Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a reversing radar bracket demolding mechanism. Background Technology

[0002] Reversing radar is a safety aid device for parking or reversing a car. It can inform the driver of the surrounding obstacles with sound or more intuitive display, eliminating the trouble caused by the driver having to look around when parking, reversing and starting the vehicle, and helping the driver to eliminate blind spots and blurred vision.

[0003] Existing automotive radar injection molds, such as the Chinese patent with authorization announcement number CN221677954U entitled "An Injection Mold for an Automotive Radar Bracket," disclose an automotive radar bracket injection mold, including an upper mold body and a lower mold body that docks with the upper mold body. The lower mold body is fixedly connected to a support base, and a water pump is fixedly installed on the support base. The output end of the water pump is fixedly connected to the water storage cavity of the lower mold body. A return pipe is fixedly installed on the lower mold body and is connected to the water storage cavity of the lower mold body. Two sliding grooves are formed on the support base.

[0004] For example, Chinese patent CN214491504U, entitled "An Injection Mold for an Automotive Radar Bracket," discloses an injection mold for an automotive radar bracket, including a base. Support columns are fixedly mounted on the four corners of the base, and a top plate is fixedly mounted on the support columns. A hydraulic cylinder is fixedly mounted on the top plate, and the piston rod of the hydraulic cylinder passes through the top plate. An upper mold body is fixedly mounted below the piston rod of the hydraulic cylinder. The upper mold body has an injection port. A lower mold body, a water pump, and a water tank are fixedly mounted on the base. A water storage cavity is opened on the side wall of the lower mold body, and the input end of the water pump is connected to the lower end of the water tank through a water pipe.

[0005] Existing technologies, including the aforementioned patents, can meet the injection molding requirements of automotive radar brackets to a certain extent. It is known that during injection molding, liquid raw materials are injected into the mold cavity through the sprue. After the raw materials cool, a sprue is formed at the sprue while the workpiece is being formed. However, in existing technologies, after the workpiece is injection molded and cooled, it is usually necessary to demold the workpiece from the mold core and then cut the sprue off the workpiece, affecting the efficiency of product processing. Utility Model Content

[0006] The purpose of this invention is to provide a reversing radar bracket demolding mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reversing radar bracket demolding mechanism, comprising a mold body, a mold core installed inside the mold body, and a workpiece and a material rack integrally formed with the workpiece being injection molded inside the mold body via inserts; an ejector plate is slidably connected to the mold body, the ejector plate is provided with a cutting part, and a limiting part is also provided on the mold body to fix the material rack; during the stroke in which the ejector plate drives the workpiece upward from the mold core, the workpiece is separated from the material rack by the cutting part.

[0008] Furthermore, the cutting component includes a support frame installed inside the mold core, on which a cutting blade is slidably connected, and the cutting blade is mounted on the ejector plate via a connecting part.

[0009] Furthermore, the connecting part includes a connecting rod fixedly connected to the bottom of the cutting blade, and the connecting rod is mounted on the ejector plate by bolts.

[0010] Furthermore, the support frame is provided with a vertical trapezoidal groove, and the cutting blade is slidably connected to the support frame through the vertical trapezoidal groove.

[0011] Furthermore, the support frame has a notch, and the cutting blade is slidably connected to the incision.

[0012] Furthermore, the limiting part includes a pressure block installed on the mold body, and the pressure block is adapted to the support frame through the mounting part.

[0013] Furthermore, the mounting part includes a protrusion disposed on the top of the support frame, and a groove adapted to the protrusion is provided on the bottom of the pressure block. When the pressure block is installed on the support frame, the protrusion is engaged in the groove.

[0014] Furthermore, the support frame is provided with an injection port.

[0015] Furthermore, the injection port is conical.

[0016] Furthermore, the mold body is provided with a power unit for driving the ejector plate to slide.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: When the workpiece needs to be demolded after injection molding, the mold body first opens to separate the fixed mold from the moving mold. After the mold body opens to the predetermined position, the ejector plate is driven to move, which facilitates the unloading of the workpiece. During the stroke of the ejector plate driving the workpiece out of the mold core, the limiting component fixes the material rack. At this moment, the cutting component separates the workpiece from the material rack. With the continuous movement of the ejector plate, the workpiece is ejected from the mold core, which facilitates the unloading of the workpiece. When the unloading of the workpiece is completed, the workpiece is in a separated state from the material rack. Therefore, it is necessary to cut the material rack and the workpiece separately, which greatly improves the working efficiency of the demolding mechanism and makes it more effective.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A workpiece 3 and a material holder 4 integrally formed with the workpiece 3 are injection molded inside the mold body 1 via inserts, meeting the molding requirements of the workpiece 3. An ejector plate 5 is slidably connected to the mold body 1, facilitating the ejection of the workpiece 3. The ejector plate 5 is equipped with a cutting part that separates the workpiece 3 from the material holder 4. The mold body 1 also has a limiting part that fixes the material holder 4 while facilitating the injection molding of the workpiece 3. During use, when demolding is required after injection molding of workpiece 3, the mold body 1 first opens to separate the fixed mold from the moving mold. After the mold body 1 opens to the predetermined position, the ejector plate 5 is driven to move, facilitating the unloading of workpiece 3. During the upward stroke of the ejector plate 5 pushing workpiece 3 out of the mold core 2, the limiting component fixes the material rack 4. At this moment, the cutting component separates workpiece 3 from the material rack 4. With the continuous movement of the ejector plate 5, workpiece 3 is pushed out of the mold core 2, facilitating unloading. When unloading is complete, workpiece 3 is separated from the material rack 4, so the material rack 4 and workpiece 3 need to be cut off separately, greatly improving the working efficiency of the demolding mechanism and resulting in better performance.

[0031] In the embodiments provided by this utility model, the cutting component includes a support frame 7 installed inside the mold core 2.

When the ejector plate 5 moves, it will drive the cutting blade 9 to move together, thereby cutting the workpiece 3 from the material rack 4 to meet the working requirements.

[0032] In the embodiments provided by this utility model, a vertical trapezoidal groove is provided on the support frame 7, and the cutting blade 9 is slidably connected to the support frame 7 through the vertical trapezoidal groove, which further improves the stability of the cutting blade 9 when sliding and makes the use effect better.

[0033] In the embodiment provided by this utility model, a notch 10 is provided on the support frame 7, and the cutting blade 9 is slidably connected to the notch, which makes it easier for the cutting blade 9 to cut the material rack 4 and meet the work requirements.

[0034] In the embodiments provided by this utility model, the limiting part includes a pressure block 8 installed on the mold body 1. The pressure block 8 is adapted to the support frame 7 through the mounting part. The mounting part includes a protrusion provided on the top of the support frame 7. A groove adapted to the protrusion is opened on the bottom of the pressure block 8. When the pressure block 8 is installed on the support frame 7, the protrusion is engaged in the groove, thereby improving the stability of the pressure block 8 and the support frame 7 during installation and achieving better performance.

[0035] In the embodiments provided by this utility model, the support frame 7 is provided with an injection port 6, which is conical in shape. Therefore, after the workpiece 3 is demolded, the material rack 4 is directly clamped and unloaded by a robot, which facilitates the separation of the material rack 4 from the injection port 6 and meets the work requirements.

[0036] In the embodiments provided by this utility model, the mold body 1 is provided with a power unit for driving the ejector plate 5 to slide. The power unit is prior art and will not be described in detail here.
