However, the installation of the mesh fabric and the injection molding of the product are usually performed in two separate steps, resulting in lower production efficiency.

[0004] In view of the above-mentioned related technologies, this application provides a mold structure for the integrated molding of an automotive dashboard and a mesh fabric. Utility Model Content

[0005] In order to achieve integrated molding of mesh fabric and automotive dashboard, this application provides a mesh fabric insert fixing structure for automotive molds.

[0006] The technical solution for fixing a mesh insert in an automotive mold provided in this application is as follows:

[0007] A fixing structure for a mesh insert in an automotive mold includes a fixed base plate, a positioning seat disposed on the fixed base plate, a lower core mounted on the positioning seat, an upper core corresponding to the lower core, and an inclined ejector mechanism disposed on the lower core for product demolding. The inclined ejector mechanism is provided with a fixing component for positioning and installing the mesh. The fixing component includes a positioning spring pin slidably mounted on the inclined ejector mechanism and a positioning elastic element connected to the positioning spring pin. The end of the positioning spring pin extends out of the end face of the inclined ejector mechanism and corresponds to the upper core. The mesh has a spring pin hole that engages with the positioning spring pin.

[0008] By adopting the above technical solution, the setting of the fixing component can make the mesh cloth positioned and installed in the lower core, ensuring the stability of the fixing component in the lower core and ensuring the corresponding fit between the product and the mesh cloth during molding. At the same time, the setting of the elastic element allows the positioning spring pin to reset into the inclined ejector mechanism under the abutment action of the upper core after the upper and lower cores are closed.

[0009] Optionally, the positioning spring pin includes a positioning part, a limiting part and a mounting part in sequence along its length. The inclined top mechanism has a sliding through hole for mounting the positioning spring pin. The inclined top mechanism is provided with a pressure block at one end of the sliding through hole.

[0010] By adopting the above technical solution, the structural composition of the positioning spring pin and the arrangement of the elastic element are disclosed. The positioning spring pin includes a positioning part, a limiting part and an installation part. The positioning part and the mesh cloth are inserted and matched to achieve positioning. The two ends of the elastic element abut against the pressure block and the limiting part, so that the positioning spring pin as a whole can slide in the sliding through hole. The above-mentioned positioning spring pin and elastic element assembly method is simple and easy to assemble.

[0011] Optionally, the pressure block has a positioning through hole that communicates with the sliding through hole, and the mounting part is provided with a positioning post that cooperates with the positioning through hole.

[0012] By adopting the above technical solution, the cooperation between the positioning through hole and the positioning pin can limit the circumferential direction of the positioning spring pin, and at the same time improve the stability of the positioning spring pin in the sliding through hole.

[0013] Optionally, the inclined top mechanism is provided with a first positioning groove for mounting the pressure block, and a locking hole is provided on the bottom wall of the first positioning groove, and the pressure block is provided with a locking element that cooperates with the locking hole.

[0014] By adopting the above technical solution, the pressure block is positioned on the inclined top mechanism through the first positioning groove, and then the pressure block and the inclined top mechanism are fixed by the cooperation of the locking part and the locking hole. The installation method of the pressure block is relatively simple and the assembly efficiency is high.

[0015] Optionally, the inner wall of the sliding through hole is provided with a positioning surface for the limiting part to abut against.

[0016] By adopting the above technical solution, the positioning surface can limit the movement distance of the positioning pin and increase the stability of the positioning pin in the sliding through hole.

[0017] Optionally, the inclined top block is provided with two sets of fixing components, and a positioning protrusion is provided between the two sets of fixing components. The mesh fabric has positioning holes that cooperate with the positioning block for insertion.

[0018] By adopting the above technical solution, the setting of two sets of fixing components makes the positioning effect of the mesh fabric more ideal.

[0019] Optionally, the inclined top mechanism is further provided with a pre-installation component for insert nuts and product pre-installation. The pre-installation component includes a fixing insert fixed to the inclined top mechanism and a magnetic block for attracting the insert nuts.

[0020] By adopting the above technical solution and setting up pre-assembled components, the insert nut and the product can be integrally formed after the product is formed, which improves the production efficiency of the product. The insert nut is positioned by fixing the insert block and the stability of the insert nut is improved under the action of the magnetic block.

[0021] Optionally, the inclined top mechanism has a second positioning groove for mounting the fixed insert, the bottom wall of the second positioning groove is provided with a magnetic block groove for mounting the magnetic block, and the top of the fixed insert has an insertion groove communicating with the magnetic block groove.

[0022] By adopting the above technical solution, the installation method of the fixed insert and the inclined top mechanism, as well as the cooperation method of the insert nut and the pre-assembled component, are disclosed. When installing the fixed insert, the fixed insert is first positioned in the second positioning groove, and then fixed by bolts and other parts.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a fixing structure for mesh inserts in automotive molds.

[0036] Reference Figure 1 A fixing structure for a mesh insert in an automotive mold, used for integrated molding of a mesh fabric 7 and an automotive dashboard, includes a fixed base plate 1, a positioning seat 2, a lower core 3, and an inclined ejector mechanism 5. The positioning seat 2 includes four positioning plates 21 vertically fixed to the fixed base plate 1, forming a rectangular frame. An ejector mechanism, consistent with ejector mechanisms in existing molds, is installed within the rectangular frame. The lower core 3 is positioned on top of the positioning seat 2, and the ejector mechanism is used to eject the product formed on the lower core 3. The ejector mechanism also includes a hydraulic cylinder for driving the lower core 3 to rise and fall. An upper core 4 and a lower core 3 are correspondingly arranged, and after docking, they form a cavity for molding the product.

[0037] Reference Figure 2 and Figure 3 The inclined ejector mechanism 5 is part of the ejection mechanism, which includes an inclined ejector block 51 disposed at the bottom of the lower core 3 and a slider assembly 52 located below the lower core 3 and connected to the inclined ejector block 51.

[0038] The inclined top block 51 is provided with a fixing component 6 for installing the mesh fabric 7. The fixing component 6 includes a positioning spring pin 61 and an elastic element 62. The positioning spring pin 61 is slidably installed on the inclined top block 51, and the inclined top block 51 has a sliding through hole 511 through both end faces for the positioning spring pin 61 to be arranged. In this embodiment, the inclined top block 51 is provided with two sets of fixing components 6, and the two sets of fixing components 6 are spaced apart along the width direction of the mesh fabric 7. The inclined top block 51 is also provided with a positioning protrusion 512 between the two fixing components 6, and the positioning protrusion 512 is integrally formed with the inclined top block 51. The mesh fabric 7 has a spring pin hole 71 that cooperates with the positioning spring pin 61 and a positioning hole 72 that cooperates with the positioning protrusion 512.

[0039] The positioning spring pin 61 is arranged at an angle and includes, along its length, a positioning part 611, a limiting part 612, and a mounting part 613. The positioning part 611, limiting part 612, and mounting part 613 are all integrally formed, and the outer diameter of the limiting part 612 is larger than that of the positioning part 611 and the mounting part 613. The positioning part 611 is located at the angled top of the positioning spring pin 61 and is used for insertion and engagement with the mesh fabric 7. The end of the positioning part 611 is ball-shaped to facilitate the operator in positioning and mounting the mesh fabric 7 onto the surface of the angled top block 51.

[0040] The bottom of the inclined top block 51 has a first positioning groove 513 corresponding to the sliding through hole 511. A pressure block 53 is installed on the inclined top block 51 in the first positioning groove 513. The depth of the first positioning groove 513 is greater than the thickness of the pressure block 53. A locking hole 5131 is provided on the bottom wall of the first positioning groove 513. The locking hole 5131 is a threaded hole. The pressure block 53 has a through hole corresponding to the locking hole 5131, and a locking member 531 that cooperates with the locking hole 5131 is provided at the through hole. In this embodiment, the locking member 531 is a bolt. The first positioning groove 513 has locking holes 5131 on both sides of the sliding through hole 511 to improve the connection strength between the pressure block and the inclined top block 51.

[0041] The pressure block 53 has a positioning through hole 532 that penetrates both end faces and corresponds to the sliding through hole 511. The positioning through hole 532 is rectangular in shape, and its inner diameter is smaller than the overall outer diameter of the mounting part 613. The mounting part 613 has a positioning post 6131 that is adapted to be inserted into the positioning through hole 532. The positioning post 6131 and the positioning through hole 532 can limit the circumferential direction of the positioning spring pin 61. The elastic element 62 is a spring, which is sleeved on the outside of the mounting part 613, and its two ends abut against the limiting part 612 and the pressure block 53, respectively. The inner wall of the sliding through hole 511 also has a positioning surface 5111 for the abutment of one end face of the limiting part 612.

[0042] In the normal state of the spring, the positioning part 611 extends out of the top opening of the sliding through hole 511, that is, the positioning part 611 is exposed outside the inclined ejector block 51. When the upper and lower cores 3 are engaged in the mold, the positioning spring pin 61 is pressed into the sliding through hole 511 under the action of the upper core 4, at which time the elastic element 62 is in a compressed state. After the product cools and is formed, the upper core 4 moves away from the lower core 3, and the positioning spring pin 61 re-extends out of the sliding through hole 511 after the product is demolded.

[0043] Reference Figure 4 and Figure 5 In order to pre-install the insert nut 9 on the product, the inclined ejector block 51 is also provided with a pre-installation component 8. The pre-installation component 8 includes a fixing insert 81 and a magnetic block 82. The fixing insert 81 is a platinum copper insert, and multiple fixing inserts 81 are provided on the outer side of the inclined ejector block 51, which can quickly conduct heat out of the mold and improve the cooling and forming speed.

[0044] The top of the inclined top block 51 has a second positioning groove 514 for mounting the fixing insert 81, and the bottom wall of the second positioning groove 514 has a magnetic block groove 515 for mounting the magnetic block 82 and a mounting through hole 516 penetrating the bottom of the inclined top block 51. The mounting through hole 516 is a countersunk hole structure, and the inclined top block 51 is provided with a bolt for threaded fixing to the fixing insert 81 at the mounting through hole 516.

[0045] The bottom of the fixing insert 81 has a fixing screw hole 811 corresponding to the mounting through hole 516 and mating with the bolt. On both sides of the fixing screw hole 811, the fixing insert 81 has placement grooves 812 corresponding to the magnetic block groove 515. The inner diameters of the magnetic block groove 515 and the placement groove 812 are the same. A protective sleeve 83 is provided on the outer side of the magnetic block 82, the length of which is adapted to the groove formed by the magnetic block groove 515 and the placement groove 812. After the fixing insert 81 and the inclined top block 51 are fixed, the top surface of the magnetic block 82 abuts against the top wall of the placement groove 812.

[0046] The top of the fixing insert 81 has a insertion groove 813 that connects to the placement groove 812. The insert nut 9 is inserted into the insertion groove 813 and fixed under the action of the magnet 82.

[0047] The implementation principle of the mesh insert fixing structure for an automotive mold according to this application embodiment is as follows: The operator inserts the spring pin hole 71 of the mesh 7 into the corresponding positioning spring pin 61. The mesh 7 is simultaneously engaged with two positioning spring pins 61 and a positioning protrusion 512. Then, the insert nut 9 is inserted into the insertion groove 813, so that the insert nut 9 and the magnetic block 82 are attracted and fixed. After the upper and lower cores 3 are closed, the positioning spring pin 61 is retracted to the sliding through hole 511 under the action of the upper core 4. After the product is cooled and formed, the mesh 7 and the insert nut 9 are prefabricated on the product, realizing the integrated production of the mesh 7, the insert nut 9 and the automotive dashboard. The inclined ejector mechanism 5 can demold the product at an incline, so that the insert nut 9 can smoothly detach from the insertion groove 813, reducing the probability of the insert nut 9 being scratched.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
