Description

Technical Field

[0001] This application relates to the field of injection mold technology, and in particular to a resettable external refrigerator tray mold. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] like Figure 1 As shown, after the refrigerator tray mold is opened, the top-side slider 102, after being pulled out through the inclined guide post 101, needs to be maintained at a suitable height to ensure accurate engagement with the inclined guide post 101 during the next mold closing and reset. In existing technology, the slider 102 is typically supported by a nitrogen spring installed inside the mold. This has the drawback that it is only suitable for scenarios where the slider 102 has a small stroke, and requires mold disassembly for repair or replacement in case of malfunction. If a common helical spring is used, it will undergo fatigue deformation after prolonged use, and its preload cannot be adaptively adjusted, resulting in insufficient reset force. Therefore, how to improve the existing (top-side) slider 102 elastic mounting method to overcome the above problems is a problem urgently needing to be solved by those skilled in the art. Utility Model Content

[0004] One of the objectives of this application is to provide a mold for resetting an external refrigerator tray.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a reset external refrigerator tray mold, comprising a mold body, a base, a guide rod, an elastic element, and an adjustment assembly. The base is detachably installed on the outside of the mold body. The guide rod is inserted into the base and its first end is connected to the slider of the mold body. The elastic element is sleeved on the guide rod. The adjustment assembly is installed on the second end of the guide rod and cooperates with the elastic element. The adjustment assembly is adapted to adjust the compression amount of the elastic element.

[0006] Preferably, the adjusting assembly includes an adjusting screw block, which engages with the second end of the guide rod via a thread; during adjustment, the adjusting screw block is adapted to rotate spirally and move axially along the guide rod, thereby squeezing or releasing the elastic element.

[0007] Preferably, the adjusting assembly further includes a limiting screw block, which engages with the second end of the guide rod via a thread; after adjustment, the limiting screw block is adapted to rotate spirally until it abuts against the adjusting screw block.

[0008] Preferably, the vertical projection of the limiting screw block onto the base is completely located at the vertical projection of the adjusting screw block onto the base.

[0009] Preferably, a protective cylinder is installed on the outside of the base, and the elastic element and the adjusting component are both located inside the protective cylinder.

[0010] Preferably, the bottom end of the adjusting screw block is provided with a guide portion, and the guide portion forms a sliding fit with the inside of the protective cylinder.

[0011] Preferably, the outer side of the protective cylinder is provided with a slot communicating with its interior, thereby forming a visualization window for observing the elastic element.

[0012] Preferably, the slot is provided with matching mounting holes near and between the slot and the base, so that the protective cylinder can be installed on the base by fasteners.

[0013] Preferably, the slots are a pair and are symmetrically distributed along the axis of the protective cylinder.

[0014] Preferably, the first end of the guide rod is threaded into the slider, and the outer side of the guide rod near the first end has parallel concave planes, which cooperate with the working surface of the clamping tool and transmit torque.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] This invention features a base, guide rod, elastic element, and adjustment assembly. The base allows the entire structure to be detachably installed on the outside of the mold body, enabling external installation. Furthermore, the sufficient space outside the mold body allows for adaptability to large-stroke slider reset scenarios. By adjusting the compression of the elastic element through the adjustment assembly, even if the elastic element experiences fatigue deformation due to long-term use, the reduction in elastic force can be compensated by adjusting the compression, ensuring the slider always maintains a stable reset force.

[0025] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0028] One preferred embodiment of this application, such as Figures 1 to 7As shown, a reset external refrigerator tray mold includes a mold body 1, a base 2, a guide rod 6, an elastic element 4, and an adjustment component 8. The base 2 can be detachably installed on the outside of the mold body 1 by bolts. The guide rod 6 is inserted through the base 2, and the first end (bottom end) of the guide rod 6 is connected to the slider 102 (top side) on the mold body 1. The elastic element 4 is sleeved on the outside of the guide rod 6. The adjustment component 8 is installed on the second end (top end) of the guide rod 6 and cooperates with the elastic element 4 to achieve elastic connection and installation of the slider 102. The adjustment component 8 can adjust the compression amount of the elastic element 4.

[0029] It should be noted that, for horizontal injection molding machines, the terms "top side" and "bottom side" of the mold describe the installation direction of the mold on the machine platform; the top side refers to the upper part of the mold (vertical to the ground), and the bottom side refers to the lower part of the mold (vertical to the ground). The side operated by the worker is called the operating side, and the other side, which is away from the operator, is called the non-operating side or the side away from the operator. The elastic mounting structure of the slider 102 in this application is applied to the installation of the slider 102 on the top side of the refrigerator tray mold. Therefore, the vertical elastic sliding installation of the slider 102 is used as an example for specific description, but this does not constitute a limitation of this application. Those skilled in the art can also apply it to other slider 102 installation scenarios according to actual needs.

[0030] Understandably, firstly, the elastic element 4 and guide rod 6 are detachably mounted on the top exterior of the mold body 1 via the base 2, i.e., external mounting. Therefore, the elastic element 4 can be inspected or replaced without disassembling the mold, greatly simplifying the maintenance process and reducing operational difficulty and time costs. Furthermore, since it is mounted externally on the mold body 1, a suitable model of elastic element 4 can be selected to adapt to the large-stroke resetting scenario of the slider 102, effectively solving the problem of limited stroke in traditional built-in nitrogen springs. Secondly, the compression of the elastic element 4 can be adjusted by the adjusting component 8. Even if the elastic element 4 undergoes fatigue deformation due to long-term use, the reduction in its elastic force can be compensated by adjusting the compression, ensuring that the slider 102 always maintains a stable resetting force.

[0031] As a further description of the above embodiments: as Figure 4 As shown, the adjusting assembly 8 includes an adjusting screw block 801, which engages with the top of the guide rod 6 via a thread. The elastic element 4 is preferably a spring, which is sleeved outside the guide rod 6 and positioned between the adjusting screw block 801 and the base 2. During adjustment, the adjusting screw block 801 can be rotated by screwing it, causing it to move axially up and down along the guide rod 6 under the action of the thread. This compresses or releases the spring, changing its compression and thus adjusting its elastic force.

[0032] Furthermore, such as Figure 4 As shown, the adjusting assembly 8 also includes a limiting screw block 802, which is threaded into the second end of the guide rod 6. The limiting screw block 802 is located above the adjusting screw block 801. It can be understood that after the adjusting screw block 801 is adjusted, the limiting screw block 802 is rotated until it abuts against the top of the adjusting screw block 801. This locks the axial position of the adjusting screw block 801, effectively preventing it from loosening due to vibration or impact during long-term mold operation. This ensures that the compression of the elastic element 4 remains at the set value, guaranteeing the stability and reliability of the slider 102's reset.

[0033] In one embodiment of this application, such as Figure 3 and Figure 4 As shown, a protective cylinder 3 is installed outside the base 2. The elastic element 4 and the adjusting component 8 are all located inside the protective cylinder 3. That is, the protective cylinder 3 can effectively protect the elastic element 4 and the adjusting component 8, thereby improving the stability of the device. The top of the protective cylinder 3 has an open structure, which allows the operator to rotate the adjusting screw block 801 through the opening.

[0034] Based on the above embodiments, the following problems may exist during adjustment: due to the protective function of the protective sleeve 3, generally only a socket wrench can be used to rotate the two screw blocks. If each adjustment requires first disassembling the limit screw block 802, then adjusting the adjusting screw block 801, and finally reinstalling the limit screw block 802, this will make the operation complicated and affect work efficiency.

[0035] Therefore, in order to solve the above-mentioned technical problems, in this embodiment, as follows: Figure 7 As shown, the vertical projection of the limiting screw block 802 onto the base 2 is completely located on the vertical projection of the adjusting screw block 801 onto the base 2; that is, the size of the limiting screw block 802 is smaller than the size of the adjusting screw block 801.

[0036] Specifically, such as Figure 7 As shown, during adjustment, the adjusting screw block 801 is first rotated using the larger socket head of the socket wrench. At this time, the limiting screw block 802 is located inside the larger socket head and does not interfere with the rotation of the adjusting screw block 801. The adjusting screw block 801 can be adjusted directly without prior removal of the limiting screw block 802, effectively simplifying the adjustment process. After the adjusting screw block 801 is adjusted to the target position, the limiting screw block 802 is then rotated using the smaller socket head of the socket wrench, causing it to move downwards and press against the top of the adjusting screw block 801, thus completing the axial locking of the adjusting screw block 801. This design greatly improves the convenience of the adjustment operation.

[0037] Furthermore, such as Figure 4 and Figure 5 As shown, a guide portion 10 is provided at the bottom end of the adjusting screw block 801, and the guide portion 10 forms a sliding fit with the inside of the protective cylinder 3. That is to say, the outer wall of the guide portion 10 and the inner wall of the protective cylinder 3 are in abutting fit. When the adjusting screw block 801 moves axially along the guide rod 6, the guide portion 10 can play a limiting role for the top end of the guide rod 6, thereby improving the stability of the device.

[0038] In this embodiment, as Figure 3 As shown, the protective cylinder 3 has a slot 5 on its exterior that communicates with its interior, thus forming a visual window for observing the elastic element 4. Understandably, workers can directly observe the compression state, deformation degree, and surface wear of the elastic element 4 through this window, and can monitor the working status of the elastic element 4 in real time without disassembling the protective cylinder 3, facilitating the timely detection of potential faults and targeted maintenance.

[0039] Furthermore, such as Figure 4 As shown, the slot 5 is located below the protective cylinder 3 and close to the base 2, and a matching mounting hole 7 is provided between the bottom of the slot 5 and the top of the base 2, allowing the protective cylinder 3 to be detachably installed on the base 2 using bolts or other fasteners. It should be noted that in the prior art, the installation of the protective cylinder 3 requires mounting ears at its outer bottom, which increases the overall volume of the protective cylinder 3. The design of the slot 5 provides an installation space for the protective cylinder 3, and the bolts and other fasteners are also located within the slot 5, without affecting the overall appearance and size of the protective cylinder 3, making it more compact.

[0040] Furthermore, it is preferable to use a pair of slots 5, which are symmetrically distributed along the axis of the protective cylinder 3. This makes the connection between the base 2 and the protective cylinder 3 more stable. At the same time, the symmetrical design of the slots 5 also allows the staff to observe the state of the elastic element 4 from different angles. In addition, the symmetrical structure helps the protective cylinder 3 to be subjected to uniform force during installation, reducing the loosening or deformation problems caused by stress concentration on one side during long-term use.

[0041] In one embodiment of this application, such as Figure 6 As shown, the bottom end of the guide rod 6 is threaded into the slider 102. The guide rod 6 has parallel concave surfaces 9 on its outer surface near the first end, which engage with the working surface of the clamping tool and transmit torque. For example, when installing the guide rod 6, the operator can use the open end of a wrench to engage the two corresponding concave surfaces 9, and transmit torque to the guide rod 6 by rotating the wrench. This effectively avoids slippage caused by the smooth surface when directly rotating the guide rod 6, improving installation efficiency and connection reliability.

[0042] The working principle of this utility model is as follows:

[0043] First, the base 2 is installed at the top of the mold, with the guide rod 6 passing through it. The bottom end of the guide rod 6 is threadedly fastened to the slider 102. Next, the elastic element 4 is inserted through the top of the guide rod 6, and the adjusting nut is tightened onto the top of the guide rod 6, positioning the adjusting nut correctly and compressing the elastic element 4. Then, the limiting nut is installed above the adjusting nut and tightened. Finally, the protective cylinder 3 is installed on the base 2 for protection. When the mold opens, the slider 102 moves upward under the action of the inclined guide post 101, causing the guide rod 6 to move upward synchronously. At this time, the elastic element 4 limits the guide rod 6 under its elastic force, positioning the slider 102 at the upward position after mold opening, thus preparing for precise cooperation with the inclined guide post 101 during the next mold closing.

[0044] When it is necessary to adjust the compression preload of the spring, such as Figure 7 As shown, firstly, the larger socket head of the socket wrench is inserted into the protective sleeve 3, and then the adjusting screw block 801 is rotated to move it down to the appropriate position. Then, the smaller socket head of the socket wrench is used to rotate the limiting screw block 802, causing it to move down and press against the top of the adjusting screw block 801, thus completing the axial locking of the adjusting screw block 801 and completing the adjustment.

[0045] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
