Some special products are provided with a multi-PIN structure shown in figure 1, are placed one by one in the conventional forming at present, are contrary to the forming period, not only have long placing time period, but also have the risk of being misplaced or missed at high temperature and under the mold temperature, and in the placing process, because the mold temperature is higher, the risk of scalding limbs of a placing person exists, in order to avoid the problems, the problem needs to be considered in the early design of the mold, so that the placing time of the PIN can be shortened, the problem that the missed placing part affects the forming period can be avoided, and even if the problems occur, the PIN can be found and corrected.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the problem of how to shorten the placement cycle of inserts in a multi-insert product is solved.

In order to solve the technical problem, the technical scheme of the utility model is to provide a multi-insert product mold structure, which comprises a movable mold and is characterized in that a plurality of insert modules corresponding to the positions of products to be injection molded are arranged in a mold cavity of the movable mold, and positioning columns are uniformly distributed on the movable mold around the insert modules; the insert module comprises an insert module body, the lower portions of two ends of the insert module body are respectively provided with a platform, the platforms are provided with a plurality of clamping grooves used for clamping the lower portions of inserts, the upper surfaces of two ends of the insert module body are provided with a plurality of grooves used for limiting the positions of the upper portions of the inserts, and the clamping grooves and the grooves are arranged in a one-to-one correspondence mode.

Preferably, the insert is a PIN of an "L" type structure.

Preferably, a clamping groove is formed in the lower portion of one side of the insert module body of one of the insert modules, and a groove is formed in the upper surface of one side of the insert module body.

Preferably, a plurality of joint connector grooves for placing joint connectors are further arranged in the die cavity of the movable die.

The utility model has the advantages of simple structure, safety, reliable shorten the placing period of inserts, improve production efficiency, solved the problem of placing the period length of inserts at present. The utility model discloses a structure can be gone on in step with the shaping of product, realizes the automatic inserts of placing, the inside including mould benevolence is equipped with the inserts module, and the both ends of inserts module all are equipped with the mold insert, according to the volume production demand, make many sets and exchange the mold insert, to similar use PIN needle product, especially many PIN needle products, more effective more convenient.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model relates to a many inserts product mould structure, as shown in FIG. 10, 11, it includes movable mould 1, be equipped with a plurality of insert module 2 corresponding with the product position that will mould plastics in the die cavity of movable mould 1, insert module 2 is used for fixed inserts, the equipartition has reference column 3 around insert module 2 on movable mould 1, reference column 3 is used for passing the hole on the product base 4 and with product base 4 spacing, as shown in FIG. 7, insert module 2 includes insert module body 24, the lower part at insert module body 24 both ends all is equipped with platform 22, be equipped with a plurality of draw-in grooves 23 that are used for blocking the inserts lower part on the platform 22, the upper surface at insert module body 24 both ends is equipped with a plurality of recesses 21 that are used for restricting insert upper portion position, draw-in groove 23 and recess 21 one-to-one-for-exchanging the type simplification mould mold insert, it is the PIN needle of "L" type structure, the lower part of one of insert module body 24 one side of one of insert module 2 is equipped with draw-in groove 23, the upper surface of insert module body 24.

The production injection molding process of the multi-PIN structure is as follows:

firstly, forming a product base 4 in a movable die, respectively fixing a plurality of groups of PIN needles 6 at two ends of a plurality of insert module bodies 24, as shown in fig. 8 and 9, then placing the insert module bodies 24 with the PIN needles 6 in a die cavity of the movable die 1, as shown in fig. 10 and 11, placing joint connectors 7 in the die cavity, as shown in fig. 4, placing the insert module bodies 24 in the die cavity, forming a one-shot product, as shown in fig. 2, placing copper sheets and magnetic steel 8 shown in fig. 5 after being demoulded, placing the insert module bodies in a two-shot die cavity again, as shown in fig. 3, simultaneously placing heat radiating fins 5 shown in fig. 6 into the two-shot die cavity, finally, demoulding to obtain a good product, and forming a multi-PIN needle structure, as shown in fig. 1.

During placement, the key for ensuring that a plastic part can be smoothly demoulded is to pay attention to the placement regularity of the insert, so that the requirement on the matching tolerance of the mold and the insert is strict, the insert is pulled due to over-tightness, burrs are generated due to over-looseness, the insulativity of the copper sheet is greatly reduced, and the appearance is also poor.
