Preferably, a button is arranged under the rear push plate.

Preferably, the base is provided with external guide pins at both ends of the transverse portion for positioning on the mould.

Preferably, a handle is mounted to a lateral portion of the base.

Preferably, the two ends of the transverse part of the base and the outer ends of the vertical part are respectively provided with a side flat seat.

Compared with the prior art, the invention has the beneficial effects that: by placing the Pin needle on the tool and inserting the Pin needle into the mold core of the mold through the tool, the invention eliminates the risk of scalding caused by manual direct injection of the Pin needle into the mold and the risk of deformation and damage to the Pin caused by asynchronous injection of the Pin needle into the mold.

Detailed Description

The invention is described in further detail below with reference to the drawings and the detailed description.

As shown in fig. 1 to 8, the embodiment provides a Pin fixture for in-mold insertion, which comprises a base 3, the cross section of the base 3 is T-shaped, a large insert 18 and a small insert 19 for accommodating Pin needle 1 and Pin needle 2 are embedded in the vertical part of the base 3, the large insert 18 is higher than the small insert 19, the two small inserts 18 and 19 form a stepped structure, two round-head pins 5 are mounted in the large insert 18, two flat-head pins 4 are mounted in the small insert 19, the heads of the round-head pins 5 are respectively used for positioning the positioning holes 101 and 201 at the Pin needle 1 and the Pin needle 2A end, the heads of the flat-head pins 4 are respectively used for positioning the positioning holes 102 and 202 at the Pin needle 1 and the Pin needle 2B end, the large insert 18 and the small insert 19 are provided with a rear cover plate 17 mounted under the base 3, the rear cover plate 17 is arranged under the rear cover plate 17, the round-head pins 5 and the flat-head pins 4 are fixedly arranged under the rear cover plate 10, the flat-head pins 10 are connected with the flat-head pins 10, the flat-head pins 10 are connected with the rear cover plate 10, the flat-head pins 10 can be fixedly arranged under the small push plate 13 and the small push plate 9, the small push plate 4 can be connected with the small push plate 13 and the small push plate 6, the small push plate 9 can be connected with the small push plate 13 and the small push plate 6 through the large push plate 8 and the small push plate 13, the small push plate 13 is connected with the large push plate 13 and the small push plate 13 can be fixedly arranged on the small push plate 13 and the small push plate 13 is connected with the small push plate 13. The push plate 10 is provided with a button 16, and the button 16 is convenient for a user to press quickly and accurately. The two ends of the transverse part of the base 3 are provided with outer guide pins 12 for positioning on the die 22, and the outer guide pins 12 are inserted in place in alignment with the die 22, so that the fixture is positioned accurately. A handle 15 is mounted on a transverse portion of the base 3 for carrying the tool.
