Abstract
The utility model discloses an injection mold with a floating core mechanism, comprising an ejector rod fixing plate and an ejector rod backing plate, wherein an angle ejector rod and an ejector rod are connected on the ejector rod fixing plate, the angle ejector rod is matched with a reverse buckle of a product and the ejector rod is pushed against the lower end surface of the product; a step through hole is formed in the ejector rod backing plate and is internally matched with a limit block, a limit rod is fixedly arranged on the limit block, a connecting rod is fixedly connected on the limit rod, a floating core is articulated on the connecting rod and is supported on the bottom surface of the product, a spring-ejecting device is pressed below the limit block and comprises an elastic sleeve contacted with the limit block, and a spring is arranged in the elastic sleeve. The floating core mechanism is realized and automatic production of the products can be achieved under the condition that no other characteristics and traces are increased on the products, and the existing local deep ribs on the products are utilized and the structure is simple.
Description
Technical field
The utility model relates to the injection mold field, specifically belongs to the injection mold that has floating-type core mechanism.
Background technology
Have ramp-roof structure for some injection molds, mold cores is lower, and the oblique bigger mould of top stroke; Product is in the process of ejecting; After product broke away from core, product can be bonded on the oblique top, causes oblique top from the back-off of product, not spin off fully; Take out thereby influence product, can not realize automated production.
The utility model content
The purpose of the utility model provides a kind of injection mold that has floating-type core mechanism; Under the situation that can not increase the product further feature; Make floating-type core mechanism, utilize the dark muscle in existing part on the product, simple in structure; On product, do not increase unnecessary characteristic and vestige, realize the automated production of product.
The technical scheme of the utility model is following:
The injection mold that has floating-type core mechanism includes push rod fixed head, push rod backing plate, is connected with angle ejector rod, push rod on the top board fixed head; The back-off of angle ejector rod and product is complementary, and the push rod overhead has step through-hole in the push rod backing plate on the lower surface of product; Be combined with limited block in the step through-hole, be fixed with gag lever post on the limited block, be fixedly connected with connecting rod on the gag lever post; Be hinged with floating-type core on the connecting rod, the floating-type core holder places the bottom surface of product, and the below of limited block is pressed and is equipped with the bullet top; The bullet top includes and the contacted resilient sleeve of limited block, is provided with spring in the resilient sleeve.
The lower end of described limited block is fixedly connected with bolt, and the upper end of bolt and connecting rod fix and screw togather.
After the injection mold of the utility model was opened, the top rod of injection machine promoted push rod backing plate and push rod fixed head, and push rod backing plate and push rod fixed head drive push rod, angle ejector rod; Angle ejector rod moves together; Thereby promote the product motion, utilize product self to shrink the package power of generation and the thrust on bullet top, bullet plays auxiliary impetus when withstanding on floating-type core assembly setting in motion; The floating-type core assembly is made up of floating-type core, resilient key, connecting rod, gag lever post, limited block and bolt; Be synchronized with the movement with product, when gag lever post arrived moving platen, the oblique top of both sides spun off from the back-off of product fully.The top rod of injection machine continues to promote push rod backing plate and push rod fixed head, floating-type core assembly stop motion at this moment, and push rod, tiltedly pushing tow movable property article continue to move, and when product disengaging floating-type core, eject and stop, and take product away.The push rod backing plate drives limited block when retreating, the floating-type core assembly is resetted.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, have the injection mold of floating-type core mechanism, include push rod fixed head 1, push rod backing plate 2; Be connected with angle ejector rod 3, push rod 4 on the top board fixed head 1, angle ejector rod 3 is complementary with the back-off of product 5, and push rod 4 overheads are on the lower surface of product 5; Have step through-hole 6 in the push rod backing plate 2, be combined with limited block 7 in the step through-hole 6, be fixed with gag lever post 8 on the limited block 7; Be fixedly connected with connecting rod 9 on the gag lever post 8, be hinged with floating-type core 10 on the connecting rod 9, floating-type core 10 holders place the bottom surface of product 5; The below of limited block is pressed and is equipped with the bullet top, and the bullet top includes and the contacted resilient sleeve 11 of limited block, is provided with spring 12 in the resilient sleeve 11; The lower end of limited block 7 is fixedly connected with bolt, and the upper end of bolt and connecting rod fix and screw togather.
Claims (2)
1. the injection mold that has floating-type core mechanism includes push rod fixed head, push rod backing plate, is connected with angle ejector rod, push rod on the top board fixed head; The back-off of angle ejector rod and product is complementary, and the push rod overhead is characterized in that on the lower surface of product: have step through-hole in the push rod backing plate; Be combined with limited block in the step through-hole, be fixed with gag lever post on the limited block, be fixedly connected with connecting rod on the gag lever post; Be hinged with floating-type core on the connecting rod, the floating-type core holder places the bottom surface of product, and the below of limited block is pressed and is equipped with the bullet top; The bullet top includes and the contacted resilient sleeve of limited block, is provided with spring in the resilient sleeve.
2. the injection mold that has floating-type core mechanism according to claim 1 is characterized in that: the lower end of described limited block is fixedly connected with bolt, and the upper end of bolt and connecting rod fix and screw togather.
