At the same time, a large amount of electrical energy will be consumed in the process of circulating the liquid through the electric drive component. After the consumed electrical energy is offset by the recovered heat energy, the actual recovered energy is low, that is, the heat recovery efficiency is low. Summary of the invention

[0006] In order to overcome the disadvantage of low heat energy recovery efficiency of the existing device, the present invention provides an injection molding machine for processing automobile interior trim panels.

[0012] As an improvement of the above scheme, it also includes a guide plate; the guide plate is fixedly connected to the cover shell; a cavity is formed between the second heat conducting plate, the cover shell, the guide cover and the guide plate; a channel is formed between the second heat conducting plate, the cover shell and the guide plate, and the channel is connected to the cavity.

[0013] As an improvement of the above scheme, it also includes a telescopic cylinder; the telescopic cylinder is fixedly connected to the cover shell, and the telescopic end of the telescopic cylinder is fixedly connected to the guide plate; the guide plate is elastic.

The plastic particles need to pass through the heat-conducting plate 2 during the unloading process, so that the plastic particles are preheated by the heat-conducting plate 2.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] An injection molding machine for processing automobile interior panels, such as Figure 1-Figure 4As shown, it includes a workbench 1, a mold 2, a heat-insulating shell 3 and an injection molding cylinder 4; the mold 2 is bolted to the workbench 1, and the workbench 1 is set to be made of alloy material; the heat-insulating shell 3 is bolted to the workbench 1; the injection molding cylinder 4 is bolted inside the heat-insulating shell 3, the injection molding cylinder 4 is bolted to the workbench 1, and the injection molding cylinder 4 is connected to the mold 2; it also includes a heat-conducting cylinder 5, a heat-conducting plate 1 6, a heat-conducting plate 2 7, a cover 8 and a funnel 9; the outer ring surface of the injection molding cylinder 4 is fixedly connected to the heat-conducting cylinder 5, and the heat-conducting cylinder 5 is located inside the heat-insulating shell 3 side; thirteen heat-conducting plates 6 are welded on the heat-conducting cylinder 5, and the heat-conducting plates 6 pass through the heat-insulating shell 3; all the heat-conducting plates 6 are bolted together with a heat-conducting plate 2 7 which is arranged obliquely; a cover 8 is bolted to the injection cylinder 4, and the cover 8 is located on the outside of the heat-conducting plate 2 7; each heat-conducting plate 6 is inserted into the inside of the cover 8; a funnel 9 is bolted to the cover 8, and the opening of the funnel 9 is located below the heat-conducting plate 2 7, and the funnel 9 is set to an alloy material; the funnel 9 passes through the heat-insulating shell 3 and the heat-conducting cylinder 5, and is connected with the injection cylinder 4.

[0032] The cover 8 is made of heat-insulating material to reduce heat loss.

[0033] The cover shell 8 is provided with a detachable cover plate, and after the cover plate is removed, it is easier for manual labor to clean the inside of the cover shell 8 .

[0034] It also includes a flow guide cover 10 ; the flow guide cover 10 is connected to and welded to the cover shell 8 and is used to guide the material so that the material can be more easily injected into the cover shell 8 .

[0035] First, the plastic particles are poured into the guide cover 10 through the external conveying mechanism, the plastic particles flow into the cover 8 from the guide cover 10, and are received on the upper side of the heat conducting plate 2 7, and then roll down obliquely along the upper side of the heat conducting plate 2 7 to the funnel 9, and then the plastic particles are guided to the injection molding cylinder 4 through the funnel 9, the injection molding cylinder 4 conveys the plastic particles to the left, and heats the plastic particles to heat the plastic particles into molten plastic, and then the injection molding cylinder 4 conveys the molten plastic to the mold 2 for injection molding operation, and forms an automobile interior trim panel in the mold cavity of the mold 2, and then the automobile interior trim panel obtained by injection molding is taken out by the external manipulator to complete the injection molding operation. In this process, the heat diffused from the injection molding cylinder 4 is collected by the heat conducting cylinder 5, and the heat conducting cylinder 5 absorbs the heat The heat is transferred to the heat transfer plate 1 6, and the heat transfer plate 1 6 transfers the heat to the heat transfer plate 2 7. During the feeding process, the plastic particles will roll along the surface of the heat transfer plate 2 7, so that the heat on the heat transfer plate 2 7 is transferred to the plastic particles, and the plastic particles are preheated to improve the subsequent heating efficiency of the plastic particles. When in use, the heat diffused from the injection cylinder 4 is collected by the heat transfer cylinder 5, and then the collected heat is transferred to the heat transfer plate 2 7 by the heat transfer plate 1 6. The plastic particles need to pass through the heat transfer plate 2 7 during the unloading process, so that the plastic particles are preheated by the heat transfer plate 2 7. Compared with the existing equipment structure, it is simpler and there is no need to use an electric drive component to control the circulating liquid to recover heat, thereby reducing power loss and improving heat recovery efficiency.

[0036] Example 2

[0037] On the basis of Example 1, Figure 3-Figure 5 As shown, a guide plate 11 is also included; the guide plate 11 is bolted to the cover 8, and the guide plate 11 is used to limit and guide the material; a cavity 91 is formed between the heat conducting plate 2 7, the cover 8, the guide cover 10 and the guide plate 11; a channel 92 is formed between the heat conducting plate 2 7, the cover 8 and the guide plate 11, and the channel 92 is connected to the cavity 91.

[0038] It also includes a telescopic cylinder 12; the cover 8 is bolted with the telescopic cylinder 12, and the telescopic end of the telescopic cylinder 12 is fixedly connected to the guide plate 11; the guide plate 11 is elastic, and the telescopic cylinder 12 is used to drive the end of the guide plate 11 to reciprocate up and down.

[0039] It also includes spacers 13; six spacers 13 are welded on the heat conducting plate 2 7, and the spacers 13 are set to be heat conducting material.

[0040] During the unloading process, after the plastic particles fall to the upper side of the heat conducting plate 27 in a columnar shape, since the upper side of the heat conducting plate 27 is relatively wide, the plastic particles cannot cover the heat conducting plate 27 within the width range after they are spread out, resulting in that when the plastic particles flow through the heat conducting plate 27, part of the upper side of the heat conducting plate 27 is not covered by the plastic particles, resulting in a decrease in the utilization rate of the heat conducting plate 27. Therefore, after the plastic particles fall to the upper side of the heat conducting plate 27 in a columnar shape, the guide plate 11 is used to limit and intercept the plastic particles, and some of the plastic particles will flow obliquely downward through the channel 92. The amount of plastic particles transported into the cavity 91 by the external conveying mechanism is greater than the amount of plastic particles flowing through the channel 92, so that the plastic particles are filled to half the height of the cavity 91, and then the amount of plastic particles transported into the cavity 91 by the external conveying mechanism is reduced, so that The amount of plastic particles flowing into and out of the cavity 91 tends to be balanced. At this time, the plastic particles in the cavity 91 always completely cover the channel 92, so that after the plastic particles flow out of the channel 92, they can cover the heat conducting plate 27 within a width range, and when the plastic particles flow obliquely downward on the upper side of the heat conducting plate 27, the partition bars 13 guide and limit the plastic particles to prevent the plastic particles from gathering at local positions of the heat conducting plate 27, so that the plastic particles can completely cover the upper side of the heat conducting plate 27 when flowing through the heat conducting plate 27, and then the various positions of the heat conducting plate 27 can be fully utilized during the preheating process. When in use, the guide plate 11 and the partition bars 13 cooperate to make the plastic particles completely cover the upper side of the heat conducting plate 27 when flowing through the heat conducting plate 27, and then the various positions of the heat conducting plate 27 can be fully utilized during the preheating process.

[0041] During the process of plastic particles passing through the channel 92, since the channel 92 is relatively narrow, the plastic particles are easily stuck. Therefore, the telescopic cylinder 12 drives the end of the elastic guide plate 11 to reciprocate up and down, so that the end of the guide plate 11 moves the plastic particles in the channel 92, allowing them to pass through the channel 92 smoothly and avoid getting stuck or blocked. When in use, the telescopic cylinder 12 and the guide plate 11 cooperate to move the plastic particles in the channel 92, allowing them to pass through the channel 92 smoothly and avoid getting stuck or blocked.

[0042] Example 3

[0043] On the basis of Example 2, Figure 5 and Figure 6 As shown, a friction block 14 is also included; a plurality of friction blocks 14 are welded on each partition bar 13, and the friction block 14 is fixedly connected to the heat conducting plate 2 7, and friction force is applied to one end of the material through the friction block 14.

[0044] It also includes a guide assembly; the guide assembly is connected to the partition bar 13; the guide assembly includes a guide bar 15 and a guide block 16; each partition bar 13 is welded with a guide bar 15; each friction block 14 is welded with a guide block 16, and the guide block 16 is fixedly connected to the corresponding guide bar 15. After the material splashes to the upper side of the guide bar 15 and the guide block 16, it flows back to the heat conduction plate 2 7 along the inclined surface of the guide bar 15 and the guide block 16.

[0045] The gap between two adjacent heat conducting plates 6 is set to a vacuum environment to prevent the heat on the heat conducting plates 6 from escaping.

[0046] When the plastic particles slide obliquely downward on the upper side of the heat conducting plate 27, one side of some of the plastic particles contacts the inclined surface of the friction block 14, so that the friction block 14 applies an upward friction force to the end of the plastic particles, and the other positions of the plastic particles will be subjected to the downward impact force from other plastic particles. The impact force and the friction force are in opposite directions, so that the plastic particles will roll over, thereby changing the contact surface between the plastic particles and the heat conducting plate 27, so that the preheating of each position of the plastic particles is more uniform. When in use, the friction block 14 applies an upward friction force to the end of the plastic particles, so that the plastic particles roll over on the heat conducting plate 27, so that the preheating of the plastic particles is more uniform.

[0047] During the unloading process, some plastic particles will splash to the upper side of the partition bar 13 and the friction block 14. Therefore, guide bars 15 and guide blocks 16 are set on the partition bar 13 and the friction block 14 to make the plastic particles splash to the inclined surfaces of the guide bars 15 and the guide blocks 16, and then the plastic particles roll down along the inclined surfaces back to the heat conducting plate 2 7, thereby changing the contact surface between the plastic particles and the heat conducting plate 2 7, making the plastic particles preheated more evenly. When in use, the guide bars 15 and the guide blocks 16 cooperate to make the plastic particles that were originally going to splash to the upper side of the partition bar 13 and the friction block 14 roll back to the heat conducting plate 2 7, and change the contact surface between the plastic particles and the heat conducting plate 2 7, making the plastic particles preheated more evenly.

Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
