Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a combined ejection and core-pulling mechanism for automotive lights. Background Technology

[0002] Due to the rapid development of plastics, plastic products have penetrated into all walks of life. In the design of plastic parts, due to the need to consider the use and installation requirements of the products, the products often have some special structures. For example, in the production mold of car headlight covers, the side core pulling is particularly difficult due to the many curved surfaces in the shape. The ejector core pulling structure can easily damage the smooth surface of the headlight cover. Therefore, we have specially designed a combined ejector core pulling mechanism for car headlights. Utility Model Content

[0005] The mold includes an upper mold body and a lower mold body. The upper mold body is provided with a sprue, and the lower mold body is provided with an installation groove.

[0006] The sub-mold is detachably mounted on the mounting slot. The sub-mold has a movable core with a cavity formed inside.

[0007] The pneumatic core-pulling assembly is located inside the cavity, and an air passage is provided on the upper end face of the movable core.

[0008] The lower mold body has a through groove on its side wall, and a support plate is installed inside the through groove, which abuts against the lower mold body.

[0009] In the above technical solution, the sub-model further includes:

[0010] A fixing plate is installed in the mounting slot.

[0011] The main body is connected to the fixed plate, and air passages are formed on the upper parting surface of the main body;

[0012] End cap, the end cap is located at the bottom of the body;

[0013] The cavity is formed within the body and becomes a closed chamber after the end cap is connected to the body.

[0014] The pneumatic core-pulling assembly is located on the end cap and introduces gas through the air channel to the mating surface between the molded product and the body.

[0015] In the above technical solution, the pneumatic core-pulling assembly further includes:

[0016] An air pump is mounted on the end cap.

[0017] The first air tube is installed on the air pump and connected to the airway.

[0018] The second air tube is installed on the air pump and extends through the end cap to the outside.

[0019] Furthermore, the above technical solution also includes:

[0020] The auxiliary core-pulling assembly includes a filling block and a telescopic device, and an opening is provided on the side end face of the body parting surface. The filling block fits into the opening, and the telescopic device is provided on the end cap.

[0021] The air passage is located on the side wall of the opening and is exposed after the filling block detaches from the body parting surface.

[0022] Furthermore, the above technical solution also includes:

[0023] The fixed edge is set on the outer wall of the main body and is connected to the bottom of the fixed plate by bolts.

[0024] Furthermore, the above technical solution also includes:

[0039] Sub-mold 2 is detachably mounted on mounting groove 121. Sub-mold 2 is provided with a movable core, and the movable core has a cavity 221 formed inside.

[0040] The pneumatic core-pulling assembly 3 is disposed in the cavity 221, and the upper end face of the movable core is provided with an air passage 222.

[0041] The lower mold body 12 has a through groove 8 on its side wall, and a support plate 9 is installed in the through groove 8, which abuts against the lower mold body 12.

[0042] As can be seen from this embodiment, a vehicle headlight assembly ejection and core-pulling mechanism includes a mold 1, a sub-mold 2, and a pneumatic core-pulling component 3.

[0043] The mold 1 includes an upper mold body 11 and a lower mold body 12. The upper mold body 11 is formed with a parting cavity and a runner. The lower mold body 12 is formed with an installation groove 121. The sub-mold 2 is installed in the installation groove 121 and forms a parting surface that cooperates with the parting cavity. Furthermore, the sub-mold 2 has a cavity 221 inside and an air passage 222 is formed on the parting surface of the sub-mold 2. The pneumatic core-pulling assembly 3 is installed in the cavity 221. Furthermore, the lower mold body 12 has a through groove 8 formed on the side wall and a support plate 9 is installed in the through groove 8.

[0044] When in use, the staff first pulls the support plate 9 out of the through groove 8, thereby forming a gap between the sub-mold 2 and the mounting groove 121. Then, gas is injected into the mating surface between the parting surface of the sub-mold 2 and the product through the air channel 222, so that the sub-mold 2 can detach from the product and slide into the inside of the mounting groove 121, thereby achieving the purpose of core pulling and demolding.

[0045] Example 2:

[0046] This embodiment provides a combined headlight ejection and core-pulling mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] Sub-module 2 includes:

[0048] Fixing plate 21 is mounted on mounting groove 121;

[0049] The main body 22 is connected to the fixing plate 21, and an air passage 222 is formed on the upper parting surface of the main body 22.

[0050] End cap 23, which is located at the bottom of the body 22;

[0051] The cavity 221 is formed inside the body 22, and after the end cap 23 is connected to the body 22, a closed chamber is formed.

[0052] The pneumatic core-pulling assembly 3 is mounted on the end cap 23 and gas is introduced into the mating surface between the molded product and the body 22 through the air passage 222.

[0053] As can be seen from this embodiment, the sub-mold 2 includes a fixing plate 21, a body 22, and an end cap 23;

[0054] The fixing plate 21 is connected to the mounting groove 121 and abuts against the support plate 9. The air passage 222 is formed on the upper parting surface of the body 22. The body 22 is hollow inside. The end cap 23 is connected to the bottom of the body 22 and seals the body 22 to form a cavity 221.

[0055] Furthermore, the pneumatic core-pulling assembly 3 is mounted on the end cap 23 and is assembled with the air passage 222 when the end cap 23 is connected to the body 22;

[0056] The hollow interior of the main body 22 helps to reduce production costs. The end cap 23 facilitates the installation of the pneumatic core-pulling assembly 3. At the same time, after the fixing plate 21 is separated from the support plate 9, it is driven by the pneumatic core-pulling assembly 3 to move into the mounting groove 121.

[0057] Example 3:

[0058] This embodiment provides a combined headlight ejection and core-pulling mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] The pneumatic core-pulling assembly 3 includes:

[0060] Air pump 31 is mounted on end cap 23;

[0061] The first air pipe 32 is installed on the air pump 31 and connected to the airway 222.

[0062] The second air pipe 33 is installed on the air pump 31 and extends to the outside through the end cap 23.

[0063] As can be seen from this embodiment, the pneumatic core-pulling assembly 3 includes an air pump 31, a first air pipe 32, and a second air pipe 33;

[0064] An air pump 31 is installed on an end cap 23. A first air pipe 32 connects the air pump 31 and an air passage 222. A second air pipe 33 connects the air pump 31 and extends to the outside of the end cap 23 to communicate with an external air source.

[0065] During use, the air pump 31 supplies gas to the mating surface between the sub-mold 2 and the product through the first air pipe 32 and the second air pipe 33, thereby allowing the sub-mold 2 to detach.

[0066] Example 4:

[0067] This embodiment provides a combined headlight ejection and core-pulling mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] The auxiliary core-pulling assembly 4 includes a filling block 41 and a telescopic device 42. An opening 223 is provided on the side end face of the parting surface of the body 22. The filling block 41 is fitted on the opening 223, and the telescopic device 42 is provided on the end cap 23.

[0069] The air passage 222 is opened on the side wall of the opening 223 and is exposed after the filling block 41 is separated from the parting surface of the body 22.

[0070] As can be seen from this embodiment, the auxiliary core-pulling assembly 4 includes a filling block 41 and a telescopic device 42. Furthermore, an opening 223 with the same shape as the filling block 41 is provided on the end face of the upper parting surface of the body 22, and the port of the air passage 222 is located on the side wall of the opening 223.

[0071] The telescopic device 42 is installed on the end cap 23 and corresponds to the opening 223. The filling block 41 is connected to the telescopic device 42 and cooperates with the opening 223. In use, the telescopic device 42 controls the filling block 41 to move at the opening 223 and exposes or closes the air passage 222 port during the displacement process. This avoids the formation of burrs at the air passage 222 port without affecting the gas delivery and separation of the sub-mold 2, thereby reducing the processing steps.

[0072] Example 5:

[0073] This embodiment provides a combined headlight ejection and core-pulling mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0074] Fixed edge 5 is set on the outer wall of the main body 22 and is connected to the bottom surface of the fixed plate 21 by bolts.

[0075] As can be seen from this embodiment, a fixed edge 5 is provided on the outer wall of the main body 22 for connecting the fixed plate 21. Thus, after the fixed plate 21 is detached from the support plate 9, the main body 22 can move and change within the mounting groove 121 together with the fixed plate 21.

[0078] Limiting edge 6 is set on the lower port of opening 223 and restricts the movement of filling block 41.

[0079] As can be seen from this embodiment, by setting a limiting edge 6 at the lower port of the opening 223, the movement of the filling block 41 can be restricted, and the situation where the filling block 41 displaces too much and detaches from the opening 223 can be effectively avoided during the processing.

[0080] Example 7:

[0081] This embodiment provides a combined headlight ejection and core-pulling mechanism, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0082] The sealing gasket 7 is disposed on the limiting edge 6 and abuts against it when the filling block 41 moves down.

[0083] As can be seen from this embodiment, after the filling block 41 abuts against the sealing gasket 7, it seals the opening 223 port at the limiting edge 6, thereby preventing gas from flowing out and causing poor core pulling effect.

[0084] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
