Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to an injection mold for a coffee machine foot cup. Background Technology

[0002] Coffee machines, common appliances in modern homes and offices, typically have several feet installed at their base. These feet primarily serve to support the machine, adjust its level, and provide anti-slip and shock absorption. To meet the demands of large-scale production, these feet are usually mass-produced using injection molding. The production efficiency and mold stability directly impact the cost and quality of the final product.

[0003] In the actual assembly process of coffee machines, different sizes or structures of feet are often required to accommodate the machine's bottom structure and leveling needs. Commonly, on the same coffee machine, some feet require pre-embedded metal threaded rods for height adjustment, while others are simple, fixed structures without pre-embedded parts. However, existing injection molds are usually designed for single-specification products; that is, a single mold can only produce feet with threaded rods or only standard feet.

[0004] This single-function mold design shows significant shortcomings when facing the need to produce coffee machine foot cups in sets of different sizes. Manufacturers typically need to develop two sets of molds and produce simultaneously on two injection molding machines, or frequently change molds on the same injection molding machine for alternating production. This not only significantly increases the manufacturing cost of the mold and the occupancy rate of the injection molding equipment, leading to a cumbersome production process and extended cycle, but also makes it difficult to achieve the synchronous production of foot cups of different sizes, severely restricting overall production efficiency. Therefore, a coffee machine foot cup injection molding mold is proposed to solve the above problems. Utility Model Content

[0005] In view of the problems in the existing technology of coffee machine foot cup injection molding molds, such as the single function of the mold, the difficulty in simultaneously molding foot cups with embedded parts and ordinary foot cups in the same mold, resulting in cumbersome production process, high equipment occupancy rate and low production efficiency, this utility model aims to provide a coffee machine foot cup injection molding mold with improved structure that can simultaneously mold two different specifications of foot cups in one injection process and effectively ensure the precise positioning of the embedded parts.

[0006] This utility model provides an injection molding mold for a coffee machine foot cup, including an mounting plate, a fixing plate, a sliding plate, an ejector pin, a fixing seat, a molding mechanism, and a mold closing assembly.

[0007] The molding mechanism mainly includes a bottom mold, a shaped block, and a fixed column, while the mold closing assembly mainly includes an injection plate and a top mold.

[0008] The mounting plate serves as the basic mounting platform for the entire mold. A fixed plate is fixedly connected to its top. The fixed plate has a hollow frame structure to support and accommodate the internal moving parts. The sliding plate is slidably connected to the internal cavity of the fixed plate, and several vertically upward ejector pins are fixedly installed on its top. The ejector pins are used to eject the molded product.

[0009] A fixing seat is fixedly connected to the top of the fixing plate, and a molding mechanism is installed inside the fixing seat. The core of the molding mechanism is the bottom mold. The bottom mold has two molding grooves, one for molding different sizes of foot cups, and an injection flow channel connecting the two molding grooves is also provided on the top of the bottom mold to guide the molten plastic.

[0010] To provide reliable positioning for the pre-embedded threaded rod in the molding groove, irregular blocks are fixedly installed on both sides of the fixing seat, and fixing columns are fixedly connected to the sides of the irregular blocks. The fixing columns are horizontally inserted into the bottom mold and extend into the molding groove to provide lateral support and fixation for the pre-embedded threaded rod during injection molding, ensuring its positional accuracy.

[0011] A mold clamping assembly is located above the molding mechanism. The mold clamping assembly is mounted on the injection molding machine via an injection plate. An injection tube is installed in the middle of the injection plate, which is used to guide the molten material into the injection flow channel. The top mold is installed at the bottom of the injection plate. The top mold has a protrusion that mates with the first molding groove and a concave hole that mates with the second molding groove. This convex-concave structure enables precise closure of two cavities of different specifications.

[0012] Preferably, the fixed plate has a hollow frame structure, the sliding plate is located inside the cavity formed by the fixed plate, and the side wall of the sliding plate and the inner wall of the fixed plate are in close sliding fit to ensure the stability and guidance of the ejection mechanism.

[0013] Preferably, the injection flow channel is located at the center of the upper surface of the bottom mold and branches outwards in all directions. The ends of the injection flow channel extend to the edges of the first molding channel and the second molding channel, respectively. This layout design aims to balance the flow channels to the greatest extent, shorten the filling time, and improve the uniformity of the product.

[0014] Preferably, the injection tube penetrates vertically through the injection plate, and the bottom outlet of the injection tube precisely corresponds to the center confluence of the injection flow channel, ensuring reliable connection and sealing between the injection machine nozzle and the mold flow channel inlet. The injection tube is firmly fixed to the injection plate by means of threaded connection or flange connection.

[0015] Preferably, the irregular block is fixedly connected to the mounting groove on the outer wall of the fixing seat by bolts, which facilitates installation, disassembly and maintenance. In addition, two fixing columns are provided at intervals along the height direction of the forming groove, which provides more stable and reliable dual-point lateral fixing support for the embedded part.

[0016] Preferably, the protrusion has a ring-shaped structure, the outer diameter of the protrusion is adapted to the inner diameter of the molding groove, and several venting grooves are opened on the periphery of the protrusion so that the air inside the cavity can be smoothly discharged when the mold is closed, avoiding the formation of bubbles or burning in the product.

[0017] Preferably, the number of ejector pins corresponds to the total number of the first molding groove and the second molding groove, and the bottom of the first molding groove and the second molding groove are provided with through holes for the ejector pins to pass through, so as to realize the synchronous and efficient ejection of multi-cavity products.

[0018] Preferably, the molding groove is configured to accommodate a pre-embedded threaded rod, the fixing column is configured to fix the pre-embedded threaded rod, and the mold closing assembly is configured to slide towards the molding mechanism under the drive of the injection molding machine to achieve mold closing. Its overall functional design is to improve the co-mold production capability of products with different specifications.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model solves the problem in the prior art that different specifications of coffee machine foot cups need to be produced by changing different molds or using multiple sets of molds in the prior art. It achieves the technical effect of simultaneously molding two different specifications of products in one injection molding process, significantly shortening the production cycle, reducing equipment investment costs and improving production efficiency.

[0021] 2. This utility model solves the problem that the embedded parts are prone to shaking, shifting or even tipping due to the impact of high pressure molten material during injection molding by setting irregularly shaped blocks with fixing columns on both sides of the fixed seat. The fixing columns are horizontally inserted into the bottom mold and extend into the forming groove to abut against the pre-embedded threaded rod. This achieves the technical effect of accurately positioning and firmly supporting the embedded parts, effectively ensuring the product dimensional accuracy and yield rate.

[0022] 3. This utility model, by adopting a top mold structure composed of protrusions and concave holes, respectively cooperates with the forming groove one and forming groove two on the bottom mold for mold closing, solves the problem of difficulty in uniformly closing and forming different structural cavities, and achieves the technical effect of compact mold structure, good mold closing sealing, and adaptability to the molding needs of diverse products, thereby improving the versatility and practicality of the mold.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] Reference Figures 1 to 4 This utility model provides an injection molding mold for coffee machine feet, which aims to solve the problem that in the prior art, a single mold is difficult to mold coffee machine feet of various specifications at the same time, resulting in low production efficiency.

[0032] A coffee machine foot cup injection molding mold includes a mounting plate 1, which serves as the mounting base for the entire device. A fixing plate 2 is fixedly connected to the top of the mounting plate 1. The fixing plate 2 is used to support and install the internal sliding plate 3. The fixing plate 2 has a hollow frame structure.

[0033] The sliding plate 3 is slidably connected to the inside of the fixed plate 2 and is used to achieve up-and-down reciprocating motion under the drive of the ejection mechanism of the injection molding machine. Several vertically upward ejector pins 4 are fixedly installed on the top of the sliding plate 3. The ejector pins 4 are used to eject the molded product and demold it.

[0034] A fixed base 5 is fixedly connected to the top of the fixed plate 2. The fixed base 5 is used to install and fix the core forming part of the mold. The forming mechanism 6 is installed inside the fixed base 5. The top of the ejector pin 4 passes through the bottom of the fixed base 5 and extends into the interior of the forming mechanism 6. A mold closing assembly 67 that can realize the up and down opening and closing action is provided above the forming mechanism 6. The mold closing assembly 67 is used to cooperate with the forming mechanism 6 to form a closed mold cavity. After the injection molding machine is started, it will drive the mold closing assembly 67 to slide closer to the forming mechanism 6 to realize mold closing.

[0035] The molding mechanism 6 includes a bottom mold 61 installed inside the fixed base 5. The bottom mold 61 has a molding groove 63 and a molding groove 65 for molding different sizes of foot cups. The top of the bottom mold 61 also has an injection flow channel 66 for uniformly introducing molten plastic into each molding groove. The fixed base 5 has irregular blocks 62 fixedly installed on both sides. A fixing post 64 is fixedly connected to one side of the irregular block 62. The fixing post 64 is horizontally inserted into the bottom mold 61 and its end extends into the molding groove 63 for lateral fixing of the pre-embedded threaded rod. The mold closing assembly 67 includes an injection plate 674 and a top mold 671 installed inside the injection plate 674. An injection tube 675 is installed in the middle of the injection plate 674. The top mold 671 has a protrusion 673 that mates with the molding groove 63 and a concave hole 672 that mates with the molding groove 65.

[0036] The bottom mold 61, as the core component of the lower mold, integrates both molding groove 1 63 and molding groove 2 65. Molding groove 1 63 is configured to accommodate pre-embedded threaded rods, while molding groove 2 65 is configured to mold ordinary foot cups. Through the integrated arrangement of these two grooves, simultaneous production of two products in a single injection molding operation is achieved. The injection flow channel 66 is located at the center of the upper surface of the bottom mold 61 and branches outwards in a radiating pattern. Its ends extend and connect to the edges of molding groove 1 63 and molding groove 2 65, respectively. The injection flow channel 66 ensures that the molten plastic can be filled simultaneously and evenly. To ensure that the pre-embedded threaded rods in each molding groove do not shake or shift under high injection pressure, the irregular block 62 is fixedly connected to the outer walls of both sides of the fixing seat 5 by bolts. Two fixing posts 64 are fixedly connected to the side of the irregular block 62 facing the bottom mold 61, which are distributed vertically at intervals. The fixing posts 64 pass horizontally through the side wall of the fixing seat 5 and are inserted into the bottom mold 61, with their ends extending into the molding groove 63. The fixing posts 64 abut against the pre-embedded threaded rods, thereby providing lateral support and positioning for the threaded rods during the injection molding process, ensuring the dimensional accuracy of the product.

[0037] The mold closing assembly 67 serves as the upper mold part. An injection tube 675 is vertically installed through the middle of the injection plate 674. The bottom outlet of the injection tube 675 precisely corresponds to the center confluence of the injection flow channel 66 on the bottom mold 61, which is used to guide the molten material from the injection molding machine into the mold flow channel device. The top mold 671 is installed on the bottom of the injection plate 674. A protrusion 673 is provided on the bottom surface corresponding to the first molding groove 63. The protrusion 673 has a ring-shaped structure and its outer diameter is adapted to the inner diameter of the first molding groove 63. When the mold is closed, the protrusion 673 is inserted above the first molding groove 63 to close the mold cavity. At the same time, the top mold 671 has a concave hole 672 corresponding to the second molding groove 65. The inner diameter of the concave hole 672 is adapted to the outer diameter of the second molding groove 65. When the mold is closed, the concave hole 672 is engaged above the second molding groove 65, together forming a complete molding space for another shaped foot cup. Through this convex-concave fit design, the molding requirements of different product structures are met.

[0038] In a preferred embodiment, the injection flow channel 66 is designed to be located at the center of the upper surface of the bottom mold 61 and is distributed in a cross shape. Each end of the injection flow channel 66 extends and connects to the edge of the first molding channel 63 and the second molding channel 65, respectively. This layout shortens the flow channel and reduces pressure loss. The bottom outlet of the injection tube 675 corresponds precisely to the central confluence of the injection flow channel 66, and the injection tube 675 is firmly fixed to the injection plate 674 by means of threaded connection or flange connection to prevent leakage during high-pressure injection. The irregular block 62 is fixedly connected to the mounting groove opened in the outer wall of the fixing seat 5 by bolts. At the same time, two fixing columns 64 are provided at intervals along the height direction of the first molding channel 63, which can provide more stable dual-point support and effectively prevent the pre-embedded threaded rod from tilting.

[0039] In a preferred embodiment, the protrusion 673 has a ring-shaped structure, and its outer diameter is adapted to the inner diameter of the first molding groove 63. Several venting grooves are opened on the periphery of the protrusion 673. The inner diameter of the concave hole 672 is adapted to the outer diameter of the second molding groove 65 to ensure the mold closing accuracy. The fixed plate 2 has a hollow frame structure. The sliding plate 3 is located inside the cavity formed by the fixed plate 2 and the mounting plate 1. The two sides of the sliding plate 3 are fitted and slidably engaged with the inner wall of the fixed plate 2. Guide pillars for resetting are also provided through the four corners of the sliding plate 3. The number of ejector pins 4 corresponds one-to-one with the total number of the first molding groove 63 and the second molding groove 65. Each first molding groove 63 and the second molding groove 65 has an ejector pin hole at the bottom for the ejector pin 4 to pass through. The first molding groove 63 and the second molding groove 65 are distributed in a rectangular array on the bottom mold 61 to maximize the use of mold space and increase the single injection production.

[0040] The implementation principle of this application embodiment is as follows: First, the operator installs the device on the injection molding machine through the mounting plate 1 and the injection plate 674. After the injection molding machine is started, it will drive the mold closing assembly 67 to slide closer to the molding mechanism 6 to realize mold closing, merge the bottom mold 61 and the top mold 671, and start the injection molding process.

[0041] A fixing plate 2 is fixed to the top of the mounting plate 1. The function of the fixing plate 2 is to facilitate the installation of the sliding plate 3. The sliding plate 3 slides inside the fixing plate 2, which in turn drives the ejector pin 4 fixed to the top of the sliding plate 3 to slide, pushing out the molded foot cup. A fixing seat 5 is installed on the top of the fixing plate 2. The fixing seat 5 facilitates the installation and fixing of the bottom mold 61 and the irregular block 62 inside. A molding groove 1 63 and a molding groove 2 65 are opened inside the bottom mold 61 to realize the molding of two different shapes of foot cups in one mold. An injection flow channel 66 is opened on the top of the bottom mold 61 to facilitate the uniform entry of molten material into the bottom mold 61. Before injection molding, the threaded rod needs to be placed inside the molding groove 1 63. Irregular blocks 62 are fixedly installed on both sides of the fixing seat 5. Two irregular blocks 62 are fixed on one side of each irregular block 62. Two fixing posts 64 are inserted into the bottom mold 61 to fix the threaded rods pre-embedded inside the forming groove 63. The molten material is transported to the injection tube 675 through the injection molding machine and then enters the injection flow channel 66 for uniform injection molding. The injection tube 675 is installed in the middle of the injection plate 674. The top mold 671 is installed inside the injection plate 674. The top mold 671 has a concave hole 672 and a protrusion 673 inside. When the mold is closed, the protrusion 673 merges with the corresponding forming groove 63, and the concave hole 672 merges with the corresponding forming groove 65, finally forming two shapes of foot cups. This realizes the simultaneous injection molding of two specifications of coffee machine foot cups in one injection, with high dimensional accuracy, simplified production process and improved production efficiency, while ensuring stable and reliable mold operation, and adapting to the needs of mass production.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
