Description

Technical Field

[0001] This utility model relates to the field of plastic parts processing mold technology, and in particular to a mold for processing plastic parts for electrical appliances. Background Technology

[0002] Electrical appliance plastic parts processing refers to processing plastic materials into parts suitable for electrical appliances through various processing techniques. These parts are usually used for the outer casing, internal structure, insulation components, etc. of electrical appliances. Injection molding is one of the most commonly used plastic processing methods. Molten plastic is injected into a mold and cooled to form a solid shape. It is suitable for mass production and can manufacture parts with complex shapes.

[0003] However, some existing molds for processing plastic parts for electrical appliances have problems in actual use. The heated plastic tends to stick to the inside of the mold, making it inconvenient to unload the material. In addition, the molded plastic parts need to be cooled down during use to better set their shape. However, some existing methods of cooling by nature result in low processing efficiency. Therefore, it is necessary to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a mold for processing plastic parts for electrical appliances.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mold for processing plastic parts for electrical appliances includes a first mold, with fixed rods horizontally fixedly connected to the four corners of the first mold surface. A second mold is horizontally slidably connected to the first mold, with the four fixed rods slidably sleeved at the four corners of the second mold surface. Sliding sleeves are fixedly connected to the four corners of the second mold surface, and the four sliding sleeves slidably sleeved on the surfaces of the four fixed rods. A cooling mechanism is provided on the surface of the second mold. Multiple top blocks are slidably connected to the grooves on the surface of the second mold. A sliding mechanism for sliding the multiple top blocks is provided on the surface of the second mold. The multiple top blocks facilitate the ejection of the formed plastic parts after molding, making the device easier to demold and thus improving the effectiveness of the device.

[0007] Preferably, the cooling mechanism includes a heat dissipation plate, which is fixedly connected to the surface of the second mold on the side away from the first mold. A water inlet and a water outlet are fixedly connected to symmetrical sides of the surface of the heat dissipation plate, and a water tank is provided inside the heat dissipation plate. The water inlet and the water outlet are respectively located at both ends of the water tank for water circulation inside the heat dissipation plate, which also facilitates cooling of the surface of the second mold.

[0008] Furthermore, the sliding mechanism includes sliding rods. Multiple mating grooves are formed in the grooves on the surface of the second mold. Multiple top blocks are slidably connected to the interiors of these grooves. Each of the multiple mating grooves has a first sliding groove extending through it. The surface of the heat sink has multiple second sliding grooves extending through it, each corresponding to a first sliding groove. Multiple sliding rods are provided, slidably connected to each of the first and second sliding grooves. The multiple second sliding grooves are offset from the water tank. A fixing plate is slidably connected to the side of the heat sink away from the second mold. The fixing plate is fixedly connected to one end of each of the sliding rods. Springs are fitted onto the surfaces of each of the sliding rods. The two ends of each spring are respectively positioned on opposite sides of the heat sink and the fixing plate, used to restrict the sliding of the top blocks and sliding rods, thereby facilitating the ejection of plastic parts from the grooves on the surface of the second mold.

[0009] Preferably, the four fixing rods are paired up, and a first connecting plate is fixedly connected between each pair of fixing rods. The two first connecting plates are both vertically arranged, and the same second connecting plate is horizontally fixedly connected between the two first connecting plates. The second connecting plate is disposed on the surface of the fixing plate and is used to allow the second connecting plate and the first mold to slide simultaneously, thereby facilitating the simultaneous sliding of the fixing plate and multiple top blocks.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, the first mold can be slid towards the end closer to the second mold to allow the first mold and the second mold to engage. At the same time, the water inlet and outlet pipes on the surface of the heat sink, and the water circulation system set up externally, circulate water in the water tank inside the heat sink. With the cooling of the circulating water, the molded plastic parts can be cooled during use, allowing the parts to set faster.

[0012] 2. During use, the first mold is slid to separate the first mold and the second mold. As the first mold slides away from the second mold, it will drive the four fixed rods to slide. With the connection of the two first connecting plates and the second connecting plate, the fixed plate will slide. The plastic parts inside the second mold can be pushed out through the four sliding rods and the top block, thereby improving the ease of use of the device. Attached Figure Description

[0020] Reference Figures 1-5 A mold for processing plastic parts for electrical appliances includes a first mold 1. Fixed rods 11 are horizontally fixedly connected to the four corners of the surface of the first mold 1. A second mold 2 is horizontally slidably connected to the first mold 1. The four fixed rods 11 are slidably sleeved at the four corners of the surface of the second mold 2. Sliding sleeves 24 are fixedly connected to the four corners of the surface of the second mold 2 and slidably sleeved on the surfaces of the four fixed rods 11. A cooling mechanism is provided on the surface of the second mold 2. Multiple top blocks 42 are slidably connected to the grooves on the surface of the second mold 2. A sliding mechanism for sliding the multiple top blocks 42 is provided on the surface of the second mold 2. The multiple top blocks 42 facilitate the ejection of the formed plastic parts after molding, making the device easier to demold and thus improving the effectiveness of the device.

[0021] In this utility model, the cooling mechanism includes a heat dissipation plate 3, which is fixedly connected to the surface of the second mold 2 on the side away from the first mold 1. A water inlet 31 and a water outlet 32 ​​are fixedly connected to the two symmetrical sides of the surface of the heat dissipation plate 3, and a water tank 33 is provided inside the heat dissipation plate 3. The water inlet 31 and the water outlet 32 ​​are respectively located at both ends of the water tank 33 for water circulation inside the heat dissipation plate 3, and also for cooling the surface of the second mold 2.

[0022] In this utility model, the sliding mechanism includes a slide rod 41. Multiple mating grooves 22 are formed in the groove on the surface of the second mold 2. Multiple top blocks 42 are slidably connected to the interior of the multiple mating grooves 22. A first sliding groove 23 is formed through the interior of each of the multiple mating grooves 22. Multiple second sliding grooves 34 are formed through the surface of the heat sink 3, each corresponding to a first sliding groove 23. Multiple slide rods 41 are provided, slidably connected to the interior of each first sliding groove 23 and second sliding groove 34. The multiple second sliding grooves 34 are all offset from the water tank 33. A fixing plate 4 is slidably connected to the side of the heat sink 3 away from the second mold 2. The fixing plate 4 is fixedly connected to one end of each slide rod 41. Springs 43 are sleeved on the surface of each slide rod 41. The two ends of each spring 43 are respectively located on opposite sides of the heat sink 3 and the fixing plate 4, used to restrict the sliding of the multiple top blocks 42 and slide rods 41, thereby facilitating the ejection of plastic parts from the groove on the surface of the second mold 2.

[0023] In this utility model, the four fixing rods 11 are paired up, and a first connecting plate 12 is fixedly connected between each pair of fixing rods 11. The two first connecting plates 12 are both vertically arranged, and the same second connecting plate 13 is horizontally fixedly connected between the two first connecting plates 12. The second connecting plate 13 is disposed on the surface of the fixing plate 4 and is used to enable the second connecting plate 13 and the first mold 1 to slide simultaneously, thereby facilitating the simultaneous sliding of the fixing plate 4 and multiple top blocks 42.

[0024] Working principle: In actual use, the multiple top blocks 42 facilitate the ejection of the molded plastic parts after they have been formed, making the device easier to demold and improving its performance. During use, the first mold 1 can be slid towards the second mold 2, allowing them to engage. Simultaneously, water pipes at the inlet 31 and outlet 32 ​​on the surface of the heat sink 3, along with an external water circulation system, circulate water through the internal water tank 33 of the heat sink 3. This cooling of the circulating water helps to cool the molded plastic parts, allowing them to solidify more quickly. After this, the first mold 1 is slid away from the second mold 2, causing the four fixing rods 11 to slide. The connection between the two first connecting plates 12 and the second connecting plate 13 causes the fixing plate 4 to slide. The four sliding rods 41 and the top blocks 42 then push out the plastic parts inside the second mold 2, further improving the device's ease of use.
