Abstract
The utility model discloses a sliding block core pulling mechanism capable of realizing auxiliary pressing a product. The sliding block core pulling mechanism mainly consists of a sliding block, a wedging block, an ejector pin mechanism and a baffle. The ejector pin mechanism comprises an ejector pin base board, an ejector pin fixing board, an ejector pin and a spring, wherein the ejector pin base board and the ejector pin fixing board are fixed together and are slidingly connected in a sliding groove of the sliding block, the bottom flange of the ejector pin is clamped between the ejector pin base board and the ejector pin fixing board, the spring is arranged between the ejector pin fixing board and the bottom surface of the sliding groove of the sliding block, the wedging surface of the wedging block pushes against the external end surface of the ejector pin base board, and the baffle is arranged at the notch of the sliding groove of the sliding block. As the sliding block core pulling mechanism is provided with the ejector pin mechanism, the ejector pin mechanism can press the product in an auxiliary way when in the sliding block core pulling, the product can be kept still temporarily and delays by the straight wall section of the wedging block within the small range, and then the spring assists the product to go back to the original position; and the ejector pin mechanism in the sliding block is combined with the sliding block so that the product can be demoulded smoothly. The sliding block core pulling mechanism has the advantages that the structure is compact, and the space is saved.
Description
Technical field
The utility model relates to a kind of injection mold, but particularly relates to a kind of slide block core-pulling mechanism of auxiliary top die pressing product.
Background technology
Present product structure design becomes increasingly complex, and often will carry out slide block and loose core, could the demoulding.But some is directly loosed core and may draw bad product, and this just requires to assist when slide block is loosed core and withstands product, makes product temporarily motionless, is not drawn bad when guaranteeing product stripping.
The utility model content
But the purpose of this utility model is to provide the slide block core-pulling mechanism of the auxiliary top die pressing product of a kind of effective assurance product quality, compact conformation.
For achieving the above object, technical solution of the present utility model is:
But the utility model is a kind of slide block core-pulling mechanism of auxiliary top die pressing product, and it mainly is made up of slide block, wedge block, ejector pin mechanism, block; Described ejector pin mechanism comprises Ejector Retainer Plate, thimble fixed head, thimble, spring; Described Ejector Retainer Plate and thimble fixed head are fixed together and slip in the chute of slide block; The base flange of described thimble is clamped between Ejector Retainer Plate and the thimble fixed head, and the top of thimble passes slide block and stretches into die cavity, and spring is arranged on the outer face of thimble fixed head and between the outer face and slide block chute bottom surface of thimble fixed head; The wedging face of described wedge block leans the outer face at Ejector Retainer Plate; Described block is arranged on the notch of slide block chute, can block the ejector pin mechanism of ejection.
The wedging mask of described wedge block has wall section always, and the outer face of Ejector Retainer Plate has wall section always; When wedge block leaned Ejector Retainer Plate, the straight wall section of wedge block wedging face leaned on the straight wall section of the outer face of Ejector Retainer Plate.
After adopting such scheme, because the utility model is provided with ejector pin mechanism, this ejector pin mechanism can be assisted when slide block is loosed core and be withstood product, make product temporarily motionless,, utilize the auxiliary reset of spring again postponing by the straight wall section of wedge block among a small circle, the sequence of movement of the ejector pin mechanism in slide block and the slide block is separated, make the smooth demoulding of product, prevent that effectively product from being drawn bad problem, guaranteed the quality of product., satisfied the product structure requirement, do not increase core-pulling mechanism again.Have compact conformation, save the space, dwindle the advantage of mould bases size, very big promotion prospect is arranged.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is an axonometric drawing of the present utility model;
Fig. 2 is matched moulds state diagram of the present utility model;
Fig. 3 is die opening state figure of the present utility model;
Fig. 4 is the axonometric drawing of the utility model ejector pin mechanism.
The specific embodiment
As shown in Figure 1 and Figure 2, but the utility model is a kind of slide block core-pulling mechanism of auxiliary top die pressing product, and it mainly is made up of slide block 1, wedge block 2, ejector pin mechanism 3, block 4.
With reference to shown in Figure 4, described ejector pin mechanism 3 comprises Ejector Retainer Plate 31, thimble fixed head 32, thimble 33, spring 34.The inner face of the inner face of described Ejector Retainer Plate 31 and thimble fixed head 32 is fitted and is fixed together, and Ejector Retainer Plate 31 that is fixed together and thimble fixed head 32 slip in the chute 11 of slide block 1.The base flange 331 of described thimble 33 is clamped between Ejector Retainer Plate 31 and the thimble fixed head 32, and the top of thimble 33 passes slide block 1 and stretches into die cavity and withstand on the product 10.Spring 34 is arranged on the outer face of thimble fixed head 32 and between the outer face and slide block 1 chute 11 bottom surfaces of thimble fixed head 32.
As shown in Figure 2, the wedging face 21 of described wedge block 2 leans the outer face at Ejector Retainer Plate 31.
The wedging face 21 of described wedge block 2 has wall section 211 always, and its cross section is tiltedly, straight, oblique shape.The outer face of Ejector Retainer Plate 31 also has wall section 311 always.When wedge block 2 leaned Ejector Retainer Plate 31, the straight wall section 211 of wedge block 2 wedging faces 21 leaned on the straight wall section 311 of the outer face of Ejector Retainer Plate 31.In actual design, when the length of the straight wall section 211 of wedge block 2 wedging faces 21 is got 8.5mm, slide block 1 4mm of can having loosed core earlier.
Described block 4 is arranged on the notch of slide block 1 chute 11, can keep off on ejector pin mechanism 3 Ejector Retainer Plates 31 that eject.
Operation principle of the present utility model:
With reference to shown in Figure 3, during die sinking, be located at the ejector pin mechanism 3 in the slide block 1 because by 2 grades of the wedge blocks of 33 groups on thimble, thimble 33 can head on product 10, slide block 1 action earlier.When opening stroke reaches 8.5mm, slide block 1 4mm of having loosed core earlier, 10 pairs of slide blocks 1 of product have not been held power tightly substantially like this, and the wedge block 2 straight wall sections 211 of 33 groups on thimble are just covered, ejector pin mechanism 3 is by spring 34(as shown in Figure 4 when continuing die sinking) eject and reset and slide block 1 is finished together and loosed core.The inclined-plane of wedge block 2 front ends can be compressed into ejector pin mechanism 3 earlier during matched moulds, avoids straight wall section to shovel Ejector Retainer Plate 31.
Emphasis of the present utility model just is: an ejector pin mechanism is set.
The above, it only is the utility model preferred embodiment, the fit form of wedge block and Ejector Retainer Plate can have multiple, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
