Description

Technical Field

[0001] This utility model relates to the field of blow molding production, specifically a tooling for leak testing and chamfering of blow molded products. Background Technology

[0002] Blow molding is a plastic processing method that involves making a preform from thermoplastic plastic, then inflating it with compressed air to make it fit tightly against the inner wall of a mold. After cooling, it forms a hollow product. Based on the preform making method, blow molding is divided into extrusion blow molding and injection blow molding.

[0003] In practical use by those skilled in the art, the testing and processing work of existing blow molding equipment is usually carried out separately. This requires more manpower and equipment in the production process, resulting in relatively low production efficiency. Therefore, a leak detection and chamfering machine tooling for blow molded products is proposed to address the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies and solve the problem that testing and processing in blow molding equipment are usually carried out separately, which requires more manpower and equipment during production and results in relatively low production efficiency, this utility model proposes a leak detection and chamfering machine fixture for blow-molded products.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A leak detection and chamfering machine fixture for blow-molded products, comprising a frame, a control cabinet fixedly connected inside the frame, a cylinder A on one side of the frame, a pressure rod rotatably connected above the frame, the output end of cylinder A fixedly connected to one end of the pressure rod, a plastic part on the top of the frame, an air inlet on the plastic part, a cylinder D fixedly connected to the top of the frame, an air pipe connection port on the output end of cylinder D, and a rubber plug connected to one side of the air pipe connection port. A cylinder B is fixedly connected to the top of the frame, and a cutter is fixedly connected to the output end of cylinder B. A cylinder C is fixedly connected to the top of the frame, and a servo motor is fixedly connected to the output end of cylinder C. A chamfering blade is fixedly connected to the output end of the servo motor. A precision airtightness testing device is fixedly connected to the top of the frame. Multiple workstations are set on the frame. The cylinder A, pressure rod, plastic parts, cylinder D, air pipe connector, rubber plug, cylinder B, cutter, cylinder C, servo motor, and chamfering blade are all set according to the number of workstations. The precision airtightness testing device is connected to multiple workstations.

[0006] Preferably, the top of the frame has a waste outlet.

[0007] Preferably, a protective cover is fixedly connected to the top of the frame, and the protective cover is located above the plastic part.

[0008] Preferably, a fastener is fixedly connected to the top of the frame, and the plastic part is connected to the frame through the fastener.

[0009] Preferably, a start switch is fixedly connected to the top of the frame, and the start switch is electrically connected to the control cabinet.

[0010] Preferably, the plastic part is blow-molded to form a convex shape.

[0011] The advantages of this utility model are:

[0012] 1. In this utility model, the operator places the plastic part into the fixing part, turns on the start switch, and cylinder A presses down the pressure rod to firmly fix the product. Then, cylinder D, with its air pipe connection, presses down on the air inlet to maintain a sealed state. A precision airtightness testing device then pressurizes the product and holds the pressure for a set number of seconds. When the pressure test reaches the set number of seconds, an alarm displays "OK" indicating success. If the air pressure test fails, an alarm displays "N," the pressure holding stops, cylinder A and the pressure rod reset, and the product is removed and placed in the defective product category. For products that pass the air pressure test, cylinder D resets and the rubber plug returns to its original position. Then, cylinder B starts working, pushing the cutter forward to cut off the protrusion on the product and returns to its original position. The servo motor is then started, and cylinder C starts working, pushing the servo motor forward. The chamfering cutter mounted on the servo motor rotates at high speed to process the protrusion on the product. After processing, the cutter returns to its original position and stops rotating. Then, cylinder A is started to lift the pressure rod, and the operator removes the product and places it in the qualified product frame. This tooling system performs testing and processing in a single station, reducing manpower and equipment requirements and improving production efficiency.

[0013] 2. This utility model features a multi-station setup, and one precision airtightness testing device can simultaneously test multiple stations, which directly increases the production efficiency of the device and saves production costs. Attached Figure Description
