Abstract
The utility model discloses a kind of mould of plastics internal core-pulling mechanism, comprise slide-and-guide block, first slide block, the location-plate be fixedly installed, be slidably arranged in the second slide block on location-plate, be arranged at the 3rd slide block between the slide block of both sides second, the both sides of the 3rd slide block are respectively arranged with the first guiding surface, the inner surface of two the second slide blocks is vertical plane, the upper surface of the first slide block has the second guiding surface, the bottom of the 3rd slide block has the 3rd guiding surface, slide-and-guide block is connected with the cylinder driving its slide anteroposterior, air cylinder driven slide-and-guide block forward slip, then the first slide block forward slip is driven, by coordinating of the second guiding surface and the 3rd guiding surface, make the 3rd slide block upward sliding, under the effect of the first guiding surface, second slide block of both sides is moved round about, thus plug and plastic product are departed from, realize synchronously loosing core, structure is simple, loose core conveniently.
Description
Technical field
The utility model relates to a kind of core-pulling mechanism, particularly a kind of mould of plastics internal core-pulling mechanism.
Background technology
Current plastic products need usually preparation two holes as rotating hole, therefore need that there is the plug that two are prepared rotating hole in the mould of plastics manufacturing plastic products, but after having prepared, plug is needed to extract out in rotating hole, current two plugs need use two core-pulling mechanisms to loose core, therefore can cause core-pulling mechanism complex structure, manufacturing cost is high, and controls inconvenient.
Utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of mould of plastics internal core-pulling mechanism, and structure is simple, looses core conveniently.
For achieving the above object, the technical solution of the utility model there is provided a kind of mould of plastics internal core-pulling mechanism, comprise slide-and-guide block, be fixedly installed on the first slide block on described slide-and-guide block, the location-plate be fixedly installed, the second slide block on described location-plate is slidably arranged in along left and right directions, the 3rd slide block described in both sides between the second slide block is arranged at along above-below direction, the both sides of described 3rd slide block are respectively arranged with the first guiding surface of inclination, the inner surface of two described second slide blocks is the vertical plane matched with described first guiding surface, the upper surface of described first slide block has the second guiding surface of downward-sloping setting, the bottom of described 3rd slide block has the 3rd guiding surface matched with described second guiding surface, described slide-and-guide block is connected with the cylinder driving its slide anteroposterior.
Further improvement: described first slide block offers the dovetail chute paralleled with described second guiding surface, the bottom of described 3rd slide block is provided with the projection matched with described dovetail chute.
Advantage of the present utility model and beneficial effect are: air cylinder driven slide-and-guide block forward slip, then the first slide block forward slip is driven, by coordinating of the second guiding surface and the 3rd guiding surface, make the 3rd slide block upward sliding, under the effect of the first guiding surface, the second slide block of both sides is moved round about, thus plug and plastic product are departed from, realize synchronously loosing core, structure is simple, looses core conveniently.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Wherein: 1, slide-and-guide block; 2, the first slide block; 3, the second slide block; 4, the 3rd slide block; 5, the first guiding surface; 6, the second guiding surface; 7, cylinder; 8, dovetail chute.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of mould of plastics internal core-pulling mechanism, comprise slide-and-guide block 1, be fixedly installed on the first slide block 2 on described slide-and-guide block 1, the location-plate be fixedly installed, the second slide block 3 on described location-plate is slidably arranged in along left and right directions, the 3rd slide block 4 described in both sides between the second slide block 3 is arranged at along above-below direction, the both sides of described 3rd slide block 4 are respectively arranged with the first guiding surface 5 of inclination, the inner surface of two described second slide blocks 3 is the vertical plane matched with described first guiding surface 5, the upper surface of described first slide block 2 has the second guiding surface 6 of downward-sloping setting, the bottom of described 3rd slide block 4 has the 3rd guiding surface matched with described second guiding surface 6, described slide-and-guide block 1 is connected with the cylinder 7 driving its slide anteroposterior.
Comparatively steady in order to make between the first slide block 2 and the 3rd slide block 4 mutually to move, described first slide block 2 offers the dovetail chute 8 paralleled with described second guiding surface 6, the bottom of described 3rd slide block 4 is provided with the projection matched with described dovetail chute 8, then the first slide block 2 is when driving the 3rd slide block 4 oscilaltion, 3rd slide block 4 moves comparatively steady, can not destroy shaping after plastic products shape.
The course of work illustrates: cylinder 7 drives slide-and-guide block 1 forward slip, then the first slide block 2 forward slip is driven, by coordinating of the second guiding surface 6 and the 3rd guiding surface, make the 3rd slide block 4 upward sliding, under the effect of the first guiding surface 5, second slide block 3 of both sides is moved round about, thus plug and plastic product are departed from.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
