Slider horizontal core-pulling mechanism for injection mold

technical field

The utility model relates to a mechanism for an injection mold, in particular to a horizontal core-pulling mechanism for a sliding block of an injection mold which can realize core pulling in a direction perpendicular to the mold opening direction when the mold is opened to facilitate taking out workpieces.

Background technique

In the production process of injection molding products, some products with special shapes are often encountered. During the injection molding process of such products, because the product itself has holes, grooves, etc. in the direction perpendicular to the mold opening direction, Therefore, ordinary molds cannot be used for processing, but the mold needs to be divided into multiple parts according to the actual situation of the product and combined to form a molding cavity, and then it needs to be demolded in different directions. The process is complicated. The operation is cumbersome, and a new design is required for different products, which not only consumes a lot of time, but also increases the cost. Therefore need a kind of can solve the above-mentioned problem now, only need movable mold to move once and just can the mold structure that the product of this special structure is released from mould.

The specific solution of the utility model is: a slider horizontal core-pulling mechanism for an injection mold, including a static mold and a movable mold 1, and an insert 2 is fixedly arranged on the movable mold 1, and the static mold, the movable mold 1 and the insert 2 to form a product 3 in the injection molding cavity, which is characterized in that: the inner cavity of the insert 2 is provided with a traversing slider 4, and the inner side of the traversing slider 4 is provided with an inclined tenon and groove 5, and the movable mold 1 The inner slide is connected with a vertical sliding block 6, and the front end of the vertical sliding block 6 is provided with an inclined-plane convex line 7 matching the inclined-plane tenon groove 5, and a vertical sliding block limit block 10 is also provided at the rear end of the movable mold 1, A slanted hole 11 is arranged on the longitudinal sliding block 6 , and a power pin 12 is matched with the slanted hole 11 .

A spring 9 is sleeved on the bolt 8 threaded with the longitudinal sliding block 6 , and the bolt 8 can move in the hole on the limit block 10 of the longitudinal sliding block.

Compared with the prior art, the utility model has the following advantages:

The structure of this mechanism is simple and the design is ingenious. It creatively adds a horizontal core-pulling mechanism to the traditional mold, which eliminates the need to divide the mold into multiple parts during the injection molding production process of some products with special shapes and structures. Parts are combined, and the mold needs to be opened in multiple directions; it greatly saves the workload of injection molding production, improves work efficiency, and reduces the operating cost of the enterprise; and it has a reasonable structure and simple production, so it has a wide range of applications. The market prospect is very conducive to popularization and application in this field.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

Detailed ways

The specific embodiment of the utility model will be described below in conjunction with the accompanying drawings. As shown in Figure 1: a slider transverse core-pulling mechanism for an injection mold, including a static mold and a moving mold 1, an insert 2 is fixedly arranged on the moving mold 1, and the static mold, the moving mold 1 and the insert 2 are jointly The injection molding cavity is formed, and the product 3 is formed in the injection cavity; in the inner cavity of the insert 2, a traverse slider 4 is arranged (the quantity and shape of the traverse slider 4 are determined according to the actual size of the product 3 to be injection molded. situation selection), the inner side of the traversing slider 4 is provided with an inclined mortise 5, and the inclined ridge 7 matching the inclined mortise 5 is arranged on the front end of the longitudinal slider 6, and the longitudinal slider 6 is slidably connected In the moving mold 1; at the rear of the moving mold 1, there is also a longitudinal slider limit block 10 fixedly connected, which is used to limit the moving distance of the longitudinal slider 6, and the bolt 8 passes through the longitudinal slider limit block 10 is threadedly connected to the tail end of the longitudinal sliding block 6, and a spring 9 is sleeved on the bolt 8; an inclined hole 11 is provided on the longitudinal moving sliding block 6, and the top end of the power pin 12 matched with the inclined hole 11 can be connected with the Connect to an external power source (such as a hydraulic cylinder, etc.).

The working process of the slider transverse core-pulling mechanism for the injection mold of the embodiment of the utility model is as follows: firstly, the product 3 as shown in the figure needs to be processed by injection molding. Since the side of the product 3 is provided with a hole 13, during the injection molding process, a mold needs to occupy the space of the hole 13. However, when opening the mold, the mold needs to be pulled out from the hole 13 first, and then the mold can be opened. Therefore, in the process that the movable mold 1 is away from the static mold, the power source (such as a hydraulic cylinder) is pulled out of the power pin 12 upwards from the inclined hole 11, and under the action of the inclined surface, the longitudinal sliding block 6 moves backward relative to the movable mold 1 , while the traversing slider 4 connected to the end of the longitudinal slider 6 through the inclined mortise 5 and the inclined ridge 7 cannot move with the longitudinal slider 6 due to the obstruction of the movable mold 1, so it also acts on the inclined surface Next, the traversing slider 4 moves laterally relative to the insert 2, and the effect of the lateral movement is that the protrusion on the traversing slider 4 will withdraw from the hole 13 and the insert 2;

When the tail end of the vertical slide block 6 contacts with the stop block 10 of the vertical slide block, the vertical slide block 6 stops moving, and at this moment, the spring 9 is in a fully stretched state; , the insert 2 can be separated from the product smoothly, the movable mold 1 is far away from the static mold, and the product 3 can be taken out of the injection cavity.

Before the next injection molding, the power pin 12 moves downward, pushing the longitudinal sliding block 6 to move forward, and the beveled convex strip 7 slides in the beveled tenon groove 5, pushing the transverse sliding block 4 to enter the hole of the insert 2 again In the injection molding cavity, occupy the spatial position of the hole 13 on the product 3; then the movable mold 1 and the static mold are closed, and the injection molding process can be performed.

The mold with this mechanism can achieve the purpose of core pulling in both horizontal and vertical directions in one mold opening process, saving operation steps and improving production tempo.
