Description

Technical Field

[0001] The utility model relates to the field of plastic molds, in particular to a plastic mold capable of rapid casting. Background Art

[0002] Plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low-foaming molding. The coordinated changes of the mold convex and concave molds and the auxiliary molding system can process a series of plastic parts of different shapes and sizes.

[0003] When using a vertical plastic injection mold, it is usually necessary to remove the molded part and then close the mold again to inject plastic, which cannot achieve fast pouring, thereby reducing production efficiency.

[0004] To solve the above problems, the present application proposes a plastic mold capable of rapid casting. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In order to solve the technical problems existing in the background technology, the utility model proposes a plastic mold that can be quickly poured. The utility model drives the turntable to rotate by a driving motor, so as to replenish the lower mold in time. After pouring, the lower mold is subjected to the centrifugal force of the rotating turntable to throw out the internal molded parts, and at the same time cooperates with the knocking mechanism to increase the effect of separating the molded parts.

[0007] (II) Technical solution

[0008] In order to solve the above problems, the utility model provides a plastic mold capable of rapid casting, comprising an upper mold and a lower mold, wherein the lower mold is connected to a turntable;

[0009] The turntable is rotatably connected to a mounting frame via a rotating shaft, and a driving motor is fixedly connected to the mounting frame;

[0010] The rotating disk is provided with a knocking mechanism which knocks the lower mold as the rotating disk rotates.

[0011] Preferably, the knocking mechanism comprises a sleeve and a knocking ball, the sleeve is fixedly mounted on the side of the turntable, and the knocking ball is placed inside the sleeve.

[0012] Preferably, the outer periphery of the striking ball is fixedly covered with a rubber sleeve.

[0013] Preferably, the knocking ball is connected to the inner wall of the sleeve through an elastic rope.

[0014] Preferably, a driving member is fixedly mounted on the mounting frame, and a driving rod of the driving member is connected to the upper mold.

[0015] Preferably, the driving member is a hydraulic cylinder or a pneumatic cylinder.

[0016] The above technical solution of the utility model has the following beneficial technical effects:

[0017] The driving part drives the upper mold to move toward the lower mold to facilitate the injection of plastic through the upper mold. After the injection is completed, the driving part drives the upper mold to separate from the lower mold. At this time, the driving motor is started, and the driving motor drives the turntable to rotate to drive the lower mold to rotate away from the upper mold. Another lower mold is added to the bottom of the upper mold in time for rapid pouring. The separated lower mold is separated from the molded parts inside the lower mold under the action of centrifugal force and the impact of the knocking ball on the lower mold, which increases the convenience of unloading and facilitates injection molding again.

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] like Figure 1-2 As shown, the utility model provides a plastic mold capable of rapid casting, comprising an upper mold 1 and a lower mold 2, wherein the lower mold 2 is connected to a turntable 3;

[0023] The turntable 3 is rotatably connected to a mounting frame 4 via a rotating shaft, and a driving motor 5 is fixedly connected to the mounting frame 4;

[0024] The turntable 3 is provided with a striking mechanism 6 for striking the lower mold 2 as the turntable 3 rotates.
