Description

Technical Field

[0001] This utility model relates to the field of plastic injection molded pipe fitting production technology, specifically to an injection molded pipe fitting material head separation device. Background Technology

[0002] Injection molded pipe fittings are plastic pipe connectors manufactured using the injection molding process. Common types include PERT and PPR injection molded pipe fittings, which are widely used in water supply and drainage, gas, chemical, and electrical industries. During production, a single mold can produce multiple injection molded pipe fittings simultaneously. These fittings are attached to the sprue and need to be removed in subsequent processing stages.

[0003] In existing technologies, there are two main methods for removing sprue: shearing and high-frequency vibration separation. Shearing involves directly separating the sprue from the injection molded part using a cutting tool; high-frequency vibration separates the sprue and the injection molded part automatically by using ultrasonic vibration to vibrate the mold. Relatively speaking, high-frequency vibration separation is much more efficient than shearing separation.

[0004] In the existing technology, there is no ultrasonic vibration equipment specifically designed for separating the sprue heads of injection molded tubes. Instead, other ultrasonic vibration equipment is used for separation. Most ultrasonic vibration equipment consists of only one vibration mold. During use, a clamp is used to hold a batch of injection molded tubes on the vibration mold, and then another rod-shaped tool is used to press down on the injection molded tubes or sprue heads on the vibration mold. Each time, only the sprue heads and injection molded tubes at the corresponding position and nearby positions of the vibration mold can be separated. A batch of injection molded tubes needs to be adjusted and the operation repeated multiple times to separate the entire batch of sprue heads and injection molded tubes, which is quite inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a material head separation device for injection molded pipe fittings. This device solves the problem that the lack of specialized ultrasonic vibration equipment for separating material heads in existing technologies leads to the inconvenience of using ordinary ultrasonic vibration equipment to separate material heads and injection molded pipe fittings.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A material head separation device for injection molded pipe fittings includes a fixed housing with an open top, an inclined mounting bracket fixed to the top of the fixed housing, a downward push rod mounted on the mounting bracket, an inclined pressure plate disposed below the mounting bracket, the pressure plate being fixed to the lower end of the piston rod of the downward push rod, and a guide post vertically and movably inserted into the mounting bracket being fixed to the top of the pressure plate.

[0008] An inclined baffle is provided near the top inside the fixed housing. A stop bar is fixed to the top of the downward inclined side of the baffle. Through slots are distributed in a matrix on the baffle. A fixed plate is fixed at an incline inside the fixed housing. A transducer is installed on the fixed plate directly opposite the through slot. An amplitude transformer and a vibration mold are fixed to the transducer in sequence. The upper end of the vibration mold is inserted into the through slot.

[0009] The surface of the vibration mold is fitted with a partition plate fixed inside the fixed housing and located between the baffle and the fixed plate. The partition plate is provided with a clearance groove corresponding to the vibration mold. A hopper is provided on one side of the fixed housing at the position corresponding to the fixed plate. An ultrasonic electronic box electrically connected to the transducer is provided inside the fixed housing.

[0010] Preferably, the fixed housing is a vertical box structure, with a storage cabinet located at the bottom inside the fixed housing, and the ultrasonic electronic box located above the storage cabinet. Cabinet doors are hinged to the fixed housing at the positions corresponding to the storage cabinet, the ultrasonic electronic box, and the transducer.

[0011] Preferably, the mounting bracket and the baffle are disposed on opposite sides of the fixed chassis, and the mounting bracket, the pressure plate and the partition are parallel to each other.

[0012] Preferably, there are multiple vibrating molds, and a pressure block is provided at the bottom of the pressure plate corresponding to the position of the vibrating mold.

[0013] Preferably, the distance between the through groove and the vibrating mold is greater than the distance between the repositioning groove and the vibrating mold.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention addresses the shape of a single sheet of injection-molded tubing by using an inclined baffle and pressure plate. Multiple vibrating molds are installed below the baffle. A single sheet of injection-molded tubing is placed directly on the baffle, and the pressure plate and pressure block simultaneously press down on the multiple vibrating molds, achieving separation of the sprue and the injection-molded tubing over a large area. A single sheet of injection-molded tubing can be separated with just one pressing and vibration operation, making the operation simpler and the separation faster, significantly improving production efficiency and bringing convenience to the production of injection-molded tubing. It solves the problem in the prior art where the lack of a dedicated ultrasonic vibration device for separating the sprue of injection-molded tubing leads to the inconvenience of using ordinary ultrasonic vibration equipment to separate the sprue and injection-molded tubing.
