Description
Technical field
The utility model relates to a kind of injection moulding die casting mouth shearing device, is specifically related to a kind of injection moulding die casting mouth automatic disconnecting device.
Background technology
Generally speaking, injection moulding die casting mouth refers to one section of passage from runner to mold cavity, is the minimum and the shortest part in running gate system middle section.The position of cast gate, quantity, the outward appearance of shape and size to plastic products quality, product all have a direct impact, and therefore need the design paying attention to cast gate in the design process.General sprue and runners connects, and the material for molding injection injects cavity and forms moulded product.Product and cast gate to be separated employing manually shearing, add the amount of labour of workman, production efficiency is low, and sheared edge is inconsistent, needs for further processing.
Utility model content
The utility model aims to provide a kind of injection moulding die casting mouth automatic disconnecting device, to cut off and is separated, enhance productivity, reduce the quantity of workman, make incision of product more attractive in appearance to realize product with cast gate in injection mold.
In order to solve the problem, the injection moulding die casting mouth automatic disconnecting device that the utility model provides have employed following technical scheme:
A kind of injection moulding die casting mouth automatic disconnecting device, comprise runner, cast gate, first thimble, second thimble, described runner is connected with cast gate, cast gate is connected with product, it is characterized in that: the second thimble is installed below described runner, the second described thimble is time delay thimble, the structure that described cast gate is connected with product is back-off structure, first thimble is installed below described product, the first described thimble lower end is connected with the first ejector retainner plate, the second described thimble bottom is through the first ejector retainner plate, and be connected with the second ejector retainner plate, be the second ejector retainner plate below the first described ejector retainner plate, it is top board below second ejector retainner plate.
Preferably, the second described thimble and the connection of runner are that buckle-type connects.
The beneficial effects of the utility model are: provide a kind of injection moulding die casting mouth automatic disconnecting device, by the time delay of back-off structure and thimble, achieve product to be separated with cast gate automatic cut-out in injection mold, improve production efficiency, decrease artificial secondary operations simultaneously, decrease the quantity of workman, and make the unification more attractive in appearance of the otch of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged diagram of A place structure in Fig. 1.
Wherein: 0. product; 1. runner; 2. cast gate; 21. back-off structure; 3. the first thimble; 31. first ejector retainner plates; 4. the second thimble; 41. second ejector retainner plates; 5. top board.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As depicted in figs. 1 and 2, the utility model provides a kind of injection moulding die casting mouth automatic disconnecting device, comprise runner 1, cast gate 2, first thimble 3, first ejector retainner plate 31, second thimble 4, second ejector retainner plate 41, described runner 1 is connected with cast gate 2, cast gate 2 is connected with product 0, it is characterized in that: two second thimbles 4 are installed below described runner 1, the second described thimble 4 is time delay thimble, the structure that cast gate 2 is connected with product 0 is back-off structure 21, first thimble 3 is installed below described product 0, the first described thimble 3 lower end is connected with the first ejector retainner plate 31, the second described thimble 4 bottom is through the first ejector retainner plate 31, and be connected with the second ejector retainner plate 41, be the second ejector retainner plate 41 below the first described ejector retainner plate 31, be top board 5 below second ejector retainner plate 41.
In the utility model preferred embodiment, the second described thimble 4 is that buckle-type connects with the connection of runner 1, makes the second thimble 4 be not easy to be separated with runner 1, when preventing cast gate 2 and product 0 from cutting off, runner 1 is separated with the second thimble 4, affects the separation cut of product 0 and cast gate 2.
Operation principle of the present utility model is: first top board 5 moves upward, and product 0 and runner 1 upwards eject simultaneously, product 0 and runner 1 break away from moulds; After product 0 and runner 1 break away from moulds, first thimble 3, first ejector retainner plate 31, second thimble 4, second ejector retainner plate 41 moves upward, now because the second thimble 4 is time delay thimble, it does not promote runner 1 and moves upward, but now product 0 moves upward, because product 0 to be connected for back-off structure with cast gate 2, cast gate 2 and runner 1 are common to be entirely connected, therefore product and the easier cut-out of cast gate, and to product not damaged.Such the utility model, by the automatic disconnecting device in mould, achieves injection moulding die casting mouth 2 and the automatic cut-out of product 0, improves production efficiency, decrease the quantity of workman simultaneously, and make the unification more attractive in appearance of the otch of product 0.
The beneficial effects of the utility model are: provide a kind of injection moulding die casting mouth automatic disconnecting device, achieve product to be separated with cast gate automatic cut-out in injection mold, improve production efficiency, decrease artificial secondary operations simultaneously, decrease the quantity of workman, and make the unification more attractive in appearance of the otch of product.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model change or modify, and all should be encompassed within protection domain of the present utility model.
