Description

Technical Field

[0001] The present invention relates to the technical field of automotive interior part processing, and particularly to a cooling mold structure for injection molding of automotive interior parts. Background Art

[0002] Automotive interior parts mainly refer to automotive products used for internal modification of automobiles, covering all aspects inside the automobile. For example, automotive steering wheel covers, automotive seat cushions, automotive floor mats, automotive perfumes, automotive pendants, interior ornaments, storage boxes, etc. are all automotive interior products. Products such as automotive storage boxes or automotive seat cushion floor mats are generally processed by injection molding during the processing because they are all made of plastic materials. During the injection molding process, the necessary processing structure is the mold. Therefore, the important structure during the processing of automotive interior parts is the mold structure.

[0003] When traditional injection molds for automotive interior parts are in use, they are subjected to high temperature and high pressure, which may cause deformation of the injection molds for automotive interior parts during use. The deformation of the injection molds for automotive interior parts will affect the shape and dimensional accuracy of the products, and in severe cases, it may even cause the mold to be unable to be used normally.

[0004] Therefore, in order to avoid the above problems, a cooling mold structure for injection molding of automotive interior parts is needed. Summary of the Invention

[0011] Furthermore, the first cooling elbow pipe is tightly arranged inside the second cooling cavity, and both ends of the first cooling elbow pipe penetrate through the surface of the die and are respectively fixedly connected to the right surfaces of the upper and lower cooling shells.

A circulation mechanism for reciprocating flow is provided on the lower side of the inner wall of the lower cooling shell 8.

[0025] The circulation mechanism includes a push plate 801 movably installed on the lower side of the inner wall of the cooling shell 8. The push plate 801 can move under the suction or thrust generated by the contraction or extension of the corrugated hose 13, so as to better push the liquid in the cooling shell 8 completely into the cooling elbow structure. The push plate 801 is a rectangular plate made of rubber. On the opposite sides of the upper and lower cooling shells 8, a number of semiconductor refrigeration chips 802 for cooling are provided, and a heat-conducting aluminum sheet 803 for heat conduction is fixedly installed on the surface of the semiconductor refrigeration chip 802. Liquid guiding ports 804 for regulating the liquid are opened on the top surface of the upper cooling shell 8 and the right surface of the lower cooling shell 8, and sealing covers 805 for sealing are threadedly connected inside the liquid guiding ports 804.

[0026] Among them, the surfaces of a number of limiting cross bars 7 penetrate through the surface of the punch 2, and the right ends of a number of limiting cross bars 7 are fixedly connected to the surface of the die 3. The two cooling shells 8 are both rectangular shell structures and are symmetrically arranged up and down between the die 3 and the punch 2. The first cooling elbow 11 is tightly arranged inside the second cooling cavity 5, and the two ends of the first cooling elbow 11 penetrate through the surface of the die 3 and are fixedly connected to the right surfaces of the upper and lower cooling shells 8 respectively. The second cooling elbow 12 is tightly arranged inside the first cooling cavity 4, and the rear end of the second cooling elbow 12 penetrates through the rear side of the inner wall of the first cooling cavity 4 and extends to the back of the punch 2.

[0027] Specifically, the air supply elbow 14 is a Z-shaped elbow made of stainless steel. The surface of the air supply elbow 14 penetrates through the inside of the punch 2. The end of the air supply elbow 14 is fixedly connected to the end of the second cooling elbow 12 through a connecting pipe fitting 17. The surfaces of a number of corresponding heat-conducting aluminum sheets 803 penetrate through the surface of the cooling shell 8 and extend to the inside thereof, and the heat-conducting aluminum sheet 803 is a corrugated sheet structure with a thickness of five millimeters.

[0028] It should be noted that a top cavity 16 for pushing the product is provided on the left side of the first cooling cavity 4 inside the punch 2. A moving plate 1601 for moving is slidably installed on the inner wall of the top cavity 16. Mold ejector pins 1602 for moving are fixedly installed at the four corners on the right side of the moving plate 1601. A push plate 1603 for pushing is fixedly installed on the left side of the moving plate 1601. Two guide rods 1604 for limiting are embedded and installed through the left side inner wall of the top cavity 16 on the left side of the push plate 1603. Two springs 1606 for pushing are fixedly installed on the rod arms of the two guide rods 1604 through a slidably installed sliding plate 1605. A bidirectional screw 1608 for adjustment is commonly threadedly installed between the sliding plate 1605 and the fixed vertical plate 6 through a fixedly installed threaded sleeve 1607. A rotating block 1609 for rotation is fixedly installed at the center of the rod arm of the bidirectional screw 1608. The right sides of a number of mold ejector pins 1602 penetrate through the inside of the punch 2 and the first cooling cavity 4. The penetration effect of the mold ejector pins 1602 is the existing installation process of the mold ejector pins 1602. A number of mold ejector pins 1602 can cooperate well with other parts of the mold, and the influence on the product processing quality can be controlled within a small range. The designed positions of a number of mold ejector pins 1602 of this device are relatively compact and the number is large, which can optimize the product forming process and improve the product quality. These technologies are all mature installation technologies. The innovative structure of this application will not elaborate too much on the existing technologies. It extends to the surface of the punch 2, and a number of mold ejector pins 1602 are arranged in a staggered manner with the second cooling elbow 12. The left ends of the two guide rods 1604 are fixedly connected to the surface of the fixed vertical plate 6. The two springs 1606 are sleeved on the rod arms of the corresponding guide rods 1604, and the ends of the springs 1606 are fixedly connected to the surface of the push plate 1603.

[0029] The working principle of the above embodiment is as follows: When the device is in use, the female mold 3 is installed with the injection molding equipment. By the fitting of the punch 2 and the female mold 3, the effect of the device for producing automotive interior parts is ensured. During the process of the relative or opposite movement of the punch 2 and the female mold 3, the hydraulic rod 10 cooperates with the guide rod 1604 to perform stable pushing and pulling. And at this time, the corrugated hose 13 will be squeezed or stretched between the punch 2 and the fixed vertical plate 6; When the corrugated hose 13 is squeezed, it will blow air into the air supply elbow 14. When the corrugated hose 13 is stretched, it will suck air into the air supply elbow 14. Since the air supply elbow 14 is a rigid pipe structure, such cooperation with the piston block 15 can perform piston movement in the air supply elbow 14, ensuring the reciprocating flow effect of the liquid previously added in the first cooling elbow 11 and the second cooling elbow 12; Before the device is used, the liquid guide ports 804 on the two cooling shells 8 are opened, and the coolant is added through the liquid guide ports 804 on the upper cooling shell 8. When adding the coolant, the second cooling elbow 12 and the connecting pipe fitting 17 are in a disconnected state, which can ensure that the second cooling elbow 12 is filled with coolant, and the liquid guide port 804 of the lower cooling shell 8 is also in an open state, which can ensure that the coolant in the first cooling elbow 11 is also in a full state. When there is coolant flowing out at the position of the connecting pipe fitting 17 of the second cooling elbow 12, it means that the coolant filling of the second cooling elbow 12 is completed. When there is coolant flowing out of the lower cooling shell 8, at this time, the lower sealing cover 805 is closed and the coolant is continuously added to the upper cooling shell 8 until there is coolant overflowing from the upper cooling shell 8, which means that the coolant filling of the first cooling elbow 11 is completed. Then the upper sealing cover 805 is closed. When adding the coolant, the female die 3 and the male die 2 are in a closed state; Through the air supply and suction effects of the corrugated hose 13, it can ensure the reciprocating flow of the liquid in the first cooling elbow 11 and the second cooling elbow 12. When the corrugated hose 13 is compressed, the air supply elbow 14 is in a blowing state, and the gas will pump the liquid in the second cooling elbow 12 to the upper cooling shell 8, and the coolant in the upper cooling shell 8 will flow into the first cooling elbow 11. At this time, the liquid in the first cooling elbow 11 will flow into the lower cooling shell 8. This is a liquid conversion between the first cooling elbow 11 and the second cooling elbow 12. When the corrugated hose 13 is stretched, a suction force will be generated in the air supply elbow 14. In this way, the liquid in the lower cooling shell 8 will flow into the first cooling elbow 11. In this way, the coolant cooled in the lower cooling shell 8 will flow into the first cooling elbow 11, which can ensure that the female die 3 where the first cooling elbow 11 is located is cooled. At this time, the coolant that has been heated in the first cooling elbow 11 will flow back into the upper cooling shell 8, and the cooled liquid in the upper cooling shell 8 will transport the original liquid in the second cooling elbow 12 in the direction of the air supply elbow 14, thereby ensuring that the male die 2 where the second cooling elbow 12 is located is cooled, ensuring the cooling effect of the overall device. The corrugated hose 13 in this device is sealed in the cooling pipeline structure, so the generated thrust will almost entirely drive the liquid flow in the cooling elbow. When the corrugated hose 13 contracts, its internal space becomes smaller, which will generate pressure on the internal gas, increasing the gas pressure. Therefore, the increased pressure in the corrugated hose 13 will be transmitted to the liquid in the cooling elbow structure through the liquid connected to the corrugated hose 13, thereby realizing the liquid flow in the cooling elbow. A part of the second cooling elbow 12 in this device is connected to the cooling shell 8 by a hose, which can ensure that during the movement of the male die 2, it will not affect the liquid transmission effect of the second cooling elbow 12 and can ensure the normal cooling effect of the overall device; Since the spring 1606 is fixedly connected to the sliding plate 1605, when the distance between the two threaded sleeves 1607 is adjusted by rotating the bidirectional screw 1608, the sliding plate 1605 can drive the spring 1606 to move. The moving spring 1606 can ensure that the contact time of the push plate 1603 is adjustable. As the spring 1606 is stretched, the contact time of the relative push plate 1603 being pushed out becomes longer, thereby increasing the residence time of the coolant in the punch 2 and the die 3 and enhancing the cooling effect of the die 3 and the punch 2. Here, the push plate 1603 and the guide rod 1604 are connected in an embedded manner, that is, the guide rod 1604 can slide within the push plate 1603. Since the rotation of the bidirectional screw 1608 can adjust the distance between the two threaded sleeves 1607, if the distance between the threaded sleeves 1607 decreases, the spring 1606 is not restricted by extrusion. Thus, the spring 1606 will be stretched because it is not extruded by the sliding plate 1605. When the fixed vertical plate 6 drives the sliding plate 1605 to move towards the spring 1606, the spring 1606 will first be extruded to its original contracted amount, and then the elastic force of the spring 1606 can be used to push the push plate 1603 to move. After the fixed vertical plate 6 has moved for a period of time, the push plate 1603 will start to move, ensuring that the contact time with the push plate 1603 becomes longer. Consequently, the push plate 1603 can drive the mold ejector pin 1602 to push the product relatively slowly, guaranteeing that the pushing time of the push plate 1603 is adjusted to be longer. To shorten the pushing time of the push plate 1603, the above structure operates in the opposite manner, with the spring 1606 being pre - stressed. This prestress can be achieved by adjusting the distance between the two threaded sleeves 1607 through the rotation of the bidirectional screw 1608. In this way, when the fixed vertical plate 6 moves, it will directly drive the spring 1606 to push the push plate 1603, enabling the fixed vertical plate 6 to move and the mold ejector pin 1602 to push the product, thereby shortening the relative pushing time of the push plate 1603. During the pushing process, the initial pushing position of the fixed vertical plate 6 is set to be the same.

[0030] The installation methods, connection methods, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve their beneficial effects can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can realize the control of the electrical components through simple programming, and the existing publicly disclosed power connection technologies also belong to the common knowledge in this field. Therefore, the specific structural composition and working principle are not elaborated in detail in this embodiment.
