Description

Technical Field

[0001] The utility model relates to the field of injection molding, in particular to a production device for a plastic upper cover of a washing machine. Background Art

[0002] From ancient times to the present, washing clothes has been a household chore that is difficult to avoid. As a result, every household is now inseparable from a washing machine, and the washing machine cover is also an indispensable component. There are mostly two types of washing machine covers: high-performance plastic and metal materials. Generally, the plastic cover of a washing machine is ABS plastic. ABS engineering plastics are generally opaque, light ivory in appearance, non-toxic and odorless. The characteristics of the metal material of the washing machine are high hardness, not easy to deform, but easy to rust. Compared with plastic, it has a larger weight under the same volume. In case of serious leakage, the plastic cover has a higher safety system than the metal one.

[0003] At present, most of the devices for producing plastic covers of washing machines are produced by injection molding machines. During production, a closed space is formed by fitting a movable mold and a static mold. The molten plastic is injected into the gap between the movable mold and the static mold through a transmission pipe. After the injection molding is completed, the movable mold and the static mold are separated to shape the molten plastic, so that the plastic cover of the washing machine is produced and formed.

[0004] However, the above-mentioned washing machine plastic cover production device still has certain shortcomings. When producing finished products, the finished products will be taken out from the injection molding site along with the movable mold. When the movable mold stops moving, they are taken by hand or by a robotic arm. The cost of the robotic arm is high, so most of the time, it is taken by hand. The injection molding machine mold will heat up during injection molding. When the human hand takes it, there is a certain probability of being scalded by accidentally touching the mold, which causes certain safety problems for workers at work. Therefore, it is urgently needed to make improvements on the basis of the washing machine plastic cover production device. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a washing machine plastic cover production device to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a washing machine plastic cover production device, comprising a production device main body, a movable mold and a static mold are installed in the production device main body, a fixed plate is installed at the end of the movable mold, and a protrusion is fixedly installed on the outer wall of the fixed plate, and an air cushion is installed under the movable mold, a placement plate is fixedly installed at the end of the air cushion, and two symmetrical rotating rods are rotatably installed on one side of the end of the placement plate, and a base is fixedly installed at the end of the rotating rod, and a support rod in contact with the placement plate is fixedly installed on the outer wall of the base.

[0007] By adopting the above technical solution, through the action of the convex block, when the movable mold moves, the placement plate drives the air cushion to gradually tilt around the end of the rotating rod, so that the finished product can be successfully obtained through the tilting of the placement plate, reducing the probability of people touching the mold and getting burned when taking the finished product by hand, increasing the safety factor of workers at work, and making the washing machine plastic cover production device more convenient to use.

[0008] The utility model is further configured that the protrusion is designed as a triangle, and the protrusion angles are respectively "130°", "25°" and "25°", and the top edge of the protrusion is designed as a rounded corner.

[0009] By adopting the above technical solution, when the protrusion moves, the protrusion can be easily moved to the bottom end of the placement plate due to the characteristics of the triangle, so that the placement plate is gradually tilted.

[0010] The utility model is further configured such that the support rod is closer to the center of the placement plate than the protrusion.

[0011] By adopting the above technical solution, the support rod supports the placement plate without affecting the movement of the protrusion, so that the placement plate is not prone to fall to one side.

[0012] The utility model is further configured that the edges of the end portions of the placement plate are all rounded.

[0013] By adopting the above technical solution, the protrusion can enter the bottom end of the placement plate more smoothly through the rounded corner design when moving, thereby performing work on the placement plate.

[0014] The utility model is further configured that the air cushion is designed to be in an unfilled state.

[0015] By adopting the above technical solution, the unfilled air cushion has a certain buffering effect, so that when the product falls on the air cushion, the air cushion will catch the product. Since the unfilled air cushion is less elastic, the product will not bounce away, so the product can be protected more safely and the occurrence of product breakage can be reduced.

[0016] The utility model is further configured as follows: an anti-sticking device is slidably installed on the outer wall of the static mold, and the anti-sticking device is composed of a push rod, a push rod, a spring, a limit block and a connecting rod; a connecting rod is installed on the outer wall of the static mold, and a push rod is fixedly installed on the end of the outer wall of the connecting rod, and a push rod for pushing the product is fixedly installed on the middle section of the connecting rod; a spring is slidably connected to the outer wall of the push rod, and a limit block connected to the spring is fixedly installed on the outer wall of the push rod, and a sliding groove for the sliding of the limit block and the spring is opened in the static mold, and the spring is installed on the limit block and the inner wall of the sliding groove.

[0017] By adopting the above technical solution, after the injection molding of the main body of the production device is completed, the product will leave the inner wall of the static mold along with the movable mold, but there is still a certain probability that the product will stick to the static mold, thereby affecting the next injection molding of the main body of the production device. Under the action of the anti-sticking device, when the movable mold leaves the static mold, the product is pushed out synchronously, so that the product moves consistently with the movable mold.

[0018] The utility model is further configured that the push rods are two push rods symmetrically installed at the ends of the connecting rod.

[0019] By adopting the above technical solution, when the top rod slides backward, the force applied to the connecting rod is balanced through the effect of quantity, so that the anti-sticking device has a certain stability.

[0020] The utility model is further configured such that the length of the push rod is on the same horizontal line as the surface of the static mold.

[0021] By adopting the above technical solution, when the movable mold pushes the ejector pin, the push rod slides backward synchronously, so that when the movable mold and the static mold are fitted, the push rod slides into the static mold without affecting the product molding, and when the movable mold moves, the push rod just pushes the product out of the static mold.

[0022] In summary, the utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a convex block, an air cushion, a placing plate and a rotating rod. Through the action of the convex block, when the movable mold moves, the placing plate drives the air cushion to gradually tilt around the end of the rotating rod as the center, so that the finished product can be successfully obtained through the tilting of the placing plate, reducing the probability of people touching the mold when taking the finished product and getting burned, increasing the safety factor of workers at work, and making the washing machine plastic cover production device more convenient to use.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1

[0036] A washing machine plastic cover production device, such as Figure 1 - Figure 6 As shown, the production device comprises a main body 1 in which a movable mold 101 and a static mold 102 are installed.

[0037] Specifically, a fixed plate 2 is installed at the end of the movable mold 101. When the movable mold 101 moves, it drives the fixed plate 2 to move synchronously so that the fixed plate 2 obtains the moving force, and a convex block 3 is fixedly installed on the outer wall of the fixed plate 2. When the fixed plate 2 and the movable mold 101 move synchronously, the fixed plate 2 will drive the convex block 3 to move synchronously, so that the convex block 3 obtains the moving force, and an air cushion 4 is installed under the movable mold 101. When the production device main body 1 injects the product, the product will be reset along with the movable mold 101. During the resetting process, the product will be pushed away from the movable mold 101 by the ejector pin and fall onto the air cushion 4. Under the action of the air cushion 4, the force of the product falling is buffered, thereby reducing the occurrence of product breakage. A placing plate 5 is fixedly installed at the end of the air cushion 4. The placing plate 5 has a lifting effect on the air cushion 4, so that when the product falls on the air cushion 4, the air cushion 4 can support the product, and the placing plate 5 can lift the product. Two symmetrical rotating rods 6 are rotatably installed on one side of the end of the placement plate 5. When the protrusion 3 works on the placement plate 5, one side of the placement plate 5 will rise. Under the action of the rotating rod 6, the placement plate 5 is rotated around the rotating rod 6, thereby realizing the inclination of the placement plate 5, and a base 7 is fixedly installed on the end of the rotating rod 6. Through the setting of the base 7, the rotating rod 6 has stability, so that the placement plate 5 can be tilted smoothly. A supporting rod 8 connected to the placement plate 5 is fixedly installed on the outer wall of the base 7. When the protrusion 3 passes under the placement plate 5, one side of the placement plate 5 is gradually raised, and when the protrusion 3 continues to move forward, it gradually loses contact with the placement plate 5, so that the bottom end of the placement plate 5 loses support and falls to one side. Through the action of the supporting rod 8, when the protrusion 3 is not in contact with the placement plate 5, the supporting rod 8 will contact with the placement plate 5, so that the placement plate 5 can be stable.

[0038] See also Figure 1 - Figure 6 The protrusion 3 is designed as a triangle. When the protrusion 3 moves, the characteristics of the triangle make the protrusion 3 easily move to the bottom of the placement plate 5, so that the placement plate 5 gradually tilts, and the angles of the protrusion 3 are "130°", "25°" and "25°" respectively. Under the action of the angle, the protrusion 3 can better work on the placement plate 5, so that the placement plate 5 tilts, allowing the product to slide smoothly, and the top edge of the protrusion 3 is designed with a rounded corner. Through the setting of the rounded corner, when the top of the protrusion 3 contacts the placement plate 5, it can move more smoothly, so that the production device has a certain stability.

[0039] See also Figure 1 - Figure 6 Compared with the protrusion 3, the support rod 8 is closer to the center of the placement plate 5. While not affecting the movement of the protrusion 3, the support rod 8 supports the placement plate 5, so that the placement plate 5 is not prone to fall to one side.

[0040] See also Figure 1 - Figure 6 The edges of the end of the placement plate 5 are all rounded, so that when the protrusion 3 moves, it can enter the bottom end of the placement plate 5 more smoothly through the rounded design, thereby performing work on the placement plate 5.

[0041] See also Figure 1 - Figure 6 The air cushion 4 is designed to be in an unfilled state. The unfilled air cushion 4 has a certain buffering effect, so when the product falls on the air cushion 4, the air cushion 4 will catch the product. Since the unfilled air cushion 4 is less elastic, the product will not bounce away, so the product can be protected more safely and the occurrence of product rupture can be reduced.

[0042] Embodiment 2

[0043] See also Figure 7 - Figure 8The difference between the second embodiment and the first embodiment is that on the basis of retaining the first embodiment, an anti-sticking device 9 is slidably installed on the outer wall of the static mold 102. After the injection molding of the production device body 1 is completed, the product will leave the inner wall of the static mold 102 along with the movable mold 101, but there is still a certain probability that the product will be attached to the static mold 102, thereby affecting the next injection molding of the production device body 1. Under the action of the anti-sticking device 9, when the movable mold 101 leaves the static mold 102, the product is pushed out synchronously, so that the product is consistent with the movable mold 101. The anti-sticking device 9 is composed of a push rod 10, a push rod 11, a spring 12, a limit block 13 and a connecting rod 14. The connecting rod 14 is installed on the outer wall of the static mold 102, and the push rod 10 is fixedly installed on the end of the outer wall of the connecting rod 14. In the process of the dynamic mold 101 and the static mold 102 being fitted together, the dynamic mold 101 will gradually squeeze the push rod 10, so that the push rod 10 obtains a sliding force, and a push rod 11 for pushing the product is fixedly installed in the middle section of the connecting rod 14. When the push rod 10 is squeezed by the dynamic mold 101, it moves to the The static mold 102 slides inside, thereby pushing the connecting rod 14. When the connecting rod 14 moves backward, it synchronously drives the push rod 11 to move backward, so that the push rod 11 obtains the sliding force. The outer wall of the push rod 10 is slidably connected with the spring 12, and the outer wall of the push rod 10 is fixedly installed with a limit block 13 connected with the spring 12. When the push rod 10 slides backward, it synchronously drives the limit block 13 to slide, thereby squeezing the spring 12, so that when the spring 12 loses its limit, it will push the limit block 13 to reset, and A sliding groove 15 for sliding of the limit block 13 and the spring 12 is provided in the static mold 102. The spring 12 is installed on the limit block 13 and the inner wall of the sliding groove 15. When the limit block 13 squeezes the spring 12, since the spring 12 is connected to the inner wall of the sliding groove 15, the spring 12 will push the limit block 13 to reset when it loses its restriction, so that the ejector rod 10 drives the connecting rod 14 to reset, thereby causing the push rod 11 to reset synchronously, so that the push rod 11 gradually pushes the product out when the movable mold 101 moves.

[0044] See also Figure 7 - Figure 8 The top rods 10 are two symmetrically mounted at the ends of the connecting rod 14. When the top rods 10 slide backward, the force on the connecting rod 14 is balanced through the effect of quantity, so that the anti-sticking device 9 has a certain stability.

[0045] See also Figure 7 - Figure 8 The length of the push rod 11 is on the same horizontal line as the surface of the static mold 102. When the dynamic mold 101 pushes the push rod 10, the push rod 11 slides backward synchronously, so that when the dynamic mold 101 and the static mold 102 are fitted together, the push rod 11 slides into the static mold 102 without affecting the product molding. When the dynamic mold 101 moves, the push rod 11 just pushes the product out of the static mold 102.

[0046] The working principle of the utility model is as follows: after the production device main body 1 injection molds the plastic upper cover of the washing machine, the movable mold 101 retreats backwards, so that the ejector pin pushes the finished product out of the mold, thereby causing the finished product to fall downward onto the air cushion 4 below. Since the air cushion 4 is in an unfilled state, when the finished product falls on the air cushion 4, it can have a certain buffering effect on the finished product. When the production device main body 1 performs injection molding again, the movable mold 101 drives the fixed plate 2 and the protrusion 3 to move synchronously. When the highest point of the protrusion 3 moves to the bottom of the placement plate 5, the placement plate 5 and the air cushion 4 rotate around the end of the rotating rod 6, thereby causing the air cushion 4 to gradually tilt. When the protrusion 3 does not contact the placement plate 5, the placement plate 5 is supported by the support rod 8, thereby preventing the placement plate 5 from falling to one side. This device allows the finished product to be taken out of the production device main body 1 without manual removal after being ejected by the ejector pin, thereby reducing the safety risks of being scalded by the high temperature of the mold or being squeezed by the machine when taking it by hand.

[0047] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
