Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to a mold for plastic processing. Background Technology

[0002] A mold is a tool used to make shaped objects. This tool is made up of various parts, and different molds are made up of different parts. The mold is mainly composed of two parts: the bottom shell of the mold and the top cover of the mold. When using it, the molten plastic solution is poured into the mold, and then after the plastic solution in the mold solidifies, the top cover of the mold can be opened to take out the molded plastic product inside.

[0003] A Chinese patent application (or patent) with publication number CN220883036U discloses a plastic processing mold, including a base. A first press lock is fixedly connected to one end of the top of the base, and the other end of the press lock is fixedly connected to the mold. A bottom rod is fixedly connected to the top of the base, a first lock is slidably connected to the outer wall of the bottom rod, and a second lock is fixedly connected to the top of the bottom rod. A pressing column is fixedly connected to the bottom of the mold, and a wedge-shaped slider is slidably connected inside the pressing column. A sliding rod is fixedly connected to the outer wall of the wedge-shaped slider, and a second spring is disposed on the outer wall of the sliding rod, positioned between the pressing column and the wedge-shaped slider. This invention, through the cooperation of the first lock, the second lock, the wedge-shaped slider, the bottom rod, the pressing column, the second spring, and the second sliding rod, achieves the effect of fixing and removing the mold, solving the problem of inconvenient mold replacement during plastic injection molding and improving mold replacement efficiency.

[0004] The aforementioned plastic processing mold has a base with a support column, and a main board is fixedly installed on the top of the support column. The main board, base, and support column form a rectangular structure, and the mold is located inside this rectangular assembly. During the removal and placement of the molded product, the support column and main board on the rectangular assembly obstruct this movement, hindering the removal of the plastic product. Furthermore, a cutting mechanism is located around the mold. A motor in the cutting mechanism drives a cutting tool to rotate around the mold, thereby cutting off excess plastic around the mold. However, the molded plastic product is relatively hard, and the high speed of the cutting tool can easily cause the edges of the plastic product to crack and make it difficult to cut. Therefore, we provide a plastic processing mold to solve the problems mentioned above. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-5 This utility model is a mold for plastic processing, including a lower mold base 1 and an upper mold base 3, and a displacement component 2 for connecting the lower mold base 1 and the upper mold base 3. The height of the upper mold cover 3 can be raised or lowered by the electric rod 203 in the displacement component 2, thereby achieving the effect of opening and closing. The upper mold cover 3 can be horizontally moved by the electric rod 202, thereby facilitating the removal of the plastic blank in the lower mold base 1.

[0031] Specifically, the bottom of both the left and right ends of the lower mold base 1 is provided with a sliding groove 103. The lower mold base 1 is slidably connected to the slider 201 in the displacement assembly 2 through the sliding groove 103. The side wall of the slider 201 is provided with a side hole 201a for connecting with the electric rod 202. The upper side wall of the slider 201 is fixedly installed with a fixing bracket 201b for connecting with the electric rod 203. The top side wall of the electric rod 203 is also connected to the upper mold cover 3 through a mounting post 304.

[0032] Furthermore, a sealing groove 101 is provided at the edge of the upper side wall of the lower mold base 1, and the sealing groove 101 is also connected to the sealing ring 303 at the bottom of the upper mold base 3. A casting pipe 102 is also fixedly installed on the upper side wall of one end of the lower mold base 1, and a casting pipe 2 302 is installed in the upper mold base 3 corresponding to the casting pipe 102.

[0033] The operation process of this embodiment is as follows: When it is necessary to open the mold, that is, when it is necessary to open the upper mold cover 3, the electric rod 203 extends and pushes the upper mold cover 3 on the shaft end of the electric rod 203 upward until the sealing ring 303 disengages from the sealing groove 101 in the lower mold seat 1. At this time, the upper mold cover 3 disengages from the lower mold seat 1. Then, the electric rod 202 retracts and pulls the slider 201 to slide in the slide groove 103. At this time, the electric rod 203 pushes the upper mold cover 3 to move to the side of the lower mold seat 1 to expose the lower mold seat 1, so that the cast plastic blank can be easily taken out from the lower mold seat 1.

[0034] Example 2

[0035] Please see Figure 6 Based on embodiment 1, a scraping assembly 4 is also provided. The battery 401 can provide power to the heating rod 404, which heats the scraper 405. The heated scraper 405 scrapes the plastic blank, thus avoiding damage to the main body of the plastic blank.

[0036] Specifically, a second sliding groove 301 is provided at the edge of the upper mold cover 3. The upper mold cover 3 slides and engages with the outer wall of the protective sleeve 401a that is snapped onto the outer wall of the battery 401 in the scraping assembly 4 through the second sliding groove 302. The upper side wall of the protective sleeve 401a is covered with a top cover 402. The bottom of the protective sleeve 401a and the battery 401 are connected to the heating rod 404 through a connecting post 403. A scraper 405 can also be detachably fixedly installed on the side wall of the heating rod 404.

[0037] Furthermore, the upper and lower ends of the protective sleeve 401a are also fitted with retaining rings 401b, and the protective sleeve 401a is connected to the upper mold cover 3 through the retaining rings 401b. The scraper 405 is set facing the upper mold cover 3. The upper side wall of the top cover 402 is also fixedly installed with a pull ring 402a, and the retaining rings 401b are respectively set at the upper and lower ends of the slide groove 301.

[0038] The operation process of this embodiment is as follows: When in use, the battery 401 provides power support to the heating rod 404, and then the heating rod 404 works. When it works, it generates a lot of heat. Part of this heat will heat the scraper 405. After the scraper 405 is heated, hold the pull ring 402a and push the protective sleeve 401a to slide in the slide groove 301. At this time, the scraper 405 is always facing the side of the upper mold cover 3 and the lower mold seat 1, and thus removes the excess plastic blank overflowing from the joint of the upper mold cover 3 and the lower mold seat.
