Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold with a local edge opening. Background Art

[0002] Molds are essential tools used to shape objects in industrial production. They impart specific shapes and structures to raw materials, imparting them with specific shapes and dimensions. Molds come in a wide variety of types, including injection molds, stamping molds, and die-casting molds. Mold precision is crucial in the manufacturing process, directly impacting product quality and performance. High-quality molds ensure precise dimensions, smooth surfaces, and stable structures. Mold design and manufacturing require specialized expertise and experience, encompassing materials science, machining, CAD / CAM technology, and other fields.

[0003] The use of molds has improved production efficiency and achieved large-scale, standardized production. It is widely used in industries such as automobiles, electronics, home appliances, and plastic products, making an important contribution to the development of modern industry.

[0004] After processing the product, the existing mold often has local overflow and produces burrs. The product after demoulding needs secondary processing to remove the burrs before it can be used, which increases the processing steps. Utility Model Content

[0005] In order to overcome the above technical problems, the utility model provides a mold with a partial edge opening, so as to improve the problem of burrs when the mold is ejected.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes a mold with a local edge opening, including a mold box and a mold cover, wherein the opening of the mold box is formed with a plurality of shielding plates extending upward from the inner wall of the mold box, and gaps are formed between the plurality of shielding plates, and the mold cover is formed with a plurality of cutting blades, each of the cutting blades corresponding to one of the gap positions.

[0007] Multiple shielding plates are installed at the opening of the mold box, with gaps between them. During the molding process, the material usually exceeds the volume of the molded product. During the molding process, when the mold cover is pressed down, the excess material will overflow. Where the shielding plates are installed, the material cannot overflow and can only flow out through the gaps between the shielding plates, which is equivalent to a fixed channel for the material to flow out. Multiple cutting blades are installed on the mold cover, and the position of the cutting blades corresponds to the gaps. When the mold cover is pressed down, the cutting blades will cut the last seeping material when the mold cover is about to be completely covered. When the mold cover is completely covered, the cutting blades completely cut off the overflowing material. When the product is demoulded, the burrs are completely eliminated by the cutting blades, and the product is formed in one go.

[0008] Preferably, a first slide rail is formed at the opening of the mold box, and the baffle is slidably connected to the mold box through the first slide rail; a second slide rail is formed on the mold cover, and the cutting blade is slidably connected to the mold cover through the second slide rail.

[0009] A first slide rail is installed on the mold box, and a baffle is placed within it. The baffle can slide along the first slide rail. The sliding displacement of the baffle can control the position of the gap between the gaps, thereby controlling the location of the spilled material. The location of the spilled material can be equipped with a storage device to receive the spilled material, ensuring that the spilled material is accurately collected during discharge. A second slide rail is installed on the mold cover, and the cutting blade can also move to the position to match the gap between the baffles to cut the spilled material.

[0010] Preferably, flexible shielding strips are respectively provided on both sides of the upper opening of the first slide rail and are arranged along the length direction of the first slide rail. The flexible shielding strips extend from both sides of the upper opening of the first slide rail to the middle and intersect with each other.

[0011] Flexible shielding strips are provided on both sides of the first slide rail to cover the upper surface of the first slide rail from both sides. This ensures that when the material overflows due to being pressed down by the mold cover, the material will not penetrate into the first slide rail, thereby protecting the slide rail.

[0012] Similarly, the second slide rail can also be provided with a flexible shielding strip to prevent the inflow of materials.

[0013] Preferably, the cutting blade is connected to the mold cover via an elastic device.

[0014] The cutting disc is connected to the mold cover through an elastic device. When cutting overflowing materials, it will not be cut into place at once, but will be slowly pressed down by elastic force. This can protect the cutting disc from breaking due to rigid contact.

[0015] Preferably, the cutting edge of the cutting blade forms an angle with the opening of the mold box.

[0016] The cutting edge of the cutting blade forms an angle with the opening of the mold box. When the mold cover is pressed down, the cutting blade cuts into place on one side first, leaving a gap on the other side where the material can continue to overflow. Until the mold cover is pressed down again, the pressure of the overflowing material is completely released, and the high edge of the cutting blade forming the angle is not excessively squeezed by the overflowing material.

[0017] Preferably, the elastic device is a spring respectively provided at both ends of the cutting blade.

[0018] A spring is set at each end of the cutting blade. The spring can play a role of longitudinal elastic pressure and partial lateral offset elastic force. For the cutting blade that forms an angle with the opening of the mold box, it can play a role of partial offset deformation to help the cutting blade cut downward.

[0019] The mold with partial edge opening provided by the utility model can guide the overflow position of the internal material when being squeezed by arranging a shielding plate at the opening of the mold box, and cut the overflowing material by the cutting piece at the corresponding position on the mold cover, so that the burrs are eliminated when the product is formed, and the product is formed in one time without the need for subsequent trimming processing.

[0029] A first slide rail 5 is provided on the mold box 1, and a baffle 3 is placed within it. The baffle 3 can slide along the first slide rail 5. The sliding displacement of the baffle 3 controls the position of the gap between the baffles, thereby controlling the location of the spilled material. A storage device can be used to receive the spilled material at the location of the spilled material, ensuring that the spilled material is accurately collected during discharge. A second slide rail is provided on the mold cover 2, and the cutting blade 4 can also be moved to the gap between the baffles 3 to cut the spilled material.

[0030] In one embodiment of the present invention, flexible shielding strips are respectively provided on both sides of the upper opening of the first slide rail 5 along the length direction of the first slide rail 5 , and the flexible shielding strips extend from both sides of the upper opening of the first slide rail 5 to the middle and intersect.

[0031] Flexible shielding strips are provided on both sides of the first slide rail 5 to cover the upper surface of the first slide rail 5 from both sides. This ensures that when the material overflows due to being pressed down by the mold cover 2, the material will not penetrate into the first slide rail 5, thereby protecting the slide rail.

[0032] Similarly, the second slide rail can also be provided with a flexible shielding strip to prevent the inflow of materials.

[0033] In one embodiment of the present invention, the cutting blade 4 is connected to the mold cover 2 via an elastic device.

[0034] The cutting blade 4 is connected to the mold cover 2 through an elastic device. When cutting overflowing materials, it will not be cut into place at once, but will be slowly pressed down by elastic force, which can protect the cutting blade 4 from breaking due to rigid contact.

[0035] In one embodiment of the present invention, the cutting edge of the cutting blade 4 forms an angle with the opening of the mold box 1 .

[0036] The cutting edge of the cutting blade 4 forms an angle with the opening of the mold box 1. When the mold cover 2 is pressed down, the cutting blade 4 cuts into place on one side first, leaving a gap on the other side where the material can continue to overflow. Until the mold cover 2 is pressed down again, the pressure of the overflowing material is completely released, and the high edge of the cutting blade 4 formed by the angle is not excessively squeezed by the overflowing material.

[0037] In one embodiment of the present invention, the elastic device is a spring 6 respectively provided at both ends of the cutting blade 4 .

[0038] A spring 6 is set at both ends of the cutting blade 4. The spring 6 can play a role of longitudinal elastic pressure and partial lateral offset elastic force. For the cutting blade 4 that forms an angle with the opening of the mold box 1, it can play a role of partial offset deformation to help the cutting blade 4 cut downward.

[0039] The mold with partial edge opening provided by the utility model can guide the overflow position of the internal material when being squeezed by arranging a baffle plate 3 at the opening of the mold box 1, and cut the overflowing material by the cutting piece 4 at the corresponding position on the mold cover 2, so that the burrs are eliminated when the product is formed, and the product is formed in one time without the need for subsequent trimming processing.
