Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to an oblique inner drawing mechanism of a mold for a headlight mask of an electric vehicle. Background Art

[0002] As the main lighting equipment of electric vehicles, headlights play a vital role in the driving process of the vehicle, especially at night. Existing electric vehicle headlights usually include structures such as headlight masks, lamp holders and reflective bowls. The headlight masks are processed through injection molds, so an oblique inner extraction mechanism is required.

[0003] In the prior art, for example, patent number CN202223452779.X discloses a core-pulling mechanism in the slider of the electric vehicle headlight mask mold. This technical solution facilitates the reciprocating movement of the slider through the cooperation of the push rod and the first return spring. The reciprocating movement of the slider drives the extension and contraction of the connecting rod, and the extension and contraction of the connecting rod drives the movement of the rectangular block. The movement of the rectangular block facilitates the separation of the rectangular block from the core of the electric vehicle headlight shell mold, thereby achieving a quick demolding effect, replacing the traditional demolding by ejector pin, and effectively ensuring the structural integrity of the headlight mask.

[0004] The disadvantages of the core-pulling mechanism disclosed above are that the slider adopts an integral structure, and has more wear surfaces with the oblique guide rod during use, and the slider needs to be replaced as a whole during subsequent wear, which is very inconvenient. Based on this, we designed an oblique inward pulling mechanism for the electric vehicle headlight mask mold. Summary of the Invention

[0005] The purpose of the utility model is to provide an oblique inward drawing mechanism for a headlight mask mold of an electric vehicle, so as to solve the problems raised in the above-mentioned background technology.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an oblique inner drawing mechanism for a headlight mask mold of an electric vehicle, comprising an upper mold body, a lower mold body, an oblique guide rod, a first slider portion, and a second slider portion, wherein the head portion of the oblique guide rod is connected to a specific groove opening of the upper mold through a guide rod insert, a slider insert is provided at a specific side opening of the lower mold, one side of the slider insert is connected to the first slider portion, a guide rod channel is formed between the first slider portion and the second slider portion, the oblique guide rod is located in the guide rod channel and enables the oblique guide rod to extend the first slider portion and the second slider portion to move obliquely upward, a connecting portion is provided at the tail portion of the oblique guide rod, and the connecting portion is connected to the lower mold body through a positioning assembly;

[0007] The positioning component includes a flat key recess opened at the end of the connecting part and a key column keyed to the flat key recess. The key column is connected to the lower mold body, and the flat key recess of the connecting part is assembled and connected to the key column.

[0008] The aforementioned oblique inward-drawing mechanism for the electric vehicle headlight mask mold also includes a slider guide seat with a ball guide groove at its top end. A ball bearing is embedded and mounted at the bottom end of the second slider portion, which slides along the ball guide groove. This arrangement ensures good guidance and low friction during the movement of the second slider portion, facilitating quick and easy separation of the second slider portion from the oblique guide rod.

[0009] The aforementioned oblique inward-drawing mechanism for the electric vehicle headlight mask mold also includes a side stopper with a raised block on one side. A limit hole is provided on one side of the second slider, with the raised block located within the limit hole. This arrangement provides a good limit effect, facilitating the positioning of the side of the second slider, preventing it from slipping, and enabling better injection molding after the upper and lower mold bodies are closed.

[0010] In the aforementioned oblique inward-drawing mechanism for the electric vehicle headlight mask mold, a pull rod is provided on the other side of the side stop block. A pin-connected curved rod is provided at the top of the pull rod. A locating pin is provided at one end of the pin-connected curved rod. This locating pin is pin-connected to the upper mold body. This arrangement facilitates the lateral movement of the side stop block, allowing it to quickly disengage from the upper and lower mold bodies, facilitating the removal of the second slide unit.

[0011] In the aforementioned oblique inward-drawing mechanism for the electric vehicle headlight mask mold, a channel is defined on the side of the lower mold body. An insert rod is positioned within the channel, one end of which engages with the side of the connecting portion. This configuration further limits the position of the connecting portion at the tail end of the oblique guide rod, ensuring that the bottom end of the connecting portion maintains a certain level of positional accuracy after the upper and lower mold bodies are closed, ensuring that the mold cavities of the upper and lower mold bodies can form the completed injection molding cavity for the electric vehicle headlight mask.

[0012] In the aforementioned oblique inward-drawing mechanism for the electric vehicle headlight mask mold, the bottom end of the second slider portion is in contact with the top end of the slider guide seat. This arrangement ensures close contact between the second slider portion and the slider guide seat, thereby ensuring a certain degree of motion stability when the second slider portion moves relative to the slider guide seat.

[0013] Compared with the prior art, the advantages of the oblique inner withdrawal mechanism of the electric vehicle headlight mask mold of the present invention are as follows: a slider insert is provided at the specific side opening of the lower mold to connect the first slider part, a guide rod channel is formed between the first slider part and the second slider part, the oblique guide rod is located at the guide rod channel and enables the oblique guide rod to extend the first slider part and the second slider part to move obliquely upward, and a side limit block and a protruding block are provided. The protruding block is located inside the limit hole of the second slider part, has a good limiting effect, is convenient for limiting the side of the second slider part, avoids the second slider part from slipping, and enables the upper mold body and the lower mold body to be molded together. After that, the injection molding operation can be carried out better; at the same time, the side limit blocks can be quickly separated from the upper mold body and the lower mold body, which is convenient for taking out the second slider part; and the split first slider part and the second slider part are adopted, which reduces the contact area with the surface of the oblique guide rod, thereby achieving the effect of reducing wear; by providing a slider guide seat and providing a ball guide groove at the top of the slider guide seat, the bottom end of the second slider part is embedded with a mounting ball, and the ball slides along the ball guide groove, so that the second slider part has good guiding performance and low friction effect during movement, which is convenient and fast to separate the second slider part from the oblique guide rod.
