Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a box cover mold. Background Art

[0002] A foaming mold is a tool used to produce foam plastic products. It uses a specific processing method to make the plastic raw material form countless tiny bubbles inside the mold, thereby obtaining a lightweight foam plastic product with a certain strength. The foaming process is to fill the foaming resin into the mold, heat it to a molten state, and form a gas-liquid saturated solution. After these bubble cores expand, foam plastic parts are made. Among them, the foaming mold is an indispensable tool in the plastic foaming process. Its design and use directly affect the quality and production efficiency of the foam plastic product. However, the grooves or complex structures inside the box cover mold in the prior art will make the plastic part close to the mold during the molding process, making it difficult to demold. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the utility model provides a box cover mold, including a bottom plate, a rectangular lifting plate and a module;

[0005] A guide rod and a convex mold are fixedly arranged on the top wall of the bottom plate, and the guide rod is located on one side of the convex mold;

[0006] The rectangular lifting plate is set on the bottom plate and slidably arranged on the guide rod. The opposite side walls of the rectangular lifting plate are fixedly provided with cylinders. The piston rod of the cylinder is fixedly connected to the bottom plate. The rectangular lifting plate is provided with a through groove, which can be sleeved on the convex mold.

[0007] The bottom wall of the module is provided with a mold cavity and a guide hole, the bottom wall of the module is erected on a rectangular lifting plate, and the guide rod is slidably sleeved in the guide hole;

[0008] Among them, two rotating shafts are rotatably arranged on one side of the module, one end of each rotating shaft is fixedly provided with a toggle plate, and the other end is connected to a driving member for driving the rotation thereof, and the two toggle plates are located on both sides of the inner side of the mold cavity.

[0009] In a preferred solution, the number of cylinders is four, and the four cylinders are arranged in a matrix on both sides of the rectangular lifting plate.

[0010] In a preferred solution, the number of guide rods and guide holes are both four, and the two correspond one to one. The four guide rods are arranged in a rectangular array on the bottom plate and arranged on the periphery of the through slot.

[0011] In a preferred solution, the driving member is a motor, the base of the motor is fixedly connected to the module, and the output shaft is coaxially connected to the rotating shaft, and the output shaft of the motor corresponds to the rotating shaft one by one.

[0012] In a preferred solution, the module is a rectangular block.

[0013] The beneficial effects of the above scheme are:

[0014] The foaming resin is filled in and heated to a molten state to form a gas-liquid saturated solution located in the convex mold and the mold cavity. Further, the gas-liquid saturated solution is heated to expand the bubble cores and squeeze each other to form a foam plastic box cover. When the foam plastic box cover needs to be demolded, in the initial state, the rectangular lifting plate is in contact with the bottom plate and the module, driving the cylinder to work, and the piston rod of the cylinder begins to extend. The piston rod of the cylinder is placed on the top of the bottom plate, causing the rectangular lifting plate to start moving upward. At this time, the foam plastic box cover is attached to the mold cavity and separated from the convex mold, driving the two driving parts to work. The driving parts drive the two toggle plates to rotate through the rotating shaft, and the toggle plates to toggle the foam plastic box cover. The foam plastic box cover is separated from the mold cavity, the module is lifted to separate from the rectangular lifting plate, and the foam plastic box cover is taken out. This structural setting improves the efficiency of separating the foam plastic box cover from the mold. BRIEF DESCRIPTION OF THE DRAWINGS
