Abstract
The utility model provides a kind of mould with anticreep metal insert, comprises dynamic model and the cover half suitable with dynamic model, is provided with slide block in described cover half, be provided with the pin suitable with it in described slide block; One end and the slide block of described pin are connected, and the other end of pin is provided with the metal insert be connected with its threaded engagement; Described metal insert comprises boss and cylinder table integrated with it, and the both ends of the surface of described metal insert are equipped with chamfering.The built-in fitting adopting the utility model to produce is by boss restriction metal insert axial rotation; By the chamfering restriction metal insert axial float on boss and boss, thus prevent metal insert from use rotating and coming off.
Description
Technical field
The utility model belongs to plastic products production mould field, especially relates to a kind of mould with anticreep metal insert.
Background technology
In the bolt installation place of plastic products, for ensureing bonding strength, the general form of metal insert that adopts processes, and metal insert is sleeve-shaped, and inner surface is threaded to be installed for bolt.Metal insert is directly embedded in plastic products inside by extruding or injection moulding.But through using for a long time, plastic products creep can occur, and pretightning force diminishes, loosening or coming off easily appears in metal insert, affects the service life of plastic products.
At present, generally improve problems by modified node method, the method such as pretightning force and increase metal insert outer surface roughness that strengthens, but often there will be following problem in actual use: one is that modified node method is complicated, and production cost is increased; Two is thoroughly can not solve metal insert to loosen or the problem that comes off, and has just delayed the time that metal insert occurs to loosen and come off.
Summary of the invention
Problem to be solved in the utility model prevents loosening or coming off of metal insert, provides a kind of structure simply with the mould of anticreep metal insert, realize metal insert and be connected with the high strength of plastic products.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of mould with anticreep metal insert, comprises dynamic model and the cover half suitable with dynamic model, is provided with slide block in described cover half, be provided with the pin suitable with it in described slide block; One end and the slide block of described pin are connected, and the other end of pin is provided with the metal insert be connected with its threaded engagement; Described metal insert comprises boss and cylinder table integrated with it, and the both ends of the surface of described metal insert are equipped with chamfering.
Further, described pin one end is provided with external screw thread, and the diameter of non-threaded section of pin equals the external diameter of thread segment.
Further, injection molding cavity is provided with between described metal insert and slide block.
Preferably, described chamfering is 45 °.
Preferably, described boss is hexagonal boss.
The advantage that the utility model has and good effect are: the built-in fitting adopting the utility model to produce is by boss restriction metal insert axial rotation; By the chamfering restriction metal insert axial float on boss and boss, thus prevent metal insert from use rotating and coming off.

Fig. 2 is the structural representation of metal insert in the utility model.
In figure:
1-slide block, 2-pin, 3-injection molding cavity, 4-metal insert, 5-chamfering, 6-boss, 7-cylinder table.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
A kind of mould with anticreep metal insert as shown in Fig. 1 to 2, comprises dynamic model and the cover half suitable with dynamic model, is provided with slide block 1 in described cover half, is provided with the pin 2 suitable with it in described slide block 1; One end and the slide block 1 of described pin 2 are connected, and the other end of pin 2 is provided with the metal insert 4 be connected with its threaded engagement; Described metal insert 4 comprises boss 6 and cylinder table integrated with it 7; The both ends of the surface of described metal insert 4 are equipped with chamfering 5.
Described pin 2 one end is provided with external screw thread, and the diameter of non-threaded section of pin 2 equals the external diameter of thread segment.
Preferably, described chamfering is 45 °, and boss 6 and chamfering 5 can prevent metal insert play vertically.
Preferably, described boss is hexagonal boss, and metal insert 4 can be prevented around axial rotation.
Injection molding cavity 3 is provided with between described metal insert 4 and slide block 1.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
