Preferably, the weighing profiling table comprises an electronic scale body and a profiling seat fixed at the upper end of the electronic scale body, and the weighing limiting part is arranged on the upper end surface of the profiling seat; the electronic scale body is also connected with an electronic scale display screen for displaying weighing data.

Preferably, a photoelectric detection sensor is further fixedly mounted on the upper end face of the pushing table.

Preferably, each weighing profiling table and each pushing table correspond to two pushing cylinders, and the two pushing cylinders are respectively arranged at the oblique diagonal positions of the pushing table.

Compared with the prior art, the utility model has the advantages that:

the device can realize accurate weighing detection of injection molding end products, is suitable for products with multiple specifications, shortens the subsequent picking processing time and improves the production efficiency; a plurality of products can be weighed, labor force is released, the load of workers is reduced, and the cost of enterprises is reduced; the structural design is simple and reasonable, and the weighing precision can be guaranteed.

Drawings

The utility model is further described with reference to the following figures and examples:

FIG. 1 is a schematic structural diagram of an end product weighing apparatus of an injection molding machine according to the present invention;

fig. 2 is a schematic structural diagram of an end product weighing apparatus of an injection molding machine in a local application scenario.

Wherein: 1. the electronic scale comprises a workbench, 2, a weighing profiling table, 21, an electronic scale body, 22, a profiling seat, 23, an electronic scale display screen, 24, a weighing limiting part, 3, a pushing table, 31, a placing limiting part, 32, a photoelectric detection sensor, 4, a pushing cylinder, 5 and a slide way.

Detailed Description

The present invention will be further described in detail with reference to the following specific examples:

as shown in fig. 1, the weighing device for the end product of the injection molding machine comprises a workbench 1, a weighing profiling table 2 installed above the workbench 1, a pushing table 3 arranged around the outer contour of the weighing profiling table 2, and a pushing cylinder 4 driving the pushing table 3 to lift.

The weighing profiling platform 2 comprises an electronic scale body 21 and a profiling seat 22 fixed at the upper end of the electronic scale body 21; the electronic scale body 21 is further connected with an electronic scale display screen 23 for displaying weighing data, and a weighing limiting part 24 is arranged on the upper end face of the profiling seat 22 and used for limiting a product above the weighing limiting part.
