Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, and relates to a core-pulling injection mold for an electric vehicle front cover. Background Technology

[0002] Injection molds are a type of equipment widely used in industrial production. Inside an injection mold, there is a molding cavity for shaping. Plastic raw materials are heated to a molten state and then injected into the molding cavity inside the mold. After the molding cavity is filled, the mold is rapidly cooled, and the molten plastic raw materials cool and solidify to form a plastic part with the desired structure. Using injection molds to produce plastic products has advantages such as high precision and high efficiency.

[0003] The outer shell of an electric vehicle is mainly composed of plastic parts. The front cover of the electric vehicle is part of the outer shell. The inside of the front cover is used to connect the steering handle, and the top of its surface is also used to install the display instrument. In order to facilitate the driver's observation of the instrument, the instrument mounting slot on the front cover needs to be set at an angle. If traditional injection molds are used for production, there will be technical problems such as difficulty in demolding. Summary of the Invention

[0004] The purpose of this utility model is to address the problems existing in the current technology by proposing a core-pulling injection mold for the front cover of an electric vehicle. The technical problem to be solved by this utility model is: how to make the front cover easily demolded from the mold.

[0005] The objective of this utility model can be achieved through the following technical solution: A core-pulling injection mold for an electric vehicle front cover, comprising a top plate, a moving template, a fixed template, a foot plate, and a bottom plate arranged in sequence. A molding cavity is provided at the connection between the moving template and the fixed template. A shell for injection molding is provided inside the molding cavity. A slider is provided inside the moving template. The slider is obliquely arranged and its bottom is inserted into the molding cavity. An oblique molding part is provided at the bottom of the slider. A connecting block is provided at the top of the slider. Horizontally arranged slide rails are provided on both sides of the connecting block. The top of the connecting block is fixedly connected to the top plate. The top plate is longitudinally slidably connected to the moving template.

[0006] In this design, the shell is cooled and formed inside the molding cavity. Since the molding part at the bottom of the molding block is inserted into the molding cavity, it can form an oblique groove structure on the shell. During the demolding process, the top plate is first pulled outward, and the top plate drives the fixed connecting block and slider to move outward together. Since the slider is obliquely set, through the structure of the slide rails on both sides of the connecting block, the slider can obliquely pull the core outward, and then push the moving template and the fixed template to separate from the mold. Through the ejection structure inside the fixed template, the shell is ejected from the molding cavity, realizing convenient demolding. In the above way, the oblique slider can form an oblique groove structure on the shell. The first movement of the top plate pulls the core, causing the slider to be pulled out of the molding cavity. The second movement of the moving template opens the mold and ejects the shell of the car head cover, making the car head cover conveniently demolded from the mold.

[0007] In the aforementioned core-pulling injection mold for the electric vehicle front cover, guide posts are fixedly connected at the four corners of the top plate, and corresponding guide sleeves are provided at the corners of the moving and fixed templates. The guide posts are slidably inserted into the guide sleeves. The guide posts and guide sleeves cooperate to allow the moving and fixed templates to slide open or close.

[0008] In the aforementioned core-pulling injection mold for the electric vehicle front cover, the moving template is slidably connected to the fixed template, the fixed template is fixedly connected to the foot plate, and the foot plate is fixedly connected to the bottom plate. After the moving template is slidably separated from the fixed template, it is convenient to eject the shell inside the molding cavity.

[0009] In the aforementioned core-pulling injection mold for the electric vehicle front cover, a mounting groove is provided at the center of the housing, and an oblique ring edge is provided at the edge of the mounting groove. The molding part is inserted into the mounting groove. The mounting groove is formed by the molding part at the bottom of the molding block, and an oblique ring edge structure is formed at the edge of the mounting groove to facilitate the installation of instruments and other structures inside the mounting groove.

[0010] In the aforementioned core-pulling injection mold for the electric vehicle front cover, a slidingly connected push plate is provided on the inner side of the foot plate. The push plate has several fixedly connected slides, each slide having a hinged inclined push rod. The top of each inclined push rod slides through the fixed mold plate and extends to the bottom of the molding cavity. After the fixed mold plate separates from the moving mold plate, the inner push plate is pushed upwards. Because of the slides between the push plate and the inclined push rods, the push plate can obliquely push the inclined push rods upwards. The inclined push rods extend from the bottom of the fixed mold plate, pushing the shell out of the molding cavity.

[0011] In the aforementioned core-pulling injection mold for the electric vehicle front cover, the base plate is provided with a feed port, and the bottom of the feed port is provided with a connected nozzle. One end of the nozzle passes through the fixed mold plate and is connected to the molding cavity. Molten plastic heated to a molten state is injected from the feed port and injected into the molding cavity through the nozzle connected to the bottom.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. In this solution, the inclined slider can form an inclined mounting groove structure on the shell. The first movement of the top plate is used to pull the core, so that the slider is pulled out of the molding cavity. The second movement of the moving plate opens the mold and ejects the shell of the car head cover, so that the car head cover can be easily demolded from the mold. Attached Figure Description

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] Example

[0021] like Figure 1 As shown, the core-pulling injection mold for the front cover of an electric vehicle includes a top plate 1. The bottom of the top plate 1 is provided with a slidingly connected moving template 2. The bottom of the moving template 2 is provided with a slidingly connected fixed template 3. The bottom of the fixed template 3 is provided with a fixed foot plate 4. The bottom of the foot plate 4 is provided with a fixed bottom plate 5. The inner side of the foot plate 4 is provided with a slidingly connected push plate 4a.

[0022] like Figure 2 As shown, a forming cavity 6 is provided between the moving template 2 and the fixed template 3. The bottom plate 5 is provided with a feed inlet 5a. The bottom of the feed inlet 5a is provided with a connected nozzle 5b. One end of the nozzle 5b passes through the fixed template 3 and is connected to the forming cavity 6. The push plate 4a is provided with several fixed sliding seats 4b. Each sliding seat 4b is provided with a hinged inclined push rod 4c. The top end of the inclined push rod 4c slides through the fixed template 3 and extends to the bottom of the forming cavity 6.

[0023] like Figure 3 As shown, the top plate 1 has guide posts 1a fixedly connected at its four corners, and guide sleeves 1b are provided at the corners of the moving template 2 and the fixed template 3. The guide posts 1a are slidably inserted into the guide sleeves 1b. The moving template 2 has a slider 2a slidably connected inside. The slider 2a is obliquely arranged and its bottom is inserted into the molding cavity 6. The top of the slider 2a has a connecting block 7 slidably connected. The top of the connecting block 7 is fixedly connected to the top plate 1.

[0024] like Figure 4 As shown, the connecting block 7 has horizontally arranged slide rails 7a on both sides, the bottom of the slider 2a has an inclined molding part 2a1, the molding cavity 6 has an injection-molded shell 8 inside, the shell 8 has an installation groove 8a at the center, the edge of the installation groove 8a has an inclined ring edge 8b, and the molding part 2a1 is inserted into the installation groove 8a.

[0025] The working principle of this solution is as follows: Figure 1-4 As shown, molten plastic heated to a molten state is injected into the inlet 5a and then into the molding cavity 6 through the nozzle 5b connected to the bottom. After the molding cavity 6 is completely filled, the mold is cooled to allow the molten plastic to cool and form the shell 8. The top plate 1 is then pulled outward, causing the connecting block 7 and the slider 2a to move outward together. Since the slider 2a is angled, it can be pulled outward at an angle through the structure of the slide rails 7a on both sides of the connecting block 7. This pushes the moving template 2 to separate from the fixed template 3. Finally, the internal push plate 4a is pushed upward. Since the push plate 4a and the inclined ejector rod 4c are connected by a sliding seat 4b, the push plate 4a can push the inclined ejector rod 4c upward at an angle. The inclined ejector rod 4c extends from the bottom of the fixed template 3, pushing the shell 8 out of the molding cavity 6, allowing the head cover to be easily demolded from the mold.
