Improved plastic mold applied to plastic cover of printer

Abstract

The invention relates to an improved plastic mold applied to a plastic cover of a printer. The mold comprises an upper mold body, a mold core, a lower mold body, a mold cavity and buffer pads; the upper mold body and the lower mold body are vertically opposite to each other and are movably arranged; the mold core is arranged at the lower part of the upper mold body; the mold cavity is formed in the upper part of the lower mold body; the mold core and the mold cavity are arranged at intervals in a clamped mode; the lower surface of the upper mold body is provided with an upper mold body attaching surface attached to the lower mold body; the upper surface of the lower mold body is provided with a lower mold body attaching surface attached to the upper mold body; the buffer pads are arranged on opposite surfaces of the upper mold body attaching surface and the lower mold body attaching surface in a matched mode; and the buffer pads have the buffering function. According to the improved plastic mold applied to the plastic cover of the printer, because buffering and sealing pads are arranged, the service life is greatly prolonged, and the production cost of an enterprise is reduced; and meanwhile, because the upper mold body and the lower mold body do not generate great noise when the upper mold body and the lower mold body make contact, noise pollution is avoided, the working environment of operators is improved, the working efficiency is improved, and convenience is brought to production enterprises.

Description

technical field [0001] The invention belongs to the technical field of plastic molds, in particular to an improved plastic mold applied to the plastic cover of a printer. Background technique [0002] With the rapid development of the polymer plastic industry, the scope of application of polymer plastic products is also expanding, and plastic shell covers are also widely used in printers. However, plastic products pollute the environment very seriously. Due to environmental problems and energy problems It is becoming more and more severe, and waste plastics are usually recycled and reused now. Plastic molds are tools for producing plastic products. The working principle is to inject molten plastic into the molding cavity, let it cool and shape in the cavity, and then separate the upper and lower molds. The product is ejected from the mold cavity via an ejection system. [0003] At present, there are various forms of plastic molds. Most of the molds include an upper mold and...

Problems solved by technology

[0003] At present, there are various forms of plastic molds. Most of the molds include an upper mold and a lower mold. Since the upper mold and the lower mold of the mold need to be frequently attached and separated during use, the upper mold and the lower mold When laminating, the two are often set by a large force. Due to the long-term use of the upper mold and the lower mold, the bonding surface of the two will be greatly worn, and the shortening will be greatly shortened. The service life of the mold has been shortened, and the production cost of the enterprise has been increased; at the same time, the bonding surfaces of the upper mold and the lower mold are mostly made of metal, and when the two are in contact, sometimes a lot of noise will be generated, which is not conducive to the health of the operators. , also produced noise pollution, which brought inconvenience to the production enterprises

[0004] In addition, in order to prevent the refractory materials in waste plastics from blocking the injection port, some existing injection molds are equipped with filter screens and slag collection tanks, which are used to collect filtered refractory materials, such as patent publication CN204295963U For the disclosed plastic mold, due to the limited capacity of the slag collecting tank, the slag collecting tank is very difficult to clean when the amount of filtered refractory material is large and the slag collecting tank is overflowed. This has brought great inconvenience to the users, and they can only replace new molds and discard them, which greatly wastes energy, which not only increases the production cost of the enterprise, but also greatly reduces the production cost of the enterprise. efficiency
