Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a multi-point controllable injection structure and a plastic mold structure for an automotive center console. Background Technology

[0002] With the increasing application of artificial intelligence and other auxiliary functions in automobiles, the number of various functional components in the car center console is increasing. Due to space constraints, their arrangement is becoming more and more dense. The center console has a high density of positioning and limiting structures, resulting in a high defect rate during molding production. The main reason is that the center console is large in size and uneven in thickness, making it difficult to balance the flow rate of adhesive in different parts of the first mold cavity. This can easily lead to defects such as bubbles and flash. Moreover, removing the sprue can easily leave large marks on the product. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a multi-point controllable glue injection structure and a molding structure for automotive center console panels. This allows the flow rate of some glue injection channels to be adjusted individually, thereby ensuring that the glue is injected evenly from multiple points into the cavity during the glue injection process, reducing the molding defect rate. It also enables the synchronous movement of several cores on the outside of the cavity for subsequent operations. The structure is simple and effective.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A multi-point controllable injection structure is provided on the fixed mold of a plastic mold. The fixed mold includes a mold base, a sprue plate, a fixed mold plate, and a fixed mold core. A liquid storage tank is provided on the fixed mold base. A first cavity is formed at the end of the fixed mold core facing the moving mold. The multi-point controllable injection structure includes a first runner, several second runners, and several third runners.

[0006] The first flow channel is disposed on the nozzle plate and is connected to the liquid storage tank.

[0007] Several second flow channels are provided on the fixed template near the end of the sprue plate. One end of each second flow channel is connected to the first flow channel, and the other end extends away from the first flow channel. Several second flow channels are provided with flow-blocking blocks for controlling the flow rate of the adhesive liquid. Each flow-blocking block can be detachably fixed on the fixed template.

[0008] One end of each of the third flow channels is connected to the end of a second flow channel away from the first flow channel, and the other end of each flow channel passes through the fixed template and the fixed mold core in sequence and is connected to the first cavity.

[0009] As a further explanation of the above technical solution:

[0010] In the above technical solution, the number of the second flow channels is even, and they are arranged symmetrically on both sides of the first flow channel in pairs. At least one pair of the second flow channels is a straight flow channel, and at least one pair of the second flow channels is an arc-shaped flow channel.

[0011] In the above technical solution, each of the intercepting blocks is located on a straight flow channel.

[0012] In the above technical solution, each of the intercepting blocks can be detachably fixed on the fixed template, and has an intercepting channel adapted to and connected to a second flow channel. The fixed template is provided with a plurality of sliding grooves, each of which can accommodate one of the intercepting blocks, and the length of each of the sliding grooves is greater than the length of the intercepting block.

[0013] In the above technical solution, the depth of each intercepting channel is between 1 / 3 and 1 / 2 of the thickness of the intercepting block.

[0014] Another technical solution adopted by this utility model is as follows:

[0015] The molding structure of the automotive center console includes a moving mold and a fixed mold. The moving mold is provided with a moving template and a moving mold core. The fixed mold is provided with the multi-point controllable injection structure described in the previous technical solution. The end of the moving mold core facing the fixed mold core forms a second cavity that matches the first cavity.

[0016] As a further explanation of the above technical solution:

[0017] In the above technical solution, a slider is provided on both sides of the moving mold core in the X direction and on both sides of the moving mold core on the moving template, and a core is provided on the end of each slider facing the second cavity; a set of inclined pushers is slidably mounted on each slider, and the upper end of each set of inclined pushers can be detachably fixed on the fixed template; each set of inclined pushers can push a slider to slide on the moving template so that the core on it passes through the moving mold core and extends into the second cavity.

[0018] In the above technical solution, each set of inclined pushers includes two or more inclined braces. Several inclined braces are symmetrically arranged on both sides of the central axis of the slider, or evenly arranged on the slider. Each slider is provided with inclined holes that are adapted to each of the several inclined braces.

[0019] In the above technical solution, each slider has one or more slides at one end, the slides are located on the central axis of the slider, or several slides are symmetrically arranged on the slider; the moving template is provided with slide rails that are adapted to each of the slides.

[0020] In the above technical solution, the fixed mold base and / or sprue plate are further provided with a number of stripping rods. The end of each stripping rod passes through the sprue plate and the fixed mold plate and extends to a second flow channel. The end of each rod is a horn structure and its large end faces the second flow channel and extends into it.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the injection structure as a first flow channel, several straight and arc-shaped second flow channels and several third flow channels, and setting intercepting blocks on several second flow channels, the flow rate of some injection channels can be adjusted individually, thereby ensuring that the glue is injected evenly from multiple points into the cavity during the injection process, reducing the molding defect rate; by setting sliders that can slide relative to the moving mold core on the periphery of the moving mold plate, and setting a set of symmetrical or evenly arranged inclined supports that can slide relative to the moving mold core on each slider, the movement of the moving mold plate during mold opening and closing can be used to push each inclined support to smoothly drive the sliders closer to or away from the moving mold core, realizing the synchronous movement of the lateral core in four directions, so as to facilitate subsequent operations. The structure is simple and effective. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0029] like Figure 1-2 As shown, a multi-point controllable injection structure is provided on the fixed mold of the plastic mold. The fixed mold is provided with a mold base, a sprue plate 20, a fixed mold plate 30 and a fixed mold core 40. The fixed mold base is provided with a liquid storage tank 50. The end of the fixed mold core 40 facing the moving mold forms a first cavity. The multi-point controllable injection structure includes a first flow channel 1, several second flow channels 2 and several third flow channels 3.

[0030] To clearly demonstrate the glue injection structure, see attached... Figure 1The injection structure is visually demonstrated using the sprue structure after molding. The first flow channel 1 is located on the sprue plate 20 and is connected to the liquid storage tank 50. Several second flow channels 2 are located on the fixed template 30 near the end of the sprue plate 20. One end of each second flow channel 2 is connected to the first flow channel 1, and the other end extends away from the first flow channel 1. Several second flow channels 2 are provided with flow-blocking blocks 60 for controlling the flow rate of the glue. Each flow-blocking block 60 can be detachably fixed on the fixed template 30. One end of each third flow channel 3 is connected to the end of a second flow channel 2 away from the first flow channel 1, and the other end passes through the fixed template 30 and the fixed mold core 40 in sequence and is connected to the first cavity.

[0031] In this embodiment, the product 100 is large in size and uneven in thickness, and has a roughly symmetrical square structure. In order to enable the adhesive to quickly and evenly fill the cavity, the end of the first flow channel 1 is located at the center of the product's structural component. The number of second flow channels 2 is even, and they are arranged symmetrically on both sides of the first flow channel 1 in pairs. At least one set of second flow channels 2 is a straight flow channel, and at least one set of second flow channels 2 is an arc-shaped flow channel. When the first flow channel 1 is close to the third flow channel 3, the arc-shaped flow channel can extend the flow path of the adhesive, thereby delaying the adhesive from entering the cavity and achieving the purpose of uniformly injecting the adhesive into the cavity from multiple points.

[0032] To further adjust the flow rate and time of the adhesive entering the mold cavity, a flow-blocking block 60 is also provided in the straight flow channel. In this embodiment, each flow-blocking block 60 is detachably fixed on the fixed template 30, and has a flow-blocking channel 61 adapted to and connected to a second flow channel 2. The fixed template 30 has several grooves 31, each of which can accommodate one flow-blocking block 60, and its length is greater than the length of the flow-blocking block 60; the depth of each flow-blocking channel 61 is between 1 / 3 and 1 / 2 of the thickness of the flow-blocking block 60. During production, pushing the flow-blocking block 60 to slide in the groove 31 can change the contact area between the flow-blocking channel 61 and the second flow channel 2, thereby adjusting the flow rate of the adhesive in the second flow channel 2 per unit time, so as to better balance the flow rate and flow of the adhesive entering the mold cavity; or a flow-blocking block 60 can be directly flipped over to directly block a specific second flow channel 2. In this embodiment, the intercepting channel 61 is a straight structure, and its relatively shallow depth ensures that the intercepting block 60 can completely block the second channel 2 when it is flipped over.

[0033] The following examples illustrate the application of the above embodiments in the molding of automotive center console panels. Figure 3 As shown, the mold includes a moving mold and a fixed mold. The moving mold is provided with a moving template 70 and a moving mold core 80. The fixed mold is provided with a multi-point controllable injection structure as described in the above embodiment. The end of the moving mold core 80 facing the fixed mold core 40 forms a second cavity that matches the first cavity.

[0034] In this embodiment, a slider 90 is provided on both sides of the moving mold core 80 in the X direction and on both sides of the moving mold core 80 on the moving template 70. Each slider 90 has a core at its end facing the second cavity. A set of inclined pushers is slidably mounted on each slider 90. The upper end of each set of inclined pushers can be detachably fixed on the fixed template 30. Each set of inclined pushers can push a slider 90 to slide on the moving template 70 so that the core on it passes through the moving mold core 80 and extends into the second cavity.

[0035] In order to push the four cores 91 towards the second core simultaneously during the mold closing process and avoid mold jamming, each set of inclined push parts includes two or more inclined supports 4. Several inclined supports 4 are symmetrically arranged on both sides of the central axis of the slider 90, or evenly arranged on the slider 90. Each slider 90 is provided with inclined holes that are adapted to each of the inclined supports 4. Each end of each slider 90 is provided with one or more slides 5. The slides 5 are located on the central axis of the slider 90, or several slides 5 are symmetrically arranged on the slider 90. The moving template 80 is provided with slide rails that are adapted to each of the slides 90.

[0036] To facilitate the removal of the sprue from the fixed mold, such as Figure 1 , 3 As shown in Figure 4, the fixed mold base and / or sprue plate 20 are also provided with several stripper rods 6. The end of each stripper rod 6 passes through the sprue plate 20 and the fixed mold plate 30 and extends to a second runner 2. The end of each stripper rod 6 is a flared structure with its large end facing the second runner 2 and extending into it. During operation, with the mold closing action, the fixed mold plate 20 is pressed tightly against the fixed mold base and the sprue plate 30, and the end of the stripper rod 6 extends into the second runner 2. After the injection molding is completed, the mold is opened. Under the action of the clamping mechanism (the limiting structure between the moving mold plate and the fixed mold plate), the moving mold first pulls the fixed mold plate away from the fixed mold base and the sprue plate, so that the stripper rod 6 is disengaged from the sprue. The flared structure at its end pulls the sprue in the runner out of the groove in the fixed mold plate 30, which facilitates the subsequent sprue removal action.

[0037] The principle and working process of controlling the mold opening process by a buckle machine on a plastic mold are common knowledge for those skilled in the art. The specific structure of the buckle machine and its connection with the structural components on the mold will not be described in detail here.

[0038] This invention features a glue injection structure consisting of a first flow channel 1, several straight and arc-shaped second flow channels 2, and several third flow channels 3. A flow-blocking block 60 is provided on several second flow channels 2, allowing the flow rate of some injection channels to be adjusted individually. This ensures that the glue is evenly injected into the cavity from multiple points during the injection process, reducing the molding defect rate. Furthermore, by setting sliders 90 that can slide relative to the moving mold core 80 on the periphery of the moving mold plate 70, and by providing a set of symmetrically or evenly arranged inclined supports 4 on each slider 90, the movement of the moving mold plate 70 during mold opening and closing can push the inclined supports 4 to smoothly move the sliders 90 closer to or away from the moving mold core 80, achieving synchronous movement of the lateral cores in four directions for subsequent operations. The structure is simple and effective.

[0039] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
