Description

Technical Field

[0001] This invention belongs to the field of automotive engine bracket processing technology, and particularly relates to a processing device and processing method for automotive engine brackets. Background Technology

[0002] Engine mounts, also known as engine mounts or engine suspensions, are used to fix and support the engine and transmission. They rely on rubber and hydraulic structures to isolate vibration, reduce noise, and buffer torque. The engine mounts have built-in rubber or hydraulic components to absorb high-frequency vibrations from the engine (idling, combustion, torque impact), reducing the transmission to the vehicle body and cabin, and lowering NVH (vibration / noise / sound roughness).

[0003] The engine mount mainly uses rubber buffer bushings as the main shock absorption structure. Two sets of fixing components are fixed to the vehicle body and the engine respectively. The fixing components are flexibly connected by rubber buffer bushings. In the existing technology, one set of fixing components in the engine mount adopts a complex irregular structure. In order to enhance structural stability, the irregular structure fixing components are mostly processed by one-piece molding technology. When assembling the rubber buffer bushing with the other set of fixing components, a special injection cavity is required to accommodate the irregular structure fixing component. However, the complex size and structure of the injection cavity and the abnormal shape of the injection space can easily affect the pressure stability of the rubber buffer bushing during the injection process, which can easily lead to insufficient strength of the rubber buffer bushing. Summary of the Invention

[0004] This invention provides a processing device for automotive engine brackets, aiming to solve the problem that the current irregular-shaped engine brackets, due to their abnormal injection molding space shape, easily affect the pressure stability of the rubber buffer bushing during injection molding, and easily cause insufficient strength of the rubber buffer bushing.

[0014] Preferably, the connecting end face of the middle mold and the first side mold is a first plane, and the connecting end face of the middle mold and the second side mold is a second plane. The first plane and the second plane respectively penetrate the molding cavity and the end seat receiving cavity of different injection cavities.

[0015] Preferably, the connecting rod receiving cavity is provided with an assembly groove, the assembly groove is provided with a first blocking element, and the top mold unit is provided with a second blocking element at a position corresponding to the assembly groove.

[0019] Preferably, the second blocking element includes a stepped mounting base and a sealing strip, the notch of the mounting base facing the molding cavity, and the sealing strip being assembled at the notch of the mounting base.

[0020] Preferably, the sealing strip and the U-shaped seal form a through groove with an irregular structure, and during the glue injection process, the sealing strip and the U-shaped seal isolate the connection between the molding cavity and the end seat receiving cavity.

[0021] The present invention also provides a method for processing an automobile engine bracket, wherein the processing method employs an automobile engine bracket processing device as described above.

[0022] The processing method of the automobile engine bracket includes:

[0048] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0049] This invention provides a processing device for an automobile engine bracket, such as... Figures 1-10 As shown, the processing device for an automobile engine bracket includes:

[0050] A processing table 100 includes an injection molding frame 110 and a base 120. The injection molding frame 110 is suspended above the base 120 to form a processing area. The injection molding frame 110 has a heating chamber, an injection molded part, and corresponding equipment structures inside. The injection molding frame 110 is basically the same as existing injection molding equipment. An injection mold head that can move up and down is provided below the injection molding frame 110. The injection mold head can be held against the mold located in the processing area by the lifting structure. The processing table 100 is mainly based on existing technology. For detailed structure, please refer to existing technology. This application will not describe it in detail.

[0051] Mold 200 is mounted on a sliding bracket provided on base 120. Mold 200 includes a top mold unit 210, a middle mold unit 220, and a bottom mold unit 230 stacked sequentially. The bottom mold unit 230 is directly assembled on the sliding bracket, which adopts a support plate and a guide rail for the support plate. The sliding bracket can slide and pull the mold 200 to the processing area. After the mold 200 arrives at the processing area, the injection mold head is held against the mold 200 by a lifting structure. The docking connection method of the top mold unit 210, the middle mold unit 220, and the bottom mold unit 230 refers to the prior art and will not be described in detail in this application.

[0052] The intermediate module unit 220 includes:

[0053] The connecting rod receiving cavity 203 is disposed on the intermediate mold 222;

[0054] The first side mold 221 and the second side mold 223 are hinged to both ends of the middle mold 222. The first side mold 221 and the second side mold 223 are flipped upwards away from the middle mold 222. When the top mold unit 210 is pressed down, the first side mold 221 and the second side mold 223 can only continue to resist the sides of the middle mold 222 under the pressure.

[0055] The middle mold 222, the first side mold 221, and the second side mold 223 form an integral structure and are set between the top mold unit 210 and the bottom mold unit 230.

[0056] The intermediate mold unit 220 is provided with injection cavities for processing automotive engine brackets. These injection cavities include a molding cavity 202 for processing rubber buffer bushings, a connecting rod receiving cavity 203, and an end seat receiving cavity 204. The automotive engine bracket mainly includes a connecting rod 410, a first connecting seat 420, a second connecting seat 430, and a rubber buffer bushing 440. The connecting rod 410 has an outer ring at its end away from the first connecting seat 420. This outer ring is nested within the outer edge of the second connecting seat 430 via the rubber buffer bushing 440. Multiple sets of injection cavities are provided, and adjacent cavities face opposite directions. Since the first connecting seat 420 and the second connecting seat 430 have different sizes, staggered arrangement with different orientations maximizes space utilization. The end seat receiving cavity 204 is structurally compatible with the first connecting seat 420.

[0057] The outer ring of the rubber buffer bushing of the car engine bracket needs to be placed in the molding cavity 202. The connecting rod receiving cavity 203 is provided with a first blocking element 310 and a second blocking element 320. The first blocking element 310 and the second receiving cavity 302 form a through slot that is adapted to the cross-section of the connecting rod 410 of the car engine bracket.

[0058] In this embodiment, the connecting rod receiving cavity 203 and the end seat receiving cavity 204 are respectively used to place the connecting rod 410 of the automobile engine bracket and the first connecting seat 420 that does not require processing of the rubber buffer bushing. The first blocking member 310 and the second blocking member 320 use high-temperature resistant silicone material as the main sealing components. The first blocking member 310 and the second blocking member 320 form a through slot for the connecting rod 410 to pass through, while blocking the communication between the molding cavity 202 and the end seat receiving cavity 204. Through the blocking effect, the rubber inside the molding cavity 202 cannot leak from the gap between the top mold unit 210 and the middle mold unit 220 and the gap between the connecting rod 410 and the first blocking member 310 and the second blocking member 320, thus maintaining the pressure stability of the molding cavity 202 during the injection molding process and avoiding pressure loss from affecting the structural strength of the rubber buffer bushing.

[0059] In a preferred embodiment of this invention, the connecting end face of the middle mold 222 and the first side mold 221 is a first plane, and the connecting end face of the middle mold 222 and the second side mold 223 is a second plane. The first plane and the second plane respectively penetrate the molding cavity 202 and the end seat receiving cavity 204 of different injection cavities. That is, after the second side mold 223 and the first side mold 221 are fitted and connected with the middle mold 222, the molding cavity 202 or the end seat receiving cavity 204 is formed.

[0060] In a preferred embodiment of this invention, the connecting rod receiving cavity 203 is provided with an assembly groove 201, the assembly groove 201 is provided with a first blocking element 310, and the top mold unit 210 is provided with a second blocking element 320 at a position corresponding to the assembly groove 201.

[0061] The first blocking member 310 includes a U-shaped frame 311 and a U-shaped seal 312 made of high-temperature resistant silicone; a first receiving cavity 301 is formed at the center of the inner edge of the U-shaped frame 311, and a second receiving cavity 302 is formed at the center of the inner edge of the U-shaped seal 312.

[0062] The U-shaped frame 311 has an embedded groove on its end face facing the molding cavity 202. The U-shaped seal 312 is engaged in the groove on the U-shaped frame 311. The U-shaped frame 311 is assembled in the assembly slot 201 by bolts. The U-shaped frame 311 has a slot. The outer edge of the U-shaped seal 312 has a protrusion that matches the slot. The protrusion is assembled in the slot to complete the limiting assembly, so that the end face of the U-shaped seal 312 away from the U-shaped frame 311 faces the molding cavity 202.

[0063] In this embodiment, the assembly groove 201 is recessed inward from the three end faces of the connecting rod receiving cavity 203 to form a U-shaped groove. The U-shaped frame 311 is embedded in the U-shaped groove as a whole. The top of the U-shaped frame 311 needs to be flush with the contact end faces of the top mold unit 210 and the middle mold unit 220. It should be noted that part of the structure of the U-shaped seal 312 extends into the U-shaped groove, while part of the structure extends beyond the side wall of the U-shaped frame 311. That is, the size of the second receiving cavity 302 is smaller than the size of the first receiving cavity 301, and the inner edge structure of the second receiving cavity 302 is adapted to the cross-sectional structure of the connecting rod 410.

[0064] The second blocking component 320 includes a stepped mounting base 321 and a sealing strip 322. The notch of the mounting base 321 faces the molding cavity 202. The sealing strip 322 can be assembled at the notch of the mounting base 321 by bolt fixing. The sealing strip 322 is also made of high temperature resistant silicone. The second blocking component 320 mainly cooperates with the top mold unit 210 to seal the gap between the top mold unit 210 and the middle mold unit 220.

[0065] The top mold unit 210 adopts a male mold structure with a protrusion embedded in the injection cavity of the middle mold unit 220. The second blocking component 320 will block the connection between the molding cavity 202 and the end seat receiving cavity 204 at the connecting rod 410.

[0066] In a preferred embodiment of this invention, the top mold unit 210 is provided with a glue flow channel and a flow divider groove adapted to the glue injection port of the mold head on the end face away from the middle mold unit 220, and the mold head is in contact with the end face of the top mold unit 210 away from the middle mold unit 220.

[0067] The top mold unit 210 is also provided with several sets of injection holes 205 that communicate with the molding cavity 202. The injection holes 205 penetrate the top mold unit 210. The glue flow channel is connected to different injection holes 205. After the rubber is filled with oil and injected into the distribution channel by the injection molding equipment, the distribution channel will disperse and transport the rubber along the glue flow channel.

[0068] In a preferred embodiment of this invention, the side of the second blocking member 320 where the sealing strip 322 is located is the injection side. The portion of the top mold unit 210 located on the injection side is provided with an overflow groove 206. Excess glue generated during the injection process will enter the overflow groove 206.

[0069] In this embodiment, the overflow groove 206 needs to be set on the side of the first blocking member 310 in the top mold unit 210 near the molding cavity 202;

[0070] This invention provides a method for processing an automotive engine bracket, wherein the processing method employs an automotive engine bracket processing device as described above;

[0071] The processing method of the automobile engine bracket includes:

[0072] Step 1: Preheat the rubber to prepare for the process, and pull the mold 200 out of the processing area to prepare for the installation of the car engine bracket.

[0073] Step 2: Remove the top mold unit 210 from above the middle mold unit 220, and rotate the first side mold 221 and the second side mold 223 away from the middle mold 222. Place several sets of car engine brackets in the injection cavity according to different orientations. It is necessary to check whether the first blocking part 310 is completely engaged with the connecting rod 410.

[0074] Step 3: Push the first side mold 221 and the second side mold 223 back to both sides of the middle mold 222. The first side mold 221 and the second side mold 223 will cooperate with the middle mold 222 to form the molding cavity 202 and the end seat receiving cavity 204.

[0075] Step 3: The molding cavity 202 is provided with a support column for supporting the second connecting seat 430. The second connecting seat 430 is assembled onto the support column. The technical principle of the support column is basically the same as that of the existing support mold. It should be noted that a corresponding mold for forming the auxiliary rubber buffer bushing will also be placed in the molding cavity 202. At the same time, a corresponding module structure will also be set on the top mold unit 210 to assist in forming a rubber buffer bushing of a specific shape. The support column and the mold are usually directly fixed on the bottom mold unit 230. The specific shape is customized according to the structure of the automobile engine bracket.

[0076] Step 4: The top mold unit 210 is pressed onto the middle mold unit 220. It is important to ensure that the male mold portion of the top mold unit 210 is embedded into the injection cavity of the middle mold unit 220. Then, the mold 200 is pushed back into the processing area.

[0077] Step 5: Press the injection mold head on the injection molding stand 110 onto the top mold unit 210 for injection molding, and then perform corresponding processing such as injection pressure holding to form a rubber buffer bushing.

[0078] Step 6: Raise the injection mold head and remove the mold 200 from the processing area. Then, manually lift and separate the top mold unit 210. Next, flip the first side mold 221 and the second side mold 223 upwards to separate them from the middle mold 222. Remove the car engine bracket and trim the edges.
