Technical Field
[0001] This utility model relates to the technical field of children's toy injection molding equipment, and in particular to a children's toy injection molding equipment that is easy to load. Background Technology
[0002] In the children's toy manufacturing industry, injection molding equipment is the core equipment for molding plastic raw materials into toy products. Existing children's toys typically use different feed ports, which are easily replaceable using threaded connections. The proper operation of the injection molding machine is crucial for ensuring the production quality and efficiency of children's toys. During continuous operation, the internal temperature of the injection molding machine rises steadily. Excessive temperature can interfere with the normal plasticizing and injection molding process, leading to problems such as poor dimensional accuracy and surface quality deterioration (e.g., scorch marks) in the molded parts of children's toys, ultimately resulting in a lower product yield.
[0003] The inventors believe that the following defects often exist: when the injection molding machine body is working continuously, the temperature inside the injection molding machine body continues to rise. Excessive temperature will interfere with the normal plasticization and injection process of plastic, resulting in problems such as poor dimensional accuracy and surface quality deterioration (such as scorch marks) in children's toy injection molded parts, thus reducing the product yield. Therefore, in order to solve the above problems, a children's toy injection molding equipment with convenient material feeding is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where the temperature inside the injection molding machine continuously rises during continuous operation, and to propose a convenient material loading injection molding device for children's toys.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a children's toy injection molding equipment for convenient material feeding, comprising an injection molding machine body, an inlet installed on the surface of the injection molding machine body, heat dissipation devices provided on both sides of the injection molding machine body, the two heat dissipation devices comprising two U-shaped frames, the two U-shaped frames being fixedly connected to the two sides of the injection molding machine body respectively, two L-shaped plates being fixedly connected to one side of the U-shaped frame, bolts being inserted into the internal threads of the L-shaped plates, two fixing rods being fixedly connected to one side of the U-shaped frame, a rotating plate being rotatably connected to the arc surface of the fixing rods, a circular hole being opened on the surface of the rotating plate, and the surface of the L-shaped plate being slidably connected to the U-shaped frame.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up a heat dissipation device, the internal temperature of the injection molding machine body is reduced, which prevents the temperature inside the injection molding machine body from rising continuously during continuous operation. Excessive temperature will interfere with the normal plasticization and injection process of plastic, resulting in problems such as poor dimensional accuracy and surface quality deterioration (such as scorch marks) in children's toy injection molded parts, thus reducing the product yield and improving the practicality of the device.
[0007] Preferably, the arc surface of the fixing rod is fitted with a torsion spring, and the two ends of the torsion spring are fixedly connected to the U-shaped frame and the fixing rod, respectively.
[0008] The aforementioned components achieve the following effect: they automatically open the rotating plate and keep it in the open position, facilitating further operations by staff.
[0009] Preferably, a square rod is fixedly connected to the arc surface of the bolt, and the surface of the square rod is in contact with the L-shaped plate.
[0010] The aforementioned components achieve the following effect: preventing bolts from being pulled out, thus avoiding the situation where the bolt's arc surface separates from the L-shaped plate when the operator rotates the bolt, which would otherwise require secondary installation and increase the operator's workload.
[0011] Preferably, the surface of the U-shaped frame is fixedly connected to two auxiliary blocks, and the arc surface of the bolt is adapted to the size of the circular hole of the rotating plate.
[0012] The aforementioned components achieve the following effects: they calibrate the position of the filter screen, and the automatic positioning and calibration during the filter screen installation process enables the filter screen to quickly and accurately reach the preset installation position, reducing the time and error of manual adjustment.
[0013] Preferably, the arc surface of the feed inlet is provided with a protective device, the protective device including a shaped frame, the shaped frame being fixedly connected to the arc surface of the feed inlet, a rotating rod being fixedly connected inside the shaped frame, a protective plate being rotatably connected to the arc surface of the rotating rod, a single-hole plate being fixedly connected to the arc surface of the protective plate, a fixed plate being fixedly connected to the arc surface of the feed inlet, and a plug rod being slidably inserted inside the fixed plate.
[0014] The effect achieved by the above-mentioned components is as follows: by setting up a protective device, the feed port is protected, and it is avoided that if the injection molding machine body is not used for a long time, impurities will mix into the plastic raw materials, which will cause appearance defects and mechanical property degradation (such as reduced strength) in the injection molded parts of the toys, thus shortening the service life of the toys and improving the reliability of the device.
[0015] Preferably, a spring is fitted onto the arc surface of the insertion rod, and the two ends of the spring are fixedly connected to the fixing plate and the insertion rod, respectively.
[0016] The above-mentioned components achieve the following effects: they improve the stability of the insertion rod, and the stable rebound force of the spring can quickly push the insertion rod into the single-hole plate to form a firm locking position, preventing the protective plate from accidentally rotating and opening, and effectively blocking external debris from entering the feed port.
[0017] Preferably, a sealing gasket is fixedly connected to the surface of the protective plate, and the size of the sealing gasket is adapted to the size of the protective plate.
[0018] The aforementioned components achieve the following effect: they seal the feed inlet, effectively preventing external dust, moisture, and other contaminants from entering the injection molding machine body and polluting the raw materials, thus avoiding defects in children's toy injection molded parts due to raw material contamination.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting up a heat dissipation device, the internal temperature of the injection molding machine body is reduced, which avoids the continuous rise in temperature inside the injection molding machine body when it is working continuously. Excessive temperature will interfere with the normal plasticization and injection process of plastic, resulting in problems such as poor dimensional accuracy and surface quality deterioration (such as scorch marks) in children's toy injection molded parts, thus reducing the product yield and improving the practicality of the device.
[0021] 2. In this utility model, by setting a protective device, the inlet is protected, which avoids the situation where impurities mix into the plastic raw material and cause appearance defects and decreased mechanical properties (such as reduced strength) in the toy injection molded parts due to the injection molding machine body not being used for a long time, thus shortening the service life of the toy and improving the reliability of the device.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a convenient injection molding equipment for children's toys, including an injection molding machine body 1. A feed inlet 2 is installed on the surface of the injection molding machine body 1. Heat dissipation devices 3 are provided on both sides of the injection molding machine body 1. By setting the heat dissipation devices 3, the internal temperature of the injection molding machine body 1 is reduced, preventing the temperature inside the injection molding machine body 1 from continuously rising during continuous operation. Excessive temperature can interfere with the normal plasticizing and injection molding process of the plastic, leading to problems such as poor dimensional accuracy and surface quality deterioration (e.g., scorch marks) in the injection molded parts of children's toys, resulting in a lower product yield. This improves the practicality of the device. A protective device 4 is provided on the arc surface of the feed inlet 2. By setting the protective device 4, the feed inlet 2 is protected, preventing impurities from mixing into the plastic raw materials if the injection molding machine body 1 is not used for a long time, which can cause appearance defects and decreased mechanical properties (e.g., reduced strength) in the injection molded parts of the toys, shortening the service life of the toys. This improves the reliability of the device.
[0030] The specific setup and function of its heat dissipation device 3 and protection device 4 will be explained below.
[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the two heat dissipation devices 3 include two U-shaped frames 31, which are fixedly connected to both sides of the injection molding machine body 1 respectively. Two L-shaped plates 35 are fixedly connected to one side of the U-shaped frame 31, and bolts 36 are threaded into the L-shaped plates 35. Two fixing rods 33 are fixedly connected to one side of the U-shaped frame 31. A rotating plate 34 is rotatably connected to the arc surface of the fixing rod 33. A circular hole is opened on the surface of the rotating plate 34. The surface of the L-shaped plate 35 is slidably connected to the U-shaped frame 31. A torsion spring 38 is sleeved on the arc surface of the fixing rod 33. The two ends of the torsion spring 38 are fixedly connected to the U-shaped frame 31 and the fixing rod 33 respectively. When the operator needs to... To disassemble the filter screen 32, the operator first rotates the bolt 36 within the L-shaped plate 35 until the arc surface of the bolt 36 separates from the circular hole of the rotating plate 34. Then, the torque of the torsion spring 38 drives the rotating plate 34 to rotate on the arc surface of the fixed rod 33 until the rotating plate 34 no longer affects the movement of the L-shaped plate 35. The operator can then pull the filter screen 32 to slide within the U-shaped frame 31 until the filter screen 32 separates. This achieves the effect of automatically opening the rotating plate 34 while keeping it in the open position for easy further operation. A square rod 37 is fixedly connected to the arc surface of the bolt 36. The surface of the U-shaped frame 37 is in contact with the L-shaped plate 35. When the operator needs to remove the filter screen 32, the operator first rotates the bolt 36 to drive the square rod 37 until the surface of the square rod 37 is in contact with the L-shaped plate 35. At this time, the arc surface of the bolt 36 is completely separated from the round hole of the rotating plate 34, thus preventing the bolt 36 from being pulled out. This avoids the situation where the arc surface of the bolt 36 separates from the L-shaped plate 35 when the operator rotates the bolt 36, which would require secondary installation and increase the operator's workload. Two auxiliary blocks 39 are fixedly connected to the surface of the U-shaped frame 31, and the bolt 36... The arc surface matches the size of the circular hole in the rotating plate 34. When the operator needs to install the filter screen 32, the operator first places the filter screen 32 in the U-shaped frame 31 and slides it until the surface of the filter screen 32 is in contact with the surface of the auxiliary block 39. At this time, the operator can continue to push the filter screen 32 to move, and the filter screen 32 slides on the surface of the auxiliary block 39 until the surface of the filter screen 32 is in contact with the U-shaped frame 31. This achieves the effect of calibrating the position of the filter screen 32. The automatic positioning and calibration during the installation process of the filter screen 32 enables the filter screen 32 to quickly and accurately reach the preset installation position, reducing the time and error of manual adjustment.
[0032] Reference Figure 4 , Figure 5 and Figure 6As shown, specifically, the protective device 4 includes a shaped frame 41, which is fixedly connected to the arc surface of the feed inlet 2. A rotating rod 42 is fixedly connected inside the shaped frame 41, and a protective plate 43 is rotatably connected to the arc surface of the rotating rod 42. A single-hole plate 45 is fixedly connected to the arc surface of the protective plate 43. A fixed plate 46 is fixedly connected to the arc surface of the feed inlet 2. A rod 47 is slidably inserted into the fixed plate 46, and a spring 48 is sleeved on the arc surface of the rod 47. The two ends of the spring 48 are respectively connected to the fixed plate 46. 6 and the insertion rod 47 are fixedly connected. When the worker needs to use the protective plate 43, the worker first pulls the insertion rod 47 to slide it inside the fixed plate 46. At this time, the spring 48 is stretched until the arc surface of the insertion rod 47 no longer affects the movement of the single-hole plate 45. Then the worker can rotate the protective plate 43 on the arc surface of the rotating rod 42 until the surface of the single-hole plate 45 is in contact with the fixed plate 46. At this time, the worker can release the insertion rod 47. At this time, the rebound force of the spring 48 drives the insertion rod 47 to move. The rod 47 slides within the fixed plate 46 until it is inserted into the single-hole plate 45. This improves the stability of the rod 47. The stable rebound force of the spring 48 quickly pushes the rod 47 into the single-hole plate 45, forming a secure locking position. This prevents the protective plate 43 from accidentally rotating and opening, effectively blocking external debris from entering the feed port 2. A sealing gasket 44 is fixedly connected to the surface of the protective plate 43. The size of the sealing gasket 44 matches the size of the protective plate 43. When the operator needs to protect the feed port 2, the operator first rotates the protective plate 43, causing the sealing gasket 44 to rotate on the arc surface of the rotating rod 42 until the surface of the sealing gasket 44 is in contact with the surface of the feed port 2. At this time, the operator can push the rod 47 to slide within the fixed plate 46 until it is inserted into the single-hole plate 45. This seals the feed port 2, effectively preventing external dust, moisture, etc. from entering the injection molding machine body 1 and contaminating the raw materials, thus avoiding defects in the injection molded parts of children's toys due to contamination of the raw materials.
[0033] Working principle: When the operator needs to disassemble the filter screen 32, firstly, the operator rotates the bolt 36 to drive the square rod 37 until the surface of the square rod 37 is in contact with the L-shaped plate 35. At this time, the arc surface of the bolt 36 is completely separated from the round hole of the rotating plate 34. Then, the torque of the torsion spring 38 drives the rotating plate 34 to rotate on the arc surface of the fixed rod 33 until the rotating plate 34 no longer affects the movement of the L-shaped plate 35. Then, the operator can pull the filter screen 32 to slide within the U-shaped frame 31 until the filter screen 32 separates. When the operator needs to install the filter screen 32, firstly, the operator places the filter screen 32 to slide within the U-shaped frame 31. The filter screen 32 is pushed until its surface is in contact with the surface of the auxiliary block 39. At this point, the operator can continue to push the filter screen 32 to move. The filter screen 32 slides on the surface of the auxiliary block 39 until its surface is in contact with the U-shaped frame 31. This achieves the effect of reducing the internal temperature of the injection molding machine body 1, preventing the temperature inside the injection molding machine body 1 from rising continuously during continuous operation. Excessive temperature will interfere with the normal plasticization and injection process of plastic, leading to problems such as poor dimensional accuracy and surface quality deterioration (such as scorch marks) in children's toy injection molded parts, resulting in a decrease in product yield and improving the practicality of the device.
[0034] When the operator needs to use the protective plate 43, the operator first pulls the insertion rod 47 to slide within the fixed plate 46. At this time, the spring 48 is stretched until the arc surface of the insertion rod 47 no longer affects the movement of the single-hole plate 45. Then, the operator can rotate the protective plate 43 on the arc surface of the rotating rod 42 until the surface of the sealing gasket 44 is in contact with the surface of the feed port 2. At this time, the operator can release the insertion rod 47. The rebound force of the spring 48 drives the insertion rod 47 to slide within the fixed plate 46 until the insertion rod 47 is inserted into the single-hole plate 45, thus achieving the effect of protecting the feed port 2. This prevents impurities from mixing into the plastic raw materials when the injection molding machine body 1 has not been used for a long time, which would cause appearance defects and decreased mechanical properties (such as reduced strength) in the toy injection molded parts, resulting in a shortened service life of the toy and improving the reliability of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
