Description

Mold locking device

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

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

In the forming process, in order to prevent the upper mold from being separated from the lower mold, after the user closes the upper mold and the lower mold, the buckle is fastened to the upper mold and the lower mold to prevent the upper mold and the lower mold from being separated. 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 formed material.

However, when the upper mold and the lower mold are opened, hot air is ejected from between the upper mold and the lower mold, which is liable to cause burns to the user. In view of this, it is necessary to improve the problem of burns caused by the upper mold and the lower mold.

The purpose of the novel is to solve the problem that the upper mold and the lower mold are easy to cause the burnt of the personnel, thereby making the processing more safe.

In order to solve the foregoing problems, the present invention is a locking device for a mold, which is suitable for a mold having an upper mold and a lower mold which are pivotally coupled, and the lower mold extends to the upper mold in a vertical direction. The locking device of the mold comprises: a driving device fixedly disposed on the mold, the driving device has a driving rod that moves along the vertical direction; a pivot rod is disposed on the upper mold; and a fastening rod Provided in the lower mold; a pivoting member, one end of which is pivotally disposed on the driving rod, and the other end is pivotally disposed on the pivoting rod, and a buckle portion is extended between the two ends of the pivoting member; thereby, the mold is The locking device has a snapping state, a tripping state and a mold opening state; in the snapping state, the driving rod is contracted, and the upper die is attached to the lower die, so that the driving rod drives the pivoting member Swinging, the buckle is fastened to the fastening rod; in the tripping state, the driving rod extends along the vertical direction, the pivoting member is driven by the driving rod to pivot the pivoting member The position of the driving rod is pivoted, thereby releasing the buckle from the fastening rod; in the mold opening state The drive rod extends along the vertical direction, the driving plate drives the mold on the rotating pivot open.

In a preferred embodiment, the driving device has a body and a driving rod extending from one end of the body, and the driving rod is provided with a driving pivot hole opposite to the other end of the body, the pivoting member One end of the pivoting member defines a first pivot hole, and the other end of the pivoting member defines a second pivot hole. A bolt is pivotally disposed on the first pivot hole and the driving pivot hole to enable the driving device and the pivoting member. Have one The first pressing force has a second urging force between the pivoting member and the pivoting rod, and the first urging force is less than the second urging force.

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

Since the user can directly open the upper mold and the lower mold by the driving device and take out the finished product without directly facing and opening the mold by manual, the present invention can achieve the fastening state and the trip state only by the driving device. And the three states of the mold opening state not only make the overall structure simple, but also solve the problem that the upper mold and the lower mold are easy to cause the burn of the person when the mold is opened, thereby making the processing process more safe.

Referring to FIG. 1 to FIG. 2 , the present invention is a locking device for a mold, which is suitable for a mold 10 . The mold 10 has a top mold 11 and a lower mold 12 pivotally coupled to each other. The lower mold 12 extends to the upper mold. The direction of the 11 is a vertical direction Y, and the locking device of the mold comprises: a driving device 20 fixedly disposed on the mold 10, the driving device 20 having a driving rod 21 that moves repeatedly along the vertical direction Y In the embodiment, the driving device 20 is a pressure cylinder, and the driving device 20 has a body 22 and the driving rod 21, and one end of the body 22 is connected to a fixing member. 30, the fixing member 30 is fixed on the mold 10, the main body 22 of the driving device 20 is fixed on the mold 10, and the driving rod 21 is extended from the other end of the main body 22 connecting the fixing member 30. And the movement is repeated along the vertical direction Y. Since the structure in which the cylinder is actuated is a conventional technique, it will not be described herein.

A pivoting rod 40 is disposed on the upper mold 11; a fastening rod 50 is disposed on the lower mold 12; a pivoting member 60, one end of which is pivotally disposed on the driving rod 21, and the other end of which is pivotally disposed on the pivoting rod 40 A driving portion 21 is disposed between the two ends of the pivoting member 60. In the embodiment, the driving rod 21 is provided with a driving pivot hole 211 opposite to the other end of the body 22, and one end of the pivoting member 60 is opened. There is a first pivot hole 62. The other end of the pivoting member 60 defines a second pivot hole 63. A bolt 70 is pivotally mounted on the first pivot hole 62 and the driving pivot hole 211 to enable the driving device 20 and the pivot. There is a first pressing force between the rotating members 60. In the embodiment, the pivoting member 40 is provided with an octagonal circumferential surface 41, and the user can change the octagonal circumferential surface 41 of the pivoting rod 40 by a wrench to change The degree of urgency between the pivoting member 60 and the pivoting member 40 has a second urging force between the pivoting member 60 and the pivoting member 40, 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 pivoting member 60 pivots to the driving rod 21 first.

The above is the structural configuration and the connection relationship of the novel embodiment in a preferred embodiment. The manner of use of the present invention is as follows: Referring to FIG. 3 to FIG. 5, the locking device of the mold has a snap-fit state Q1. a tripping state Q2 and a mold opening state Q3; referring to FIG. 3, after the user injects the forming material into the lower mold 12, the driving device 20 is driven to cause the new type to be in the engaged state Q1. The driving rod 21 of the device 20 is contracted, and the driving rod 21 drives the upper mold 11 to fit the lower mold 12, thereby driving the pivoting member 60 to pivot, so that the pivoting member 60 is pivotally connected to the driving rod 21. Pivoting the center, and then engaging the buckle portion 61 with the fastening rod 50; The driving rod 21 is contracted so that the fastening portion 61 of the pivoting member 60 does not disengage from the fastening rod 50, so that the upper mold 11 and the lower mold 12 are stably fitted without opening.

Referring to FIG. 4, after the forming material is formed, the user first removes the pivoting member 60 from the engaged upper mold 11 and the lower mold 12, and changes from the engaged state Q1 to the tripped state Q2. The driving rod 21 extends along the vertical direction Y. The pivoting member 60 is driven by the driving rod 21 to pivot the pivoting member 60 at the position of the driving rod 21, thereby releasing the buckle portion 61. The buckle rod 50; referring to FIG. 5, after the buckle portion 61 of the pivoting member 60 is disengaged from the fastening rod 50, the user must open the upper mold 11 and the lower mold 12, and change from the trip state Q2. For the mold opening state Q3, the driving rod 21 continues to extend along the vertical direction Y. The driving rod 21 drives the upper mold 11 to pivot open, and the user can directly from the opened upper mold 11 and The lower mold 12 takes out the finished product without directly facing and opening the mold 10 by the manual. The present invention can achieve the three states of the fastening state Q1, the tripping state Q2, and the mold opening state Q3 only by the driving device 20. The overall structure is simple, and the solution to the scald of the upper mold 11 and the lower mold 12 is easily solved, thereby further improving the processing process. Safety.
