Description

A kind of front mold row position tripping mechanism

technical field

The utility model relates to the field of plastic molds, in particular to a tripping mechanism for a front mold position.

Background technique

Plastic mold is a tool that is matched with plastic molding machines in the plastic processing industry to give plastic products a complete configuration and precise size. The plastic first heats the plastic in the barrel of the injection machine to make it melted by heat, and then, driven by the screw or plunger of the injection machine, enters the cavity of the plastic mold through the nozzle of the injection machine and the pouring system of the mold, and the plastic is cooled and hardened to form and remove. The molded product is obtained. With the development of modern industry, the application of plastic molds has become more and more extensive. In automobiles, electronics, instrumentation, home appliances, aerospace, building materials, electrical machinery and communication equipment and other products, most parts and components must be processed and formed by plastic molds. . The high-precision, high-complexity, high-consistency, high-productivity and low-consumption performance of parts formed by molds is unmatched by other processing and manufacturing methods. To a large extent, the mold determines the quality, efficiency and development capability of the product.

At present, the structure of plastic products is more diversified and complicated than before. Some plastic products have the inverted position in the upper mold, and it is necessary to design the front mold position to release the mold normally. The front mold position mechanism means that the position is set on the front mold side, so it must be ensured that the travel position completes the parting or core-pulling action before the mold is opened, or some mechanisms are used to keep the travel position with the glue for a period of time when the mold is opened. The horizontal position of the piece remains unchanged and the side core pulling action is completed. When the product has special requirements and the position of the undercut is deep and the stroke is long, the use of a general mechanical front mold slider will make the product undercut incompletely, and the product will be stuck when the mold is opened, resulting in the product being deformed and scrapped. Therefore, the mechanical front die slider cannot meet the needs of this structure. Therefore, improvement is required.

Utility model content

The purpose of this utility model is to provide a front mold travel position tripping mechanism to solve the above problems.

The utility model realizes the above-mentioned purpose through the following technical solutions:

A front mold position tripping mechanism, comprising correspondingly arranged mold A plate and mold B plate, the mold A plate is provided with a front mold core; the mold B plate is provided with a rear mold core; the front mold The upper part of the kernel is provided with a front mold insert; a cavity is arranged between the front mold insert and the rear mold kernel; it also includes a guide block and a front mold position; the guide block is arranged on the front mold insert The front mold row is set on the left side of the guide block, and its upper left side has a boss for forming product undercuts, and is in contact with the cavity; the guide block and the front mold Row position sliding connection; a driving device for pulling the guide block is arranged under the front mold core, and by pulling the guide block downward, the front mold row position moves to the right, so as to be separated from the product Upside down.

Further, a guide rail is provided on the left side of the guide block; a guide rail block corresponding to the guide rail is provided on the right side of the front die row position.

Further, the front mold insert is fixed on the upper part of the front mold core by bolts.

Further, the driving device is an oil cylinder.

The beneficial effect of the utility model is that a guide block and a front mold position are provided; the guide block is arranged below the front mold insert; the front mold position is set on the left side of the guide block, The upper left side is provided with a boss for forming a product inversion and is in contact with the cavity; the guide block is slidably connected with the front mold position; the front mold core is provided with a guide block for pulling the guide block. The driving device of the block moves the front die row position to the right by pulling the guide block downwards, thereby disengaging from the product undercut. When the mold is closed, the upper left side of the front mold position is in close contact with the cavity, and the product can be inverted after injection molding; when the mold is opened, the oil cylinder pulls the guide block to move down, and because The guide block is slidably connected with the front mold row position, and the front mold row position moves to the right, and is separated from the product inversion; it can realize the release of the inversion with a deep position and a long stroke, and the tripping stroke is stable , improve safety performance; effectively improve production efficiency, reduce maintenance costs and maintenance costs.

Detailed ways

In order to make the above objects, features and advantages of the present utility model more clearly understood, the specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings. It should be noted that the drawings of the present invention are all in simplified form and in inaccurate scales, and are only used to facilitate and clearly assist the purpose of explaining the embodiments of the present invention.

As shown in FIGS. 1 to 2 , a front mold position tripping mechanism includes a correspondingly arranged mold A plate and a mold B plate, and the mold A plate is provided with a front mold core 2; above the mold B plate There is a rear mold core 1; the upper part of the front mold core 2 is provided with a front mold insert 3; a cavity is provided between the front mold insert 3 and the rear mold core 1; it also includes a guide slider 5 and The front mold position 4; the guide block 5 is arranged under the front mold insert 3; the front mold position 4 is arranged on the left side of the guide block 5, and its upper left side has a product undercut. The boss 42 is in contact with the cavity; the guide block 5 is slidably connected with the front mold position 4 ; the front mold core 2 is provided with a driving device for pulling the guide block 5 , by pulling down the guide block 5, the front mold position 4 moves to the right, so as to be separated from the product undercut; the front mold insert 3 is fixed on the front mold core 2 by bolts 7 upper.

As shown in FIG. 3 , a guide rail is provided on the left side of the guide block 5 ; a guide rail block 41 corresponding to the guide rail is provided on the right side of the front mold position 4 .

The working flow of a front mold travel position release mechanism of the present utility model is as follows:

Continuing to refer to FIG. 1 , firstly, the mold is closed. At this time, the upper left side of the front mold position 4 is in close contact with the mold cavity. 42 , thereby forming a product undercut 61 . Then start the mold opening process, the mold A plate, the front mold core 2, the front mold insert 3, the mold B plate and the rear mold core 1 do not move, and the oil cylinder pulls the guide slide The block 5 moves downward, and because the guide block 5 and the front mold position 4 are slidably connected through the guide rail and the guide rail block 41, the guide rail and the guide rail block 41 cooperate with each other, In the process of making the guide block 5 move downward, the front mold position 4 is driven to move to the right, and the upper left side of the front mold position 4 is separated from the cavity, thereby detaching from the product inversion 61, and the state at this time is as follows shown in Figure 2. When the mold is closed next time, the oil cylinder pushes the guide block 5 to move upward, so that the front mold position 4 moves to the left to reset, and makes the boss 42 abut against the cavity. In the next injection molding A product undercut 61 can be formed.
