Detailed Description

It is to be noted that the experimental methods described in the following embodiments are all conventional methods unless otherwise specified, and the reagents and materials, if not otherwise specified, are commercially available; in the description of the present application, the terms "lateral," "longitudinal," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention.

Furthermore, the terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present application, it is further noted that, unless expressly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 2-6, a mold structure for automatically breaking a material head on a slide block may include a movable mold core 1, a fixed mold core 2, a slide block 3, a product insert 4, and a blocking insert 5. The slide block 3 is arranged between the movable mould core 1 and the fixed mould core 2 and is provided with a submarine gate 31. A plurality of product cavities 10 are formed among the movable mould core 1, the sliding block 3 and the fixed mould core 4. The product insert 4 is mounted in the product cavity 10. A runner (not shown) is formed between the core insert 2 and the slide block 3, and the blocking insert 5 is mounted on the core insert 1 and located between the runner and the submarine gate 31 for blocking the stub bar 101. The utility model discloses a change into submarine gate with the mould advances the runner, and the movable mould increases the mold insert (promptly, blocks mold insert 5) and blocks stub bar 101, and when slider 3 was opened, stub bar 101 can be broken, realizes automatic disconnected stub bar, and stub bar 101 can be blocked mold insert 5 and block when ejecting (as shown in fig. 4), can save the cost that the manual work removed the stub bar to can not influence the product appearance, improved the product yield.

In this embodiment, there are 2 pairs of sliders 3, and each pair of sliders corresponds to two product cavities 10, that is, the mold structure is a four-cavity mold, and 4 products 100 can be molded simultaneously. The top of the blocking insert 5 is provided with a groove 51, and the groove 51 is a part of the flow channel. When ejected, the slug will be left in the recess 51. The blocking insert 5 is located between two product cavities 10. I.e. two blocking inserts 5 are present in this embodiment.

Preferably, the blocking insert 5 is embedded between the pair of slides 3. I.e. on opposite sides of a pair of slides 3, recesses 32 are provided, half of the blocking insert 5 being received in the recess 32 of one slide 3 and the other half in the recess 31 of the other slide 3.

In the present embodiment, the submarine gate 31 on a pair of sliders 3 is on the diagonal line. It should be understood that for two product cavities 10, two submarine gates 31 may be on the same slide 3, with the other slide 3 being provided without a submarine gate.

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.
