Description
Technical field
The utility model relates to mould structure technical field, particularly a kind of mould slide block retreating prevention mechanism.
Background technology
If generally the front mold slide of injection mold directly drives with oil cylinder shovel base; and the shaping glue plane of slide block amasss excessive and huge injection pressure that is that produce is greater than the oil pressure that oil cylinder is applied to slide block; front mold slide will be forced to support injection pressure and produce the situation of retrogressing; therefore bad substandard products can be brought; directly affect product appearance and wall thickness, cause product defective.
Existing inventor overcomes above defect, and develop a kind of mould slide block retreating prevention mechanism, it can prevent front mold slide from cannot support injection pressure and produce the situation of retrogressing.
Utility model content
The purpose of this utility model solves above defect, provides a kind of mould slide block retreating prevention mechanism, and its structure is simple, can effectively prevent front mold slide injection pressure and produce retrogressing.
The purpose of this utility model is achieved in the following ways:
A kind of mould slide block retreating prevention mechanism, comprise the shovel base be arranged in A plate, the front end of described shovel base is provided with core-pulling slide block, this core-pulling slide block is respectively four faces, stud with the first wear-resistant block all on each face, the bottom side of described shovel base is provided with outwardly T-shaped piece, the inside of T-shaped piece caves inward formation one T groove, and mutually match with core-pulling slide block and be connected, described shovel base rear end is connected with for driving the reciprocating driving oil cylinder of shovel base, also comprise pressure when being provided with for preventing injection moulding and produce the anti-receding device retreated, described anti-receding device is by time delay slide block, block and elastic component are formed, this elastic component is provided with two altogether, corresponding elastic component is provided with two and screws for the plug controlling block action, one end that this plug screws penetrates in block, and be fixed in A plate by thread, fill in the surface that the other end screwed extends to elastic component, this time delay slide block is connected with driving the output shaft of oil cylinder by contiguous block, the both sides of time delay slide block are fixed in shovel base by briquetting, the effect being subject to time delay slide block when block moves downward, block moves up and down by elastic component.Time delay slide block first to move a segment distance in shovel base, and substantially the experience effect of block of shovel is not first transported, and after time delay slide block first paragraph move, can encounter and shovel base and drive subsequently and move together.
In above-mentioned explanation, more preferred scheme, the little inclined-plane of the downward-sloping formation in front end one of described shovel base, and correspondence is provided with the second wear-resistant block on this little inclined-plane.
In above-mentioned explanation, more preferred scheme, described little inclined-plane is also provided with the fixed block for fixing the second wear-resistant block.
In above-mentioned explanation, more preferred scheme, described elastic component is spring.
The beneficial effect that the utility model produces is: compared with prior art; the utility model increases in the inside of shovel base time delay slide block; thereunder be provided with the block with coil tension spring and stay one section of straight body face to block shovel base simultaneously; can effectively prevent front mold slide from cannot support injection pressure and produce the situation of retrogressing; structure is simple, and maintenance cost is low.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
The present embodiment, with reference to Fig. 1 ~ Fig. 4, it specifically implements to comprise the shovel base 1 be arranged in A plate, the front end of described shovel base 1 is provided with core-pulling slide block 2, this core-pulling slide block 2 is respectively four faces, stud with the first wear-resistant block 3 all on each face, loss friction when this design facilitates pincers worker to join mould and reduces motion, the bottom side of described shovel base 1 is provided with outwardly T-shaped piece 4, the inside of T-shaped piece 4 caves inward formation one T groove, and mutually match with core-pulling slide block 2 and be connected, described shovel base 1 rear end is connected with for driving the reciprocating driving oil cylinder 5 of shovel base 1.
Be unlike the prior art, also comprise pressure when being provided with for preventing injection moulding and produce the anti-receding device retreated, described anti-receding device is by time delay slide block 6, block 7 and elastic component 8 are formed, this elastic component 8 is provided with two altogether, corresponding elastic component 8 is provided with two and screws 9 for the plug controlling block 7 action, reaching block 7 can automatically reset effect, this plug screw 9 one end penetrate in block 7, and be fixed in A plate by thread, plug screw 9 the other end extend to the surface of elastic component 8, the elastic component 8 of the present embodiment is spring, this time delay slide block 6 is connected with driving the output shaft of oil cylinder 5 by contiguous block 12, the both sides of time delay slide block 6 are fixed in shovel base 1 by briquetting, the effect being subject to time delay slide block 6 when block 7 moves downward, block 7 moves up and down by elastic component 8.
In the present embodiment, the little inclined-plane of the downward-sloping formation in front end one of described shovel base 1, and correspondence is provided with the second wear-resistant block 10 on this little inclined-plane.Described little inclined-plane is also provided with the fixed block 11 for fixing the second wear-resistant block 10.
Its whole process can be divided into two sections of motions, when first paragraph motion is loosed core, oil cylinder 5 is driven to drive time delay slide block 6 first to move a segment distance by fixing contiguous block 12, in the process, the effect that block 7 is subject to time delay slide block 6 can move downward, time delay slide block 6 just encounters shovel base 1, and the straight body position blocking shovel base 1 also disappears thereupon; Second segment motion drives oil cylinder 5 when loosing core again, and time delay slide block 6 can then drive shovel base 1 move backward together, and in this process, core-pulling slide block 2 is owing to being that gradient T groove couples together, so core-pulling slide block 2 can exit the back-off of product with shovel base 1.Compared with prior art; the utility model increases in the inside of shovel base 1 time delay slide block 6; thereunder be provided with the block 7 with coil tension spring simultaneously and stay one section of straight body face to block shovel base 1; can effectively prevent front mold slide from cannot support injection pressure and produce the situation of retrogressing; structure is simple, and maintenance cost is low.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as protection domain of the present utility model.
