate from the side flange under the action of the elastic member when the inclined ejection block moves away from the side flange, thereby reducing the probability of the side flange being stretched due to adhesion to the inclined ejection block.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] The embodiment of the present application discloses a large mold assembly with a downhill inclined roof structure.

[0039] Reference Figure 1 A large mold assembly with a downhill inclined ejector structure comprises a fixed base plate 1, a lower mold core (not shown) mounted on top of the lower mold, an ejection mechanism 2 mounted on the lower mold for ejecting the product, and an inclined ejection mechanism 3 that rises and falls synchronously with the ejection mechanism 2. The fixed base plate 1 is rectangular and placed horizontally on the work surface, remaining stationary. Mold feet 11 are fixed to the four corners of the fixed base plate 1, and the lower mold core is fixed to the top of the mold feet 11.

[0040] The ejector mechanism 2 includes a push plate 21 that slides between the fixed base plate and the lower core, and an ejector cylinder 22 fixed to the core and used to drive the push plate 21 up and down. A plurality of ejector pins (not shown) are fixed to the top of the push plate 21 for ejecting the instrument panel body.

[0041] Reference Figure 2 and Figure 3 The tilting mechanism 3 is used to form the side flange 62 close to the instrument panel body and cooperates with the ejection mechanism 2 to assist in ejecting the product. The tilting mechanism 3 includes a tilting block 31, a tilting slide 32, a tilting slider 33, a tilting rod 34 and an auxiliary component 35.

[0042] Reference Figure 1 The cavity is also provided with a side slider 4 corresponding to the inclined ejector block 31 and used to form the other side of the side flange 62. A sliding drive 5 is fixedly mounted on the side wall of the cavity to drive the side slider 4 to slide obliquely. The sliding drive 5 is a hydraulic cylinder. When the ejection mechanism 2 is demolded, the sliding drive 5 first separates the side slider 4 from the side flange 62.

[0043] The lifter block 31 is located in the mold cavity. Due to the long side flange 62 that needs to be formed, the production cost of a single lifter block 31 is high, and the pressure exerted on each lifter block 31 is high, affecting the product's demolding efficiency. Therefore, in this embodiment, the lower mold is equipped with five sets of mutually abutting lifter blocks 31, each with an independent lifter mechanism 3. The lifter blocks 31 on both sides are smaller in size than the lifter block 31 in the center, and the lifter block 31 in the center is equipped with two sets of lifter rods 34.

[0044] The inclined lift slide 32 is a rectangular block, bolted to the top of the push plate 21 at an angle. A sliding groove 321 is defined in the inclined lift slide 32, into which the inclined slide block 33 slides. The groove 321 also has an inclined cross-section in the height direction, sloping upward from the instrument panel body 61 to the side flange 62. During product molding, the inclined slide block 33 is located at the top of the inclined groove 321.

[0045] The bottom wall of the sliding groove 321 has holes 322 extending through the upper and lower end surfaces. One end of the lift rod 34 is fixed to the bottom of the lift block 31, while the other end extends through the lift slider 33 to the bottom of the lift slide 32. The lift rod 34 has an inclined vertical cross-section, tilting upward toward the instrument panel body 61. The specific angle of inclination is determined by the angle between the side flange 62 and the instrument panel 6.

[0046] Combine Figure 5 The bottom of the lift block 31 has a socket 311 for inserting the top end of the lift rod 34. The side wall of the lift block 31 has a connecting hole 312 connected to the socket 311. The lift block 31 has an abutment block 313 bolted to the connecting hole 312. The abutment block 313 presses the lift rod 34 tightly to secure the lift block 31 and the lift rod 34.

[0047] The lift slider 33 is sleeved onto the lift rod 34. The sidewall of the lift rod 34 has a stopper surface 341 against which the top of the lift slider 33 abuts. A compression sleeve 342 is also sleeved on the bottom of the lift rod 34. A nut is threadedly mounted on the bottom of the compression sleeve 342 of the lift rod 34, which presses the compression sleeve 342 against the bottom of the lift slider 33. The compression sleeve 342 and the stopper surface 341 securely connect the lift slider 33 and the lift rod 34.

[0048] The lift rod 34 has a cooling channel 343 along its axis, and the lift block 31 has a cooling channel 314 in communication with the top of the cooling channel 343. A cooling joint 344 is provided at the bottom of the lift rod 34 for connecting to a cooling medium.

[0049] The auxiliary component 35 includes a fixed seat 351, an auxiliary rod 352 and an auxiliary slider 353. The fixed seat 351 is fixedly arranged on the fixed base plate 1, and the bottom of the fixed base plate 1 has a countersunk hole for the installation of the fixed seat 351. The fixed seat 351 is provided with a fixed countersunk hole 3511 for the auxiliary rod 352 to pass through, and the bottom of the auxiliary rod 352 is limitedly engaged with the fixed countersunk hole 3511. The fixed countersunk hole 3511 is arranged obliquely in the vertical direction, and its inclination angle is consistent with the inclined push rod 34. The fixed seat 351 is also provided with a clamping block 3512 at the fixed countersunk hole 3511. The clamping block 3512 is fixedly connected to the fixed seat 351 by bolts, so as to improve the connection stability between the auxiliary rod 352 and the fixed seat 351.

[0050] The auxiliary slider 353 is slidably mounted on the auxiliary rod 352. The auxiliary slider 353 is fixedly connected to the tilting slider 33, and both are located on the tilting slider 32. The auxiliary slider 353 is lower than the tilting slider 33. Connecting posts 3531 are integrally formed on the opposing side walls of the auxiliary slider 353 and the tilting slider 33. The two sliders are secured together by a connecting plate 36. The connecting plate 36 and the connecting posts 3531 are plugged into each other. The sliding groove 321 of the tilting slider 32 has a T-shaped cross-section in the height direction. The connecting plates 36 on either side of the two sliders abut the side walls of the sliding groove 321.

[0051] When the push plate 21 moves upward, it drives the inclined top slide 32, the inclined top slider 33, and the auxiliary slider 353 to rise synchronously. Under the action of the inclined sliding groove 321, the inclined top slider 33 and the auxiliary slider 353 both move toward the inclined lower end of the sliding groove 321, that is, it drives the inclined top rod 34 and the inclined top block 31 to move in the direction away from the side flange 62, so that the inclined top block 31 and the side flange 62 gradually separate from the abutment state.

[0052] Reference Figure 6 To reduce the risk of sticking and tearing during demolding, the inclined ejector block 31 is equipped with a counter-ejection assembly 37 that abuts the side flange 62. This assembly 37 includes a counter-ejection rod 371, an elastic member 372, and a stopper 373. The inclined ejector block 31 has a stopper counterbore 315 for mounting the counter-ejection assembly 37. One end of the stopper counterbore 315 connects to the mold cavity. The counter-ejection rod 371 is inserted into the stopper counterbore 315, with one end abutting the side flange 62.

[0053] The elastic member 372 is a compression spring, which is sleeved on the anti-thrust rod 371. One end of the elastic member 372 abuts the bottom wall of the limiting counterbore 315, and the side wall of the anti-thrust rod 371 is integrally provided with a limiting ring for the other end of the elastic member 372 to abut. The limiting block 373 is provided on the side of the limiting ring away from the elastic member 372, and is fixedly connected to the inclined ejector block 31 by bolts. When the product is molded, the compression spring is in a compressed state. When the product is demolded and ejected, the inclined ejector block 31 moves away from the side flange 62, causing the compression spring to recover its deformation, and the anti-thrust rod 371 to detach from the side flange 62 and provide a reverse thrust for the side flange 62, thereby reducing the probability of the side flange 62 being stuck to the inclined ejector block 31 and being strained.

[0054] The implementation principle of the downhill inclined ejector structure of a large mold combination in the embodiment of the present application is as follows: after the product is formed and cooled, the side slider 4 is first separated from the side flange 62 by the sliding drive part 5, and then the ejection cylinder 22 is started to drive the push plate 21 to rise, and the inclined ejector slider 33 and the auxiliary slider 353 slide toward the inclined bottom of the inclined ejector slide 32 while rising, driving the inclined ejector rod 34 and the inclined ejector block 31 to move away from the side flange 62, so that the inclined ejector block 31 and the side flange 62 are staggered, thereby enabling the ejection mechanism 2 to push the product vertically out in the height direction.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
