Abstract

The utility model discloses a spiral piece injection mold, a front mold insert and a rear mold insert are arranged between the front mold insert and the rear mold insert, the inserts adopt a split structure, so that spiral hardware is quickly fixed by the mold insert mold closing, the purpose of quick mold closing is achieved, and for different spiral hardware, the high-cost mold inserts are not required to be redesigned, only low-cost inserts are required to be replaced, and the manufacturing cost is saved; after the mold is opened, the mold insert is directly separated, the mold insert is not influenced by product back-off, a special ejection tool is not required to be configured, the mold insert is convenient and quick, and the injection molding efficiency and the injection molding quality are improved.

Description

Screw injection mold
Technical Field
The utility model belongs to injection mold specifically is a mould that relates to an injection moulding spiral piece.
Background
For the injection molding shaft piece containing spiral hardware, the front and the back of the product are both provided with the back-off, and the mold opening can not be formed after injection molding, so that the processing and assembly are difficult, and the manufacturing cost is higher.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an easy compound die, easy demoulding, low-cost spiral piece injection mold.
In order to solve the technical problem, the utility model discloses a technical scheme be: the utility model provides a screw injection mold, includes front mould benevolence and back mould benevolence, be provided with front mould mold insert and back mould mold insert between front mould benevolence and the back mould benevolence.
Further, the insert is of a split structure.
Further, the inserts are connected through a positioning pin.
Furthermore, guide pins are arranged in the front mold insert and the rear mold insert in a penetrating mode.
According to the technical scheme, due to the fact that the split type inserts are additionally arranged on the front mold core and the rear mold core, the spiral hardware is quickly fixed by the inserts in a mold closing mode, the purpose of quickly closing the mold is achieved, a high-cost mold core does not need to be redesigned for different spiral hardware, only the low-cost inserts need to be replaced, and manufacturing cost is saved; after the mold is opened, the mold insert is directly separated, the mold insert is not influenced by product back-off, a special ejection tool is not required to be configured, the mold insert is convenient and quick, and the injection molding efficiency and the injection molding quality are improved.
Drawings
Fig. 1 is a schematic structural diagram of a screw injection mold.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1, the screw injection mold mainly comprises a front mold core 1, a front mold insert 3, a rear mold insert 4 and a rear mold core 2.
A pair of front mold inserts 3 are embedded in a forming cavity of the front mold core 1, and the two front mold inserts 3 are used for accommodating spiral hardware 7 after being matched. The two front mold inserts 3 are fixed by front mold locating pins 4, and the front mold locating pins 4 transversely penetrate through the front mold inserts 3.
A pair of rear mold inserts 4 are embedded in a molding cavity 2.1 of the rear mold core 2, and the two rear mold inserts 4 are used for accommodating spiral hardware 7 after being closed. The two rear mold inserts 4 are fixed by a rear mold positioning pin 5, and the rear mold positioning pin 5 transversely penetrates through the rear mold inserts 4.
And an injection shaft part 8 containing spiral hardware 7 is formed between the front mold insert 3 and the rear mold insert 4 after mold closing.
A guide needle 6 penetrates between the front mold insert 3 and the rear mold insert 4, and the guide needle 6 vertically penetrates through the inserts.
The injection molding process of the screw injection mold comprises the following steps: firstly, hardware is fixed by an insert in an injection mold, and the hardware is placed in a mold inner core → mold closing → plastic plasticizing → injection into a cavity → molding cooling → mold opening ejection → finally taking out the insert.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
