Description

Technical Field

[0001] This utility model relates to the field of injection molds, specifically to an injection mold for the lower shell of an actuator. Background Technology

[0002] The lower housing of an automotive headlight actuator consists of two structures: a pin and a plastic shell. During manufacturing, the pin is placed in a mold and injection molded to form the plastic shell, which is then fixed to the pin. Traditional manufacturing equipment places the pin in the lower mold of an injection mold, then closes the mold to position and fix the pin, before injection molding connects the pin to the plastic shell to form the lower housing. This method makes the pin prone to vibration during the injection molding process, resulting in low molding accuracy of the lower housing.

[0003] Therefore, it is necessary to provide an injection mold for the lower housing of the actuator. Summary of the Invention

[0004] The present invention provides an injection mold for the lower shell of an actuator, which effectively solves the problem of low molding precision in existing lower shells.

[0005] The technical solution adopted in this utility model is:

[0006] The actuator lower housing injection mold includes an upper mold, a lower mold, and an injection system mounted on the upper mold. The upper mold includes an upper fixed plate, an upper template, and an upper mold core mounted on the upper template. The lower mold includes a lower fixed plate, a square iron plate, a lower template, a lower mold core mounted on the lower template, and an ejector pin assembly mounted on the lower fixed plate. Several upper mold cores are horizontally arranged, and each lower mold core corresponds to one of the upper mold cores. The lower mold also includes several automatic fixing components mounted on the lower template, each corresponding to one of the lower mold cores. The upper mold core, lower mold core, and ejector pin assembly form a cavity. Each automatic fixing component includes a cylinder mounted on the lower template, a first block mounted on the cylinder output end, and a second block mounted on the first block. The first and second blocks form a slot for clamping the exposed end of the PIN pin.

[0007] Furthermore, the glue injection system includes a glue injection port on the upper fixed plate, a first tube horizontally arranged on the upper template, and several second tubes vertically arranged on the upper template and passing through the upper mold core into the cavity, with the upper end of the second tubes connected to the first tube.

[0008] Furthermore, a pressure block is also provided on the upper mold core, which can press the second block tightly.

[0009] Furthermore, the ejector pin assembly includes a needle plate disposed on the lower fixed plate, a plurality of ejector pins disposed on the needle plate, and a push rod slidably disposed on the lower fixed plate and fixedly connected to the lower end face of the needle plate.

[0010] Furthermore, a position sensor is also provided on the lower fixing plate, which is used to sense the position of the needle plate.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] like Figure 1As shown, the actuator lower shell injection mold provided in the embodiment of this application has a structure including an upper mold, a lower mold, and an injection system 10 disposed on the upper mold. The upper mold includes an upper fixed plate 1, an upper template 2, and an upper mold core 3 disposed on the upper template 2. The lower mold includes a lower fixed plate 4, a square iron 5, a lower template 6, a lower mold core 7 disposed on the lower template 6, and an ejector pin assembly 8 disposed on the lower fixed plate 4. Several upper mold cores 3 are horizontally arranged, and each lower mold core 7 corresponds to one upper mold core 3. The lower mold also includes several automatic fixing assemblies 9 disposed on the lower template 6. Figure 2 , Figure 3 and Figure 4 As shown, the automatic fixing component 9 corresponds one-to-one with the lower mold core 7. The upper mold core 3, the lower mold core 7 and the ejector pin assembly 8 form a cavity. The automatic fixing component 9 includes a cylinder 91 disposed on the lower mold plate 6, a first block 92 disposed on the output end of the cylinder 91 and a second block 93 disposed on the first block 92. The first block 92 and the second block 93 form a slot 901 for clamping the exposed end of the PIN pin.

[0020] In actual use, the PIN pin 100 is placed on the lower mold core 7 via an external transfer mechanism. Then, the upper mold moves downward, causing the upper mold core 3 to close with the lower mold core 7. Subsequently, the cylinder 91 drives blocks 92 and 93 to move towards the PIN pin, fixing the exposed end of the PIN pin outside the cavity to the retaining groove 901. After injection molding is completed, the PIN pin is fixed to the injection molded material to form the finished product. Then, the upper mold moves upward, and the ejector pin assembly 8 lifts the finished product from the lower mold core 7. The finished product is then transferred from the lower mold core 7 using an external transfer mechanism.

[0021] The above design allows for the simultaneous molding of multiple products, effectively improving work efficiency. The automatic fixing component 9 secures the pins, preventing vibration caused by adhesive flow during dispensing and ensuring product molding accuracy.

[0022] Specifically: such as Figure 2 As shown, the glue injection system 10 includes a glue injection port 101 on the upper fixed plate 1, a first tube 102 horizontally arranged on the upper template 2, and several second tubes 103 vertically arranged on the upper template 2 and passing through the upper mold core 3 into the cavity. The upper end of the second tube 103 is connected to the first tube 102.

[0023] In actual use, the glue enters the first tube 102 through the glue injection port 101, then flows along the first tube 102 to several second tubes 103, and finally flows into the mold cavity through the second tubes 103.

[0024] In the above design, the structural design and specific implementation of the injection system 10 can effectively realize simultaneous injection molding of several cavities.

[0025] Specifically: such as Figure 3 As shown, a pressure block 11 is also provided on the upper mold core 3, which can press the second block 93.

[0026] In the above design, by pressing the second block 93 with the pressure block 11, the exposed end of the PIN pin in the card slot 901 can be further fixed.

[0027] Specifically: such as Figure 5 As shown, the ejector pin assembly 8 includes a needle plate 81 disposed on the lower fixed plate 4, a plurality of ejector pins 82 disposed on the needle plate 81, and a push rod 83 slidably disposed on the lower fixed plate 4 and fixedly connected to the lower end face of the needle plate 81.

[0028] In actual use, the push rod 83 is driven by an external drive mechanism to raise and lower the needle plate 81, so that the needle plate 81 drives the ejector pin 82 to rise and fall synchronously.

[0029] In the above design, the structural design and specific implementation of the ejector pin assembly 8 facilitate the ejection of the finished product.

[0030] Specifically: such as Figure 5 As shown, a position sensor 84 is also provided on the lower fixing plate 4, which is used to sense the position of the needle plate 81.

[0031] In actual use, when the position sensor 84 detects that the needle plate 81 has descended to the predetermined position, it sends the position information of the needle plate 81 to the external PLC control mechanism, thereby causing the external drive mechanism to stop driving the push rod 83 to move.

[0032] In the above design, the sensor settings facilitate the automatic positioning of the needle plate 81.

[0033] In further detail, it should be understood that the above description is only a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
