Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and specifically relates to an injection mold with good cooling effect. Background Technique

[0002] After injection molding, the injection mold needs to wait for the hot fluid plastic in the mold cavity to cool and solidify, and then a formed product is obtained. During injection molding, the temperature at the bottom of the injection mold rises. In order to accelerate the cooling and solidification time of the plastic, a cooling structure is usually installed at the bottom of the injection mold to dissipate heat from the bottom of the injection mold after injection molding, thereby accelerating the cooling and solidification time of the hot fluid plastic.

[0003] At present, although the cooling structure of the mold has a good cooling effect, it does not have a preheating function. After the first injection molding and cooling at the bottom of the mold, the temperature in the mold cavity is relatively low. When the second injection molding is carried out without preheating, it may cause the hot fluid plastic that has just entered the mold cavity to start to cool and solidify before it has fully flowed and filled the mold cavity, affecting the flow of the subsequent injected hot fluid plastic, and ultimately affecting the quality of the mold injection products. Content of the Utility Model

[0004] The purpose of the utility model is to provide an injection mold with good cooling effect to solve the problem that the temperature in the mold cavity is relatively low after the mold is cooled, which is likely to affect the quality of the second injection molding as mentioned in the above background technique.

A lifting component is installed in the middle of the outer wall of the top of the base, and two mounting plates are installed on the outer wall of the top of the base. A lower mold is installed on the outer wall of one side of the two mounting plates, and a first electric push rod is installed at one end of the outer wall of the top of the base. The top of the piston rod of the first electric push rod is installed with an upper mold, and an injection pipe is connected to the top of the upper mold.

[0006] The displacement component includes a double-sliding table linear motor, a moving plate installed on two sliding parts of the double-sliding table linear motor, and brackets fixed at the four corners of the outer wall of the top of the two moving plates.

[0022] Please refer to Figure 1-7 , an injection mold with a good cooling effect provided by the present invention includes: a base 1, and further includes: a chute 2 opened on the outer wall of the top of the base 1, a displacement component 3 is installed on the inner wall of the chute 2, and a heating component 4 and a cooling component 5 are respectively placed at both ends of the top of the displacement component 3. A lifting component 6 is installed in the middle of the outer wall of the top of the base 1, and two mounting plates 7 are installed on the outer wall of the top of the base 1. The same lower mold 8 is installed on the outer wall of one side of the two mounting plates 7, and a first electric push rod 9 is installed at one end of the outer wall of the top of the base 1. The top of the piston rod of the first electric push rod 9 is installed with an upper mold 10, and an injection pipe 11 is connected to the top of the upper mold 10.

[0023] In a specific application scenario, by the contraction of the piston rod of the first electric push rod 9, the upper die 10 and the lower die 8 can be combined together. The hot fluid plastic can be injected into the mold cavity by using the injection tube 11. After injection, the cooling component 5 can be moved to directly below the lower die 8 through the displacement component 3. At this time, the cooling component 5 can be lifted from the displacement component 3 through the lifting component 6, so that the cooling component 5 is attached to the bottom of the lower die 8. The cooling component 5 is used to dissipate heat from the bottom of the lower die 8, accelerating the cooling and solidification time of the hot fluid plastic. After cooling, by the rising of the piston rod of the first electric push rod 9, the upper die 10 is driven to rise, and the finished product can be taken out from the lower die 8. After taking out, by the contraction of the piston rod of the first electric push rod 9 again, the upper die 10 and the lower die 8 can be combined together to prepare for the next injection. Before injection, the cooling component 5 can be placed back on the displacement component 3 through the lifting component 6. The heating component 4 is moved to directly below the lower die 8 by using the displacement component 3, and the heating component 4 is lifted from the displacement component 3 through the lifting component 6, so that the heating component 4 is attached to the bottom of the lower die 8 to heat the lower die 8, achieving a preheating effect before injection, enabling the hot fluid plastic to flow fully in the mold cavity during the second injection and ensuring the quality of the injection product.

[0024] In a preferred embodiment, the displacement component 3 includes a double-sliding table linear motor 301, a moving plate 302 mounted on two sliding members of the double-sliding table linear motor 301, and brackets 303 fixed at the four corners of the outer wall of the top of the two moving plates 302.

[0025] In a specific application scenario, the heating component 4 and the cooling component 5 can be respectively placed on the two brackets 303, and the double-sliding table linear motor 301 can be used to drive the heating component 4 and the cooling component 5 to move respectively.

[0026] In a preferred embodiment, the heating component 4 includes a heating plate 401, a hot water pipeline 402 opened in the plate body of the heating plate 401, a hot water inlet pipe 403 connected to one end of the hot water pipeline 402, a hot water outlet pipe 404 connected to the other end of the hot water pipeline 402, and a heating mark 405 provided on the outer wall of the top of the heating plate 401.

[0027] In a specific application scenario, hot water can enter the hot water pipeline 402 from the hot water inlet pipe 403 and then flow out from the hot water outlet pipe 404 to increase the temperature of the heating plate 401, and the mold can be preheated.

[0028] In a preferred embodiment, the cooling component 5 includes a cooling plate 501, a cold water pipeline 502 opened in the plate body of the cooling plate 501, a cold water inlet pipe 503 connected to one end of the cold water pipeline 502, a cold water outlet pipe 504 connected to the other end of the cold water pipeline 502, and a cooling mark 505 provided on the outer wall of the top of the cooling plate 501.

[0029] In a specific application scenario, cold water can enter the cold water pipeline 502 through the cold water inlet pipe 503, and then flow out through the cold water outlet pipe 504 to reduce the temperature of the cooling plate 501, thereby absorbing heat from the mold to lower its temperature.

[0030] In a preferred embodiment, the lifting assembly 6 includes a mounting frame 601, a second electric push rod 602 mounted on the outer wall of one side of the mounting frame 601, a support plate 603 mounted on the top of the piston rod of the second electric push rod 602, and limit rods 604 fixed to the four corners of the outer wall of the top of the support plate 603.

[0031] In a specific application scenario, the second electric push rod 602 can push the support plate 603 to rise, and through the support plate 603, the heating plate 401 or the cooling plate 501 can be lifted and attached to the bottom of the mold.

[0032] In a preferred embodiment, the first electric push rod 9, the second electric push rod 602, and the double-slider linear motor 301 are all connected to an external power source through power lines.

[0033] In a specific application scenario, the first electric push rod 9, the second electric push rod 602, and the double-slider linear motor 301 can be powered on and operate.

[0034] Working principle: The heating plate 401 and the cooling plate 501 can be respectively placed on two brackets 303. The double-slider linear motor 301 can be used to drive the heating plate 401 and the cooling plate 501 to move respectively. By the contraction of the piston rod of the first electric push rod 9, the upper mold 10 and the lower mold 8 can be closed together. The hot fluid plastic can be injected into the mold cavity through the injection pipe 11. After injection, the cooling plate 501 can be moved directly below the lower mold 8 through the double-slider linear motor 301. At this time, the second electric push rod 602 can be used to push the support plate 603 to rise, and through the support plate 603, the cooling plate 501 can be lifted and attached to the bottom of the lower mold 8. Cold water can enter the cold water pipeline 502 through the cold water inlet pipe 503, and then flow out through the cold water outlet pipe 504 to reduce the temperature of the cooling plate 501, thereby absorbing heat from the mold to lower its temperature and accelerating the cooling and solidification time of the hot fluid plastic;

[0035] After cooling, by the rising of the piston rod of the first electric push rod 9, the upper mold 10 is driven to rise, and the finished product can be taken out from the lower mold 8. After taking out, the upper mold 10 and the lower mold 8 can be closed together again by the contraction of the piston rod of the first electric push rod 9 to prepare for the next injection molding;

[0036] Before injection molding, the cooling plate 501 can be placed back on the corresponding bracket 303 by retracting the piston rod of the second electric push rod 602. Then, the cooling plate 501 is moved away by the double-slide linear motor 301, and the heating plate 401 is moved to directly below the lower mold 8. The second electric push rod 602 is used to push the support plate 603 upward, and the heating plate 401 is lifted by the support plate 603 and attached to the bottom of the lower mold 8 to heat the lower mold 8, achieving a preheating effect on the inside of the mold cavity before injection molding, so that the hot-fluid plastic can flow fully in the mold cavity during secondary injection molding. The mold can be preheated and cooled respectively before and after injection molding to ensure the quality of the injection-molded product.
