Description

Technical Field

[0001] This utility model relates to the field of plastic molds, and in particular to a movable precision positioning plastic mold structure. Background Technology

[0002] The movable precision positioning plastic mold structure is a mold architecture designed for high-precision plastic products. Its core lies in the coordinated operation of movable parts and a precision positioning system to achieve precise molding of complex plastic parts. This structure typically consists of two main parts: a fixed mold and a moving mold, supplemented by rigid positioning components such as high-precision guide pillars and bushings, positioning pins, and precision positioning blocks (such as conical positioning and jaw positioning) to ensure orientation accuracy during mold closing.

[0003] In the current positioning method, the front mold core mounting plate is fixed to the mold frame A plate with screws. After fixing, the front mold core mounting plate cannot move freely relative to the mold frame A plate. During the mold closing process, the rear block frame ultra-precision positioning component and the front block frame ultra-precision positioning component are fixed in position. When an assembly abnormality occurs, there is forced hard positioning, which leads to damage to the positioning parts and the forming mold core. Utility Model Content

[0004] The purpose of this invention is to provide a movable precision positioning plastic mold structure to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A movable precision positioning plastic mold structure includes a mold base plate A, a mold base plate B, and a mold base plate C, arranged from top to bottom. It also includes a rear mold guide sleeve positioning component for overall positioning and a front mold core mounting plate for molding. The front mold core mounting plate is installed in a groove in the mold base plate A. A molding core that mates with the front mold core mounting plate is disposed in the groove of the mold base plate A. Four front block frame ultra-precision positioning components are disposed in the groove of the mold base plate A, arranged symmetrically in pairs. A cover plate for pre-positioning the front mold core mounting plate is disposed on one side of the front mold core mounting plate on the mold base plate A. A spring support plate is installed on the cover plate.

[0007] The mold frame B plate is located on the lower side of the mold frame A plate. A rear mold core mounting plate is installed on the mold frame B plate corresponding to the position of the front mold core mounting plate. The two sides of the rear mold core mounting plate are fixedly installed on the mold frame B plate by the rear block frame ultra-precision positioning components. The rear block frame ultra-precision positioning components are correspondingly arranged with the front block frame ultra-precision positioning components. The rear mold guide sleeve positioning component passes through the mold frame B plate, the mold frame A plate, and the mold frame C plate.

[0008] Preferably, the front mold core mounting plate is fitted with the groove on the mold frame A plate with a clearance fit, and the clearance between the plate and the groove is 0.03mm.

[0009] Preferably, the cover plate is slidably connected to the mold frame A plate.

[0010] Preferably, the rear mold T-shaped precision positioning component is fixedly connected to the mold frame B plate.

[0011] Preferably, the front mold T-shaped precision positioning component is fixedly connected to the mold frame A plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In the initial stage of installation, the front mold core mounting plate is in a fixed gap state. During the mold closing process, the front block frame ultra-precision positioning component is driven by the rear block frame ultra-precision positioning component to freely correct and position the front mold core mounting plate, avoiding the forced hard positioning in the ordinary state and achieving a free precision positioning state.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-6 As shown, a movable precision positioning plastic mold structure includes a mold frame A plate 11, a mold frame B plate 13, and a mold frame C plate 14, which are arranged from top to bottom. It also includes a rear mold guide sleeve positioning component 1 for overall positioning and a front mold core mounting plate 8 for molding. The front mold core mounting plate 8 is installed in a groove in the mold frame A plate 11. A molding core 12 that matches the front mold core mounting plate 8 is provided in the groove in the mold frame A plate 11. A front block frame ultra-precision positioning component 6 for positioning the front mold core mounting plate 8 is provided in the groove in the mold frame A plate 11. There are four front block frame ultra-precision positioning components 6, which are symmetrical in pairs. A cover plate 10 for pre-positioning the front mold core mounting plate 8 is provided on one side of the front mold core mounting plate 8 on the mold frame A plate 11. A spring support plate 9 is installed on the cover plate 10.

[0027] The mold frame B plate 13 is located on the lower side of the mold frame A plate 11. The mold frame B plate 13 is equipped with a rear mold core mounting plate 7 corresponding to the position of the front mold core mounting plate 8. The rear mold core mounting plate 7 is fixedly mounted on the mold frame B plate 13 on both sides by the rear block frame ultra-precision positioning component 5. The rear block frame ultra-precision positioning component 5 is set in correspondence with the front block frame ultra-precision positioning component 6. The rear mold guide sleeve positioning component 1 passes through the mold frame B plate 13, the mold frame A plate 11, and the mold frame C plate 14.

[0028] Preferably, the front mold core mounting plate 8 is fitted with the groove on the mold frame A plate 11 with a clearance of 0.03mm.

[0029] Preferred configuration: Cover plate 10 is slidably connected to mold frame A plate 11.

[0031] Preferred: The front mold T-shaped precision positioning component 4 is fixedly connected to the mold frame A plate 11.

[0032] Working principle: The front mold core mounting plate 8 is installed into the mold frame A plate 11, and the cover plate 10 presses and fixes the front mold core mounting plate 8 onto the mold frame A plate 11;

[0033] At this time, the front mold core mounting plate 8 is in a free installation state with gaps, and the distance between the three sides is 0.03mm; one side is supported by the spring support plate 9.

[0034] The rear block frame ultra-precision positioning component 5 is fixedly installed on the rear mold core mounting plate 7; the front block frame ultra-precision positioning component 6 is fixedly installed on the front mold core mounting plate 8;

[0036] During continuous mold closing; the rear block frame ultra-precision positioning component 5 and the front block frame ultra-precision positioning component 6 begin to contact and position; because the front mold core mounting plate 8 is in a free installation state with gaps;

[0037] During the further mold closing process, the front mold core mounting plate 8 can be freely corrected and positioned by the rear block frame ultra-precision positioning component 5 driving the front block frame ultra-precision positioning component 6; thus avoiding the forced hard positioning in the normal state and achieving a free precision positioning state.
