Abstract

The utility model discloses a mold for pins of an encapsulated product. Comprises two guide pins, a movable die insert and a small contact pin insert; a groove is formed in the top surface of the movable die insert, a slot is formed in a position corresponding to the product insert, and a small insert of a contact pin is arranged in the slot; a plurality of slot groups are uniformly distributed in the small contact pin insert, and the slot groups correspond to the contact pins of the product one by one; the movable die insert drives the small insert of the contact pin to move upwards to be separated from a product in the demolding process due to the clamping connection of the movable die insert and the small insert of the contact pin, so that the product contact pin is prevented from being damaged in the injection molding or mold opening process of the mold.

Description

Mould for rubber-coated product contact pin

Technical Field

The utility model relates to a mold for pins of an encapsulated product.

Background

The mould is used for producing various moulds and tools of the needed products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods in industry. In short, a mold is a tool used to make a molded article, which is made up of various parts, with different molds being made up of different parts.

At present, an injection molding rubber coating mold is adopted when a product containing the contact pin is produced, but the contact pin is thin and positioned on the outer side of the product, so that the contact pin is easily damaged in the demolding process of the product.

Disclosure of utility model

The utility model aims to provide a die-casting iron core trimming and pouring gate integrated structure with high universality.

The technical scheme for realizing the utility model is as follows:

The mold for the pin of the encapsulated product comprises two guide pins, a movable mold insert and a small pin insert; a groove is formed in the top surface of the movable die insert, a slot is formed in a position corresponding to the product insert, and a small insert of a contact pin is arranged in the slot; a plurality of slot groups are uniformly distributed in the small insert of the contact pin, and the slot groups correspond to the contact pins of the product one by one.

The slot group comprises an upper slot positioned above and a lower slot positioned below, and the upper slot corresponds to the lower slot one by one.

The small insert pressing plate is arranged in the groove at the rear end of the small insert of the contact pin and is matched with the groove through the bolt at the rear end.

The two guide pins are oppositely arranged at two ends of the bottom surface of the movable die insert.

A strip-shaped mounting groove is further formed between the upper slot and the corresponding lower slot, and a copper contact pin baffle is arranged in the strip-shaped mounting groove.

The mounting groove is formed in the center of the upper portion of the inserting groove group, the mounting groove is located between the two upper inserting grooves in the center, and the mounting groove is matched with the small insert positioning block on the side face of the small insert pressing plate.

By adopting the technical scheme, the insert groove group is used for placing the product pins, and because the movable die insert is clamped with the small insert of the pins, the movable die insert drives the small insert of the pins to move upwards to separate from the product in the demolding process, so that the product pins are prevented from being damaged in the injection molding or die sinking process of the die.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present utility model more clear, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It will be apparent that the described embodiments are some, but not all, embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without creative efforts, based on the described embodiments of the present utility model fall within the protection scope of the present utility model.

Referring to fig. 1, which shows a schematic view of the structure of the application, the pin mold for encapsulated products comprises two guide pins 1, a movable mold insert 2 and a pin small insert 3; the top surface of the movable die insert is provided with a groove 4, a slot 5 is arranged at the position of the groove corresponding to the product pin 7, and a small pin insert 3 is arranged in the slot; a plurality of slot groups are uniformly distributed in the small insert of the contact pin, and the slot groups 6 are in one-to-one correspondence with the contact pins of the product. The movable die insert drives the small insert of the contact pin to move upwards to be separated from a product in the demolding process due to the clamping connection of the movable die insert and the small insert of the contact pin, so that the product contact pin is prevented from being damaged in the injection molding or mold opening process of the mold.

The slot group comprises an upper slot 8 positioned above and a lower slot 9 positioned below, and the upper slots and the lower slots are in one-to-one correspondence. The lower slots are in one-to-one correspondence with the contact pins on the product, so that the contact pins on the product can be conveniently fixed.

The groove at the rear end of the small insert of the contact pin is internally provided with a small insert pressing plate 10, and the small insert pressing plate is matched and installed with the groove through a bolt at the rear end. The small insert of the contact pin and the small insert pressing plate are of an integrated structure and are fixed in the groove through the small insert pressing plate, so that the small insert of the contact pin is arranged in the groove.

The two guide pins are oppositely arranged at two ends of the bottom surface of the movable die insert. The guide pin is used for guiding the movable mold insert.

A strip-shaped mounting groove 11 is further arranged between the upper slot and the corresponding lower slot, a copper pin baffle is arranged in the strip-shaped mounting groove, and the copper pin baffle 12 extends from the leftmost slot to the rightmost slot. The copper contact pin baffle blocks the contact pin of the product, thereby playing a role in limiting the contact pin.

The center of the upper part of the slot group is provided with a mounting slot 13, the mounting slot is positioned between the two upper slots in the center, and the mounting slot is matched with a small insert positioning block 14 on the side surface of the small insert pressing plate for use; the small insert of the contact pin is clamped on the small insert pressing plate, and the small insert of the contact pin is fixed.

The outer side surface of the middle part of the small contact pin insert is provided with two steps, and the inclined surface of each step is matched with the section of a product, so that the matched installation of the product is facilitated.
