Description
Technical field
The utility model relates to a kind of core-pulling mechanism, particularly a kind of core-pulling mechanism retreated that prevents from loosing core.
Background technology
Current plastic products need usually prepare hole, therefore the plug with two preparation holes is needed in the mould of plastics manufacturing plastic products, but after having prepared, plug is needed to extract out in hole, current use core-pulling mechanism is loosed core, existing core-pulling mechanism is generally all crossed hydraulic oil cylinder driving skid and is reached the object of loosing core, but plastic products processing process in slide block without locking, namely under injection moulding high pressure, slide block meeting reverse slide, then plug departs from plastic products, easily makes plastic products produce burr.
Utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of core-pulling mechanism retreated that prevents from loosing core, and makes plastic products can obtain effective location adding man-hour slide block, thus is fixed by plug, ensure plastic products quality.
For achieving the above object, the technical solution of the utility model there is provided a kind of core-pulling mechanism retreated that prevents from loosing core, comprise L-shaped benchmark fixed block, on the level board of described benchmark fixed block, horizontal slip is provided with the first slide block, described first slide block is by hydraulic oil cylinder driving of loosing core, described first slide block upper surface offers downward-sloping chute, slide in described chute and be provided with the second slide block, described second slide block is vertically fixed with core-pulling member, retaining slide block is provided with between the vertical panel of described benchmark fixed block and described first slide block, described retaining slide block is vertically slided by retaining hydraulic oil cylinder driving, the bottom of described retaining slide block has inclined guide surface, described first slide block has the inclined-plane matched with described inclined guide surface.
Further improvement: the vertical panel of described benchmark fixed block offers perforation, described in the loose core piston rod of oil cylinder be fixedly connected through described perforation and described first slide block.
Advantage of the present utility model and beneficial effect are: plastic products are adding man-hour, by retaining slide block by the first slider locks, prevent its reverse slide and drive core-pulling member to move when Product processing, avoid product to produce burr, improve the quality of products.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Wherein: 1, benchmark fixed block; 2, the first slide block; 3, the second slide block; 4, to loose core oil cylinder; 5, chute; 6, core-pulling member; 7, retaining slide block; 8, retaining oil cylinder.
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 core-pulling mechanism retreated that prevents from loosing core, comprise L-shaped benchmark fixed block 1, on the level board of described benchmark fixed block 1, horizontal slip is provided with the first slide block 2, described first slide block 2 is driven by oil cylinder 4 of loosing core, described first slide block 2 upper surface offers downward-sloping chute 5, slide in described chute 5 and be provided with the second slide block 3, described second slide block 3 is vertically fixed with core-pulling member 6, retaining slide block 7 is provided with between the vertical panel of described benchmark fixed block 1 and described first slide block 2, described retaining slide block 7 is driven by retaining oil cylinder 8 and vertically slides, the bottom of described retaining slide block 7 has inclined guide surface, described first slide block 2 has the inclined-plane matched with described inclined guide surface.
In order to ensure stability of loosing core, the vertical panel of described benchmark fixed block 1 offers perforation, described in the loose core piston rod of oil cylinder 4 be fixedly connected through described perforation and described first slide block 2.
Operation principle illustrates: when loosing core, retaining oil cylinder 8 drives retaining slide block 7 upward sliding, it is made to depart between benchmark fixed block 1 and the first slide block 2, first slide block 2 is unlocked, oil cylinder 4 of loosing core drives the first slip to move backward, then the second slide block 3 slides along the tip chute 5 of the first slide block 2, thus drives core-pulling member 6 fixed thereon to depart from working of plastics;
During plastic product injection moulding, retaining oil cylinder 8 drives retaining slide block 7 slide downward, is locked by the first slide block 2, prevent it from sliding backward because pressure is excessive in the process of high-pressure injection moulding, thus improve the accuracy of plug position, ensure that product can not produce burr when injection moulding, improve the quality of products.
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.
