The plastic product structure is the outward appearance face like the front mould, and the side also has outward appearance requirement and assembly requirement, for not influencing the outward appearance, simultaneously can automatic production, so consider the mould design flip-chip advance gluey injection moulding.

The existing flip-chip ejection structure basically adopts an oil cylinder ejection mode, an oil cylinder needs to occupy a large amount of mold space, the mold structure is complex, oil cylinder oil circuit connection is poor, oil leakage can pollute products in the injection molding production process, and the products are scrapped to increase the production cost. The purchasing cost and the processing cost of the die can be greatly increased by using the oil cylinder for ejection, the design difficulty and the processing period can be increased, and the order receiving range is reduced.

In a conventional flip-chip ejector mechanism, an ejector pin panel and an ejector pin base plate are combined into a whole by screws, which is hereinafter referred to as an ejector pin plate; the ejector plate is connected with the oil cylinder through a connecting block. When the injection molding of the mold is finished, the front mold and the rear mold of the mold are opened in advance, then the oil is fed into the oil cylinder, the oil cylinder acts to drive the ejector plate to move for a certain distance to be attached to the bottom of the rear mold blank, the travel switch is switched on, the oil cylinder cuts off the oil, the ejection action is finished, and a product is taken out; and the oil is fed into the oil cylinder again, the ejector pin plate is reset, the stroke switches are communicated, the oil cylinder is cut off, the ejector pin plate returns to the initial position, and the front mold and the rear mold are closed, so that an injection molding cycle is completed in cycles. This kind of structure relies on the hydro-cylinder action to control the thimble board motion, and design hydro-cylinder mould structure is more complicated, can increase the mould, can correspondingly increase to the board of moulding plastics and transfer quick-witted personnel quality requirement, increases mould cost and processing cycle, and the centering small-size mould has great limitation. Is not beneficial to reducing the production cost, thereby reducing the order receiving range of small and medium-sized manufacturers.

Accordingly, the prior art is deficient and needs improvement.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, the present invention provides a flip-chip mold ejection device, including: an a plate 1, a B plate 2, and an ejector 3. The ejection device 3 includes: a pull plate holder 31 and a pull plate 32. One end of the pulling plate 32 is embedded into the pulling plate fixing piece 31 and moves up and down along the pulling plate fixing piece 31, the pulling plate fixing piece 31 is connected with the B plate 2, the A plate 1 is movably covered with the B plate 2, the A plate 1 is connected with the ejector plate 4, and the other end of the pulling plate 32 is connected with the ejector plate 4. Referring to fig. 3 and 4, after the injection molding operation is completed and the fixed mold is opened, the pull plate moves to the limit position relative to the pull plate fixing member 31, the ejector plate 4 is driven to move to the bottom limit position and then stops moving, and at this time, the mold completes all the ejection actions, so that the product can be conveniently taken out. And then the injection molding machine returns, the B plate 2 touches the return needle to drive the ejector plate 4 to return, the whole injection molding period is completed, and the cycle is repeated, so that the continuous production is realized. The utility model provides an ejecting device 3 direct mount does not occupy the mould exterior space on ejector plate 4 and B board 2, convenient compactness to because only pulling and spacing effect between arm-tie 32 and the arm-tie mounting 31, the required precision to ejecting device 3 is lower, and the accessory is few, and the reliability is high, the design and the manufacturing of being convenient for.
