Abstract

A locking device for mould, which includes a buckling state, a releasing state and a mould opening state, in the buckling state, a driving rod shrinks, an upper mould fits a lower mould, the driving rod drives a pivot element to swing so as to make a locking portion locked with a locking rod, in the releasing state, the driving rod extends out vertically, the pivot element pivots at the position in which the pivot element is pivoted by the driving rod, thereby releasing the locking portion from the locking rod, in the mould opening state, the driving rod extends out vertically, the driving rod drives and opens the upper mould, therefore, the user do not need to directly open the upper and lower moulds, which can solve the problem that the direct opening of the upper and lower moulds can easily lead to the loss of human scalding, thus making the processing process safer.

Description

Locking device of mold

The invention relates to the field of molds, in particular to a locking device for molds.

Generally, the sole forming mold mainly has an upper mold and a lower mold. During the forming process, the user injects forming materials into the lower mold, and then covers the upper mold to form the forming materials in the lower mold into a complete sole.

In the forming process, in order to prevent the upper mold and the lower mold from detaching, after closing the upper mold and the lower mold, the general user will buckle a fastener on the upper mold and the lower mold to prevent the upper mold and the lower mold from detaching Missing.

After the forming is completed, the user must first open the buckle and then open the upper mold to take out the sole formed from the forming material.

However, when the upper and lower molds are opened, hot air will be sprayed from between the upper and lower molds, which may easily cause burns to the users. In view of this, it is indeed necessary to improve the problem of personnel burns when the upper and lower molds are opened.

The purpose of the present invention is to solve the problem that the upper mold and the lower mold are easy to cause scalds when opening, so as to make the processing process safer.

In order to solve the aforementioned problems, the present invention is a mold lock device, which is suitable for a mold, which has an upper mold and a lower mold which are pivotally coupled, and the direction in which the lower mold extends to the upper mold is a vertical direction, and The locking device of the mold includes: a driving device fixedly arranged on the mold; the driving device has a driving rod which moves repeatedly in the vertical direction; a pivot rod is arranged on the upper mold; and a locking rod , Located on the lower mold; a pivoting member, one end of which is pivotally mounted on the driving rod, and the other end is pivotally mounted on the pivot rod, a buckle extending between the two ends of the pivoting member; thereby, the mold The locking device has a buckled state, a tripped state and a mold opening state; in the buckled state, the driving rod is contracted, the upper mold is attached to the lower mold, so that the driving rod drives the pivoting member to pivot Pendulum to buckle the buckle portion to the buckling lever; when in the tripped state, the driving lever extends along the vertical direction, the pivoting member is driven by the driving lever, and the pivoting member is pivotally arranged on the The position of the driving rod pivots, so that the buckle part is disengaged from the buckling rod; in the mold opening state, the driving rod extends along the vertical direction, and the driving rod drives the upper mold to pivot open.

In a preferred embodiment, the driving device has a body and the driving rod, the driving rod extends from one end of the body, the driving rod is provided with a driving pivot hole opposite to the other end of the body, and the pivoting member A first pivot hole is opened at one end of the shaft, a second pivot hole is opened at the other end of the pivoting member, a bolt penetrates the first pivot hole and the driving pivot hole, and the pivot hole is pivotally installed in the first through a bolt A pivot hole and The driving pivot hole enables the driving device to be pivotally connected to the pivoting member with a first pressing force therebetween, and a second pressing force between the pivoting member and the pivot rod, the first pressing force is less than the Second urgency.

In a preferred embodiment, the pivot rod is provided with an octagonal peripheral surface.

Since the user can directly open the upper mold and the lower mold through the driving device and take out the finished product without directly facing and opening the mold by humans, the present invention can achieve the locked state and the released state only by the driving device And the three states of mold opening state, not only makes the overall structure simple, but also solves the lack of personnel burns when the upper and lower molds are opened, thereby making the processing process safer.

Please refer to FIG. 1 to FIG. 2, the present invention is a mold locking device, which is suitable for a mold 10 which has an upper mold 11 and a lower mold 12 which are pivotally connected, and the lower mold 12 extends to the upper mold The direction of 11 is a vertical direction Y, and the locking device of the mold includes: a driving device 20 fixed on the mold 10, the driving device 20 has a driving rod 21 that repeatedly moves along the vertical direction Y In this embodiment, the driving device 20 is a pressing cylinder, the driving device 20 has a body 22 and the driving rod 21, one end of the body 22 is connected to a fixing member 30, the fixing member 30 is fixed on the mold 10, so that the body 22 of the driving device 20 is fixed on the mold 10, and the driving rod 21 extends from the other end of the body 22 connected to the fixing member 30 And it moves repeatedly along the vertical direction Y. Since the structure of the pressing cylinder is a conventional technology, it will not be repeated here.

A pivot rod 40 is provided on the upper mold 11; a snap rod 50 is provided on the lower mold 12; a pivoting member 60, one end of which is pivotally mounted on the driving rod 21, and the other end is pivotally mounted on the pivot rod 40 , A buckle portion 61 extends between the two ends of the pivoting member 60; in this embodiment, the driving rod 21 is provided with a driving pivot hole 211 opposite to the other end of the body 22, one end of the pivoting member 60 is opened There is a first pivot hole 62, a second pivot hole 63 is opened at the other end of the pivoting member 60, and a bolt 70 is pivotally installed in the first pivot hole 62 and the driving pivot hole 211, so that the driving device 20 and the pivot There is a first pressing force between the rotating members 60; in this embodiment, the pivot rod 40 is provided with an octagonal peripheral surface 41, and the user can rotate the octagonal peripheral surface 41 on the pivot rod 40 with a wrench to further change The degree of urgency between the pivoting member 60 and the pivot lever 40 makes the pivoting member 60 and the pivot lever 40 have a second urging force, and the first urging force is less than the second urging force, so that When the driving rod 21 moves along the vertical direction Y, the place where the pivoting member 60 is pivotally connected to the driving rod 21 will first pivot.

The above is the structural configuration and connection relationship of the present invention in a preferred embodiment. The usage of the present invention is as follows:
