Description

Technical Field

[0001] This utility model relates to the technical field of mouse shell molding apparatus, specifically to a mouse shell molding apparatus. Background Technology

[0002] The mouse shell is a component that protects the internal electronic components and provides a comfortable tactile experience for the user. It has a free-form surface shape and internal reinforcing ribs, screw posts, side clips, and various functional holes. It is commonly mass-produced using injection molding. During injection molding, molten plastic is injected into a sealed cavity formed by a male and female mold, and after cooling and solidification, the desired shell shape is obtained.

[0003] For simple, single-color mouse shells, a single injection mold consisting of a male and female mold is typically used for one-time molding. However, for complex mouse shells or those with special requirements such as two-color designs or a combination of hard and soft rubber, two independent injection molding processes are generally employed. In existing technology, the mainstream method for achieving this two-stage molding is as follows: First, the base part of the product is injection molded using a first dedicated mold. After cooling, it is removed manually or by a robotic arm and transferred to a second independent mold for a second injection molding process to form additional parts or cover with soft rubber. During this process, the two molds must operate on two separate injection molding machines, or sequentially on a single injection molding machine by changing the molds.

[0004] However, the time required for cooling, transferring, and repositioning the semi-finished products between the two molding processes prevents continuous production and results in low equipment utilization. During transfer, manual handling of the semi-finished products not only increases labor intensity and production costs but also increases the risk of product defects or mold damage due to operational errors. Furthermore, the two molding processes require two independent sets of molds and corresponding positioning and handling systems, occupying more equipment resources and production space. Utility Model Content

[0005] The present invention aims to provide a molding device for mouse shells, which integrates two molding processes into one molding device, thereby improving the product quality and production efficiency of mouse shells.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A molding device for a mouse shell includes a male mold and a female mold that match each other. The male mold includes a male template and a male mold frame, and the female mold includes a female template and a female mold frame. There are two male molds and two female molds. The male template has a male template mounting groove, and two male mold cores are symmetrically arranged in the male template mounting groove. The female template has a female template mounting groove, and two female mold cores are symmetrically arranged in the female template mounting groove. The female mold cores installed on the two female templates have different structures. The male mold cores are respectively connected with the two types of female mold cores to form two different cavities.

[0007] The principles and advantages of this scheme are: 1. Two coupled male molds and two different female molds are set up, and a rotating mechanism is used to switch the workstations of the two male molds, realizing the synchronous operation of the first injection molding and the second injection molding process. Each mold closing can produce a finished mouse shell and a semi-finished mouse shell, effectively eliminating the time spent waiting for the first semi-finished part to cool, transfer and re-mold in the traditional secondary injection molding, improving the output per unit time. Moreover, the two male molds exchange workstations after rotating 180°, realizing the automatic transfer of the semi-finished mouse shell to the next process, realizing uninterrupted assembly line production and reducing production downtime.

[0008] 2. The rotating mechanism automatically completes the station interchange between the two public molds, replacing the steps of manually or robotically picking up and transferring semi-finished products to another set of molds in the traditional process, reducing labor intensity and the risk of positioning errors or product damage caused by manual operation.

[0009] 3. By using two injection molding processes, mouse shells with more complex structures and better performance can be produced. For example, the first injection molding can form the basic structure of the mouse shell, while the second injection molding can add special materials or structures to achieve better grip, anti-slip effect, or enhance the strength of the shell. It can also produce two-color mouse shells to meet diverse product needs.

[0010] Preferably, as an improvement, the two male molds are mounted on a rotating mechanism, which drives the two male molds to rotate for switching workstations.

[0011] Technical effect: The above-mentioned configuration of this solution integrates two independent male molds into a rotatable unit, which can automatically and accurately exchange the positions of the two male molds, realizing the rapid switching of the male mold carrying the semi-finished product from the first molding position to the second molding position.

[0012] Preferably, as an improvement, the male mold plate mounting groove is provided with an ejector pin, and the male mold core is provided with a through hole that matches the ejector pin.

[0013] Technical effect: With the above settings, the ejector pin passes through the through hole on the male mold core, which can smoothly and reliably eject the finished mouse shell, realizing the automated demolding of the finished mouse shell after molding.

[0014] Preferably, as an improvement, the master mold core includes a first mold core, a second mold core, a third mold core, and a fourth mold core, wherein the first mold core, the second mold core, and the third mold core are all slidably connected to the fourth mold core, and the first mold core, the second mold core, and the third mold core are respectively located in three different positions of the fourth mold core.

[0015] Technical benefits: The above-mentioned settings facilitate the formation or release of complex cavity structures, enabling the molding of mouse shells with complex geometric shapes such as side concavities, undercuts, and multi-directional curved surfaces, thus expanding the process adaptability of the mold.

[0016] Preferably, as an improvement, the fourth mold core is provided with a plurality of guide sliders, which are slidably connected to the first mold core, the second mold core, and the third mold core, respectively.

[0017] Technical effect: With the above settings, the guide slider provides precise guidance and support for the sliding of the first mold core, the second mold core, and the third mold core, ensuring the smoothness, straightness, and repeatability of the movement of the first mold core, the second mold core, and the third mold core during the mold opening and closing process.

[0018] Preferably, as an improvement, the mother template mounting groove is provided with limiting grooves that cooperate and connect with the first mold core, the second mold core, and the third mold core.

[0019] Technical effect: The above-mentioned settings provide the first mold core, the second mold core, and the third mold core with a limit perpendicular to the direction of movement, which can withstand the lateral pressure during injection molding, prevent the mold core from being displaced, and ensure the dimensional stability of the cavity under high pressure.

[0020] Preferably, as an improvement, the mother template mounting groove is provided with multiple cores, and the mother template core is provided with through holes that match the cores.

[0021] Technical effect: The above settings are used to generate product holes on the mouse shell and ensure the dimensional accuracy, shape consistency and positional accuracy of the product positions.

[0022] Preferably, as an improvement, the mother mold frame is provided with a plurality of wedge blocks, and the plurality of wedge blocks penetrate the mother mold template and are slidably connected to the first mold core, the second mold core, and the third mold core respectively.

[0023] Technical effect: The above-mentioned configuration in this solution uses wedge blocks to drive the synchronous opening and closing motion of the first mold core, the second mold core, and the third mold core, which can overcome the clamping force between the mold core and the product and achieve smooth mold opening of complex cavities.

[0024] Preferably, as an improvement, the inclined surface of the wedge block is provided with a slider of T-shaped structure, and the first mold core, the second mold core, and the third mold core are all provided with T-shaped grooves that cooperate and connect with the slider.

[0025] Technical effect: The above-mentioned configuration in this solution, with the sliding connection between the T-shaped slider and the T-shaped groove, can not only stably transmit driving force, but also prevent the mold core from detaching from the wedge block during movement.

[0026] Preferably, as an improvement, the female template is provided with a limiting block that cooperates with the wedge block, the limiting block is provided with a blind groove that matches the wedge block, and the male template is provided with a clearance groove for avoiding the limiting block.

[0027] Technical effect: The above-mentioned settings in this solution limit the maximum stroke of the wedge block by the blind groove on the limit block, effectively preventing the wedge block from overtravel due to operational errors or mechanism failures, thereby avoiding collision damage between the female mold core and the male mold; the clearance groove on the male mold plate ensures that the protection mechanism can work normally during mold closing and does not interfere with each other.

Detailed Implementation

[0038] The following detailed description illustrates the specific implementation method: Example The basics are as follows: Figure 1-9 As shown: The mouse shell molding device includes matching male and female molds. The male mold includes a male template 1 and a male mold frame 2, and the female mold includes a female template 3 and a female mold frame 4. There are two male molds and two female molds. The two male molds have the same structure, while the two female molds have different structures, namely a first female mold and a second female mold. The two male molds are coupled to the two female molds respectively for two injection molding processes. The male template 1 is provided with a male template mounting groove 11, and two male mold cores 5 are symmetrically arranged in the male template mounting groove 11. The female template 3 is provided with a female template mounting groove 31, and two female mold cores 7 are symmetrically arranged in the female template mounting groove 31. The female mold cores 7 installed on the two female templates 3 have different structures. The male mold cores 5 are respectively connected with the two types of female mold cores 7 to form two different cavities. The male mold cores 5 of the male mold are coupled to the female mold cores 7 of the first female mold and the female mold cores 7 of the second female mold respectively, and are sequentially subjected to the first and second injection molding processes to produce the mouse shell.

[0039] Two male molds are mounted on a rotating mechanism (not shown in the figure). The rotating mechanism drives the two male molds to rotate so as to switch their work positions. That is, the rotating mechanism drives the two male molds to rotate 180° along their center line so that the two male molds can switch their work positions.

[0040] The male mold has an ejector pin 6 installed in the male mold plate mounting slot 11. The male mold core 5 has a through hole that matches the ejector pin 6, allowing the ejector pin 6 to pass through the through hole and eject the mouse shell, which has undergone two molding processes, out of the male mold core 5. The male mold frame 2 has a drive mechanism for driving the extension and retraction of the ejector pin 6. The product injection molded by the male mold and the first female mold is a semi-finished mouse shell. After the male mold is rotated by the rotating mechanism, it undergoes a second injection molding process with the second female mold to form the finished mouse shell. The ejector pin 6 ejects the finished mouse shell out of the male mold core 5 for easy removal.

[0041] The female mold core 7 includes a first mold core 71, a second mold core 72, a third mold core 73, and a fourth mold core 74. The first mold core 71, the second mold core 72, and the third mold core 73 are all slidably connected to the fourth mold core 74. The first mold core 71, the second mold core 72, and the third mold core 73 are located in three different positions on the fourth mold core 74. The fourth mold core 74 is provided with multiple guide sliders 741, which are slidably connected to the first mold core 71, the second mold core 72, and the third mold core 73. The female mold core mounting groove 31 is provided with limiting grooves that cooperate with the first mold core 71, the second mold core 72, and the third mold core 73. The first mold core 71, the second mold core 72, and the third mold core 73 slide along the guide sliders 741 in the limiting grooves. When the first mold core 71, the second mold core 72, and the third mold core 73 slide simultaneously to fit against the fourth mold core 74, they together form the female mold core 7 coupled with the male mold core 5.

[0042] The mother template mounting groove 31 is provided with multiple cores 8, and the mother mold core 7 is provided with through holes that match the cores 8. The multiple cores 8 pass through the mother mold core 7 and are located in the cavity to form the product holes on the mouse shell.

[0043] The master mold frame 4 is provided with multiple wedge blocks 9, which penetrate the master mold template 3 and are slidably connected to the first mold core 71, the second mold core 72, and the third mold core 73 respectively. Simultaneously, the wedge blocks 9 are slidably connected to the master mold template 3. A T-shaped slider 91 is provided on the inclined surface of the wedge block 9. The first mold core 71, the second mold core 72, and the third mold core 73 are all provided with T-shaped grooves that mate with the slider 91. The master mold frame 4 and the master mold template 3 are connected by a hydraulic mechanism. The hydraulic mechanism is used to drive the master mold frame 4 and the master mold template 3 to separate and engage. When the master mold template 3 approaches the master mold frame 4, the multiple wedge blocks 9 engage with the first mold core 71, the second mold core 72, and the third mold core 73 respectively, and the T-shaped slider 91 on the wedge block 9 is slidably connected to the T-shaped groove, allowing the first mold core 71, the second mold core 72, and the third mold core 73 to slide along the inclined surface of the wedge block 9. However, due to the first mold core 71, the second mold core 72, and the third mold core 73 sliding along the inclined surface of the wedge block 9, the first mold core 71, the second mold core 72, and the third mold core 73 are not fully engaged. The third mold core 73 is restricted by the limiting groove and the guide slider 741, which causes the first mold core 71, the second mold core 72, and the third mold core 73 to move closer to the fourth mold core 74 along the limiting groove and the guide slider 741 until they fit together to form the mother mold core 7. When the mother mold plate 3 moves away from the mother mold frame 4, the wedge block 9 moves in the direction of separating from the mother mold plate 3, which causes the first mold core 71, the second mold core 72, and the third mold core 73 to move away from the fourth mold core 74 along the limiting groove and the guide slider 741.

[0044] The female template 3 is provided with a limiting block 32 that is connected to the wedge block 9. The limiting block 32 is provided with a blind groove that matches the wedge block 9 to limit the maximum displacement of the wedge block 9 and prevent the wedge block 9 from moving excessively and causing damage to the male template. The male template 1 is provided with a relief groove 12 for avoiding the limiting block 32.

[0045] In actual use, the male mold is driven by the drive mechanism to move towards the female mold until the male and female molds align and fit together, forming a cavity for producing the mouse shell. At this point, molten plastic is injected into the cavity through the injection port on the first female mold for the first injection molding, forming a semi-finished mouse shell. Then, the male mold moves away from the female mold, and the semi-finished mouse shell moves with the male mold core 5. At this time, the two female mold plates 3 and the female mold frame 4 also separate from each other, and the worker can remove the injection-molded material from the gap between the female mold plate 3 and the female mold frame 4 of the first female mold. Next, driven by the rotating mechanism, the two male molds rotate 180° as a whole, so that the two male molds interchange positions. The male mold core 5 with the semi-finished mouse shell is aligned with the female mold core 7 of the second female mold. Then the male mold moves towards the female mold again until the male mold and the female mold are aligned and fit together. At this time, plastic liquid is injected into the cavity through the injection port on the second female mold. At the same time, plastic liquid is injected into the cavity through the injection port on the first female mold. The second female mold and the male mold cooperate to perform a second injection molding of the semi-finished mouse shell to form the finished mouse shell. At the same time, the first female mold and another male mold cooperate to perform a first injection molding to form a semi-finished mouse shell. Next, the male mold moves away from the female mold, and the finished mouse shell and the semi-finished mouse shell move with the male mold cores 5 of the two male molds respectively. At this time, the two female mold plates 3 and the female mold frame 4 separate from each other. The worker can take out the injection molded sprue from the gap between the female mold plates 3 and the female mold frame 4 of the first female mold and the second female mold. At the same time, the ejector pins 6 of the male mold opposite the second female mold work to push out the finished mouse shell, and the worker can then remove the finished mouse shell. Then, the rotating mechanism drives the two male molds to rotate for the next injection molding.

[0046] In this embodiment, when the two male molds and female molds are aligned and fitted at one time, that is, when the molds are closed at one time, the first injection molding of a mouse shell and the second injection molding of a semi-finished mouse shell are completed. The finished mouse shell is directly removed, and the semi-finished mouse shell needs to be rotated by the two male molds for a second injection molding, and so on.

[0047] Furthermore, in this embodiment, a removal device can be used for auxiliary material handling. When the mold is opened, the robotic arm drives the removal device to rotate, so that the gripping mechanism of the removal device removes the finished mouse shell. The clamping mechanism of the removal device extends between the mother template 3 and the mother mold frame 4 to clamp and remove the sprue generated during the injection molding of the mouse shell.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
