Abstract
The utility model discloses an injection mold with internal thread core-pulling mechanism, the injection mold with internal thread core-pulling mechanism comprises a fixed mold, a flexible mold, a subplate and a knockout plate, the later rim of the knockout plate is located at the bottom surface area along the projection of the parting direction, a molding insert is embedded and installed on the flexible mold, a connecting push rod provided with circular-arc-shaped bottom portion is fixedly disposed on the bottom portion of the molding insert, the connecting push rod passes through the flexible mold and the circular-arc-shaped bottom portion withstands the knockout plate simultaneously. The injection mold with internal thread core-pulling mechanism adopts the combination design of internally inlaid molding insert and the push rod ejection, realizes the advanced resetting by a resetting spring. The injection mold with internal thread core-pulling mechanism has the advantages of being simple in structure, less in knock-down parts, low in manufacturing cost and high in efficiency.
Description
Technical field
The utility model relates to the injection mold technical field, especially a kind of injection mold with inner threaded core-pulling mechanism.
Background technology
In known technical field, a lot of plastic fastening goods all have internal thread, generally inner threaded core-pulling is one of most thorny issue in injection mold, the equal more complicated of core-pulling mechanism that arranges, as everyone knows, mechanism is more complicated, and manufacturing processing is more difficult, and the stability of working simultaneously also reduces greatly.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of simple in structure, make the injection mold of inner threaded core-pulling mechanism easy to process.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of injection mold with inner threaded core-pulling mechanism, comprise solid plate, moving platen, backing plate and push pedal, the lateral edges of described push pedal is in the base surface area that is positioned at backing plate along the projection on minute mould direction, in described moving platen embedding moulding being installed inserts, be installed with the connection push rod with circular arc-shaped bottom portion in the bottom that described moulding is inserted, described connection push rod passes moving platen, and described circular arc-shaped bottom portion props up push pedal simultaneously.
Further, consider the antecedence reposition that connects push rod, the utility model is equipped with back-moving spring at the outer surface of described connection push rod.
The beneficial effects of the utility model are: the combined type design that the utility model is inserted by the moulding of inlaying in adopting and push rod ejects, and by back-moving spring realization antecedence reposition, this programme is simple in structure, and parts is few, and the manufacturing processing cost is low, efficient is high.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is cross-sectional view of the present utility model.
Among the figure: 1. solid plate, 2. moving platen, 3. backing plate, 4. push pedal, 5. moulding is inserted, and 6. connects push rod,
6-1. circular arc-shaped bottom portion, the 6-2. back-moving spring.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of injection mold with inner threaded core-pulling mechanism of the utility model as shown in Figure 1, comprise solid plate 1, moving platen 2, backing plate 3 and push pedal 4, the lateral edges of described push pedal 4 is in the base surface area that is positioned at backing plate 3 along the projection on minute mould direction, in described moving platen 2 embeddings moulding is installed and inserts 5, be installed with the connection push rod 6 with circular arc-shaped bottom portion 6-1 in insert 5 bottom of described moulding, described connection push rod 6 passes moving platen 2, and described circular arc-shaped bottom portion 6-1 props up push pedal 4 simultaneously, and the outer surface at described connection push rod 6 is equipped with back-moving spring 6-2 simultaneously.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
