Description
Technical Field
The utility model belongs to the technical field of the mould technique and specifically relates to a flip-chip mould demoulding structure.
Background
The product back advances gluey mould and is the flip-chip die structure, and to the demoulding mechanism of flip-chip die, all ejecting through ejector plate cooperation ejection mechanism with the product, makes the product automatic drop. However, this kind of mold is complicated in structure, and the thickness of the mold is increased, and the length of the hot runner and the hot nozzle is increased to be non-standard, which results in the increase of the manufacturing cost by times. And the complex structure can increase the installation difficulty and the maintenance difficulty, and can also influence the stability of operation.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a flip-chip mould demoulding structure.
The utility model discloses specifically adopt following technical scheme to realize:
the utility model provides a flip-chip mould demoulding structure, includes front template, back template, movable mould, cover half and thimble board, the front template is fixed on the movable mould, and the cavity is used for the shaping product between front template and the back template, the thimble board is located the back template with between the cover half, seted up on the front template and avoided the groove, nylon buckle places in dodge in the groove, the one end that nylon was buckled is fixed on the release link, the other end and connecting rod joint, the connecting rod is fixed on the movable mould, the other end of release link is fixed on the thimble board, be equipped with an at least thimble on the thimble board.
Preferably, a limiting insert is further arranged in the avoidance groove of the front template.
Preferably, the avoiding grooves are formed in the two ends of the front template, and nylon buttons are placed in the avoiding grooves.
Preferably, the thimble is located inside the reset rod.
The utility model provides a flip-chip mould demoulding structure, its beneficial effect lies in: when the mold is opened, the front mold plate is firstly separated for a certain distance to separate the front mold plate from the product, and then the connecting rod, the nylon buckle and the reset rod are driven to pull the ejector pin on the ejector pin plate to be ejected upwards, so that the product is demoulded from the rear mold plate. Through the improvement in the aspect of the structure, the structure of the die can be simplified, and the die space can be fully utilized and saved.
Drawings
Fig. 1 is a schematic view of the demolding structure of the flip-chip mold of the present invention.
Detailed Description
To further illustrate the embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The present invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1, the flip-chip mold demoulding structure provided by the embodiment comprises a front template 1, a rear template 2, a movable mold 3, a fixed mold 4 and an ejector plate 5, wherein the front template 1 is fixed on the movable mold 3, a cavity between the front template 1 and the rear template 2 is used for forming a product 11, and the ejector plate 5 is arranged between the rear template 2 and the fixed mold 4. Wherein, the both ends of front template 1 have all been seted up and have been dodged the groove, and every dodges and has placed nylon fastener 6 and spacing mold insert 7 in the groove, and the buckling part and the connecting rod 8 joint of nylon fastener 6 upper end, connecting rod 8 are fixed on movable mould 3, and 6 bottom mounting of nylon fastener are on release link 9, and the other end of release link 9 is fixed on thimble board 5 again, and the inboard of release link 9 sets up thimble 10.
In the flip-chip demoulding structure of the embodiment, in a mould closing state, the nylon buckle 6 and the connecting rod 8 are in a clamping state, and the nylon buckle 6 is in a loose state and is not tightened; after the product 11 is formed, the mold is opened, the movable mold 3 drives the front template 1 to be separated for a certain distance firstly, so that the front template 1 is separated from the product 11, the front template stops rising under the action of the limiting insert 7 after rising for a certain distance, and the nylon buckle 6 is in a tightening state at the moment; the movable mold 3 further ascends, the connecting rod 8 drives the nylon buckle 6, the nylon buckle 6 drives the reset rod 9, the reset rod 9 drives the ejector plate 5, and the ejector plate drives the ejector pins to eject upwards, so that the product 11 is demoulded from the rear mold plate 2; after the mold is lifted for a certain distance, the reset rod 9 props against the front template 1, so that the nylon fastener 6 cannot continuously lift, and the movable mold 3 drives the connecting rod 8 to lift, so that the nylon fastener 6 and the connecting rod 8 are disengaged, and a product demolding action is completed. When the die is reused next time, before die assembly, the movable die 3 drives the connecting rod 8 to descend for a certain distance, the connecting rod 8 and the nylon fastener 6 are manually clamped, and then the die assembly can be carried out, and next action circulation is carried out.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
