Description

Technical Field

[0001] This utility model relates to the field of radar component molding technology, and in particular to a molding die for internal radar components. Background Technology

[0002] Currently, the mass production of core components inside radars mostly adopts die casting molding. However, due to the complex structure of these parts, traditional integral mold cavities cannot achieve complete molding of the corresponding structures. Generally, structures such as sliders and diagonal braces are used to cooperate in molding. However, the fit between the diagonal braces and the slider requires extremely high precision. Long-term high-frequency movement can easily lead to wear on the mating surfaces, causing the slider to jam and further exacerbating the difficulty of demolding. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a quick-release molding die for radar internal components.

[0004] Therefore, the technical solution of this utility model is: a molding die for internal radar components, including a front mold frame, a rear mold frame, and an ejection mechanism. The front mold frame has at least one first molding groove, and the rear mold frame has at least one second molding groove, with the first and second molding grooves combined to form a cavity. The rear mold frame has multiple sliders, with the front ends of the sliders inserted into the cavity. The sliders have oblique insertion holes, and the front mold frame has oblique insertion rods inserted into the oblique insertion holes, with the two working together. The rear end of the sliders is fixed with a support rod, and a spring is fitted on the support rod. The ejection mechanism includes an ejection base, with oblique supports and several ejector pins on the ejection base. The top of the oblique supports has a locking block forming part that extends into the cavity.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the rear mold frame is provided with a fixing plate, the rear end of the support rod passes through the through hole of the fixing plate, one end of the spring abuts against the rear end of the support rod, and the other end abuts against the fixing plate.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the rear mold frame is provided with a guide rail for the slider to slide along, and the slider slides along the guide rail on both sides; the front end of the slider is a forming part that works in conjunction with the cavity.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the front mold frame and the rear mold frame are assembled to form two symmetrical cavities. The front mold frame has a recessed gate in the middle, and the rear mold frame has a boss that is opposite to the gate. The boss is located in the middle of the two cavities, and the two sides of the boss are connected to the cavities through the sprue flow channel.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the inlet channel is provided with ejector pin holes for ejector pins to pass through.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. A spring is installed on the side of the slider. The elastic force applied by the spring can form a continuous lateral preload, so that the slider always fits the mating reference surface of the diagonal brace, realizing real-time compensation for wear gaps. The spring can push the slider to move slightly in the direction of the elastic force to fill the gaps caused by wear, avoid movement shaking caused by excessive gaps, and reduce the risk of jamming.

[0010] 2. By utilizing the angled insertion holes on the front mold base and the angled insertion holes on the slider, the slider can be moved. When the mold is closed, the forming part at the front end of the slider is inserted into the cavity. When the mold is demolded, the slider is driven to leave the cavity. In conjunction with the ejection mechanism, the demolding is completed in one go, improving demolding efficiency. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0015] See the attached drawings. The radar internal component molding mold described in this embodiment includes a front mold frame 1, a rear mold frame 2, and an ejection mechanism 3. The front mold frame 1 is provided with a front mold core 11, and the front mold core 11 is provided with two centrally symmetrical first molding grooves 12. The rear mold frame 2 is provided with a rear mold core 21, and the rear mold core 21 is provided with two second molding grooves 22. The first molding grooves 12 and the second molding grooves 22 are combined to form a cavity.

[0016] The rear mold frame 2 is provided with multiple guide rails for the slider 23 to slide along. The slider 23 slides along the guide rails on both sides and is located on the upper and lower sides of the cavity and on the side away from another cavity. The front end of the slider 23 is provided with a forming part 24, which can be inserted into the cavity and work with it. The slider 23 is provided with a slanted insertion hole 25, and the front mold frame 1 is provided with a slanted insertion rod 13, which is inserted into the slanted insertion hole 25. When the front mold frame 1 and the rear mold frame 2 are closed, the slanted insertion rod 13 can drive the slider 23 to move towards the cavity, so that the forming part 24 of the slider 23 is inserted into the cavity for die casting. After die casting is completed, the front mold frame 1 and the rear mold frame 2 are separated, and the slanted insertion rod 13 can drive the slider 24 away from the cavity for easy demolding.

[0017] The rear mold frame 2 is provided with a fixing plate 26, and the fixing plate 26 is provided with a through hole; the rear end of the slider 23 is fixed with a support rod 27, the rear end of the support rod 27 passes through the through hole of the fixing plate 26, and a spring 28 is fitted on the support rod 27. One end of the spring 28 abuts against the rear end of the support rod 27, and the other end abuts against the fixing plate 26. The spring 28 applies an outward force to the slider 23, so that the slider always fits against the inclined support rod 13. The spring 28 can push the slider 23 to move slightly in the direction of the elastic force to fill the gap caused by wear and avoid the movement shaking caused by excessive gap.

[0018] The front mold frame 1 has a recessed sprue 14 in the middle, and the rear mold frame 2 has a boss 29 opposite to the sprue 14. The boss 29 is located between the two cavities, and the two sides of the boss 29 are connected to the cavity through the sprue flow channel 210. The sprue flow channel 210 has an ejector pin hole 211 for ejector pins to pass through.

[0019] The ejection mechanism 3 includes an ejection base 31, on which are provided inclined supports 32 and several ejector pins 33. The top of the inclined supports 32 is provided with a locking block forming part 34, which extends into the cavity. Under the action of the power mechanism, the ejection base 31 moves toward the rear mold frame 2. During the movement, the locking block forming part 34 at the front end of the inclined supports 32 separates from the locking block on the die-cast radar internal component 4, and the ejector pins 33 can eject the radar internal component 4, completing the demolding.

[0020] The demolding steps are as follows: After injection molding is completed, the front mold base 1 and the rear mold base 2 begin to separate; As the front mold base 1 moves in the opposite direction to the rear mold base 2, the inclined insertion rod 13 on the front mold base 1 is gradually pulled out from the inclined insertion hole 25 of the slider 23 of the rear mold base 2; the slider 23 is driven by the inclined insertion rod 13 and slides outward along the guide rail on the rear mold base 2, and the forming part 24 at the front end of the slider 23 is smoothly pulled out from the cavity, completing the lateral core pulling action. The front mold base 1 continues to move until it is completely separated from the rear mold base 2. At this time, the gate 14 separates from the boss 29 on the rear mold base 2, cutting off the connection between the gate and the product. The ejector base 31 drives the inclined support 32 and ejector pin 33 to move forward. When the inclined support 32 moves, the top block forming part 34 detaches the product and simultaneously pushes the radar internal parts 4 in the cavity upward. At the same time, the ejector pin 33 passes through the inlet channel and the ejector pin hole 211 on the cavity, pushing out the waste residue in the channel and the radar internal parts 4 at the same time. The ejection mechanism 3 continues to operate until the product and runner waste are completely separated from the second forming groove 22 of the rear mold frame 2. At this time, the formed radar internal parts and waste can be removed manually or mechanically. The ejector mechanism 3 returns to its initial position to prepare for the next injection molding. During subsequent mold closing, the front mold base 1 resets, the angled insert rod 13 re-inserts into the angled insert hole 25 to push the slider 23 to reset, and the spring 28 is compressed, restoring it to the molding state.

[0021] This embodiment achieves lateral core pulling through the cooperation of the inclined insert rod and the slider, and uses the coordinated action of the ejector pin and the inclined support to complete the synchronous ejection of the product and the runner waste, ensuring a smooth and efficient demolding process and avoiding damage to the product.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
