Description

Technical Field

[0001] The invention relates to the technical field of mouse pad processing and production, and in particular to a production process of a lock-edge-free integrated mouse pad. Background Art

[0002] A mouse pad refers to a small pad placed under the mouse. It is mainly designed to prevent the mouse's photoreceptor positioning from being affected by surface reflection and refraction from special materials such as glass. It provides a plane for the mouse photoreceptor system to calculate the movement vector, making it easier for people to work.

[0003] During the processing of the current mouse pad, the fabric and the base material are sent to a hot pressing mold for hot pressing forming. After the fabric and the base material are hot pressed and formed, in order to avoid pilling at the corners of the product due to friction during long-term use, the hot pressed product needs to be edge-locked by an edge-locking machine. However, this will reduce the overall work efficiency and fail to meet production requirements. At the same time, edge-locking lines are left at the corners of the product after edge-locking, which makes it not smooth to use. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned technical deficiencies and propose a production process for an one-piece mouse pad without locking edges, so as to solve the technical problem that in order to avoid pilling at the corners of the product due to friction during long-term use, the mouse pad in the prior art needs to be locked at the edges of the hot-pressed product through a locking machine during processing and production, and the overall work efficiency is low and cannot meet the production requirements. At the same time, the corners of the product after locking have locking lines, which makes it not smooth to use.

[0005] In order to achieve the above technical objectives, the technical solution of the present invention provides a production process for a non-locking one-piece mouse pad, comprising:

[0006] Provide fabric and base material;

[0007] A hot pressing mold is provided, wherein the hot pressing mold comprises an upper mold and a lower mold, and a mold cavity is provided on the top of the lower mold;

[0008] The fabric is glued so that one side of the fabric is covered with a layer of transparent plastic film;

[0009] Cut the laminated fabric into required sizes and cover the mold cavity;

[0010] Evacuate the inside of the mold cavity so that the fabric fits on the bottom and side walls of the mold cavity;

[0011] Filling the base material into the mold cavity;

[0012] Press the upper mold onto the top of the lower mold to heat-press the fabric and the base material into shape;

[0013] After the molding is completed, the hot-pressed product inside the mold cavity is taken out, and the excess fabric at the corners of the product is cut off.

[0014] Furthermore, the inner side wall of the mold cavity is a rounded structure.

[0015] Furthermore, before pressing the upper mold onto the top of the lower mold, a release agent is sprayed on the bottom of the upper mold.

[0016] Furthermore, after the excess fabric at the corners of the product is cut off, the product is trimmed to make the corners of the product smooth.

[0017] Furthermore, the base material is one of PU, rubber or SCR.

[0018] Furthermore, when the base material is PU, when the fabric and the base material are hot-pressed, the temperature of the hot-pressing mold is 35°-45°.

[0019] Furthermore, when the base material is PU, when the fabric and the base material are hot-pressed, the time for hot-pressing the fabric and the base material is 5 minutes.

[0020] Furthermore, when the base material is rubber or SCR, the temperature of the hot pressing mold is 150° during hot pressing of the cloth and the base material.

[0021] Furthermore, when the base material is rubber or SCR, when the cloth and the base material are hot-pressed, the time for hot-pressing the cloth and the base material is 2 minutes.

[0022] The beneficial effects of the present invention include: the present invention provides a production process for an integrally formed mouse pad without locking edges. The mouse pad produced by the process has a fabric covering one side and a side wall of a base material, which can prevent pilling at the corners of the product due to friction during long-term use. Therefore, after the product is hot-pressed, there is no need to pass the hot-pressed product through a locking machine for locking edge processing, which can reduce production costs and thus improve production efficiency. At the same time, there are no locking edge lines at the corners of the product, making it smoother to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] Example 1

[0031] This embodiment provides a production process for a one-piece mouse pad without locking edges. Figure 1-5 As shown, including:

[0032] Step 1: Provide fabric 1 and base material 2, base material 1 is PU, and PU is liquid.

[0033] Step 2: Provide a hot pressing mold 3 , which includes an upper mold 31 and a lower mold 32 . A mold cavity 321 is provided on the top of the lower mold 32 , and an inner side wall of the mold cavity 321 is a chamfered structure 3211 .

[0034] Step 3: Laminating the fabric 1 so that one side of the fabric 1 is covered with a layer of transparent plastic film, while the other side of the fabric 1 can be a decorative surface.

[0035] Step 4: Cut the glued fabric 1 into the required size and cover the mold cavity 321 . When covering the mold cavity 321 , place the un-glueized side of the fabric 1 toward the bottom of the mold cavity 321 .

[0036] Step 5: Evacuate the inside of the mold cavity 321 to make the cloth 1 fit to the bottom and side walls of the mold cavity 321. Since the cloth 1 is covered with a layer of transparent plastic film on one side after lamination, it can prevent the outside air from entering the mold cavity 321 when the inside of the mold cavity 321 is evacuated, so that the cloth 1 can fit closely to the bottom and side walls of the mold cavity 321, so that the surface of the cloth 1 on the product after hot pressing is smoother.

[0037] Step six, fill the base material 2 into the mold cavity 321. Since the base material 2 is PU and PU is liquid, when the base material 2 is filled into the mold cavity 321, the PU can be injected into the mold cavity 321 through an injection machine, which is easy to operate. Since one side of the cloth 1 is covered with a layer of transparent plastic film after lamination, PU can be prevented from penetrating the entire cloth 1.

[0038] Step seven, press the upper mold 31 on the top of the lower mold 32 to make the cloth 1 and the base material 2 hot-pressed. When the cloth 1 and the base material 2 are hot-pressed, the temperature of the hot-pressing mold 3 is 35°-45°, preferably 40°, and the hot-pressing time is 5 minutes. The cloth 1 on the hot-pressed product covers one side and the side wall of the base material 2, which can avoid pilling due to friction at the corners of the product during long-term use. Therefore, after the hot-pressing of the product, there is no need to pass the hot-pressed product through the locking machine for locking treatment, which can reduce production costs and thus improve production efficiency. At the same time, the product has not been locked, and there is no locking line at the corners of the product, which is smoother to use. Moreover, the inner side wall of the mold cavity 321 is a chamfered structure, which can make the side wall of the product a chamfered structure, which is smoother to use. At the same time, the cloth 1 and the base material 2 at the corners of the product can be more firmly formed, which can avoid the separation of the cloth 1 and the base material 2 at the corners of the product when the product is in use, thereby improving the service life of the product.

[0039] Step eight, after the molding is completed, the upper mold 31 is opened, and the product formed by hot pressing inside the mold cavity 321 is taken out. Since the release agent is sprayed on the bottom of the upper mold 31 before the upper mold 31 is pressed on the top of the lower mold 32, it is easier to separate the base material 2 of the product from the upper mold 31 when the upper mold 31 is opened. After the product inside the mold cavity 321 is taken out, the excess fabric 1 at the corners of the product is cut off. After cutting the excess fabric 1 at the corners, the product is trimmed to smooth the corners of the product. The processing and production of the mouse pad can be completed, and the processed mouse pad is then packaged and stored.

[0040] Example 2

[0041] This embodiment provides a production process for a one-piece mouse pad without locking edges. Figure 1-5 As shown, including:

[0042] Step 1: Provide a cloth 11 and a base material 2, wherein the base material 2 is one of rubber and SCR, and both rubber and SCR are solid.

[0043] Step 2: Provide a hot pressing mold 3 , which includes an upper mold 31 and a lower mold 32 . A mold cavity 321 is provided on the top of the lower mold 32 , and an inner side wall of the mold cavity 321 is a rounded structure 3211 .

[0044] Step 3: Laminating the fabric 1 so that one side of the fabric 1 is covered with a layer of transparent plastic film, while the other side of the fabric 1 can be a decorative surface.

[0045] Step 4: Cut the glued fabric 1 into the required size and cover the mold cavity 321 . When covering the mold cavity 321 , place the un-glueized side of the fabric 1 toward the bottom of the mold cavity 321 .

[0046] Step 5: Evacuate the inside of the mold cavity 321 to make the cloth 1 fit to the bottom and side walls of the mold cavity 321. Since the cloth 1 is covered with a layer of transparent plastic film on one side after lamination, it can prevent the outside air from entering the mold cavity 321 when the inside of the mold cavity 321 is evacuated, so that the cloth 1 can fit closely to the bottom and side walls of the mold cavity 321, so that the surface of the cloth 1 on the product after hot pressing is smoother.

[0047] Step 6: Fill the base material 2 into the mold cavity 321. When the base material 2 is rubber, and the rubber is solid, the base material 2 needs to be processed before filling the base material 2 into the mold cavity 321. The specific steps are:

[0048] Step (1), manufacturing a rubber foam body;

[0049] Step (2), cutting the rubber foam into required specifications;

[0050] When the base material 2 is SCR, the base material 2 also needs to be processed before filling the base material 2 into the mold cavity 321. The specific processing method is the same as the processing method of the rubber mentioned above.

[0051] Step seven, press the upper mold 31 on the top of the lower mold 32 to hot-press the cloth 1 and the base material 2. When hot-pressing the cloth 1 and the base material 2, the temperature of the hot-pressing mold 2 is 150°, and the hot-pressing time is 2 minutes. The cloth 1 on the hot-pressed product covers one side and the side wall of the base material 2, which can avoid pilling due to friction at the corners of the product during long-term use. Therefore, after the hot-pressing of the product, there is no need to pass the hot-pressed product through the locking machine for locking processing, which can reduce production costs and thus improve production efficiency. At the same time, the product has not been locked, and there is no locking line at the corners of the product, which is smoother to use. In addition, the inner side wall of the mold cavity 321 is a chamfered structure, which can make the side wall of the product a chamfered structure, which is smoother to use. At the same time, the cloth 1 and the base material 2 at the corners of the product can be more firmly formed, which can avoid the separation of the cloth 1 and the base material 2 at the corners of the product when the product is in use, thereby improving the service life.

[0052] Step eight, after the molding is completed, the upper mold 31 is opened, and the product formed by hot pressing inside the mold cavity 321 is taken out. Since the release agent is sprayed on the bottom of the upper mold 31 before the upper mold 31 is pressed on the top of the lower mold 32, it is easier to separate the base material 2 of the product from the upper mold 31 when the upper mold 31 is opened. After the product inside the mold cavity 321 is taken out, the excess fabric 1 at the corners of the product is cut off. After cutting the excess fabric 1 at the corners, the product is trimmed to smooth the corners of the product. The processing and production of the mouse pad can be completed, and the processed mouse pad is then packaged and stored.

[0053] The mouse pad production process without lock-edge one-piece molding in the embodiment of the present invention adopts the mouse pad produced by the process, and the fabric 1 on the product covers one side and the side wall of the base material 2, which can prevent the corners of the product from pilling due to friction during long-term use. Therefore, after the product is hot-pressed, there is no need to pass the hot-pressed product through a lock-edge machine for lock-edge processing, which can reduce production costs and thus improve production efficiency. At the same time, there is no lock-edge line on the corners of the product, and it is smoother to use.

[0054] The specific implementation of the present invention described above does not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
