Abstract
The utility model relates to a sliding block core pulling mechanism of an injection mold. The sliding block core pulling mechanism of the injection mold comprises a sliding block insert moving piece A, a sliding block insert moving piece B, a sliding block insert pushing block, a sliding block insert positioning piece, a sliding block seat, a shovel base and a pressing strip, wherein the sliding block insert moving piece A and the sliding block insert moving piece B are arranged on the sliding block insert positioning piece; the sliding block insert pushing block is matched, combined and fixedly connected with the sliding block insert positioning piece; the rear end of the sliding block insert pushing block is connected with one end of a spring; the other end of the spring is fixedly clamped inside the sliding seat; the sliding seat is pressed and mounted on the shovel base through the pressing strip. A sliding block insert pushing piece is pushed to move forward under the action of spring force and pushes the sliding block insert moving pieces to move downward; when the sliding block insert moving pieces are disengaged from inverted hooks of a product, a sliding block performs synchronous core pulling movement, so that the core pulling motion of the sliding block is realized.
Description
Technical field
The utility model relates to a kind of injection mould slide block core-pulling mechanism.
Background technology
In recent years, modernization mould industry is fast-developing, plastic mould is widely used in industrial production, structural requirement to plastic mould is also more and more higher, the particularly fast development of automobile industry, the structure of automobile plastic cement part product also becomes increasingly complex various, and plastic mould must meet the structural requirement of auto parts, and some traditional sliding block core-pulling mechanisms cannot reach the production requirement of auto parts.Injection mould slide block core-pulling mechanism, is by take-up housing and slide block, to enter the active force of spring between sub-impeller, promotes slide block and enters subactivity part and slide block and enter the guide effect of sub-keeper dovetail groove and move downward, and realizes the automatic trip of loosing core from product.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of injection mould slide block core-pulling mechanism is provided, and while solving employing traditional moulds structure production product, part is laterally loosed core and cannot be realized the problem of the demoulding.
An injection mould slide block core-pulling mechanism, comprises that slide block enters subactivity part A4, slide block and enters that subactivity part B5, slide block enter sub-pushing block 3, slide block enters sub-keeper 2, take-up housing 9, shovel base 7 and press strip 10;
Described slide block enters subactivity part A4 and slide block and enters subactivity part B5 and be arranged on slide block and enter on sub-keeper 2, slide block enters sub-pushing block 3 and slide block and enters sub-keeper 2 and mate combination and be fixedly connected with, the rear end that slide block enters sub-pushing block 3 is connected with one end of spring 8, and the other end fixed card of spring 8 is located at the inside of take-up housing 9; Take-up housing 9 is compressed and is arranged on shovel base 7 by press strip 10.
The utility model is simple in structure, easy to process.Mainly contain following beneficial effect:
1. use spring-force driven dual to promote slide block and enter sub-impeller and travel forward, slide block enters sub-impeller to be promoted slide block and enters subactivity part and move downward, and when slide block enters subactivity part, departs from after product overhead kick, and slide block is done the motion of synchronously loosing core, and realizes slipper block loose core and moves.
2. mould is simple and reasonable, and the having stable behavior of mechanism guarantees the smooth-going volume production of mould.
3. adopt after the utility model, mould structure is simplified, and Mould Machining also becomes easily, does not produce overhead kick and the problem such as pull in injection moulding production process.
Accompanying drawing explanation
Fig. 1 is plastic cement products structural representation.
Fig. 2 is injection mould slide block core-pulling mechanism schematic diagram.
Fig. 3 is the separated schematic diagram of injection mould slide block core-pulling mechanism part.
1-part in figure; 2-slide block enters sub-keeper; 3-slide block enters sub-pushing block; 4-slide block enters subactivity part A; 5-slide block enters subactivity part B; Another part of 6-; 7-shovels base; 8-spring; 9-take-up housing; 10-press strip.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
As shown in Figure 1, be plastic cement products structural representation.As shown in Figures 2 and 3, be a kind of injection mould slide block core-pulling mechanism, comprise that slide block enters subactivity part A4, slide block and enters that subactivity part B5, slide block enter sub-pushing block 3, slide block enters sub-keeper 2, take-up housing 9, shovel base 7 and press strip 10;
Described slide block enters subactivity part A4 and slide block and enters subactivity part B5 and be arranged on slide block and enter on sub-keeper 2, slide block enters sub-pushing block 3 and slide block and enters sub-keeper 2 and mate combination and be fixedly connected with, the rear end that slide block enters sub-pushing block 3 is connected with spring 8, and the other end fixed card of spring 8 is located at the inside of take-up housing 9; Take-up housing 9 is compressed and is arranged on shovel base 7 by press strip 10.
After plastic cement products moulding, in die sinking process, slide block starts to realize the action of loosing core, slide block enters sub-keeper 2 and is synchronized with the movement with fixing realization of take-up housing, slide block enters subactivity part A4, slide block enters subactivity part B 5 sub-pushing block 3 effects because the promotion slide block of the power effect of product back-off and spring 8 power enters, the dovetail groove guide direction that slide block enters sub-keeper 2 drags slide block and enters subactivity part A4, slide block enters subactivity part B 5 and moves downward, when slide block enters subactivity part A4, slide block enters subactivity part B 5 and departs from after product back-off stroke, slide block enters sub-keeper 2 and enters subactivity part A4 with slide block, slide block enters subactivity part B 5 and slide block enters sub-impeller 3, along take-up housing 7 direction of loosing core, be synchronized with the movement, described sliding block core-pulling mechanism completes the plastic cement products action of loosing core.The utility model has solved cannot laterally the loose core problem of the demoulding of traditional plastic cement part 1 and another part 6 slide blocks.
