Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically a car sensor injection mold that is easy to clean. Background Technology

[0002] Injection molds are a key tool used primarily in the injection molding process. They are used to heat and melt plastic material, which is then injected into the cavity of the mold. After cooling, the material is formed, ultimately yielding the desired plastic product. These molds are widely used in the manufacture of plastic parts, housings, toys, electronic components, etc. The housings of automotive sensors are also processed using this injection molding process.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN214111256U) discloses an easy-to-clean injection mold, comprising a base plate, a fixed frame fixedly connected to the top of the base plate, a cabinet door movably connected to the surface of the fixed frame via hinges, a hydraulic cylinder fixedly connected to the top of the inner cavity of the base plate, a movable plate fixedly connected to the output end of the hydraulic cylinder, an upper fixed mold fixedly connected to the bottom of the movable plate, and a servo motor fixedly connected to the bottom of the inner cavity of the fixed frame. This utility model, through the base plate, fixed frame, movable plate, hydraulic cylinder, screw, screw block, positioning plate, fan, connecting pipe, annular pipe, servo motor, and pressurizing nozzle, enables the device to achieve easy cleaning, solving the problem that existing injection molds on the market lack easy cleaning capabilities, leaving residual waste on the mold surface during injection molding, affecting the quality of subsequent injection molding, and hindering user operation.

[0004] Although the aforementioned patent uses pressurized gas to clean residual waste on the mold surface, the overall process of its equipment involves pouring, removing the mold, cleaning, and then resetting for pouring, repeating this cycle to complete the injection molding process. Because it is a single-station injection process, the cleaning process at each station cannot be completed during the injection molding process, thus reducing the injection molding efficiency of the equipment. At the same time, when performing high-pressure gas cleaning, only the lower mold is cleaned, and the upper mold cannot be cleaned, which further reduces the mold cleaning efficiency.

[0005] Therefore, this utility model provides an easy-to-clean automotive sensor injection mold to solve the above problems. Utility Model Content

[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.

[0029] like Figure 1-5 As shown, this utility model provides a convenient-to-clean automotive sensor injection mold, including a body 1, which includes a frame 11. Two sets of interlayer partitions 12 are arranged above the frame 11, and each set of interlayer partitions 12 is connected to a cleaning chamber hood 15 on its opposite side. Each cleaning chamber hood 15 contains a cleaning assembly and a blowing assembly. A first top plate 13 and a second top plate 14 are sequentially arranged above the interlayer partitions 12. A reciprocating assembly 5 is also provided, positioned above the frame 11. Two sets of mold assemblies 7 are arranged above the moving end, and the displacement end of the reciprocating assembly 5 moves left and right in a reciprocating manner. Driven by the reciprocating assembly 5, the two sets of mold assemblies 7 can move left and right in a reciprocating manner. Thus, when one set of mold assemblies 7 is directly below the first cylinder 2 for injection molding, the other set of mold assemblies 7 is inside the cleaning chamber cover 15. The cleaning assembly and the blowing assembly can thoroughly clean the mold assemblies 7, avoid empty running of the injection molding process, and effectively improve the injection molding efficiency of the device.

[0030] Furthermore, the mold assembly 7 includes a second cylinder 71. The lifting end of the second cylinder 71 is fixedly connected to the upper surface of the displacement end of the reciprocating assembly 5. An upper mold 72 is fixedly connected to the outer wall of the housing of the second cylinder 71 via a bracket. A lower mold 73 is located directly below the upper mold 72 and is also fixedly connected to the upper surface of the displacement end of the reciprocating assembly 5. A first cylinder 2 is fixedly connected to the upper surface of the second top plate 14. The lifting end of the first cylinder 2 extends to the lower part of the first top plate 13. A pouring nozzle 21 is fixedly connected to the lower part of the lifting end of the first cylinder 2 via a bracket. The pouring nozzle 21 and the pouring hole of the upper mold 72 are coaxially distributed. After the upper mold 72 and the lower mold 73 are squeezed against each other, the first cylinder 2 drives the pouring nozzle 21 to descend, so that the pouring nozzle 21 is sealed and inserted into the pouring hole of the upper mold 72. The injection molding process of the mold is completed by the automatic feeding of the material supply pipe behind the pouring nozzle 21 and the supporting equipment.

[0031] Furthermore, the purging assembly includes a high-pressure pipe 3, which is fixedly connected to the inner wall of the cleaning chamber hood 15 via a bracket. A booster nozzle 31 is fixedly connected to the outside of the high-pressure pipe 3. The high-pressure pipe 3 is used for purging the upper mold 72 and the lower mold 73. The high-pressure pipe 3 is interconnected with an external air supply system and controlled by a valve. The cleaning assembly includes a first motor 4, which is fixedly connected to the lower surface of the first top plate 13. A brush rod 41 is fixedly connected to the output end of the first motor 4. The brush rod 41 is used for cleaning the pouring holes of the upper mold 72. Furthermore, the pressure-boosting nozzles 31 are tilted to correspond to the injection parts of the upper mold 72 and the lower mold 73, respectively. Through the high-pressure gas supply from the high-pressure pipe 3, the pressure-boosting nozzles 31 spray out high-pressure gas to clean the residual waste on the surface of the upper mold 72 and the lower mold 73. During the process of the second cylinder 71 driving the upper mold 72 to move upward, the pouring hole of the upper mold 72 is sleeved on the outside of the brush rod 41. Then, the start of the first motor 4 drives the brush rod 41 to rotate, and at the same time cleans the inner wall of the pouring hole of the upper mold 72, which greatly improves the cleaning efficiency of the mold assembly 7.

[0032] Furthermore, the reciprocating assembly 5 includes a commutator 51, which is fixedly connected to the central through hole of the frame 11. The output shaft of the commutator 51 is connected to a gear 52, and a rack 53 meshes with the outside of the gear 52. A support plate 54 is fixedly connected to the upper surface of the rack 53, and the support plate 54 is the displacement end of the reciprocating assembly 5. A guide rail 55 is fixedly connected to the lower surface of the support plate 54, and a slider 56 is slidably connected to the outside of the guide rail 55. The slider 56 is fixedly connected to the upper surface of the frame 11. The frame 11 has through holes corresponding to the commutator 51 and the gear 52. A servo motor is connected to the input end of the commutator 51. The two sets of mold assemblies 7 are located at both ends of the upper surface of the support plate 54, respectively. Driven by the external servo motor, the gear 52 is rotated under the commutation drive of the commutator 51. Furthermore, through the meshing of gear 52 and rack 53, rack 53 is moved laterally. At the same time, guide rail 55 and slider 56 are slidably connected, providing good guidance and support for support plate 54, ensuring the stability of the lateral displacement of support plate 54. By automatically controlling the forward and reverse rotation of servo motor, support plate 54 can be moved back and forth left and right. To ensure the accuracy of the position of mold assembly 7, sensors can be set at both ends of support plate 54 to achieve precise positioning of the left and right displacement of support plate 54. Through this dual-station setting, when one set of mold assembly 7 is performing injection molding, another set of mold assembly 7 is being cleaned, and so on, ensuring that mold cleaning is carried out while the mold injection is continuous, greatly improving its injection efficiency.

[0033] Furthermore, it also includes a dual-outlet cylinder 6, which is fixedly connected to the upper surface of the first top plate 13. The lifting end of the dual-outlet cylinder 6 is fixedly connected to a sealing plate 62 through a positioning lug 61. The sealing plate 62 is slidably disposed inside the interlayer partition 12. Guide shafts slide through both the upper and lower ends of the sealing plate 62, and the guide shafts are fixedly connected to the frame 11 and the first top plate 13 respectively. Through this structure, it mainly works with the cleaning chamber cover 15 to seal the chamber, thereby preventing the splashing of waste debris when cleaning the mold assembly 7. The sealed structure completes the collection of waste debris. At the same time, a collection groove is opened at the bottom of the frame 11 to facilitate the diversion and collection of waste debris.

[0034] Working principle: When the right mold assembly 7 is placed directly below the pouring nozzle 21, the left mold assembly 7 is placed inside the cleaning chamber cover 15 on that side. At this time, the double-outlet cylinder 6 controls the sealing plate 62 to close, thereby completing the sealing and wrapping of the left mold assembly 7 with the cooperation of the cleaning chamber cover 15. Further, under the lifting control of the second cylinder 71, the upper mold 72 rises and separates. Thus, through the supply of high-pressure gas from the outside of the high-pressure pipe 3, and with the setting of the pressurizing nozzle 31, the waste on the surface of the upper mold 72 and the lower mold 73 is blown away. During the rising process of the upper mold 72, the brush rod 41 is inserted into the inside of the pouring hole. Driven by the high-speed rotation of the first motor 4, the brush rod 41 cleans the inner wall of the pouring hole, thereby achieving the cleaning of the upper mold 72 and the lower mold 73. The upper mold 72 and lower mold 73 are thoroughly cleaned, and the debris falling off during cleaning is collected below the frame 11. After cleaning, the upper mold 72 descends and docks with the lower mold 73. At this time, the right mold assembly 7 performs injection molding simultaneously. By lowering the first cylinder 2, the injection nozzle 21 is inserted into the injection hole of the right mold assembly 7 to complete the injection molding. After injection molding, both sealing plates 62 are opened. Then, under the control of the reciprocating assembly 5, the two sets of mold assemblies 7 move to the right simultaneously, allowing the right mold assembly 7 to enter the right cleaning chamber cover 15. After cooling, the upper mold 72 is opened to remove the mold and perform cleaning. At the same time, the left mold assembly 7 performs injection molding. This cycle is repeated to achieve efficient cleaning and injection molding of the device.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
