Description

Technical Field

[0001] The present invention relates to the technical field of injection molds, and more particularly to an injection mold for a vehicle lamp. Background Art

[0002] As the appearance and functions of current car lights become more and more diversified, the requirements for car light molds are also getting higher and higher. Injection molding is used for car light injection molding, which is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, and precise product size. Using car light injection molds can quickly produce high-quality car lights.

[0003] There are some problems with existing headlight injection molds during actual use, as follows:

[0004] First, when the movable mold and the fixed mold of the existing car lamp injection mold are fitted together, the injection rod needs to be connected to the mold hole to keep the movable mold and the fixed mold connected and fixed. However, after a long period of mold opening and closing, the friction between the injection rod and the mold hole causes the connecting rod to wear, affecting the fixation of the mold.

[0005] Secondly, the existing car light injection mold controls the fit between the movable mold and the fixed mold during injection molding through a control system. When there is a deviation in the system data, the size of the car light produced by injection molding does not meet the requirements, affecting the quality of car light production.

[0006] Third, the headlights contain multiple clips for easy installation. There are many clips on the headlights. If the clips are not cooled enough after injection molding, they will stick to the mold, causing a waste of resources. Summary of the Invention

The shape and quality of the headlights have an important position in the development process of the automotive industry. Due to the rapid development of my country's economy, the increase in the number of cars purchased by people has led to higher requirements for the quality of headlights. Car lights are mainly used for lighting. The shapes of the headlights used for lights with different functions are also different. The headlights are mainly manufactured using the injection molding process. The relevant parameters of the headlights are recorded in a timely manner and then the matching work is carried out. The plastic melt is then plasticized and then punched, cooled and shaped. After this series of work processes, high-quality headlight components are created. The current large number of car brands has also led to increased competitiveness in the automotive industry. However, the wide variety of car headlight production processes has led to different types of defects. Therefore, research in this area can help us grasp the core technology and enhance the core competitiveness of the enterprise. In the traditional injection molding process, designers draw drawings of headlight molds based on relevant experience, but in the actual process, no parameter calculations are performed, resulting in problems during the mold trial process. The drawings must be revised again, and the repetition of processes leads to increased labor costs, which is not conducive to improving production efficiency.Headlight molds play an important role in the appearance of cars. They play an important role in the process of headlight modification. In particular, people have high requirements for car lights and need to conduct technical research on molds.

[0032] The time required to complete an injection molding process is called the molding cycle, also known as the molding cycle. The molding cycle directly affects labor productivity and equipment utilization. Therefore, in the production process, the relevant time in the molding cycle should be shortened as much as possible under the premise of ensuring quality. In the entire molding cycle, injection time and cooling time are the most important, and they have a decisive influence on the quality of the product. The filling time in the injection time is directly inversely proportional to the filling rate. The holding time in the injection time is the pressure time of the plastic in the mold cavity, which accounts for a large proportion of the entire injection time. Before the melt freezes at the gate, the amount of holding time affects the dimensional accuracy of the product, and the holding time also has the most The benefit value is known to depend on the material temperature, mold temperature, and the size of the main channel and gate. If the size of the main channel and gate and the process conditions are normal, the pressure value with the smallest fluctuation range of the product shrinkage rate is usually used as the basis. The cooling time is mainly determined by the thickness of the product, the thermal properties and crystallization properties of the plastic, and the mold temperature. The end point of the cooling time should be based on the principle of ensuring that the product does not cause changes when demolding. It is unnecessary to have a too long cooling time, which not only reduces production efficiency but also makes demolding difficult for complex parts. It may even generate demolding stress when forced demolding. The other time in the molding cycle is related to whether the production process is continuous and automated, as well as the degree of continuity and automation.

[0033] In a preferred embodiment, when the fixed mold 1 and the movable mold 2 are fitted, the extrusion block 6 is fitted with the extrusion groove 201, and when the extrusion block 6 and the extrusion groove 201 are fitted, the overall shape of the lamp is formed. After the plastic melt is transported from the liquid guide pipe 104 to the extrusion groove 201, the plastic melt is extruded into the shape of the lamp by connecting and fixing the extrusion block 6 and the extrusion groove 201. After cooling and shaping, the fixed mold 1 and the movable mold 2 are separated to obtain the injection-molded lamp model. At the same time, the front surface of the front fixing plate 4 is fitted with the back surface of the closing block 7, and the hook 302 is fitted with the fixing groove 701. When the front fixing plate 4 and the closing block 7 are fitted, the hook 302 is fitted with the fixing groove 701. 01 is connected and fixed. When there is a gap between the fixed mold 1 and the movable mold 2, so that the extrusion block 6 cannot completely fit with the extrusion groove 201, when the plastic melt is input into the extrusion groove 201 from the liquid guide pipe 104, the plastic melt will overflow from the gap between the fixed mold 1 and the movable mold 2, and the extrusion groove 201 cannot be completely filled with the plastic melt, resulting in the quality of the car light model produced by injection molding being unqualified. Therefore, when the hook 302 is within the range of the fixed groove 701 but does not completely fit with the fixed groove 701, the system issues an alarm, so that the production personnel can promptly discover the deviation of the car light injection mold and make timely adjustments to ensure the quality of automobile injection molding production.

[0034] In a preferred embodiment, when the fixed mold 1 and the movable mold 2 are fitted together, the powerful fan 103 is located above the fixed mold 1, and the fixed mold 1 and the movable mold 2 are fitted together for car light injection molding production. At this time, the powerful fan 103 is not needed, so the powerful fan 103 located above the fixed mold 1 and the movable mold 2 will not hinder the movement of the movable mold 2. When the fixed mold 1 and the movable mold 2 are separated, the powerful fan 103 is located in the middle of the extrusion groove 201, and the powerful fan 103 blows out strong wind force in the direction of the movable mold 2, thereby reducing the temperature of the extrusion groove 201 and the car light model injection molded in the extrusion groove 201. The number of clips 601 is large and the size is small. The powerful fan 103 assists in cooling so that the position of the clips 601 in the extrusion groove 201 is uniform and the temperature is quickly cooled, thereby preventing the clips 601 from sticking to the extrusion groove 201 after injection molding.

[0035] In a preferred embodiment, the powerful fan 103 contains a motor inside, and the control system transmits power to the motor inside the powerful fan 103, and the motor outputs electrical energy to the outside, thereby driving the blades inside the powerful fan 103 to rotate. The powerful fan 103 contains a turbo fan. The powerful fan 103 can allow the wind to be blown out in a spiral shape along a certain direction. As the blades stir, a spiral columnar wind can eventually be formed. The wind blown out by the powerful fan 103 has a long distance and good directionality. After blowing out to the middle of the movable mold 2, it disperses toward various parts of the extrusion groove 201. The purpose of the powerful fan 103 is to stir the air so that the air around the fixed mold 1 and the movable mold 2 forms a convection cycle, accelerating the air circulation speed. Since the wind speed and wind force of the powerful fan 103 are large, the air around the fixed mold 1 and the movable mold 2 can be quickly exchanged, so that the temperature of the movable mold 2 drops rapidly, which will not affect the production of car light injection molding.

[0036] In a preferred embodiment, the front face of the front fixing plate 4 is in the same plane as the front face of the fixed mold 1, and the back face of the closing block 7 is in the same plane as the back face of the movable mold 2. After the fixed mold 1 is fitted with the movable mold 2, the movable mold 2 will no longer move. At this time, it is necessary to ensure that the hook 302 is connected to the fixing groove 701. The depth of the fixing groove 701 is the same as the length of the hook 302 on the protruding part of the front face of the front fixing plate 4. Therefore, when the closing block 7 is fitted with the front fixing plate 4, the hook 302 is connected and fixed to the fixing groove 701. A groove is provided on the front fixing plate 4. When the movable mold 2 is fitted with the fixed mold 1, the hook 302 is connected and fixed to the fixing groove 701. When the fixed mold 1 is separated from the movable mold 2, the hook 302 is disengaged from the fixing groove 701. The hook 302 needs to rotate during both fixing and disengagement. Therefore, the groove provided on the front fixing plate 4 is provided for the hook 302 to rotate. At the same time, the length of the groove provided on the front fixing plate 4 ensures that the hook 302 will not be hindered when rotating, so that the hook 302 can rotate smoothly.

[0037] In a preferred embodiment, when the connecting column 5 rotates, it drives the connecting shaft 502 to move in the rotating groove 5031. The rotation of the connecting column 5 drives the connecting rod 501 to change the fixed position. The connecting rod 501 is connected to the connecting shaft 502, and then drives the connecting shaft 502 to move. At this time, the rotating groove 5031 limits the direction and distance of movement of the connecting shaft 502, and the angle of rotation of the connecting column 5 causes the connecting tube 303 to move from the back of the moving groove 3041 to the front. When the connecting tube 303 is located on one side of the front of the moving groove 3041, it is in a fixed state. When the connecting shaft 502 drives the connecting tube 303 to move to one side of the front of the moving groove 3041, the hook 302 rotates upward and is fixed, so that the hook 302 is separated from the fixed groove 701. Therefore, the rotation angle of the connecting column 5 affects The connecting tube 303 is located at a moving position on the movable groove 3041. The two connecting columns 5 rotate in opposite directions but have the same rotation angle. The movable grooves 3041 fixed on both sides of the fixed mold 1 are bent in opposite directions. Therefore, the connecting column 5 rotates in opposite directions, causing the two connecting tubes 303 to move in opposite directions at the bending of the movable groove 3041, ensuring that both connecting tubes 303 can be fixed on the movable groove 3041. The connecting rod 501 is located on one side of the bottom of the connecting column 5. The change in the position of the connecting rod 501 is required to drive the change in the position of the connecting tube 303 on the movable groove 3041. However, when the connecting rod 501 is located in the middle of the bottom of the connecting column 5, the position of the connecting rod 501 will not change when the connecting column 5 rotates. Therefore, the connecting rod 501 needs to be fixed on one side of the bottom of the connecting column 5.

[0038] In a preferred embodiment, when the fixed column 3021 moves to the back of the sliding groove 3022, the connecting tube 303 moves to the side of the front of the moving groove 3041, and the fixed column 3021 is fixed on the fixed base 301 and will not move. Moving the fixed column 3021 to the back of the sliding groove 3022 requires the hook 302 to rotate, so that the sliding groove 3022 moves, and the hook 302 is connected to the connecting plate 305. Therefore, when the connecting plate 305 rotates, the hook 302 is driven to rotate, and the connecting plate 305 is connected to the connecting plate 305. The plate 305 is also connected to the connecting block 306, and the connecting block 306 is connected to the connecting tube 303. Therefore, the rotation of the connecting plate 305 drives the connecting tube 303 to move. The distance that the fixed column 3021 moves along the sliding groove 3022 is the same as the distance that the connecting tube 303 moves within the entire range of the moving groove 3041. The moving groove 3041 is an inverted L-shape. The connecting tube 303 moves a certain distance in the moving groove 3041 and is fixed at the bend. At this time, the connecting column 5 does not need to transmit kinetic energy, which is beneficial to saving energy.

[0039] In a preferred embodiment, the length of the rotating groove 5031 is the same as the radial length of the movable groove 3041. When the connecting shaft 502 moves in the rotating groove 5031, the connecting tube 303 moves radially in the movable groove 3041, and when the connecting shaft 502 moves to a range out of the rotating groove 5031, the connecting shaft 502 continues to drive the connecting tube 303 to move, but at this time the connecting tube 303 continues to move along the bend of the movable groove 3041 to fix the connecting tube 303.

[0040] In a preferred embodiment, the height of the back of the fixing groove 701 is two centimeters greater than the height of the groove on the front fixing plate 4. When the fixing column 3021 moves along the path of the sliding groove 3022, it drives the hook 302 to rotate. The range of rotation of the hook 302 is the height of the groove on the front fixing plate 4. When the hook 302 is located within the range of the fixing groove 701, the front length of the hook 302 is larger, so the space range required for rotation is larger. The height of the back of the fixing groove 701 allows the front of the hook 302 to rotate smoothly.

[0041] The working principle of the present invention is as follows: the control system controls the movable mold 2 to move toward the fixed mold 1, so that the front surface of the fixed mold 1 fits with the back surface of the movable mold 2, thereby fitting the extrusion block 6 with the extrusion groove 201. At this time, the front surface of the front fixed plate 4 fits with the back surface of the closing block 7, and the hook 302 is located in the fixed groove 701. The connecting column 5 is controlled to rotate and drive the hook 302 to rotate downward, so that the hook 302 and the fixed groove 701 are completely fitted. Then, the injection liquid is input into the extrusion groove 201 from the channel of the liquid guide pipe 104. After cooling and shaping, the movable mold 2 is controlled to move away from the fixed mold 1.

[0042] When the connecting rod 303 moves, the connecting rod 302 is moved to the left of the connecting rod 303 and the connecting rod 303 is moved to the right of the connecting rod 303. The movable sleeve is connected with a fixed column 3021, which is fixed to the fixed base 301 and will not move. When the connecting plate 305 rotates with the connecting pipe 303, the hook 302 rotates in the direction of the sliding groove 3022 during the rotation of the connecting plate 305. When the connecting column 5 rotates until the connecting shaft 502 is out of the rotating groove 5031, the connecting pipe 303 moves to the bending part of the movable groove 3041, and then the connecting column 5 continues to rotate, driving the connecting pipe 303 through the connecting shaft 502. 03 moves toward the bend of the movable groove 3041. When the connecting tube 303 fits with the edge of the bend of the movable groove 3041, the connecting column 5 stops rotating. At the same time, the connecting tube 303 is fixed in the movable groove 3041. At this time, the connecting tube 303 drives the connecting plate 305 to be fixed. After the connecting plate 305 is fixed, the hook 302 also stops moving. At this time, the fixed column 3021 fits with the back of the sliding groove 3022, so that the hook 302 is separated from the fixed groove 701, thereby separating the movable mold 2 from the fixed mold 1.

[0043] Then, the lower rotating rod 101 and the upper rotating rod 102 are controlled to rotate, so that the powerful fan 103 moves to the front of the extrusion block 6, which is also behind the extrusion groove 201 at this time. The control system transmits power to the powerful fan 103, so that the powerful fan 103 outputs strong wind force to the extrusion groove 201, promotes the circulation of air around the movable mold 2, and further reduces the temperature of the extrusion groove 201 and the headlight model, preventing the headlight model from sticking to the extrusion groove 201, and then removes the completed headlight model.
