Description

Technical Field

[0001] This utility model relates to the field of automotive interior panel processing technology, specifically to a mold for processing automotive interior panels. Background Technology

[0002] Automotive interior trim panels are an important component of car interior decoration. They are installed in various parts of the car interior, such as the inside of the doors, around the dashboard, seat backs, and the roof. Their function is not only to enhance the aesthetics of the interior and create a comfortable and luxurious driving environment, but also to provide certain functionalities. With the development of the automotive industry, automotive interior trim panels are increasingly focusing on human-centered and personalized designs, striving to showcase a unique style while ensuring quality, in order to meet the diverse needs of the market.

[0003] Automotive interior panels are typically made of plastic and are therefore processed using injection molding. To ensure smooth demolding after molding, operators need to spray a release agent onto the surface of the mold before injection molding. However, manual spraying is slow and uneven, which can easily lead to poor demolding results. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for processing automotive interior panels, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A mold for processing automotive interior panels includes a U-shaped frame. A concave mold is installed on one inner wall of the U-shaped frame, and a convex mold is installed on the other inner wall. A hydraulic cylinder is installed on the outer surface of the U-shaped frame, and the end of the hydraulic cylinder's extension / retraction end is connected to the convex mold. A hollow tube is installed below the top horizontal plate of the U-shaped frame via a translation mechanism, and the hollow tube is positioned between the concave and convex molds. Multiple atomizing nozzles are installed vertically on both outer surfaces of the hollow tube. A spraying mechanism is provided at the top of the U-shaped frame to inject a release agent into the hollow tube.

[0007] It can be seen that by setting up the translation mechanism and the spraying mechanism, the hollow tube can be driven to move at a constant speed between the cavity and the hollow tube, so that the release agent can be evenly sprayed from the atomizing nozzle onto the surface of the cavity and the punch, achieving the purpose of automatic spraying, and the spraying is uniform and the demolding effect is good.

[0008] Furthermore, the translation mechanism includes a through slot formed in the top horizontal plate of the U-shaped frame. A slider is slidably mounted inside the through slot, and a hollow tube is installed on the lower surface of the slider. A threaded rod is rotatably connected between the two inner walls of the through slot, passing through the interior of the slider and threadedly connected to it. A servo motor is mounted on the side surface of the U-shaped frame, and the output shaft of the servo motor is connected to the threaded rod. A limit rod is connected between the two inner walls of the through slot, and the slider is slidably mounted on the limit rod.

[0009] Furthermore, the spraying mechanism includes a liquid storage tank mounted on top of the U-shaped frame. A pump body is mounted on the outer surface of the liquid storage tank. The input end of the pump body is connected to a suction pipe, the end of which extends to the lower side of the interior of the liquid storage tank. The output end of the pump body is connected to a flexible hose, the end of which is connected to the upper surface of the slider and communicates with the hollow tube.

[0010] Furthermore, collection boxes are installed on both inner walls of the U-shaped frame, and drain pipes are installed on the outer surface of the collection boxes, with valves installed inside the drain pipes.

[0011] Furthermore, the inside of the collection box is equipped with a removable filter.

[0012] Furthermore, a cylinder is installed on the outer surface of the U-shaped frame, and an I-shaped plate is installed at the end of the cylinder's telescopic end. A push rod is connected to each of the four corners of the I-shaped plate, and through holes are opened at each of the four corners inside the die, with the push rods set inside the through holes.

[0013] Furthermore, a guide post is installed on the side of the punch away from the die, and the end of the guide post slides through to the other side of the U-shaped frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model, through the setting of translation mechanism and spraying mechanism, can drive the hollow tube to move at a constant speed between the cavity mold and the hollow tube, thereby enabling the release agent to be evenly sprayed from the atomizing nozzle onto the surface of the cavity mold and the punch mold, achieving the purpose of automatic spraying, and the spraying is uniform and the demolding effect is good.

[0016] 2. By setting up a collection box, since the concave and convex molds are vertically arranged, after the release agent is sprayed on the surface of the concave and convex molds, the excess release agent can flow downward under the action of gravity and fall into the collection box, thereby achieving the purpose of recycling the release agent, reducing losses and improving resource utilization.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 This utility model provides a mold for processing automotive interior panels, including a U-shaped frame 1. A concave mold 101 is installed on one inner wall of the U-shaped frame 1, and a convex mold 102 is provided on the other inner wall of the U-shaped frame 1. A hydraulic cylinder 103 is installed on the outer surface of the U-shaped frame 1, and the end of the extension and retraction end of the hydraulic cylinder 103 is connected to the convex mold 102. A hollow tube 104 is installed below the top horizontal plate of the U-shaped frame 1 through a translation mechanism 2, and the hollow tube 104 is located between the concave mold 101 and the convex mold 102. Multiple atomizing nozzles 105 are installed on both outer surfaces of the hollow tube 104 in a vertical direction. A spraying mechanism 3 is provided at the top of the U-shaped frame 1 to inject a release agent into the hollow tube 104.

[0024] In use, the translation mechanism 2 drives the hollow tube 104 to move at a constant speed between the concave mold 101 and the hollow tube 104. During its movement, the release agent is injected into the hollow tube 104 by the spraying mechanism 3, and then sprayed evenly on the surface of the concave mold 101 and the convex mold 102 by the atomizing nozzles 105 on both sides, so as to achieve the purpose of automatic spraying, and the spraying is uniform and the release effect is good.

[0025] After the hollow tube 104 moves to the end, it is located outside the cavity 101 and the punch 102. At this time, the hydraulic cylinder 103 is activated to drive the punch 102 to close with the cavity 101. Then, the injection molding liquid is injected into the cavity 101 and the punch 102 through the injection tube (not shown in the figure) on the outer surface of the punch 102. After it cools and solidifies, the punch 102 is opened, and the product can be easily taken out.

[0026] Preferably, the translation mechanism 2 includes a through groove 201 formed in the top horizontal plate of the U-shaped frame 1. A slider 202 is slidably mounted inside the through groove 201, and a hollow tube 104 is mounted on the lower surface of the slider 202. A threaded rod 203 is rotatably connected between the two inner walls of the through groove 201. The threaded rod 203 passes through the inside of the slider 202 and is threadedly connected to it. A servo motor 204 is mounted on the side surface of the U-shaped frame 1, and the output shaft of the servo motor 204 is connected to the threaded rod 203. A limit rod 205 is connected between the two inner walls of the through groove 201, and the slider 202 is slidably mounted on the limit rod 205.

[0027] When the servo motor 204 is started, it drives the threaded rod 203 to rotate. Due to the combined limiting effect of the inner wall of the through groove 201 and the limiting rod 205, the slider 202 can move horizontally along the length direction of the threaded rod 203 under the drive of the threaded connection, thereby driving the hollow tube 104 to move horizontally at a constant speed between the die 101 and the punch 102.

[0028] Preferably, the spraying mechanism 3 includes a liquid storage tank 301 mounted on top of the U-shaped frame 1. A pump body 302 is mounted on the outer surface of the liquid storage tank 301. An extraction pipe is connected to the input end of the pump body 302, and the end of the extraction pipe extends to the lower side inside the liquid storage tank 301. A hose 303 is connected to the output end of the pump body 302. The end of the hose 303 is connected to the upper surface of the slider 202, and the hose 303 communicates with the hollow tube 104.

[0029] The top of the liquid storage tank 301 is provided with an injection port, and the inside of the injection port is provided with a cap. When the release agent is added into the liquid storage tank 301, when the pump body 302 is started, the release agent can be drawn out from the liquid storage tank 301 and injected into the hollow tube 104 through the hose 303 to achieve the purpose of spraying.

[0030] The liquid storage tank 301 is also equipped with a liquid level sensor (not shown in the figure) to monitor the remaining amount of release agent in real time, so that the operator can replenish the release agent in time, ensure its continuous supply, and avoid the pump body 302 running dry.

[0031] Preferably, a collection box 4 is installed on both inner walls of the U-shaped frame 1, and a drain pipe 401 is installed on the outer surface of the collection box 4. A valve 402 is installed inside the drain pipe 401.

[0032] With the collection box 4 in place, since the concave mold 101 and convex mold 102 are vertically arranged, when the release agent is sprayed on the surface of the concave mold 101 and convex mold 102, the excess release agent can flow downward under the action of gravity and fall into the collection box 4, thereby achieving the purpose of recycling the release agent, reducing losses and improving resource utilization.

[0033] Preferably, the inside of the collection box 4 is provided with a removable filter screen 5.

[0034] The filter screen 5 prevents debris generated during processing from falling into the collection box 4 and affecting the purity of the release agent collected inside.

[0035] Preferably, a cylinder 6 is installed on the outer surface of the U-shaped frame 1, and an I-shaped plate 601 is installed at the end of the telescopic end of the cylinder 6. A push rod 602 is connected to each of the four corners of the I-shaped plate 601, and through holes 603 are opened at each of the four corners inside the die 101, with the push rod 602 set in the through hole 603.

[0036] When the cylinder 6 is activated, its telescopic end drives the I-shaped plate 601 to approach the U-shaped frame 1, which in turn drives the ejector rod 602 to extend out from the through hole 603, ejecting the product and achieving the purpose of rapid demolding. The setting of four ejector rods 602 can ensure that the product is subjected to uniform force during ejection, thus ensuring the integrity of the product.

[0037] Preferably, a guide post 7 is installed on the side of the punch 102 away from the die 101, and the end of the guide post 7 slides through to the other side of the U-shaped frame 1.

[0038] By setting the guide post 7, the punch 102 can be supported and guided, so that it can be accurately closed with the die 101, avoiding leakage of injection liquid.
