technical field

The utility model relates to the technical field of moulds, in particular to a rubber-coated mold set based on an automatic water cutting port.

Background technique

In the production of plastic products, the product obtained after the entire injection molding process is often connected to the flow channel, and manual trimming is required to separate the product from the flow channel, which not only causes labor waste, but also reduces production efficiency.

At present, there are several difficult problems to deal with the side-feed glue punching nozzle of the shell product: the nozzle cannot be cut off automatically, and the production efficiency is low. After the product is formed, it is necessary to make a jig and then cut the sprue separately, which increases the labor cost. After mass production, the cutting edge of the punching jig often causes unstable production due to wear and tear. , secondary processing is required, and after a certain amount of subsequent mass production, the tool needs to be replaced in time to ensure the stability of mass production.

Utility model content

In order to solve the above problems, the utility model relates to a cutting knife provided on the front mold body. After the product has been formed for many times, the nozzle is cut off by the cutting knife at the same time during the last forming, which is convenient for operation and saves money. Manpower and material resources, improve production efficiency based on automatic water cutting mouth plastic overmolding mold set.

The technical solution adopted in the utility model is: a rubber-coated mold set based on an automatic water cutout, including a front mold body and a rear mold body, and the front mold body and the rear mold body cooperate to form a flow channel groove and a molding cavity , the runner groove is provided with a high bump near the molding cavity, and the front mold body is movably embedded with a cutter corresponding to the high bump position.

A further improvement to the above solution is that the runner grooves are arranged in an annular connection, and several groups of the molding cavity are distributed between the front mold body and the rear mold body and are connected to the runner grooves.

A further improvement to the above solution is that the high bumps are arranged at both ends of the connection between the runner groove and the molding cavity.

A further improvement to the above solution is that the cutters are provided with several groups, which are distributed on the front mold body and correspond to the positions of each group of high bumps.

A further improvement to the above solution is that the cutter is a cylindrical cutter, and a knife edge is provided near the position of the high bump, and the shape of the knife edge matches the corresponding position of the molding cavity.

A further improvement to the above solution is that the rear mold body is provided with an escape position corresponding to the cutting knife.

The beneficial effects of the utility model are:

In the first aspect, the front mold body and the rear mold body are set, and the runner groove for introducing raw materials and the molding cavity for molding the product are formed by the combination of the front mold body and the rear mold body. The product can be molded by fluid, the molding effect is good, and it is easy to use; secondly, the runner groove is provided with high bumps near the molding cavity, and the front mold body is equipped with a cutter corresponding to the high bumps. Specifically, after the product passes through twice or After multiple moldings, the mold is used for final molding to ensure that the nozzle on the runner groove is cut off by the cutter at the same time during the molding process, and the cutting effect is good and the work efficiency is improved.

In the utility model, by setting a cutter on the front mold body, after the product has been formed for many times, the nozzle is cut off by the cutter at the same time during the last forming, which is convenient for operation, saves manpower and material resources, and improves production efficiency .

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, an overmolding mold set based on an automatic water cutout includes a front mold body 110 and a rear mold body 120, and the front mold body 110 cooperates with the rear mold body 120 to form a runner groove 130 and a molding cavity 140, the runner groove 130 is provided with a high bump 150 near the molding cavity 140, and the front mold body 110 is movably embedded with a cutter 160 corresponding to the high bump 150.

The rear mold body 120 is provided with a space 121 corresponding to the cutter 160, so that the cutter 160 can cut off the nozzle stably, so that the cutter 160 will not wear after cutting the nozzle, and the service life of the cutter 160 is improved.

The runner groove 130 is arranged in an annular connection. The molding cavity 140 is provided with several groups distributed between the front mold body 110 and the rear mold body 120 and connected to the runner groove 130. Specifically, multiple products can be molded at the same time. 130 connection molding is used to improve production efficiency.

The high bumps 150 are arranged at both ends of the runner groove 130 and the molding cavity 140, which is convenient for the connection and use of multiple products, and also facilitates the cutter 160 to cut off the nozzle, with high cutting efficiency, practical and reliable.

The cutting knife 160 is provided with several groups, which are distributed on the front mold body 110 and correspond to the position of each group of high bumps 150. Multiple groups are used to cut off the nozzles on both sides of the product at the same time, and the cutting effect is good.

The cutting knife 160 is a cylindrical cutting knife 160, which is provided with a knife edge 161 near the high bump 150. The shape of the knife edge 161 matches the corresponding position of the molding cavity 140, and the knife edge 161 that matches the molding cavity 140 is the product. After cutting, the quality of the product after cutting is guaranteed, and the effect of cutting the nozzle is good.

In the first aspect, the front mold body 110 and the rear mold body 120 are set, and the runner groove 130 for introducing raw materials and the molding cavity 140 for molding the product are formed by the combination of the front mold body 110 and the rear mold body 120, specifically It means that the product can be formed by introducing fluid after synthesis, with good molding effect and convenient use; secondly, the runner groove 130 is provided with high bumps 150 close to the molding cavity 140, and the front mold body 110 is set to correspond to the high bumps 150. The cutter 160 is specifically formed after the product has been molded twice or more times through the action of this mold, so as to ensure that the nozzle on the runner groove 130 is cut off by the cutter 160 during the molding process, and the cutting effect is good and the work efficiency is improved. .
