Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model provides a manual bush mould, specifically refer to FIG. 1, its difference with prior art lies in: the manual bush mould comprises a group of upper and

lower templates

6 and 5 which are matched with each other, a plurality of groups of cavities are arranged between the upper and lower templates, 2-5 groups of cavities which are parallel are usually arranged, each group of cavities comprises a product pouring cavity 21 and a side sliding block placing cavity 22 arranged at one end of the product pouring cavity, the end part of the product pouring cavity extends to the side sliding block placing cavity, a core rod is arranged in the product pouring cavity and the side sliding block placing cavity in a penetrating mode, the side sliding block placing cavity is provided with a side sliding block matched with the core rod, the side sliding block placing cavity comprises an upper and a lower template which are arranged on the upper and a lower side sliding block, a sliding cavity position 23 for the side sliding block to move is arranged in the lower side sliding block placing cavity, one end of the core rod is provided with a drawing end extending to the outside of the bush mould, and the drawing end is provided with a core rod lock and a core rod rotating shaft 91.

When the side sliding block is used, the end part of a poured product does not form a parting line any more, secondary processing on the end face of the product is not required to be performed difficultly, the product precision and the production efficiency are improved, and the production cost is reduced.

Example 1

In this embodiment, manual bush mould includes a set of upper and lower bolster of mutually supporting, on, be equipped with 2 sets of cavities that set up side by side between the lower bolster, every group die cavity includes the product pouring chamber and places the chamber with the side slider of establishing in product pouring chamber one end, the product pouring chamber is placed the intracavity with the side slider and is run through and place a plug, the side slider is placed the intracavity and is equipped with the side slider with plug complex, the plug runs through the side slider and sets up, the side slider of lower module is placed the intracavity and is reserved the slip cavity position that supplies the side slider motion, the one end of plug is equipped with the pull end that extends to the outside of bush mould, the lower part of pull end is equipped with the plug lock, one side of plug is equipped with the plug axis of rotation.

Specifically, the side sliding block comprises a sliding block body and a sliding block pressing block 81 matched with the sliding block body, an embedded sliding block spring 82 is arranged on the sliding block body, the sliding block spring is arranged at the lower position of the sliding block body, and the side part of the sliding block pressing block is tightly attached to and matched with the position of the sliding block spring. The sliding block pressing block is fixed on the lower die plate through screws and has the function of ensuring that the sliding block slides in the direction of the core rod when sliding out, and the product is prevented from being damaged by pulling and deforming.

Slider body one end is equipped with and places the slotted hole with product pouring cavity complex product, the other end is equipped with the unilateral angle hole that is 2 degrees with plug matched with, 2 degree angle hole and product placing slot hole UNICOM, the product is placed the slotted hole and is 1-5 with the depth ratio in 2 degree angle holes, the setting of slotted hole is placed to the product, make the terminal surface of product laminate with the inner wall of side slider completely, the parting line can not appear in the outward appearance terminal surface of guaranteeing the pouring back product, need not carry out secondary operation to the outer terminal surface of product, the process steps have been reduced, the product appearance precision has been improved, and the cost is reduced. Particularly, set up 2 degrees angle holes, firstly, the angle cooperation makes things convenient for the plug to pull out, is difficult to the card extremely, and the second can guarantee simultaneously that the plug is followed when inserting 2 degrees angle holes once more the slider body and is advanced, accomplishes reset work.

Example 2

The die cavity that sets up side by side is equipped with a plurality of groups between the upper and lower module of this scheme, and every group die cavity includes product pouring chamber and establishes and place the chamber at the side slider of product pouring chamber one end, and product pouring chamber and side slider are placed the intracavity and are run through and place the plug, and the side slider is placed the intracavity and is equipped with the slidable side slider with plug complex, because side slider and plug closely cooperate for bush product shaping rear end face does not have the parting line, has saved secondary operation's process, the cost is reduced.

Furthermore, one end of the sliding block body is a plane, is connected with the product pouring cavity and is partially overlapped; the other end is divided into an upper module contact part 83 and a lower module contact part 84 by taking the upper end edge of the hole with the angle of 2 degrees as a boundary, the upper module contact part is an inclined plane and is abutted against the upper module, when the upper module is pressed down to be matched, the upper module contact part is limited and locked by the upper module, the lower module contact part is a plane, a sliding cavity position 23 exists between the lower module and the upper module, after the upper module is opened, the limiting locking to the slider body is cancelled, the slider body can slide and move along the sliding cavity position under the action of a slider spring, the limiting of the side slider to a product is further eliminated, the product is conveniently ejected under the action of an ejector pin, and the product 13 is taken out.

In this embodiment, the lower mould bottom plate is equipped with to the below of lower bolster, is equipped with the thimble board on the lower mould bottom plate, is equipped with the thimble on the thimble board, and the top of thimble links to each other with the product pouring chamber. The ejector plate is connected with the lower die base plate through the ejector base plate, a group of symmetrically arranged lower die mold feet are arranged on two sides of the ejector base plate respectively, and a lower die plate is arranged at the top of each lower die mold foot. The upper part of the upper template is provided with upper template feet, and the two sides of the upper template are provided with handles 12 which are symmetrically arranged.

This device is after the pouring is accomplished, carries out the die sinking, then is pulled out by manual after the plug rotates 90 degrees, when the plug was pulled out, 5mm behind the automatic retreat of side slider under the effect of slider spring, then the thimble is followed the below and is pushed out, makes things convenient for the product to take out. Specifically, the core rod is provided with a notch at the position corresponding to the core rod lock, and when the core rod is rotated and the notch is opposite to the core rod lock, the core rod can be pulled out; when the core rod rotates again, the notch is in a locking state when facing back to the core rod lock, and the core rod cannot be pulled out. The specification of the slider spring is TF6 x 10, when the mandrel inserted in the slider body is pulled out, the slider loses the forward stress, and automatically retreats for 5mm along the pulling-out direction of the mandrel under the elastic force of the spring, so that the end face parting of the product is completed.

Further, after the product is taken out, the core rod is inserted into the 2-degree angle hole again, then the core rod is pushed forwards continuously, the side sliding blocks return at the same time, the core rod rotates for 90 degrees again after the side sliding blocks return, the core rod lock rotates to lock the core rod, then the mold is closed, and the next pouring process is waited.

The foregoing is a more detailed description of the invention, taken in conjunction with the accompanying preferred embodiments, and it is not intended that the invention be limited to the specific embodiments described above.
