[0008] Preferably, a telescopic cylinder is provided at the upper end of the machine body, the upper end of the lifting seat is fixedly connected to the output end of the telescopic cylinder, and the upper mold is fixedly connected to the lower end of the lifting seat.

[0009] Preferably, the lower mold and the upper end of the fixed seat are fixedly connected, the fixed seat and the base are fixedly connected, and the pressure plate and the inner side of the fixed seat are slidably sleeved.

[0010] Preferably, the lower end of the transmission block is fixedly connected to the pressure plate, the upper end of the transmission block extends to the outside of the fixed seat through the through groove, the transmission block and the inner side of the through groove are slidably connected, and the lower end of the pressure block and the upper end of the transmission block are adapted to each other.

[0011] Preferably, the upper end of the spring is fixedly connected to the pressure plate, and the lower end of the spring is fixedly connected to the inner side of the fixing seat.

[0012] Preferably, the inner sides of the sealing block and the sealing groove are adapted to each other, the upper end of the air cylinder is fixedly connected to the sealing block, the lower end of the air cylinder extends through the through hole to the inner side of the fixed seat and is fixedly connected to the pressure plate, the air cylinder and the inner side of the through hole are slidably sleeved, and an air hole is opened on the side of the upper end of the air cylinder.

[0014] The beneficial effects of this utility model are:

[0015] This automotive dashboard front cover injection molding device uses a lifting seat to detach the upper mold from the lower mold, causing the pressure block to detach from the transmission block. At this time, the pressure plate, under the elastic force of the spring, drives the sealing block to rise. Simultaneously, the air pump operates, allowing airflow to pass through the air chamber and hose into the air cylinder, and then be ejected from the air holes on the surface of the air cylinder. This allows the injection molded part to separate from the lower mold under the combined action of the airflow and the sealing block, achieving rapid demolding and ejection of the injection molded part. This increases the material feeding rate of the injection molding device, and the molded automotive dashboard front cover is subjected to more uniform force during material feeding, effectively avoiding damage to the workpiece caused by direct ejection.

[0023] Please see Figures 1-5 This utility model provides an embodiment of an injection molding device for a car dashboard front cover, including a base 1, a body 2 at the upper end of the base 1, a lifting seat 3 on the right side of the body 2, an upper mold 4 at the lower end of the lifting seat 3, a lower mold 5 below the upper mold 4, a fixed seat 6 at the lower end of the lower mold 5, a pressure plate 7 inside the fixed seat 6, transmission blocks 8 on the left and right sides of the upper end of the pressure plate 7, pressure blocks 9 fixedly installed on the left and right sides of the lower end of the lifting seat 3, a spring 10 at the lower end of the pressure plate 7, a sealing groove 11 inside the lower mold 5, a sealing block 12 inside the sealing groove 11, and a sealing block 12 at the lower end of the sealing block 12. An air cylinder 13 is provided, and an air chamber 14 is provided at the lower end of the fixed base 6. An air pump 15 is provided at the lower end of the air chamber 14. The sealing block 12 is driven to rise by the pressure plate 7 under the elastic force of the spring 10. At the same time, the air pump 15 works to make the air flow out from the air holes on the surface of the air cylinder 13. Under the dual action of the air flow and the sealing block 12, the injection molded part is separated from the lower mold 5, realizing the rapid demolding and ejection of the injection molded part.

[0024] Please see Figures 1-5In this embodiment, a telescopic cylinder is provided at the upper end of the machine body 2. The upper end of the lifting seat 3 is fixedly connected to the output end of the telescopic cylinder. The upper mold 4 is fixedly connected to the lower end of the lifting seat 3. The lower mold 5 is fixedly connected to the upper end of the fixed seat 6. The fixed seat 6 is fixedly connected to the base 1. The pressure plate 7 is slidably sleeved with the inner side of the fixed seat 6. The lower end of the transmission block 8 is fixedly connected to the pressure plate 7. The upper end of the transmission block 8 extends to the outer side of the fixed seat 6 through a through groove. The transmission block 8 is slidably connected with the inner side of the through groove. The lower end of the pressure block 9 and the upper end of the transmission block 8 are mutually adapted. The upper end of the spring 10 is connected to the pressure plate. 7. Fixed connection: The lower end of spring 10 is fixedly connected to the inner side of fixed seat 6. The inner sides of sealing block 12 and sealing groove 11 are adapted to each other. The upper end of air cylinder 13 is fixedly connected to sealing block 12. The lower end of air cylinder 13 extends through through hole to the inner side of fixed seat 6 and is fixedly connected to pressure plate 7. Air cylinder 13 and the inner side of through hole are slidably sleeved. Air hole is opened on the side of upper end of air cylinder 13. The upper mold 4 and lower mold 5 are closed by lifting seat 3. At this time, pressure block 9 drives transmission block 8 to descend, so that pressure plate 7 drives sealing block 12 to fit with the inner side of sealing groove 11, which facilitates injection molding.

[0025] Please see Figures 2-5 In this embodiment, the lower ends of the air chamber 14 and the fixed base 6 are fixedly connected. The air cylinder 13 and the air chamber 14 are connected to each other through a hose. The output end of the air pump 15 is connected to the air chamber 14. After the injection molding is completed, the lifting base 3 drives the upper mold 4 to disengage from the lower mold 5, and the pressure block 9 disengages from the transmission block 8. At this time, the pressure plate 7 drives the sealing block 12 to rise under the elastic force of the spring 10. At the same time, the air pump 15 works to make the airflow pass through the air chamber 14 and the hose into the air cylinder 13, and spray out from the air hole on the surface of the air cylinder 13. Under the dual action of the airflow and the sealing block 12, the injection molded part is separated from the lower mold 5, realizing the rapid demolding and ejection of the injection molded part.

[0026] During operation, the lifting seat 3 drives the upper mold 4 and lower mold 5 to close. At this time, the pressure block 9 drives the transmission block 8 to descend, so that the pressure plate 7 drives the sealing block 12 to fit against the inner side of the sealing groove 11, which facilitates the injection molding process. After the injection molding is completed, the lifting seat 3 drives the upper mold 4 to disengage from the lower mold 5, and the pressure block 9 disengages from the transmission block 8. At this time, the pressure plate 7 drives the sealing block 12 to rise under the elastic force of the spring 10. At the same time, the air pump 15 works, so that the airflow passes through the air chamber 14 and the hose to enter the air cylinder 13 and is ejected from the air holes on the surface of the air cylinder 13. Under the dual action of the airflow and the sealing block 12, the injection molded part separates from the lower mold 5, realizing the rapid demolding and ejection of the injection molded part.

[0027] Through the above steps, the pressure plate 7 drives the sealing block 12 to rise under the elastic force of the spring 10. At the same time, the air pump 15 works to spray air from the air holes on the surface of the air cylinder 13. Under the dual action of the air flow and the sealing block 12, the injection molded part separates from the lower mold 5. This solves the problem that the injection molding device for the front cover of the car dashboard is difficult to demold during use, lacks an auxiliary demolding structure, and causes time-consuming and labor-intensive demolding, and is prone to damage to the molded front cover of the car dashboard.
