Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to a car refueling base mold and its molding method. Background Technology

[0002] Injection molding is a common process for manufacturing plastic parts such as car fuel filler caps. On automated production lines, after the product is opened in the static and dynamic molds, it is usually ejected from the core plate by an ejector mechanism, and then picked up and removed by a robotic arm.

[0003] As a permanent protective interface installed at the fuel tank opening of a car, the fuel filler seat is usually made of oil-resistant and impact-resistant engineering plastic through injection molding. Its structure consists of a threaded or snap-on base that matches the fuel tank opening. The inner wall of the fuel filler seat needs to fit tightly with the sealing ring of the vehicle's fuel tank cap to ensure that the fuel system maintains good airtightness during the filling process and prevent fuel leakage.

[0004] However, when the ejector pin lifts the car fuel dispenser, the product remains on the ejector pin end face. Due to cooling, the product shrinks and covers the ejector pin end. If the product is forcibly removed at this time, the inner wall of the product will be scratched and deformed, affecting the yield of the product. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the present invention aims to provide a car refueling station mold and molding method, which has the advantage of tilting the car refueling station product during the material handling process to avoid scratches.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This invention provides a car refueling base mold, including a moving template and a fixed template. A cavity plate is mounted on the moving template, and a core plate adapted to the cavity plate is mounted on the fixed template. When the mold is closed, the gap between the cavity plate and the core plate forms a molding cavity for the car refueling base product. The car refueling base product has a hinge mounting part and a locking mounting part. Several vertical ejector pins are slidably connected on the fixed template. A hollow mounting box is fixed to the outer wall of the fixed template. A crossbar is slidably connected to the mounting box. After the mold is opened and the ejector pin moves upward to complete the ejection and demolding of the car fuel base product, the end of the crossbar moves to one of the ejector pin positions corresponding to the locking mounting part, and is located between the core plate and the car fuel base product. A pushing mechanism is provided at the end of the crossbar, which causes the car refueling base product to rotate around its hinge mounting position, thereby tilting the car refueling base product.

[0007] By adopting the above technical solution, and by setting a pushing mechanism at the ejector pin position corresponding to the locking mounting part, the car fuel base product is tilted after demolding. The locking mounting part of the car fuel base product is raised, so that the car fuel base product is separated from most of the ejector pin contact surface. This reduces the possibility of scratching and deformation caused by the car fuel base product sticking to the ejector pin when the robot arm picks up the part, thereby improving the production yield and mold maintenance cycle.

[0008] The method of using a multi-axis robot to tilt the car refueling base product after grasping it, and then removing it, places high demands on the performance of the robot and increases the production cost. However, this application adjusts the car refueling base product to a tilted state before contacting the robot, which reduces the performance requirements of the robot. It only needs to have simple gripping and linear removal functions, and its economy and versatility make it suitable for large-scale automated production.

[0009] Preferably, the outer wall of the ejector pin corresponding to the locking mounting part is provided with a slot, and the top wall of the slot is integrally formed with a vertical pressure block, and a gap is formed between the vertical pressure block and the slot for the insertion of the end of the crossbar; the side of the vertical pressure block near the mounting box is inclined.

[0010] Preferably, the pushing mechanism includes a fixed shaft fixed to the end of the crossbar. A first sleeve and a second sleeve are rotatably sleeved on the fixed shaft. An L-shaped pressure rod that can be pressed down by a vertical pressure block and a first swing rod are fixedly connected to the first sleeve. An L-shaped top rod for lifting the product and a third swing rod are fixedly connected to the second sleeve. The first swing rod and the third swing rod are linked by a connecting component. When the L-shaped pressure rod is pressed down, the L-shaped top rod rotates in the opposite direction synchronously to lift the locking mounting part.

[0011] Preferably, the connecting assembly includes an outer sleeve fixed to the crossbar, a limiting inner tube slidably connected inside the outer sleeve, and the outer sleeve and the limiting inner tube connected by a spring; a second swing rod is hinged to the end of the first swing rod, and a fourth swing rod is hinged to the end of the third swing rod; two oppositely arranged and communicating strip grooves are formed on the outer wall of the outer sleeve, and a short shaft is slidably connected in each strip groove, one end of the short shaft is fixed to the limiting inner tube, and the other end extends out of the strip groove and is hinged to the adjacent second or fourth swing rod; the second and fourth swing rods rotate in opposite directions, thereby causing the L-shaped pressure rod and the L-shaped top rod to rotate in opposite directions.

[0012] Preferably, the moving template is provided with a drive assembly on which a drive crossbar extends into the space between the car refueling base product and the core plate after the mold is opened.

[0013] Preferably, the drive assembly includes an active rack connected to the moving template, the active rack being connected to a driven rack via a cooperating acceleration gear set, the driven rack being slidably connected to the mounting box groove wall via a slide rail, a connecting seat being fixed at the end of the driven rack, and the crossbar passing through the connecting seat and being able to slide up and down relative to the connecting seat.

[0014] Preferably, the inner cavity of the mounting box is further fixed with a mounting plate. The mounting plate has a guide groove formed by a continuous horizontal section and an inclined section. A connecting shaft passes through the guide groove. A roller that is slidably connected to the guide groove is coaxially nested on the connecting shaft. The connecting shaft passes through the mounting plate and is fixed to the crossbar. When the connecting seat drives the crossbar to move horizontally, the connecting shaft slides along the horizontal section of the guide groove. When the connecting shaft moves to the inclined section of the guide groove, the crossbar generates a vertical displacement relative to the connecting seat under the guidance of the connecting shaft.

[0015] Preferably, the moving template is provided with a delay mechanism.

[0016] Preferably, the delay mechanism includes a long rod fixed to the outer wall of the moving template, a vertical strip groove running through the long rod, a movable block slidably connected in the strip groove, a bracket fixed to one end of the movable block extending out of the long rod, and the end of the bracket away from the slider fixed to the active rack.

[0017] A method for molding a car fuel filler base includes the following steps: Step S1 Mold Closure Injection: Drive the moving mold plate and the fixed mold plate to close the mold, so that the cavity plate and the core plate together form a molding cavity, and inject molten plastic into it to form the car refueling base product; Step S2: Mold opening and ejection of the car fuel filler base product: Drive the moving platen and the fixed platen to separate the mold to open the mold, and then drive several ejector pins to move upward to separate the car fuel filler base product from the core plate; Step S3: Adjust the posture of the car refueling base: Insert the crossbar into the slot position of the corresponding pin in the locking mounting part and move it upward, so that the car refueling base rotates around its hinge mounting part area and presents a tilted posture. Step S4: Remove the tilted car refueling base product.

[0018] The beneficial effects of this invention are as follows: by setting a pushing mechanism at the ejector pin position corresponding to the locking mounting part, the car fuel base product is tilted after demolding, and the locking mounting part of the car fuel base product is raised, so that the car fuel base product is disconnected from most of the ejector pin contact surfaces, reducing the possibility of scratching and deformation caused by the car fuel base product sticking to the ejector pin when the robot arm picks up the part, thereby improving the production yield and mold maintenance cycle.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] A car refueling station mold and molding method, such as Figure 1-8 The mold includes a moving mold plate 1 and a fixed mold plate 2. A cavity plate is mounted on the moving mold plate 1, and a core plate 21 adapted to the cavity plate is mounted on the fixed mold plate 2. When the mold is closed, the gap 43 between the cavity plate and the core plate 21 forms the molding cavity of the car fuel base product 3. The car fuel base product 3 has a hinge mounting part 31 and a locking mounting part 32. Several vertical ejector pins 4 are slidably connected on the fixed mold plate 2. A hollow mounting box 5 is fixed to the outer wall of the fixed template 2. A crossbar 6 is slidably connected to the mounting box 5. After the mold is opened and the ejector pin 4 moves upward to complete the ejection and demolding of the car fuel base product 3, the end of the crossbar 6 moves to one of the ejector pin 4 positions corresponding to the locking mounting part 32, and is located between the core plate 21 and the car fuel base product 3. A pushing mechanism 7 is provided at the end of the crossbar 6. The pushing mechanism 7 causes the car refueling base product 3 to rotate around its hinge mounting part 31, thereby tilting the car refueling base product 3.

[0024] In the above design, by setting a pushing mechanism 7 at the position of the ejector pin 4 corresponding to the locking mounting part 32, the car fuel base product 3 is tilted after demolding, and one side of the locking mounting part 32 of the car fuel base product 3 is raised, so that the car fuel base product 3 is disconnected from most of the contact surface of the ejector pin 4. This reduces the possibility of scratching and deformation caused by the car fuel base product 3 sticking to the ejector pin 4 when the robot arm picks up the part, thereby improving the production yield and mold maintenance cycle.

[0025] If a multi-axis robot is used to tilt the car refueling base product 3 after grasping it, and then remove the car refueling base product 3, the performance requirements of the robot are high, which increases the production cost of the product. However, this application adjusts the car refueling base product 3 to a tilted state before contacting the robot, which reduces the performance requirements of the robot. It only needs to have simple gripping and linear removal functions. Its economy and versatility are suitable for large-scale automated production.

[0026] The core plate 21 has a through hole corresponding to the ejector pin 4. When the mold is closed, the top of the ejector pin 4 is flush with the top opening of the through hole. The movement of the ejector pin 4 is existing technology, so it will not be described in detail here.

[0027] like Figure 8As shown, a slot 41 is provided on the outer wall of the ejector pin 4 corresponding to the locking mounting part 32. A vertical pressure block 42 is integrally formed on the top wall of the slot 41. A gap 43 is formed between the vertical pressure block 42 and the slot 41 for the insertion of the end of the crossbar 6. The side of the vertical pressure block 42 near the mounting box 5 is inclined to guide the L-shaped pressure rod 74 to contact the vertical pressure block 42. After the crossbar 6 is inserted between the locking mounting part 32 and the core plate 21, the crossbar 6 will insert into the slot 41. When the crossbar 6 moves upward, it extends into the gap 43.

[0028] like Figure 4 and Figure 7 As shown, the pushing mechanism 7 includes a fixed shaft 71 fixed to the end of the crossbar 6. A first sleeve 72 and a second sleeve 73 are rotatably sleeved on the fixed shaft 71. An L-shaped pressure rod 74 that can be pressed down by the vertical pressure block 42 and a first swing rod 75 are fixedly connected to the first sleeve 72. An L-shaped top rod 76 for lifting the product and a third swing rod 77 are fixedly connected to the second sleeve 73. The first swing rod 75 and the third swing rod 77 are linked by a connecting component. When the L-shaped pressure rod 74 is pressed down, the L-shaped top rod 76 rotates in the opposite direction synchronously, lifting the locking mounting part 32.

[0029] After the horizontal bar 6 moves upward, the vertical pressure block 42 presses down on the long side of the L-shaped pressure bar 74. The swing of the L-shaped pressure bar 74 is transmitted through the first sleeve 72, the first swing rod 75, the connecting component, the third swing rod 77 and the second sleeve 73, which drives the L-shaped top rod 76 to rotate synchronously in the opposite direction, lifting the locking mounting part 32, which facilitates the removal of materials from the car refueling base product 3.

[0030] like Figure 4 and Figure 7 As shown, the connecting assembly includes an outer sleeve 78 fixed to the crossbar 6, a limiting inner tube 79 slidably connected inside the outer sleeve 78, and the outer sleeve 78 and the limiting inner tube 79 are connected by a spring; a second swing rod 710 is hinged to the end of the first swing rod 75, and a fourth swing rod 711 is hinged to the end of the third swing rod 77; two oppositely arranged and communicating strip grooves 712 are opened on the outer wall of the outer sleeve 78, and a short shaft 713 is slidably connected in each strip groove 712. One end of the short shaft 713 is fixed to the limiting inner tube 79, and the other end extends out of a strip groove 92 and is hinged to the adjacent second swing rod 710 or fourth swing rod 711; the rotation directions of the second swing rod 710 and the fourth swing rod 711 are opposite, thereby causing the rotation directions of the L-shaped pressure rod 74 and the L-shaped top rod 76 to be opposite.

[0031] The moving template 1 is equipped with a drive crossbar 6 that extends into the drive assembly 8 between the car refueling base product 3 and the core plate 21 after the mold is opened.

[0032] like Figure 5 and Figure 6As shown, the drive assembly 8 includes an active rack 81 connected to the moving template 1. The active rack 81 is connected to a driven rack 86 through a cooperating acceleration gear set. The driven rack 86 is slidably connected to the groove wall of the mounting box 5 through a slide rail. A connecting seat 87 is fixed at the end of the driven rack 86. The crossbar 6 passes through the connecting seat 87 and can slide up and down relative to the connecting seat 87.

[0033] like Figure 5 and Figure 6 As shown, the acceleration gear set includes a drive shaft 82, with both ends of the drive shaft 82 fixed to the inner cavity wall of the mounting box 5. A drive gear 83, coaxially fixed to the drive shaft 82, is nested outside the drive shaft 82. The drive gear 83 meshes with the drive rack 81. A follower gear 84, coaxially fixed to the drive shaft 82, is also nested outside the drive shaft 82. A driven shaft is provided above the drive shaft 82, with both ends of the driven shaft fixed to the inner cavity wall of the mounting box 5. A driven gear 85, coaxially fixed to the driven shaft, is nested outside the driven shaft. The driven gear 85 meshes with the follower gear 84 and the driven gear 85 meshes with the driven rack 86.

[0034] like Figure 5 and Figure 6 As shown, an installation plate 88 is also fixed inside the mounting box 5. The installation plate 88 has a guide groove 89 formed by a horizontal section and an inclined section. A connecting shaft 810 passes through the guide groove 89. A roller that is slidably connected to the guide groove 89 is coaxially nested on the connecting shaft 810. The connecting shaft 810 passes through the installation plate 88 and is fixed to the crossbar 6. When the connecting seat 87 drives the crossbar 6 to move horizontally, the connecting shaft 810 slides along the horizontal section of the guide groove 89. When the connecting shaft 810 moves to the inclined section of the guide groove 89, the crossbar 6 is vertically displaced relative to the connecting seat 87 under the guidance of the connecting shaft 810.

[0035] The horizontal and inclined sections transition smoothly to prevent the connecting shaft 810 from getting stuck. A reinforcing rod 811 is provided on the side of the crossbar 6. The crossbar 6 and the reinforcing rod 811 are fixedly connected by the connecting plate 812. The distance between the crossbar 6 and the reinforcing rod 811 is greater than the diameter of the ejector pin 4. The connecting plate 812 is slidably connected to the outer wall of the connecting seat 87 by a vertical slide rail. The reinforcing rod 811 and the crossbar 6 are slidably connected to the inner wall of the connecting seat 87 by a vertical slide rail. This allows the reinforcing rod 811 and the crossbar 6 to move with the connecting seat 87 when the connecting seat 87 moves in the horizontal direction, and the connecting seat 87 does not affect the vertical sliding of the reinforcing rod 811 and the crossbar 6.

[0036] The moving template 1 is equipped with a delay mechanism 9.

[0037] The delay mechanism 9 includes a long rod 91 fixed to the outer wall of the moving template 1. A vertical strip groove 92 runs through the long rod 91. A moving block 93 is slidably connected in the strip groove 92. A bracket 94 is fixed to one end of the moving block 93 that extends out of the long rod 91. The end of the bracket 94 away from the slider is fixed to the active rack 81.

[0038] By setting up the long rod 91 and the moving block 93, a predetermined stroke relative displacement is generated between the moving template 1 and the active rack 81, which drives the active rack 81 to move synchronously. In this application, when the ejector pin 4 lifts the car refueling base product 3, the long rod 91 starts to drive the moving block 93 to move synchronously, so as to avoid the crossbar 6 affecting the ejector pin 4 and the car refueling base product 3. By setting up the bracket 94, in the initial state, the ends of the active gear 83 and the crossbar 6 are located outside the fixed template 2 and the moving template 1, so as not to affect its mold closing and opening.

[0039] A method for molding a car fuel filler base includes the following steps: Step S1 Mold Closure Injection: Drive the moving mold plate 1 and the fixed mold plate 2 to close the mold, so that the cavity plate and the core plate 21 together form a molding cavity, and inject molten plastic into it to form the car refueling base product 3; Step S2: Mold opening and ejection of car fuel base product 3: Drive the moving template 1 to separate from the fixed template 2 to open the mold, and then drive several ejector pins 4 to move upward, so that the car fuel base product 3 separates from the core plate 21. Step S3: Adjusting the posture of the car refueling base product 3: Insert the crossbar 6 into the slot 41 of the locking mounting part 32 corresponding to the pin 4 and move it upward, so that the car refueling base product 3 rotates around its hinge mounting part 31 area and presents a tilted posture. Step S4: Remove the tilted car refueling base product 3.

[0040] When in use, after the car refueling base product 3 is formed, the driving moving template 1 is separated from the fixed template 2 to open the mold. During the mold opening process, the moving template 1, in conjunction with the inclined guide post, moves several slides on the fixed template 2 to expose the car refueling base product 3. Then, several ejector pins 4 are driven to move upward to separate the car refueling base product 3 from the core plate 21. At the same time, when the moving template 1 moves upward, it will drive the long rod 91 fixed to the moving template 1 to move upward. When the car refueling base product 3 is separated from the core plate 21, the long rod 91 moves to the point where the moving block 93 abuts against the bottom of the strip groove 92. The moving template 1 continues to move upward, driving the bracket 94 and the active rack 81 to move upward. The upward movement of the drive rack 81 will cause the drive gear 83 meshing with it to rotate. The rotation of the drive gear 83 will cause the transmission shaft 82 and the follower gear 84, which are fixed coaxially with the drive gear 83, to rotate. The rotation of the follower gear 84 will cause the driven gear 85 meshing with it to rotate. The rotation of the driven gear 85 will cause the driven rack 86 meshing with it to move. The driven rack 86 is guided and limited by the slide rail. The movement of the driven rack 86 will cause the connecting seat 87 fixed with the driven rack 86 and the crossbar 6 and reinforcing rod 811 on the connecting seat 87 to move. The end of the crossbar 6 is inserted into a slot 41 located on the outer wall of the corresponding ejector pin 4 in the latch mounting part 32, and the end of the crossbar 6 is located between the car refueling base product 3 and the core plate 21. When the connecting shaft 810 moves within the horizontal section of the guide groove 89, the crossbar 6 only moves horizontally. When the connecting shaft 810 moves to the inclined section, the crossbar 6 and the reinforcing rod 811 slide and connect to the connecting seat 87 via the slide rail. The crossbar 6 and the reinforcing rod 811 move upward, and the crossbar 6 enters the gap 43. The vertical pressure block 42 presses down on the L-shaped pressure rod 74. The rotation of the L-shaped pressure rod 74 will cause the first sleeve 72, which is fixed to the L-shaped pressure rod 74, to rotate. The rotation of the first sleeve 72 will cause the first rocker arm 75, which is fixed to the first sleeve 72, to rotate. The rotation of the first rocker arm 75 will cause the hinged connection to the first rocker arm 75 to rotate. The second rocker arm 710 rotates, which drives the short shaft 713 connected to it to move. The movement of the short shaft 713 drives the limiting inner tube 79 to move inside the outer tube 78, and the spring is stretched. The movement of the limiting inner tube 79 also drives the other short shaft 713 to move, which in turn drives the fourth rocker arm 711 connected to it to rotate. The rotation of the fourth rocker arm 711 drives the third rocker arm 77 to rotate. The rotation of the third rocker arm 77 drives the second sleeve 73 fixed to the third rocker arm 77 to rotate. The rotation of the second sleeve 73 drives the L-shaped top rod 76 fixed to the second sleeve 73 to rotate. The long side of the L-shaped push rod 76 rotates to lift the locking mounting part 32 of the car refueling base product 3, causing the car refueling base product 3 to rotate around its hinge mounting part 31 area, thus presenting an inclined state. The car refueling base product 3, which is now in an inclined state, is picked up and removed by a robotic arm. When it is needed for reuse, the moving template 1 moves down and the end of the crossbar 6 returns to its initial position, located outside the fixed template 2.

[0041] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
