[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention opens a horn glue inlet on the lower mold slider of the liquid silicon mold. When the mold is closed, the upper mold slider is face-to-face with each other, so that the lower mold slider is moved to the set position, and the glue is injected into the glue inlet from the runner. After the product is filled, the excess glue overflows from the overflow glue port and is automatically cut off. The glue inlet can be manually trimmed with scissors after the product is taken out. After the employee takes out the mold, the mold is automatically cut off and only the glue inlet needs to be taken out, which reduces the product scissoring process and the risk of shearing damage. The product can be automatically ejected by the ejector, which improves the efficiency of the employees.

[0016] 2. Compared with traditional inclined guide pillars, the present invention saves more mold space. Due to the face-to-face cooperation, the risk of mold collision can be effectively avoided, and the processing cost can be effectively reduced.

[0017] 3. The mold of the present invention has changed from traditional straight glue feeding to the current ox horn glue feeding, which can achieve no obvious glue feeding point on the reverse side of the appearance, and the glue can be effectively saved

[0018] 4. The mold of the present invention positions the product by using the conventional upper and lower mold clamping method, but now the injection molded part is placed in the mold cavity, and the upper and lower molds are automatically clamped to drive the slider to move to achieve product positioning: the positioning principle is that the upper and lower molds are clamped to complete the rough positioning of the product, and then the upper mold slider drives the lower mold slider to move inward to press the plastic part through the clamping, thereby achieving fine positioning.

[0019] 5. The appearance of the product of the present invention is effectively improved. Previously, due to the lack of precise positioning of the upper and lower molds, the product would be crushed or deviate from the positioning direction, resulting in unqualified products.

[0020] 6. The present invention changes from traditional two-color injection molding + LSR injection to single-color injection, which greatly reduces the cost investment of the mold and changes from special customized equipment to conventional equipment, thereby improving the utilization rate of the equipment and reducing the equipment cost investment.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] See also Figure 1-10The present invention provides a technical solution: a waste quick cleaning mold, comprising an upper mold 3 and a lower mold 2 matched with the upper mold 3, a rectangular template 1 is installed under the lower mold 2, an upper core plate 13 is installed at the central end wall of the template 1 close to the lower mold 2, and recesses 4 are provided at the four corners of the end face of the lower mold 2. A through-hole 14 is provided through the end wall of the upper core plate 13, and a ejector pin 15 for ejecting the material is provided in the through-hole 14. A bottom core plate 17 is installed at the end wall of the upper core plate 13 away from the template 1, and sliding columns 18 are installed at the four corners of the end wall of the upper core plate 13. A spring 16 is installed on the outside of the sliding column 18, and the through-hole 14 and the ejector pin 15 are movably connected, and the through-hole 1 4. The ejector pins 15 are distributed at equal distances, and the upper core plate 13 and the ejector pins 15 are fixedly connected. The upper core plate 13 and the slide post 18 are fixedly connected, and the upper core plate 13 and the bottom core plate 17 are fixedly connected. The bottom core plate 17 and the slide post 18 are movably connected, and the slide post 18 is movably connected to the lower mold 2. When the mold is opened and closed, the upper core plate 13 moves, and drives the ejector pins 15 fixed at the end wall of the upper core plate 13 to move in the perforations 14. After the ejector pins 15 penetrate the perforations 14, they push the material and eject it, thereby discharging the material. The spring 16 is sleeved on the outside of the slide post 18, so that when the mold is opened and closed, there is spring force between the lower mold 2 and the upper mold 3, which can automatically reset.

[0036] A slide rail 5 is installed at the center end wall of the bottom of the lower mold 2, and a lower mold slider 7 is installed on the end side of the slide rail 5. The upper mold slider 6 is tightly installed on the side end of the lower mold slider 7. A lower mold slide plate 8 is installed on the top wall of the lower mold slider 7. There are four notches 4, and the notches 4 are symmetrically distributed about the center of the lower mold 2. At the same time, the upper mold slider 6, the lower mold slider 7, and the lower mold slide plate 8 are the same in number. There are four upper mold sliders 6, the lower mold slider 7, and the lower mold slide plate 8. A slide groove opening for movable connection to the slide rail 5 is opened at the bottom of the lower mold slider 7, and the top side wall of the lower mold slider 7 is inclined. At the same time, the bottom side wall of the upper mold slider 6 is inclined. The upper mold slider 6 and the lower mold slider 7 are pressed together during the mold closing process, so that the two lower mold sliders 7 and the two lower mold slide plates 8 are displaced synchronously. The two lower mold slide plates 8 are close to each other to form a clamp to position the product. The positioning principle is to first complete the rough positioning of the product when the mold is closed, and then the upper mold slider 6 drives the lower mold slider 7 to move inward to press the plastic part, so as to accurately position the product, and the appearance of the product is effectively improved. Compared with the lack of precise positioning during mold closing, it effectively reduces the occurrence of product crushing and product deviation from the positioning direction.

[0037] The left and right ends of the lower die 2 are both equipped with forming plates 9, and the end faces of the forming plates 9 are provided with plate cavities 10. The plate cavities 10 are relatively provided with glue inlets 11 and glue overflow ports 12. The inclined side walls of the upper die slider 6 and the lower die slider 7 fit together. When the upper die slider 6 and the lower die slider 7 are in contact, the lower die slider 7 is squeezed to move toward the center of the forming plate 9. The lower die 2 is fixedly connected to the slide rail 5, and the lower die 2 is movably connected to the lower die slider 7 through the slide rail 5. At the same time, the upper die slider 6 is fixedly connected to the upper die 3. The inclined end walls of the upper die slider 6 and the lower die slider 7 are set so that when the upper die slider 6 and the lower die slider 7 are in contact, they squeeze each other, so that the upper die The slider 6 squeezes the lower mold slider 7 to move sideways, thereby driving the lower mold slide plate 8 to move sideways, and then accurately positioning the product. The glue inlet 11 and the glue overflow port 12 are relatively arranged with respect to the center of the plate cavity 10. At the same time, the lower mold slide plate 8 is in the shape of a concave font, and an elliptical through hole is relatively opened at the end wall of the lower mold slide plate 8 near the concave port. When the mold is in use, the glue material is injected into the glue inlet 11 from the runner, and the excess glue overflows from the glue overflow port 12 after filling the product. After the molding is completed, the upper and lower molds are no longer in contact when the mold is opened, and the waste material at the glue inlet 11 and the glue overflow port 12 is automatically cut off when the lower mold slide plate 8 retreats, so that the product can be in a state without burrs and glue inlet 11.

[0038] In summary, when using the waste quick cleaning mold,

[0039] The lower mold 2 and the upper mold 3 are closed to roughly position the product. At the same time, during the closing process of the lower mold 2 and the upper mold 3, the upper mold slider 6 and the lower mold slider 7 are close to each other and squeezed, so that the lower mold slider 7 slides to one side along the slide rail 5 and drives the two lower mold slide plates 8 to close to finely position the product. When the upper mold slider 6 is closed, the lower mold slider 7 is driven to move inward to press the plastic part, thereby accurately positioning the product. The appearance of the product is effectively improved. Compared with the lack of precise positioning during closing, the occurrence of product crushing and product deviation from the positioning direction is effectively reduced.

[0040] When the mold is in use, the glue is injected into the glue inlet 11 from the runner. After the product is filled, the excess glue overflows from the glue overflow port 12. After the molding is completed, the lower mold 2 and the upper mold 3 are no longer in contact when the mold is opened. When the lower mold slide 8 retreats, the waste material at the glue inlet 11 and the glue overflow port 12 is automatically cut off, so that the product can be free of flash and glue inlet 11.

[0041] At the same time, when the mold is opened, the ejector pin 15 passes through the through hole 14 and ejects the product to discharge the product. The arrangement of the spring 16 and the slide column 18 allows elasticity between the lower mold 2 and the upper mold 3 to assist the mold opening and closing operations.

[0042] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
