Description

Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a servo cabin forming mold. Background Art

[0002] The process has been applied by some enterprises in related fields such as automotive parts, wind power products, ships and yachts, and has partially or completely replaced the traditional hand lay-up process. RTM is a composite material production process that first places the reinforced fabric in a mold to form a certain shape, then injects the resin into the mold, impregnates the fiber and solidifies it. It is one of the main molding processes of FRP. Its biggest feature is low pollution, it is a closed mold operating system, and the designability and directionality of the finished product are enhanced.

[0003] For example, the authorization announcement number "CN216373408U" is named a servo cabin molding mold. Although it is injected into the molding cavity through the injection port through the semiconductor refrigerator and the cooling copper column, after the injection is completed, the semiconductor refrigerator is started to transfer the low temperature to the cooling copper column. The cooling copper column cools the outer mold and can automatically cool down, thereby speeding up the molding time and improving work efficiency. However, the existing servo cabin molding mold adopts the method of pulling out the inner mold after molding horizontally, and then it is convenient to demold and remove the molded servo cabin from the mold. However, when demolding the molded servo cabin, it is necessary to separate the inner mold first and then separate the servo cabin from the external inner mold before the servo cabin can be disassembled. This requires two push-to-separate structures to demold the finished product inside the mold, which not only consumes more time, but also prolongs the normal working time of the servo cabin to be molded next time, affecting the reduced work efficiency of the servo cabin molding mold.

[0004] At the same time, the existing servo cabin molding mold, since the outer mold and the inner mold are sleeved together, and then injection molding is carried out inside the middle molding cavity, the molding cavity on the side of the injection hole will be relatively full with the injected molding material, while the position inside the mold far away from the bottom of the injection hole requires the injection molded material to flow to the inside of the other side of the mold to achieve full filling. Moreover, the servo cabin product after molding is prone to bubbles or hollows on the side far away from the injection hole, while the side close to the bottom of the injection hole is lighter and has poorer quality, thereby reducing the quality of the molded product of the servo cabin molding mold. Utility Model Content

[0005] The utility model aims to solve the problems of low working efficiency and poor quality of formed products of a servo cabin forming mold, and proposes a servo cabin forming mold.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a servo cabin molding mold, comprising a chassis, a support frame and an outer mold, a fixed seat is fixedly installed above the chassis, a servo cabin rapid molding mold structure is provided on the top of the fixed seat, the servo cabin rapid molding mold structure comprises a hydraulic cylinder, an inner mold and a molding cavity, two of the hydraulic cylinders are fixedly installed on both sides above the fixed seat, a top plate is fixedly installed on the top of the two hydraulic cylinders, an inner mold is fixedly installed on the inner side of the top plate, a stripping plate is movably connected to the bottom end of the inner mold, the internal thread of the stripping plate is connected with a bolt, the top end of the bolt is threadedly connected to the lower end of the inner mold, and the molding cavity is fixedly opened inside the outer mold.

[0007] Preferably, the outer mold is fixedly mounted on the top of the fixing seat, the inner side of the outer mold is movably connected to the outside of the inner mold, the outer wall of the stripping plate is slidably connected to the inner wall of the outer mold, and the bottom of the top plate is movably connected to the top of the outer mold.

[0008] Preferably, an injection hole is fixedly installed on the inner side of the top plate, and the lower end of the injection hole is movably connected to the inner side of the molding cavity.

[0009] Preferably, the outer mold is provided with a cooling structure to accelerate molding;

[0010] The cooling and accelerating molding structure comprises a refrigeration box, a cold transport pipe and a cooling pipe;

[0011] The cold supply pipe is fixedly installed inside the outer mold, and both ends of the cold supply pipe are fixedly connected to refrigeration boxes. Two control valves are fixedly installed outside the cold supply pipe. The cooling pipe is fixedly opened inside the inner mold, and the outer side of the cooling pipe is arranged opposite to the inside of the molding cavity.

[0012] Preferably, an injection molding structure for uniformly reducing hollowing is provided above the support frame;

[0013] The injection molding uniform hollow reduction structure comprises an opening groove, a plate body and a motor;

[0014] The two motors are fixedly installed on the top of the support frame, the output shafts of the two motors are fixedly connected to two turntables, the outer walls of the two turntables are fixedly connected to multiple soft rods, the ends of the multiple soft rods are fixedly connected to impact heads, the two opening grooves are fixedly opened on the inner side of the fixing seat, the two plate bodies are fixedly installed on the outer wall of the outer mold, and the ends of the multiple impact heads are movably connected to one side of the plate body.

[0016] The utility model proposes a servo cabin molding mold, which has the beneficial effect of injecting molding material into the molding cavity between the outer mold and the inner mold through the injection hole. After the servo cabin inside the outer mold is shaped, the hydraulic cylinder pushes the top plate to lift upward. At this time, the inner mold pulls the demolding plate at the lower end to pull the molded servo cabin out of the outer mold. By utilizing the vertically set mold combination, rapid demolding and mold closing operations can be achieved, which saves the working time of the servo cabin molding mold and improves the working efficiency of the servo cabin molding mold.

[0017] When the injection molding material has just been poured into the molding cavity through the injection hole, the power is connected to start the motors on both sides. The turntable will drive multiple soft rods to rotate in the open grooves in turn. Each soft rod will drive the front impact head to hit the plate body. The impact force on the plate body will be transmitted to the inside of the outer mold. In this way, the injection molding material can be compacted inside the outer mold, reducing the generation of hollows and bubbles, and improving the product quality of the servo cabin molding mold.
