Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with a self-adaptive cooling system. Background Art

[0002] Injection molds are tools for producing plastic products and are also tools that give plastic products complete structures and precise dimensions. Injection molding uses heated and melted plastic to be injected into the mold cavity of the injection mold under high pressure by an injection molding machine. After cooling and solidification, the mold is opened and then demolded to obtain a molded product.

[0003] The Chinese patent with announcement number CN217704580U is an injection mold with injection mold cooling, comprising: a base plate, a fixed frame connected to the top of the base plate, and an upper mold and a lower mold located on the inner side of the fixed frame and symmetrically distributed up and down; the top of the fixed frame is connected to a cylinder, the output end of the cylinder is connected to a piston rod, the bottom of the piston rod extends to the inner side of the fixed frame and is connected to the upper mold; a temperature conduction cavity is provided in the inner wall of the lower mold, and the top surface of the base plate is detachably connected to a hot air blower and a cooler, and the hot air blower and the cooler are both connected to the temperature conduction cavity in the lower mold through a connecting pipe; the top of the base plate is connected to a support seat, and the upper ports of the two vertical sections of the support seat are telescopically and slidably connected to a movable plate, and the top of the movable plate is connected to the lower mold.

[0004] In the above scheme, the supercooler generates cold air that enters the temperature conduction cavity, quickly cooling and molding the product in the mold, thereby improving the overall production quality and efficiency. However, it has the following disadvantages: when cooling the product, this mold can only locally cool the bottom surface of the product, which makes the product prone to uneven cooling, which easily leads to deformation of the product, thereby reducing the use effect of the injection mold. Utility Model Content

[0005] The purpose of the utility model is to provide an injection mold with an adaptive cooling system to solve the problem that when the mold cools the product, it can only partially cool the bottom surface of the product, which makes the product prone to uneven cooling and thus easily leads to deformation of the product.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical solutions: an injection mold with an adaptive cooling system includes a lower mold, the lower mold is arranged above a placement plate, an upper mold is arranged above the lower mold, a casting tube is fixed on the top surface of the upper mold, a temperature sensing module is arranged on the top surface of the upper mold, a placement groove is provided on the bottom surface of the upper mold and the top surface of the lower mold, a metal frame is provided on the inner wall of the placement groove, a plurality of connecting columns are fixed on the bottom surface of the metal frame on the lower mold, a receiving groove is provided on the rear side of the lower mold, a cooling module is fixed on the inner wall of the receiving groove, and the cooling module is connected to the upper mold.

[0007] Preferably, limiting grooves are provided at the four corners of the top surface of the lower mold, and limiting columns are fixed at the four corners of the bottom surface of the upper mold. The limiting columns are slidably connected to the limiting grooves. The cooperation between the limiting columns and the limiting grooves can ensure that the upper mold always maintains linear motion when moving, so that the upper mold can accurately perform mold closing work with the lower mold.

[0008] Preferably, the bottom end of the limit column is provided with an arc surface, which can effectively position the limit column when the upper mold and the lower mold are closed, so that when the limit column is slightly offset from its position, the arc surface can guide the limit column, so that the limit column can be accurately aligned with the limit groove.

[0009] Preferably, a mounting bracket is fixed to the top surface of the placement plate, a driving member is fixed to the top surface of the mounting bracket, a support frame is fixed to the top surface of the upper mold, the support frame corresponds to the casting pipe, and the bottom surface of the driving member is fixed to the top surface of the support frame.

[0010] Preferably, sliding blocks are fixed on the left and right sides of the upper mold, and sliding grooves are opened on the left and right sides of the inner wall of the mounting frame. The sliding blocks are slidably connected to the sliding grooves. The cooperation between the sliding blocks and the sliding grooves can increase the stability of the upper mold movement process and prevent the upper mold from shaking during movement, so that the upper mold and the lower mold can accurately complete the mold closing work.

[0011] Preferably, a sealing gasket is fixed to the top surface of the lower mold, and the top surface of the sealing gasket is in contact with the bottom surface of the upper mold. The well-sealed mold body can prevent external impurities (such as dust, air, etc.) from entering the mold cavity, thereby preventing defects (such as bubbles, inclusions, etc.) from forming on the surface of the injection molded product, which helps to improve the appearance quality of the product and the consistency of its internal performance.

[0012] Preferably, a mounting groove is provided on the top surface of the placement plate, a slide rail is fixed to the inner wall of the mounting groove, and the top surface of the slide rail slider is fixed to the bottom surface of the lower mold. The movable lower mold allows staff to more conveniently approach various parts of the interior of the lower mold, thereby facilitating the cleaning, repair, and inspection and maintenance of components such as the cooling system inside the lower mold.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Through the cooperation of the metal frame and the cooling module, the injection molded product can be effectively cooled when the internal temperature of the upper and lower molds is too high, avoiding defects such as warping and deformation of the product due to uneven cooling, thereby improving the quality and dimensional accuracy of the product. At the same time, the conduction column can quickly conduct the heat of the injection molded product. Under the action of the metal frame and the cooling module, an efficient heat exchange system is formed, which can accelerate the cooling speed of the injection molded product, shorten the injection molding cycle, and improve production efficiency.

[0015] Second, the coordination of the limiting posts and limiting grooves increases the stability of the connection between the upper and lower molds, allowing the mold body to better maintain overall structural rigidity when under pressure, reducing the possibility of deformation of the mold body, and helping to ensure the dimensional accuracy and quality stability of the injection molded product. The coordination of the sliding block and the sliding groove guides the upper mold to accurately align with the lower mold. This guiding structure limits the direction of movement of the upper mold during mold closing, avoiding misalignment, thereby ensuring a precise match between the upper and lower mold cavities, and helping to produce injection molded products with high dimensional accuracy and accurate shape.

[0016] Third, the sealing gasket improves the seal between the lower and upper molds. During the injection molding process, if there is a gap between the lower and upper molds, the injection material may leak out, which not only affects the injection molding effect, but may also pollute the injection molding environment and even damage the injection molding equipment. The sealing gasket can fill the tiny gap between the upper and lower molds, forming a sealed injection space, ensuring that the material is effectively molded in the cavity inside the mold body, thereby improving injection molding efficiency. The slide rail reduces the friction between the lower mold and the placement plate, making it easier for workers to remove the molded plastic product from the lower mold. Compared with traditional fixed systems, the movable lower mold provides more operating space and reduces the risk of damage to the product during demolding. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] During use, through the cooperation of the metal frame 5 and the cooling module 8, the injection molded product can be effectively cooled down when the internal temperature of the upper mold 3 and the lower mold 1 is too high, so as to avoid defects such as warping and deformation of the product due to uneven cooling, thereby improving the quality and dimensional accuracy of the product. At the same time, the conduction column 11 can quickly conduct the heat of the injection molded product, thereby forming an efficient heat exchange system under the action of the metal frame 5 and the cooling module 8, which can accelerate the cooling speed of the injection molded product, shorten the injection molding cycle, and improve production efficiency. The temperature of the mold body can be detected by the temperature sensing module. When the temperature of the mold body is too high, the signal can be transmitted to the cooling module 8 through the terminal, thereby ensuring the smooth progress of the cooling work.

[0025] like Figure 1-Figure 4 As shown, limiting grooves 12 are provided at the four corners of the top surface of the lower mold 1, and limiting columns 13 are fixed at the four corners of the bottom surface of the upper mold 3. The limiting columns 13 are slidably connected to the limiting grooves 12, and the bottom ends of the limiting columns 13 are provided with an arc surface.

[0026] During use, the cooperation of the limiting post 13 and the limiting groove 12 can increase the connection stability between the upper mold 3 and the lower mold 1, so that the mold body can better maintain the rigidity of the overall structure when under pressure, reduce the possibility of deformation of the mold body, and help ensure the dimensional accuracy and quality stability of the injection molded product. At the same time, the cooperation of the limiting post 13 and the limiting groove 12 can ensure that the upper mold 3 always maintains linear motion when moving, so that the upper mold 3 can accurately close the mold with the lower mold 1. The arc surface can effectively position the limiting post 13 when the upper mold 3 and the lower mold 1 are closed, so that when the limiting post 13 is slightly offset, the arc surface can guide the limiting post 13, so that the limiting post 13 is accurately aligned with the limiting groove 12.

[0027] like Figure 1-Figure 4 As shown, a mounting bracket 14 is fixed to the top surface of the placement plate 2, a driving member 15 is fixed to the top surface of the mounting bracket 14, a support frame 16 is fixed to the top surface of the upper mold 3, the support frame 16 corresponds to the casting pipe, the bottom surface of the driving member 15 is fixed to the top surface of the support frame 16, sliding blocks 17 are fixed on the left and right sides of the upper mold 3, and sliding grooves 18 are provided on the left and right sides of the inner wall of the mounting bracket 14, and the sliding blocks 17 are slidably connected to the sliding grooves 18.

At the same time, the cooperation of the sliding block 17 and the sliding groove 18 can increase the stability of the upper mold 3 during movement, prevent the upper mold 3 from shaking during movement, so that the upper mold 3 and the lower mold 1 can accurately complete the mold closing work.

[0029] like Figure 1-Figure 4 As shown, a sealing gasket 19 is fixed to the top surface of the lower mold 1, and the top surface of the sealing gasket 19 contacts the bottom surface of the upper mold 3. A mounting groove 20 is provided on the top surface of the placement plate 2, and a slide rail 21 is fixed to the inner wall of the mounting groove 20. The top surface of the slider of the slide rail 21 is fixed to the bottom surface of the lower mold 1.

[0030] During use, the sealing gasket 19 can improve the sealing between the lower mold 1 and the upper mold 3. During the injection molding process of the injection mold body, if there is a gap between the lower mold 1 and the upper mold 3, the injection molding material may leak out, which will not only affect the injection molding effect, but may also pollute the injection molding environment and even damage the injection molding equipment. The sealing gasket 19 can fill the tiny gap between the upper mold 3 and the lower mold 1 to form a sealed injection molding space, ensuring that the raw material is effectively molded in the cavity inside the mold body, thereby improving the injection molding efficiency.

The slide rail 21 can reduce the friction between the lower mold 1 and the placement plate 2, which can facilitate the staff to remove the molded plastic product from the lower mold 1. Compared with the traditional fixed method, the movable lower mold 1 can provide a larger operating space and reduce the risk of damage to the product during demolding. At the same time, the movable lower mold 1 allows the staff to more easily approach various parts of the lower mold 1, thereby facilitating the cleaning, maintenance and inspection and maintenance of components such as the cooling system inside the lower mold 1.
