Abstract
The utility model relates to a shell threaded insert structure, which is subjected to reaction injection molding (RIM). The structure comprises the shell threaded insert structure which comprises an insert and a threaded hole formed on the surface of the insert. A pin for placing threads in advance can be machined at a threaded position in the conventional molding die; before a shell is molded, the die is opened, the pin is put into the threaded insert; then the die is closed; and the shell is machined. Compared with the conventional machining product, the shell threaded insert structure does not need glue and repair, so the labor cost is relatively low; the stability of the shell is high; the torque of the machined shell is high; and the threads cannot drop out.
Description
Technical field
The utility model relates to a kind of one threaded insert, particularly relates to a kind of do not need glue and repairing, and cost of labor is lower, and product stability is high, and the torsion after the processing is high, and screw thread does not have the housing threaded insert that drops out.
Background technique
The RIM product is a kind of housing processing technology, and the screw that the most cases lower shell body all need be installed assembling carries out the housing assembling.
Existing technology is our new mould, and a molding product, product are repaired the processing rear end, with glue with repair packing and place screw thread.This way is manual operations because of back-end processing entirely, and cost of labor is higher, and product stability is poor, and the torsion after the processing is not high yet, and screw thread is prone to drop out.
The model utility content
To the problems referred to above, the main purpose of the utility model is to provide a kind of do not need glue and repairing, and cost of labor is lower, and product stability is high, and the torsion after the processing is high, and screw thread does not have the housing threaded insert that drops out.
The utility model solves above-mentioned technical problem through following technical proposals: a kind of housing threaded insert structure, said structure comprise inserts and open the tapped hole on insert surface.
In the practical implementation example of the utility model, the pin of screw thread is put in the screw position processing in shaping die in advance, and said inserts is put into said pin.
The positive progressive effect of the utility model is: the housing threaded insert that the utility model provides has the following advantages: the screw position processing of the utility model in our existing shaping die can be put the pin of screw thread in advance; Before the moulding; Open mould; Threaded insert is put into pin, and closing molding carries out the housing processing again.With existing processed product relatively, do not need glue and repairing, cost of labor is lower, product stability is high, the torsion after the processing is high, screw thread does not have and drops out.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technological scheme of the utility model.
Fig. 1 is the structural representation of the utility model, and is as shown in the figure, and the utility model comprises inserts 1 and opens at inserts 1 lip-deep tapped hole 2.The pin of screw thread is put in screw position processing in shaping die in advance, and inserts 1 is put into said pin.
The product structure and the implementation method of the utility model are following:
Method is: the screw position processing in our existing shaping die can be put the pin of screw thread in advance, before the moulding, opens mould, and threaded insert is put into pin, and closing molding carries out the housing processing again.
With existing processed product relatively, do not need glue and repairing, cost of labor is lower, product stability is high, the torsion after the processing is high, screw thread does not have and drops out.
More than show and described basic principle of the utility model and the advantage of major character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications; These variations and improvement all fall in the utility model scope that requires protection, and the utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (2)
1. housing threaded insert structure, it is characterized in that: said structure comprises inserts (1) and opens at the lip-deep tapped hole of inserts (1) (2).
