Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive dashboards, specifically to an automotive dashboard molding die with an anti-misalignment structure. Background Technology
[0002] The automotive dashboard mainly consists of instruments, steering wheel, dashboard housing, dashboard frame, and dashboard wiring harness. Automotive dashboards typically have complex shapes and dimensions, integrating various instrument panels, buttons, displays, and other components. Molding molds can precisely replicate these complex shapes and dimensions, ensuring a perfect match between the dashboard and other vehicle components. The molding molds for automotive dashboards are usually selected based on the dashboard's material and molding process. Common mold types include injection molds, slush molds, and vacuum forming molds. These molds are used to produce hard-surface dashboards and are characterized by structural stability and high production efficiency.
[0003] A search revealed an automotive dashboard molding die with publication number CN212266544U. Specifically, the die includes a lower mold layer with a molding cavity inside. An upper mold layer is connected to the top of the lower mold layer. A hot runner is installed inside the upper mold layer and connected to the molding cavity. A support frame is fixed to the top of the molding cavity, and a cylinder is fixed to the top of the support frame. A hot flow valve needle is connected to the bottom of the cylinder, and a buffer mechanism is installed inside the hot flow valve needle. A stripping mechanism is installed inside the lower mold layer, and a vibration mechanism is installed at the bottom of the lower mold layer. In this invention, a servo motor drives a gear to rotate. The rotating gear causes a push rod connected to one side to move up and down in the through-slot of the lower mold layer, moving a support plate up and down within the molding cavity. This allows the molding die to be automatically ejected from the molding cavity, performing a demolding operation, thus changing the previous manual demolding method and improving production efficiency.
[0004] In the use of existing automotive dashboard molding dies, due to the high precision required in the production of automotive dashboards, the lack of an anti-misalignment structure during the mold closing process can lead to misalignment. Misalignment can result in appearance defects such as gaps and unevenness on the surface of the molded dashboard. Furthermore, the automotive dashboard molding die in the aforementioned comparative case also lacks an anti-misalignment structure. Over time, misalignment of the die will cause production interruptions, requiring machine downtime for adjustment and maintenance. This will directly affect production efficiency and increase the scrap rate.
[0005] Therefore, it is necessary to invent a car dashboard molding die with an anti-misalignment structure to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a molding die for an automotive dashboard with an anti-misalignment structure. This structure is achieved through an external locking buckle, positioning holes, positioning pins, an external anti-misalignment slot, an external anti-misalignment insert, a connecting plate, and an external locking strip. The positioning pins and positioning holes precisely engage to ensure initial positioning of the die during mold closing, reducing the risk of misalignment. After mold closing, the external anti-misalignment insert, inserted from the side, further reinforces the die's positioning, preventing misalignment during injection molding due to uneven force or vibration. Finally, the upper and lower molds are tightly locked together to form a stable whole, further preventing misalignment. This design significantly improves the performance of automotive dashboard molding over long-term use. The goal is to improve the precision, stability, and service life of the instrument panel molding die, while also enhancing production efficiency, product quality, and reducing scrap rates. This addresses the issue in existing automotive instrument panel molding dies where, due to the high precision required for instrument panel production, the lack of an anti-misalignment structure during the mold closing process can lead to misalignment. Misalignment results in surface defects such as gaps and unevenness on the finished instrument panel. Furthermore, the aforementioned comparative case also lacks an anti-misalignment structure in its instrument panel molding die. Over time, misalignment can cause production interruptions, requiring downtime for adjustments and repairs, directly impacting production efficiency and increasing scrap rates.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a molding die for an automotive dashboard with an anti-misalignment structure, comprising a molding die base for supporting the main body used for molding the automotive dashboard;
[0008] The lower forming mold is located above the forming mold base and is used for forming automotive dashboards. The lower forming mold has an inner forming groove inside and an inner sealing groove on the top. An external locking buckle is fixedly installed on the outside of the lower forming mold. A positioning hole is provided on one side of the inner forming groove of the lower forming mold. A positioning pin is movably connected inside the positioning hole, and an upper forming mold is fixedly installed at one end of the positioning pin.
[0009] An inner sealing ring is set inside the upper mold to improve the sealing performance after mold closing. An injection molding port is fixedly installed above the upper mold. An external anti-misalignment slot is provided on the outside of the lower mold. An external anti-misalignment insert is movably connected inside the external anti-misalignment slot. A connecting plate is fixedly installed at one end of the external anti-misalignment insert. Fastening bolts pass through the outside of the connecting plate.
[0010] An outer locking strip is set outside the upper mold to enhance the locking force after mold closing. An inner groove is provided on one side of the outer locking strip, and a telescopic spring is provided inside the inner groove. A locking block is fixedly installed at one end of the telescopic spring.
[0011] Preferably, the outer side of the molding die base is provided with an installation groove, and a positioning bolt is movably connected inside the installation groove.
[0012] Preferably, the mold base is provided with a telescopic cylinder, one end of which is fixedly installed with an ejector plate, and a demolding pin is fixedly installed above the ejector plate.
[0013] Preferably, the positioning post fixedly installed at the bottom of the upper forming mold is engaged with the positioning hole opened above the lower forming mold, and the positioning post and the positioning hole are used in conjunction.
[0014] Preferably, the connecting plate is fixedly connected to the external anti-misalignment insert, and the fastening bolts are symmetrically arranged around the central axis of the connecting plate.
[0015] Preferably, the locking block is movably connected to the outer locking strip, and the telescopic springs are evenly distributed on the inner groove.
[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0017] 1. This utility model is equipped with an external locking buckle, positioning hole, positioning post, external anti-misalignment slot, external anti-misalignment insert, connecting plate, and external locking strip. When using this automotive dashboard molding mold, the positioning post of the upper molding mold can be aligned with the positioning hole of the lower molding mold first. Then, after the mold is closed, the connecting plate is removed from both sides of the upper and lower molding molds. The external anti-misalignment insert of the connecting plate is inserted into the external anti-misalignment slot of the upper and lower molding molds. At the same time, when the mold is closed, the locking block outside the external locking strip can be pinched simultaneously, so that the locking block presses the telescopic spring, inserting the external locking strip into the external locking buckle. The telescopic spring drives the locking block to extend out from the notch, thus completing the locking of the upper and lower molding molds. The locking mechanism of the mold, when used in this way, gives the automotive dashboard molding mold an anti-misalignment structure. The positioning pins and positioning holes can fit precisely to ensure the initial positioning of the mold during the mold closing process, reducing the risk of misalignment. After the mold is closed, the external anti-misalignment inserts inserted from the side can further reinforce the positioning of the mold and prevent the mold from misaligning due to uneven force or vibration during the injection molding process. Finally, the upper and lower molds are tightly locked together to form a stable whole, further preventing misalignment. With long-term use, this can significantly improve the precision, stability and service life of the automotive dashboard molding mold, while also improving production efficiency and product quality and reducing the scrap rate.
[0018] 2. This utility model is equipped with a telescopic cylinder, an ejector plate, a demolding ejector pin, a lower forming mold, an inner sealing groove, an upper forming mold, and an inner sealing ring. When using this automotive dashboard molding mold, after the lower forming mold and the upper forming mold are closed, the inner sealing ring and the inner sealing groove fit together, which ensures the sealing performance of the molding mold, thereby improving the molding quality and precision of the product. This allows the automotive dashboard molding mold to adapt to pressure and temperature under different working environments. After the mold is opened, the telescopic cylinder can drive the ejector plate to rise, allowing the demolding ejector pin to extend from the bottom of the lower forming mold to demold the internal automotive dashboard. This simplifies the demolding and opening / closing process of the mold, reduces operational difficulty and time costs, and thus improves production efficiency. Attached Figure Description

Detailed Implementation
[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0028] This utility model provides, for example Figure 1-5 The car dashboard molding die shown includes a molding die base 1, which supports the main body for molding the car dashboard.
[0029] The lower forming mold 7 is set above the forming mold base 1 and is used for forming automotive dashboards. The lower forming mold 7 has an inner forming groove 8 inside and an inner sealing groove 9 on the top. An outer locking buckle 10 is fixedly installed on the outside of the lower forming mold 7. A positioning hole 11 is provided on one side of the inner forming groove 8 of the lower forming mold 7. A positioning pin 12 is movably connected inside the positioning hole 11. One end of the positioning pin 12 is fixedly installed with the upper forming mold 13.
[0030] An inner sealing ring 14 is set inside the upper molding mold 13 to improve the sealing performance after mold closing. An injection molding port 15 is fixedly installed above the upper molding mold 13. An external anti-misalignment slot 16 is opened on the outside of the lower molding mold 7. An external anti-misalignment plug 17 is movably connected inside the external anti-misalignment slot 16. A connecting plate 18 is fixedly installed at one end of the external anti-misalignment plug 17. A fastening bolt 19 passes through the outside of the connecting plate 18.
[0031] An outer locking strip 20 is set outside the upper mold 13 to enhance the locking force after mold closing. An inner groove 21 is provided on one side of the outer locking strip 20. A telescopic spring 22 is set inside the inner groove 21. A locking block 23 is fixedly installed at one end of the telescopic spring 22. After mold closing, the connecting plate 18 is taken out from both sides of the upper mold 13 and the lower mold 7. The outer anti-misalignment insert 17 of the connecting plate 18 is inserted into the outer anti-misalignment slot 16 of the upper mold 13 and the lower mold 7. At the same time, the locking block 23 outside the outer locking strip 20 can be pinched simultaneously when the mold is closed, so that the locking block 23 presses the telescopic spring 22 and inserts the outer locking strip 20 into the outer locking buckle 10. The telescopic spring 22 drives the locking block 23 to extend out from the notch. This completes the locking work of the upper mold 13 and the lower mold 7. With this combination, the automotive dashboard molding mold has an anti-misalignment structure.
[0032] like Figure 1 , Figure 2 and Figure 3As shown, the molding mold base 1 has an external mounting groove 2, and a positioning bolt 3 is movably connected inside the mounting groove 2. The mounting groove 2 and positioning bolt 3 on the outside of the molding mold base 1 facilitate the installation and use of the automotive dashboard molding mold in different environments and on different equipment. The molding mold base 1 has an internal telescopic cylinder 4, and an ejector plate 5 is fixedly installed at one end of the telescopic cylinder 4. A demolding ejector pin 6 is fixedly installed above the ejector plate 5. After the mold is opened, the telescopic cylinder 4 can drive the ejector plate 5 to rise, allowing the demolding ejector pin 6 to extend from the bottom of the lower molding mold 7 to demold the internal automotive dashboard. This simplifies the demolding and opening / closing process of the mold, reduces the difficulty of operation and time costs, and thus improves production efficiency.
[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the positioning pin 12 fixedly installed at the bottom of the upper mold 13 engages with the positioning hole 11 opened above the lower mold 7. The positioning pin 12 and the positioning hole 11 work together to ensure the precise positioning of the mold during the mold closing process and reduce the risk of misalignment. The connecting plate 18 is fixedly connected with the outer anti-misalignment insert 17. The fastening bolts 19 are symmetrically arranged around the central axis of the connecting plate 18. After the mold is closed, the outer anti-misalignment insert 17 inserted from the side can further reinforce the positioning of the mold and prevent the mold from misaligning due to uneven force or vibration during the injection molding process. The locking block 23 is movably connected with the outer locking strip 20. The telescopic springs 22 are evenly distributed on the inner groove 21. The outer locking strip 20 and the outer locking buckle 10 are tightly locked together, which can make the upper and lower molds form a stable whole and further prevent misalignment.
[0034] The working principle of this practical application is as follows: First, connect the external power supply and take out the automotive dashboard molding mold. Using the mounting slot 2 and positioning bolts 3 on the outside of the molding mold base 1, the automotive dashboard molding mold can be installed and used in different environments and on different equipment. After installation, align the positioning pins 12 of the upper molding mold 13 with the positioning holes 11 of the lower molding mold 7. Then, after closing the mold, remove the connecting plates 18 from both sides of the upper molding mold 13 and the lower molding mold 7. Insert the outer anti-misalignment inserts 17 of the connecting plates 18 into the outer anti-misalignment slots 16 of the upper molding mold 13 and the lower molding mold 7, and then tighten the fastening bolts 19. To enhance the stability of the connection, the locking block 23 outside the outer locking strip 20 can be simultaneously squeezed during mold closing, causing the locking block 23 to press against the telescopic spring 22, inserting the outer locking strip 20 into the outer locking buckle 10. Then, the telescopic spring 22 drives the locking block 23 to extend from the notch, thus completing the locking of the upper mold 13 and the lower mold 7. This gives the automotive dashboard molding die an anti-misalignment structure, allowing the positioning pin 12 and positioning hole 11 to precisely match, ensuring initial positioning of the mold during mold closing and reducing the risk of misalignment. After mold closing, the external anti-misalignment insert 17, inserted from the side, can further... The mold positioning is reinforced to prevent misalignment during injection molding due to uneven force or vibration. Finally, the upper and lower molds are tightly locked together to form a stable whole, further preventing misalignment. After this preparation is complete, external equipment can be activated to inject the molding material into the automotive dashboard molding mold through the injection port 15. During the molding process, the closing of the lower molding mold 7 and the upper molding mold 13 causes the inner sealing ring 14 to fit with the inner sealing groove 9, ensuring the sealing of the molding mold and thus improving the molding quality and precision of the product. The mold adapts to pressure and temperature under different working environments. After the mold is opened, the switch of the telescopic cylinder 4 can be turned on, and the telescopic cylinder 4 drives the ejector plate 5 to rise, allowing the ejector pin 6 to extend from the bottom of the lower mold 7 to demold the internal car dashboard. This simplifies the demolding and opening / closing process of the mold. Finally, after completing the installation and use of the entire car dashboard molding mold according to the above operations, the switch of the telescopic cylinder 4 is turned off. If it is not used for a long time, the external power supply can be cut off. In this way, the use of the car dashboard molding mold with anti-misalignment structure is completed.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
