Description

Technical Field

[0001] The utility model relates to the technical field of foaming molds, in particular to an overflow-proof foaming mold. Background Art

[0002] The mold for foam molding is a plastic foaming mold. The foaming resin is directly filled into the mold, which is heated and melted to form a gas-liquid saturated solution. Through nucleation, a large number of tiny bubble nuclei are formed, and the bubble nuclei grow to make foam plastic parts.

[0003] At present, the existing foaming mold usually includes an upper template and a lower template. When a mold product needs to be made: the foaming resin is filled into the lower template, the upper template is attached to the lower template, and the foaming resin is waited for foaming and molding, so that the mold product can be made.

[0004] In the above scheme, if the mold closing pressure is unstable or the foaming mold is severely worn during mold closing, the sealing effect of the contact surface between the upper mold and the lower mold will be reduced, which will lead to overflow during the foaming process. Subsequently, the staff will need to cut off the burrs formed by the overflow, thereby reducing the processing efficiency. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide an anti-overflow foaming mold. By providing a pressing mechanism and an anti-overflow component, it is ensured that overflow will not occur, and the problem of overflow during mold closing in the existing technology is solved. As a result, there is no need for workers to cut off burrs formed by overflow, thereby improving processing efficiency.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A foaming mold that prevents overflow includes an upper mold part and a lower mold part. The upper mold part includes a movable upper mold head and an upper mold plate. The lower mold part includes a lower mold. The upper mold plate is rotatably connected to the upper end of the lower mold. Corresponding mold cavities are respectively formed on the side walls of the upper mold head and the lower mold. A pressing mechanism is provided at the upper end of the upper mold plate, and an anti-overflow component is provided at the upper end of the lower mold. Multiple buckles are installed on the side walls of the lower mold.

[0008] When it is necessary to make a mold product, fill the foaming resin into the mold groove of the lower mold, drive the upper mold plate to flip, so that the upper mold plate and the upper mold head are pressed against the upper end of the lower mold, buckle, start the pressing mechanism, press the four sides of the upper mold head downward, and continue to apply downward pressure on the upper mold head, so that the sides of the upper mold head can fit tightly against the upper end of the lower mold to ensure that there will be no overflow, and under the action of the anti-overflow component, the material that may overflow is blocked, thereby further ensuring that there will be no overflow.

[0009] By providing a pressing mechanism and an anti-overflow component, it is ensured that overflow will not occur, which solves the problem of overflow during mold closing in the prior art. As a result, there is no need for workers to cut off burrs formed by overflow, thereby improving processing efficiency.

[0010] The utility model is further configured as follows: the movable upper die head includes multiple first compression springs fixed on the upper end of the upper die head, the four sides of the upper die head rest against the inner wall of the upper template, and the upper end of the first compression spring is fixed on the inner wall of the upper template.

[0011] Through the above technical solution, when the upper template and the upper die head are pressed against the upper end of the lower die, under the action of multiple first compression springs, a downward pressure will be continuously applied to the upper die head, so that the upper die head can be tightly pressed against the upper end of the lower die.

[0012] The utility model is further configured as follows: the pressing mechanism includes a pressing plate and a pressing assembly, the pressing plate includes four pressing rods inserted into the upper end of the upper template, the four pressing rods are respectively located on the four sides of the upper die head, the upper ends of the four pressing rods are fixed with the same connecting plate, and the pressing assembly is arranged at the upper end of the upper template.

[0013] Through the above technical solution, when it is necessary to press the four sides of the upper die head downward, the pressing assembly is started to drive the connecting plate to move downward. The downward movement of the connecting plate also drives the four pressing rods to move downward, thereby pressing the four sides of the upper die head downward.

[0014] The utility model is further configured as follows: the pressing assembly includes a threaded tube fixed to the upper end of the connecting plate, a threaded rod is screwed into the threaded tube, and the threaded rod passes through the protruding end of the connecting plate and is rotatably connected to the upper end of the upper template.

[0015] Through the above technical solution, when the connecting plate needs to be moved, the threaded rod is driven to rotate, and the rotation of the threaded rod drives the threaded tube to move, thereby driving the connecting plate to move.

[0016] The utility model is further configured as follows: the overflow prevention component includes a corrugated protrusion fixed to the upper end of the lower mold, and the lower end of the upper mold head is formed with a corrugated groove that cooperates with the corrugated protrusion.

[0017] Through the above technical solution, when the upper template and the upper die head are pressed against the upper end of the lower die, the corrugated protrusions and the corrugated grooves are simultaneously fitted together, thereby blocking possible overflow of material.

[0018] The utility model is further configured as follows: a second compression spring is inserted into the side wall of the pressure rod, the lower end of the second compression spring is fixed to the side wall of the pressure rod, and the upper end of the second compression spring is fixed to the inner wall of the upper template.

[0019] Through the above technical solution, when the four pressing rods press the upper die head, the second compression spring is provided to apply downward pressure to the pressing rods, so that the four pressing rods can better press the four sides of the upper die head.

[0020] The beneficial effects of the utility model are:

[0021] Compared with the existing technology, the pressure mechanism and the anti-overflow component are provided to ensure that overflow will not occur, which solves the problem of overflow during mold closing in the existing technology. As a result, there is no need for workers to cut off the burrs formed by the overflow, thereby improving processing efficiency.

[0022] By providing the corrugated protrusions and the corrugated grooves, the material that may overflow can be blocked.

[0023] By providing the second compression spring, downward pressure can be applied to the pressing rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] By providing a pressing mechanism and an anti-overflow component, it is ensured that overflow will not occur, which solves the problem of overflow during mold closing in the prior art. As a result, there is no need for workers to cut off burrs formed by overflow, thereby improving processing efficiency.

[0034] The movable upper die head 1 includes a plurality of first compression springs 6 fixed to the upper end of the upper die head 1 . The four sides of the upper die head 1 abut against the inner wall of the upper mold plate 2 , and the upper ends of the first compression springs 6 are fixed to the inner wall of the upper mold plate 2 .

[0035] When the upper mold plate 2 and the upper die head 1 are pressed against the upper end of the lower mold 3, under the action of multiple first compression springs 6, a downward pressure is continuously applied to the upper die head 1, so that the upper die head 1 can be tightly pressed against the upper end of the lower mold 3.

[0036] The pressing mechanism includes a pressing plate and a pressing assembly. The pressing plate includes four pressing rods 7 inserted into the upper end of the upper template 2.
