Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically an injection mold for a printer paper feed guide plate. Background Technology

[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media. The paper guide is an important part of the printer, and the processing of the paper guide requires the use of injection molds.

[0003] A search revealed that patent application number 2021209257079 discloses a printer paper feed guide injection mold with rapid cooling effect. After injection molding, a water pump is started to deliver cooling water from the water tank to the annular cooling water tank through a water delivery pipe. The cooling water passes through the annular cooling water tank to rapidly cool the second mold, thereby achieving rapid cooling of the product. Then, the cooled water that has absorbed heat is sent to the cooling box through the water outlet pipe. After the cooling water is cooled in the cooling box, it flows back into the water tank through the first pipe to form a cooling cycle, effectively achieving rapid and continuous cooling of the product and effectively increasing the rapid cooling of the product. At the same time, a fan is started to blow air into the ventilation and heat dissipation slots, effectively increasing the air circulation in the ventilation and heat dissipation slots, achieving rapid heat exchange, and effectively increasing the heat dissipation efficiency of the second mold. The four first and second ventilation nets effectively ensure the air circulation in the box and the air box, achieving rapid exhaust of hot air.

[0004] However, the water pump and fan of the above-mentioned device are driven by independent motors, requiring two sets of power systems, which increases energy consumption. In addition, the two sets of drive devices require more space, increasing the difficulty of assembly and maintenance. Summary of the Invention

[0005] The purpose of this invention is to provide an injection mold for a printer paper feed guide plate, which has a simple structure, is energy-efficient, and reduces production costs.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A printer paper feed guide injection mold is provided, including an upper mold and a lower mold below the upper mold. A partition is fixedly connected to the inner wall of the lower mold, dividing the interior of the lower mold into a first cavity and a second cavity. A protective shell is fixedly connected to the bottom of the inner wall of the second cavity. A guide impeller is movably connected to the inner wall of the protective shell, one end of which penetrates the protective shell and is fixedly connected to a driven wheel. A fan housing is installed on the outer wall of the lower mold, and a motor is installed inside the fan housing. An air guide impeller is fixedly connected to the output end of the motor. One end of the air guide impeller penetrates the fan housing and is fixedly connected to a drive wheel. The driven wheel is connected to the drive wheel via a synchronous belt. A flow guide channel is opened inside the top of the lower mold. A return pipe is fixedly connected to the outer wall of the lower mold. The bottom of the return pipe penetrates the lower mold and is fixedly connected to the outer wall of the partition. A flow guide pipe is fixedly connected to the front end of the protective shell. The top of the flow guide pipe communicates with the flow guide channel. A water inlet pipe is fixedly connected to the rear end of the protective shell. The other end of the water inlet pipe is fixedly connected to the outer wall of the partition.

[0007] Optionally, the upper part of the inner wall of the lower mold is provided with a through hole, and the number of through holes is multiple. The upper part of the lower mold is provided with a protruding plate, and the multiple through holes extend into the interior of the protruding plate.

[0008] Optionally, a feed pipe is fixedly connected to the top of the upper mold, and a feed inlet is fixedly connected to the top of the feed pipe, the feed inlet being funnel-shaped.

[0009] Optionally, the outer wall of the lower mold is fixedly connected with a connecting pipe, and there are two connecting pipes, with a solenoid valve installed on the top of each of the two connecting pipes.

[0010] Optionally, a breathable mesh is installed on the left outer wall of the lower mold, the breathable mesh being installed higher than the partition, and a hollow groove is provided on the outer wall of the upper mold.

[0011] Optionally, the lower mold has a positioning hole at its top, and there are multiple positioning holes. The upper mold is fixedly connected to a positioning post at its bottom, and there are multiple positioning posts. The multiple positioning posts are located inside the multiple positioning holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model includes a protective shell, a guide impeller, a driven wheel, a fan housing, a motor, an air guide impeller, a drive wheel, a synchronous belt, a return pipe, a guide pipe, and a water inlet pipe. After the upper and lower molds are pressed together, because the lower mold has a protruding plate on its top and the upper mold has a forming cavity at its bottom, the top of the protruding plate is not completely attached to the top of the inner wall of the forming cavity. The raw material flows through the feed inlet and feed pipe into the gap between the protruding plate and the forming cavity. Then the motor works, driving the air guide impeller and the drive wheel to rotate. The drive wheel, connected to the driven wheel via a synchronous belt, drives the driven wheel and the guide impeller to rotate synchronously. As the guide impeller rotates, it extracts heat from the lower mold. Simultaneously, as the guide impeller rotates, the coolant in the first cavity enters the protective shell through the inlet pipe. With the rotation of the guide impeller, it enters the guide channel through the guide pipe, carrying the heat generated by the injection molded part into the return pipe. Since the return pipe is S-shaped, the heat returns to the first cavity. This invention features a simple structure, makes the device more energy-efficient, and reduces production costs.

[0014] 2. This utility model is equipped with connecting pipes, solenoid valves, venting mesh, and positioning holes. Two connecting pipes are provided on the outer wall of the lower mold, allowing coolant to be added to the first cavity through the upper connecting pipe. The coolant inside the first cavity can be extracted through the lower connecting pipe and the solenoid valve connected to the top. Multiple through holes are provided, extending into the protruding plate at the top of the lower mold, allowing the heat generated by the injection molded part to dissipate through the through holes. A venting mesh is installed on the left side of the lower mold. When the air guide impeller rotates, air enters the interior of the lower mold from the left side and exits from the right side of the fan housing. Multiple positioning pins are provided at the bottom of the upper mold, and multiple positioning holes are provided at the top of the lower mold, which can play a positioning role when the upper mold and the lower mold are pressed together.

[0031] Reference Figure 1-10 This invention provides a printer paper feed guide injection mold according to an embodiment of the present invention. The printer paper feed guide injection mold includes an upper mold 1 with a vent hole at its top. A lower mold 2 is located below the upper mold 1. A partition 3 is fixedly connected to the inner wall of the lower mold 2, dividing the interior of the lower mold 2 into a first cavity 4 and a second cavity 5. A protective shell 6 is fixedly connected to the bottom of the inner wall of the second cavity 5. A guide impeller 7 is movably connected to the inner wall of the protective shell 6, with one end of the guide impeller 7 penetrating the protective shell 6 and fixedly connected to a driven wheel 8. A fan housing 9 is installed on the outer wall of the lower mold 2, and a motor 10 is installed inside the fan housing 9. An air guide impeller 11 is fixedly connected to the output end of the motor 10, guiding the air... One end of the impeller 11 passes through the fan housing 9 and is fixedly connected to the drive wheel 12. The driven wheel 8 is connected to the drive wheel 12 via the synchronous belt 13. A guide channel 14 is opened inside the top of the lower mold 2. A return pipe 15 is fixedly connected to the outer wall of the lower mold 2.
