Abstract

The invention discloses a via hole hardware insert and plastic piece integrated blow molding mold and a using method thereof. According to the invention, the integral blow molding of the hardware insert and the plastic piece with the through hole is realized by arranging the insert auxiliary insert, and compared with the existing subsequent drilling assembly processing mode, the production efficiency is improved, the production cost is reduced, and the consistency of the assembly size and the connection strength of the hardware insert and the plastic piece are ensured.

Description

Via hole hardware insert and plastic part integrated blow molding mold and using method thereof

Technical Field

The invention relates to a through hole hardware insert and plastic part integrated blow molding die and a using method thereof, and belongs to the technical field of injection molding.

Background

In the automobile plastic part, one or more through-hole hardware inserts can be arranged on a plurality of tubular plastic parts so as to be convenient for assembling with an automobile body or other parts. Fig. 3 shows an air duct for an automobile filter system, which is designed with 2 via-hole hardware inserts for assembling and connecting with a fixed bracket on an automobile. When producing this kind of cavity working of plastics that have via hole five metals inserts, prior art is for first cavity working of plastics blow molding, and drilling installation via hole five metals inserts again. The production mode is low in production efficiency and high in production cost, and cannot guarantee the consistency of the assembly size and the connection strength of the hardware insert and the plastic part, so that the production mode is not sufficient.

Disclosure of Invention

In order to solve the defects, the invention provides a through hole hardware insert and plastic piece integrated blow molding die and a using method thereof, and the invention adopts the following technical scheme:

the utility model provides an integrative blow molding mould of via hole five metals inserts and working of plastics, blow molding mould includes the mould body, and the position that corresponds via hole five metals inserts on the die cavity of mould body installs the inserts fixing base, be provided with magnet in the inserts fixing base, magnetism is inhaled on the inserts fixing base and is installed the supplementary mold insert of inserts with the hole looks adaptation of via hole five metals inserts, and via hole five metals inserts cup joints and installs on the supplementary mold insert of inserts.

Furthermore, the insert fixing seat is installed on a cavity of the die body through magnetic attraction or through a groove formed in the die body.

The use method of the blow molding mold comprises the following steps: install the inserts fixing base on the die cavity of mould body, cup joint the via hole five metals inserts and install back magnetism is inhaled on the supplementary insert of inserts and is installed the inserts fixing base forms an organic whole with working of plastics and via hole five metals inserts blow molding through the blowing machine behind the mould body compound die, and the excision waste material is taken out after the die sinking the supplementary insert of inserts.

Compared with the prior art, the invention has the beneficial effects that: according to the invention, the integral blow molding of the hardware insert and the plastic piece with the through hole is realized by arranging the insert auxiliary insert, and compared with the existing subsequent drilling assembly processing mode, the production efficiency is improved, the production cost is reduced, and the consistency of the assembly size and the connection strength of the hardware insert and the plastic piece are ensured. Meanwhile, the arrangement of the insert auxiliary insert prevents the rubber material from flowing into the hole of the via-hole hardware insert, and the processing difficulty and time of subsequent processing are reduced.

Drawings

FIG. 1 is a schematic view of the mold structure of the present invention;

FIG. 2 is a schematic view of the assembly structure of the via hole hardware insert and the insert auxiliary insert of the present invention;

fig. 3 is a schematic view of an air duct structure in the prior art.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings.

Example (b):

referring to fig. 1-2, a via hole hardware insert and integrative blow molding mould of working of plastics, blow molding mould includes mould body 1, and the position that corresponds via hole hardware insert 2 on the die cavity of mould body 1 installs inserts fixing base 3, be provided with magnet 4 in the inserts fixing base 3, magnetism is inhaled on inserts fixing base 3 and is installed the supplementary mold insert 5 of inserts with the hole looks adaptation of via hole hardware insert 2, and via hole hardware insert 2 cup joints and installs on the supplementary mold insert 5 of inserts.

Further, the insert fixing seat 2 is installed on a cavity of the die body 1 by slotting on the die body 1.

The use method of the blow molding mold comprises the following steps: install inserts fixing base 3 on the die cavity of mould body 1, cup joint via hole five metals inserts 2 and install back magnetism is inhaled and is installed on the supplementary mold insert 5 of inserts insert 3, form an organic whole with working of plastics and the blow molding of via hole five metals inserts 2 through the blowing machine behind the 1 compound die of mould body, the excision waste material takes out after the die sinking the supplementary mold insert 5 of inserts can.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
