Description

Technical Field

[0001] The utility model relates to the technical field of pressing tooling for automobile parts, in particular to an intelligent constant temperature pressing tooling for all-plastic door cover products. Background Art

[0002] In the prior art, there are mainly three pressing schemes for all-plastic door cover products: 1. The pressing tooling of some all-plastic door cover products relies on the gravity of the tooling itself and the pressing force of the pressing machine to ensure the stable connection between the inner and outer panels of the all-plastic door cover products through long-term pressing. This pressing scheme takes a long time and has low production efficiency; 2. The pressing tooling of another part of all-plastic door cover products uses hot air heating to indirectly heat the glue, which shortens the pressing time, but this scheme cannot control the temperature of each glue-coating area. Due to the low heat transfer efficiency, the product is prone to uneven heating and deformation, and some parts of the product are prone to debonding; 3. There are also some all-plastic door cover products that use infrared heating tubes to heat the inner plate of the product, and use sensors to detect the temperature of each area of ​​the product in real time. Since the infrared heating tubes of this solution are scattered and the heating sources are far apart, it is easy for the outer plate to fit in the heating area. The glue bonding effect is good. Since some areas are far away from the heating source and the heat transfer efficiency of plastic products is relatively low, the temperature difference between different areas of the same product is too large, and the product is very easy to deform, resulting in a step difference between the product and the counterpart, too large a difference in parallelism, and wavy outer plate surface differences, resulting in poor appearance perception. Therefore, it is necessary to design a tool that can solve the problem of local deformation caused by uneven heating of the product and shorten the product pressing time. Utility Model Content

[0003] The purpose of the utility model is to provide a constant temperature pressing tool based on the use conditions and current status of the existing all-plastic door cover pressing tool, so as to solve the problems in the prior art of too long pressing time of inner and outer panels of automobile all-plastic door covers, local deformation of products caused by uneven heating of products, and local waving of outer panels of products due to excessive difference in surface difference and parallelism, thereby improving the perceived quality of product appearance and effectively saving pressing time.

[0004] The technical solution of the utility model is: to provide an intelligent constant temperature pressing tool for all-plastic door cover products, which is used to press the target product, and the pressing tool is connected to the ECU module and the blower respectively, and the pressing tool includes: an upper mold, a lower mold and an ultra-high temperature heating belt;

[0005] The target product is arranged between the upper mold and the lower mold, the ultra-high temperature heating belt is installed on the lower mold, the ultra-high temperature heating belt contacts the target product to provide heat for it, and the lower mold is provided with heat dissipation ventilation grooves, the heat dissipation ventilation grooves are arranged below the ultra-high temperature heating belt and are connected to the ultra-high temperature heating belt.

[0006] Furthermore, a plurality of heating belt installation grooves are arranged on the lower mold, and the plurality of heating belt installation grooves are evenly distributed at positions on the lower mold corresponding to the heating areas of the target product.

[0007] Furthermore, the heat dissipation ventilation groove is arranged in the middle position below the ultra-high temperature heating belt, and is connected to all the heating belt installation grooves along the distribution direction of the heating belt installation grooves to dissipate heat for the target product. The heat dissipation ventilation groove is also cross-arranged in the middle position of the annular area formed by the heating belt installation grooves.

[0008] Furthermore, a plurality of blower air outlets are arranged on the lower tire, and the plurality of blower air outlets are evenly distributed in the heat dissipation and ventilation slots, and one end of the blower air outlet away from the heat dissipation and ventilation slots corresponds to the blower exhaust port.

[0009] Furthermore, the ultra-high temperature heating belt is bonded to the heating belt installation groove, and the ultra-high temperature heating belt contacts the heating area of ​​the target product to provide heat therefor.

[0010] Furthermore, the pressing tool also includes a temperature sensor. A temperature detection site is set on the lower mold near the ultra-high temperature heating belt, and a probe of the temperature sensor is installed on the temperature detection site.

[0011] Furthermore, the temperature sensor and the ultra-high temperature heating belt are respectively connected to the ECU module for communication, and the ECU module is also connected to the blower for communication.

[0012] Furthermore, a first temperature threshold and a second temperature threshold are set inside the ECU module, and the ECU module receives a temperature signal sent by the temperature sensor. When the detected temperature reaches the first temperature threshold, the ECU module switches the power supply voltage of the ultra-high temperature heating belt to a low voltage, otherwise it switches to a high voltage;

[0013] When switching to the low voltage state, when the detected temperature reaches the second temperature threshold, the ECU module sends an electrical signal to the blower to increase the wind speed, and the blower is adjusted to a high wind speed. Otherwise, it sends an electrical signal to reduce the wind speed to the blower, and the blower is adjusted to a low wind speed.

[0014] Furthermore, the heating belt installation grooves are evenly distributed on the lower tire at the same intervals, and the distance between two adjacent heating belt installation grooves is 30 mm.

[0015] Furthermore, the pressing tool also includes an upper jig mounting plate and a lower jig mounting plate, the upper jig is mounted on the upper jig mounting plate, and the lower jig is mounted on the lower jig mounting plate.

[0016] The beneficial effects of the utility model are:

[0017] First, the technical solution in the utility model sets a heating belt installation groove at a position corresponding to the product heating area on the lower mold, and the heating belt installation grooves are evenly spaced and densely distributed, so that after the ultra-high temperature heating belt is installed, it can provide heat to the product's heating area more evenly, quickly and directly, and a heat dissipation ventilation groove is set below the position where the ultra-high temperature heating belt is installed on the lower mold, the heat dissipation ventilation groove is connected to the ultra-high temperature heating belt, and the blower air outlet is evenly arranged in the heat dissipation ventilation groove. The blower air outlet is used to introduce the airflow into the heat dissipation ventilation groove. The heat dissipation ventilation groove transmits constant temperature airflow between each ultra-high temperature heating belt, and the excess heat generated by each ultra-high temperature heating belt is taken away by the airflow, and the excess heat is compensated to other areas with lower temperatures, so that the heating area on the product is heated more evenly.

[0018] In the prior art, large-area hot air heating and infrared heating tube heating are commonly used. Due to the low heat transfer efficiency of the plastic parts used in the production of all-plastic door covers, large-area hot air heating cannot directly and quickly heat the product area to be heated, and the energy consumption is high, which does not meet the needs of energy conservation and emission reduction. When infrared heating tubes are used for heating, the heating source is unevenly distributed, resulting in uneven local heating of the product, which is easy to deform the product locally, and ultimately leads to product size deviation and perceived quality deterioration. Compared with the prior art, the technical solution in the utility model can heat the product area to be heated more directly and quickly, wherein the design of the heat dissipation ventilation slot can make the product heated evenly, so that the temperature of each glue coating area of ​​the product is kept consistent, avoiding the problem of local deformation, size deviation, and perceived quality deterioration of the product caused by excessively high or low local temperature, and the technical solution in the utility model uses ultra-high temperature heating belts for local heating, and uses excess heat to maintain the product temperature, which greatly reduces energy consumption and better meets the needs of energy conservation and emission reduction.

[0019] Second, the technical solution in the utility model sets multiple temperature detection sites on the lower mold, uses temperature sensors to detect the temperature of each point of the product, and can select the heat generation of the ultra-high temperature heating belt and the wind speed of the blower according to the temperature during the pressing of the product. The technical solution in the utility model can quickly and evenly heat the product by heating with the ultra-high temperature heating belt and flowing gas in the heat dissipation ventilation grooves, and can quickly and evenly cool the product by reducing the heat generation of the ultra-high temperature heating belt and increasing the speed of the flowing gas in the heat dissipation ventilation grooves, effectively reducing the pressing time of the product. Compared with the methods in the prior art, the technical solution in the utility model improves the heating and cooling methods of the existing pressing tooling for all-plastic door cover products, and can provide a constant temperature condition for the product.

DETAILED DESCRIPTION

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are elaborated to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 4As shown, this embodiment provides an intelligent constant temperature pressing tool for all-plastic door cover products, which is used to press the target product to be pressed, including: an upper mold 1, a lower mold 2, an upper mold mounting plate 3, a lower mold mounting plate 4, an ultra-high temperature heating belt 5 and a temperature sensor 6.

[0032] like Figure 1 As shown, the upper jig 1 is installed on the upper jig mounting plate 3, the lower jig 2 is installed on the lower jig mounting plate 4, the product to be pressed is set between the upper jig 1 and the lower jig 2 for pressing, the lower jig 2 is provided with a heating belt mounting groove 21, the ultra-high temperature heating belt 5 is fixed on the lower jig 2 by connecting with the heating belt mounting groove 21, the ultra-high temperature heating belt 5 is in contact with the target product to provide heat for it, and the temperature sensor 6 is installed on the lower jig 2, and its probe is set on the lower jig 2 near the ultra-high temperature heating belt 5.

[0033] The upper jig 1 and the lower jig 2 cooperate with each other to press the product. The shape and size of the upper jig 1 match the requirements of the product to be pressed, and is used to apply pressure and provide a corresponding shape and structure. The lower jig 2 corresponds to the upper jig 1, and its shape and size match the requirements of the product to be pressed, and is used to support the workpiece and provide a corresponding shape and structure.

[0034] The upper jig mounting plate 3 is used to connect the upper jig 1 and fix it to the upper part of the laminating machine, and the lower jig mounting plate 4 is used to connect the lower jig 2 and fix it to the lower part of the laminating machine.

[0035] like Figure 3 and Figure 4 As shown, the product to be pressed includes an outer plate 7 and an inner plate 8. The inner side of the inner plate 8 is used to set a glue groove 81 at the position for pressing with the outer plate 7. The inner side of the inner plate 8 is the side close to the outer plate 7. The outer side of the inner plate 8 and the position corresponding to the glue groove are the heating area. The outer side of the inner plate 8 is the side away from the outer plate 7. The heating area corresponds to the position of the heating belt installation groove 21 on the lower mold 2, so that after the high-temperature heating belt 5 is installed on the heating belt installation groove 21, it can better heat the heating area. The product to be pressed also includes inner and outer plate structural adhesive 82, which is set in the glue groove 81 and is located between the outer plate 7 and the inner plate 8.

[0036] like Figure 2 and Figure 5 As shown, a heating belt mounting groove 21 , a heat dissipation ventilation groove 22 and a blower air outlet duct 23 are provided on the lower mold 2 .

[0037] The heating belt installation groove 21 is used to install the ultra-high temperature heating belt 5. The heating belt installation groove 21 includes a plurality of individuals and is evenly distributed at positions corresponding to the heating area on the lower mold 2. Any two adjacent heating belt installation grooves 21 are spaced 30 mm apart.

[0038] The heat dissipation ventilation slot 22 is used to transmit the constant temperature airflow blown by the blower during the pressing process, so that the heating area on the product maintains a constant temperature state. The heat dissipation ventilation slot 22 is set in the middle position below the ultra-high temperature heating belt 5, and is connected to all the heating belt installation slots 21 in sequence along the distribution direction of the heating belt installation slots 21. The heat dissipation ventilation slot 22 is also cross-set in the middle position of the annular area formed by the heating belt installation slots 21. Specifically, Figure 2 As shown, in this embodiment, the heating area on the product to be pressed includes a strip heating area and an annular heating area. At the position of the lower mold 2 corresponding to the strip heating area, the heat dissipation ventilation groove 22 is set in the middle of the heating belt mounting groove 21 along the distribution direction of the heating belt mounting groove 21. At the position of the lower mold 2 corresponding to the annular heating area, the heat dissipation ventilation groove 22 is set in the middle of the heating belt mounting groove 21 along the distribution direction of the heating belt mounting groove 21. In addition, the heat dissipation ventilation groove 22 is cross-arranged in the middle of the area with the annularly distributed tropical mounting groove 21 as the edge.

[0039] The lower mold 2 includes a plurality of blower air outlet ducts 23, and the plurality of blower air outlet ducts 23 are evenly arranged in the heat dissipation ventilation groove 22 at the same interval. During the pressing process, a blower is arranged on the side of the blower air outlet duct 23 away from the heat dissipation ventilation groove 22, and one end of the blower air outlet duct 23 away from the heat dissipation ventilation groove 22 corresponds to the blower exhaust port, which is used to introduce the airflow blown by the blower into the heat dissipation ventilation groove 22.

[0040] The ultra-high temperature heating belt 5 is used to heat the heating area on the product during the lamination process. The ultra-high temperature heating belt 5 includes a plurality of individuals, the number of which is the same as the number of the heating belt installation slots 21. The ultra-high temperature heating belt 5 is glued to the heating belt installation slots 21, and the interval between any two adjacent ultra-high temperature heating belts 5 is 30 mm. In this embodiment, in order to make the product to be pressed evenly heated and improve the product pressing efficiency, a large number of ultra-high temperature heating belts 5 are arranged and distributed on the pressed lower mold 2. The ultra-high temperature heating belts 5 are only spaced 30 mm apart. The shortened interval ensures that the product is heated evenly from a structural point of view.

[0041] Each ultra-high temperature heating belt 5 is connected through the heat dissipation ventilation groove 22, and the constant temperature airflow blown by the blower enters the heat dissipation ventilation groove 22 through the blower outlet 23. During the pressing process, the heat dissipation ventilation groove 22 transfers the constant temperature airflow blown by the blower between each ultra-high temperature heating belt 5, and takes away the excess heat generated by each ultra-high temperature heating belt 5 through the airflow, so that the heating area on the product remains at a constant temperature. The setting of the heat dissipation ventilation groove 22 can not only reduce the temperature of the area on the product that contacts the ultra-high temperature heating belt 5, but also compensate for the temperature of the area that does not contact the ultra-high temperature heating belt 5, so that the product is heated as evenly as possible, and the excess heat is discharged from the exhaust hole with the airflow, so as to maintain the temperature of the entire product during the pressing process.

[0042] A temperature detection site is set on the lower mold 2 near the ultra-high temperature heating belt 5, and a probe of the temperature sensor 6 is installed on the temperature detection site to detect the temperature of each point of the pressing position on the product.

[0043] The intelligent constant temperature pressing tooling for all-plastic door cover products is also connected to the ECU module (referring to an existing control unit), wherein the ECU module is connected to the temperature sensor 6 for receiving the temperature signal of the temperature sensor 6; the ECU module is connected to the ultra-high temperature heating belt 5 for increasing or decreasing the temperature of the ultra-high temperature heating belt 5; the ECU module is also connected to the blower for increasing or decreasing the wind speed of the blower.

[0044] The ECU module sets a first temperature threshold and a second temperature threshold inside, and the ECU module receives a temperature signal sent by the temperature sensor 6. When the detected temperature reaches the first temperature threshold, the ECU module switches the power supply voltage of the ultra-high temperature heating belt 5 to a low voltage state to reduce the temperature of the ultra-high temperature heating belt 5. When the detected temperature does not reach the first temperature threshold, the power supply voltage of the ultra-high temperature heating belt 5 is switched to a high voltage state to increase the temperature of the ultra-high temperature heating belt 5. After switching to the low voltage state, when the detected temperature reaches the second temperature threshold, the ECU module sends an electrical signal to the blower to increase the wind speed, and the blower is adjusted to a high wind speed to increase the speed of the airflow in the heat dissipation ventilation slot 22, and quickly reduce the temperature of the heating area on the product. When the detected temperature does not reach the second temperature threshold, the ECU module sends an electrical signal to the blower to reduce the wind speed, and the blower is adjusted to a low wind speed. If the current wind speed of the blower corresponds to the electrical signal sent by the ECU module, the original wind speed remains unchanged. In this embodiment, the above-mentioned detected temperature reaches the first temperature threshold, where reaching means greater than or equal to, that is, the detected temperature is greater than or equal to the first temperature threshold; the above-mentioned detected temperature does not reach the first temperature threshold, where not reaching means less than.

[0045] In this embodiment, the working principle of an intelligent constant temperature pressing tool for all-plastic door cover products is as follows:

[0046] Assemble the pressing tooling, glue the ultra-high temperature heating belt 5 into the heating belt mounting groove 21 of the lower mold 2 by glue; set the blower on the side of the blower air outlet 23 away from the heat dissipation ventilation groove 22, and adjust the exhaust port of the blower to a position facing the blower air outlet 23; install the probe of the temperature sensor 6 at the selected temperature detection position on the lower mold 2; connect the ultra-high temperature heating belt 5, the temperature sensor 6 and the blower to the ECU module respectively.

[0047] Start the pressing machine to start the pressing process, apply the inner and outer panel structural adhesive 82 in the glue coating groove 81 of the inner panel 8 of the product to be pressed, align and dock the outer panel 7 and the inner panel 8 of the product to be pressed, and place them between the upper mold 1 and the lower mold 2 for pressing, use the ultra-high temperature heating belt 5 to heat the pressing position, turn on the blower, and during the pressing process, the constant temperature airflow blown out by the blower enters the heat dissipation ventilation groove 22 through the blower air outlet 23, and the constant temperature airflow flows along the heat dissipation ventilation groove 22 between each ultra-high temperature heating belt 5, taking away the residual heat in the area of ​​the product that contacts the ultra-high temperature heating belt 5, and compensating it to the area that does not contact the ultra-high temperature heating belt 5, so that the product is heated as evenly as possible. The temperature sensor 6 is used to detect the temperature of the selected location in real time and send a temperature signal to the ECU module. When the detected temperature reaches the first temperature threshold, the ECU module switches the power supply voltage of the ultra-high temperature heating belt 5 to a low voltage state to reduce the temperature of the ultra-high temperature heating belt 5, otherwise it switches to a high voltage state to increase the temperature of the ultra-high temperature heating belt 5; after switching to the low voltage state, when the detected temperature reaches the second temperature threshold, the ECU module sends an electrical signal to the blower to increase the wind speed, and the blower is adjusted to a high wind speed to increase the speed of the airflow in the heat dissipation ventilation slot 22, and quickly reduce the temperature of the heating area on the product, otherwise the blower is adjusted to a low wind speed so that the heating area on the product remains in a constant temperature state to maintain the temperature of the entire product during the pressing process.

For example, "connect" can be a fixed connection, a detachable connection, or an integral connection; "connect" can be a direct connection or an indirect connection through an intermediate medium.
