Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 4, 5 and 6, the cup extrusion molding tool disclosed in this embodiment includes a workbench 2 for inverting the vacuum cup liner 1, a molding mold 3 disposed above the workbench 2, and a power source 4 for driving the molding mold 3 to perform a longitudinal reciprocating linear motion. Wherein, the upper surface of workstation 2 is provided with the spacing seat 6 that supplies 5 joints of rim of a cup, and this spacing seat 6 is preferred to be bellied discoid, and the external diameter of spacing seat 6 equals or slightly is less than the internal diameter of rim of a cup 5 for spacing seat 6 can play more accurate positioning action. The periphery of the limiting seat 6 is provided with a lower forming surface 8 for pressing and forming the curling edge 7 in a surrounding way, the cross section of the lower forming surface 8 is preferably in an inward concave arc shape, and the section of the lower end of the lower forming surface is horizontally arranged; the shaping die 3's downside is seted up and is adapted to the shaping chamber 9 of thermos cup inner bag 1 external shape, and the last port of shaping chamber 9 upwards encircles and sets up the fashioned shaping annular 11 that supplies base 10, and the lateral wall of this shaping annular 11 is vertical setting, and its cross section size equals or slightly is greater than the wall thickness of thermos cup inner bag 1. The lower mouth of the forming cavity 9 is provided with an upper forming surface 12, the upper forming surface 12 preferably being in the shape of an outwardly protruding arc, the lower end section of which is arranged horizontally to form a fit with the lower forming surface 8. The pressing surface of the forming die 3 is provided with a cutting knife 13 in a surrounding way at the upper forming surface 12, the edge surface of the cutting knife 13 is arranged downwards, namely, the cutting knife 13 is arranged in a ring shape, and the redundant part of the turned edge 7 can be cut off at one time. The power source 4 is a cylinder, an oil cylinder or a hydraulic press connected to the forming mold 3, and in this embodiment, the connection manner between the power source 4 and the forming mold 3 belongs to common knowledge in the art, and is not described herein.

Further, the up end downwardly extending of one-tenth die cavity 9 has guide block 14, and this guide block 14 is the circular truncated cone form, and its and the up end coaxial arrangement of one-tenth die cavity 9, and the less one end of circular truncated cone form bore sets up downwards for forming die 3 is pushing down the in-process, and the bottom edge of thermos cup inner bag 1 can enter into to inside the shaping annular 11 more easily.

The specific working process is as follows:

firstly, inverting (namely, a cup opening 5 faces downwards) a vacuum cup liner 1 to be processed shown in fig. 2 on a workbench 2, so that the cup opening 5 can be buckled on a limiting seat 6, and meanwhile, an inclined turned edge 7 can be initially abutted against the horizontal part of a lower forming surface 8 to complete the positioning of the vacuum cup liner 1;

step two, starting the power source 4 to drive the forming mold 3 to press downwards, wherein the forming cavity 9 on the forming mold 3 is preferentially wrapped on the outer wall of the vacuum cup liner 1, then the forming mold 3 continues to move downwards, and the guide block 14 firstly enters the inner cavity 15 of the vacuum cup liner 1; under the guiding action of the outer circular conical surface of the guide block 14, the side wall of the bottom of the vacuum cup liner 1 gradually enters the forming ring groove 11 and deforms under the compression of the forming ring groove 11 to form a bottom edge 10 until the bottom edge of the vacuum cup liner 1 abuts against the bottom of the forming ring groove 11;

after the bottom edge of the vacuum cup liner 1 abuts against the bottom of the forming ring groove 11, the vacuum cup liner 1 continuously moves downwards under the compression of the forming mold 3, so that the turned edge 7 at the position of the cup opening 5 can gradually tend to be horizontal under the extrusion of the lower forming surface 8 to form a structure shown in fig. 3, and meanwhile, the cutting knife 13 positioned below the forming mold 3 also gradually moves downwards;

step four, when the forming die 3 moves downwards and the upper forming surface 12 abuts against the upper end surface of the curled edge 7, the cutting knife 13 can cut off the redundant part of the curled edge 7 to form the product structure shown in fig. 1;

and step five, the power source 4 drives the forming die 3 to move upwards to be away from the workbench 2, and then the processed vacuum cup liner 1 is taken down from the limiting seat 6.

And repeating the steps from one to five.

In this embodiment, the operation control of the power source 4 may be implemented by a PLC built-in program or an equivalent analog circuit, which belongs to the common general knowledge in the art and is not described herein.
