Description

A sensor injection mold

technical field

The utility model relates to the field of injection molds, in particular to a sensor injection mold.

Background technique

The sensor includes an outer injection molded housing and a copper sheet arranged in the injection molded housing. One end of the copper sheet protrudes from the housing, and the other end of the housing is provided with an inner cavity, as shown in FIG. 1 . During the injection molding process of the sensor, the copper sheet needs to be pre-set in the mold cavity, and then injection molded. In the production and processing of existing molds, the mold cavities are all arranged horizontally, which is more conducive to the forming of the sensor housing. However, the mold cavity set horizontally is very inconvenient for the placement of the copper sheet, the operating space is small, and the view is not good, so the copper sheet cannot be placed in the accurate area quickly, which reduces the qualified rate of the product. At the same time, the existing flow channel design cannot well realize multiple parts in one mold, and the production efficiency is low.

Formwork, the upper mold core is provided with an upper mold core, and a group of upper mold cavities are arranged on the upper mold core, and the lower mold assembly includes a bottom plate, a vertical plate, a lower mold backing plate and a lower mold plate that are sequentially superimposed and fixed, and the lower mold plate A lower mold core is arranged inside, and a set of lower mold cavities matching with the upper mold cavity is arranged in the lower mold core; a slider is also arranged on the side of the lower mold plate located on the lower mold core, and the slider is connected with a set of core columns through a pin shaft. One end of the core column is placed in the upper mold cavity and the lower mold cavity; the slider is also provided with a guide groove, and the upper mold assembly is provided with an inclined guide column that cooperates with the guide groove to drive the slider to slide.

Further, the inner wall of the guide groove is also provided with a retractable stopper, the end surface of the stopper located inside the guide groove is a vertical step surface, and the end surface located outside the guide groove is a slope structure. There are two guide grooves and inclined guide posts arranged side by side.

Further, the inner wall of the guide groove is provided with a stopper installation hole, a spring is arranged in the stopper installation hole, and the stopper is pressed onto the spring. A pair of stoppers are symmetrically arranged on the left and right inner walls of the guide groove.

In order to accurately locate the placement position of the copper sheet, one end of the upper mold cavity is also provided with a copper sheet upper limit column, and one end of the lower mold cavity is provided with a lower limit column cooperating with the upper limit column, the upper limit column and the lower limit column Grooves matching the copper sheets are provided on the posts, and the total height of the grooves on the upper limit post and the lower stop post is not greater than the thickness of the copper sheet. The end of the core column is provided with a copper sheet placement hole, and a copper sheet positioning bar is arranged in the copper sheet placement hole, and a placement hole for placing the copper sheet is left between the copper sheet placement hole and the copper sheet positioning bar.

In order to make the feeding of each mold cavity uniform, four upper mold cavities and lower mold cavities are arranged side by side, and a distribution flow channel is arranged in the lower mold core, and the middle position of the distribution flow channel communicates with the main flow channel. One end of the runner is located between the first and second mold cavities, the other end is located between the third and fourth mold cavities, and the end of the distribution runner communicates with each mold cavity through a slot.

For the convenience of taking parts and turning over the core column, a bottom needle plate and a face needle plate are also arranged on the bottom plate, and a set of first thimbles and a set of second thimbles are fixed between the bottom needle plate and the face needle plate. The top of the first thimble is located under the lower mold cavity, and the top of the second thimble is located under the stem.

Beneficial effects of the utility model: the utility model pulls the slider to move through the cooperation of the guide groove and the inclined guide column, thereby driving the core column together with the slider to move, so that the core column is separated from the sensor housing after injection molding, which is convenient The sensor is taken out, the structure is simple, and the operation is convenient. For the telescopic block in the guide groove, when the mold is opened, the inclined guide post cooperates with the step surface to push the slider to be removed. The downward pressure makes the block retract after overcoming the spring force, so that when the mold is completely closed, the inclined guide post can return to the inner side of the block, so that the slider can be pushed away when the next opening is made. The structure design is exquisite and the mutual cooperation Stable, and the structure is simple and compact. The upper and lower limit posts of the shrapnel can clamp the copper sheet when the mold is closed to ensure that the copper sheet will not move during injection molding, and the grooves on the upper and lower limit posts can align the copper sheet in the length and width directions. The location is limited, and the copper sheet is convenient and simple to place. The first thimble can push the sensor out from the lower mold cavity, which is convenient for taking parts. At the same time, the second thimble can push the stem out, so that the stem rotates around the pin connected to the slider, and the core The end of the column provided with the copper sheet placement hole is lifted up to facilitate the placement of the copper sheet when the mold is opened. The distribution channel structure is more conducive to the molding of injection molded parts, the flow of liquid material is more uniform, and the molding effect is better.

The utility model will be described in detail below in conjunction with the accompanying drawings and embodiments.
